Technical Field

The present invention relates to the field of special intelligent packaging equipment, in particular to automated intelligent packaging equipment for realizing rapid packaging of hand-rolled degradable plastic films.

Background Art

Plastic film roll is a kind of packaging material. Traditional plastic film rolls are generally made of materials such as polyethylene or polypropylene. With the deepening of social environmental protection concepts, many plastic film rolls made of polyester degradable plastics have appeared in recent years and have been widely used.

Since plastic film rolls have good tensile properties, puncture resistance and transparency, they are very common in the logistics and packaging industries, used to wrap and protect goods to prevent dust, moisture and physical damage. In the production and processing of plastic film rolls, they are mainly collected in a winding manner. After the plastic film rolls are wound into rolls according to the set length, they need to be externally packaged before they can be sent to the marking, coding and other processes, and then shipped out and transported.

In the prior art, when packaging a rolled plastic film hand roll, the packaging machine is mainly used to complete this operation. There are also various types of packaging machines on the market. For example, in the patent document with the patent publication number CN113501165A, a roll body material packaging device is disclosed, and its main structure includes a conveying structure, a packaging structure and a limiting structure. The limiting structure is fixedly connected to the conveying structure and is arranged on the upper side of the conveying structure. The packaging structure is arranged at the output end of the conveying structure, and the packaging structure cooperates with the output end of the conveying structure; the conveying structure includes a gantry, a limiting track and a slider. The limiting track is arranged on the inner side of the gantry and is fixedly connected to the gantry. The slider is slidably connected to the limiting track and is fixedly connected to the limiting structure.

It can be seen from the above-mentioned prior art that it mainly supports the conveying structure by utilizing a gantry and utilizes the cooperation between the limiting track and the slider to realize automatic conveying of the roll body material, thereby realizing improved efficiency in packaging the roll body material. However, this structure adopts a traditional film coating structure during packaging, and the overall film coating efficiency is low, and it is impossible to realize continuous and rapid packaging of rolled materials.

DETAILED DESCRIPTION

The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention. The specific structure of the present invention is shown in Figures 1 to 6.

Embodiment: An automated intelligent packaging device for realizing rapid packaging of hand-rolled degradable plastic film comprises a box body 1 with a side opening, a pair of pressing automatic packaging components being arranged in the middle of the internal space of the box body 1 with the side opening, and packaging film unwinding mechanisms 2 being symmetrically installed above and below the pressing automatic packaging components, respectively. The two packaging film unwinding mechanisms 2 cooperate to realize outer surface coating processing of a rolled plastic film hand-rolled 3 placed inside the pressing automatic packaging components, and a pushing and discharging mechanism is fixedly installed on the inner side wall of the rear baffle 4 of the box body 1 on the rear side of the pressing automatic packaging components, and the pushing and discharging mechanism is used for pushing the hand-rolled plastic film 3 after the outer surface coating is completed forward and dropping it onto the matching belt conveyor 5 for transportation to the downstream end sealing process.

In any of the above schemes, it is preferred that the automatic pressure packaging component is composed of two clamping and covering mechanisms that are symmetrical from top to bottom and spaced apart, and the two clamping and covering mechanisms are in relative or opposite movement in the working state, and the interiors of the two clamping and covering mechanisms are fixedly adsorbed with the outer packaging film 6 on the packaging film unwinding mechanism 2 from the upstream, and the outer packaging film 6 located inside the two clamping and covering mechanisms cooperates to achieve the outer surface coating of the rolled plastic film hand roll 3 placed therein.

The automatic pressure packaging component relies on the relative proximity of the clamping and covering mechanisms to achieve the packaging working state or the separated state after packaging. When the outer packaging film 6 is pulled into place, the clamping and covering mechanisms on both sides are controlled to be pressed into place, and then the negative pressure adsorption molding, roll product feeding, hot air sealing and cutting on both sides are completed. When the cutting is completed, the packaging action is completed. At this time, the two clamping and covering mechanisms are controlled to move away from each other, and then the pushing action is started. Finally, the material is dropped and continued to be transported downstream.

In any of the above schemes, it is preferred that the clamping and coating mechanism includes a fixedly arranged horizontal connecting seat 7, a negative pressure generator 8 is provided in the space between the outer packaging film conveying section at the corresponding position and the horizontal connecting seat 7, the negative pressure generator 8 is connected to the horizontal connecting seat 7 through a plurality of vertical adjusting cylinders 9, each of the vertical adjusting cylinders 9 is in a synchronous motion state, the end of the cylinder barrel of each of the vertical adjusting cylinders 9 is fixed on the horizontal connecting seat 7, the end of the piston rod is fixed on the surface of the negative pressure generator 8, an arc-shaped shaping seat 10 is fixedly installed on the inner side of the negative pressure generator 8, and a negative pressure generator 8 is provided on the arc-shaped shaping seat 10 along the arc-shaped shaping seat 10. Its surface is provided with a plurality of negative pressure adsorption channels 11 which are arranged through its radial thickness direction. The outer end of each negative pressure adsorption channel 11 is connected to the corresponding port of the negative pressure generator 8 through an existing connecting pipe with multiple channels (not shown in the figure) during operation. Each negative pressure adsorption channel 11 cooperates with the negative pressure generator 8 to generate negative pressure and adsorbs the outer packaging film 6 in a relaxed state on its inner side into the interior and keeps it positioned and formed on the arc-shaped inner surface 12 of the arc-shaped forming seat 10. Heat sealing and cutting units are respectively installed at both ends of the negative pressure generator 8, and the heat sealing and cutting units are used to cut off excess outer packaging film 6.

The pressing and wrapping mechanism relies on the negative pressure generator 8 and the matching multi-way hose pipeline to be sealed and connected with the ports of the corresponding negative pressure adsorption channels 11 on the arc-shaped shaping seat 10. By controlling and starting the negative pressure generator 8, the inner mouth of the negative pressure adsorption channel 11 can be formed with negative pressure wind force, so that the outer packaging film 6 in a relaxed state on the inner side can be adsorbed toward the inner curved surface of the arc-shaped shaping seat 10 close to the current side, and finally the corresponding relaxed sections of the two layers of outer packaging film 6 are firmly adsorbed on the corresponding inner curved surfaces of the arc-shaped shaping seat 10. At this time, the bending radians of the two layers of outer packaging film 6 are in relatively opposite directions and form a cylindrical packaging space. Controlling the working gears of the two negative pressure generators 8 can achieve smoothness during negative pressure adsorption and firmness after negative pressure adsorption positioning. After the packaging space is formed, the rolled plastic film hand roll 3 to be packaged can be fed into the packaging space through external feeding equipment or manual feeding, waiting for packaging.

In any of the above schemes, it is preferred that the heat sealing and cutting unit includes a connecting seat 13 fixedly installed at the corresponding end of the negative pressure generator 8, a rotating motor 14 is fixedly installed on the front side wall of the connecting seat 13, and a heat pressing roller 15 with a plurality of pressing teeth on the surface is fixedly installed on the motor shaft of the rotating motor 14, the outer side wall of the heat pressing roller 15 is pressed against the surface of the corresponding outer packaging film 6, and a cutting knife 17 is arranged in the through mounting groove 16 of the heat pressing roller 15 along the width direction of the outer packaging film 6, the cutting knife 17 is connected to the end face of the through mounting groove 16 through a cutting cylinder 18, and the cutting knife 17 is preheated by electric heating. When the outer packaging film 6 needs to be cut, the cutting cylinder 18 controls the cutting knife 17 to extend and tilt to complete the tilted pressing and cutting of the outer side of the outer packaging film 6 after the pressing and fixing, and controls the cutting knife 17 to be tilted at an angle of 20°-30° with the vertical direction, and the cutting knives 17 on both sides are symmetrically arranged in the cutting state.

In any of the above schemes, it is preferred that the two opposite heat-sealing and cutting units' two heated heat-sealing rollers 15 in a high-temperature state rotate and press together to achieve heat-sealing treatment of the two opposite outer packaging films 6 .

After the plastic film hand roll 3 to be packaged is sent into the packaging space, the external matching controller controls the heating of the hot pressing roller 15, and at the same time controls the heating temperature to reach an appropriate temperature. At this time, the corresponding four rotating motors 14 are controlled to realize a small range of rotation in the forward and reverse directions to control the two sides of the two layers of outer packaging film 6 to be pulled slightly 5-10 times, and hot pressing and heat sealing are achieved in the process of pulling, and finally it is ensured that the ends of the two layers of outer packaging film 6 on the left and right sides of the rolled plastic film hand roll 3 to be packaged are in a bonded state. At this time, each rotating motor 14 is controlled to rotate to an appropriate position and adjust to the cutting station, and the cutting cylinder 18 in an inclined position is controlled to extend and drive the corresponding cutting knife 17 to cut the film outside the current thermal bonding part of the two layers of outer packaging film 6 to complete the cutting operation.

In any of the above schemes, it is preferred that a main reversing roller 19 is respectively provided on the left side of each of the crimping and coating mechanisms, and the central axis of each of the main reversing rollers 19 is respectively movably inserted in the rotating hole corresponding to the rear baffle 4, and a secondary reversing roller 21 is movably hingedly installed in the mounting wheel frame 20 at the left end of the horizontal connecting seat 7 corresponding to each of the main reversing rollers 19. The outer packaging film 6 unwound from the packaging film unwinding mechanism 2 is transported horizontally to the right after being reversed by the secondary reversing roller 21 and the main reversing roller 19 on the corresponding side, and is formed and positioned after passing through the corresponding crimping and coating mechanism.

By coordinating the reversing of the main reversing roller 19 and the auxiliary reversing roller 21, smoothness can be achieved when the outer packaging film 6 is tensioned and conveyed. At the same time, the two main reversing rollers 19 that are relatively docked can cooperate to clamp and convey the two layers of outer packaging film 6 that enter, ensuring the smoothness of subsequent transportation.

In any of the above schemes, it is preferred that a clamping, pulling and guiding mechanism is arranged on the right side of the automatic pressure packaging component and is coplanar with its center plane, and the clamping, pulling and guiding mechanism pulls the upper and lower layers of outer packaging film 6 on its left upstream side to the right to complete a set length as needed. When the upper and lower layers of outer packaging film 6 are pulled into place, the two clamping and covering mechanisms are controlled to heat-seal the upper and lower layers of outer packaging film 6 in the current area and complete cutting after sealing.

The clamping, pulling and guiding mechanism is mainly used to continue pulling the two layers of outer packaging film 6 remaining on the left side after cutting to the right and leave a certain amount of reserved slack during pulling. The control of the reserved slack is controlled by the degree of extension and contraction of the clamping, pulling and guiding mechanism. The purpose of reserving a certain amount of slack is to facilitate the completion of molding and adsorption on the corresponding arc-shaped inner surface 12 and shaping during negative pressure adsorption.

In any of the above schemes, it is preferred that the pushing and discharging mechanism includes a multi-stage telescopic pushing cylinder 22 horizontally fixedly installed at the corresponding position of the rear baffle 4, and a pushing plate 23 is fixedly installed at the end of the piston rod of the multi-stage telescopic pushing cylinder 22. In the working state, the pushing plate 23 extends from the back to the front to the space between the two clamping and wrapping mechanisms and pushes the rolled plastic film hand roll 3 with the outer surface packaged forward and then falls on the belt conveyor equipment 5 and continues to be transported to the downstream end sealing process.

When the pushing and discharging mechanism works, it mainly relies on the extension of the multi-stage telescopic pushing cylinder 22 to drive the pushing plate 23 at its end to continuously approach the packaged plastic film hand roll 3 inside the packaging space, and then pushes the plastic film hand roll 3 out of the packaging space between the two clamping and covering mechanisms through the forward thrust, and then makes it fall on the belt conveyor 5 for collection and transfer to the downstream process.

In any of the above schemes, it is preferred that the packaging film unwinding mechanism 2 includes side panel seats 24 that are relatively spaced apart along the front-to-back direction in the internal space of the side-opening box 1, the ends of each of the side panel seats 24 are fixedly arranged, and a reel body 25 is arranged between the two side panel seats 24, and both ends of the central axis of the reel body 25 are movable through the through holes on the corresponding side panel seats 24, and a servo reel motor 26 is fixedly installed on the front side of the side panel seat 24, and the motor shaft of the servo reel motor 26 is fixedly connected to the central axis of the reel body 25, and a rolled outer packaging film 6 is wound on the reel body 25, and the unwinding end of the outer packaging film 6 is extended and wound on the auxiliary reversing roller 21 on the corresponding side.

The packaging film unwinding mechanism 2 relies on the servo reel motor 26 to drive the rolled outer packaging film 6 thereon to unwind as needed. When unwinding, it cooperates with the traction action of the clamping, pulling and guiding mechanism to achieve appropriate synchronization of unwinding and traction, ensuring the mutual coordination and smoothness of the actions. After unwinding is in place, the servo reel motor 26 is braked, and at the same time, the two main reversing rollers 19 can be used to clamp the outer packaging film 6, thereby separating the packaging films on both sides thereof.

In any of the above schemes, it is preferred that the clamping, pulling and guiding mechanism includes a multi-stage traction telescopic cylinder 27 fixedly mounted on the right inner wall of the internal space of the side-opening box 1, and a clamping traction device 28 is fixedly mounted on the left end of the piston rod of the multi-stage traction telescopic cylinder 27.

In any of the above schemes, it is preferred that the clamping and traction device 28 includes a U-shaped traction seat 2801 fixedly mounted on the left end of the piston rod of the multi-stage traction and telescopic cylinder 27, and a clamping cylinder 2803 is arranged at intervals from top to bottom in the U-shaped opening 2802 of the U-shaped traction seat 2801, and a clamping guide plate 2804 is fixedly mounted on the inner end of the piston rod of each clamping cylinder 2803, and both ends of each clamping guide plate 2804 are tilted upward to form a guide section 2805. Under the action of the clamping cylinder 2803, the two clamping guide plates 2804 can clamp the right end of the two layers of outer packaging film 6 on the left side and pull it to the right side.

When the clamping and pulling guiding mechanism is working, it relies on the multi-stage traction telescopic cylinder 27 with a multi-stage telescopic function to control its overall extension length to the left or right. Before extending to the left, the clamping cylinders 2803 on both sides are controlled to return, so that the two clamping guide plates 2804 are in the largest opening state. After extending to the left in place, the two clamping cylinders 2803 are controlled to extend relatively and rely on two clamping guide plates 2804 close to each other to clamp the right ends of the two layers of outer packaging film 6 entering the U-shaped opening 2802 of the U-shaped traction seat 2801, and then the entire multi-stage traction telescopic cylinder 27 is controlled to be pulled to the right. The length of the multi-stage traction telescopic cylinder 27 returning to the right can control the length of the outer packaging film 6 being pulled. When pulled to an appropriate length, it is kept in position. Then, after the correspondingly configured detection switch detects that it is in place, the clamping and coating mechanisms are controlled to approach each other. While approaching, the negative pressure generator 8 is kept started and turned to an appropriate gear to ensure that the outer packaging film 6 can be quickly adsorbed and formed after it is in place. After adsorption and forming, the current series of actions of thermal synthesis and cutting are performed again.

Specific working principle: This automated intelligent packaging equipment can complete the rapid packaging of cylindrical curved surfaces for cylindrical rolled biodegradable plastic film hand rolls 3. During packaging, the upper and lower packaging film unwinding mechanisms 2 can be used to unwind synchronously to achieve rapid delivery of the outer packaging film 6 required for packaging. The outer packaging film 6 is pulled into place by the clamping, pulling and guiding mechanism during transportation. After it is in place, the two layers of adsorbed outer packaging film segments are respectively adsorbed on the arc-shaped inner surface 12 of the arc-shaped shaping seat 10 through counter-pressure and two-way negative pressure adsorption by the counter-pressure automatic packaging component to maintain positioning and forming. At this time, a cylindrical packaging space for the rolled plastic film hand roll 3 to enter will be formed in the middle of the two layers of outer packaging film segments. The hot pressing process is started by starting the heat sealing and cutting unit. During the hot pressing, the two layers of outer packaging film segments on both sides of the plastic film hand roll 3 can be heat-sealed within a certain length range by reciprocating small-amplitude rotation. Because the outer packaging film 6 has a certain ductility, the width range of the heat-sealed part will be increased, the firmness of the heat-sealed bonding will be ensured, and the probability of opening will be reduced.

After the heat sealing is completed, the heat sealing and cutting unit can be controlled to rotate to a set angle. At this time, the cutting process inside the heat sealing and cutting unit is started to complete the oblique cutting of the outer packaging films 6 on both sides outside the heat sealing area. Since the outer packaging film 6 is in a tensioned state and the cutting knife 17 is preheated by electric heating, the cutting effect can be guaranteed during cutting.

After cutting, the outer packaging film 6 is wrapped around the plastic film hand roll 3 and is completely separated from the outer packaging film 6 as a whole. At this time, after receiving the cutting completion signal, the external existing controller can control the material pushing and discharging mechanism to work and push the material pushing and discharging mechanism outward and drop it onto the matching belt conveyor 5 to be transported to the downstream end sealing process. In addition, in order to ensure the smoothness of pushing, the plastic film hand roll 3 clamped by the two is in a relaxed and free state by controlling the relative distance of the clamping and covering mechanism before the material pushing and discharging mechanism works. Therefore, the smoothness of pushing can be guaranteed when pushing outward in this state.

In summary, it can be seen that the present automated intelligent packaging equipment can realize the packaging of the cylindrical outer surface of the rolled plastic film hand roll 3 when packaging it, and the overall packaging efficiency is relatively high. The double-sided laying combined with hot pressing and heat sealing method can realize the rapid heat sealing and fast cutting of the connecting parts on both sides, and the external feeding equipment can realize the rapid feeding of the rolled plastic film hand roll 3. The present invention adopts a clamping and pulling guiding mechanism to quickly pull the two layers of outer packaging film 6 guided by the packaging film unwinding mechanism 2 and reserve a certain slack length, which is convenient for cooperating with the starting clamping and covering mechanism to respectively pull the two layers of outer packaging film 6. The packaging film 6 is negatively pressured and shaped in the opposite direction to form a nearly cylindrical space for the rolled plastic film hand roll 3 to be packaged to enter, and the two layers of outer packaging film 6 on the upper and lower sides are effectively used to achieve covering packaging. The overall packaging method is different from the traditional packaging method. When the rolled plastic film hand roll 3 entering the packaging position is sealed on both sides, the heat sealing and cutting unit can be used to perform a linkage operation of heat sealing first and then cutting. At the same time, after the cutting is completed, the packaged rolled product can be quickly pushed out by the pushing and discharging mechanism and fall on the belt conveyor 5 to be transported to the downstream end sealing process, thereby ensuring the smoothness of the entire packaging process.
