And (3) after molding and curing, obtaining a prefabricated plate 300, and then, after post-curing treatment of a post-curing furnace 9 and subsequent air cooling treatment, rolling by a rolling machine 12 under the traction of a traction machine 10, thus obtaining a carbon fiber pultrusion plate finished product. The cutting machine 11 is arranged between the tractor 10 and the winding machine 12, and when the winding reaches a set length, the cutting machine 11 cuts the sheet material, so that the carbon fiber pultruded sheet material with the required specification can be obtained.

In detail, the yarn distributor 3 comprises a plurality of yarn collecting plates which are arranged in a vertically staggered mode, and carbon fibers penetrate through the yarn feeding holes 13 on each yarn collecting plate to collect yarns. The temperature control resin impregnation tank 5 is provided with a temperature control system for maintaining the resin impregnation material therein within a certain temperature range, thereby ensuring good impregnation effect.

In this embodiment, the straightness control device for a pultruded panel specifically includes a die area 100 and a straightness control area 200. In the above production equipment, the area where the forming mold 8 is located is the mold area 100, and the straightness control area 200 described in the embodiment is located after the forming mold 8 and before the tractor 10.

Further, a molding die 8 and a die adjusting assembly 110 are provided inside the die section 100. The forming die 8 is provided with an inlet 101 and an outlet 102, wherein the fiber after the dipping extrusion treatment enters the forming die 8 from the inlet 101 of the forming die 8, and after the prefabricated plate 300 is formed and formed, the prefabricated plate 300 is output from the outlet 102 of the forming die 8. The die adjusting assembly 110 is used for adjusting the position of the forming die 8 along the direction perpendicular to the fiber moving path, so that the direction of outputting the prefabricated plate 300 from the forming die 8 is basically coincident with the extending direction of the straightness control area 200, and further, the straightness of the prefabricated plate 300 after further curing is ensured. Referring to fig. 3, the fiber moving path is parallel to the left-right direction in the drawing, and the die adjusting unit 110 adjusts the position of the forming die 8 in the up-down direction in fig. 3.

The straightness control area 200 is internally provided with a straightness adjustment assembly, and the straightness adjustment assembly is arranged in contact with the prefabricated plate 300 of the output forming die 8 on at least one side of the fiber moving path. The straightness adjusting assembly can adjust the position of the prefabricated plate 300 along the direction perpendicular to the fiber moving path, so that the phenomenon that the prefabricated plate 300 is locally bent to cause the reduction of the straightness of the finished product of the carbon fiber pultruded plate is avoided.

In the above-described aspect, the mold adjusting unit 110 disposed in the mold area 100 can adjust the position of the forming mold 8, and the straightness adjusting unit disposed in the straightness control area 200 can adjust the position of the formed prefabricated sheet 300. In the production process of the pultruded plate, the two components are matched to realize more flexible adjustment operation, so that the straightness of the pultruded plate is controlled to be maintained at a stable level. As the on-line adjustment of the straightness of the plate in the production process is realized, the waste of raw materials can be reduced, and meanwhile, the straightness qualification rate of the finished product of the pultruded plate is obviously improved.

In a further aspect of this embodiment, the forming die 8 is disposed along the fiber moving path, and the inlet 101 thereof is disposed at an end of the forming die 8 away from the straightness control area 200 (i.e., the left end in fig. 3), and the outlet 102 is disposed at an end of the forming die 8 near the straightness control area 200 (i.e., the right end in fig. 3). Within the mold area 100, a mold adjustment assembly 110 is provided in a region proximate to an inlet 101 of the forming mold 8 and a region proximate to an outlet 102 of the forming mold 8, respectively.

Preferably, the die adjusting assemblies 110 are arranged in four groups, wherein two groups of die adjusting assemblies 110 are symmetrically arranged near the inlet 101 of the forming die 8 relative to the fiber moving path, and the other two groups of die adjusting assemblies 110 are symmetrically arranged near the outlet 102 of the forming die 8 relative to the fiber moving path.

Through the structure, the positions close to the two ends of the forming die 8 can be adjusted, the extending direction of the forming die 8 is controlled integrally, the situation that the forming die 8 deflects is effectively avoided, the moving direction in the plate forming process can be controlled better, and the prefabricated plate 300 can keep good straightness.

Further, the mold adjusting assembly 110 specifically includes a fixed block 111, an adjusting member 112, and a locking member 113. Wherein the fixed block 111 is fixedly installed in the mold area 100, the regulating member 112 is movably installed on the fixed block 111 in a direction perpendicular to the fiber moving path, and the regulating member 112 is stopped against the side surface of the molding mold 8. The locking member 113 is connected to the adjusting member 112 for fixing the position of the adjusting member 112 with respect to the fixing block 111.

In detail, the adjusting member 112 in this embodiment is a bolt, and the locking member 113 is a nut sleeved on the bolt. The fixing block 111 is internally provided with a screw hole through which a bolt passes, and the tip ends are stopped against the side surface of the molding die 8. By rotating the bolt as the adjusting member 112, the distance by which the bolt protrudes from the side of the fixing block 111 close to the molding die 8 can be adjusted, and further, the position adjustment is achieved by stopping the end of the bolt against the molding die 8. When the bolt is adjusted to a proper position, the nut serving as the locking piece 113 is screwed again to stop against the surface of one side of the fixed block 111 away from the forming die 8, so that the relative position of the bolt and the fixed block 111 can be fixed, and obvious displacement of the forming die 8 in the production process of the pultruded panel is effectively prevented.

In this embodiment, a heating assembly 120 for heating the molding die 8 is also provided in the die region 100. Specifically, the heating member 120 is a mold heating plate 7 that covers the surface of the molding die 8, extends along the fiber movement path to cover the molding die 8, and forms a covered area.

In detail, the mold heating plates 7 are provided in plurality and are distributed along the fiber moving path to cover the molding dies 8, thereby achieving a uniform heating effect on the molding dies 8.

In this embodiment, the straightness control area 200 has a start end near the die area 100 and an end far from the die area 100, i.e., an area before the tractor 10. In a further aspect of this embodiment, the straightness adjustment assembly includes a board adjustment mechanism 210, and the board adjustment mechanism 210 is disposed near the end of the straightness control area 200.

In the above-described embodiment, the sheet adjusting mechanism 210 is provided at the end of the straightness control area 200, and adjusts the position of the portion of the prefabricated sheet 300 that is to enter the tractor 10. Particularly, the position of the prefabricated plate 300 leaving the straightness control area 200 can be controlled to be positioned on the same straight line with the position of the prefabricated plate 300 just formed, which is output by the outlet 102 of the forming die 8, by being matched with the die adjusting assembly 110 arranged near the outlet 102 of the forming die 8, so that the straightness of the plate can be controlled more effectively and kept stable.

Further, the plate adjusting mechanism 210 specifically includes a bracket 211, a carrier roller 212, and a column 213. Wherein a bracket 211 is fixedly installed at a region near the end within the straightness control area 200, and a carrier roller 212 is rotatably installed on the bracket 211 for supporting the prefabricated panel 300 from below. The columns 213 are provided in two, respectively located at both sides of the prefabricated panel 300. The upright 213 is movably installed on the bracket 211 in a direction perpendicular to the fiber moving path, and the side wall of the upright 213 contacts with the side edge of the prefabricated panel 300, thereby realizing a limit function on the prefabricated panel 300.

In the above scheme, when the prefabricated panel 300 is pulled by the tractor 10, if a trace of lateral swing exists, linearity deviation is caused, and two upright posts 213 are arranged at the front end of the tractor 10 to play a role in limiting and guiding the prefabricated panel 300, so that the lateral swing amplitude of the prefabricated panel 300 can be minimized.

In the embodiment of the present utility model, the rotation axis of the carrier roller 212 is along the horizontal direction and perpendicular to the fiber moving path, and the carrier roller 212 rolls along the lower surface of the prefabricated plate 300 during the moving process of the prefabricated plate 300 under the traction action of the tractor 10, so that the prefabricated plate 300 can be supported to be in a horizontal state, and excessive friction resistance generated on the lower surface of the prefabricated plate 300 is avoided. Idler rollers 212 are preferably mounted on brackets 211 in an adjustable manner up and down to adjust the height position of sheet preform 300 at the front end of tractor 10 to ensure that sheet preform 300 can enter tractor 10 smoothly.

The bracket 211 is provided with a guide groove extending perpendicular to the moving path of the fiber, and the lower part of the upright 213 is inserted into the guide groove to be slidable along the path defined by the guide groove. The lower end of the upright post 213 penetrates through the guide groove and is sleeved with a fastening screw 215, and the position of the upright post 213 can be fixed through the fastening screw 215. The prefabricated plate 300 is supported by the carrier rollers 212 and limited between the upright posts 213 on two sides, and the upright posts 213 play a role in limiting and guiding the prefabricated plate 300, so that the prefabricated plate 300 is prevented from obviously swinging to influence the straightness.

Preferably, a scale 214 is provided on the bracket 211 along the guide slot, and an operator can read the real-time position of the upright 213 according to the scale provided on the scale 214, so as to determine whether the upright 213 is displaced during the production process. When the upright post 213 is displaced, the adjustment can be performed in time, and the straightness of the plate is ensured to be stable.

In a further aspect of this embodiment, the straightness adjustment assembly further includes an on-line detection mechanism 220, for implementing straightness detection during the movement of the prefabricated sheet 300. The on-line detection mechanism 220 is disposed in the middle area of the straightness control area 200, so that the straightness on-line detection can be performed on the area of the prefabricated plate 300 between the outlet 102 of the forming die 8 and the plate adjustment mechanism 210, and the operator can monitor the straightness of the plate in real time.

The in-line detecting mechanism 220 of the present embodiment specifically includes a measuring member 221 installed in the middle region of the straightness control area 200, located at one side of the prefabricated panel 300, and extending a certain length along the fiber moving path. A certain distance exists between the measuring member 221 and the prefabricated panel 300.

In the process of producing the pultruded panel, an operator can determine whether the straightness of the prefabricated panel 300 is maintained at a good level by observing whether the distance between the side edge of the prefabricated panel 300 and the measuring piece 221 is maintained consistent along the moving direction of the panel, that is, whether the width of the gap between the prefabricated panel 300 and the measuring piece 221 is maintained consistent everywhere.

Further, the operator may also measure the distance between the measuring member 221 and the prefabricated panel 300 at different positions of the extending area, for example, using a feeler gauge to detect the distance between the two. The current straightness level of the prefabricated panel 300 can be calculated by measuring the distance offsets at different positions.

In the detailed scheme of the embodiment, the online detection mechanism 220 further includes an adjustment handle 222, and an operator can integrally move the measuring member 221 in a direction perpendicular to the fiber moving path by rotating the adjustment handle 222. The width of the carbon fiber pultruded panel produced in the embodiment is about 100-120 mm, and an operator can adjust the distance between the measuring piece 221 and the prefabricated panel 300 to a proper size according to the prefabricated panels 300 with different widths by operating the adjusting handle 222 to integrally move the measuring piece 221.

Further, the on-line detecting mechanism 220 further includes a fine adjusting component 223, where the fine adjusting component 223 is movably disposed relative to the measuring component 221, and part of the fine adjusting component extends out of a side edge of the measuring component 221, so as to contact with the moving prefabricated board 300 to achieve a limiting effect on the prefabricated board 300.

The fine adjustment members 223 are provided in plural at intervals along the length extending direction of the measuring member 221, and the minimum value of the distance between the prefabricated panel 300 and the measuring member 221 can be limited. Thus, the accuracy of the straightness online detection result can be controlled by adjusting the fine adjustment member 223.

When the production equipment of the embodiment is adopted for producing the carbon fiber pultrusion plate, the operation process is specifically as follows:

preparation: the carbon fiber is orderly placed on a creel 1 and sequentially passes through a frequency meter 2, a yarn distributor 3, a layering device 4, a temperature control resin dipping tank 5, a preforming tool 6, a forming die 8, a post-curing furnace 9 and a tractor 10; starting the tractor 10 to drive the carbon fibers to move, and sequentially carrying out yarn collection, yarn separation, gum dipping and heating forming treatment to obtain a prefabricated plate 300;

pre-adjusting: after the prefabricated plate 300 moves to the straightness control area 200, the height of the carrier roller 212 in the plate adjusting mechanism 210 is adjusted, so that the prefabricated plate 300 smoothly enters the tractor 10; then, the straightness detection is carried out on the prefabricated plate 300 in the straightness control area 200, the die adjusting assembly 110 and the plate adjusting mechanism 210 are adjusted according to the detection result until the straightness detected meets the requirement, and the graduation of the graduated scale 214 corresponding to the position of the current upright 213 on the bracket 211 is recorded;

and (3) production of finished products: fixing the die adjusting assembly 110 and the plate adjusting mechanism 210, cutting off the plate obtained before the pre-adjustment is completed by using the cutter 11, and winding the prefabricated plate 300 obtained later by using the winding machine 12; simultaneously, the cutting machine 11 is used for cutting when the rolled plate reaches a set length;

on-line detection and adjustment: in the above-mentioned production process of finished products, an operator observes whether the interval distance between the prefabricated panel 300 and the measuring piece 221 is kept substantially uniform within the length range of the measuring piece 221, and when the interval distances at different positions are obviously different, the panel adjusting mechanism 210 can be adjusted so that the straightness of the prefabricated panel 300 is restored to a qualified level; meanwhile, an operator can also compare whether the scale of the graduated scale 214 corresponding to the position of the upright post 213 in the plate adjusting mechanism 210 is changed, so as to monitor whether the tracking upright post 213 is displaced, and even if the adjustment is performed.

In the production equipment of the pultruded panel, the mold adjusting assembly 110 is arranged in the mold area 100 where the forming mold 8 is located, and is used for fixing the position of the forming mold 8 in the production process and matching with the straightness adjusting assembly arranged in the subsequent straightness control area 200, so that the formed prefabricated panel 300 can be subjected to straightness online detection and adjustment, and the straightness qualification rate of the finished product of the pultruded panel is effectively improved.

As shown in fig. 1 and 9, this embodiment is further defined as the first embodiment, and the online detection mechanism 220 further includes a flat ruler 224 disposed between the measuring member 221 and the prefabricated panel 300.

Specifically, in the present embodiment, when the flat rule 224 is in contact with the side edge of the prefabricated panel 300 and the prefabricated panel 300 is substantially adhered to the flat rule 224 within the extension range of the flat rule 224, the straightness of the prefabricated panel 300 can be determined by measuring the distance between the flat rule 224 and the measuring member 221 at different positions, and the measuring tool (for example, a feeler gauge) does not need to be in direct contact with the prefabricated panel 300.

Further, the flat rule 224 is in direct contact with the fine adjustment component 223 in the online detection mechanism 220, the flat rule 224 is limited by the fine adjustment component 223, and the relative position of the flat rule 224 and the measuring piece 221 is controlled, so that the accuracy of straightness detection is controlled. Meanwhile, the prefabricated plate 300 moves under the single-side limiting action of the flat ruler 224, so that the prefabricated plate 300 can be prevented from tilting or bending caused by micro transverse swinging of the prefabricated plate 300 at the front end of the tractor 10 to a certain extent, straightness deviation can be eliminated timely, and the quality of a pultruded plate finished product on the straightness detection index can be guaranteed.

In this embodiment, by adding the leveling rule 224, it is more convenient for an operator to intuitively observe the straightness condition of the prefabricated plate 300, and the prefabricated plate 300 is not directly contacted to cause the damage of the plate when the straightness is measured. Meanwhile, the leveling rod 224 can realize continuous limiting action on the prefabricated plate 300 within a certain length range, which is beneficial to timely eliminating straightness deviation generated by the prefabricated plate 300 in the production process.

The foregoing description is only illustrative of the preferred embodiment of the present utility model, and is not to be construed as limiting the utility model, but is to be construed as limiting the utility model to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the utility model, may be made by those skilled in the art without departing from the scope of the utility model.
