The heating and humidifying are important processes of the cigarette shred production line. The heating and humidifying machine is key equipment for heating and humidifying tobacco material, and has the working principle that during the tobacco material conveying process, a great amount of saturated steam is applied to the tobacco material to heat, humidify and expand the tobacco material, and the tobacco material is conveyed to the downstream cut tobacco drier for fast drying.

In order to improve the work flexibility of heating humidifier, improve heating humidifier's product adaptability, this application provides a heating humidifier.

Fig. 1 to 3 show an exemplary structure of the warming and humidifying machine of the present application.

For ease of understanding, the basic structure of the warming and humidifying machine will be described first with reference to fig. 1.

Referring to fig. 1, a warming and humidifying machine 10 generally includes an infeed conveyor 1, a steam injection mechanism 2, and an outfeed conveyor 3. Typically, tobacco material (e.g., cut tobacco) flows through the feeding conveyor 1, the steam injection mechanism 2 and the discharging conveyor 3 in sequence, that is, the feeding conveyor 1, the steam injection mechanism 2 and the discharging conveyor 3 are arranged in sequence along the flowing direction of the tobacco material. Wherein, the steam injection mechanism 2 is used for injecting steam to the tobacco material so as to realize the warming and humidifying of the tobacco material. The feeding conveyor 1 is connected with the steam injection mechanism 2 and is used for conveying the tobacco material to the steam injection mechanism 2. The discharging conveyor 3 is connected with the steam injection mechanism 2 and is used for discharging the tobacco materials which are heated and humidified by the steam injection mechanism 2.

In the related art, the material conveyed by the feeding conveyor 1 can only flow to the discharging conveyor 3 through the steam injection mechanism 2, that is, all the tobacco material entering the warming and humidifying machine must flow through the steam injection mechanism 2, which can well meet the requirement of the product requiring steam warming and humidifying but is difficult to effectively meet the requirement of the product requiring no steam warming and humidifying.

Along with the improvement of the processing technology level of the tobacco shreds, the processing technology of the tobacco shreds with different production grades has differences. Currently, some grades require steam warming and humidifying, while other grades do not.

Based on the temperature-increasing and humidifying machine in the related technology, even if the material which is not required to be heated and humidified by steam flows through the steam injection mechanism 2, the material can reach the discharging conveyor 3, the whole process is long, and the production efficiency is influenced. Moreover, for a common Sirox temperature-increasing humidifier, the material which does not need to be heated and humidified by steam flows through the steam injection mechanism 2, and the problems of increased shredding rate, blockage of spray holes and the like are caused.

In the Sirox temperature-increasing humidifier, the steam injection mechanism 2 injects steam toward the tobacco material through the rotating roller 21. The roller 21 is rotatably provided and includes a roller body and raker nails. The harrow nails are arranged on the roller body and rotate along with the roller body. The harrow nails are provided with spray holes, and steam is sprayed to the tobacco material through the harrow nails.

In the related art, in order to meet the process requirements of materials which do not need to be steamed, the corresponding materials are not steamed, and the Sirox temperature-increasing humidifier only enables the rotating roller 21 to idle and does not inject steam when the corresponding materials flow through the steam injection mechanism 2. However, since the rotary roller 21 rotates, when the material to which steam is not applied passes through the idle rotary roller 21, crumbling occurs, resulting in an increase in the rate of finished cut tobacco. Moreover, as the rotary roller 21 does not apply steam, the tobacco powder is easy to enter the spray holes on the harrow nails when the material passes through, so that the spray holes are blocked, and the normal steam spraying effect is influenced.

It can be seen that, only via the humidification machine that heats of the single channel of steam injection mechanism 2 to 3 transported substance material of ejection of compact conveyer, the work flexibility is relatively poor, and product adaptability is relatively weak, is difficult to effectively satisfy the production demand that need not to apply the material of steam, not only influences the production efficiency that need not to apply the steam material, causes shredded rate increase and orifice blockage scheduling problem easily moreover.

In view of the above, the present application improves the structure of a warming and humidifying machine. The corresponding improvements will be described next in conjunction with fig. 1-3.

Referring to fig. 1, in the present application, an opening 11 and a cover plate 12 are provided on an infeed conveyor 1 of a warming humidifier 10, and the warming humidifier 10 includes a material guide 13. The cover 12 is movably disposed at the opening 11, and controls opening and closing of the opening 11 by moving between an open position and a closed position. The material guide member 13 connects the opening 11 and the discharging conveyor 3, and guides the flow of the tobacco material on the feeding conveyor 1 to the discharging conveyor 3 when the opening 11 is controlled to be opened by the cover plate 12.

Based on the opening 11, the cover plate 12 and the material guiding member 13, the temperature-increasing humidifier 10 can not only convey materials to the discharging conveyor 3 through the steam injection mechanism 2, but also convey materials to the discharging conveyor 3 through the opening 11 and the material guiding member 13, so that the temperature-increasing humidifier 10 is not a single-channel structure, but is a double-channel structure, and has a conventional conveying channel of the feeding conveyor 1, the steam injection mechanism 2 and the discharging conveyor 3, and also has a bypass conveying channel of the feeding conveyor 1, the opening 11, the material guiding member 13 and the discharging conveyor 3.

When the brand needing steam application is produced, the cover plate 12 is not opened, and the opening 11 is kept closed, so that the tobacco materials can still normally flow from the feeding conveyor 1 to the steam injection mechanism 2, and flow to the discharging conveyor 3 after steam heating and humidifying are carried out at the steam injection mechanism 2, and a conventional production mode based on a conventional conveying channel of the feeding conveyor 1, the steam injection mechanism 2 and the discharging conveyor 3 is completed.

When the brand which does not need to be applied with steam is produced, the cover plate 12 can be controlled to act, the opening 11 is opened, the feeding conveyor 1 is communicated with the material guiding part 13 through the opening 11, so that the material on the feeding conveyor 1 can directly fall to the material guiding part 13 through the opening 11 before flowing to the steam injection mechanism 2 and fall to the discharging conveyor 3 through the material guiding part 13, and a bypass production mode based on a bypass conveying channel of the feeding conveyor 1, the opening 11, the material guiding part 13 and the discharging conveyor 3 is completed.

In the bypass production mode, materials which do not need to be subjected to steam do not need to flow through the steam injection mechanism 2, but can directly fall onto the discharging conveyor 3 through the material guide piece 13, and the flowing path is shortened, so that the production efficiency of products of corresponding brands is improved. Moreover, when the steam injection mechanism 2 comprises the rotating roller 21, since the material which does not need to be applied with steam can be prevented from flowing through the idle rotating roller 21, the material is prevented from being crushed and blocked by the spray holes on the rotating roller 21, the shredding rate of the finished cut tobacco is reduced, and the normal production of the brand which needs to be applied with steam is prevented.

It can be seen that the opening 11, the cover plate 12 and the material guide member 13 are additionally arranged in the heating and humidifying machine 10 to switch between the conventional production mode and the bypass production mode, so that the working flexibility of the heating and humidifying machine 10 can be effectively improved, the adaptability of the heating and humidifying machine 10 to products can be enhanced, and the production requirement of materials without steam can be better met on the premise of not influencing the original functions of equipment.

The movement of the cover 12 between the open position and the closed position may be various, and may be either moving or rotating, or a combination of moving and rotating. For example, referring to fig. 2 and 3, in some embodiments, a cover 12 is rotatably coupled to the infeed conveyor 1 to control opening and closing of the opening 11 by rotating between an open position and a closed position. At this time, the cover plate 12 is rotated to open and close the opening 11, so that the structure is simple and the control is convenient.

Additionally, referring to fig. 3, in some embodiments, the warming humidifier 10 includes a drive mechanism 4, the drive mechanism 4 being drivingly connected to the cover 12 for driving the cover 12 between the open and closed positions. Based on this, can drive apron 12 automatic between open position and closed position and move, realize the automatic switching of normal mode of production and bypass production mode, it is more efficient.

By way of example, referring to fig. 3, the drive mechanism 4 includes a drive cylinder 41, the drive cylinder 41 being drivingly connected to the lid 12 for driving the lid 12 between the open and closed positions. At this moment, the structure is simpler, and control is more convenient.

The driving cylinder 41 may be a hydraulic cylinder, an air cylinder or an electric cylinder.

When the driving cylinder 41 is a hydraulic or pneumatic cylinder, see fig. 3, in some embodiments the driving mechanism 4 comprises not only the driving cylinder 41, but also a connecting pipe 42 and a control valve 43. The connecting pipe 42 is connected with the driving cylinder 41, the control valve 43 is arranged on the connecting pipe 42, and the driving cylinder 41 is controlled to drive the cover plate 12 to rotate between the opening position and the closing position by controlling the connecting pipe 42 to alternately introduce pressure medium (such as oil or gas) into one of the rod chamber 411 and the rodless chamber 412 of the driving cylinder 41. Therefore, the cover plate 12 can be controlled to be switched between the opening position and the closing position only by controlling the control valve 43 to switch the valve position, so that the bypass conveying channel is opened or closed, and the method is simple and convenient.

Specifically, in some embodiments, the control valve 43 is a solenoid valve, which facilitates control. For example, referring to fig. 3, in some embodiments, the warming humidifier 10 includes a controller 5, and the controller 5 is in signal connection with a control valve 43, which is a solenoid valve, to control the connecting pipe 42 to alternately introduce the pressure medium into one of the rod chamber 411 and the rodless chamber 412 of the driving cylinder 41 by controlling the control valve 43 to switch the valve position, thereby controlling the warming humidifier 10 to switch between the normal production mode and the bypass production mode.

The embodiments shown in fig. 1-3 will be further described below.

As shown in fig. 1 to 3, in this embodiment, the warming and humidifying machine 10 is a Sirox warming and humidifying machine, and the vapor injection mechanism 2 thereof includes a rotating roller 21, and an inlet conveyor 1 and an outlet conveyor 3 are respectively arranged upstream and downstream of the rotating roller 21.

In this embodiment, both the in-feed conveyor 1 and the out-feed conveyor 3 are vibrating conveyors. As can be seen from fig. 2, the discharge conveyor 3 is located below the feed conveyor 1 in the height direction. Note that the steam injection mechanism 2 is not shown in fig. 2 because the steam injection mechanism 2 is arranged at an angle to the feed conveyor 1, and specifically, in fig. 2, the steam injection mechanism 2 is located inside the paper surface, and is hidden from view.

In order to improve the operational flexibility and product adaptability of the warming-up humidifier 10, as shown in fig. 2 and 3, in this embodiment, an opening 11 is provided at the bottom of the conveying passage of the feed conveyor 1, and a cover plate 12 rotatably connected to the feed conveyor 1 is provided at the opening 11, and the cover plate 12 is connected to the cylinder rod of the driving cylinder 41. The driving cylinder 41 is a cylinder, and the rod chamber 411 and the rodless chamber 412 of the cylinder are respectively connected with the two working valve ports of the control valve 43 through the connecting pipe 42. The control valve 43 is a two-position four-way solenoid valve. When the two valve positions of the control valve 43 are switched, the two working valve ports are switched to communicate with the air source, so as to control the pressure air to flow into the rod chamber 411 and the rodless chamber 412 of the driving cylinder 41 in a switching manner, control the driving cylinder 41 to extend and retract, further drive the cover plate 12 to rotate between the opening position and the closing position, and control the opening 11 to be opened or closed.

As can be seen from fig. 3, in this embodiment, the control end of the control valve 43 is electrically connected to the controller 5 of the warming humidifier 10, so that the valve position is switched and the control opening 11 is opened or closed under the control of the controller 5.

In this embodiment, the controller 5, the driving cylinder 41, the connecting pipe 42 and the control valve 43 are all disposed near the cover plate 12 for easy operation and wiring.

Returning to fig. 2, in this embodiment, the opening 11 is connected to the output conveyor 3 through the material guiding member 13, so that when the opening 11 is opened, the material guiding member 13 communicates the input conveyor 1 and the output conveyor 3, and the bypass production mode is realized. The material guiding member 13 is located between the cover plate 12 and the discharging conveyor 3, and may be a material guiding pipe, a material guiding cover, a material guiding chute, or other various components capable of guiding the material to flow.

The warming humidifier 10 of this embodiment can be flexibly switched between the normal production mode and the bypass production mode.

When the brand of steam is required to be produced and applied, the driving cylinder 41 drives the cover plate 12 to be kept at the closed position, so that the material flows through a conventional conveying channel of the feeding conveyor 1, the steam injection mechanism 2 and the discharging conveyor 3 to be heated and humidified by steam, and a conventional production mode is completed.

When the brand without steam is required to be produced, the driving cylinder 41 drives the cover plate 12 to rotate from the open position to the open position, so that the material flows through a bypass conveying channel of the feeding conveyor 1, the opening 11, the guide member 13 and the discharging conveyor 3, directly slides into the discharging conveyor 3 through the guide member 13 without passing through the rotating roller 21 of the steam injection mechanism 2, and the bypass production mode is completed.

It can be seen that the heating and humidifying machine 10 of the embodiment has a simple structure and is flexible in operation, and can better meet the process requirement of the brand without applying steam on the basis of not influencing the normal steam spraying function, and prevent the material without applying steam from flowing through the rotating roller 21 to cause the increase of the broken filament rate or the blockage of the spray holes.

Additionally, the present application also provides a tobacco production system comprising the warming and humidifying machine 10 of any embodiment of the present application. In addition to including the warming and humidifying machine 10, the tobacco production system may also include a cut-tobacco drier.

The above description is only exemplary of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements and the like that are made within the spirit and principle of the present application should be included in the protection scope of the present application.
