[0002] In the leaf processing stage of cigarette production, the rollers used for feeding the leaves need to be cleaned and maintained daily to ensure that the equipment is clean and the tobacco formula is intact. At the end of the maintenance, the wet tobacco leaves inside the rollers need to be discharged and collected. After the wet tobacco leaves fall into the vibrating trough through the roller outlet, they need to be manually retrieved and collected.

[0003] The existing method for collecting wet tobacco sheets involves manual collection. This requires observing the accumulation of wet tobacco sheets in the vibrating trough, and once a certain amount is reached, using a tool to scrape it out of the trough outlet. The wet tobacco sheets are then manually scooped into a storage bag. While this method completes the collection, the wet tobacco sheets are hot, posing a risk of burns. Furthermore, the manual operation is cumbersome, prone to spillage, and can contaminate the production environment. The manual collection process is also inefficient and slow, impacting the overall process progress.

[0027] According to the present invention, a wet tobacco sheet clamping device is provided, such as... Figures 1 to 3 As shown, the wet tobacco sheet clamping device is used to clamp material 22, such as wet tobacco sheet, and the wet tobacco sheet clamping device includes a pushing assembly, a clamping assembly and a connecting assembly.

[0028] In the following description, reference will be made to Figures 1 to 3 This section describes the detailed structure of the pushing assembly, clamping assembly, and connecting assembly of the wet tobacco sheet clamping device.

[0029] like Figures 1 to 3 As shown, in this embodiment, the pushing component is connected to the gripping component via a connecting component, enabling the gripping component to reciprocate in the gripping direction. The gripping direction can be, for example, [missing information]. Figure 1 and Figure 3 In the first direction S1, the pushing component can drive the gripping component to move along the first direction S1, thereby pushing the gripping component into the inside of the drum, so as to facilitate the subsequent gripping of material 22.

[0030] Furthermore, the clamping assembly may include a clamping cylinder 8, a clamping linkage, and clamping push plates 14. The clamping cylinder 8 is disposed on the connecting assembly, and the end of the clamping linkage is provided with two clamping push plates 14 facing each other. The clamping cylinder 8 drives the clamping push plates 14 to move towards each other or away from each other via the clamping linkage (i.e., Figure 1 and Figure 3 The second direction (S2) moves to grip the wet tobacco sheet.

[0031] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the clamping link may include a link joint 12 and two moving parts 11 symmetrically arranged on both sides of the link joint 12, and each moving part 11 is provided with a clamping push plate 14 at its end.

[0032] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the moving part 11 may include a first link arranged along the clamping direction (i.e., the first direction S1), a second link arranged along the clamping push plate 14 in a direction that moves closer to or further away from each other (i.e., the second direction S2), and a third link connecting the connecting assembly and the second link. The two ends of the second link are hinged to the link joint 12 and the first link, respectively, and the two ends of the third link are hinged to the connecting assembly and the second link, respectively. The end of the first link is provided with the clamping push plate 14. It should be noted that the first, second, and third links are all components whose positions can be changed. The phrase "arranged along the first direction S1 or the second direction S2" can be understood as... Figure 1 The first direction S1 and the second direction S2. Figure 1 and Figure 2 The diagram shown depicts the extended state of the moving part 11, with the two gripping push plates 14 moving away from each other. Figure 3 The diagram shows the retracted state of the moving part 11, where the two clamping push plates 14 move closer to each other to clamp the material. It should be noted that the materials of the first, second, and third connecting rods need to have high strength and hardness, as well as sufficient toughness, to ensure that they can smoothly drive the clamping plates to clamp the wet tobacco sheet.

[0033] Preferably, such as Figures 1 to 3 As shown, in this embodiment, there are multiple second links, which are spaced apart from each other at the link joint 12. A third link is hinged to a nearby second link. The multiple second links ensure stable movement, thereby stabilizing the gripping of the material 22.

[0034] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the pushing assembly may include a pushing motor 1 and a coupling 2, with the pushing motor 1 connected to the connecting assembly via the coupling 2. It should be noted that the pushing motor 1 can rotate in both directions, and its specifications and power should meet actual needs to ensure it can drive the clamping assembly to reciprocate.

[0035] Preferably, such as Figures 1 to 3 As shown, in the embodiment, the connecting assembly may include a lead screw and nut assembly, a support plate 7 and a slide rail assembly. The support plate 7 is able to reciprocate along the clamping direction (i.e., the first direction S1) via the slide rail assembly. The lead screw and nut assembly is disposed at the bottom of the support plate 7 and connected to the push motor 1 via the coupling 2.

[0036] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the connecting assembly may further include a bearing seat 10, which is disposed at the end of the connecting assembly. The lead screw and nut assembly may include a lead screw 3, one end of which is disposed in the bearing seat 10, and the other end of which is connected to the coupling 2. The lead screw and nut assembly may further include a nut 4. The push motor 1 drives the lead screw 3 to rotate through the coupling 2, thereby causing the nut 4 to change position, and the nut 4 drives the support plate 7 to change position together. The slide rail assembly may include a slide rail 5 and a slider 6. The slider 6 is disposed at the bottom of the support plate 7, and the slide rail 5 is disposed on the bearing frame 18 described below. Through the cooperation of the slide rail 5 and the slider 6, the movement of the support plate 7 is made more stable.

[0037] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the wet tobacco sheet clamping device may further include a support frame 18, which may have multiple storage layers 17 for placing items such as unused wet tobacco bags or miscellaneous bags. The pushing assembly, clamping assembly, and connecting assembly are all mounted on the support frame 18. The storage layers 17 can be configured in terms of size and specifications as needed, or have anti-slip strips added around them to meet actual storage requirements.

[0038] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the bottom of the support frame 18 is provided with movable casters 19. The support frame 18 can be formed into an approximately cuboid frame structure, with movable casters 19 provided at each of the four bottom corners of the cuboid. The movable casters 19 can also be equipped with wheel locking devices to facilitate the movement and locking of the device. The specifications, dimensions, and number of movable casters can also be selected according to actual needs.

[0039] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the clamping pusher 14 is equipped with a sensor for detecting the falling material 22. Preferably, the sensor may include a first sensor 15 and a second sensor 16 arranged vertically. The first sensor 15 and the second sensor 16 may be, for example, infrared sensors, and the installation position of the infrared sensors can be set according to specific actual conditions to meet the detection and clamping work of the wet tobacco sheet.

[0040] The assembly process of the wet tobacco sheet clamping device is as follows: A push motor 1 is fixed to the top of the support frame 18 via threaded connection or welding. A coupling 2 is externally connected to the push motor 1. One end of the lead screw 3 is connected to the coupling 2, and the other end is connected to the bearing of the bearing seat 10. The bearing seat 10 is located on the top of the support frame 18 via threaded connection or welding, and is installed at the same horizontal plane as the push motor 1. A slide rail 5 is fixed to the top of the support frame 18 via threaded connection or welding. The slide rail 5 is arranged parallel to the lead screw 3. A slider 6 is provided on the slide rail 5, and the slider 6 is fixedly connected to the support plate 7 via threaded connection. A nut 4 is installed on the lead screw 3 and is fixedly connected to the support plate 7 via threaded connection. A clamping cylinder 8 is fixed to the top of the support plate 7 via threaded connection or welding. A piston rod 9 is externally connected to the clamping cylinder 8, and a connecting rod joint 12 is fixed to the end of the piston rod 9 via threaded connection. Two moving parts 11 are respectively hinged to both sides of the connecting rod joint 12, and the hinges can be connected by bolts 13, allowing for rotation. A clamping push plate 14 is fixed to the end of the moving parts 11, and the installation direction of the clamping push plate 14 is relatively perpendicular to the support plate 7. Infrared sensors, namely a first sensor 15 and a second sensor 16, are installed one above the other at the middle position of the clamping push plate 14. A moving pulley 19 is provided at the bottom of the support frame 18. A switch, including a start button 20 and a stop button 21, can be provided on the top of the support frame 18, on the side of the pushing motor 1, to control the start and stop of the device.

[0041] The operation of this wet tobacco sheet clamping device is as follows: First, during the maintenance of the rollers, when it is necessary to clamp the wet tobacco sheet, push the device to a suitable position parallel to the vibrating groove 24. Figure 2As shown, pressing the start button 20 starts the device; secondly, the push motor 1 starts, driving the coupling 2 to rotate, which in turn drives the lead screw 3 to move, and the nut 4 moves under the drive of the lead screw 3, thereby driving the support plate 7 and the slider 6 to move on the slide rail 5; thirdly, after the support plate 7 moves to the appropriate position, the push motor 1 stops driving, and at this time the clamping cylinder 8 starts, driving the piston rod 9 to extend outward, driving the connecting rod of the moving part 11 to move, causing the clamping push plate 14 to open and move to the designated position of the vibration groove 24; fourthly, at this time, the clamping push plate 14 is installed on the clamping push plate 14. The first sensor 15 and the second sensor 16 are activated for detection. When material 22 falls into the vibrating groove 24 from the drum outlet 23, the second sensor 16 will detect that material 22 has fallen, and the clamping cylinder 8 will prepare for operation. In the fifth step, when material 22 falls into the vibrating groove 24 and reaches a certain height, the first sensor 15 detects that the wet tobacco sheet has reached the clamping height. At this time, the clamping cylinder 8 is driven again, causing the piston rod 9 to retract. The connecting rod joint 12 at the end of the piston rod 9 drives the multiple connecting rods of the moving part 11 to retract, thereby driving the clamping push plate 14 to complete the clamping action, and the material 22 is clamped. Figure 3 As shown; in the sixth step, after the material 22 is clamped, the push motor 1 starts again, and the reverse drive drives the support plate 7 to retract, bringing the clamping cylinder 8 and the clamping push plate 14 away from the vibration groove 24 together; in the seventh step, after the clamping push plate 14 leaves the vibration groove 24 to the designated position, the push motor 1 stops driving. At this time, the clamping cylinder 8 drives the piston rod 9 to extend outward. Under the drive of the connecting rod joint 12 and the moving part 11, the clamping push plate 14 is released, and the material 22 falls into the corresponding wet material bag, thus completing one automatic clamping operation of the tobacco wet material; in the eighth step, the above steps two to seven can be repeated according to the actual situation to continuously complete the clamping operation of the tobacco wet material. When the clamping operation is completed or it is necessary to stop the clamping operation, the device can be stopped by pressing the switch stop button 21.

[0042] This wet tobacco sheet clamping device, through the cooperation of a pushing component, a clamping component, and a connecting component, can achieve automated clamping of wet tobacco sheets, avoiding the risk of burns from manual clamping, and solving the problems of cumbersome manual operation and low production efficiency. Automated clamping can reduce labor consumption and labor costs, maintain a clean production environment to the maximum extent, increase the speed of roller maintenance, and improve work and production efficiency.
