Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] To address the issue of high labor intensity in existing tobacco leaf stitching techniques, which require operators to manually press one end of the tobacco leaf with a pressure bar, this solution provides a tobacco stitching mechanism that can press and transport the tobacco leaves, ensuring stitching during transport. Please see Figures 1-4 , Figures 1-4 A tobacco weaving mechanism according to one embodiment of the present invention includes a workbench 1, a traction mechanism 2, and a stitching mechanism 3. The workbench 1 has a stitching area 1a. The traction mechanism 2 includes a conveying component 21, a lifting component 22, and a pressing component 23. The conveying component 21 and the lifting component 22 are both installed on the workbench 1. The pressing component 23 is connected to the lifting component 22. An adjustable transmission gap 2a is formed between the rotating parts of the conveying component 21 and the pressing component 23. When the tobacco leaves are arranged in the transmission gap and one end extends into the stitching area 1a, the rotating parts of the conveying component 21 and the lifting component 22 can cooperate to press the tobacco leaves and drive the tobacco leaves to move in a preset direction. The stitching mechanism 3 is installed on the workbench 1 and located at one end of the stitching area 1a. It is used to stitch the moving tobacco leaves.

[0019] In actual use, multiple tobacco leaves are placed side by side in the transmission gap 2a, ensuring that one end of the tobacco leaves extends into the seam-seam area 1a. The lifting member 22 drives the pressing member 23 to move to adjust the size of the transmission gap, so that the tobacco leaves are pressed tightly in the transmission gap 2a. The moving parts of the conveying member 21 and the pressing member 23 can rotate to drive the tobacco leaves to move, and the seam-seam mechanism 3 can then seam the moving tobacco leaves.

[0020] It should be noted that the conveying component 21 and the extrusion component 23 are not limited to a specific structure. In one embodiment, the conveying component 21 includes two rotating rollers 211, a conveyor belt 212, and a drive motor 213. The two rotating rollers 211 are rotatably mounted on the worktable 1, the conveyor belt 212 is connected between the two rotating rollers 211, and the drive motor 213 is mounted on the worktable 1 with its output end connected to one of the rotating rollers 211. The extrusion component 23 includes a base 231, two idler rollers 232, an extrusion belt 233, and a servo motor 234. The base 231 is connected to the lifting component 22, both idler rollers 232 are rotatably mounted on the base 231, the extrusion belt 233 is connected between the two idler rollers 232, the servo motor 234 is mounted on the base 231 and connected to one of the idler rollers 232, and a transmission gap is formed between the extrusion belt 233 and the conveyor belt 212.

[0021] It is understandable that by driving a rotating roller 211 to rotate via a drive motor 213, the conveyor belt 212 is driven to rotate. At the same time, by driving a roller 232 to rotate via a servo motor 234, the extrusion belt 233 is driven to rotate, pressing the tobacco leaves between the conveyor belt 212 and the extrusion belt 233. This can make the tobacco leaf layer thickness uniform, reduce the gaps, and prevent the leaves from loosening during subsequent stitching.

[0022] In addition, based on the above scheme, in order to ensure that the tobacco leaves are arranged at relatively uniform intervals, in one embodiment, the outer side of the conveyor belt 212 is provided with a plurality of spacers 2121 at intervals, and the spacers 2121 are arranged along the direction perpendicular to the movement of the tobacco leaves.

[0023] Specifically, a placement space is formed between two adjacent partitions 2121, and the operator can place one or two tobacco leaves in each placement space to ensure that the tobacco leaves are arranged relatively evenly.

[0024] It should be noted that, in order to ensure that the conveyor belt 212 and the compression belt 233 can compress the tobacco leaves when they are placed in the placement space, the height of the partition 2121 should not be set too high. The height of the partition 2121 is 2-3 cm, preferably 2 cm.

[0025] It should be noted that the lifting component 22 is not limited to a specific structure. The lifting component 22 includes a frame 221 and a telescopic part 222. The frame 221 is installed on the workbench 1, and the telescopic part 222 is installed on the frame 221. The telescopic part 222 is connected to the seat 231 and can drive the seat 231 to move up and down.

[0026] In this specific embodiment, there are two lifting components 22, which are respectively located at opposite ends of the worktable. The two lifting components 22 are connected to the seat 231, which can improve the stability of the seat 231 during the lifting process.

[0027] In one embodiment, the telescopic part 222 is an electric cylinder. Of course, in other embodiments, the telescopic part 222 can also be a pneumatic cylinder or a hydraulic cylinder.

[0028] When there are two lifting components 22, both electric cylinders are electrically connected to the controller, and the controller controls the electric cylinders to start and stop simultaneously. In addition, the controller is also electrically connected to the drive motor 213 and the servo motor 234 respectively, and the controller can control the drive motor 213 and the servo motor 234 to start and stop simultaneously.

[0029] It should be noted that the stitching mechanism 3 is not limited to a specific type of mechanism; it can be used to stitch any movable tobacco leaves. No other limitations are imposed here. Preferably, the stitching mechanism 3 can be the switch structure of a sewing machine and the sewing machine disclosed in the existing patent document CN211571003U.

[0030] In addition, based on the above scheme, in order to ensure that the length of the tobacco leaf extending into the seam area 1a is the same, a positioning plate 4 is specifically included. The positioning plate 4 is installed on the workbench 1 and extends along the moving direction of the tobacco leaf and is located in the seam area 1a.

[0031] It is understandable that when the tobacco leaf is placed in the transmission gap 2a, one end of the tobacco leaf extends into the seam area 1a and abuts against the positioning plate 4, which can ensure that the length of the tobacco leaf extending into the seam area 1a is the same.

[0032] It should be noted that, in one embodiment, the width of the extrusion belt 233 is 1 / 3 to 2 / 5 of the width of the conveyor belt 212, wherein both the conveyor belt 212 and the extrusion belt 233 are rubber tracks.

[0033] Furthermore, based on the above scheme, in order to facilitate the movement of the worktable 1, specifically, the bottom of the worktable 1 is provided with multiple rolling elements 11; it should be noted that the rolling elements 11 are moving rollers, and at least one of the rolling elements 11 has a braking function.

[0034] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
