[0020] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will combine the drawings in the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3, which is a schematic structural diagram of the automatic clamping mechanism of the cigarette clip provided by the present utility model. The automatic clamping mechanism of the cigarette clip includes a cigarette fork conveying component 31, a clip conveying component 33, and a clamping component 50. A horizontally arranged cigarette fork conveying channel 319 is formed on the cigarette fork conveying component 31, and a horizontally arranged clip conveying channel 339 is formed on the clip conveying component 33. A number of cigarette forks are placed on the cigarette fork conveying component 31 and conveyed to the clamping station through the cigarette fork conveying channel 319. At the same time, a number of clips are placed on the clip conveying component 33 and conveyed to the clamping station through the clip conveying channel 339. The clamping component 50 includes a pressing plate 55 arranged above the clamping station and a lower pushing plate 51 arranged below the clamping station. The pressing plate 55 moves downward and the lower pushing plate 51 pushes upward to clamp the cigarette forks and clips at the clamping station. By arranging the cigarette fork conveying component 31 and the clip conveying component 33, the cigarette forks and clips are automatically conveyed to the clamping station. After a number of cigarette forks and clips are placed on the cigarette fork conveyor belt 313 and the clip conveyor belt 333, they are automatically conveyed to the clamping station one by one in an orderly manner. Then, through the relative movement of the lower pushing plate 51 and the pressing plate 55 of the clamping component 50, the cigarette forks 40 and clips 60 at the clamping station are clamped. During the conveying process of the cigarette forks 40 and clips 60, there is no need for additional structures to change their movement states. They can be directly conveyed to the clamping station to achieve the clamping of the cigarette forks and clips. The processing actions are simplified, the automation of clamping is realized, and the work efficiency is greatly improved.

[0022] Specifically, in this embodiment, the cigarette fork conveying component 31 includes an upper driving member 311, two relatively spaced cigarette fork conveyor belts 313, upper guide plates 315 installed on each of the cigarette fork conveyor belts 313, and a cigarette fork bin 317 installed at the end of the cigarette fork conveyor belt 313. The two upper guide plates 315 are relatively spaced to form a cigarette fork movement channel 319. The cigarette forks are placed on the cigarette fork conveyor belt 313 and conveyed to the cigarette fork bin 317 through the cigarette fork movement channel 319. The upper driving member 311 drives the cigarette fork conveyor belt 313 to move in a cycle to convey the cigarette forks placed on the conveyor belt into the cigarette fork bin 317.

[0023] Furthermore, each of the cigarette fork conveyor belts 313 includes an upper positioning beam 3131, upper pulleys 3133 installed on the upper positioning beam 3131, and an upper transmission belt 3135 wound around the upper pulleys 3133. The upper guide plates 315 are installed on the upper positioning beam 3131 along the transportation direction of the upper transmission belt 3135. The upper driving member 311 is a motor. The motor shaft is connected to the upper pulley 3133 to drive the upper pulley 3133 to move. The upper pulley 3133 then drives the upper transmission belt 3135 wound around it to move in a cycle to convey the cigarette forks placed on the upper transmission belt 3135.

[0024] Further, the cross-section of the upper guide plate 315 is L-shaped. Two L-shaped upper guide plates 315 are arranged back to back to form a channel for conveying the cigarette fork and can limit the conveying position and angle of the cigarette fork.

[0025] Meanwhile, the clip conveying assembly 33 includes a lower driving member 331, two relatively spaced clip conveyor belts 333, lower guide plates 335 mounted on each of the clip conveyor belts 333, and clip bins 337 located at the ends of the clip conveyor belts 333. The two lower guide plates 335 are relatively spaced to form a clip moving channel 339. Clips are placed on the clip conveyor belts 333 and conveyed to the clip bins 337 through the clip moving channel 339.

[0026] Wherein, the clip conveyor belts 333 and the cigarette fork conveyor belts 313 have the same structure. Similarly, the clip conveyor belts 333 include lower positioning beams 3331, lower pulleys 3333 mounted on the lower positioning beams 3331, and lower transmission belts 3335 wound around the lower pulleys 3333. The lower guide plates 335 are mounted on the lower positioning beams 3331 along the transportation direction of the lower transmission belts 3335. The lower driving member 331 is a motor, and the motor shaft is connected to the lower pulley 3333 to drive the lower pulley 3333 to move, and the lower pulley 3333 then drives the lower transmission belt 3335 wound thereon to circulate and convey the clips placed on the lower transmission belt 3335. The two cigarette fork conveyor belts 313 are driven to move synchronously by an upper driving member 311. Similarly, the two clip conveyor belts 333 are driven to move synchronously by a lower driving member 331.

[0027] As Figure 4 shown, wherein, the cigarette fork bins 317 and the clip bins 337 are both blocks with an L-shaped cross-section. The blocks are vertically arranged, and an accommodating space for accommodating the cigarette fork and the clip is formed inside the L-shape of the block. The cigarette fork and the clip are respectively pushed from the cigarette fork conveyor belts 313 and the clip conveyor belts 333 into the accommodating space. This space is only a temporary storage position for the cigarette clip. After the previous cigarette clip is clamped, the next cigarette clip is pushed into this space.

[0028] Wherein, the lower guide plates 335 and the upper guide plates 315 have the same structure, which reduces the procurement of parts while achieving the same functions and purposes.

[0029] Similarly, the cross-section of the lower guide plate 335 is also L-shaped. The two L-shaped lower guide plates 335 form a cigarette clip channel, which can limit the conveying position and angle of the clip.

[0030] In another preferred embodiment, the clamping assembly 50 further includes a pressure plate driver 57 connected to the pressure plate 55 for driving the pressure plate 55 to move up and down, and a push plate driver 53 connected to the lower push plate 51 for driving the lower push plate 51 to move up and down. The lower push plate is located below the clip bin 337. After the clip is conveyed to the clip bin 337, the clip lands on the lower push plate. Specifically, both the pressure plate driver 57 and the push plate driver 53 are cylinders. After the tobacco leaf conveying mechanism conveys the tobacco leaves to the clip-closing station, the lower push plate pushes the clip on the clip bin 337 upward, and the pressure plate driver 57 drives the pressure plate 55 to press down and displace to the clip-closing station to clamp the tobacco fork and the clip. After the tobacco fork and the clip are clamped, they are clamped by a manipulator and sent to the tobacco clip sending mechanism to send out the tobacco clip, realizing automatic clip-closing and improving production efficiency.

[0031] The tobacco clip automatic clip-closing mechanism provided by the embodiment of the present invention automatically conveys the tobacco fork and the clip to the clip-closing station through the provided tobacco fork conveying assembly 31 and the clip conveying assembly 33. After a plurality of tobacco forks and clips are placed on the tobacco fork conveyor belt 313 and the clip conveyor belt 333, they are automatically conveyed to the clip-closing station one by one in an orderly manner. Then, the lower push plate 51 and the pressure plate 55 of the clamping assembly 50 generate relative movement to clamp the tobacco fork and the clip at the clip-closing station. During the conveying process of the tobacco fork and the clip, there is no need to change their movement states through additional structures. They can be directly conveyed to the clip-closing station to realize the clamping of the tobacco fork and the clip. The processing actions are simplified, realizing automatic clip-closing and greatly improving work efficiency.

[0032] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
