[0002] To enhance the aesthetics of chopsticks or add branding, various patterns need to be printed on them using pad printing equipment. During operation, the chopsticks are placed with the printing end facing the pad printing end, which then moves towards the chopsticks to complete the printing process. To improve the stability of the printing process, a positioning mechanism needs to be added to the equipment to ensure stability during printing. This positioning mechanism is located directly below the pad printing mechanism. Since different parts of the chopsticks have different dimensions, the positioning mechanism needs to be changed promptly according to the size requirements of the chopsticks, reducing the likelihood of reuse and increasing production costs. To address this issue, this application proposes a positioning mechanism that can be adjusted promptly according to usage needs, adapting to chopsticks of different sizes and optimizing the positioning and clamping of different parts of the chopsticks, thus improving production equipment.

[0018] Reference Figures 1 to 7 The embodiments of this utility model will be further described below.

[0019] A positioning mechanism for a chopsticks pad printing device includes a worktable 1 located below the pad printing mechanism. A positioning clamping assembly is provided on the worktable 1. The positioning clamping assembly includes a positioning plate 2 fixed to the worktable 1 and a clamping device 3 slidably engaged on the positioning plate 2. The positioning plate 2 has multiple sets of adjustment grooves 20. The clamping device 3 includes a clamping plate 30 and at least two clamping seats 31, forming a positioning area 32 between the two clamping seats 31. One end of the clamping plate 30 has a slide rail 300, and the other end is connected to a drive assembly 34. The bottom of the clamping seat 31 has a slider adapted to the adjustment groove 20. 310, with a second slider 311 at its end, the second slider 311 extending into the slide rail 300 of the clamping plate 30 for sliding engagement. When the driving assembly 34 drives the clamping plate 30 to move forward toward the worktable 1, the first slider 310 on the clamping seat 31 moves toward the tail end of the adjustment groove 20, the two clamping seats 31 separate from each other, and the positioning area 32 expands. When the driving assembly 34 drives the clamping plate 30 to move backward away from the worktable 1, the first slider 310 on the clamping seat 31 moves toward the head end of the adjustment groove 20, the two clamping seats 31 move closer to each other, and the positioning area 32 shrinks.

[0020] The drive assembly 34 includes a base 340 and a movable shaft 341 that slides through the base 340. Both ends of the movable shaft 341 extend outside the base 340, one end is fixedly connected to the clamping plate 30, and the other end is provided with a nut 342 that is threaded into it.

[0021] The clamp 31 has a retractable abutment 35 on one side corresponding to the positioning area 32. The clamp 31 has a telescopic groove 312 for sliding engagement of the abutment 35. One end of the abutment 35 has a spring 350, and the other end has two arc-shaped abutments 351. The arc-shaped abutments 351 have guide slopes 352, which are inclined downwards from the upper opening of the positioning area 32 toward the bottom of the positioning area 32.

[0022] Working principle of Example 1: When it is necessary to adjust the size of the positioning area 32, first loosen the nut 342 on the movable shaft 341, and then push the movable shaft 341. When the driving clamp 30 moves towards the worktable 1, the clamp 31 is simultaneously driven to slide along the positioning plate 2. The slider 310 on the clamp 31 slides in the adjustment groove 20. When the adjustment groove 20 is curved, the slider 311 on the clamp 31 will slide along the slide 300 of the clamp 30. When the clamp 31 slides along the clamp 30, the positioning area 32 between the two clamps 31 is expanded, which is suitable for positioning and clamping chopsticks of larger size. When the movable shaft 341 drives the clamping plate 30 to move in the opposite direction to the worktable 1, the slider 310 on the clamping seat 31 moves along the adjusting groove 20 to its head. Due to the bending of the adjusting groove 20, the slider 311 on the clamping seat 31 slides along the slide rail 300 of the clamping plate 30. The positioning area 32 formed between the two clamping seats 31 shrinks, suitable for positioning smaller chopsticks. After adjusting the size of the positioning area 32, it is fixed to the movable shaft 341 with bolts to fix the position of the clamping seat 31. Then, the part of the chopstick to be printed is clamped in the positioning area 32. Because retractable abutments 35 are provided on both sides of the positioning area 32, the extension and retraction of the abutments 35 further clamps and positions the chopsticks. At the same time, a guide slope 352 is provided on the arc-shaped abutment 351 to facilitate the insertion of the chopsticks into the positioning area 32. The number of clamping seats 31 can be increased to allow for simultaneous adjustment of multiple positioning areas 32.

[0023] Working principle of embodiment 2: The drive assembly 34 includes a base 340 and a movable rod 343 that is movably engaged within the base 340. The movable rod 343 is provided with a toothed belt 344, a gear 345 meshes with the toothed belt 344, a screw 346 is connected to the gear 345, and the screw 346 extends to the outside of the base 340 and is provided with a handwheel 347.

[0024] By rotating the handwheel 347, the screw 346 is driven to rotate, and the screw 346 drives the gear 345 to rotate. When the gear 345 is running, it drives the movable rod 343 to move back and forth through the toothed belt 344. The back and forth movement of the movable rod 343 drives the clamp 31 to move back and forth, thereby realizing the adjustment of the size of the positioning area 32.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
