[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model has a limitation: while conveying cardboard via a conveyor belt, the device uses rubber collars to limit the cardboard and prevent it from shifting. However, the rubber collars are fixed to the outside of the conveyor belt and can only position cardboard of a fixed size. When the cardboard sizes are different, the rubber collars cannot effectively position the cardboard, resulting in a narrow application range. Therefore, it is necessary to improve the anti-shifting paper packaging box processing and cutting device to solve the above problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1-5This utility model provides an embodiment of an anti-deviation paper packaging box processing and cutting device, including a support frame 1 and support legs 4, and further including a first slider 26, rollers 27, positioning frames 28 and a cutting mechanism. The support legs 4 are fixedly connected to the bottom of the support frame 1, and the cutting mechanism is arranged on the right side of the support frame 1. The first slider 26 is slidably connected inside the support frame 1, and the rollers 27 are rotatably connected inside the first slider 26. The positioning frame 28 is fixedly connected to the top of the first slider 26. The positioning frame 28 moves to a suitable position to position the cardboard. The bidirectional screw 24 rotates to drive the two positioning frames 28 to move synchronously, moving away from or towards each other. The distance between the two positioning frames 28 can be adjusted by the rollers 27, which can reduce the distance between the first slider 26 and the positioning frame 28. The friction of 26 makes the movement smoother and more precise. When the conveyor belt 23 conveys the cardboard, the cardboard can be positioned by two positioning frames 28 to keep it in the center and prevent it from shifting. Then, the lateral and height positions of the cutting blade 310 are adjusted by the one-way screw 34 and the electric telescopic rod 36, so as to cut the cardboard in conjunction with the through groove of the lower blade holder 31 to cut the cardboard into the appropriate size. The support frame 1 has a groove at the corresponding position of the first slider 26, and the first slider 26 slides inside the groove. The roller 27 is rolled and connected inside the groove. The groove limits the first slider 26, and the roller 27 reduces the friction between the first slider 26 and the support frame 1, ensuring service life and smoother movement.

[0023] See also Figures 1-4 In this embodiment, a first motor 21 is fixedly connected to the front of the support frame 1. A conveyor roller 22 is fixedly connected to the output end of the first motor 21. The conveyor roller 22 is rotatably connected inside the support frame 1. A conveyor belt 23 is driven to the outside of the conveyor roller 22. A bidirectional screw 24 is rotatably connected inside the support frame 1. A sliding frame 25 is threaded to the outside of the bidirectional screw 24. The sliding frame 25 is slidably connected inside the support frame 1 and fixedly connected to the inner side of the first slider 26. While the cardboard is conveyed by the conveyor belt 23, the cardboard can be positioned by two positioning frames 28. To prevent cardboard misalignment, two sliding frames 25 are provided, and the two sliding frames 25 are symmetrically threaded to the outside of the bidirectional screw 24. Rotating one bidirectional screw 24 can drive both bidirectional screws 24 to move, ensuring that the two positioning frames 28 are always in a symmetrical and centered position. This is convenient to use and saves manufacturing costs. The positioning frames 28 have through slots at corresponding positions on the conveyor belt 23, and the positioning frames 28 are set on the outside of the conveyor belt 23 through the through slots. This allows the position of the positioning frames 28 to be adjusted at any time without affecting the operation of the conveyor belt 23, and they will not interfere with each other.

[0024] See also Figure 1 , Figure 5In this embodiment, the cutting mechanism includes a lower blade holder 31, which is fixedly connected to the right side of the support frame 1. A mounting frame 32 is fixedly connected to the top of the lower blade holder 31. A second motor 33 is fixedly connected to the front of the mounting frame 32. A one-way screw 34 is fixedly connected to the output end of the second motor 33. The one-way screw 34 is rotatably connected inside the mounting frame 32. A second slider 35 is threadedly connected to the outside of the one-way screw 34. The second slider 35 is slidably connected inside the mounting frame 32. An electric telescopic rod 36 is fixedly connected to the bottom of the second slider 35. A mounting block 37 is fixedly connected to the bottom of the electric telescopic rod 36. A third motor 38 is fixedly connected to the right side of the mounting block 37. A rotating shaft 39 is fixedly connected to the output end of the third motor 38. The rotating shaft 39 is rotatably connected inside the mounting block 37. A cutting blade 310 is provided on the outside of the rotating shaft 39. The position of the cutting blade 310 can be adjusted by a one-way screw 34 and an electric telescopic rod 36. It can be applied to the cutting of cardboard of different sizes, and has a wider range of applications. The lower blade holder 31 has a through groove at the corresponding position of the cutting blade 310, and the cutting blade 310 passes through the through groove to facilitate the descent of the cutting blade 310 and prevent the cutting blade 310 from cutting the lower blade holder 31 when it descends and passes through the cardboard.

[0025] During operation, the first motor 21 drives the conveyor roller 22, which in turn drives the conveyor belt 23 to transport the cardboard. The bidirectional screw 24 drives the sliding frame 25, which in turn drives the first slider 26. The first slider 26 moves via the roller 27 and simultaneously drives the positioning frame 28. The two positioning frames 28 move synchronously to adjust to the appropriate position to limit the cardboard. Then, the cardboard reaches the corresponding position of the cutting blade 310. The second motor 33 drives the unidirectional screw 34, which rotates and drives the second slider 35. The second slider 35 drives the mounting block 37 to adjust its lateral position. The electric telescopic rod 36 drives the cutting blade 310 to adjust its vertical position. The third motor 38 drives the rotating shaft 39, which in turn drives the cutting blade 310 to rotate, thereby cutting the cardboard.

[0026] Through the above steps, the spacing between the two positioning frames 28 is adjusted according to the size of the cardboard, thereby limiting the positioning of cardboard of different sizes. This solves the problem that the fixed-position rubber collar can only position cardboard of a fixed size, and when the cardboard sizes are different, it is impossible to effectively position the cardboard through the rubber collar.
