DETAILED DESCRIPTION

[0023] As Figures 1-4 shown, the utility model provides a technical scheme: a paper product cutting device, including cutting table 1, the top fixed mounting of cutting table 1 has support 2, the outer wall fixed mounting of support 2 has No. 1 air cylinder 3, the piston end fixed mounting of No. 1 air cylinder 3 has positioning block 4, the bottom detachable mounting of positioning block 4 has cutting knife 5, starting No. 1 air cylinder 3 drives positioning block 4 to move down, and positioning block 4 will drive cutting knife 5 synchronous downward movement when moving down, and the cutting of paper product can be carried out through the cutting knife 5 of moving down, the top fixed mounting of cutting table 1 has No. 2 air cylinder 6, and the piston end fixed mounting of No. 2 air cylinder 6 has clamping plate 7, and the paper product needing cutting is placed on cutting table 1, then No. 2 air cylinder 6 is started again and drives clamping plate 7 to clamp the paper product, and cutting table 1 is provided with protection mechanism 8 for protecting cutting knife 5, and the protection mechanism 8 can be protected when cutting knife 5 is idle, to prevent staff from accidentally touching cutting knife 5, and cutting table 1 is provided with splash-proof mechanism 9 for preventing the splashing of debris, and the splash-proof mechanism 9 can be blocked to the paper cutting process in the splashing of debris, to prevent the splashing of debris to the surrounding staff.

[0024] The above-mentioned protection mechanism 8 includes rotating rod 81, hollow rod 82, cross bar 83, protective cover 84, rotating rod 81 is rotatably connected on the outer wall of support 2, the outer wall fixed mounting of rotating rod 81 has protective cover 84, and the rotating rod 81 can drive protective cover 84 to cover cutting knife 5, and the protective cover 84 can protect cutting knife 5, to avoid staff from accidentally touching cutting knife 5 during feeding, to avoid the occurrence of safety accidents, hollow rod 82 is fixedly installed on the outer wall of rotating rod 81, cross bar 83 is fixedly installed on the outer wall of positioning block 4, the outer wall of cross bar 83 is attached to the inner wall of hollow rod 82, and the positioning block 4 can drive rotating rod 81 to rotate on the outer wall of support 2 while moving up and down in cooperation with cross bar 83 and hollow rod 82.

[0025] The splash-proof mechanism 9 comprises a baffle cover 91, a through slot 92 and an L-shaped rod 93. The baffle cover 91 is slidingly connected to the inner wall of the cutting table 1 and penetrates the cutting table 1. When paper scraps splash during the cutting of the paper product by the cutting knife 5, the baffle cover 91 can block the splashing paper scraps to prevent the paper scraps from splashing outward and hurting the surrounding workers. The through slot 92 is formed in the baffle cover 91, and the L-shaped rod 93 is fixedly installed on the outer wall of the rotating rod 81 and abuts against the inner wall of the through slot 92. The baffle cover 91 can slide on the inner wall of the cutting table 1 by the cooperation of the rotating rod 81 and the through slot 92.

[0026] Working principle: first, place the paper product to be cut on the cutting table 1, then start the second air cylinder 6 to drive the clamping plate 7 to clamp the paper product, and then start the first air cylinder 3 to drive the positioning block 4 to move downward. The positioning block 4 moves downward while driving the cutting knife 5 to move downward synchronously, so that the cutting knife 5 can cut the paper product. At the same time, the positioning block 4 moves downward while driving the cross rod 83 to move synchronously. At this time, the cross rod 83 abuts against the inner wall of the hollow rod 82 and moves downward to push the hollow rod 82, so that the hollow rod 82 drives the rotating rod 81 to rotate on the outer wall of the support 2. At this time, the rotating rod 81 drives the protective cover 84 to gradually move away from the cutting knife 5, so that the cutting knife 5 is exposed to cut the paper product. When the cutting is completed, the first air cylinder 3 is started again to drive the positioning block 4 to move upward, so that the positioning block 4 drives the cutting knife 5 to move upward. At this time, the positioning block 4 drives the cross rod 83 to move upward synchronously.

At this time, the rotating rod 81 drives the protective cover 84 to gradually move close to the cutting knife 5. When the two groups of rotating rods 81 drive the two groups of protective covers 84 to abut against each other during rotation, the protective cover 84 can cover the cutting knife 5 as a whole. At this time, the worker can take the paper product cut on the cutting table 1. At this time, under the protection of the protective cover 84, the worker can avoid accidentally touching the cutting knife 5 during feeding and discharging, so as to avoid safety accidents.

[0027] When the rotating rod 81 drives the protective cover 84 to gradually move away from the cutting knife 5, the rotating rod 81 drives the L-shaped rod 93 to rotate synchronously, at this time, the L-shaped rod 93 moves in close contact with the inner wall of the through groove 92, and the L-shaped rod 93 pushes the blocking cover 91 upwards, so that the blocking cover 91 slides upwards on the inner wall of the cutting table 1, and the upward sliding of the blocking cover 91 covers the paper product to be cut on the cutting table 1, when the cutting knife 5 cuts the paper product and paper scraps fly, the blocking cover 91 can block the flying paper scraps, so as to prevent the flying paper scraps from hurting the surrounding workers, when the rotating rod 81 drives the protective cover 84 to gradually move close to the cutting knife 5, the rotating rod 81 drives the L-shaped rod 93 to rotate synchronously, at this time, the L-shaped rod 93 moves in close contact with the inner wall of the through groove 92, and the L-shaped rod 93 pushes the blocking cover 91 downwards, so that the blocking cover 91 slides downwards on the inner wall of the cutting table 1, and the downward sliding of the blocking cover 91 exposes the cut paper product on the cutting table 1, so as to facilitate the workers to carry out feeding and discharging.

[0028] The above is a detailed description of the utility model, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the utility model are within the protection scope of the utility model.
