By placing the carton to be cut on the workbench 1, the pressing assembly 3 can limit the top corners of the carton, so that the carton will not move arbitrarily on the workbench 1, so that the cutting assembly 2 can smoothly cut the carton. The pressing assembly 3 includes a front pressing module 31, a rear pressing module 32, a left screw rod 33 and a right screw rod 34. The left screw rod 33 and the right screw rod 34 are both rotatably installed on the workbench 1 and the front pressing module 31 and the rear pressing module 32 are inserted. The left screw rod 33 includes a front thread segment 331 and a rear thread segment 332 with opposite thread directions. The block 31 is threadedly matched with the front threaded section 331, and the rear pressing module 32 is threadedly matched with the rear threaded section 332. Since the left screw rod 33 and the right screw rod 34 are both inserted with the front pressing module 31 and the rear pressing module 32, the left screw rod 33 and the right screw rod 34 can be rotated to make the front pressing module 31 and the rear pressing module 32 move along the length direction of the left screw rod 33 and the right screw rod 34, thereby changing the distance between the front pressing module 31 and the rear pressing module 32, even if the front pressing module 31 and the rear pressing module 32 are close to or away from each other, so that the front pressing module 31 can contact the two top corners on the front side of the carton, and the rear pressing module 32 can contact the two top corners on the rear side of the carton to achieve the limitation of the carton located on the workbench 1. Since the distance between the front pressing module and the rear pressing module is adjustable, it can adapt to cartons of more sizes to achieve the limitation of their top corners, so that the carton can be cut by the judges.

[0029] Among them, the pressing and holding assembly 3 also includes a left contact plate 35 and a right contact plate 36 fixedly installed on the left screw rod 33 and the right screw rod 34, and the left contact plate 35 and the right contact plate 36 are both against the workbench 1. Since the left contact plate 35 and the right contact plate 36 are respectively fixedly connected to the left screw rod 33 and the right screw rod 34, and the left contact plate 35 and the right contact plate 36 are both against the workbench 1, the left screw rod 33 and the right screw rod 34 can be rotated by rotating the left contact plate 35 and the right contact plate 36 without directly contacting the left screw rod 33 and the right screw rod 34, so that the distance between the front pressing and holding module 31 and the rear pressing and holding module 32 can be adjusted.

The left side of the mounting seat 22 is fixedly installed on the matching panel 11. After the front pressing assembly 3 is located at the front side of the carton and the rear pressing assembly 3 is located at the rear side of the carton to complete the limiting of the carton, the matching cylinder 21 can be started to drive the cutting knife 23 to move to achieve cutting of the carton.

[0033] In addition, it also includes a chip removal component 4 slidably installed on the workbench 1 along the front-back direction, and the chip removal component 4 includes a storage bin 41, a chip suction pipe 42 and a chip remover 43 (similar to the structure of a vacuum cleaner, that is, the fan blades or turbines are driven to rotate at high speed by the internal motor to generate high-speed airflow. At this time, the rapid rotation of the fan blades will form a low-pressure area inside the vacuum cleaner. According to the Bernoulli principle, the pressure will decrease where the flow rate is accelerated. This low-pressure area forms a pressure difference with the atmospheric pressure outside the vacuum cleaner, thereby generating suction. This is a prior art and will not be described in detail here. Please refer to Chinese Patent No. CN202223087470.5 A shearing device for carton production (paragraph 0013), the chip remover 43 is located above the workbench 1, one end of the chip suction pipe 42 is connected to the chip remover 43 and the other end is connected to the storage bin 41, 1. Therefore, after the cutting of the carton is completed, the chip remover 43 can be started to generate suction and then absorb the paper scraps scattered on the workbench 1, the paper scraps can enter the chip suction pipe 42 and then be collected in the storage bin 41 to achieve the collection and cleaning of the paper scraps after the carton cutting is completed; 2. Since the chip remover component 4 is slidably installed on the workbench 1 along the front and rear directions, the chip remover 43 can absorb and collect the paper scraps scattered at different positions on the workbench 1 by adjusting the position of the chip remover component 4.
