AI Technical Summary
The existing paper cutting machines are prone to cutting errors due to cardboard sliding during the cutting process, and lack a synchronous auxiliary clamping mechanism, which affects the efficiency of the cutting work.
A paper cutting machine for carton production is designed. When the lifting mechanism drives the cutting parts into the cardboard, the ball at the bottom of the corner block conflicts with the edge surface of the cutting groove of the cardboard, and dynamically synchronously clamps are used to increase the cutting depth. As the cutting depth increases, the ball shrinks into the corner block, and the clamping force increases, improving cutting stability.
It effectively improves the stability of cardboard cutting work, reduces cutting errors, and increases the clamping force synchronized with the cutting depth through dynamic clamping, improving cutting efficiency.

Technical Field
[0001] The utility model relates to the technical field of paper cutting, in particular to a paper cutter for carton production. Background Art
[0002] As an indispensable part of modern logistics, packaging cartons bear the important responsibilities of containing, protecting products and making them beautiful. During the production process of cartons, the cardboard needs to be pre-cut, so that the cut cardboard can be folded and glued to form the initial carton shape.
[0003] In the existing cutting process, the cardboard is first placed on the cutting table, and then the cutting component is driven by the displacement component to cut the cardboard. When some blades quickly perform cutting depth and steering control, the cardboard is easy to slide on the cutting table, resulting in cutting errors. If a positioning clamping mechanism is used to clamp the cardboard, it is necessary to perform several reset operations after the cardboard is cut, which is inconvenient for unloading the cardboard. There is a lack of a synchronous auxiliary clamping cardboard mechanism to solve this problem. Utility Model Content
