Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a four-sided precision cutting machine for square paper tubes. Background Art

[0002] During the production process of square paper tubes, they need to be cut into paper tubes of different sizes by cutting equipment.

[0003] In the prior art, a Chinese patent with the publication number of CN 206445849 U discloses a paper tube cutting machine, aiming to provide a paper tube cutting machine that can ensure the firm connection of the paper tube to the rotating rod while also making it easy to remove the paper tube from the paper tube. The key points of its technical solution are as follows: it includes a fixed ring, a clamping plate, and convex teeth, etc. When cutting the paper tube, first, the paper tube is sleeved on the rotating rod and simultaneously on the fixed ring. At this time, the motor is started, and the motor drives the rotating rod to rotate at a high speed. At the same time, the fixed ring also rotates at a high speed. While the fixed ring rotates at a high speed, the clamping plate on the fixed ring slides outwards towards the movable groove due to the centrifugal force, so that the convex teeth on the clamping plate slide out of the movable groove and abut against the inner wall of the paper tube, thereby fixing the paper tube through the convex teeth.

[0004] In this patent, through the high-speed rotation of the motor, relative rotation exists between the paper tube and the cutting tool, thereby realizing the cutting of the paper tube. However, there are the following disadvantages: when cutting in this way, during the cutting process, paper scraps will fly, which not only affects the production environment but also is not convenient to clean up.
