[0002] Fluid turbine coupling is a coupling that uses fluid power to transmit torque and motion. Its finished products need to be packaged in packaging boxes. During the production process of packaging boxes, the surface of the packaging boxes needs to be printed. In the process of feeding paper to the printing machine, some cardboards whose sizes do not match the paper feeding mechanism of the printing machine will bend downward at the tail, especially without adsorption and bottom support, which will cause creases on the surface and cause defective products. At present, in order to prevent creases on the surface of cardboard during the production of packaging boxes, it is usually necessary to use a cardboard anti-crease device to assist the printing machine in feeding paper.

[0003] The cardboard anti-crease devices on the market usually do not have flexible height and angle adjustment structures and cannot be applied to different printing equipment. Therefore, we propose a cardboard anti-crease device. Utility Model Content
