Abstract

The invention belongs to the technical field of shafts, in particular to a transmission shaft, which comprises an outer shaft and an inner shaft; the inner part of the outer shaft is a cavity structure, and the inner shaft is inserted into the outer shaft; There is a rotating groove; a rotating plate is evenly arranged on the outer wall of the inner shaft, the rotating plate is rotated and inserted into the rotating groove, one side of the rotating plate is connected to the side wall of the rotating groove through an elastic sealing bag, and the other side of the rotating plate is connected by an air bag On the other side wall of the rotating groove; a group of air blowing ports are evenly arranged on the outer shaft, and the air blowing ports are located above the elastic sealing bag; when the outer shaft continues to rotate due to inertia, the rotating plate will squeeze the elastic sealing bag, and at the same time Control the gas generated by the elastic sealing bag to be blown out from the air blowing port, and clean up the printing materials left on the outer ring of the outer shaft after printing the printed products, so as to avoid using the drive shaft to print the printed products later, which will affect the quality of the printed products. printing quality, thereby improving the practicality of this drive shaft.

Description

technical field

[0001] The invention belongs to the technical field of shafts, in particular to a transmission shaft. Background technique

[0002] The shaft (shaft) is a cylindrical object that goes through the middle of the bearing or the middle of the wheel or the middle of the gear, but there are also a few of them that are square. A shaft is a mechanical part that supports and revolves with a rotating part to transmit motion, torque or bending moment.

[0003] In the prior art, there is a shaft for printing printed products. In printing, one side of the shaft is first immersed in ink, and the ink will adhere to the outer peripheral surface of the shaft. Printing on printed products; however, after the printing of printed products is completed, there are still residues on the outer ring of the shaft. If the residues are not cleaned up, the surface of the shaft will be damaged under the action of post-printing pressure and heat. It becomes rough and affects the printing...
