[0002] In the existing folder gluer, the transmission shaft is usually directly exposed outside the equipment, which is prone to corrosion, aging, and damage after long-term use. When the shaft rotates, it will bring safety risks to the operator. There is a cylindrical protective cover on the transmission shaft, but even in the same folder gluer, the length, shaft diameter and other parameters of each transmission shaft are different. If different sizes of cylindrical protective covers are set for the transmission shaft specifications, it will inevitably lead to an increase in equipment costs and it is difficult to promote in the industry.

[0003] A patent with publication number CN204674093U proposes a protective device for the transmission shaft of a folder-gluing machine, which includes a connection assembly, a spiral monomer, a locking ring, and a reinforcement chamber.

The locking ring can hoop the spiral monomer to maintain the stability of its shape. It is formed by a metal strip being wound around the same axis multiple times to form multiple connected spiral monomers. Of course, alternatively, the spiral monomers can also be connected by adhesives, welding, etc., but the following problems still exist in this patent:

[0004] The existing transmission shaft protection assembly only uses a spiral monomer for protection, which does not have a good protection effect, is inconvenient to adjust and use the protection assembly, and is not easy to install and use.

[0005] In view of the above problems, it is necessary to design a folder-gluing machine transmission shaft protection device to overcome the above problems. Utility Model Content
