[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] Glue coating machine is also called coating machine, which is mainly used to apply liquid glue on the surface of board, textile, paper box or leather. Among them, the glue coating shaft is a key component of the glue coating machine, and its function is to evenly apply glue on the board. In order to prevent glue from entering the rotating connection between the glue coating shaft and the bearing seat, a sealing ring is usually installed on the glue coating shaft to achieve a waterproof seal between the glue coating shaft and the bearing seat.

[0004] In order to achieve the compression and fixation of the sealing ring, a pressing ring is usually provided on the bearing seat to compress and fix the sealing ring, such as Figure 1 As shown in the figure, the pressing ring is fastened in the bearing seat by interference fit. After a period of use, the pressing ring is prone to loosening and cannot compress the sealing ring, which causes the sealing ring to wear as the rubber-coated shaft rotates, thereby greatly affecting the sealing performance of the sealing ring. In addition, the use of this clamping method also requires high dimensional accuracy of the pressing ring, resulting in high processing and manufacturing costs. Utility Model Content
