Its main function is to prevent the foam rubber from leaking at the pipe mouth. The foam rubber end cap sealing ring is a simple, easy-to-use and economical foam rubber accessory that can effectively protect the foam rubber pipe mouth from damage and improve the service life and safety of the foam rubber.

[0003] In the recycling production process of the foam end cap sealing ring, a sealing ring cutting machine is usually required to cut the sealing ring. For example, a sealing ring cutting machine disclosed in the Chinese patent with the authorization announcement number CN207105042U has a simple structure and can quickly realize high-precision cutting of rubber sealing rings. During the working process, the sealing ring raw material is fixed by the positioning knife through the lifting device.
