[0002] The sealing ring is a ring-shaped object made of rubber as raw material, generally used for sealing and fixing. The sealing ring needs to be pressed in the mold first during production. When the molded product is vulcanized, the rubber quickly fills the mold cavity, and the excess part overflows to form overflowing glue, that is, flash. In order to make the product meet the specified size and ensure the appearance quality.

[0003] After searching, the application document of Chinese patent authorization announcement number CN213860287U discloses a rubber ring trimming device, including a work surface, a driving motor, a linkage mechanism, a sleeve and a nozzle. The driving motor drives the turntable to rotate, the sleeve drives the rubber ring body to rotate, and the trimming device body trims the rubber ring body. The debris generated during trimming is blocked by a transparent cover to prevent the debris from splashing outside the work surface. The linkage mechanism arranged on the right side of the driving motor drives the connecting rod to rotate, and the connecting block threadedly connected to the outer side of the connecting rod slides, the connecting block drives the nozzle to slide, and the nozzle sprays gas.

[0004] With respect to the above-mentioned related technologies, the device, by setting a spring and a limit block, cannot effectively adjust the size of the sleeve according to the size of the sealing ring, so it is urgent to design a trimming device for the sealing ring to deal with these problems.
