Description

Technical Field

[0001] This utility model relates to the field of rubber seal processing technology, specifically to an automatic rubber seal cutting machine. Background Technology

[0002] Rubber seals are a common type of seal in the mechanical field. Their raw material is a rectangular sheet of rubber. During the production and processing, the rubber sheet needs to be cut into strips, and then the ends of the rubber strips are fused together to form a sealing ring. This requires the use of strip cutting equipment for processing rubber seals.

[0003] In the prior art, application number 202320757360.0 discloses a high-efficiency strip cutting device for rubber seals. Cutting steel wires are fixedly installed on the inner sides of the two mounting boxes, and the ends of the two positioning rods are slidably engaged in the interior of the groove. When the above device uses heating wire to cut rubber, if the temperature is too high, it will cause the rubber to scorch and deform. Each cut can only cut a single rubber sheet. The width of the cut rubber strip needs to be manually controlled by the operator. Furthermore, the quality of the cut rubber strip cannot be inspected in time, which can easily affect the effect of subsequent sealing ring processing.
