[0002] In the production and manufacturing process of rubber products such as rubber plates and rubber blocks, the formed rubber products need to go through the key step of cutting. The traditional cutting process generally relies on mechanical cutters, however, this method not only produces a large amount of dust, seriously pollutes the working environment and harms the health of workers, but also is accompanied by a series of problems such as low cutting efficiency, high energy consumption, rough and uneven cutting surface and rapid tool wear. In view of this, in recent years, the rubber product manufacturing industry has begun to explore and adopt hot cutting technology as an alternative solution, such as flame cutting, hot knife cutting and laser cutting.
