[0002] The layered cutting of rubber is an indispensable link in the application of many rubber products, such as the acoustic covering layer laid on ships, damping materials for cutting in the industrial field, etc. However, due to the high friction coefficient of rubber, and the large friction interface between the cutter and the rubber during layered cutting, a very high heat is generated during cutting, which on the one hand makes the rubber sticky and smokes, reducing the performance; on the other hand, it shortens the service life of the cutter due to high temperature, and cannot be operated continuously, affecting the operation efficiency; at the same time, a large amount of additional power is consumed to balance the friction, which greatly increases the energy consumption. Based on the above problems, there is currently no rubber layered cutting equipment on the market, but the specifications of rubber vulcanization mold are increased, that is, different thickness of mold is used for vulcanization of products with different thickness, which greatly increases the cost if the specifications are various.
