technical field

The invention relates to the technical field of rubber slicing, in particular to a high-efficiency rubber slicing device.

Background technique

At present, rubber slicing is mostly realized by the combination of a cutter and a chopping board. When a traditional slicer cuts a rubber block, when the cutter is close to the chopping board, the rubber needs to be tightly fitted by the cutter and the chopping board to cut off the rubber due to the elasticity of the rubber. In this way, the cutter collides with the cutting board many times for a long time, causing the edge of the cutter to break and damage the cutting board. Even if the cutter is made of high-quality materials, the cutting edge of the cutter will be in frequent contact with the cutting board, which will easily lead to passivation of the knife edge.
