Description

Technical Field

[0001] The utility model relates to the technical field of waste rubber processing, in particular to a fully automatic device for cutting and crushing waste rubber. Background Art

[0002] There are two main methods for recycling waste rubber. The first is to crush the waste rubber into particles by mechanical methods. The second is to destroy the chemical network structure of vulcanized rubber through desulfurization technology to make so-called recycled rubber. As for the mechanical method, a crushing device is generally used for crushing.

[0003] The existing rubber crushing device has some shortcomings during use. For example, a large amount of dust will be generated during the crushing process, which will cause great harm to workers. At the same time, during the crushing process, the rubber will be hit towards the inner wall of the machine body by the rotation of the crushing knife, which will easily cause the heated rubber to adhere to the inner wall of the machine body.

[0004] Based on the above problems, we propose a new type of fully automatic device for crushing and pulverizing waste rubber. Utility Model Content
