Description

Technical Field

[0001] The utility model relates to the field of open mixing mills, in particular to a rubber turning device for an open mixing mill. Background Art

[0002] The mixing mill is an open type of rubber mixing machine, which is widely used in rubber factories to prepare plasticized rubber, mixed rubber or for hot refining and molding. When the mixing mill is in operation, various raw materials are heated and mixed, and then processed through the mixing rollers to prepare plasticized rubber and mixed rubber.

[0003] During the processing on the mixing mill, in order to ensure uniform mixing of the raw materials, the rubber needs to be turned over several times. Usually, a worker is required to hold a rubber cutter to cut off the rubber tape wrapped around the front refining roller as a whole or in part, and turn the rubber. However, since the worker holds the rubber cutter close to the refining roller, the rubber cutter fits against the outer wall of the refining roller, and moves the rubber cutter horizontally, the worker's hand is close to the hot refining rubber and the refining roller, which can easily cause the hand to come into contact with the rubber and the refining roller, causing personal injury.
