Description

Technical Field

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

[0002] The open mill is a mixing equipment used in the plastic and rubber industry, mainly used for plasticizing, mixing, sheeting and hot mixing. The open mill is the abbreviation of an open rubber mixing mill, which is a rubber mixing machine with exposed rollers used by rubber factories to prepare plasticized rubber, mixed rubber or perform hot mixing and molding. The automatic rubber turning device of the open mill is a device to assist in feeding the open mill. In the process of feeding and mixing long rubber belts, it can reduce the labor intensity of operators and improve the safety of operation.

[0003] Since the mixing mill needs to turn the materials regularly when mixing them so that the mixing effect between the materials can be better, workers are required to turn the materials aside when mixing the materials. However, the turning mechanisms currently installed on the mixing mills are mostly fixed. If the pressure is too high when turning the materials, the mixed materials may be broken up, which will cause the mixing mill to process the materials multiple times, which is not convenient for improving the mixing efficiency.
