Description

Technical Field

[0001] The utility model belongs to the technical field of internal mixer manufacturing, in particular to an environmentally friendly internal mixer for processing polyvinyl chloride film. Background Art

[0002] Internal mixer is a kind of mechanical equipment used in rubber industry. It is widely used in rubber industry. It can effectively mix and process rubber materials and improve the quality and performance of rubber, such as strength, wear resistance, cold resistance, etc. At the same time, internal mixer can also control the molding and vulcanization process of rubber to meet specific product requirements. By controlling the processing conditions and the speed of the roller, the internal mixer can adjust and change the physical and chemical properties of rubber. It is often used in the production of rubber products such as tires, rubber tubes, rubber seals and other processing and manufacturing fields.

[0003] Common internal mixers usually rely on gravity and the push of subsequent materials to make the materials sent out of the internal mixer flow into the receiving hopper. After the internal mixer has been running for a long time, the rubber will stick to the discharge structure, resulting in increased resistance to the advancement of subsequent materials during the discharge process. In addition, without the application of external force, the flow rate of rubber in the discharge pipe of the internal mixer is also slow, which can easily cause the rubber to be blocked in the discharge pipe and affect the smooth flow of the rubber.
