In the technical field of rubber and plastic processing, a plurality of products need to be smelted and blended by an internal mixer and an open mill, products such as natural rubber, synthetic rubber, ethylene-vinyl acetate copolymer and the like are generally subjected to vulcanization molding by a vulcanizer and injection molding by a novel process, the raw materials are dispersed and mixed and melted by the internal mixer and the open mill, and then the products can enter an injection or flat vulcanizing machine for vulcanization molding after granulation or sheet discharge. After the raw material formula according to the specific technical requirements is mixed by an internal mixer, the raw materials which are originally colloid, particles and powder and the batch materials are fused and melted into a micelle. But the dispersion degree between various batch materials and rubber (plastic) in the raw materials is low, and only the common dispersion degree is achieved. In order to fully disperse various components in the micelle into sheet materials or granular materials which can enter a forming process, the sheet materials or the granular materials are subjected to thick-passing, thin-passing, triangular bag making, thick-thin kneading and refining by an open mill according to the industrial terminology, and then the sheet materials or the granular materials are prepared into rubber particles by a sheet discharging machine or a granulating machine. These procedures have traditionally been manually operated both on stand-alone machines and from machine to machine.

The rubber mixing process has the disadvantages that the work efficiency is low, the labor intensity is high, the rubber material is conveyed among independent machines manually, the machines are in idle running due to the fact that the rubber material is influenced by personal factors and cannot meet the rhythm of flow operation, one traditional habit is that the labor intensity is conceivably large because the rubber material is conveyed between the independent machines and one traditional habit is that the weight of one traditional rubber material is 70-80 kg; secondly, the technical standard is difficult to control, the operation is completely operated by hands no matter the glue is fed, the glue is fed or the triangle package is formed, the execution degree of the technical standard in the operation process completely depends on the field control of an operator, the operation cannot be completely and strictly executed according to the standard, and the quality of the product cannot be unified and stable; finally, the labor cost is high, and according to the operation of the traditional standard, each machine is operated by at least one operator, so the labor cost is extremely high. The company has already solved the problems, for example, the automatic rotary feeding device has a major breakthrough in solving the automatic operation scheme between the open mills, but has some disadvantages in the aspects of equipment cost, operation cost and maintenance cost, raw material temperature maintenance and the like.
