Through the mutual cooperation between the automatic mixing mill and the conveyor belt rubber turning and pouring device, the rubber material can be in the state of thin pass and accumulation on the mixing mill, so as to meet the requirements of automatic sulfur addition, acceleration and supplementary mixing. The manual operation of the mill is realized, and the hidden safety hazard of manual work in the mill is eliminated. At the same time, the automatic and stable production of rubber materials is realized through the fully automatic control of glue turning and glue pouring devices.
