[0002] Mixing machine is a rubber mixing equipment used to mix raw rubber and compounding agents. It can also plasticize natural rubber. Mixing machine is divided into two types: open type rubber mixing machine (referred to as open mixing machine) and closed type rubber mixing machine (referred to as internal mixing machine). When the rubber material is thinly passed on the open mixing machine, the compounding agent is added in the gap between the mixing rollers.

[0003] The existing patent (publication number: CN220548514U) discloses an automatic feeding device for a continuous mixer, including a mixing box and a second motor, a first gear is fixedly installed at the output end of the second motor, a first motor is fixedly installed at the lower end of the right side of the outer surface of the mixing box, a first stirring rod is fixedly installed at the output end of the first motor, the left side of the first stirring rod is movably connected to the lower end of the left side of the inner cavity of the mixing box through a bearing, and a rotating tube is movably connected to the middle end of the top of the mixing box through a bearing. The utility model realizes that the automatic feeding device for a continuous mixer can achieve uniform mixing of raw rubber and compounding agent during the feeding process through the coordination of the mixing box, the first motor, the second stirring rod, the feed hopper, the partition, the second gear, the rotating tube, the first gear, the second motor, the first stirring rod and the feeding valve, effectively ensuring the efficiency and quality of the overall processing operation, and facilitating the use of personnel.
