Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a tire rubber composition mixer. Background Art

[0002] The utility model patent with the announcement number CN218700314U discloses a rubber mixing device for tires, including a mixing box, two feed pipes are opened on the top of the mixing box, a discharge pipe is installed on the outer wall of the mixing box, a protective shell is installed on the top of the mixing box, and a motor is installed inside the protective shell. In the utility model, raw rubber or plastic glue and compounding agents enter the mixing box through the two feed pipes, and the operator starts the motor through the control panel, and the spiral feeding rod rotates with the driving end of the motor to mix the raw rubber or plastic glue with the compounding agent. By setting a stirring rod, the stirring and mixing effect is improved. By setting a scraper rod and a scraper bar, it is avoided that the inner wall of the mixing box is left with raw rubber or plastic glue and compounding agents, which wastes raw materials and cleans the inner wall of the mixing box to facilitate subsequent mixing, which solves the problem that the existing rubber mixing device for tire processing needs to spend a lot of time to clean the inner wall of the mixing drum after use, which delays the subsequent mixing work. However, when the device is in use, the local heating temperature of the device is too high, which will cause the rubber to sinter. At the same time, the mixing efficiency is low because the rubber is stirred only by rotation. Therefore, improvements are needed. Utility Model Content
