[0033] Working principle

[0034] The rubber mixing machine has a rubber discharging device. When the equipment is started, the servo motor 5 starts to operate. The servo motor 5 is connected with one of the rubber mixing rollers 6 through the gear set 2, drives the rubber mixing roller 6 to rotate, at least two rubber mixing rollers 6 are installed between the two concave side frames 24, and the distance between the two rubber mixing rollers 6 can be adjusted by the lifting hydraulic lifting column 23 to adapt to the processing requirements of materials with different thicknesses. In the rubber mixing process, the material is sent into the rubber mixing gap 9 between the two rubber mixing rollers 6 and is extruded and mixed by the rotation of the rubber mixing rollers 6.

[0035] In order to keep the rubber mixing quality, a cleaning assembly 3 is arranged. The assembly comprises a lifting vertical plate 13, an electric push-pull rod 14, a moving bottom plate 15 and a cleaning brush 16. The electric push-pull rod 14 drives the cleaning brush 16 to move back and forth in the rubber mixing gap 9, thereby cleaning the debris and dust attached to the rubber mixing roller 6. One end of the cleaning brush 16 is provided with an arc-shaped end 17, which can be elastically extended along an arc-shaped track in the rubber mixing gap 9, ensuring thorough cleaning.

[0036] The cleaned debris and dust will fall into the debris groove 7.
