The cooling and regulating component 5 is started when necessary, and the heating extrusion mechanism 3 is cooled by the blower 26 and the circulating water network 25 to ensure temperature stability.

[0028] Beneficial effects: Integrated design: Each component is linked through the controller 6, which improves the integrity and coordination of the equipment.

[0029] Precise temperature control: The combined use of heating and cooling systems ensures the temperature stability of the rubber during the extrusion process, which is beneficial to improving product quality.

[0030] High degree of automation: reduces manual intervention and improves production efficiency and safety.

[0034] The working principle and beneficial effects of the above technical solution are: Working principle: On the basis of Example 1, the mounting assembly 1 provides a stable support for each component. The power mechanism 2 reduces the speed and increases the torque through the reducer 14 to meet the extrusion requirements of the conveying screw 23 for the rubber. When the power mechanism 2 is working, the drive motor 12 receives the command of the controller 6 to operate, and the drive motor 12 drives the coupling 13 to drive the input shaft end of the reducer 14 to rotate. The reducer 14 amplifies the torque and drives the conveying screw 23 to rotate. When the rubber raw material enters the heating extrusion mechanism 3 from the feeding mixing mechanism 4, the conveying screw 23 pushes the rubber forward during the rotation process, and at the same time, the electric heating layer 19 in the heating sleeve 17 works to uniformly heat the rubber. The porous filter plate 21 is located at the right end inside the conveying pipe 16, which is used to filter out impurities in the rubber and decompose the rotational force to ensure the quality of the extruded product. Finally, the rubber is output from the extruder head 24.

The water supply pump 30 extracts water from the water storage tank 27 and sends it to the circulating water network 25 through the water supply main pipe 31 and the water supply branch pipe 33.
