[0025] Working principle:

[0026] Since the rubber extruder pours rubber particles into the box 5 when feeding, the internal heating jacket 9 heats the rubber particles into a molten state when the rubber extruder works, and then the molten rubber is extruded through the discharge pipe 10. Some of the rubber will remain inside the box 5 during extrusion, and the box needs to be cleaned.

[0027] Auxiliary cleaning process for rubber extruder box:

[0029] Auxiliary disassembly process of the rubber extruder discharge pipe:

[0030] Connect the external power supply of the second motor 301, start the output shaft of the second motor 301 to rotate and drive the worm 303 to rotate, the rotation of the worm 303 drives the worm wheel 304 and the rotating rod 305 to rotate, and the rotating rod 305 drives the support plate 306 and the discharge pipe 10 away from the box body 5, so that the operator can disassemble and replace the discharge pipe 10 conveniently. According to the above operation, after the operator installs the new discharge pipe 10 on the surface of the support plate 306, start the output shaft of the second motor 301 again to reverse and drive the discharge pipe 10 to return to its original position, completing the auxiliary disassembly process of the discharge pipe, making it convenient for the operator to disassemble the discharge pipe.
