Description

Technical Field

[0001] The utility model relates to the technical field of color-changing extruders, in particular to a cable insulation layer rapid color-changing extruder. Background Art

[0002] The extruder head can be divided into right-angle head and bevel head according to the direction of material flow in the head and the angle between the center line of the screw. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then extrude it through the die.

[0003] For example, in the Chinese patent document with publication number CN218342788U, it includes a main body, the outer wall of the main body is fixedly connected with a handle, the inner wall of the handle is provided with a button, the outer wall of the main body is fixedly connected with a sleeve, the outer wall of the sleeve is fixedly connected with a motor box, the outer wall of the motor box is fixedly connected with a belt shell, the outer wall of the belt shell is fixedly connected with a first wheel frame, and the inner wall of the first wheel frame is rotatably connected with an upper hub. When the outer skin of the cable is damaged, the cable can be received into the first mold core by rotating the upper hub and the lower hub, and the upper hub is linked with the motor in the motor box through the belt in the belt shell, so that the lower hub can rotate, thereby achieving the effect of automatic wire feeding, and then the cable is heated by the electric heating core, and when entering the second mold core, it is wrapped with the first layer of outer skin, and when entering the extrusion mold, it is wrapped with the second layer of outer skin, and finally discharged from the extrusion mold.

[0004] However, in the extrusion insulation operation of the wires of the above technical solution, because the wires need to be distinguished by insulation layers of different colors, when the extruder changes colors, it is necessary to completely empty the remaining rubber in the first barrel and the second barrel, and then add new rubber. Only then can the extrusion production of the next color wire insulation layer be carried out. This method of changing colors causes serious waste of materials. Utility Model Content
