For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The working principle of the above embodiment is:

[0035] (1) When the extrusion device is needed, the raw materials of the cable are put into the feed bin 7, and then the motor 202 is started, so that the output shaft of the motor 202 starts to drive the screw rod 3 to rotate, and the output shaft of the motor 202 starts to drive the first gear 203 to rotate. At this time, the first gear 203 starts to drive the second gear 204 to rotate, so that the connecting rod 205 starts to drive the belt 206 to transmit, and then the movable rod 207 starts to rotate and drives multiple stirring rods to mix and stir the raw materials of the cable to avoid problems such as blockage of the raw materials of the cable.

[0036] (2) When the raw material of the cable is driven to the right by the screw rod 3 inside the box body 1, the raw material moves to the inside of the extrusion barrel 5 through the extrusion port, and the aqueous solution in the water tank 402 can be pumped out by the water pump 401 and transmitted to the inside of the cavity through the liquid outlet pipe 404. At this time, the raw material and the aqueous solution exchange heat, so that the raw material is quickly cooled down. The heated aqueous solution flows back to the inside of the water tank 402 through the reflux pipe 405, and the temperature of the aqueous solution in the water tank 402 can be reduced by the refrigeration plate, so that the cooling effect is better.
