An insulation pipe 20 is fixedly connected to the end of the connecting pipe 19 away from the preheating cylinder 1. The insulation pipe 20 is spirally arranged, and its outer surface is fixedly connected to the transfer tank 9.

[0028] Working principle: The cable material is conveyed from the feed pipe 26 into the preheating cylinder 1 and heated by the electric heating plate 25.

The rotation of the first screw rod 3 drives the baffle 4 to rotate, thereby driving the stirring rod 5 to revolve around the first screw rod 3 as the axis. While revolving, the stirring rod 5 also rotates on its own axis due to the interaction between the connecting gear 6 and the fixed gear 7.

The stirred cable material enters the transfer tank 9 through the first connecting pipe 8. At this time, the preheating cylinder 1 will preheat the next batch of cable material again.

The heat generated inside the preheating cylinder 1 enters the heat preservation pipe 20 through the connecting pipe 19 to keep the inside of the transfer barrel 9 warm and reduce the heat loss inside the transfer barrel 9. The cable material inside the transfer barrel 9 enters the extrusion cylinder 15 through the second connecting pipe 14. The third motor 17 drives the second screw 18 to rotate and transport the cable material. The material is heated, melted and extruded by the multiple heaters 16 set on the extrusion cylinder 15.
