Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable production, and specifically relates to an extruder for processing and producing heat-resistant wires and cables. Background Art

[0002] At present, the extruder used for processing and producing heat-resistant wires and cables is a kind of equipment specially used for processing and producing heat-resistant wires and cables. The extruder is mainly used to evenly extrude insulating materials, sheathing materials, etc. onto the conductors or cores of wires and cables, thereby forming an insulating layer or sheathing layer with the required thickness and uniformity.

[0003] The prior art authorization announcement number is: CN218660365U, and the name is an extruder for wire and cable production, including a support mechanism, an extrusion mechanism and a preheating mechanism. The extrusion mechanism is located above the support mechanism and is used to extrude the material from the extrusion barrel. The preheating mechanism is located above the extrusion mechanism and is used to preheat the material. When in use, the material enters the inner shell through the feed hopper, and the heating coil is energized to preheat the material. After preheating, the servo cylinder drives the baffle to descend, so that the material enters the fixed shell, and then enters the extrusion barrel through the feed pipe. This method allows the material to quickly reach the required temperature in the extrusion barrel, thereby improving production efficiency;

[0004] However, when this patent is in use, the material becomes sticky after being melted at high temperature, which causes uneven discharge of the material when the equipment is feeding the material into the extrusion barrel. When this patent is in use, when the equipment is placed on an uneven ground, it will cause uneven wear of machine parts, thereby shortening the service life of the machine.

[0005] The authorization announcement number in the prior art is: CN213339864U, and the name is an extruder for cable production, including an extrusion tube, a feed box and a barrel, the feed box is provided with a feed inlet and a discharge port, the barrel is located in the feed box, and the bottom thereof is provided with a feed inlet, which is connected to the feed inlet through a material guide pipe, the outside of the barrel is provided with a discharge port, and the inside of the barrel is provided with a discharge device to drive the plastic particles to move toward the discharge port, and the outside of the feed box is provided with a fan and a heating device to generate hot air to heat the plastic particles, remove moisture, shorten the melting time, avoid the generation of bubbles, and improve the coating quality, and the plastic particles enter the extrusion tube through the material guide pipe, the barrel and the discharge port to complete the extrusion process;

[0006] However, when the patent is used, the material tends to become sticky after being melted at high temperature, which causes uneven material discharge when the equipment feeds the material to the extrusion pipe. Utility Model Content
