Problems solved by technology

[0004] Extrusion is carried out by using extrusion equipment. Conventional extruders do not have the function of crushing cable materials. During the melting process of large particles of cable materials, there is often the problem of insufficient melting, and it is easy to mix solid particles, which seriously affects the extrusion effect. , Moreover, the lack of necessary preheating function is not conducive to the improvement of extrusion efficiency

Embodiment 1

[0029] An insulation extrusion equipment for cable production, including an extruder head 1 for cable extrusion, characterized in that, one side of the extruder head 1 is provided with an extruding and plasticizing mechanism 2 for supplying molten cable material , the number of the extruding and plasticizing mechanism 2 is multiple, at least 2, and its upper end is provided with a feeding mechanism 3 for supplying cable materials.

[0030] In this embodiment, the cable material is fed by the feeding mechanism, enters the extrusion plasticizing mechanism, plasticizes and melts, and finally enters the extruder head to extrude the cable (inner conductor).

Embodiment 2

[0032] Insulation extrusion equipment for cable production in this embodiment, wherein the unloading mechanism 3 includes a hopper 4, a crushing and crushing assembly 5, a first feeding device 6 and a second feeding device 7, and the crushing and crushing assembly 5 is arranged directly below the hopper 4, its upper end communicates with the hopper 4, and its lower end communicates with the upper end of the first feeding device 6. The crushing and crushing assembly 5 is provided with two crushing rollers 8 that are squeezed against each other. The rolling roller 8 is arranged horizontally and symmetrically, and is controlled by a motor to rotate. The first feeding device 6 is a feeding auger, which is arranged obliquely. The upper end of the first feeding device 6 is the feeding end, and the lower end is the discharging end. Its upper end communicates with the rolling and crushing assembly 5, and its lower end communicates with the second feeding device 7. The second feeding de...

Embodiment 3

[0035] In the insulation extrusion equipment for cable production in this embodiment, the rotation directions of the two rolling rollers 8 are opposite, which is convenient for extrusion rolling.

Abstract

The invention discloses an insulating extruding equipment for cable production, which includes an extruding head, and is characterized in that an extruding and plasticizing mechanism is arranged on one side of the extruding head, and a feeding mechanism is arranged on the upper end of the extrusion and plasticizing mechanism, and The material mechanism includes a hopper, a rolling and crushing assembly, a first feeding device, and a second feeding device. The extrusion plasticizing mechanism includes an extrusion cylinder and an extrusion screw. The invention has a simple structure and a reasonable design. It can preheat the cable material and reduce the difficulty of melting. The segmented design of the extrusion screw has the effects of kneading, increasing shear stress, accelerating exhaust and reducing extrusion backflow, which can effectively improve the mixing effect and discharge. Gas efficiency, melting efficiency, to ensure the cable extrusion effect, improve the cable insulation performance.

Description

technical field [0001] The invention relates to the technical field of cable processing and production, in particular to insulation extrusion equipment for cable production. Background technique [0002] A cable is usually a rope-like cable formed by twisting several or groups of wires, and often has the characteristics of internal energization and external insulation. [0003] During the production of cables, the outer insulating layer of the inner conductor is usually extruded. Through the melting and plasticization of the cable material, the molten cable material is extruded and wrapped on the inner conductor through the extruder head to form a cable. [0004] Extrusion is carried out by using extrusion equipment. Conventional extruders do not have the function of crushing cable materials. During the melting process of large particles of cable materials, there is often the problem of insufficient melting, and it is easy to mix solid particles, which seriously affects the ...
