Cable extruder

Abstract

The invention relates to the technical field of wires and cables, and discloses a cable extruder. The cable extruder comprises a machine body, wherein a feeding port is fixedly formed in the top of the machine body; a machine head is fixedly arranged on the front surface of the machine body; a motor is fixedly arranged on the back surface of the machine body; an extrusion sleeve positioned in themachine body is fixedly arranged at the bottom of the feeding port through a feeding port; a rotating shaft is movably sleeved with the extrusion sleeve; a honeycomb plate is fixedly arranged on the front surface of the extrusion sleeve; a cooling water outlet pipe and a cooling water inlet pipe are fixedly arranged on the two sides of the bottom of the machine head correspondingly; a spiral waterpipeline is arranged in the machine head; and a scraping head is movably arranged on the extrusion sleeve. According to the cable extruder, the scraping head with a spring is arranged in the extrusion sleeve, so that the situation of dead glue coke materials is effectively reduced, and the production efficiency is improved; and the spiral cooling water pipeline is arranged in an extrusion table of the machine head, so that the extrusion quality of the cable is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a cable extruder. Background technique [0002] Cable extruder is a kind of equipment suitable for extruding wire and cable cores. It is composed of pay-off machine, tension group, main engine, main control cabinet, cooling water tank, traction machine, spark machine, wire take-up machine and other equipment. The most important The most important is the host, which needs to retaliate the wire core and cover the plastic insulation layer, and the host is at the front end of the whole process, so it has a great impact on the latter, so the requirements for the host of the cable extruder are also high. The existing The host uses the screw to extrude the plastic in the extrusion sleeve, and then extrudes it onto the cable core from the head part, but there will be the following problems in the use of the host: [0003] 1. Because there is a heating and melting section at one...

AI Technical Summary

Problems solved by technology

[0003] 1. Because there is a heating and melting section at one end in the extruding sleeve of the main engine, the plastic is melted into a molten state by high temperature heating, and there is a large temperature difference at the critical part between the feeding section and the heating section, so that on the screw The corresponding parts are easily adhered and solidified by the molten plastic to form dead rubber coke. On the one hand, this unusable dead glue coke will be squeezed out to cover the wire core under the condition of continuous feeding. The produced cables do not meet the requirements. On the other hand, some dead rubber coke solidifies on the helical leaves of the screw, which will cause blockage and affect the extrusion speed of the plastic, thereby further affecting the production efficiency. Regular cleaning of the screw is also a problem. It is a waste of time and manpower, and also has a great impact on production efficiency

[0004] 2. The plastic coated on the cable coming out of the machine head is made of molten plastic, and it takes a certain distance for the cable to come out of the machine head to the cooling water tank, so the plastic coated on the cable just coming out of the machine head It is still relatively soft, and it is easy to shift downward under the action of gravity, which will cause the thickness of the cable's outer covering plastic to be different, which is not conducive to subsequent use
