Cable insulation layer coating machine

Abstract

The invention belongs to the cable processing field and especially discloses a cable insulation layer coating machine. The machine comprises a die. The die is provided with a glue flowing chamber connecting a plastic extruding machine discharge end. A line passing channel connected to the glue flowing chamber is arranged in the die. A glue scraping unit comprises a pedestal which is in a circulardisc shape and is rotatably connected to the die. The pedestal is fixedly provided with a circular-bench-shaped and hollow glue scraping seat whose upper end is a small diameter end. The side wall ofthe glue scraping seat is provided with several bar-shaped through holes which are along a circular bench bus direction and pass through the side wall of the glue scraping seat. A rolling unit is arranged above a glue scraping unit. The lower end of a first rotating disk is fixedly provided with a first motor used for driving a first sleeve to rotate. A paying-off unit is arranged below the die. Arack is rotatably connected to a rotating shaft and a second motor used for driving the rotating shaft to rotate. The rotating shaft is provided with a first driving gear and a second driving gear located below the first driving gear. In the scheme, a requirement of timely processing a redundant insulating glue solution on a copper wire during a coating process is satisfied.

Description

technical field [0001] The invention belongs to the field of cable processing, and in particular relates to a cable insulating layer coating machine. Background technique [0002] The basic structure of the cable mainly includes a copper wire and an insulating layer and a protective layer coated on the copper wire in turn. Among them, the function of the insulating layer is to avoid electric leakage during the use of the cable. The insulating layer coating of the prior art needs to pass through the extruder to make the raw material into a molten state, that is, to form an insulating glue, and then coat it through the cable insulating layer. The machine coats the insulating glue on the copper wire. [0003] The prior art cable insulation layer covering device includes a mold connected to the discharge end of the extruder, and the mold is provided with a flow glue chamber connected with the discharge end of the extruder and a wire passage connected with the flow glue chamber ...

AI Technical Summary

Problems solved by technology

The above-mentioned device has the following defects: 1. Due to the different extrusion pressures of the insulating glue in the wire-passing channel, it is difficult to completely cover the copper wires, resulting in that the outer diameter of the obtained insulating layer cannot match the inner diameter of the outlet end of the wire-passing channel. 2. The mold is fixed on one side of the extruder, and when the copper wire passes through the wire passage, it is still relative to the mold, and only one side of the copper wire in the wire passage is subjected to the extrusion pressure of the extruder. The wire will be twisted to the side away from the extruder, causing the copper wire to appear eccentric when sheathed
