Problems solved by technology

[0003] In the existing wire and cable gluing technology, the surface of the wire and cable is generally coated with insulation by dipping. This method of outsourcing insulation is inefficient, and the thickness of the coating is uneven, which is prone to core deviation.
There are also some straight-through rubber covering devices in the industry. The wire core is coated and insulated on the wire core through the through hole containing the insulating glue. The problem of different thickness of insulation layer

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] As shown in the figure, the automatic coating device for the insulation layer of wires and cables includes: a screw extruder 1, which is characterized in that: a rubber coating device 2 is provided at the glue outlet of the screw extruder 1, and the rubber coating The device 2 is fixedly connected to the screw extruder 1 through a bracket. The front and rear sides of the rubber covering device 2 are respectively provided with a wire release device 3 and a wire take-up device 4. The copper core of the cable is wound between the wire release device 3 and the wire take-up device. between the devices 4 and pass through the lagging device 2 at the same time.

[0023] Preferably, the encapsulation device 2 is composed of an encapsulation base body 21, a wire passing channel 22, a heater 23, a glue flow chamber 25 and a rubber scraping head 24, ...

Abstract

The invention discloses an automatic wrapping device of an insulation layer of a wire and cable. The automatic wrapping device of the insulation layer of the wire and cable comprises a screw extruder, and is characterized in that a rubber wrapping device is arranged at a rubber outlet of the screw extruder, the rubber wrapping device is fixedly connected with the screw extruder through a support, a paying off device and a taking up device are arranged on the front side and the rear side of the rubber wrapping device respectively, and a cable copper core is wound between the paying off device and the taking up device and penetrates through the rubber wrapping device. Pressure of liquid rubber is ensured by the adoption of the screw extruder, porous liquid rubber permeates and fills a cable passing channel, a front cable guide pipe and a rear cable guide pipe position the position of the copper core, a rubber scraper amends the insulation layer outside the wire and cable and controls the diameter of the insulation layer outside the wire and cable, the mode that the paying off device takes up the wire and cable in a damping mode is adopted so that the copper core can be located in the core portion of the wire and cable when wrapping the insulation layer, and it is ensured that the insulation wrapping of the wire and cable meets the use requirement. The insulation layer of the wire and cable is bright and clean in appearance, wire diameters are uniform, and the phenomena that a wire core deflects and insulation layers are not uniform in thickness are avoided.

Description

technical field [0001] The invention relates to a wire and cable production equipment, in particular to a wire and cable insulation layer automatic coating device. Background technique [0002] In general low-voltage wires and cables, in order to prevent accidents such as short circuit and leakage during use, the wire and cable production industry will uniformly and hermetically wrap a layer of non-conductive material around the wires, such as: resin, plastic, silicon, etc. Rubber, PVC, etc., form an insulating layer to prevent accidents such as leakage, short circuit, and electric shock caused by the contact between the conductor and the outside world. This kind of wire is called an insulated wire. [0003] In the existing wire and cable gluing technology, the surface of the wire and cable is generally coated with insulation by dipping. This method of outsourcing insulation is low in efficiency, and the thickness of the coating is uneven, which is prone to core deviation. ...
