A wrapping device for insulating and fireproof layers of electric wires and cables

Abstract

The invention discloses a wrapping device for insulating and fireproof layers of electric wires and cables, which comprises a load-bearing plate, and a plurality of equiangularly distributed support columns are fixedly connected to the top outer wall of the load-bearing plate, and the top outer wall of the support column is fixedly connected with The lower ring groove block, and the inside of the lower ring groove block is provided with a second rotating gear, and the top outer wall of the second rotating gear is fixedly connected with a second placement block, and the top outer wall of the second placement block is fixedly installed with a plurality of etc. For the second placement frame with angular distribution, an upper ring groove block is arranged above the lower ring groove block. The motor provided in the present invention operates, and the gear meshing transmission drives the second placing frame on the second placing block to rotate around the central axis of the lower ring groove block, so that the fireproof material set on the second positioning rod is wrapped around the wire and cable. Outside the insulating layer; the insulating material is wound on the outer wall of the wire and cable; the rotation direction of the first rotating gear and the second rotating gear is opposite, which is beneficial to avoid the phenomenon that the same direction is easy to loosen.

Description

technical field [0001] The invention relates to the technical field of wire and cable production and processing equipment, in particular to a wrapping device for insulating and fireproof layers of wires and cables. Background technique [0002] Wires and cables are widely used in all walks of life. For example, household appliances need to be powered by wires. Usually, the wire consists of two parts. The plastic insulating sheath wraps the copper or aluminum core inside, and the outer sheath is to protect the inner core from mechanical damage. Wires and cables are manufactured through three processes: drawing, twisting, and covering. The more complex the model specification, the higher the repeatability. The coating is to wrap a layer of insulating material on the wire core.

Problems solved by technology

[0003] In the existing automatic coating device for the insulating layer, since the plastic material in the molten state is easy to dissipate heat in the flowing state, resulting in poor final coating effect, a heating mechanism is generally installed outside the rubber inlet pipe to avoid the temperature from affecting the coating effect. Another method is to wrap the insulating fireproof strip on the outer wall of the wire and cable, and rotate the wire and cable to achieve the purpose of winding, but the heating mechanism in the prior art is inconvenient to maintain and install. Once the heating tube burns out, It will greatly affect the processing efficiency of wires and cables; when winding, a large power electric drive device is required to drive the cable to rotate, and the production cost is high
