Technical Field

[0002] Wires are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. Wires and cables are also referred to as cables, one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors. The service life of wires and cables is directly related to the quality of their insulation layer. The insulation layer of wires and cables is formed by melting solid plastic and wrapping it on the outer surface of wires and cables through an injection molding machine and an extrusion device. The insulation layer of the wire can provide a good working environment for the wire and protect the internal structure of the wire. It needs to be formed by a special extruder.

[0003] At present, during the traditional extrusion process of wire insulation layer, the solid plastic is not convenient for the wire conductor to fully contact after melting, which makes it difficult for the molten material to be evenly wrapped on the surface of the wire conductor, resulting in poor quality of the wire insulation layer extrusion process, affecting the subsequent use of the wire.

[0022] 7. The wire insulation layer extrusion processing device uses a suction fan to suck out the hot air in the insulation cylinder, and under the transportation of the zigzag pipe, the hot air enters the airway and is discharged from the exhaust hole, so that the hot air is sprayed toward the conductor between the first round roller and the second round roller, so as to preheat the conductor, fully connect the structure together, and recover and reuse the heat.

[0032] By passing the conductor coated with material through the center of the conical extrusion cover 425, and by making the conical extrusion cover 425 conical so that the diameter of the conical extrusion cover 425 gradually decreases, the liquid material on the surface of the conductor can be squeezed so that the liquid material fully contacts the surface of the conductor.

[0036] The third embodiment, as Figure 1-Figure 8 As shown, based on the first and second embodiments: A pretreatment component 5 is installed at the top of the frame 1 and at one end away from the insulation box 421. The pretreatment component 5 includes a support frame 51, which is fixed to the top of the frame 1 and at one end away from the insulation box 421 by screws. A connecting ring 52 is fixedly installed on the top of the support frame 51, and a supporting circular cylinder 53 is rotatably installed in the middle of the inner side of the connecting circular ring 52.

The U-shaped toggle rod 36 contacts the force-bearing right-angle rod 54. As the U-shaped toggle rod 36 continues to rotate, and combined with the meshing installation between the U-shaped toggle rod 36 and the force-bearing right-angle rod 54, the force-bearing right-angle rod 54 is subjected to the toggle force of the U-shaped toggle rod 36, and with the support of the supporting frame 51 and the connecting ring 52 on the supporting circular cylinder 53, the supporting circular cylinder 53 is rotated, and the wiping strip 55 can be driven to rotate, so that the rotating wiping strip 55 can be used to wipe the surface of the conductor.

As the U-shaped toggle rod 36 continues to rotate, and the U-shaped toggle rod 36 and the stressed right-angle rod 54 are meshed and installed, the stressed right-angle rod 54 is subjected to the toggle force of the U-shaped toggle rod 36, and under the support of the supporting frame 51 and the connecting ring 52 on the supporting circular cylinder 53, the supporting circular cylinder 53 is rotated, and the wiping strip 55 can be driven to rotate, so that the conductor surface is wiped by the rotating wiping strip 55; The staff turns on the injection molding machine 41 to work.

As the conductor continues to move, the surface of the conductor can be continuously coated. As the liquid material is applied to the surface of the conductor, the liquid material applied to the surface of the conductor moves together with the movement of the conductor, and the liquid material can be contacted with the scraper 426 to scrape the liquid material, so that the liquid material is evenly applied to the surface of the conductor; By passing the conductor coated with material through the center of the conical extrusion cover 425, and by making the conical extrusion cover 425 conical so that the diameter of the conical extrusion cover 425 gradually decreases, the liquid material on the surface of the conductor can be squeezed so that the liquid material fully contacts the surface of the conductor.
