[0027] A forming device for insulated composite wires and cables, according to Figure 1 As shown, the molding device includes an extrusion device 1 and a composite device 2. The extruder attaches and forms an insulation layer on the outer layer of the core wire of the wire and cable. The insulation layer is made of heat-resistant and corrosion-resistant polyvinyl chloride composite material. The discharge end of the extrusion device 1 wraps the copper core wire with the insulation layer, which has excellent insulation effect. The extrusion device 1 heats the polyvinyl chloride composite material, and then through the extrusion process, the molten polyvinyl chloride composite material is successfully wrapped around the outside of the core wire of the wire and cable, and then cooled to form an insulation layer.

[0028] Among them, polyvinyl chloride composite materials can be recycled and reused using plastic solid waste from wire stripping and recycling, which reduces costs and promotes green and environmentally friendly production.

[0029] The extrusion equipment 1 is located on the side of the composite device 2, and the outlet end of the extrusion equipment 1 faces the feed end of the composite device 2.

[0030] according to Figure 2 As shown, a wire-cutting assembly is installed on one side of the feed end of the composite device 2, and a wire-parallel assembly and a composite assembly are installed on one side of its discharge end, with the composite assembly located on one side of the wire-parallel assembly.

Then, through several belts 22, multiple transmission belt rollers 21 are driven to rotate synchronously.

[0033] Furthermore, a cylinder 26 is fixedly installed on the composite device 2. The output end of the cylinder 26 is set upward, and a pressure frame is fixedly connected to its output end. Two pressure claw assemblies 27 are symmetrically installed on the pressure frame. The two pressure claw assemblies 27 are arranged sequentially along the conveying direction of the conveyor belt 23 and are located on both sides of the pressure frame. Both ends of the pressure claw assembly 27 are provided with elastic plates 28. The two ends of the pressure claw assembly 27 cooperate with the positioning groove 25 to accurately connect the two ends of the wire seat 24. At this time, the elastic plates 28 are located inside the wire seat 24, pressing the insulated composite wire and cable placed inside the wire seat 24. However, the wire and cable on the wire seat 24 located between the two pressure claw assemblies 27 are not fixed.

[0034] according to Figure 3 As shown, the wire cutting assembly includes a horizontal seat 3, on which a second cylinder 31 is fixedly mounted. A top plate 32 is fixedly connected to the output end of the second cylinder 31. Round shafts 33 are welded to both ends of the top plate 32. Symmetrically distributed swing rods 34 are rotatably mounted above the second cylinder 31. A slanted groove 35 is provided in the middle of the swing rod 34. The slanted groove 35 is slidably connected to the round shaft 33. The end of the round shaft 33 passes through the slanted groove 35 and is connected to a nut to limit the lateral displacement of the swing rod 34. At the same time, a cutting blade 36 is fixedly mounted on the top of the swing rod 34.

[0035] The top plate 32 is moved upward by the cylinder 31, and the circular shaft 33 moves upward in the inclined groove 35, so that the two swing rods 34 rotate along their connecting mounting shaft. The two swing rods 34 rotate towards each other, and the cutting blades 36 move closer to each other, cutting the molded insulated composite wire and cable that passes above the cutting blades 36 into wire bundles.

A round block 453 is provided on the inner side of the boss 451, and a wire clamping groove 452 is opened on the top of the boss 451 to move the wires located on both sides.

[0039] Among them, the racks on the two moving rods 45 are symmetrically arranged around the axis of the gear 431 and mesh with the gear 431 at the same time. When the gear 431 rotates, it will drive the two moving rods 45 to move towards or away from each other, so as to change the distance between the two bosses 451.

[0040] A V-groove seat 49 is provided in the middle of the movable plate 42. The V-groove seat 49 is aligned with the aforementioned unfixed wires and cables and supports the wire harness. The two wires and cables on both sides of the V-groove seat 49 cooperate with the wire clamping groove 452. The wire clamping groove 452 moves the wire ends of the two sides to the side of the V-groove seat 49 and close to the position of the V-groove seat 49.

[0041] A notch 47 is provided at the end of the V-groove seat 49 away from the conveyor belt 23, and support rods 48 are provided on both sides of the notch 47. The ends of the support rods 48 are provided with an upper chamfer. When the wire clamping groove 452 pushes the wire and cable to both sides of the V-groove seat 49, in order to prevent the wire and cable from shifting downward, the support rods 48 support the wires on both sides to prevent the wire and cable from sliding down.

[0042] according to Figure 10 , Figure 11 , Figure 12As shown, the composite component includes a fixed plate 5, on which an electric slide 51 is provided. The electric slide 51 is a linear slide module, and a mounting frame 52 is provided on the electric slide 51. The mounting frame 52 is driven to move horizontally by the linear slide module.

[0043] Several through holes 58 are provided on the plate 57. U-shaped frame 1 59 and U-shaped frame 2 50 are slidably arranged in the through holes 58. The structure of U-shaped frame 2 50 is smaller than that of U-shaped frame 1 59, and U-shaped frame 2 50 is located inside U-shaped frame 1 59. Springs 500 are fixedly connected to the inner side of U-shaped frame 2 50 and U-shaped frame 1 59. Springs 500 support U-shaped frame 2 50 and U-shaped frame 1 59 and maintain their height.

[0044] A convex shaft 2 501 is fixedly provided on the side of U-shaped frame 2 50, and a convex shaft 1 591 is fixedly provided on the side of U-shaped frame 1 59. In the static state, convex shaft 1 591 and convex shaft 2 501 are located on the horizontal plane. At this time, the lower ends of U-shaped frame 2 50 and U-shaped frame 1 59 are flush with the lower surface of plate 57. A motor 3 56 is fixedly connected to the movable frame 54 by bolts. The output end of motor 3 56 is connected to a swing arm 561.

[0045] When the swing arm 561 rotates to one side, it presses down on the second convex shaft 501. At this time, the lower end of the first U-shaped frame 59 protrudes downward through the through hole 58, pressing the plastic wrapping material 61 after the wires are connected between the two wires and cables, wrapping and fixing the wires and cables. When the swing arm 561 rotates to the other side, it presses down on the first convex shaft 591. At this time, the lower end of the second U-shaped frame 50 bends the excess plastic wrapping material 61 at both ends, placing it outside the outermost wire and cable. After the temperature cools down, the shape of the plastic wrapping material 61 is fixed. At this time, the plastic wrapping material 61 is like... Figure 12 As shown, three insulated composite wires and cables are connected in parallel and fixed.

[0046] At work; The copper core of the wire and cable is prepared in advance and then fed into the extruder. The extrusion equipment 1 heats the polyvinyl chloride composite material, and then through the extrusion process, the molten polyvinyl chloride composite material is successfully wrapped around the outside of the core of the wire and cable, and then cooled to form an insulation layer.

[0047] The formed insulated composite wires and cables pass over the wire-cutting assembly and enter the conveyor belt 23, where they are placed on the wire holder 24. The wire-cutting assembly cuts the wires, and then the conveyor belt transports the wires to the processing position of the composite assembly. Two... First, the plate 57 moves towards the V-groove seat 49, pushing the unfixed end of the wire and cable in the middle to move backward, so as to align with the ends of the wire and cable after they are paralleled on both sides. At this time, the heating module set on the side of the metal stand 41 heats the plastic packaging material 61 and softens the plastic packaging material 61.

[0048] The heating module is existing technology and will not be described in detail here.

[0049] After heating, the plate 57 is moved upwards, first removing it from the heated position, and then the plate 57 is gradually moved above the notch 47. The electric slide 53 drives the plate 57 to move above the notch 47. The plate 57 moves until the plastic packaging material 61 is above the three wires and cables. At this point, the motor 56 is started to drive the subsequent bending process of the plastic packaging material 61, as follows: When the swing arm 561 rotates to one side, it presses down on the second convex shaft 501. At this time, the lower end of the first U-shaped frame 59 protrudes downward through the through hole 58, pressing the plastic wrapping material 61 after the wires are connected between the two wires and cables, wrapping and fixing the wires and cables. When the swing arm 561 rotates to the other side, it presses down on the first convex shaft 591. At this time, the lower end of the second U-shaped frame 50 bends the excess plastic wrapping material 61 at both ends, placing it outside the outermost wire and cable. After the temperature cools down, the shape of the plastic wrapping material 61 is fixed. At this time, the plastic wrapping material 61 is like... Figure 12 As shown, three insulated composite wires and cables are connected in parallel and fixed.

[0050] Then, all mechanisms are in compliance, and the insulated composite wire and cable moves to the discharge end of the conveyor belt 23. After discharge, the wire seat 24 gradually moves to the feed end, thus continuously completing the extrusion, production, forming, and paralleling operations of the insulated composite wire and cable, with a high degree of automation.
