Description

Technical Field

[0001] The utility model relates to the technical field of wire wrapping machine equipment, in particular to a concentric cable wire wrapping machine. Background Art

[0002] Cable is an electric energy or signal transmission device, usually composed of several or several groups of wires; after the single wire of the cable is processed, it is necessary to use a wire bundling machine to twist several single wires into a strand, and then put on an outer wrapping layer to achieve the wire bundling operation and prevent the cable from being loose. The outer layer is usually wound with insulating cloth. The work of completing the above outer layer wrapping often uses a concentric wire wrapping machine. The bracket of the wire wrapping machine places the reel of the insulating layer. With the rotation of the bracket and the movement of the cable, the insulating layer will gradually wrap around the outer wall of the cable; the wire wrapping machine currently used does not have a pressing function. Since the outer wall of the cable is not a smooth surface, after the insulating layer is wrapped around the outer wall of the cable, some areas are not tightly fitted with the insulating layer, and gaps will be left. This causes the insulating layer to be easily separated from the cable during subsequent transportation and delivery, affecting the quality of the cable. Based on the above problems, a concentric cable wire wrapping machine is proposed. Utility Model Content

[0016] A third bracket 16 is also installed at the top of the base 1. A through groove is provided at the top of the outer wall of the third bracket 16, and the cable can pass through the through groove. The through groove is coaxially arranged with the first through hole 8. The outer wall of the third bracket 16 is equidistantly arranged with a plurality of groups of limiting parts along the circumferential direction with the through groove as the center, wherein the limiting part includes a fixing block 17, and the fixing block 17 is fixedly installed on the outer wall of the third bracket 16. The outer wall of the fixing block 17 is screwed and penetrated by a screw 18. Rotating the screw 18 can make it move itself. An anti-slip block 19 is installed at one end of the screw 18 facing outward, which can facilitate the rotation of the screw 18 and prevent the screw 18 from detaching. A mounting seat 20 is rotatably installed at the other end of the screw 18. A pressing cylinder 21 is rotatably installed in the inner cavity of the mounting seat 20. The outer wall of the pressing cylinder 21 has an arc, which can fit with the outer wall of the cable. When the cable moves, the pressing cylinder 21 can follow the rolling, and the pressing cylinder 21 is used to press the cable insulation layer to make the insulation layer fit more closely.

[0017] As a preferred embodiment, further, a second bracket 14 is installed on the top of the base 1, and a cylinder 15 is installed on the top of the second bracket 14, and the cylinder 15 is coaxially arranged with the first through hole 8. The inner cavity of the cylinder 15 is spirally arranged with a heating wire, and the heating wire can generate heat after being connected to an external power supply. When the cable passes through the inner cavity of the cylinder 15, the insulating layer of materials such as rubber and PVC will shrink rapidly, thereby more tightly wrapping the outer wall of the cable.

[0018] The detailed connection means are well-known technologies in the art. Through the use of wires, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components complete the electrical connection in the order of working. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0019] When in use, a reel of the cable insulation layer is placed on the outer wall of the rotating shaft 7, and then the free end of the cable is passed through the outer wall of the outer shell 2, the second through hole 11, the first through hole 8, the third bracket 16 slot and the inner cavity of the cylinder 15, and the free end of each insulation layer reel is wound around the outer wall of the cable, and then the motor 9 is turned on to drive the second pulley 12 to rotate, and the first pulley 10 is rotated synchronously by the transmission of the belt 13, thereby driving the turntable 4 to rotate. At this time, each first bracket 5, the mounting plate 6 and the rotating shaft 7 follow the revolution, and the rotating shaft 7 itself can rotate, so that the insulation layer is wound around the outer wall of the cable. At this time, an external traction machine and other equipment can be used to pull the cable The cable can be wrapped by pulling. In addition, the screw rod 18 is rotated in advance to move it along the fixed block 17, so that the pressing cylinder 21 fits the cable. As the cable moves, the pressing cylinder 21 rolls and presses the insulating layer to fit the unbonded insulating layer to the cable. At the same time, the external power supply is started in advance to heat the electric heating wire on the inner wall of the cylinder 15. When the cable passes through the inner cavity of the cylinder 15, the insulating layer can be temporarily heated and contracted, thereby wrapping the cable. In actual use, not only can the automatic cable wrapping be achieved, but also the insulating layer of the unbonded cable can be pressed and fitted to avoid looseness in the later stage, and the insulating layer can be heated and contracted to tightly wrap the cable.
