Description

Technical Field

[0001] The utility model relates to the technical field of cable manufacturing, in particular to a cable extrusion and taping integrated series machine. Background Technique

[0002] The 224G PICE6.0 supporting cable is widely used in the AI field. When used for internal transmission, its market demand is very large, and thus the production efficiency of the corresponding cable needs to be improved. However, in the existing production equipment, the cable needs to go through FEP-filled double-conductor extrusion during the production process. Since the FEP material has too low viscosity during use, in the tube extrusion process, due to the large glue outlet area, the material can only be produced at a low flow rate, resulting in a relatively low production efficiency; when using the extrusion method for production, due to the small glue outlet area, the material is produced at a high flow rate. In this state, due to the too fast flow rate, problems such as turbulent flow and stratification will occur during rapid extrusion, so the defect of slow FEP extrusion speed cannot be solved at the material level for the time being.

[0003] After the existing cable is extruded and formed, the semi-finished product needs to be placed, and then transferred to an independent wrapping and winding station for further operation. In the actual use process, independent traction systems, pay-off systems, and winding systems need to be set for both the extrusion and forming and the wrapping and winding mechanisms, which makes the cable manufacturing process relatively complex. Therefore, there is an urgent need to develop a cable manufacturing equipment that can reduce the process and equipment costs. Summary of the Invention

[0004] In view of the above problems, the utility model provides a cable extrusion and taping integrated series machine, which integrates insulation extrusion and wrapping on one production line, shares the traction system, pay-off system, and winding system, saves processes, reduces labor costs and equipment costs, and improves the production efficiency of the cable.

[0005] A cable extrusion and taping integrated series machine, characterized in that it includes:

[0006] A pay-off system, which is a double-head power pay-off system;

[0007] An extrusion system;

[0008] A cooling system;

[0009] A traction system;

[0010] A wrapping combination system;

[0011] And a winding system;

[0012] The wire feeding system, extrusion system, cooling system, traction system, wrapping combination system, and wire winding system are arranged in a straight line in sequence. After the wire feeding system outputs two conductors, they enter the head of the extrusion system, and are extruded and coated with FEP material through the head. After being cooled by the cooling system, they are pulled by the traction system to the entrance of the wrapping combination system at the rear. After being wrapped by the wrapping combination system, they flow out, and finally are wound by the wire winding system.

[0013] Its further features are as follows:

[0014] The cooling system is an air-cooling system, which occupies a small volume, has a simple structure compared with water-cooling, and has a high cooling efficiency compared with natural cooling;

[0015] An XY-axis eccentric adjustment platform is arranged behind the air-cooling system. The XY-axis eccentric adjustment platform is used to adjust the eccentric position, that is, the offset of the two conductors in the FEP insulation, to ensure that the appearance eccentricity of the core wire extruded with FEP material led out by the subsequent traction system meets the design standard;

[0016] A detection station for the core wire size and appearance eccentricity is integrated at the core wire outlet position of the traction system. After manually intercepting a section of the core wire at this station for detection, if the detection is qualified, the core wire flowing out of the traction system directly flows to the entrance of the wrapping combination system for subsequent wrapping operations. If the core wire intercepted at this station is detected to be unqualified, the front-end XY-axis eccentric adjustment platform is adjusted until the eccentric position of the conductor meets the design requirements, and then the core wire flows to the entrance of the wrapping combination system;

[0017] The wrapping combination system includes a longitudinal wrapping system, a first wrapping system, a second wrapping system, and a heating system arranged in sequence. The longitudinal wrapping system is used to longitudinally wrap the first metal layer on the outer periphery of the insulating layer. The first wrapping system is used to wrap the second metal layer on the outer periphery of the first metal layer. The second wrapping system is used to wrap the mylar on the outer periphery of the second metal layer. The heating system is used to adhere the inner layer of the mylar to the outer periphery of the second metal layer;

[0018] The wire winding system is an axial row wire winding machine.

[0019] After adopting the above technical solution, when operating this equipment, it is divided into two parts:

[0020] The first part: The wire feeding system releases two conductors. The two conductors are extruded and coated with FEP material through the head to form insulation, and then are cooled by the cooling system. The core wire pulled out by the traction system can detect design requirements such as the core wire size and appearance eccentricity. Up to the traction system as a node, the debugging waste wire can be directly scrapped here and not enter the subsequent equipment. When it is confirmed that the first-piece inspection is qualified, the second part is implemented;

[0021] In the second part, the qualified core wires are passed through each group of systems in the wrapping combination system and then connected to the take-up machine. While the wires are being routed, the wrapping tapes for the spacer layers are gradually assembled.

[0022] The above two parts can be operated independently or combined in a linkage process. It integrates insulation extrusion and wrapping on one production line, sharing the traction system, wire feeding system, and take-up system, saving processes, labor costs, and equipment costs, and improving the production efficiency of cables.

[0028] A cable extrusion and wrapping integrated tandem machine, as shown in Figure 1 , which includes a wire feeding system 1, an extrusion system 2, a cooling system, a traction system 5, a wrapping combination system, and a take-up system 10;

[0029] Specifically, the wire feeding system 1 is a double-head power wire feeding system;

[0030] The cooling system is an air cooling system 3, which occupies a small volume, has a simple structure compared to water cooling, and has a high cooling efficiency compared to natural cooling. An XY-axis eccentric adjustment platform 4 is arranged behind the outlet of the air cooling system 3. The XY-axis eccentric adjustment platform 4 is used to adjust the eccentric position, that is, the offset of the two conductors 101 in the FEP insulation 102, to ensure that the appearance eccentricity of the extruded core wire with FEP material derived by the subsequent traction system 5 meets the design standard;

[0031] The traction system 6 is equipped with a power adjustment mechanism and a guiding mechanism;

[0032] The wrapping combination system includes a longitudinal wrapping system 6, a first wrapping system 7, a second wrapping system 8, and a heating system 9 arranged in sequence;

[0033] The wire feeding system 1, extrusion system 2, air cooling system 3, XY-axis eccentric adjustment platform 4, traction system 5, longitudinal wrapping system 6, first wrapping system 7, second wrapping system 8, heating system 9, and wire winding system 10 are arranged in sequence in a straight line. The wire feeding system 2 outputs two conductors and then enters the head of the extrusion system 3. After being extruded by the head, an FEP material is coated. After being cooled by the air cooling system 3, it passes through the XY-axis eccentric adjustment platform 4, and then is pulled by the traction system 5. At the core wire outlet position of the traction system 5, there is an integrated inspection station for the size, appearance, and eccentricity of the core wire (not shown in the figure, only a single-operator station needs to be accommodated here). After manually intercepting a section of the core wire at this station for inspection, if the inspection is qualified, the core wire flowing out of the traction system 5 directly flows to the inlet of the wrapping combination system for subsequent wrapping operations. If the core wire intercepted at this station fails the inspection, the XY-axis eccentric adjustment platform 4 at the front end is adjusted until the eccentric position of the conductor meets the design requirements, and then the core wire passes through the longitudinal wrapping system 6, first wrapping system 7, second wrapping system 8, heating system 9 in sequence, and finally is wound by the wire winding system 10.

After that, they are cooled by the air cooling system 3. The core wire pulled out by the traction system 5 can be inspected for design requirements such as the size, appearance, and eccentricity of the core wire. Up to the traction system 5 as a node, the debugging waste wire can be directly scrapped here and not enter the subsequent equipment. When it is confirmed that the first-piece inspection is qualified, the second part is implemented;

[0036] The second part: The qualified core wire is passed through each system in the wrapping combination system and then connected to the wire winding machine 10. While the wire is passing, the spacer tapes are gradually assembled.

[0037] The above two parts can be operated independently or combined in a linkage process. It integrates insulation extrusion and wrapping on one production line, sharing the traction system, wire feeding system, and wire winding system, saving processes, labor costs, and equipment costs, and improving the production efficiency of cables.

A first aluminum foil layer 103, a second aluminum foil layer 104, and a mylar wrapping layer 105 are sequentially wrapped around the outer periphery of the insulation 102. The two processing parts are respectively: 1. Insulation extrusion, Figure 2 In this step, the middle conductor 101 and the insulation 102 part are completed; 2. Tape winding (two layers of aluminum foil + one layer of mylar are completed in this process). Using a cable extrusion and taping integrated series machine to combine the two steps, the generation of defective products is reduced, and the possibility of semi-finished product stagnation is eliminated. The specific process of processing through the integrated series machine is as follows:

[0040] S1. The double-head pay-off machine releases two independent conductors 101;

[0041] S2. The extrusion system 2 extrudes and coats with FEP material to form insulation 102;

[0042] S3. The air-cooling system 3 completes the cooling of the insulation 102;

[0043] S4. The XY-axis eccentric adjustment platform 4 is used to adjust the offset of the conductor 101 in the insulation 102;

[0044] S5. The traction system 5 provides power, and employees can cut the wire and detect and adjust the size of the insulation structure and the offset of the conductor 101 in the insulation 102;

[0045] S5. The longitudinal wrapping system completes the longitudinal wrapping of the first aluminum foil layer 103, so that the first aluminum foil layer 103 is longitudinally wrapped around the outer periphery of the insulation;

[0046] S6. The first wrapping system wraps to form the second aluminum foil layer 103;

[0047] S7. The second wrapping system wraps to form the mylar wrapping layer 104;
