Description

Technical Field

[0001] The utility model relates to the technical field of cable stranding machines, and particularly relates to a protective cable stranding machine. Background Technique

[0002] A cable stranding machine is a machine that twists two insulated wire cores into a telephone cable pair group, and is an electric wire and cable device applied to the stranding of high-frequency data cable wires, which twists multiple single conductors into one strand to meet the process requirements of the wire.

[0003] When the cable stranding machine is in use, the cable reel is placed on the stranding machine, and then the cable is wound around the guiding disk to guide the cable. The stranded cable after guiding passes through the through holes opened in the guiding plate. In order to better guide and position the stranded cable, the through holes are usually set to be smaller and lack a protection device. When the cable quickly passes through the through holes, if it accidentally rubs against the through holes, it is easy to damage the surface of the cable. Therefore, a protective cable stranding machine is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a protective cable stranding machine to solve the problem that the surface of the cable is easily damaged if it accidentally rubs when passing through the through holes quickly.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A protective cable stranding machine includes a stranding machine main body for stranding two cables into a strand, a guiding disk for guiding the cable, and a support frame for supporting the guiding disk. The stranding machine main body includes a feeding device and a winding device. One side of the feeding device is fixedly connected with a support frame composed of a plurality of cross bars and vertical bars. There are a plurality of guiding disks on one side of the support frame. There is a winding device on one side of the feeding device. One side of the winding device is fixedly connected with a fixed rod. A moving block slides on the outside of the fixed rod. One side of the moving block is fixedly connected with a guiding plate. A plurality of through holes are opened in the middle of the guiding plate. An installation component and a wear-resistant component are arranged in the through holes opened in the guiding plate. The installation component includes a rubber ring and a rubber sleeve. The rubber sleeve is closely fitted in the through holes opened in the guiding plate. The wear-resistant component includes a wear-resistant layer, rubber blocks and elastic blocks. The wear-resistant layer which is flexibly arranged is closely fitted in the rubber sleeve.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0022] A protective cable stranding machine includes a stranding machine main body 1 for stranding two cables into strands, a guiding disk 3 for guiding the cables, and a support frame 2 for supporting the guiding disk 3. The stranding machine main body 1 includes a feeding device 101 and a winding device 102. One side of the feeding device 101 is fixedly connected to a support frame 2 composed of a plurality of cross bars and vertical bars. There are a plurality of guiding disks 3 on one side of the support frame 2. There is a winding device 102 on one side of the feeding device 101. One side of the winding device 102 is fixedly connected to a fixed rod 4. A moving block 5 slides on the outside of the fixed rod 4. One side of the moving block 5 is fixedly connected to a guiding plate 7. A plurality of through holes 8 are opened in the middle of the guiding plate 7. An installation component 10 and a wear-resistant component 9 are provided in the through holes 8 opened in the guiding plate 7. The installation component 10 includes a rubber ring 1001 and a rubber sleeve 1002. The rubber sleeve 1002 is closely fitted in the through holes 8 opened in the guiding plate 7. The wear-resistant component 9 includes a wear-resistant layer 901, a rubber block 902, and an elastic block 903. The wear-resistant layer 901 which is flexibly arranged is closely fitted in the rubber sleeve 1002. By arranging the wear-resistant component 9 and the installation component 10 in the through hole 8, a protection component is provided in the through hole 8 to effectively protect the stranded cables passing through. Through the detachable structure arranged for the wear-resistant component 9 and the installation component 10, it is convenient to replace them after long-term use.

[0023] Both the left and right ends of the rubber sleeve 1002 are fixedly connected with rubber rings 1001. The outer diameter of the rubber ring 1001 is larger than that of the rubber sleeve 1002, which is convenient for the installation of the installation component 10. A number of rubber blocks 902 are fixedly connected to the outside of the wear-resistant layer 901. The front and rear sides of the rubber blocks 902 are convexly arranged outward. Elastic blocks 903 are arranged inside the rubber blocks 902, which is convenient for the replacement of the wear-resistant layer 901. A number of grooves 11 are formed in the rubber sleeve 1002. The grooves 11 formed in the rubber sleeve 1002 are closely fitted with the rubber blocks 902, which is convenient for the fixation of the wear-resistant layer 901. A scale 12 is arranged on the surface of the fixed rod 4, and a hand-tightening bolt 6 for fixation is arranged on the outside of the moving block 5, which is convenient for the precise movement of the moving block 5.

[0024] Working process: When the protective cable stranding machine is in use, first place the main body 1 of this stranding machine in a suitable position, place the two cables to be stranded in the feeding device 101, and the two cables bypass the guide disc 3. The stranded cable passes through the through hole 8 formed in the guide plate 7 and then enters from the feeding port of the winding device 102. Since the installation component 10 is arranged in the through hole 8 and the wear-resistant layer 901 is arranged in the installation component 10, during the winding process, the stranded cable quickly passes through the wear-resistant layer 901, effectively protecting the outer surface of the cable, so that its outer side is not easily damaged by friction. When the wear-resistant layer 901 needs to be replaced after long-term use, since the wear-resistant layer 901 is flexible, the user directly holds the wear-resistant layer 901 and tears off its upper half from the rubber sleeve 1002. The rubber block 902 disengages from the groove 11 formed in the rubber sleeve 1002, and then tears off the lower half of the wear-resistant layer 901 in the same way. At this time, the wear-resistant layer 901 can be moved to the right and taken out. Then place a new wear-resistant layer 901 in the rubber sleeve 1002, align the rubber block 902 with the groove 11 and insert it. After insertion, the elastic block 903 increases the overall elasticity of the rubber block 902, making it more stable after insertion. When the elasticity of the rubber sleeve 1002 decreases after long-term use and needs to be replaced, the user first disassembles the wear-resistant component 9, and then removes the rubber ring 1001 and the rubber sleeve 1002 as a whole from the through hole 8. Then, a new installation component 10 is stuffed into the through hole 8 and fixed by its own elasticity. By arranging the wear-resistant component 9 and the installation component 10 in the through hole 8, a protective component is provided in the through hole 8 to effectively protect the stranded cable passing through. Through the detachable structure arranged on the wear-resistant component 9 and the installation component 10, it is convenient for replacement after long-term use.
