Description

Technical Field

[0001] The present invention relates to a multi-core wire cutting device, which is used to cut the insulation layer of multiple wire cores after the outer sheath is stripped. The present invention also relates to a multi-core cable stripping system including the multi-core wire cutting device, which performs the processes of cutting and stripping the insulation layer of multiple wire cores to complete the stripping work. Background Art

[0002] Generally speaking, the service life of wires and cables is usually 70 years. After reaching the service life, they need to be replaced. The old cables that are replaced need to have their sheath, insulation layer and conductor stripped and classified for recycling. Existing cable stripping equipment can only strip one layer of insulation at a time. If the cable is a multi-core insulation plus cable outer sheath structure, then it is necessary to strip the outer sheath of the cable first, then split the multi-core twisted structure inside the sheath, and finally strip the insulation layer of each core in turn. For example, to strip a five-core twisted cable, it is necessary to strip the cable six times separately, which is time-consuming and labor-intensive, and has low efficiency, affecting the classification and recycling of cables.

[0003] On the other hand, in order to reduce the cross-sectional area of ​​the cable, multi-core cables are generally designed as a whole round structure with each single-core cable as a special-shaped structure. However, the existing cable stripping equipment is designed for round single-wire stripping mechanisms. When stripping special-shaped wire cores, the wire cores will continue to twist at the stripping blade because the wire cores have a certain torque after being split. The wire core shape is not round, which causes the blade to not be in good contact with the cable insulation, resulting in poor stripping effect. If the contact point between the special-shaped cable and the stripping blade is fixed, the cable's own torque will continue to accumulate in the unwinding section, eventually breaking the cable and making it impossible to continue stripping. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a multi-core wire cutting device, which can cut the insulation layer of each core of a multi-core twisted cable at one time. The present invention also relates to a multi-core cable stripping system comprising the multi-core wire cutting device.

[0005] In order to solve the above technical problems, the multi-core wire cutting device of the present invention comprises a first wire cutting disc and a second wire cutting disc, wherein the first wire cutting disc and the second wire cutting disc are connected together, and there is a gap between the first wire cutting disc and the second wire cutting disc, and the first wire cutting disc and the second wire cutting disc have a central hole in the center of the first wire cutting disc and the second wire cutting disc through which the cable (the cable to be stripped of the wire core insulation layer) passes. The gap is used to place an adjustment rod, and the adjustment rod can move in the gap to achieve the adjustment rod being placed in an appropriate working position.

[0006] The first cleat disk has at least one arc-shaped slideway, and the first cleat disk has at least one notch, one notch corresponding to one arc-shaped slideway; the gap between the first cleat disk and the second cleat disk has at least one adjusting rod, the head end of the adjusting rod extends out of the first cleat disk and the second cleat disk, the end of the adjusting rod is connected to a cutting wheel, the cutting wheel is located in the center hole, the circumferential surface of the cutting wheel has a groove, the groove has an annular cutting knife, when the wire core is located in the groove, the annular cutting knife cuts the insulation layer of the wire core; the arc-shaped slideway has a fixing rod, the head end of the fixing rod has an adjusting thread outside the first cleat disk, and an adjusting nut is arranged on the adjusting thread; the end of the fixing rod has a fixing block, the fixing block is located in the gap between the first cleat disk and the second cleat disk; the inside of the adjusting rod has an adjusting chamber, the surface of the adjusting rod has an opening, the fixing block enters the adjusting chamber from the opening, and the adjusting chamber is larger than the fixing block, so that the height of the adjusting rod can be adjusted when the fixing block is not moving. When the position of the fixed block in the adjustment chamber corresponds to the position of the opening, the fixed block of the fixed rod can be taken out or put in from the opening; when the position of the fixed block in the adjustment chamber is misaligned with the position of the opening, the fixed rod is connected to the adjustment rod. After the fixed rod is connected to the adjustment rod, the adjustment nut can be adjusted to fasten the adjustment rod to the first cutting disc, thereby fixing the position of the adjustment rod, that is, fixing the position of the annular cutting knife. When adjusting the position of the adjustment rod, the fixed rod follows the adjustment rod to adjust the position in the arc-shaped slideway, and the annular cutting knife realizes the transformation of different positions.

[0007] When the adjusting rod needs to be taken out, the fixing rod only needs to be passed through the arc-shaped slideway, and the adjusting rod and the fixing rod are taken out as a whole through the notch. When the adjusting rod needs to be added, the adjusting rod is directly put into the gap, the fixing rod is placed into the arc-shaped slideway through the notch, and then the fixing rod is connected with the adjusting rod.

[0008] The wire cores are twisted together. When the cable is transported, the wire cores do not rotate. In order to achieve continuous cutting, the annular cutting knife needs to rotate and always correspond to the wire core it cuts. The first cutting disc or the second cutting disc is rotatably mounted on the bracket. When the cable is transported, the wire cores do not rotate, and the first cutting disc and the second cutting disc rotate with the wire core. In order to reduce resistance, the first cutting disc or the second cutting disc is connected to the inner ring of the bearing, the outer ring of the bearing is mounted on the bracket, and the inner ring of the bearing is driven to rotate by a power device (such as a motor).

[0009] The arc-shaped slideways are evenly distributed on a circumference and have the same distance from the central hole.

[0010] The first cutting wire disc and the second cutting wire disc are connected together through a partition. The existence of the partition forms a gap between the first cutting wire disc and the second cutting wire disc.

[0011] The multi-core cable stripping system containing a multi-core wire cutting device also includes a wire pay-out device, a single-core stripping device, a first wire stabilizing device, a second wire stabilizing device, a branch wire stripping device and a wire take-up device, wherein the wire pay-out device, the single-core stripping device, the first wire stabilizing device, the multi-core wire cutting device, the second wire stabilizing device, the branch wire stripping device and the wire take-up device are arranged in sequence.

[0012] The wire-paying device is used for storing and paying out wires; the single-core stripping device is used for stripping the outer sheath of the cable; the first wire-stabilizing device and the second wire-stabilizing device are crawler-type traction machines, which pull the cable to ensure a stable cable traction speed and traction tension; after the multi-core wire cutting device cuts the insulation layer of each wire core, the wire stripping device is used to strip the insulation layer of the insulated wire core; the wire-reeling device is used to recover the conductor with the insulation layer stripped off.

[0013] The multi-core wire cutting device of the present invention can cut the insulation layer of each wire core at one time, and the multi-core cable stripping system can separate the sheath layer of the multi-core twisted cable and the insulation layer of each wire core at one time, stably strip the plastic (insulation layer) and conductor of the waste cable, and realize the rapid separation and recovery of the cable insulation skin and the conductor.
