Description

Technical Field

[0001] The present invention belongs to the technical field of cable joint production equipment, and particularly relates to a production equipment for three-core cross-linked cable cold shrink joints and an intermediate joint. Background Art

[0002] The cold shrink joint production equipment refers to the equipment required in the production process of cable cold shrink joints. After the cable production is completed, the end of the cable needs to be peeled, and then the end of the cable is processed. The production of cold shrink cable terminal heads is to inject and vulcanize an elastomer material in a factory, and then expand the diameter and line with a plastic spiral support to form various components of cable accessories. During installation, these pre-expanded sleeves are put on the end or joint of the processed cable, and the internal supporting plastic spiral strip is drawn out and pressed on the cable insulation to form a cable accessory. Because it relies on elastic retraction force at room temperature, rather than using fire heating to shrink like heat shrink cable accessories, it is commonly known as cold shrink cable accessories.

[0003] The existing cold shrink joint production equipment mainly includes a machine frame, a driving roller, a driving roller, a pressing roller, a material roller for winding the cable, and a cutting tool for peeling the cable. When in use, due to the action of the driving roller, the cable on the material roller can pass through the driving roller and the pressing roller and then be transported to the cutting tool, where the cable can be peeled.

[0004] However, in the actual use process, during the cable peeling process, the cable needs to be rotated so that the cutting tool can surround the cable for peeling. During the rotation process, the three-core cross-linked cable cores are prone to entanglement. Moreover, after peeling, the three cores are exposed and are also prone to entanglement. The extrusion force between the cores can easily cause the outer surface of the cores to be continuously bent, resulting in fracture or damage. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] For the production equipment of the three-core cross-linked cable cold shrink joint and the intermediate joint, by setting the skin scraping and wire dividing device, under the action of the first threaded rod and the first threaded hole block, the first rectangular frame can move to the cable joint. At this time, under the action of the second threaded rod, the two second threaded hole blocks move towards each other, and then can drive the semi-circular arc plate and the semi-circular blade to fit with the outer skin of the cable joint. Then, when moving outwards, the outer skin can be peeled off. Since the two semi-circular blades just fit the shape of the outer skin of the cable joint, the outer skin can be peeled off at one time. And under the action of the pointed rod and the bifurcated plate, after the cable joint is skinned, the pointed rod can be inserted into the center of the three cores, and under the action of the bifurcated plate, the three cores can be separated by a certain distance to avoid entanglement.

[0020] The production equipment and intermediate joint of this three-core cross-linked cable cold shrink joint can disassemble and assemble the material roller under the action of the auxiliary transmission device, the round clamping block and the round clamping frame, thus facilitating loading and unloading. When the cable joint needs to be peeled, the material roller needs to be fixed and not rotate at this time, so as to avoid the movement of the cable joint caused by the rotation of the material roller during the peeling process. At this time, under the action of the third threaded rod and the first threaded hole plate, the threaded clamping rod and the second threaded hole plate are driven to move. Since the rotation causes the change of the thread angle at the opening of the threaded cartridge, the threaded clamping rod needs to rotate a certain distance in the second threaded hole plate in advance to match it, so as to fix the material frame. Under the action of the arc clamping block and the annular card slot, the cable body can be limited and the driving roller can be fixed.

[0021] The production equipment and intermediate joint of this three-core cross-linked cable cold shrink joint can change the position of the support ring by setting the wire splitting and supporting device, and the sliding block slides on the inner wall of the rectangular groove, thus supporting the cable body and having a certain separating effect to avoid entanglement. Under the action of the wire splitting plate, the three cores can be separated to avoid entanglement. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The working principle of the present invention is as follows:

[0040] S1. When skin removal is required, at this time, the round clamping block 86 on the material roller 85 is clamped into the round clamping frame 81. At this time, the blocking block 84 will drive the second spring 83 to deform. Then, the round clamping block 86 at the other end is clamped into another round clamping frame 81. Under the action of the third spring 811, the round clamping cylinder 810 is fixed to the round clamping hole 82. At this time, the driving roller 4 can drive the cable body 14 to move, thereby driving the transmission roller 2 to rotate, and then driving the extrusion roller 13 to rotate. When it moves to an appropriate position, at this time, the third threaded rod 891 is rotated, so that the third threaded rod 891 can drive the first threaded hole plate 894 to move, and then drive the second threaded hole plate 896 to move to an appropriate position. At this time, the threaded clamping rod 897 is rotated, so that the threaded clamping rod 897 is fixed to the threaded clamping cylinder 892;

[0041] S2. At this time, the second motor 73 is started, so that the second motor 73 drives the first threaded rod 74 to rotate, and then can drive the first threaded hole block 75 to move, and then drive the first rectangular frame 710 to move, and then move to an appropriate position. At this time, the second threaded rod 711 is rotated, so that the second threaded rod 711 can drive the second threaded hole block 713 to move, and then drive the semi-circular arc plate 715 and the semi-circular blade 716 to move, and then fix the cable body 14. At this time, under the action of the first threaded rod 74, the outer skin of the cable joint can be peeled off outward;

[0042] S3. When it is necessary to prevent the cable body 14 from being entangled, the slider 92 is pushed at this time, so that the slider 92 can drive the auxiliary block 93 to move, and then the clamping rod 94 can be driven to be clamped into the clamping hole. At this time, the support ring block 96 can support the cable body 14, and the wire dividing board 99 can divide the cable body 14 to avoid entanglement.
