Description

Technical Field

[0001] The invention belongs to the technical field of cable processing, and in particular relates to a cable processing device. Background Art

[0002] There are various cable processing equipments. In some cable production and processing, wrapping equipment is sometimes used. Wrapping equipment is mainly used to wrap various materials, such as insulating paper, mica tape, non-woven fabric, etc., around the cable core or insulation layer of the cable. Wrapping can enhance the insulation performance, mechanical strength, fire resistance and other functions of the cable. For example, a cable wrapping device disclosed in the invention patent with the authorized patent announcement number of CN110600204B includes a frame, a wrapping disk rotatably connected to the frame, and a driving motor for driving the wrapping disk to rotate; a through hole for the cable to pass through is provided at the center position of the wrapping disk; an adjusting seat is fixedly connected at the eccentric position of the wrapping disk, a wrapping rod is hinged on the adjusting seat through a hinge shaft, a wrapping drum is rotatably connected to the wrapping rod along the axis, and a wrapping tape is wound on the wrapping drum; an adjusting device for adjusting the rotation angle of the wrapping rod is provided on the adjusting seat, and this type of wrapping machine can only realize single-layer wrapping.

[0003] There are also wrapping machines that have multiple wrapping rods on the wrapping disk, but this type of wrapping machine can only wrap in the same direction, which is prone to wrapping defects. For example, there is a gap between the wrapping tapes wound in the same direction. Although the gap can be reduced during wrapping by adjusting the wrapping angle, the width of the wrapping tape overlaps a lot, which wastes the wrapping tape. There are also some devices that wrap the cable in the opposite direction to improve the quality of the wrapping layer, but two machines need to be arranged. However, during the operation of the equipment, the synchronization effect is likely to be poor due to the winding speed problem. At the same time, the wrapping tape pulls the cable in the opposite direction during the wrapping process, which is likely to cause the cable to swing. At the same time, in the production process of multi-layer wrapped cables, due to problems with the winding quality of the wrapping tape, it is very inconvenient to rework and wrap the middle part of the cable. Therefore, a cable processing equipment that can solve the defects of the prior art is needed. Summary of the invention

[0006] Furthermore, circular holes are provided on the support frame 1 and the support frame 2, and the circular holes are provided coaxially with each other. The wrapping ring 1 and the wrapping ring 2 are respectively arranged in the circular holes provided on the support frame 1 and the support frame 2, and the wrapping ring 1 and the wrapping ring 2 are rotatably connected to the inner wall of the circular hole.

[0007] Furthermore, a plurality of bearings are installed around the circular holes on the support frame 1 and the support frame 2, and grooves are provided on the outer sides of the wrapping ring 1 and the wrapping ring 2, and the outer rings of the bearings are located in the grooves.

[0008] Furthermore, the support frame 1 and the support frame 2 are both provided with a notch 1, the wrapping ring 1 and the wrapping ring 2 are both provided with a notch 2, the support frame 1 is provided with at least one positive synchronization wheel meshing with the wrapping ring 1, the positive synchronization wheel is transmission-connected with the positive driving wheel, the support frame 2 is provided with at least two anti-synchronous wheels meshing with the wrapping ring 2, and the anti-synchronous wheels are transmission-connected with each other.

[0009] Furthermore, the wire device includes a connecting plate arranged between the support frame 1 and the support frame 2, the connecting plate 1 is hinged with a support rod 1, and an elastic member is connected to the hinge between the support rod 1 and the connecting plate 1, and the base is fixedly mounted with a support rod 2, and the support rod 1 and the support rod 2 are respectively rotatably connected with a guide wheel 1 and a guide wheel 2, and the outer sides of the guide wheel 1 and the guide wheel 2 are both provided with arc grooves, and the guide wheel 1 abuts against the guide wheel 2 to make the arc grooves form a wire through hole.

At the same time, the directions of the double-layer wrapping are opposite. Compared with the double-layer wrapping in the same direction, the displacement of the wrapping tape during the bending process can be avoided to cause gaps, and the sealing effect is better. At the same time, when used for wrapping the electromagnetic shielding layer of the cable, the two layers of electromagnetic shielding wrapping tapes wound in the positive and negative directions have opposite induction directions of the magnetic field. When the external magnetic field passes through the two layers of wrapping tapes, the induced magnetic fields generated by the two layers of wrapping tapes will offset each other, thereby reducing the magnetic field strength that finally penetrates into the cable, improving the electromagnetic shielding effect, and reducing the interference of the external electromagnetic field on the internal signal of the cable compared to the two layers of wrapping tapes wound in the same direction; Furthermore, the present invention facilitates rework of defects produced in the middle of a long-distance cable by providing a conductor device in conjunction with the gaps one and two, and facilitates loading and unloading of the middle portion of the cable.
