Description

Technical Field

[0001] The present application relates to the technical field of cable manufacturing, and particularly relates to a manufacturing device and a manufacturing method for multi-core cable branching and parallel connection. Background Art

[0002] A cable is made of one or more mutually insulated core conductors and an outer insulating protective layer, and is a wire for transmitting electric power or information from one place to another. The insulating layer, as an important part of the cable, plays a role in anti-corrosion and moisture-proof in addition to the isolation function during use. In a wiring site, multiple cables are used for power transmission. In the wiring site, multiple groups of cables of the same type need to be more bundled, so that the on-site use area is more space-saving and more beautiful and tidy. Therefore, generally, multiple cables are adhered to each other in a row, which is called a parallel-connected cable for convenient use.

[0003] In the related art, the manufacturing device for a cable includes a wire feeding mechanism, a heating mechanism, an extrusion mechanism, a traction mechanism, a spark tester, and a wire winding mechanism arranged in sequence. The wire feeding mechanism feeds multiple cables and arranges the multiple cables in a row. The multiple cables arranged in a row are called a row of cables. The heating mechanism heats the row of cables, so that the insulating protective layer on the surface of the row of cables is softened. The extrusion mechanism includes two extrusion wheels. The heated row of cables passes between the two extrusion wheels, and the extrusion wheels extrude the width direction of the cables arranged in a row, so that adjacent cables are adhered to each other to form a parallel-connected cable. The traction mechanism provides a pulling force for the row of cables, and the spark tester detects the row of cables. If the insulating protective layer is broken through by the spark tester, the quality of the row of cables does not meet the requirements. The wire winding mechanism winds up the row of cables after processing to facilitate the transportation of the row of cables.

[0004] However, when the number of cables arranged in a row is large, the two extrusion wheels extrude the width direction of the cables arranged in a row, which easily causes the adjacent single cables to be misaligned, affecting the flatness of the parallel-connected cable and thus affecting the final processing quality.

[0053] There are multiple groups of cables of the same type required at the wiring site, and they need to be more bundled, so that the on-site use area can save more space and be more beautiful and tidy. Therefore, multiple cables need to be arranged in a row and bonded to each other. The multiple cables arranged in a row are called row cables, and the bonded parts of the row cables are called parallel cables. Due to different on-site use environments, the bundled cables need to separate multiple cables from each other at both ends of the parallel cables for convenient wiring. The separated parts of the row cables are called branched cables. Therefore, during the continuous processing of row cables, it is necessary to alternately perform parallel and branch operations on the row cables, so that the row cables alternately form parallel cables and branched cables.

[0054] The following is a further detailed description of this application in conjunction with the attached Figures 1-4 drawings.

[0055] Embodiment 1:

[0056] Embodiment 1 of this application provides a manufacturing device for multi-core cable branching and parallel connection.

The heated area of the row of cables is processed into a parallel cable in the subsequent process. When the rotary drive source 23 drives the rotating roller 22 to rotate, the hot air groove 221 can be made not to face the row of cables, and at this time, the row of cables is not heated. The unheated area of the row of cables serves as a branched cable.
