Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.
The applicant researches and discovers that when the existing wire stripping device is used for stripping a multi-core wire cable, an operator is generally required to pull out a plurality of core wires of the cable and flatly lay the core wires on the wire stripping device, and then the wire stripping device is started to cut and pull out the sheath of the cable. If the operation of the operator is improper, the safety of the operator is easily threatened. In addition, if the core wires are not even, the skin cutting tool cannot cut the skin of all the core wires, so that part of the core wires cannot finish the skin pulling process, and rework is needed.
In order to solve the problems existing in the prior art, the utility model provides a separated time mechanism 10 for multicore wire stripping device 1. As shown in fig. 1, the branching mechanism 10 includes a branching horizontal plate 11, a branching speed reducer 12, a branching motor 13, and a branching rotation shaft 14.

The branching speed reducer 12 is fixed on the rear end face of the cutting vertical plate 31, and the branching motor 13 is connected with the branching speed reducer 12; and the output end of the branching motor 13 is connected with the input end of the branching speed reducer 12. The wire distributing rotating shaft 14 stretches across the upper side of the wire distributing transverse plate 11 along the length direction of the wire distributing transverse plate 11, and two ends of the wire distributing rotating shaft 14 are rotatably connected with the wire distributing transverse plate 11 through a bearing base 15. One end of the branching rotating shaft 14 horizontally penetrates through the cutting vertical plate 31 and is connected with the output end of the branching speed reducer 12. A spiral branching blade 16 is provided on the circumferential surface of the branching shaft 14 in the longitudinal direction. When the branching motor 13 drives the branching rotating shaft 14 to rotate after being decelerated by the branching speed reducer 12, the branching blades 16 rotate spirally and shift a plurality of core wires of the cable to one side, the core wires can sequentially fall into the branching guide groove 111 in the moving process, and the branching blades 16 continue to shift the core wires which do not enter the branching guide groove 111 so that all the core wires enter the branching guide groove 111. Since the wire dividing guide groove 111 and the top surface of the wire dividing horizontal plate 11 have a height difference in the height direction, the core wire that first enters the wire dividing guide groove 111 is not pulled out by the wire dividing blade 16. Because the branching guide grooves 111 are uniformly arranged, a plurality of core wires of the cable can be uniformly separated, manual operation of operators is not needed in the process, and safety is improved. Meanwhile, the core wires are evenly separated, so that the skin can be cut conveniently.

The front end face to the rear end face of the cutting vertical plate 31 are provided with vertical guide grooves 311 in the vertical direction, and the connecting cross rod 351 horizontally penetrates through the vertical guide grooves 311. The top of the upper knife plate 34 is fixedly connected to the bottom of the connecting cross piece 352. When the vertical cylinder 35 runs, the telescopic rod of the vertical cylinder stretches and drives the connecting cross block 352 to move up and down through the connecting cross rod 351 so as to adjust the distance between the upper knife board 34 and the lower knife board 33, and then the outer skin of the core wire is cut.
In a further embodiment, the vertical movement assembly 35 further includes a vertical guide 353 vertically fixed to a front face of the cut riser 31 to guide the connecting cross piece 352 to slide up and down. Meanwhile, the rear end face of the connecting cross block 352 is provided with a vertical sliding groove (not shown) matched with the vertical guide rail 353. The vertical guide 353 guides the horizontal connecting block 352 in the vertical direction, thereby improving the stability of the horizontal connecting block 352 and the upper blade 34 during movement. The vertical guide 353 guides the connecting cross block 352 in the vertical direction, so that the connecting cross block 352 is prevented from shaking to both sides, and the stability of the connecting cross block 352 and the upper cutter plate 34 in the moving process is improved.

When the upper blade 34 moves downward, the distance between the upper blade 341 and the lower blade 331 is reduced to peel the core wires dispersed in the branching guide groove 111, and since the branching guide groove 111 transversely corresponds to the lower blade 331, it is ensured that all the core wires dispersed in the branching guide groove 111 can be peeled, thereby reducing rework.
In the process that the wire distributing blade 16 shifts the core wires, the wire distributing blade 16 applies shifting force to the core wires, so that the cables are easy to roll. To address this problem, in a further embodiment, an upper pressure plate 36 is secured to the bottom of the end of the connecting cross piece 352 remote from the upper knife plate 34. As the connecting cross piece 352 moves up and down, the distance between the upper press plate 36 and the branching cross plate 11 increases or decreases. When the connecting cross block 352 moves downward, the distance between the upper press plate 36 and the cable divider cross plate 11 decreases and compresses the cable. Thereby preventing the cable from rolling during the shifting of the core wire of the cable by the splitter blade 16. The upper pressing plate 36 is made of an elastic member, so that when the upper pressing plate 36 presses the cable, the connecting cross block 352 still has a space for moving downwards, and the upper knife plate 34 can continuously move downwards to cooperate with the lower knife plate 33 to cut the outer skin at the end of the core wire.
