DETAILED DESCRIPTION

[0019] The following will be described in detail with reference to the accompanying drawings. Figs. 1-3 The application is further described in detail.

[0020] The embodiments of the application disclose a wire and cable stranding device. Figs. 1-3 A wire and cable stranding device, comprising a device base 1, a driving motor 2 is installed inside the device base 1, a fixed inner cavity 3 is formed in the top of the device base 1, a driving gear 4 is installed on the upper surface output end of the driving motor 2 and extends into the fixed inner cavity 3, a plurality of driven gears 5 are rotatably installed on the inner wall of the fixed inner cavity 3 at the upper and lower ends of the two sides, the driving gear 4 is located inside the plurality of driven gears 5, the driven gears 5 are movably close to the outer surface of the driving gear 4, the driving gear 4 and the driven gears 5 are mutually engaged, a spline shaft 6 is installed on the top end of the middle of the driven gear 5 and extends to the upper surface of the device base 1, a wire reel 7 is sleeved on the outer surface of the spline shaft 6, a spline hole is formed through the top end of the middle of the wire reel 7, the spline shaft 6 is located on one side of the spline hole on the outer surface, the spline shaft 6 and the spline hole are mutually embedded, and a guide mechanism is further arranged on the upper surface of the device base 1, a plurality of fixed rods 8 are fixedly installed on the outer surface of the device base 1, and a connecting ring plate 9 is fixedly connected between the plurality of fixed rods 8 and close to the upper part of the device base 1.

[0021] By winding different types of cable lines 14 on each wire reel 7 respectively, the driving motor 2 is turned on, and the output shaft of the driving motor 2 drives the driving gear 4 to rotate. Since the driving gear 4 and the plurality of driven gears 5 at the upper and lower ends of the two sides of the inner wall of the fixed inner cavity 3 are mutually engaged, the rotation of the driving gear 4 will drive the driven gears 5 to rotate synchronously. When the driven gears 5 rotate, the spline shaft 6 at the top end of the middle of the driven gears 5 will also rotate, and since the spline shaft 6 and the wire reel 7 are mutually embedded through the spline hole, the rotation of the spline shaft 6 can drive the wire reel 7 to rotate, so that the plurality of wire reels 7 will rotate simultaneously, realizing the simultaneous stranding operation of the plurality of wires.

[0022] Reference Fig. 1 and Fig. 2The guiding mechanism comprises a plurality of guiding struts 10 fixedly installed at the middle of the top end of the device base 1, guiding plates 11 movably installed on the outer surfaces of the guiding struts 10, a plurality of limiting holes 12 penetratingly formed on the outer surfaces of the guiding plates 11 at positions corresponding to the wire reels 7, a connecting handle 13 fixedly installed on the top end of the middle of the guiding plate 11, and a plurality of cable wires 14 wound around the outer surfaces of the wire reels 7, the outer diameters of the cable wires 14 being smaller than the inner diameters of the limiting holes 12, and the outer surfaces of the cable wires 14 penetrating through the limiting holes 12 and located inside the connecting ring plate 9.

[0023] By penetrating one end of the cable wire 14 through the corresponding limiting hole 12 on the guiding plate 11, the one end of the cable wire 14 is located inside the connecting ring plate 9, the connecting handle 13 is held, and the guiding plate 11 is moved on the guiding strut 10. The limiting hole 12 on the guiding plate 11 changes position with the movement of the guiding plate 11, thereby guiding and limiting the movement track of the cable wire 14.

[0024] The implementation principle of the wire and cable stranding device is as follows: when the wire and cable need to be stranded, different types of cable wires 14 are wound around the wire reels 7, and one end of the cable wire 14 is penetrated through the corresponding limiting hole 12 on the guiding plate 11, so that the one end of the cable wire 14 is located inside the connecting ring plate 9.

[0025] Then, the driving motor 2 is started, the input end of the power supply of the driving motor 2 is electrically connected with the output end of the external power supply, and the output shaft of the driving motor 2 drives the driving gear 4 to rotate. Since the driving gear 4 is meshed with the plurality of driven gears 5 on the upper and lower ends of the inner wall of the fixed inner cavity 3, the rotation of the driving gear 4 drives the driven gears 5 to rotate synchronously. When the driven gears 5 rotate, the spline shaft 6 at the top end of the middle of the driven gears 5 also rotates, and since the spline shaft 6 is embedded with the wire reel 7 through the spline hole, the rotation of the spline shaft 6 drives the wire reel 7 to rotate. In this way, the plurality of wire reels 7 rotate simultaneously, realizing the simultaneous stranding operation of the plurality of wires and greatly improving the stranding efficiency.

[0026] During the stranding process, the operator can move the guiding plate 11 on the guiding strut 10 by holding the connecting handle 13 according to the type of the wire and the stranding requirement. The limiting hole 12 on the guiding plate 11 changes position with the movement of the guiding plate 11, thereby guiding and limiting the movement track of the cable wire 14. Different types of wires are guided through different limiting holes 12, realizing the classified stranding of different wires and meeting the diversified production requirements. When the stranding operation is completed, the driving motor 2 is turned off, and the stranded wire and cable can be taken out, completing the entire stranding process.
