[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1-5 As shown, a stranding device for wire and cable production includes a base 1 and a motor 2. A rotating shaft 21 is fixedly connected to the middle of the front side of the motor 2, a winding mechanism 3 is fixedly connected to the middle of the outer surface of the rotating shaft 21, a rotating mechanism 4 is fixedly connected to the front middle of the outer surface of the rotating shaft 21, an adjusting mechanism 5 is fixedly connected to the front side of the outer surface of the rotating shaft 21, and five adjusting mechanisms 6 are arranged in a ring array on the front side of the adjusting mechanism 5.

[0025] During actual operation, the above device needs to cooperate with the cable and wire take-up device and the traction device to carry out the overall stranding reeling.

[0026] During the specific implementation of the above-mentioned device, the winding mechanism 3 and the adjustment mechanism 1 5 cooperate with the adjustment mechanism 2 6 to twist the five strands of wires that need to be twisted together in cooperation with an external traction device, and then pull the wires into the winding device for winding. At the same time, the angle of the wire input during the twisting process can be adjusted by the rotating mechanism 4, thereby adjusting the tension of the wire twisting to ensure the quality of the twisted wire.

[0027] See Figure 2The winding mechanism 3 comprises a rotating roller 31 fixedly connected to the middle part of the outer surface of the rotating shaft 21, and five wire barrels 32 are annularly connected to the outer surface of the rotating roller 31.

[0028] Specifically, when the several wires need to be stranded, the rotating shaft 21 is driven to rotate by the motor 2, and the rotating roller 31 is driven to rotate at the same time, and the five wire barrels 32 are driven to rotate at the same time in the rotating process of the rotating roller 31, and the wires to be stranded are drawn out from the surface of the wire barrel 32, and the adjusting mechanism one 5 adjusts the wires drawn out from the wire barrel 32 to guide and adjust the tension so as to perform the next step of stranding.

[0029] Referring to Figure 5 The adjusting mechanism two 6 comprises four spring threes 62 fixedly connected to the inner surface of the through hole 541, and the limiting plates 61 are fixedly connected to the ends of the spring threes 62 away from the inner surface of the through hole 541.

[0030] Specifically, the four limiting plates 61 cooperatively form a cylindrical shape, and the two ends of the limiting plate 61 are arc-shaped, and the four limiting plates 61 cooperatively guide the wires drawn out from the wire barrel 32, and can cooperatively adapt to the wires of different thicknesses for stranding, and the arc-shaped limiting plate 61 at the two ends can avoid friction between the wires and the limiting plate 61 in the input and output process, thereby avoiding abrasion of the wires, and causing quality problems of the cable wires.

[0031] Referring to Figure 4 and Figure 5 The adjusting mechanism one 5 comprises a circular ring 51 fixedly connected to the outer surface of the front part of the rotating shaft 21, five guide rings 52 annularly fixedly connected to the rear end of the circular ring 51, five sector blocks 54 annularly arranged on the outer surface of the circular ring 51, limiting rods 53 fixedly connected to the rear side lower part of the sector block 54 on the inner surface of the guide ring 52, and spring twos 55 fixedly connected to the middle part of the side of the sector block 54 close to the outer surface of the circular ring 51.

[0032] Further, when the wires are stranded through the inner surface formed by the four limiting plates 61, the rotating shaft 21 is driven to rotate, thereby driving the circular ring 51 to rotate, and the five sector blocks 54 are driven to rotate at the same time, and further the sector block 54 can drive the four spring threes 62 and the limiting plate 61 to rotate at the same time, thereby driving the wires to rotate, and cooperating with the external stranding device to strand the wires.

[0033] Referring to Figure 5 The sector block 54 is provided with a through hole 541 at the front end, and the sector block 54 is provided with an arc-shaped groove 542 at the middle part of the side close to the circular ring 51, and the inner surface top of the arc-shaped groove 542 is fixedly connected to the upper end of the spring two 55.

[0034] Further, when the circular ring 51 rotates, the spring 55 cooperates with the arc-shaped groove 542 to drive the sector block 54 to rotate, and the guide ring 52 and the limiting rod 53 are driven to rotate by the circular ring 51.

[0036] Specifically, when the rotating shaft 21 rotates counterclockwise, the arc-shaped tooth ring 42 is driven to rotate, and the two arc-shaped stoppers 43 are inserted between the arc-shaped teeth of the arc-shaped tooth ring 42 to block the rotation of the arc-shaped tooth ring 42, so that the arc-shaped tooth ring 42 drives the two arc-shaped stoppers 43 to rotate, and the gear one 41 is driven to rotate by engaging the gear two 44 in the rotating process;

[0037] Further, when the gear two 44 rotates, the V-shaped elastic sheet 45 is pressed downward to compress the spring one 451, and when the gear two 44 rotates to the upper part of the V-shaped elastic sheet 45 between the two teeth, the spring one 451 pushes the upper part of the V-shaped elastic sheet 45 upward, and the spring one 451 is continuously compressed and then restored to its original state during the rotation of the gear two 44 driven by the gear one 41, so as to drive the upper part of the V-shaped elastic sheet 45 to move downward and then upward.

[0038] Referring to Figure 3 The front end of the gear one 41 is annularly and arrayedly provided with five arc-shaped holes 411, the two arc-shaped tooth rings 42 are in close contact with the outer surfaces of the arc-shaped stoppers 43, the inner surface of the V-shaped elastic sheet 45 is fixedly connected with the spring one 451, the upper end of the V-shaped elastic sheet 45 is in close contact with the outer surface of the gear two 44, and the outer surface of the handle 46 is rotatably connected to the upper end of the base 1.

[0039] When it is necessary to adjust the input angle of the electric wire to adjust the tension of the electric wire twisting, the upper part of the V-shaped elastic sheet 45 is pushed downward to compress the spring one 451, and the handle 46 is reversely rotated to reversely rotate the gear two 44, at this time, the gear two 44 drives the gear one 41 to rotate clockwise by engaging, at this time, the gear one 41 drives the two arc-shaped stoppers 43 to rotate clockwise, at this time, the arc-shaped surfaces of the two arc-shaped stoppers 43 slide on the arc-shaped tooth surfaces of the arc-shaped tooth ring 42, and the arc-shaped tooth ring 42 is not driven to rotate;

[0040] Further, when the gear one 41 rotates clockwise, the five limiting rods 53 slide upward along the inner surface of the arc-shaped hole 411, and the guiding ring 52 limits the movement of the limiting rods 53, so that the limiting rods 53 only move upward along a straight line during the sliding process, and the limiting rods 53 drive the sector blocks 54 to move outward, and the second springs 55 are stretched at this time;

[0041] Further, when the sector blocks 54 are driven by the limiting rods 53 to move outward, the four limiting plates 61 drive the wires close to the inner surface of the limiting plates 61 to move outward, so as to expand the input angle of the wires during the wire twisting process, and further expand the tension of the twisted wires;

[0042] When the position is adjusted to a suitable position, the V-shaped elastic sheet 45 is released, and the upper part of the V-shaped elastic sheet 45 is inserted between the two teeth of the gear two 44 by the first spring 451, so as to avoid the rotation of the gear two 44 and change the rotation of the gear one 41;

[0043] Further, the rotation shaft 21 drives the arc-shaped tooth ring 42 to rotate counterclockwise, so that the two arc-shaped blocks 43 cooperate with the arc-shaped tooth ring 42 to drive the gear one 41 to rotate, and the wires are twisted with different tensions.
