DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 The wire twisting machine for power cable processing comprises a support plate 1, a motor mounting plate 2 is fixedly mounted on the end of the support plate 1, a motor 3 is fixedly mounted on the top of the motor mounting plate 2, a first fixing plate 4 is mounted on the top of the support plate 1, a fixing rod 9 is fixedly connected to the top of the first fixing plate 4, a wire twisting mechanism for cable twisting is arranged on the top of the fixing rod 9, a second fixing plate 16 is fixedly connected to the top of the support plate 1, a wire outlet hole 17 is opened inside the second fixing plate 16, a water pumping tank 18 and a water storage tank 20 are fixedly connected to the top of the support plate 1, a connecting pipe 19 is connected between the water pumping tank 18 and the water storage tank 20, a spiral heat dissipation pipe 21 is connected to the upper end of the water storage tank 20, an end of the spiral heat dissipation pipe 21 away from the water storage tank 20 is connected to a water inlet pipe 22, an end of the water inlet pipe 22 away from the spiral heat dissipation pipe 21 is communicated with the water pumping tank 18, a driving mechanism is installed inside the water pumping tank 18, and the driving mechanism is used to drive the coolant in the water storage tank 20 to flow.

[0023] The wire twisting mechanism includes a rotating rod 5, a first transmission wheel 6 and a transmission belt 7. The output end of the motor 3 is fixedly connected to the rotating rod 5, the rotating rod 5 is rotatably connected to the first fixed plate 4, the end of the rotating rod 5 away from the first fixed plate 4 is fixedly connected to the first transmission wheel 6, the end of the fixed rod 9 away from 4 is rotatably connected to the second transmission wheel 8, the first transmission wheel 6 and the second transmission wheel 8 are transmission-connected through the transmission belt 7, and a winding drum 10 is fixedly connected to the side wall of the second transmission wheel 8, and a winding hole 101 is opened on the surface of the winding drum 10. The winding hole 10 is set to be concave, which is more convenient for the wire to pass through.

[0024] A plurality of wire-releasing holes 801 are provided on the surface of the second transmission wheel 8, a first wire wheel 802 is fixedly installed on the top of the wire-releasing hole 801, a groove 803 is provided at the bottom of the wire-releasing hole 801, a spring 804 is fixedly installed inside the groove 803, a wire wheel fixing plate 805 is installed at the end of the spring 804 away from the groove 803, and a second wire wheel 806 is fixedly connected to the wire wheel fixing plate 805. This design allows adjustment of wires of different thicknesses and fixation of the wires during the twisting process to prevent the wires from falling off during rotation.

[0025] The driving mechanism includes a reciprocating screw 11, a reciprocating nut 12, a piston rod 13 and a piston 15. The piston 15 is sealingly and slidably connected in the water pumping box 18. The end of the piston 15 is connected to the piston rod 13. The end of the piston rod 13 away from the piston 15 is fixedly connected to the reciprocating nut 12. The reciprocating nut 12 is threadedly connected to the reciprocating screw 11. The reciprocating screw 11 is fixedly connected to the first transmission wheel 6. The upper end of the support plate 1 is fixedly connected to the limit plate 14. The reciprocating screw 11 is rotatably connected to the side wall of the limit plate 14. The piston rod 13 slides through the limit plate 14, so that the reciprocating nut 12 is guided to slide horizontally on the reciprocating screw 11 to prevent the reciprocating nut 12 from detaching from the reciprocating screw 11.

[0026] The upper end of the water pumping box 18 is connected with a water inlet pipe 22, which is connected to the spiral heat dissipation tube 21. Both the water inlet pipe 22 and the connecting pipe 19 are equipped with a one-way valve. The piston 15 slides back and forth inside the water pumping box 18, so that the one-way valve of the water inlet pipe 22 draws the coolant into the water pumping box 18, and then pushes the coolant into the water storage tank 20 from the one-way valve of the connecting pipe 19. This repeated cycle allows the coolant in the spiral heat dissipation tube 21 to continue to maintain a low temperature.

[0027] In the present invention, one end of the wire is passed through the wire-releasing hole 801, and the second wire wheel 806 inside is squeezed by force to drive the wire wheel fixing plate 805 to squeeze its spring 804, so that the second wire wheel 806 slides down, which is convenient for adjusting wires of different thicknesses to pass through. After passing through, the spring 804 rebounds to fix the wire between the two wire wheels to avoid it from coming off during the wire twisting process.

[0028] The starting motor 3 drives the rotating rod 5 to rotate, and drives the first transmission wheel 6 outside it to rotate, and then drives the reciprocating screw 11 to rotate, so that the reciprocating nut 12 mounted on the outside thereof slides reciprocatingly with it, and at the same time drives the piston rod 13 and the piston 15 to slide in the water pumping box 18. When the piston 15 slides inward, the coolant in the water pumping box 18 is discharged into the spiral heat dissipation tube 21 through the water inlet pipe 22. When the piston 15 slides outward, the water pumping box 18 draws out the coolant in the water storage tank 20 through the connecting pipe 19. This is repeated to circulate the coolant inside the spiral heat dissipation tube 21, so as to keep the temperature of the spiral heat dissipation tube 21 at a low temperature.

[0029] In addition, when the first transmission wheel 6 rotates, the second transmission wheel 8 will be driven to rotate through the transmission belt 7, and the wire fixed on the surface will also rotate accordingly. The wires are twisted together through the twisting drum 10 and pass through the outlet hole 17 and continue to pass through the middle of the spiral heat dissipation tube 21. The coolant flows in the spiral heat dissipation tube 21 to absorb and dissipate the heat on the surface of the cable, so that the cable will not be unusable or its service life will be reduced due to excessive temperature during the twisting process.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
