Description

Technical Field

[0001] The utility model relates to the technical field of conductive wire processing, in particular to a wire head pulling device for conductive wire processing. Background Art

[0002] During the coating process of the conductive wire, the conductive wire needs to be pulled to ensure that the conductive wire is in a taut state during the processing. In the existing technology, the pulling is generally performed by manually pulling the wire head, which not only increases the labor workload of the workers, but also is not conducive to winding.

[0003] According to a Chinese patent document with publication number CN212712113U, a filament head pulling device for processing white conductive filaments is disclosed. By starting a rotary motor, the winding roller rotates, thereby pulling the white conductive filament to the right, saving manual labor. In combination with the use of a clamping device, the white conductive filament is kept taut during processing, facilitating processing. However, the above device is unable to measure the length of the wound conductive filament during use, and cannot ensure that the length of the wound conductive filament after each coating is within a small range, which is not conducive to the subsequent packaging and sales of the conductive filament. To this end, a filament head pulling device for processing conductive filaments is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a wire head traction device for conductive wire processing includes a base 1, and a counting wheel 4, a tensioning wheel 3 and a traction take-up drum 2 are sequentially arranged above the base 1. The outer surface of the counting wheel 4 is provided with a receiving groove 13 of an annular structure acting on the conductive wire, and the two ends of the counting wheel 4 are rotatably connected to the first vertical plate 6 respectively, and the first vertical plate 6 is fixedly connected to the base 1. A tachometer 7 acting on the counting wheel 4 is provided on the side wall of the first vertical plate 6, and the two ends of the tensioning wheel 3 are respectively provided with a second vertical plate 14, and the second vertical plate 14 is fixedly connected to the base 1. A tensioning mechanism is provided between the second vertical plate 14 and the tensioning wheel 3, and the two ends of the traction take-up drum 2 are rotatably connected to the third vertical plate 18 respectively, and the third vertical plate 18 is fixedly connected to the base 1, and an anti-backward driving mechanism acting on the traction take-up drum 2 is provided on the third vertical plate 18.

[0021] Among them, the tensioning mechanism consists of a slider 15 and a spring 17. The two ends of the tensioning wheel 3 are rotatably connected with the slider 15. The two sliders 15 are slidably installed in the slide grooves 16 opened on the two second vertical plates 14. The spring 17 is fixedly connected between the inner top wall of the slide groove 16 and the slider 15.

[0022] When the traction take-up drum 2 is pulling and winding the conductive wire, the conductive wire will generate an upward pulling force on the tensioning wheel 3, thereby slightly compressing the spring 17. The force of the spring 17 to restore the deformation will keep the conductive wire in a straight state.

[0023] Among them, the anti-backward driving mechanism consists of a turbine 19, a worm rod 20, a fixed plate 21 and a motor 5. The turbine 19 is rotatably connected to the side wall of the third vertical plate 18. The turbine 19 is fixedly connected to the traction take-up drum 2. A worm rod 20 engaged with it is provided below the turbine 19. The two ends of the worm rod 20 are rotatably connected to the fixed plates 21 respectively. The fixed plate 21 is fixedly connected to the third vertical plate 18. The motor 5 is fixedly connected to the side wall of the fixed plate 21, and the output shaft of the motor 5 is fixedly connected to the worm rod 20.

[0024] During use, the starting motor 5 drives the worm rod 20 to rotate, thereby driving the turbine 19 to rotate, and then driving the traction take-up drum 2 to rotate. Since the turbine 19 and the worm rod 20 are self-locking, that is, the turbine 19 cannot drive the worm rod 20 to rotate, thereby ensuring that the traction take-up drum 2 will not rotate in the opposite direction.

[0025] Among them, an extrusion wheel 8 is provided above the counting wheel 4 , and the extrusion wheel 8 is adapted to the receiving groove 13 . A lifting mechanism acting on the extrusion wheel 8 is provided on the first vertical plate 6 .

[0026] Among them, the lifting mechanism consists of a U-shaped plate 9, a connecting plate 10, an adjusting screw 11 and a guide rod 12. The U-shaped plate 9 is located above the extrusion wheel 8, and the two ends of the extrusion wheel 8 are rotatably connected between the two parallel plates of the U-shaped plate 9. The two ends of the U-shaped plate 9 are fixedly connected with the connecting plates 10. A guide rod 12 is slidably inserted on one connecting plate 10, and the bottom of the guide rod 12 is fixedly connected to the upper end of a first vertical plate 6. An adjusting screw 11 is inserted on the other connecting plate 10. The adjusting screw 11 and the connecting plate 10 are connected by threaded fitting, and the bottom of the adjusting screw 11 is rotatably connected to the upper end of the other first vertical plate 6.

[0027] During use, the adjusting screw 11 is rotated, and with the cooperation of the guide rod 12, the U-shaped plate 9 will move up and down along the axial direction of the adjusting screw 11, thereby adjusting the height of the extrusion wheel 8 and controlling the extrusion wheel 8 to move downward, thereby squeezing the conductive wire placed in the receiving groove 13 of the counting wheel 4, increasing the friction between the conductive wire and the counting wheel 4, and ensuring that there is no relative sliding between the conductive wire and the counting wheel 4. In this way, the value obtained by multiplying the number of revolutions of the counting wheel 4 by the circumference of the receiving groove 13 is always consistent with the length of the conductive wire moved.

[0028] The upper end of the adjusting screw 11 is fixedly connected to a handle, and the outer surface of the handle is frosted.

[0029] Such an arrangement can facilitate the staff to rotate the adjusting screw 11.

[0030] A plurality of fixing holes are respectively provided on both sides of the upper end of the base 1 .

[0031] The device can be fixedly installed by cooperating with the external fixing bolts and the fixing holes.

[0032] The utility model provides a wire head pulling device for conductive wire processing, and the specific working principle is as follows:

[0033] When using, place the conductive wire in Figure 1 As shown in the figure, the starting motor 5 drives the vortex rod 20 to rotate, thereby driving the turbine 19 to rotate, and then driving the traction take-up drum 2 to traction and reel the conductive wire. Since the turbine 19 and the vortex rod 20 are self-locking, that is, the turbine 19 cannot drive the vortex rod 20 to rotate, thereby ensuring that the traction take-up drum 2 will not rotate in the opposite direction. When the traction take-up drum 2 is traction and reeling the conductive wire, the conductive wire will generate an upward pulling force on the tensioning wheel 3, thereby causing the spring 17 to be slightly compressed. The force of the spring 17 to restore its deformation will make the conductive wire in a straight state, thereby facilitating its coating. The counting wheel 4 and the tachometer 7 are provided to count the number of rotations of the counting wheel 4. By multiplying the number of rotations of the counting wheel 4 by the circumference of the receiving groove 13, the moving length of the conductive wire can be obtained, thereby ensuring that the length of the conductive wire wound on the take-up reel 2 each time is within a smaller area, which is convenient for the subsequent packaging and sale of the conductive wire. The lifting mechanism is provided to control the squeezing wheel 8 to squeeze the conductive wire placed in the receiving groove 13 of the counting wheel 4, thereby increasing the friction between the conductive wire and the counting wheel 4 and ensuring that there is no relative sliding between the conductive wire and the counting wheel 4.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
