[0002] The existing pay-off stand is generally composed of a rack, a support and a pay-off wheel, but the pay-off stand of this structure is generally pulled by subsequent wire drawing equipment, which is a passive pay-off method, so as the weight of the wire is reduced, the pulling force of the wire drawing equipment is the same, and the same pulling force will pull more wire from the wire coil, thereby causing the wire to be loose and unable to maintain a straight state, and the wire may also be wound, which may also cause uneven winding of the wire. In addition, the existing pay-off stand is troublesome to replace the wire coil and cannot automatically control the pay-off speed.

[0003] Therefore, the prior art still needs to be improved. SUMMARY

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-5As shown, this invention discloses a high-precision digital detonator network cable winding automatic unwinding device, which includes: a base 1, a handle assembly 2, an active roller assembly 3 for unwinding, a motor drive mechanism 4, a wire wheel mechanism 5, and an electrical control box 6. The handle assembly 2 is rotatably mounted on one end of the base 1, and the active roller assembly 3 is mounted in the U-shaped slot 20 of the handle assembly 2. The wire wheel mechanism 5 is fixed on the bottom plate 10 at the other end of the base 1. The electrical control box 6 is mounted on the front side of the base 1, and the handle assembly 2 can be locked by a pin on the support rod 60 of the electrical control box 6. The motor drive mechanism 4 is mounted on the rear side of the base 1 and is used to drive the active roller assembly 3. A guide roller 7 is also mounted on the other end of the base 1. The wire wheel mechanism 5 includes a tension sensor 8 for detecting the tension of the wire wheel in the wire wheel mechanism. The tension sensor 8 transmits the detected wire wheel tension to the electrical control box 6. The electrical control box 5 is used to control the motor drive mechanism 4.

[0023] This invention uses a tension sensor to detect the tension in the spool mechanism and transmits the detected tension to the electrical control box. The control box then controls the rotation speed of the motor drive mechanism, which in turn controls the active unwinding speed of the active roller assembly. This ensures that the tension in the spool mechanism remains within a set reference range. The tension sensor provides real-time feedback on the detected tension value, allowing the control box to adjust the unwinding speed of the motor drive mechanism. The motor drive mechanism enables active unwinding and effectively prevents the spool from tangling during the unwinding process. Furthermore, a handle assembly can be flipped up at one end of the base. After the spool is unwound, it can be flipped outwards to disassemble the entire active roller assembly for easy and quick spool replacement.

[0024] like Figure 1 As shown, one end of the base 1 is provided with a handle slot 11 for installing the handle assembly. The handle assembly 2 is installed on the base 1 by bolts 9, so the handle assembly can be flipped relative to the base, which facilitates the disassembly of the active roller assembly and the replacement of the coil, making the replacement of the coil easier and eliminating the need for manual lifting of the coil.

[0025] like Figure 2 As shown, the handle assembly 2 includes: a handle 21, a U-shaped plate 22 and a handle cover 23. The handle 21 and the U-shaped plate 22 are an integral structure. The U-shaped plate 22 is provided with a U-shaped slot 20. The handle cover 23 is fixed to the outer side of the U-shaped plate 22 by screws. The handle 21 is also provided with a locking plate 12 for locking. The locking plate 12 is provided with a locking hole 120.

[0026] With the above structure, the U-shaped slot set by the U-shaped plate can better install and disassemble the active roller assembly, while the locking plate can better lock the handle assembly to the control box to prevent the handle assembly from flipping outward, and the locking hole can achieve a quick locking effect.

[0027] Preferably, such as Figure 3 As shown, the active roller assembly 3 includes an active roller 30 and a driven gear 31. The driven gear 31 is fixed to one end of the active roller 30. Active bearings 32 are respectively installed at both ends of the active roller 30. A positioning cone group 33 for locking the wire coil is also installed on the active roller 30. A threaded structure 300 is also provided at the other end of the active roller 30. The active roller 30 is placed in the U-shaped groove 30 through the active bearings 32, and the active bearings 32 are locked in the U-shaped groove 30 by the locking screws 13.

[0028] With the above structure, the active roller of the present invention can be installed in the U-shaped slot via the active bearing, and can be quickly locked and disassembled by the locking screw. The driven gear meshes with the active gear, enabling the active gear of the motor drive mechanism to drive the active roller to rotate. Furthermore, the positioning cone assembly enables the positioning of the wire coil placed on the active roller. Preferably, such as Figure 3 As shown, the main positioning cone group 33 includes a fixed cone 14 and an adjusting cone 15. The fixed cone 14 is fixed to one end of the drive roller 30, and the adjusting cone 15 is installed on the threaded structure 300 of the main roller 30. By installing the adjusting cone on the threaded structure, the distance between the adjusting cone and the fixed cone can be controlled. The adjustment is achieved through the threaded structure, so it can meet the needs of different types of wire coils.

[0029] Preferably, such as Figure 1 As shown, the two ends of the guide roller 7 are mounted on the base 1 through bearing seats 16, so the guide roller can rotate relative to the base to guide the laying of the line.

[0030] Preferably, such as Figure 4 As shown, the motor drive mechanism 4 includes: a gear seat 40 fixed to the rear side of the base 1, a drive gear 41, a servo motor 42, a reduction gearbox 43, a drive shaft 44, and a wire feeding bearing 45. The wire feeding bearing 45 is installed on the inner side of the gear seat 40, the drive shaft 44 is installed in the wire feeding bearing 45, the drive gear 41 is fixed on the drive shaft 44, one end of the drive shaft 44 is connected to the reduction gearbox 43, the reduction gearbox 43 is fixed on the outer side of the gear seat 40, the servo motor 42 is connected to the reduction gearbox 43, the servo motor 42 drives the drive shaft 55 to rotate through the reduction gearbox 43, thereby driving the drive gear 41 to rotate, and the drive gear 41 meshes with the driven gear 31.

[0031] With the above structure, the present invention connects the servo motor to the gearbox, and then the speed of the drive shaft can be controlled by the gearbox. The drive shaft can drive the active gear to rotate, and then drive the driven gear to rotate, thereby achieving the purpose of active wire feeding and controlling the wire feeding speed.

[0032] Preferably, such as Figure 5 As shown, the thread wheel mechanism 5 includes: a thread wheel bracket 50, a slide rail 51, a slider 52, an upper thread wheel assembly 53, and a lower thread wheel assembly 54. The slide rail 51 is fixed on the thread wheel bracket 50, and the bottom of the thread wheel bracket 50 is fixed to the base plate 10 of the base 1 by screws. The lower thread wheel assembly 54 is mounted on a lower thread wheel shaft 56 through a thread wheel bearing 55, and one end of the lower thread wheel shaft 56 is fixed to the slider 52. Both the upper thread wheel assembly 53 and the lower thread wheel assembly 54 are composed of multiple single thread wheels 17, and the single thread wheels 17 rotate independently of each other. The upper thread wheel assembly 53 is mounted on an upper thread wheel shaft 57 through a thread wheel bearing 55, and one end of the upper thread wheel shaft 57 is fixed to the upper part of the thread wheel bracket 50.

[0033] With the above structure, the lower wire wheel assembly can move up and down on the slide rail via a slider, while the wires are intertwined and wound on the single wire wheels between the upper and lower wire wheel assemblies. Each single wire wheel is independent of the others, so it can rotate on its own. The single wire wheel can rotate relative to the upper or lower wire wheel axle through the wire wheel bearing.

[0034] Preferably, such as Figure 5 As shown, the tension sensor 8 is fixed to the lower part of the roller bracket 50 and located below the slide rail 51; the tension sensor 8 is connected to the slider 52 through the tension spring 100, so the tension sensor can detect the tension of the lower roller assembly and ensure that the tension of the lower roller assembly is within the set tension reference value range.

[0035] Preferably, such as Figure 1 As shown, the electrical control box 6 is provided with a support rod 60, the bottom of which is fixed to the base 1. An elastic pin 18 is also installed on the support rod 60. The elastic pin 18 is installed in the pin sleeve 19 by a return spring. The pin sleeve 19 is fixedly connected to the support rod 60. The end of the elastic pin 18 that is inserted into the locking hole 120 is provided with an inclined surface. When the locking plate 12 moves backward, it can squeeze the elastic pin 18. The elastic pin 18 retracts and then inserts into the locking hole 120 to achieve locking.

[0036] This invention uses a tension sensor to detect the tension of the lower spool of the spool mechanism and feeds it back to the electrical control box. The control box then controls the servo motor of the motor drive mechanism to control the unwinding speed of the active roller, ensuring that the tension of the lower spool is within the set reference value. This achieves the function of active unwinding and controls the unwinding speed, effectively preventing the problem of wire tangling caused by excessive pulling force. Since the handle assembly is rotatably mounted on the base, when it is necessary to replace the spool, it can be flipped outwards. Then, the active roller assembly can be completely removed from the U-shaped slot, the spool can be replaced, and finally, it can be reinstalled in the U-shaped slot of the handle assembly and fixed. The handle assembly can then be flipped upwards and locked. This makes spool replacement simpler, less strenuous, and faster.

[0037] The above are merely preferred embodiments of the present invention, and should not be construed as limiting the scope of the present invention. It should be noted that for those skilled in the art, any modifications or equivalent substitutions to the technical solutions of the present invention without creative effort do not depart from the protection scope of the technical solutions of the present invention.
