It is often used in the fields of clothing processing, engineering line erection, etc.

[0003] At the construction site, when we use various insulated wires and optical cables, due to the different inner diameters of the wire reels, they are usually laid out manually. The wire reels cannot be fixed on the pallets, and when workers pull the wire harnesses unevenly, the wire reels are easily displaced, causing the wire reels to fall off and the pallets to overturn. In addition, manual laying of wires is labor-intensive, and long-term concentration on laying wires can easily lead to fatigue, which poses a safety hazard. It is also easy to be negligent when laying wires. Because the wires themselves have a certain torque, the wire reels are easily loose and tangled, affecting construction efficiency and wasting materials. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 As shown, a turntable pay-off device for a wire breaking machine comprises a base 1, a first leg 2 and a second leg 14 are fixedly connected to the side of the base 1, a universal wheel 3 is arranged at one end of the first leg 2, and the arrangement of the universal wheel 3 enables the device to be easily moved, an upper bracket 4 is arranged on the upper part of the base 1, a bearing 9 is arranged between the base 1 and the upper bracket 4, and the arrangement of the bearing 9 enables the upper bracket 4 to rotate around the axis of the base 1, friction plates 8 are arranged on both sides of the bearing 9, and the friction plates 8 have the function of stabilizing the rotation speed of the bearing 9, and the upper bracket 4 is provided with a plurality of bearings. A slide track 5 is fixedly connected to the side of the bracket 4, and a clamp mechanism 6 is provided on the surface of the slide track 5. The clamp mechanism 6 has the function of fixing the wire drum and stabilizing the wire pay-out. A universal wheel 3 is provided at the lower part of the second leg 14, and a bracket 10 is fixedly connected to one end of the second leg 14. An auxiliary wire pay-out mechanism 7 is provided on one side of the bracket 10. The auxiliary wire pay-out mechanism 7 has the function of assisting wire pay-out and reducing the loose knotting of the wire drum. A limiter 11 is provided at one end of the surface of the bracket 10, and a rotating shaft bracket 12 is provided at the other end of the surface of the bracket 10.

[0021] The clamp mechanism 6 includes a crank 61, one end of which is connected to a screw rod 62, and the other end of the screw rod 62 is connected to a bevel gear disc 63. The bevel gear disc 63 is threadedly connected to a clamping plate 64. When the utility model is releasing the wire, the wire drum is placed on the slide track 5. By rotating the crank 61, the screw rod 62 is driven to rotate, and then the bevel gear disc 63 is driven to rotate. The bevel gear disc 63 and the screw rod 62 in other three directions are driven to rotate by the bevel gear disc 63. The rotation of the screw rod 62 in four directions drives the clamping plate 64 to move to the end away from the center. When the clamping plate 64 moves to the wall of the wire drum and no longer moves, the wire drum is fixed at the center of the upper bracket 4.

[0022] The auxiliary wire-releasing mechanism 7 includes a motor 71, one end of the axis of the motor 71 is connected to a first gear 72, the first gear 72 is meshed with a second gear 73, a driving wheel 74 is connected to the axis of the second gear 73, the surface of the bracket 10 is rotatably connected to a shaft 76, one end of the shaft 76 is rotatably connected to a driven wheel 75, the side of the shaft 76 is connected to a first spring 77, the other end of the first spring 77 is fixed to the top of the bracket 10, and the auxiliary wire-releasing mechanism 7 is suitable for wire harnesses of various diameters through the setting of the driven wheel 75. When the utility model releases the wire, the wire harness passes through the limiter 11, the driven wheel 75 is pushed away, and the driven wheel 75 is rotated. The wheel 75 forces the shaft 76 to rotate and puts the first spring 77 in a stretched state, passing the wiring harness through the driven wheel 75 and the driving wheel 74, loosening the driven wheel 75, and under the action of the first spring 77, the shaft 76 leans against the driving wheel 74, so that the driving wheel 74 and the driven wheel 75 clamp the wiring harness, and then the wiring harness passes through the rotating shaft bracket 12, and the starting motor 71 drives the first gear 72 to rotate, and at the same time the first gear 72 drives the second gear 73, and then the second gear 73 drives the driving wheel 74 to rotate, and at the same time the first spring 77 tightly pulls the shaft 76, so that the driven wheel 75 and the driving wheel 74 clamp the wiring harness and rotate together, and the wiring harness can be released, thereby reducing the intensity of manual wiring.

[0023] The limiter 11 includes a frame leg 111, and a roller 112 is arranged between the frame legs 111. Both ends of the roller 112 are rotatably connected to a slider 114. The upper part of the slider 114 is connected to a second spring 113, and the other end of the second spring 113 is fixed to the top of the slide groove of the frame leg 111. The slider 114 slides up and down in the slide groove of the frame leg 111. Through the setting of the second spring 113, the roller 112 has the function of moving up and down, so that the limiter 11 can pass the wire harnesses of different diameters and constrain the position of the wire harnesses to prevent the wire harnesses from escaping from the auxiliary release mechanism 7.

[0024] Working principle: When the device is working, put the wire reel into the slide track 5, use the clamp mechanism 6, turn the crank 61 to drive the screw rod 62 to rotate, drive the bevel gear plate 63 to rotate, and drive the clamp plate 64 to move to the end away from the center. When the clamp plate 64 moves to the inner wall of the coil and no longer moves, the coil is fixed by the clamp plate 64 at the center of the upper bracket 4, so that the wire reel is stable and not easy to fall off, reducing the difficulty of releasing the wire; when starting to release the wire, pass the wire harness through the limiter 11, open the driven wheel 75 so that the wire harness is clamped between the driving wheel 74 and the driven wheel 75, and then pass through the rotating shaft bracket 12, and then turn on the motor 71. Under the action of the motor 71, the first gear 72 is driven to rotate, and at the same time, the first gear 72 drives the second gear 73, and then the second gear 73 drives the driving wheel 74 to rotate. At the same time, the first spring 77 tightly pulls the shaft rod 76, so that the driven wheel 75 on the shaft rod 76 and the driving wheel 74 clamp the wiring harness and rotate together, so that the wiring harness can be released, reducing labor intensity. At the same time, under the friction effect of the friction plate 8 on the bearing 9, the coil is prevented from being over-released and the coil is loose and knotted, reducing the construction intensity of the workers; when the construction of one place needs to be transferred to the next place, the brake device 13 of the universal wheel 3 is opened, and the device can be easily moved.

[0025] It should be noted that the brake device 13 on the universal wheel 3 is a prior art, and the universal wheel 3 has a braking function, which is a common function on the market. Therefore, this technical solution will no longer describe the specific structure and working method of the brake device 13 in detail.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
