[0031] As shown in the accompanying drawings of the specification Figures 1-6As shown in the figure, the utility model provides a wire unwinding device for wire and cable irradiation, which includes a workbench 1. Above one side of the workbench 1, a rewinder 2 is arranged. Along the wire outlet direction of the rewinder 2, a wire arranging mechanism and a tension adjusting mechanism are successively arranged. The tension adjusting mechanism is provided with two sets of fixedly arranged extrusion rollers 9 that move relative to each other. Compared with the existing tension pulley adjustment method, the adjustment mechanism of this application uses two sets of extrusion rollers 9 to move in opposite / towards directions. Specifically in implementation, the two sets of extrusion rollers 9 approach the wire and cable to squeeze the wire and cable, making the wire and cable stretched in a Z shape. Compared with the rotating extrusion rollers 9 in the prior art, the extrusion rollers 9 in this application are fixedly arranged without rotation and use the extrusion method. With the extrusion rollers 9 squeezing back and forth repeatedly, a greater tensile stress can be provided to the wire and cable, thereby improving the tension adjustment effect of the wire and cable and avoiding the slack failure of the wire and cable outlet;

[0032] Specifically, as Figure 2 shown, the tension adjusting mechanism includes an adjusting plate 3 fixedly arranged at the top of the other side of the workbench 1. In the middle of the side wall of the adjusting plate 3, a gear 4 is arranged. Inside the gear 4, a driving shaft 5 is fixedly arranged. At the rear end of the driving shaft 5, a first motor 6 is arranged. On both sides of the gear 4, a rack 7 meshed with it is symmetrically arranged. At the front end of each rack 7, an adjusting rod 8 is arranged. On both adjusting rods 8, extrusion rollers 9 are arranged. The extrusion rollers 9 are respectively arranged below one adjusting rod 8 and above the other adjusting rod 8 on the other side. Inside both sides of the side wall of the adjusting plate 3, guide grooves 10 are opened. Inside the guide grooves 10, guide rods 11 are fixedly arranged. The guide rods 11 are slidably connected with guide blocks 12 fixedly connected with the racks 7. Specifically in implementation, in the initial state, the wire and cable is between the two sets of extrusion rollers 9. Then, the first motor 6 is started to control the driving shaft 5 to drive the gear 4 to rotate circumferentially on the plate surface of the adjusting plate 3. As the gear 4 rotates forward and backward, the two racks 7 on its two sides are controlled to move in the same / opposite directions. As the racks 7 move, the corresponding extrusion rollers 9 connected to them move synchronously, respectively squeezing / loosening the wire and cable. The stretching of the wire and cable is realized by squeezing the wire and cable. During the movement of the extrusion rollers 9, the guide blocks 12 in the guide grooves 10 slide up and down along the rod walls of the guide rods 11 to provide guidance and stability for them, ensuring the smooth up and down movement of the extrusion rollers 9.

[0033] In this embodiment, as Figure 1 、 Figure 4As shown in the figure, the wire arranging mechanism includes a working plate 13 movably arranged at the top end of the middle part of the workbench 1. A working cavity is formed inside the front end of the working plate 13. A second motor 14 is arranged on one side of the bottom end of the working cavity. The output shaft of the second motor 14 faces upward and is fixedly connected with a threaded rod 15. A threaded block 16 is threadedly connected to the threaded rod 15. A sliding block 17 is arranged on one side of the threaded block 16. A first sliding rod 18 slidably connected with the sliding block 17 is fixedly arranged on the other side of the bottom end of the working cavity. By starting the second motor 14 to drive the threaded rod 15 to rotate, under the guiding action of the sliding block 17 sliding along the first sliding rod 18, the threaded block 16 moves up and down along the central axis direction of the threaded rod 15, thereby adjusting the working height of the wire arranging mechanism according to the working conditions.

[0034] Specifically, as Figure 5 shown, a fixed shaft 19 is arranged at the front end of the threaded block 16. The fixed shaft 19 is fixedly connected with a wire arranging wheel 20. A plurality of wire arranging grooves 21 are equidistantly arranged on the surface of the wire arranging wheel 20. A buffer pad 22 is arranged inside each wire arranging groove 21. The surface of the existing wire arranging wheel 20 is smooth, and the wire arranging effect is average. In the utility model, by arranging a plurality of wire arranging grooves 21 on the surface of the wire arranging wheel 20, when the cable is wound on the surface of the wire arranging wheel 20, it can be wound sequentially along the wire arranging grooves 21, avoiding the cable from being wound or knotted during winding, ensuring the orderly wire arranging of the wire arranging wheel 20, and arranging the buffer pad 22 in the wire arranging grooves 21 to avoid the tensile force during cable winding from directly generating prestress on the inner wall of the wire arranging grooves 21 and causing wear, thereby improving the use safety of the wire arranging grooves 21.

[0035] As a preferred scheme of the utility model, preferably, as Figure 4 shown, a pair of sliding plates 23 are arranged at the rear end of the top of the workbench 1. A second sliding rod 24 slidably connected with the working plate 13 is fixedly arranged between the pair of sliding plates 23. A hydraulic push rod 25 connected with the working plate 13 is arranged at the bottom end of one group of sliding plates 23. By starting the hydraulic push rod 25 on the sliding plate 23, it is pushed to horizontally slide the working plate 13 along the outer wall of the second sliding rod 24, thereby adjusting the horizontal position of the wire arranging wheel 20.

[0036] As a preferred scheme of the utility model, preferably, as Figure 6As shown in the figure, buffer columns 26 are provided at the four corners of the bottom end of the unwinder 2. A buffer cylinder 27 is provided below the buffer columns 26. A buffer hole 28 adapted to the buffer columns 26 is formed on the top surface of the buffer cylinder 27. The buffer cylinder 27 is slidably connected to the buffer columns 26 through the buffer holes 28. A buffer plate 29 fixedly connected to the buffer columns 26 is slidably arranged inside the buffer cylinder 27. A buffer spring 30 connected to the inner bottom wall of the buffer cylinder 27 is provided below the buffer plate 29. When the unwinder 2 is working, corresponding working vibration loads will be generated. A relatively large vibration amplitude will affect the cable winding and unwinding work of the equipment itself. In this regard, in the present utility model, the buffer columns 26 provided at the bottom end thereof slide up and down in the buffer cylinder 27 and cooperate with the elastic expansion and contraction of the buffer spring 30, so as to slow down and disperse the vibration loads, reduce the influence brought by the loads to the unwinder 2 itself, and improve the anti-vibration effect of the unwinder 2.

[0037] As a preferred solution of the present utility model, in order to reduce the mold material amount and economic cost of the workbench 1, preferably, as Figure 1 shown, a long strip-shaped material reduction cavity 31 is formed inside the front end of the workbench 1.

[0038] Working principle:

[0039] As shown in the attached drawings of the specification Figures 1-6 shown, first, the cable in the unwinder 2 is led out of the unwinder 2, and winds around the wire arranging wheel 20 in multiple turns along the wire arranging groove 21 and then winds out from the wire arranging wheel 20. The wound cable passes through between the pressing rollers 9 and is led to the irradiation area. Then, the unwinder 2 is started for wire releasing work. The cable passes through the wire arranging wheel 20 and the pressing rollers 9 in sequence to the irradiation area. The wire arranging wheel 20 and the wire arranging groove 21 play a role in guiding the transmission direction of the cable. Through the relative movement between the pressing rollers 9, the cable can be extruded to increase its tensile strain force, so as to keep it always taut and avoid slack. The forward / backward movement of the pressing rollers 9 is mainly realized by starting the first motor 6 to drive the driving shaft 5 to rotate and the gear 4 to engage with the rack 7. When the wire arranging wheel 20 is working, the height direction adjustment can be carried out by starting the second motor 14 to drive the threaded rod 15 to rotate, and the wire arranging wheel 20 can be vertically lifted and lowered. In addition, the horizontal position of the wire arranging wheel 20 can be adjusted by starting the hydraulic push rod 25.

[0040] The above are only the preferred embodiments of the present utility model, and the parts not described in the present utility model can be realized by adopting or referring to the existing technologies. Of course, the above description is not a limitation to the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence scope of the present utility model should also belong to the protection scope of the present utility model.
