[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-6 As shown, this utility model provides an unwinding device for processing paint stickers with tension adjustment, including an unwinding machine 1. A frame plate 11 is fixedly installed on one side of the unwinding machine 1. Two first guide rollers 12 and two second guide rollers 13 are rotatably installed on the frame plate 11. By setting the first guide rollers 12 and the second guide rollers 13, when the rolled paint sticker 10 is installed on the winding roller of the unwinding machine 1, the paint sticker 10 passes between the two first guide rollers 12 and the two second guide rollers 13 as the unwinding machine 1 unwinds, thus guiding the unwinding of the paint sticker 10. A tension adjustment mechanism 2 is provided on the frame plate 11. By setting the tension adjustment mechanism 2, the tension of the paint sticker 10 during the unwinding process can be adjusted to ensure that the paint sticker 10 is transported smoothly and to avoid wrinkles or stretching deformation of the paint sticker 10. The tension adjustment mechanism 2 includes a roller tension sensor 21. The roller tension sensor 21 measures the tension of the paint sticker 10 by applying force. An L-shaped bracket 23 is fixedly installed below the frame plate 11. A U-shaped bracket 24 is provided on the L-shaped bracket 23. The roller tension sensor 21 is detachably mounted on the U-shaped bracket 24. A lifting frame 25 is fixedly installed on the lower surface of the U-shaped bracket 24. The lifting frame 25 is slidably mounted on the L-shaped bracket 23. A servo motor 26 is fixedly installed at one end of the L-shaped bracket 23. The servo motor 26 is connected to the roller tension sensor 21. The tension sensor 21 is connected to the signal. When the roller tension sensor 21 measures the tension of the paint sticker 10, it transmits the signal to the servo motor 26 to control the servo motor 26 to rotate in the forward or reverse direction. The drive output end of the servo motor 26 is fixedly equipped with a lead screw 27. The lead screw 27 passes through the lifting frame 25 and is threadedly connected to the lifting frame 25. When the servo motor 26 rotates, the drive shaft of the servo motor 26 can make the lead screw 27 rotate. The lead screw 27 can drive the lifting frame 25 to rise and fall vertically. The lifting frame 25 can make the roller tension sensor 21 rise and fall vertically through the U-shaped bracket 24.

[0023] A slide rail 28 is fixedly installed on one side of the L-shaped fixed frame 23. A sliding block 29 is slidably installed on one end of the slide rail 28. A connecting plate 3 is fixedly installed on one side of the sliding block 29. One end of the connecting plate 3 is fixedly installed on one side of the lifting frame 25. By setting the slide rail 28, the sliding block 29 and the connecting plate 3, the sliding block 29 can slide vertically along the slide rail 28. Thus, the connecting plate 3 can guide the lifting frame 25 vertically, so that the lifting frame 25 can maintain vertical lifting.

[0024] The U-shaped bracket 24 is equipped with a mounting assembly 4, which includes a lower limit ring 41 and an upper limit ring 42. Two lower limit rings 41 and two upper limit rings 42 are provided. The upper limit ring 42 is hinged to one end of the lower limit ring 41. Anti-slip pads 43 are fixedly installed on the inner walls of both the lower limit ring 41 and the upper limit ring 42. The outer wall of the roller tension sensor 21 is in contact with the anti-slip pads 43. By setting the lower limit ring 41, the upper limit ring 42, and the anti-slip pads 43, when the upper limit ring 42 is flipped downwards and fixed to the lower limit ring 41, the roller tension sensor 21 can be fixed. The anti-slip pads 43 can improve the stability between the roller tension sensor 21 and the lower limit rings 41 and the upper limit rings 42. The roller tension sensor 21 passes through both lower limit rings 41 and both upper limit rings 42. Both the lower limit ring 41 and the upper limit ring 42 are fixedly provided with ear plates 44 at their other ends. Each pair of adjacent ear plates 44 is threaded with a locking bolt 45. By providing the locking bolt 45, the upper limit ring 42 can be fixed on the lower limit ring 41. Both ends of the U-shaped bracket 24 are provided with slots 46. The end of the roller tension sensor 21 is movably disposed in the slot 46. The inner wall of the slot 46 is fixedly provided with a U-shaped rubber pad 47. The end of the roller tension sensor 21 is in movable contact with the inner wall of the U-shaped rubber pad 47. By providing the slot 46 and the U-shaped rubber pad 47, after the end of the roller tension sensor 21 enters the interior of the slot 46, the end of the roller tension sensor 21 contacts the interior of the U-shaped rubber pad 47, which can support both ends of the roller tension sensor 21.

[0025] The U-shaped bracket 24 is provided with a slide groove 48. Two sliders 49 are slidably mounted on the inner wall of the slide groove 48. A connecting rod 5 is fixedly mounted on the upper surface of each slider 49. One end of the connecting rod 5 is fixedly connected to the outer wall of the lower limit ring 41. A double-ended screw 51 is rotatably mounted on the U-shaped bracket 24. The double-ended screw 51 passes through the slide groove 48 and is threadedly rotatably connected to the two sliders 49. A rotating handle 52 is fixedly mounted on one end of the double-ended screw 51. By rotating the rotating handle 52, the rotating handle 52 can... The double-ended screw 51 can rotate, and the double-ended screw 51 can drive the two sliders 49 to slide towards each other or away from each other on the inner wall of the groove 48. The sliders 49 can move the lower limit ring 41 and the upper limit ring 42 horizontally through the connecting rod 5, so that the two lower limit rings 41 and the two upper limit rings 42 can move towards each other or away from each other. When the topcoat sticker 10 is located between the two upper limit rings 42, the topcoat sticker 10 can also be limited to prevent the topcoat sticker 10 from shifting.

[0026] Working principle: When it is necessary to unwind the roll of topcoat sticker 10 on the unwinder 1, the operator first loosens the two locking bolts 45, and then manually rotates the rotating handle 52 to rotate the double-headed screw 51. The double-headed screw 51 drives the two sliders 49 to slide towards each other or away from each other on the inner wall of the slide groove 48. The two sliders 49 move the two lower limit rings 41 and the two upper limit rings 42 horizontally through the two connecting rods 5. Adjust the distance between the two upper limit rings 42 so that the distance between the two upper limit rings 42 is adapted to the width of the topcoat sticker 10. Then tighten the two locking bolts 45. As the uncoiling machine 1 operates, the uncoiled topcoat sticker 10 passes between the two first guide rollers 12 and the two second guide rollers 13. At the same time, the topcoat sticker 10 contacts the upper part of the roller tension sensor 21, and the side of the topcoat sticker 10 contacts the side of the upper limit ring 42. The two upper limit rings 42 limit the topcoat sticker 10 to prevent the topcoat sticker 10 from deviating during the uncoiling process. Meanwhile, the roller tension sensor 21 measures the tension of the topcoat sticker 10 by applying force. If the tension is too high or too low, the roller tension sensor 21 transmits the signal to the servo motor 26 and controls the servo motor 26 to rotate in both directions. The servo motor 26 causes the lead screw 27 to rotate, and the lead screw 27 drives the lifting frame 25 to move vertically up and down. The lifting frame 25 uses the U-shaped bracket 24 to make the roller tension sensor 21 move vertically up and down, thereby adjusting the tension of the topcoat sticker 10 during the unwinding process, ensuring that the topcoat sticker 10 is transported smoothly and avoiding wrinkles or stretching deformation of the topcoat sticker 10.
