[0029] In view of the problem that the adhesive film material is easy to peel off and affect the flat winding of the traction film due to the change of tension in the UV protective film peeling and winding process, such as Figures 1-4As shown, this is a preferred embodiment of the UV protective film production peeling and winding device of the present invention. The peeling and winding device includes a frame 1, two peeling rollers 2, a winding roller 4 and a first drive mechanism 5 mounted on the frame 1. The first drive mechanism 5 is used to drive the winding roller 4 to rotate. At least one first guide roller 6, a second guide roller 7 and a tensioning mechanism 8 are provided in front of the peeling roller 2. The tensioning mechanism 8 includes a second drive mechanism 81, a swing bracket 82, a third guide roller 83 and a fourth guide roller 84. A first positioning shaft 85 is provided between the swing bracket 82 and the frame 1. The second drive mechanism 81 is used to drive the swing bracket 82 to swing back and forth around the first positioning shaft 85. The third guide roller 83 and the fourth guide roller 84 are respectively located at both ends of the swing bracket 82. At least one set of fifth guide rollers 9 and sixth guide rollers 10 are provided behind the peeling roller 2 and are staggered. The fifth guide roller 9 is located between the peeling roller 2 and the winding roller 4.

[0030] The working principle of the above-mentioned peeling and winding device includes:

[0031] like Figures 1-3 As shown, the UV protective film 11 with traction film can be guided and conveyed into the device from the first guide roller 6 on the side, and then sequentially passes around the fifth guide roller 9, the second guide roller 7, and the sixth guide roller 10 to enter between the two peeling rollers 2. The UV protective film 11 with traction film is peeled and separated here. The traction film 13 is wound onto the take-up roller 4 through the fifth guide roller 9. The UV protective film 12 with adhesive can be conveyed to the next process through the sixth guide roller 10, such as to the slitting process. The take-up roller 4 is driven by the first drive mechanism 5 to take up the traction film 13, and the traction film 13 is continuously wound onto the take-up roller 4, which can continuously drive the UV protective film 11 with traction film to be fed and peeled.

[0032] like Figure 4 As shown, as peeling progresses, the diameter of the traction film roll 14 on the take-up roller 4 continuously increases. The second drive mechanism 81 drives the swing bracket 82 to swing around the first positioning shaft 85, which can synchronously change the position of the third guide roller 83 and the fourth guide roller 84 at both ends. For example, the distance between the third guide roller 83 and the first guide roller 6 and the second guide roller can be increased, and the distance between the fourth guide roller 84 and the peeling roller 2 can be increased. This can adjust the tension of the passing UV protective film, thereby adjusting the tension of the traction film 13 and the adhesive UV protective film 12 during peeling, thus improving the problem of easy loosening and adhesion of the adhesive film material. By adjusting the tension of the film material during peeling, the reliability of the flat winding of the traction film 13 can be improved. Similarly, the second drive mechanism 81 can also drive the swing bracket 82 to swing back and reset, so that the third guide roller 83 and the fourth guide roller 84 can be reset for re-operation or tension adjustment.

[0034] Further, one of the stripping rollers 2 is connected with a third driving mechanism 15, and the third driving mechanism 15 is used to drive the stripping roller 2 to reciprocate relative to the other stripping roller 2; for example, as shown in Figure 1 and Figure 4 , the third driving mechanism 15 comprises a third cylinder 151, the main body of the third cylinder 151 is horizontally fixed on the rack 1, and the cylinder rod of the third cylinder 151 is connected with one of the stripping rollers 2 through a support 152, so that the stripping roller 2 can be driven to reciprocate horizontally relative to the other stripping roller 2 through the extension and contraction of the cylinder rod, the spacing between the two stripping rollers 2 is adjusted, the spacing is more conveniently increased at the beginning to put in the UV protective film, and the spacing is more conveniently reduced to adjust the stripping clamping force of the stripping roller 2 on the UV protective film.

[0035] Further, the second driving mechanism 81 comprises a first cylinder 811, the tail end of the first cylinder 811 is hinged to the rack 1, and the cylinder rod of the first cylinder 811 is hinged to the swing support 82; for example, as shown in Figures 1-2 , the cylinder rod of the first cylinder 811 is connected between the first positioning shaft 85 and the fourth guide roller 84, the cylinder rod of the first cylinder 811 can drive the swing support 82 to swing clockwise around the first positioning shaft 85 when being elongated, as shown in Figure 4 , the cylinder rod of the first cylinder 811 can pull the swing support 82 to swing counterclockwise around the first positioning shaft 85 when being contracted, and the main body of the first cylinder 811 is adaptively deflected through the hinge, this structure is simple and convenient to drive and control.

[0036] Further, including two second guide rollers 7, the third guide roller 83 is located between the first guide roller 6 and the adjacent second guide roller 7, the fourth guide roller 84 is located between the two second guide rollers 7: for example, as shown in Figure 1 and Figure 4 The first guide roller 6, the second guide roller 7 and the fifth guide roller 9 are all two, the UV protective film 11 with the traction film can be guided and conveyed into the device from the two first guide rollers 6 on the side in turn, and then pass through the fifth guide roller 9, one of the second guide rollers 7, the sixth guide roller 10, the other second guide roller 7 into the two stripping rollers 2, the traction film 13 is wound on the winding roller 4 through the two fifth guide rollers 9, then the swing bracket 82 swings, the spacing between the fourth guide roller 84 and the two second guide rollers 7 can also be adjusted to adjust the conveying tension, and the second guide roller 7 close to the two stripping rollers 2 also makes the entering direction of the UV protective film before stripping more reliable.

[0037] Further, the smoothing mechanism 3 is arranged between the fifth guide roller 9 and the winding roller 4, the smoothing mechanism 3 includes a fourth driving mechanism 31, a smoothing bracket 32 and a smoothing roller 33, one end of the smoothing bracket 32 is provided with a second positioning shaft 34 between the rack 1, the other end of the smoothing bracket 32 is connected with the smoothing roller 33, and the fourth driving mechanism 31 is used for driving the smoothing bracket 32 to reciprocatingly deflect around the second positioning shaft 34; for example, as shown in Figure 1 and Figure 3 When the winding diameter of the traction film 13 is small, the fourth driving mechanism 31 drives the smoothing bracket 32 to deflect around the second positioning shaft 34, which can make the smoothing roller 33 close to the traction film roll 14 on the winding roller 4, and the traction film 13 entering the winding roller 4 from the fifth guide roller 9 is further flattened by the smoothing roller 33; as shown in Figure 4 With the increase of the diameter of the traction film roll 14, the fourth driving mechanism 31 can drive the smoothing bracket 32 to deflect around the second positioning shaft 34 to ensure the proper position of the smoothing roller 33, which can further improve the stability of the traction film 13 winding and the conveying tension.

[0038] Further, the fourth driving mechanism 31 includes a second cylinder 311, the tail end of the second cylinder 311 is hinged with the rack 1, and the cylinder rod of the second cylinder 311 is hinged with the smoothing bracket 32; for example, as shown in Figure 1 and Figure 3 The second cylinder 311 is installed on the rack 1 below the smoothing bracket 32, then the cylinder rod of the second cylinder 311 can pull the smoothing bracket 32 to deflect clockwise around the second positioning shaft 34, as shown in Figure 4As shown, the cylinder rod elongation of the second cylinder 311 can push the flattening support 32 to deflect counterclockwise around the second positioning shaft 34, while the main body of the second cylinder 311 is adaptively deflected relative to the hinge position of the frame 1 and the flattening support 32, so that the flattening support 32 can be quickly driven to reciprocatingly deflect, and the structure is simple and the operation is fast and stable.

[0039] Further, the flattening support 32 is provided with at least one seventh guide roller 35. Figure 1 and Figure 3 As shown, the seventh guide roller 35 is arranged between the hinge position of the second cylinder 311 and the flattening roller 33, so that the traction film 13 passing through the fifth guide roller 9 can first pass around the seventh guide roller 35 and then be conveyed between the flattening roller 33 and the winding roller 4. Figure 4 As shown, with the increase of the deflection angle of the flattening support 32 and the horizontal plane, the position of the seventh guide roller 35 is raised, so that the direction and contact surface of the traction film 13 entering the flattening roller 33 can be changed, the flattening effect is further improved, the influence on the conveying tension is reduced, the winding stability of the traction film 13 is improved, and the stability and efficiency of the stripping are further improved.
