[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0025] Combined Figure 1 , a protective film winding device with adjustable fixed tension of the present invention includes a fixing mechanism 1. A protective film low-temperature contact frame 2 for low-temperature flattening of the protective film is sleeved on the fixing mechanism 1. A conveying mechanism 3 for conveying and winding is rotatably sleeved on the fixing mechanism 1. A tension adjusting mechanism 4 for adjusting the tension is slidably sleeved on the fixing mechanism 1. The fixing mechanism 1 includes a chassis 11, side frames 12 fixedly connected to both sides of the chassis 11. A lifting groove 121 is opened on the side frames 12. The protective film low-temperature contact frame 2 includes a heating roller 21 connected between the two groups of side frames 12. A heat insulation rotating ring 22 is rotatably sleeved outside the heating roller 21. The tension adjusting mechanism 4 includes a lifting block 43 slidably arranged in the lifting groove 121. A liftable lifting frame 44 is rotatably connected between the two groups of lifting blocks 43.

[0026] Specifically, the chassis 11 fixedly arranges the two groups of side frames 12. The lifting groove 121 provides guidance for the lifting of the tension adjusting mechanism 4. The heating roller 21 is electrically heated. The heat insulation rotating ring 22 is movably sleeved on the heating roller 21 to transfer heat. The lifting block 43 drives the lifting frame 44 to lift along the lifting groove 121. The tension of the protective film is adjusted under the lifting adjustment of the lifting frame 44. At the same time, the lower end of the lifting frame 44 contacts the heat insulation rotating ring 22 to perform low-temperature adaptability adjustment on the protective film. The setting of the lifting frame 44 enables this winding device to adapt to the winding requirements of protective films with different materials and different thicknesses. The low-temperature contact of the protective film low-temperature contact frame 2 can reduce thermal damage and help the protective film adhere tightly to the surface of electronic products.

[0027] The present invention will be further described below in conjunction with embodiments.

[0028] Embodiment 1:

[0029] Combined Figures 2 - 5 , on both sides of the heat insulation rotating ring 22, side top frames 221 are rotatably sleeved. The diameter of the side top frames 221 is larger than the middle diameter of the heat insulation rotating ring 22 and is arranged in cooperation with the lifting frame 44. The downward pressure of the lifting frame 44 can make the protective film contact the heat insulation rotating ring 22.

[0030] The conveying mechanism 3 includes a first rotating rod 31, a second rotating rod 32, a buckling rod 33, and a steering rod 34 connected between two sets of side frames 12. The first rotating rod 31 is arranged at the upper end, the second rotating rod 32 and the buckling rod 33 are arranged side by side at the lower end, and the steering rod 34 is arranged at the upper end. The protective film passes through the first rotating rod 31, the second rotating rod 32, the buckling rod 33, and the steering rod 34, and moves smoothly and is redirected in sequence, so that the protective film can be flat when passing through the tension adjusting mechanism 4. Moreover, the arrangement of winding back and forth between the first rotating rod 31, the second rotating rod 32, the buckling rod 33, and the steering rod 34 also provides a certain tension for the protective film.

[0031] The conveying mechanism 3 further includes a winding frame 35 connected between two sets of side frames 12, and a driving cylinder 36 connected to one end of the winding frame 35. The driving cylinder 36 drives the winding frame 35 to rotate to achieve winding, and the protective film on the winding frame 35 is transmitted through the lifting frame 44.

[0032] Positioning support frames 351 are arranged at both ends of the winding frame 35. Grooves for placing the winding frame 35 are provided on the positioning support frames 351. The positioning support frames 351 realize the support and positioning of the winding frame 35. The winding frame 35 is inserted into the side frame 12, and one end of the winding frame 35 is clamped to the output end of the driving cylinder 36.

[0033] Embodiment 2:

[0034] Combined with Figure 3 the tension adjusting mechanism 4 further includes a guide rod 41 movably inserted into the side frame 12. There are two sets of guide rods 41. A cylinder part 42 is connected to the upper end of one set of guide rods 41. The cylinder part 42 drives the lifting block 43 to move up and down. The guide rod 41 is slidably clamped in the side frame 12 to achieve guiding.

[0035] The shapes of the lifting block 43 and the lifting groove 121 match each other. The matching setting of the lifting groove 121 and the lifting block 43 prevents lifting deviation.

[0036] The middle part of the lifting frame 44 has a thicker diameter, and the two ends are thinner. The middle part of the heat insulation rotating ring 22 has a thinner diameter, and the side top frames 221 at both ends of the heat insulation rotating ring 22 have a thicker diameter. The lifting frame 44 and the side top frames 221 are matched with each other, so that the upper and lower ends of the protective film can be respectively attached to the lifting frame 44 and the heat insulation rotating ring 22.
