Description

Technical Field

[0001] The utility model relates to the technical field of film flattening, in particular to a protective film flattening device. Background Art

[0002] The protective film has a flattening process in the production and processing. Most of the existing flattening rollers are flat rollers. Wrinkles are prone to appear in the middle of the protective film during the transmission process, affecting the quality of the protective film; or the flattening roller is a curved roller, but the flattening roller cannot be adjusted. Once wrinkles appear during the flattening process, wrinkles will continue to appear for a long period of time, affecting the quality of the protective film.

[0003] The patent with announcement number CN212475477 U discloses a protective film flattening device, including a frame, a flattening roller, and an adjusting mechanism; the flattening roller is fixed on the frame; the adjusting mechanism is arranged on both sides of the flattening roller; the adjusting mechanism is fixed on both sides of the frame; the protective film is flattened by the flattening roller, the curvature of the flattening roller is adjusted by adjusting the internal structure lead screw I of the flattening roller, and the distance between the flattening roller and the tensioning roller is adjusted by moving the flattening roller as a whole through the flattening roller adjusting mechanism. The utility model can flatten the protective film conveniently and efficiently, the protective film has a good flattening effect, and wrinkles are not easy to appear in the middle. When wrinkles appear, the flattening roller can be quickly adjusted to make the wrinkles disappear.

[0004] The above patent achieves a better flattening effect of the protective film by adjusting the curvature of the flattening roller by adjusting the internal structure screw I of the flattening roller. However, this structure is suitable for softer protective films. For example, when flattening the protective film in the northern winter, when flattening a harder protective film, it cannot flatten the wrinkled protective film in time, affecting the quality of the protective film.

[0025] Please refer to 1-3, a protective film flattening device, including a rotating shaft 1, two rotating shafts 1 are rotatably provided with screw rods 2, and the two rotating shafts 1 are respectively located at the two ends of the screw rods 2, a stabilizing plate 6 is movably sleeved on the middle position of the screw rod 2, threads are provided on both sides of the screw rod 2 and are reverse threads to each other, and nuts 7 are spirally connected to the threads, a sliding sleeve 4 is slidably sleeved on each of the two rotating shafts 1, multiple groups of supporting frames 3 are movably connected between the two sliding sleeves 4, multiple groups of connecting rods 8 are movably provided between the nuts 7 and the supporting frames 3, a sliding rod 62 is slidably provided in the stabilizing plate 6, and the end of the sliding rod 62 is fixedly connected to the supporting frame 3, a silicone strip 5 is provided outside the supporting frame 3, and a heating belt 9 is provided inside the silicone strip 5.

[0026] Specifically, the utility model rotates the screw rod 2 to make the two nuts 7 move closer to or away from each other. Due to the supporting effect of the connecting rod 8, the supporting skeleton 3 will bend to varying degrees, thereby achieving a change in the flattening arc, thereby adjusting the movement of the protective film and avoiding wrinkles on the surface of the protective film. By arranging a heating belt 9 in the silicone strip 5, when working in an environment with a reduced temperature, the heat generated by the heating belt 9 can be evenly transferred to the protective film through the silicone strip 5, making the protective film soft, making it easier for the flattening roller to flatten the protective film and reducing the probability of wrinkles on the protective film. By arranging a stabilizing plate 6, the stability of the flattening roller is increased, and the stabilizing plate 6 can provide power for the heating belt 9, thereby greatly enhancing the flattening effect of the flattening roller.

[0027] Furthermore, the outer surface of the rotating shaft 1 is provided with edges, and the sliding sleeve 4 is provided with a notch matched with the rotating shaft 1 .

[0028] Specifically, refer to Figure 3 By setting an edge on the rotating shaft 1 and opening a groove matching the edge on the sliding sleeve 4, the sliding sleeve 4 can slide on the rotating shaft 1. When the two nuts 7 approach or move away from each other, the sliding sleeve 4 sliding on the rotating shaft 1 can achieve different degrees of bending of the supporting frame 3, thereby achieving the purpose of changing the curvature of the flattening roller.

[0029] Furthermore, the rotating shaft 1 is a through shaft with a hollow interior, and the screw rod 2 is connected to the rotating shaft 1 via a first bearing 12 .

[0030] Specifically, refer to Figure 3 The outer ring of the first bearing 12 is fixedly connected to the rotating shaft 1 , and the inner ring of the first bearing 12 is fixedly connected to the screw rod 2 .

[0031] Furthermore, a limit block 11 is fixedly sleeved on the rotating shaft 1 , and the limit block 11 limits the movable range of the sliding sleeve 4 .

[0032] Specifically, refer to Figure 1 The limit block 11 is arranged on one side of the rotating shaft 1 close to the stabilizing plate 6 to prevent the sliding sleeve 4 from slipping off the rotating shaft 1 .

[0033] Furthermore, two ends of the support frame 3 are rotatably disposed on a sliding sleeve 4 respectively.

[0034] Specifically, refer to Figure 1 Fourteen groups of bases are arranged on the sliding sleeve 4, one end of the support frame 3 is movably connected to the base through a pin, and the other end of the support frame 3 is movably connected to a base on another sliding sleeve 4 through a pin. There are fourteen groups of support frames 3 arranged in this way.

[0035] Furthermore, one end of the connecting rod 8 is rotatably disposed on the nut 7 , and the other end of the connecting rod 8 is rotatably disposed on the supporting frame 3 .

[0036] Specifically, refer to Figure 1 One end of the connecting rod 8 is movably connected to a base set on the supporting frame 3 through a pin shaft, and the other end of the connecting rod 8 is movably connected to a base set on the nut 7 through a pin shaft. When the supporting frame 3 is rotated, the two nuts 7 approach or move away from each other. Through the support of multiple groups of connecting rods 8, the curvature of the supporting frame 3 changes, thereby changing the curvature of the silicone strip 5. Both ends of the silicone strip 5 are locked on the rotating shaft 1 by screws.

[0037] Furthermore, the stabilizing plate 6 is connected to the screw rod 2 via a second bearing 63 .

[0038] Specifically, referring to the screw rod 2 , the outer ring of the second bearing 63 is fixedly connected to the stabilizing plate 6 , and the inner ring of the second bearing 63 is fixedly connected to the screw rod 2 .

[0039] Furthermore, a slide groove 61 is formed on the stabilizing plate 6 , and one end of a slide rod 62 is slidably disposed in the slide groove 61 .

[0040] Specifically, refer to Figure 2 By providing the slide groove 61, the sliding of the slide rod 62 is made more stable, thereby improving the overall stability of the flattening roller.

[0041] In this utility model, reference is made to Figures 1 to 3 First, limit the rotating shaft 1 and then rotate the screw 2, so that the two nuts 7 move away from or close to each other on the screw 2, so that the connecting rod 8 lifts or pulls back the support frame 3. At this time, the slide bar 62 moves with the movement of the support frame 3, so that the slide bar 62 slides in the slide groove 61, and the silicone strip 5 is propped up under the action of the support frame 3, thereby achieving the change of the curvature while ensuring the stability of the flattening roller, and when the temperature is low, the heating effect of the heating belt 9 makes the silicone strip 5 have a certain temperature, so that the silicone strip 5 is used to evenly transfer the temperature to the protective film, thereby reducing the probability of wrinkles on the protective film.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
