Description
Technical Field
[0001] The utility model relates to a PET protective film processing device, and more specifically, to a PET protective film leveling device. Background Art
[0002] A PET protective film leveling device is a device specifically used for leveling the protective film during the production process of the PET protective film. Through a specific mechanical structure and working principle, this device aims to solve problems such as wrinkles and unevenness that may occur during the production of the PET protective film, so as to improve the quality and appearance of the protective film.
[0003] During the leveling process of the existing PET protective film, the protective film is placed on a leveling table for horizontal leveling, and then leveled by a leveling roller. During horizontal leveling, the protective film is prone to uneven force, resulting in local unevenness or a wavy shape, reducing the leveling quality.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a PET protective film leveling device. When the PET protective film is vertically arranged, all parts of it are affected by gravity. This acting force is vertically downward and evenly distributed over the entire protective film, without differences due to different directions or positions. Therefore, during the leveling process, the protective film can maintain overall consistency, avoiding deformation caused by uneven local force. When vertically arranged, the tension of the protective film during unfolding or fitting is easier to maintain balance. This stable tension state helps the protective film to be evenly stressed in all directions, preventing local unevenness on the surface of the protective film and improving the leveling quality.
[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: A PET protective film leveling device includes a workbench. A vertical plate is fixedly installed in the middle of the upper end of the workbench. A driving mechanism is arranged at the upper end of the vertical plate. A guiding roller is fixedly installed on the outer surface of the driving mechanism. A chute is opened at the rear side of the right end of the vertical plate. A lead screw is movably connected inside the chute. An adjusting frame is threadedly connected to the outer surface of the lead screw. A leveling roller is movably connected inside the adjusting frame. A feeding roller is arranged at the left end of the vertical plate. A protective film is movably connected to the outer surface of the feeding roller. The protective film is movably connected to the guiding roller. The protective film is located on the right side of the vertical plate and is in contact with the leveling roller. A take-up roller is arranged at the upper right end of the workbench.
[0007] The present utility model is further configured as follows: The driving mechanism includes an arc-shaped plate. There are two arc-shaped plates, and a rotating shaft is movably connected to the opposite surfaces of the two arc-shaped plates. A servo motor is fixedly installed at the front end of the rotating shaft, and the guiding roller is fixedly connected to the outer surface of the rotating shaft.
[0008] The present utility model is further configured as follows: Four support legs are fixedly installed at the lower end of the workbench.
[0009] The present utility model is further configured as follows: The length of the leveling roller is greater than the width of the protective film.
[0010] In summary, the present utility model has the following beneficial effects:
[0011] 1. When the PET protective film is vertically arranged, all parts of it are subjected to the action of gravity. This acting force is vertically downward and is evenly distributed over the entire protective film, without differences due to different directions or positions. Therefore, the protective film can maintain overall consistency during the leveling process, avoiding deformation caused by uneven local stress. When vertically arranged, the tension of the protective film during unfolding or laminating is easier to maintain evenly. This stable tension state helps the protective film to be evenly stressed in all directions, preventing local unevenness on the surface of the protective film and improving the leveling quality.

[0018] The present utility model will be described in detail below with reference to the drawings.
[0019] A PET protective film leveling device, as Figures 1 to 2 shown, includes a workbench 1. A vertical plate 2 is fixedly installed in the middle of the upper end of the workbench 1. A driving mechanism 3 is arranged at the upper end of the vertical plate 2. A guiding roller 4 is fixedly installed on the outer surface of the driving mechanism 3. A sliding groove 5 is formed at the rear side of the right end of the vertical plate 2. A lead screw 6 is movably connected inside the sliding groove 5. An adjusting frame 7 is threadedly connected to the outer surface of the lead screw 6. A leveling roller 8 is movably connected inside the adjusting frame 7. A feeding roller 9 is arranged at the left end of the vertical plate 2. A protective film 10 is movably connected to the outer surface of the feeding roller 9. The length of the leveling roller 8 is greater than the width of the protective film 10. The protective film 10 is movably connected to the guiding roller 4. The protective film 10 is located on the right side of the vertical plate 2 and is in contact with the leveling roller 8. A receiving roller 11 is arranged on the upper right side of the workbench 1. When the lead screw 6 rotates, it drives the adjusting frame 7 to move up and down along the lead screw 6, thereby driving the rotating leveling roller 8 to move up and down to level the protective film 10. At this time, the part of the protective film 10 to be leveled is perpendicular to the workbench 1. When the PET protective film 10 is vertically arranged, all parts of it are affected by gravity. This acting force is vertically downward and is evenly distributed over the entire protective film 10 without any difference due to different directions or positions. Therefore, the protective film 10 can maintain overall consistency during the leveling process, avoiding deformation caused by uneven local stress. When vertically arranged, the tension of the protective film 10 during unfolding or laminating is easier to maintain balanced. This stable tension state helps the protective film 10 to be evenly stressed in all directions, preventing local unevenness on the surface of the protective film 10 and improving the leveling quality.
[0020] Four support legs 12 are fixedly installed at the lower end of the workbench 1. The support legs 12 are provided to play a role in supporting and stabilizing the workbench 1.
[0021] As Figure 2 shown, the driving mechanism 3 includes arc-shaped plates 31. There are two arc-shaped plates 31. A rotating shaft 32 is movably connected to the opposite surfaces of the two arc-shaped plates 31. A servo motor 33 is fixedly installed at the front end of the rotating shaft 32. The guiding roller 4 is fixedly connected to the outer surface of the rotating shaft 32. When the servo motor 33 drives the rotating shaft 32 to rotate, the guiding roller 4 is driven to rotate, and the protective film 10 is conveyed to the contact surface of the flattening roller 8.
[0022] Working principle: When the unwinding roller 9 rotates, the protective film 10 is unwound, and the protective film 10 is placed on the guiding roller 4. When the servo motor 33 drives the rotating shaft 32 to rotate, the guiding roller 4 is driven to rotate, and the protective film 10 is conveyed to the contact surface of the flattening roller 8. When the lead screw 6 rotates, the adjusting frame 7 moves up and down along the lead screw 6, so as to drive the rotating flattening roller 8 to move up and down to flatten the protective film 10. At this time, the part of the protective film 10 to be flattened is perpendicular to the workbench 1. When the PET protective film 10 is vertically arranged, all parts of it are affected by gravity. This acting force is vertically downward and evenly distributed over the entire protective film 10, without any difference due to different directions or positions. Therefore, the protective film 10 can maintain overall consistency during the flattening process, avoiding deformation caused by uneven local stress. When vertically arranged, the tension of the protective film 10 during unfolding or laminating is easier to maintain balanced. This stable tension state helps the protective film 10 to be evenly stressed in all directions, preventing local unevenness on the surface of the protective film 10 and improving the flattening quality.
[0023] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
