Detailed Embodiments
[0021] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] As Figures 1-4 shown, the present invention provides a protective film leveling mechanism, which is mainly used to strengthen the leveling when transporting the protective film to prevent wrinkles. Its main structure mainly includes a frame 1. Inside the frame 1, a first leveling roller 2, a second leveling roller 3, a third leveling roller 4, a first movable roller 5 and a second movable roller 6 are respectively connected. Among them, the first leveling roller 2 is arranged at one end of the frame 1, the second leveling roller 3 is arranged at the other end of the frame 1, the third leveling roller 4 is arranged between the first leveling roller 2 and the second leveling roller 3, the first movable roller 5 is arranged between the first leveling roller 2 and the third leveling roller 4, and the second movable roller 6 is arranged between the second leveling roller 3 and the third leveling roller 4. In addition, in terms of the horizontal height position, the third leveling roller 4 is arranged above the first leveling roller 2 and the second leveling roller 3, the first movable roller 5 is arranged below the first leveling roller 2, and the second movable roller 6 is arranged below the second leveling roller. At this time, when the protective film is transported, it enters from one end of the first leveling roller 2, passes through the first movable roller 5, the third leveling roller 4 and the second movable roller 6 inside the frame 1, and is output from the second leveling roller 3. Through the treatment of multiple rollers, the protective film can be made flatter, and the internal first movable roller 5 and second movable roller 6 can be selectively used.
[0023] When the protective film is being transported, adjustment modules fixed to the frame 1 are movably connected to both ends of the third leveling roller 4. The adjustment modules can flexibly adjust the tension during the transmission of the protective film according to the tightness of the protective film during the transmission process. The specific structure of the adjustment module mainly includes a movable insertion rod 7 and a base 8 with a cavity inside. One end of the movable insertion rod 7 is inserted into the base 8 and is connected to a block 9 that moves inside the cavity of the base 8. A spring member 10 is arranged inside the cavity of the base 8, and the spring member 10 supports the end of the block 9 away from the movable insertion rod 7. When the protective film is too tight during the transportation process, it will automatically press down the movable insertion rod 7 through the third leveling roller 4, causing the spring member 10 to contract to adjust the tightness. When the protective film is too loose during the transportation process, the spring member 10 will automatically recover without being pressed down, and the spring member 10 will push the movable insertion rod 7 upward to lengthen the path of the protective film transportation to adjust the tightness. The third leveling roller 4 is connected to the end that protrudes after the movable insertion rod 7 is inserted into the base 8, and a hole 11 for inserting the third leveling roller 4 and allowing the third leveling roller 4 to rotate is arranged at the protruding end.
[0024] To prevent the position deviation of the movable rod 7 inserted into the base 8 during telescoping, the outside of the clamping block 9 needs to closely adhere to the inner wall of the cavity of the base 8 and move, ensuring that the clamping block 9 always moves axially within the base 8. Moreover, a spring slot 15 for fixing the spring member 10 is provided at one end of the clamping block 9 connected to the spring member 10.
[0025] In addition, when transporting the protective film, the user can also flexibly adjust the positions of the first movable roller 5 and the second movable roller 6 to change the transport route, which helps to flatten the transported protective film. Both ends of the first movable roller 5 and the second movable roller 6 are inserted into the frame 1 for up and down adjustment and movement, and hollow adjustment holes 12 are provided at the positions where the frame 1 is connected to the first movable roller 5 and the second movable roller 6. The first movable roller 5 and the second movable roller 6 directly rest on the adjustment holes 12 and rotate. To prevent the first movable roller 5 and the second movable roller 6 from falling off during rotation, the first movable roller 5 and the second movable roller 6 are also connected with anti - detachment patches closely attached to the inner side of the frame 1. A number of conducting positions 13 are provided in the adjustment holes 12, and the positions 13 are longitudinally distributed to form different heights. After the first movable roller 5 and the second movable roller 6 move in the adjustment holes 12, they are fixed in the positions 13.
[0026] To facilitate the adjustment of the first movable roller 5 and the second movable roller 6, both ends of the first movable roller 5 and the second movable roller 6 are connected with detachable and coaxially arranged extension rods 14. When the positions of the first movable roller 5 and the second movable roller 6 are adjusted, the extension rods 14 can be detached to prevent collision with the human body.
[0027] Compared with the traditional technology, in this technical solution, when transporting the protective film, by adjusting the positions of the first movable roller 5 and the second movable roller 6, the transport path of the protective film is changed. At the same time, after the third flattening roller 4 is connected to the lower adjustment module, according to the tightness of the protective film during transportation, the adjustment module can automatically press down or rise to buffer the tension of the protective film, achieving a better flattening effect and avoiding wrinkles on the protective film.
[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above - mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non - restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included within the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.
