Description

Technical Field

[0001] This utility model relates to the field of tension fluctuation suppression technology for release film coating, and in particular to a high-precision release film coating tension fluctuation suppression mechanism. Background Technology

[0002] Release film coating is a process of coating a layer of release agent (usually silicone) onto the surface of a substrate film (such as PET, PE, OPP, etc.). The purpose is to give the film surface a stable and slight release force, making it easy to peel off when in contact with materials such as pressure-sensitive adhesives. During the coating process, the release film is connected to an external unwinding device for coating. During this process, the release film itself will have tension, which will affect the coating effect. Usually, tension fluctuation suppression mechanism is used to suppress the tension of the release film.

[0003] Existing tension suppression mechanisms typically require a detection mechanism to detect tension fluctuations before they can be controlled to suppress tension. However, in actual use, they cannot automatically adjust and suppress tension when changes occur. Therefore, we propose a high-precision release film coating tension fluctuation suppression mechanism. Utility Model Content

A fixed guide mechanism is bolted to the bottom inner side of the mounting frame; A connecting guide mechanism is bolted to both sides of the mounting frame; Fixed support legs are symmetrically arranged on the upper part of the front and rear surfaces of the mounting frame; The self-tensioning mechanism includes a mounting top plate bolted to the top of the mounting frame.

[0014] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0015] Example: As shown in Figure 1-Figure 4 As shown, a high-precision release film coating tension fluctuation suppression mechanism includes: a mounting frame 1, which has threaded mounting holes on both sides, top and inner bottom. Fixed through holes 2 are symmetrically opened on the top of the mounting frame 1; The self-tensioning mechanism 3 is bolted to the inside of the top of the mounting frame 1; The movable guide mechanism 4 is bolted to the output end of the self-tensioning mechanism 3; The fixed guide mechanism 5 is bolted to the bottom inner side of the mounting frame 1; The connecting guide mechanism 6 is bolted to both sides of the mounting frame 1; Fixed support legs 7 are symmetrically arranged on the upper part of the front and rear surfaces of the mounting frame 1; The self-tension adjustment mechanism 3 includes a mounting top plate 31 bolted to the top of the mounting frame 1. A connecting sleeve 32 is fixedly connected to the bottom of the mounting top plate 31. A first spring 35 is fixedly connected to the top of the inner part of the connecting sleeve 32. A force-bearing mounting plate 34 is fixedly connected to the bottom of the first spring 35. A second spring 36 is fixedly connected between the bottom of the force-bearing mounting plate 34 and the bottom of the inner side of the connecting sleeve 32. A movable connecting rod 33 is fixedly connected to the middle of the bottom of the force-bearing mounting plate 34. A through hole adapted to the movable connecting rod 33 is opened at the bottom of the connecting sleeve 32. A connecting base plate 37 is fixedly connected to the bottom of the movable connecting rod 33.

[0016] The working principle of the above technical solution is as follows: During use, the release film can pass through the inner sides of the connecting guide mechanism 6, the moving guide mechanism 4, and the fixed guide mechanism 5, allowing for stable movement. When the tension of the release film fluctuates, it will compress the moving guide mechanism 4, causing the moving guide mechanism 4 to compress the self-tension adjustment mechanism 3. This effectively suppresses the tension fluctuations of the release film, preventing wrinkles and ensuring the coating quality. Operation is convenient. When the tension of the release film fluctuates, it compresses the moving guide mechanism 4, causing it to push against the connecting base 37. This allows the connecting base 37 to push against the movable connecting rod 33 and the force-bearing mounting plate 34, connecting with the connecting sleeve 32. This compresses the first spring 35 and stretches the second spring 36, thus self-adjusting. When the release film no longer compresses the moving guide mechanism 4, the first spring 35 and the second spring 36... It can drive the force-bearing mounting plate 34, the movable connecting rod 33 and the connecting base 37 to reset, so that the moving guide mechanism 4 can move downward to maintain the tension of the release film, making the operation convenient and quick.

[0017] In another embodiment, such as Figure 3 As shown, the outer surface of the connecting sleeve 32 slides and fits against the inner surface of the fixing through hole 2.

[0018] The connecting sleeve 32 can be used stably inside the fixed through hole 2, making operation convenient.

[0019] In another embodiment, such as Figure 2 As shown, the movable guide mechanism 4 includes a movable connecting frame 41 that is bolted to the connecting chassis 37, and a first guide roller 42 is movably connected to the inner side of the movable connecting frame 41 via a connecting shaft.

[0020] The movable connecting frame 41 can be connected to the connecting base 37, and the first guide roller 42 can guide the release film, making operation convenient.

[0021] In another embodiment, such as Figure 2 As shown, the fixed guide mechanism 5 includes a connecting leg 52 that is bolted to the mounting frame 1. One end of the connecting leg 52 is fixedly connected to a connecting base 51. The inner side of the connecting base 51 is movably connected to a second guide roller 53 via a connecting shaft. A connecting reinforcing block 54 is fixedly connected to the lower outer side of the end of the connecting base 51. The bottom of the connecting reinforcing block 54 is in contact with the bottom inner side of the mounting frame 1.

[0022] This allows the release film to move stably over the upper outer surface of the second guide roller 53, enabling the connecting base 51 and the second guide roller 53 to be used stably. At the same time, the connecting reinforcing block 54 can cooperate with the mounting frame 1, enabling the connecting base 51 to be used stably and making operation convenient.

[0023] In another embodiment, such as Figure 4 As shown, the connecting guide mechanism 6 includes a connecting mounting base 61 that is bolted to the outside of the mounting frame 1. A connecting limiting block 62 is fixedly connected to the top of the connecting mounting base 61. A fixed mounting slot 63 is provided on one side of the connecting limiting block 62. A movable connecting block 64 is movably connected to the inside of the fixed mounting slot 63. A third guide roller 65 is fixedly connected to one side of the movable connecting block 64. A connecting block 66 is movably connected to the inside of the fixed mounting slot 63. A fixed connecting frame 67 is fixedly connected to the top of the connecting block 66. The fixed connecting frame 67 and the connecting limiting block 62 are connected and fixed by bolts.

[0024] This facilitates the movement of the third guide roller 65 and the movable connecting block 64, allowing the movable connecting block 64 to be positioned inside the fixed mounting slot 63. The connecting block 66 is then inserted into the fixed mounting slot 63, while the fixed connecting frame 67 is positioned outside the surface of the connecting limit block 62 and is fixedly connected by bolts. This allows the third guide roller 65 to guide the release film, making operation convenient.

[0025] In another embodiment, such as Figure 4 As shown, the outer side of the connecting block 66 is in contact with the inner side of the fixed mounting slot 63, and the bottom end of the connecting block 66 is in contact with the outer side of the movable connecting block 64.

[0026] The connecting block 66 can be stably inserted into the inner side of the fixed mounting slot 63, and the position of the movable connecting block 64 is restricted, so that the movable connecting block 64 and the third guide roller 65 can be used stably and are easy to operate.

[0027] The working principle of this utility model is as follows: First, the entire assembly is installed and fixed. Then, the fixed support 7 is connected and fixed to the coating tank with bolts, allowing the mounting frame 1 to be positioned inside the coating tank. Next, one end of the release film is connected to the upper outer surface of the third guide roller 65, the lower outer surface of the first guide roller 42, and the upper outer surface of the second guide roller 53, with the other end connected to the winding device. This allows the release film to move stably within the tank for coating. During this process, when the first guide roller 42 is subjected to tension fluctuations from the release film, it is squeezed, causing the first guide roller 42 and the movable connecting frame 41 to push against the connecting base 37. This allows the connecting base 37 to push against the movable connecting rod 33 and the force-bearing mounting plate 34, connecting and engaging with the connecting sleeve 32, compressing the first spring 35 and the second spring 36. The release film stretches and adjusts itself. When the release film no longer squeezes the movable connecting frame 41 and the first guide roller 42, the first spring 35 and the second spring 36 can drive the force-bearing mounting plate 34, the movable connecting rod 33 and the connecting base plate 37 to reset, so that the movable connecting frame 41 and the first guide roller 42 can move downward to maintain the tension of the release film. The overall structure is simple and the operation is convenient and quick.

[0028] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
