Description

Technical Field

[0001] The utility model relates to the technical field of film anti-warping, in particular to an asymmetric high-barrier film anti-warping device. Background Art

[0002] An asymmetric high-barrier film, as the name implies, is a high-performance barrier material with a non-uniform structure prepared by a special process. This film material shows asymmetry in structure and usually includes a multi-layer composite structure. The selection and arrangement of each layer of material are carefully designed to achieve the best barrier effect. When the film is cleaned after production, warping will occur. The warped asymmetric barrier film appears uneven in appearance, affecting the aesthetics of the product. At the same time, warping may also cause problems such as air leakage and water seepage in the application of the film sheet, seriously affecting the use performance of the product.

[0003] In the prior art, the reason for warping during cleaning is mainly due to the drying step after cleaning. Generally, the drying work is carried out by a wind drying method during the drying step. The blowing of the wind during drying easily causes the edges of the film to warp due to the blowing of the air flow. Coupled with the subsequent extrusion and conveying of the conveying rollers, it causes bending deformation to form a warping phenomenon. In addition, if hot air drying is used, in addition to the influence of the air flow, it will also be affected by the temperature, resulting in warping of the film, thereby affecting the production quality of the film. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an asymmetric high-barrier film anti-warping device to facilitate solving the technical problems mentioned in the above background art.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] An asymmetric high-barrier film anti-warping device includes a base. On the two long and wide sides of the top of the base, a film unwinding mechanism and a conveying mechanism are respectively arranged. On the two side lengths of the middle part of the top side of the base, positioning plates are fixedly connected. On the side of the positioning plate close to the middle of the base, an installation groove is opened, and a flattening member is arranged in the installation groove;

[0007] The flattening member includes a hollow column and an air pump. The hollow column is fixedly installed in the installation groove. On the side of the hollow column away from the side wall of the installation groove, an air suction port is opened. The air pump is fixedly installed on the side of the positioning plate away from the middle of the base, and the suction end of the air pump is communicated with the hollow column;

[0008] There are two flattening rollers arranged between the two positioning plates. The two flattening rollers are rotatably installed between the two positioning plates, and there is a gap between the two flattening rollers. The output end of the air pump is connected to a circulation member.

[0009] In a preferred example of the present utility model, it can be further configured as follows: on the opposite sides of the two hollow columns are trapezoidal settings, which are used to narrow the width of the air suction port.

[0010] In a preferred example of the present utility model, it can be further configured as follows: the circulation member includes two output pipes. The two output pipes are connected to the output ends of the two air pumps. The ends of the two output pipes extend above the middle of the top side of the base. The ends of the two output pipes are jointly connected to a confluence pipe. The bottom end of the confluence pipe is communicated with a jet block, and jet grooves are opened on both side edges of the jet block.

[0011] In a preferred example of the present utility model, it can be further configured as follows: a positioning rod is fixedly connected between the top sides of the two positioning plates, and the positioning rod is sleeved on the outer peripheral side of the top of the confluence pipe.

[0012] In a preferred example of the present utility model, it can be further configured as follows: the jet block is trapezoidal, and the two jet grooves are respectively located at the bottom sides of the two inclined surfaces of the jet block.

[0013] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0014] 1. When the asymmetric high-barrier film anti-warping device is in use, it can directly suck air through the air pump, and then adsorb the passing film through the hollow columns and the air suction ports provided, so that the edges of the film are pulled, thereby preventing the edges of the film from bridging and causing warping. At the same time, the air pump can also blow and dry the washed film, improving the practicability;

[0015] 2. On the opposite sides of the two hollow columns of the asymmetric high-barrier film anti-warping device are trapezoidal settings, which narrow the width of the air suction port, reducing the adsorption range of the air suction port during air suction, but increasing the adsorption force, preventing the phenomenon that the adsorption force is insufficient when adsorbing the film and causing the film to retract, thus affecting the prevention of warping;

[0016] 3. The output pipes of the asymmetric high-barrier film anti-warping device are connected to the output ends of the air pumps, so that the exhaust end of the air pump can transport the air flow through the output pipes to the confluence pipe, and then the confluence pipe transports the air flow to the jet block, so that the jet block blows the air flow in the direction of the hollow column, and at the same time the air flow blows to the surface side of the film, achieving the effect of air-drying the film;

[0017] 4. The asymmetric high-barrier film anti-warping device is provided with a positioning rod fixedly installed between the top sides of two positioning plates, so that the positioning rod can support the manifold pipe and prevent it from shaking under the influence of air flow, which may cause the unstable air flow ejected by the air jet block and thus affect the effect of air-drying the film.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Referring to Figures 1 - 3 , an asymmetric high-barrier film anti-warping device disclosed by the present invention includes a base 1. Unwinding mechanisms 2 and conveying mechanisms 3 are respectively arranged on the two wide and long sides of the top of the base 1. Two side edges in the middle of the top side of the base 1 are fixedly connected with positioning plates 4. An installation groove 5 is opened on one side of the positioning plate 4 close to the middle of the base 1. A flattening member 6 is arranged in the installation groove 5;

[0026] The flattening member 6 includes a hollow column 7 and an air pump 8. The hollow column 7 is fixedly installed in the installation groove 5. An air suction port 9 is formed on one side of the hollow column 7 away from the side wall of the installation groove 5. The air pump 8 is fixedly installed on one side of the positioning plate 4 away from the middle of the base 1. The suction end of the air pump 8 is communicated with the hollow column 7;

[0027] Two flattening rollers 16 are arranged between the two positioning plates 4. The two flattening rollers 16 are rotatably installed between the two positioning plates 4, and a gap is left between the two flattening rollers 16. The output end of the air pump 8 is connected with a circulation member 10.

[0028] In this embodiment, during use, the cleaned film is input from the unwinding mechanism 2, then passes between the two flattening rollers 16, and then is conveyed to the next processing step through the conveying mechanism 3. When the film is conveyed from the unwinding mechanism 2 to the flattening rollers 16, the film should be kept horizontal and on the same horizontal plane as the air suction port 9; it should be noted that both the unwinding mechanism 2 and the conveying mechanism 3 are prior arts, equivalent to the conveying of conveying rollers;

[0029] Therefore, when the film arrives between the two flattening rollers 16 from the unwinding mechanism 2, the air pump 8 will continuously suck air, and then suck air through the air suction port 9 opened on the void column. Since the film is on the same horizontal plane as the air suction port 9, and when the air around the film is sucked away, due to the air flow, there will be an air pulling force in the direction of the air suction port 9, which will cause the film to be straightened, avoiding the phenomenon that the side of the film warps and is finally pressed and warped, and thus improving the production quality of the film;

[0030] When the film is straightened and conveyed, the output end of the air pump 8 will convey the air flow to the top or bottom side of the film through the circulation member 10, so as to achieve the effect of drying the film by blowing with the wind. The air flow can circulate at the circulation member 10 and the flattening member 6, which can both straighten the film and dry the film.

[0031] In a further preferred embodiment of the present invention, as Figure 2 shown, the opposite sides of the two hollow columns 7 are both trapezoid-shaped, for narrowing the width of the air suction port 9.

[0032] In this embodiment, the opposite sides of the two hollow columns 7 are both trapezoid-shaped, thus narrowing the width of the air suction port 9, making the adsorption range of the air suction port 9 during suction smaller, but increasing the adsorption force, avoiding the phenomenon that the adsorption force is insufficient when adsorbing the film and causing the film to retract, thereby affecting the prevention of the warping phenomenon.

[0033] In a further preferred embodiment of the present invention, as Figure 2As shown, the circulating member 10 includes two output pipes 11. The two output pipes 11 are connected to the output ends of the two air pumps 8. The ends of the two output pipes 11 extend above the middle of the top side of the base 1. A confluence pipe 12 is commonly connected to the ends of the two output pipes 11. The bottom end of the confluence pipe 12 is communicated with a jet block 13. Jet grooves 14 are formed on both side edges of the jet block 13.

[0034] In this embodiment, the provided output pipe 11 is connected to the output end of the provided air pump 8, so that the exhaust end of the air pump 8 can convey the air flow through the output pipe 11 to the confluence pipe 12. The air flow is conveyed to the jet block 13 through the confluence pipe 12, so that the jet block 13 blows the air flow towards the direction of the hollow column 7. At the same time, the air flow will blow towards the surface side of the film, achieving the effect of air-drying the film.

[0035] In addition, a pipeline can be branched at the output end of the air pump 8, and output pipes 11, confluence pipes 12 and jet blocks 13 are also arranged below the film, so as to facilitate the air-drying work on both the upper and lower sides of the film.

[0036] In a further preferred embodiment of the present utility model, as Figure 2 shown, a positioning rod 15 is fixedly connected between the top sides of the two positioning plates 4. The positioning rod 15 is sleeved on the outer peripheral side of the top of the confluence pipe 12.

[0037] In this embodiment, the provided positioning rod 15 is fixedly installed between the top sides of the two positioning plates 4, so that the positioning rod 15 can support the confluence pipe 12 and prevent it from shaking under the influence of the air flow, resulting in unstable air flow ejected by the jet block 13, thereby affecting the air-drying effect on the film.

[0038] In a further preferred embodiment of the present utility model, as Figure 2 shown, the jet block 13 is trapezoidally arranged, and the two jet grooves 14 are respectively located at the bottom sides of the two inclined surfaces of the jet block 13.

[0039] In this embodiment, the two provided jet blocks 13 are trapezoidally arranged, and the soup jet grooves 14 are located at the bottom sides of the corresponding inclined surfaces of the jet block 13, thereby reducing the jet range of the jet grooves 14 and increasing the jet intensity of the jet grooves 14, so as to improve the air-drying efficiency of the jet grooves 14 when jetting air on the film.

[0040] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model should be covered within the protection scope of the present utility model.
