Description

Technical Field

[0001] This invention relates to the field of thin film production technology, and in particular to a thin film tensioning device for thin film production and its usage method. Background Technology

[0002] A thin film is a thin, soft, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, a thin film is a two-dimensional material formed by the deposition of atoms, molecules, or ions on the surface of a substrate. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. Thin films are widely used in the electronics, machinery, and printing industries.

[0003] In film production, many low-quality products are produced. Many factories have introduced film tensioning devices to improve film quality. Currently, most film tensioning methods are extrusion. This method can easily cause wrinkles in the film. Furthermore, during film processing, personnel need to constantly monitor the position of the film to prevent the sides of the film from contacting the device.

[0004] A search revealed that invention patent CN112537682A discloses a film tensioning device for film production, including a base, a first servo motor on one side of the base, a tensioning mechanism at the output end of the first servo motor, an adjustment mechanism inside the tensioning mechanism, and a second servo motor located below the first servo motor on one side. The beneficial effects are as follows: With the adjustable plate, first adjustable roller, smoothing roller, extrusion roller, and fixed roller, and since both sets of first adjustable rollers are located inside the adjustable plate, during use, the first servo motor drives the adjustable plate to rotate, causing the two sets of first adjustable rollers to extrude force on the film in opposite directions, achieving tension. Simultaneously, given the elliptical cross-section of the smoothing roller, and with the extrusion roller and fixed roller fixed, when the smoothing roller tilts upwards, it further tensions the film. The superposition of these two sets makes the adjustment effect of the device more significant. However, although this device can achieve a certain degree of tension, it still uses extrusion for tensioning, which is not ideal. Furthermore, while the device uses adjustable blocks to limit the film and prevent displacement, although this avoids contact between the film and the sides of the device, it still comes into contact with the adjustable blocks, causing displacement and resulting in wrinkles during winding. Therefore, this device still has certain shortcomings. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that most existing technologies use extrusion for tensioning, which is not very effective. Furthermore, while the device uses adjusting blocks to limit the film and prevent it from shifting, it still comes into contact with the adjusting blocks, causing shifting and resulting in wrinkles during winding. Therefore, this invention proposes a film tensioning device for film production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A film tensioning device for film production includes a frame and a guide roller assembly arranged sequentially on the frame. The frame is also provided with a correction component for guiding the film, which is opposite to the guide roller assembly; a tensioning mechanism for tensioning the film, which is located on the frame at the rear end of the correction component; and a finishing component for smoothing the film, which is arranged on the frame and cooperates with the tensioning mechanism. A winding component for winding the film is provided at the end of the frame. The correction assembly includes a first guide roller mounted on the frame via a connecting assembly, a second guide roller connected to the side wall of the frame via a mounting bracket and a connecting assembly, and an adjustment assembly disposed between the first and second guide rollers for adjusting the angle between the first and second guide rollers. The tensioning mechanism includes a tensioning roller movably mounted on the frame and a tensioning assembly disposed between the tensioning roller and the frame for adjusting the tensioning roller.

[0007] As a preferred technical solution of this application, the first guide roller, the second guide roller, the tensioning mechanism, the finishing component, and the winding component are all at different heights. The height of the second guide roller is higher than the height of the first guide roller, the height of the second guide roller and the finishing component are both higher than the height of the tensioning mechanism, and the height of the winding component is lower than the height of the finishing component.

[0008] As a preferred technical solution of this application, the connecting assembly includes a first connecting plate rotatably mounted on the frame via a connecting seat, a second connecting plate with one end rotatably connected to the first connecting plate and the other end connected to the outer wall of the first guide roller via a first bearing, and an elastic element disposed between the first connecting plate and the second connecting plate.

[0009] As a preferred technical solution of this application, the adjustment component includes a third connecting plate rotatably connected to the outer wall of the mounting frame, and a connecting rod with one end rotatably connected to the third connecting plate and the other end connected to the first guide roller and the second guide roller respectively via a second bearing.

[0010] As a preferred technical solution of this application, the tensioning assembly includes a first mounting plate slidably disposed on the inner wall of the frame and a first elastic component disposed between the first mounting plate and the frame, wherein the tensioning roller is connected to the bottom of the first mounting plate through a bearing seat.

[0011] As a preferred technical solution of this application, a screw is connected to the top of the first mounting plate, the end of the screw away from the first mounting plate passes through the frame and extends upward, and an adjusting nut is provided on the outer wall of the screw.

[0012] As a preferred technical solution of this application, the sorting component includes a fixed roller rotatably disposed on the frame and a pressure roller movably disposed on the frame via a second mounting plate, wherein a second elastic component is disposed between the top of the second mounting plate and the frame.

[0013] As a preferred technical solution of this application, the first elastic component and the second elastic component have the same structure, both including a guide rod that passes through the frame, a spring sleeved on the outer wall of the guide rod, and a limiting block disposed at the top of the guide rod.

[0014] As a preferred technical solution of this application, the end of the tensioning roller is connected to an ion fan via a connecting hose, and an air outlet is provided on the tensioning roller.

[0015] A method for using a film tensioning device for film production specifically includes the following steps: S1: The film to be wound is passed through the guide roller group, tensioning mechanism, and sorting component in sequence and wound onto the winding component and the winding roller on the winding component. The production film is wound up by the drive motor. S2: Through the tensioning mechanism, during the film winding process, under the action of the elastic force of the first elastic component and the weight of the tensioning roller itself, the tensioning roller is positioned below the correction component, and its height is lower than the height of the correction component and the straightening component. Therefore, the film will be in a U-shape, which can effectively keep the film passing through the tensioning roller in a taut state. Furthermore, when the film is relatively loose, and the spring force and the weight of the tensioning roller itself are insufficient to keep the film in a taut state, the position of the first mounting plate can be moved down by rotating the adjusting nut to ensure that the film is in a taut state. At the same time, through the spring, when the film is in an overly taut state, the spring can provide a good cushioning effect to prevent it from tearing and improve the performance of the device. S3: When the film being wound shifts, the film on the feed rollers will shift sequentially. One end of the first or second guide roller will be subjected to greater pressure. Both ends of the first and second guide rollers are connected to the frame via connecting components. Therefore, when one end is subjected to different pressures, it will shift downwards relative to the other end. When one end of the first guide roller shifts, the connecting rod will drive the third connecting plate connected to it to rotate. In turn, the connecting rod connected to the other end of the third connecting plate will drive the second guide roller to shift upwards, thereby adjusting the angle of the second guide roller and adjusting the force on the conveyed film. This causes the conveyed film to shift towards the other end of the second guide roller and eventually reach a balanced state, effectively correcting its deviation. After the second guide roller is in a balanced state, the connecting rod and the third connecting plate will drive the first guide roller to gradually reach a balanced state, thus effectively ensuring that the conveyed film is in a stable and taut state, avoiding deviation and slack, which would cause wrinkles in the wound film and affect its quality. S4: The film passing through the tensioning mechanism passes through the sorting component. Through the set second elastic component, the pressure roller can always be in contact with the fixed roller under the drive of the spring, so as to perform a good smoothing and clamping operation on the film, avoid its deviation, and also avoid the occurrence of wrinkles, thus improving the film winding effect. S5: By starting the ion fan and blowing air onto the film surface through the connected hose and air outlet, static electricity on the film surface can be effectively removed, reducing the adsorption of dust and other impurities on the surface and improving film quality.

[0016] Compared with the prior art, the present invention provides a film tensioning device for film production, which has the following advantages: 1. This film tensioning device for film production, through its tensioning mechanism, can effectively ensure that the wound film is in a taut state, avoiding insufficient film tension that could lead to wrinkles during film winding and affect film production quality. At the same time, it can also buffer the film during film transport to prevent tearing. 2. The film tensioning device for film production, through the set correction component, can effectively correct the film that has deviated during the winding process, so as to stabilize it in a balanced conveying state and avoid the deviation from affecting the film quality. 3. This film tensioning device for film production, through its set-up sorting components, can effectively smooth and tension the wound film, further preventing deviations and improving film production quality. 4. The film tensioning device for film production, through the ion fan, connecting hose and air outlet, can effectively remove static electricity from the film surface, reduce the adsorption of dust and other impurities on the surface, and improve film quality.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 A film tensioning device for film production includes a frame 100 and a guide roller group 101 arranged sequentially on the frame 100. The frame 100 is also provided with a correction component 200 that is opposite to the guide roller group 101 and is used to guide the film, a tensioning mechanism 300 that is arranged on the frame 100 at the rear end of the correction component 200 for tensioning the film, and a finishing component 400 that is arranged on the frame 100 and cooperates with the tensioning mechanism 300 to smooth the film. The finishing component 400 can smooth the wound film to avoid leaving air bubbles or wrinkles on the film. A winding component 500 for winding the film is provided at the end of the frame 100. The correction component 200 includes a first guide roller 201 mounted on the frame 100 via a connecting component 600, a second guide roller 202 connected to the side wall of the frame 100 via a mounting frame 207 and the connecting component 600, and an adjustment component 203 disposed between the first guide roller 201 and the second guide roller 202 for adjusting the angle between the first guide roller 201 and the second guide roller 202. It can play a good correction role for the film during winding, and avoid deviation that would affect the winding quality. The tensioning mechanism 300 includes a tensioning roller 301 movably mounted on the frame 100 and a tensioning component 302 disposed between the tensioning roller 301 and the frame 100 for adjusting the tensioning roller 301. The tensioning mechanism 300 can effectively ensure that the wound film is in a taut state, avoiding insufficient film tension that could cause wrinkles during film winding and affect film production quality. At the same time, it can also buffer the film during film transport to prevent tearing.

[0021] Reference Figure 1-4The first guide roller 201, the second guide roller 202, the tensioning mechanism 300, the finishing component 400, and the winding component 500 are all at different heights. The second guide roller 202 is higher than the first guide roller 201. The heights of the second guide roller 202 and the finishing component 400 are both higher than the height of the tensioning mechanism 300. The height of the winding component 500 is lower than the height of the finishing component 400. This creates a certain height difference between the rollers, which can effectively prevent the film from becoming loose during winding, thus avoiding wrinkles and other issues.

[0022] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The connecting assembly 600 includes a first connecting plate 602 rotatably mounted on the frame 100 via a connecting seat 601, a second connecting plate 604 rotatably connected at one end to the first connecting plate 602 and at the other end connected to the outer wall of the first guide roller 201 via a first bearing 603, and an elastic element 605 disposed between the first connecting plate 602 and the second connecting plate 604. The first connecting plate 602 and the second connecting plate 604, with the elastic element 605 connecting them, ensure that the first guide roller 201 or the second guide roller 202 can move when subjected to pressure caused by film deviation. The adjusting assembly 203, in conjunction with the assembly, can effectively achieve a good correction effect and ensure the stability of film conveying.

[0023] Reference Figure 1-4 The adjustment component 203 includes a third connecting plate 204 rotatably connected to the outer wall of the mounting frame 207, and a connecting rod 206, one end of which is rotatably connected to the third connecting plate 204 and the other end of which is connected to the first guide roller 201 and the second guide roller 202 respectively via a second bearing 205. When the first guide roller 201 or the second guide roller 202 is subjected to film pressure, a certain displacement will occur, which will drive the third connecting plate 204 to rotate through the connecting rod 206. The other connecting rod 206 will drive the corresponding first guide roller 201 or the second guide roller 202 to adjust the angle accordingly, thereby driving the film back to the middle of the roller for smooth conveying, avoiding deviation and improving the film production quality.

[0024] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 The tensioning assembly 302 includes a first mounting plate 303 slidably disposed on the inner wall of the frame 100 and a first elastic assembly 304 disposed between the first mounting plate 303 and the frame 100, wherein the tensioning roller 301 is connected to the bottom of the first mounting plate 303 via a bearing seat 305.

[0025] A screw 306 is connected to the top of the first mounting plate 303. The end of the screw 306 away from the first mounting plate 303 passes through the frame 100 and extends upward. An adjusting nut 307 is provided on the outer wall of the screw 306. Through the tensioning component 302, the wound film can be effectively kept in a taut state, avoiding insufficient film tension that could cause wrinkles during film winding and affect film production quality. When the elasticity of the spring 406 and the weight of the tensioning roller 301 are insufficient to keep the film taut, the position of the first mounting plate 303 can be moved downward by rotating the adjusting nut 307 to ensure that the film is taut. At the same time, the spring 406 can provide a good cushioning effect when the film is too taut, preventing it from tearing and improving the efficiency of the device.

[0026] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 The sorting component 400 includes a fixed roller 401 rotatably mounted on the frame 100 and a pressure roller 403 movably mounted on the frame 100 via a second mounting plate 402. A second elastic component 404 is disposed between the top of the second mounting plate 402 and the frame 100.

[0027] Reference Figure 2 , Figure 4 and Figure 6 The first elastic component 304 and the second elastic component 404 have the same structure, both including a guide rod 405 that penetrates the frame 100, a spring 406 sleeved on the outer wall of the guide rod 405, and a limiting block 407 set on the top of the guide rod 405. Through the set sorting component 400, the wound film can be effectively smoothed and tensioned, further avoiding deviation and improving the film production quality.

[0028] Reference Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 An ion fan 309 is connected to the end of the tension roller 301 via a connecting hose 308. An air outlet 310 is provided on the tension roller 301. Through the ion fan 309, the connecting hose 308 and the air outlet 310, static electricity on the film surface can be effectively removed, reducing the adsorption of dust and other impurities on the surface and improving the film quality.

[0029] Specifically, the film tensioning device used in this film production operates as follows: The film to be wound is passed sequentially through the guide roller group 101, the correction component 200, the tensioning mechanism 300, and the sorting component 400 and wound onto the winding component 500. The winding roller 501 on the winding component 500 is detachably connected to the frame 100 and achieves the winding effect of the produced film through the drive motor. During the film winding process, the tensioning mechanism 300, under the action of the elastic force of the first elastic component 304 and the weight of the tensioning roller 301, keeps the tensioning roller 301 below the correction component 200. Its height is lower than both the correction component 200 and the straightening component 400, resulting in a U-shaped film. This effectively keeps the film taut as it passes through the tensioning roller 301. Furthermore, when the film is relatively loose, and the elastic force of the spring 406 and the weight of the tensioning roller 301 are insufficient to keep the film taut, the position of the first mounting plate 303 can be lowered by rotating the adjusting nut 307 to ensure the film remains taut. Simultaneously, the spring 406 provides good cushioning when the film is overly taut, preventing tearing and improving the device's performance. When the wound film deviates, the film on the feed rollers will all deviate sequentially. One end of the first guide roller 201 or the second guide roller 202 will be subjected to greater pressure. Since both ends of the first guide roller 201 and the second guide roller 202 are connected to the frame 100 via connecting components 600, when one end is subjected to different pressures, it will deviate downwards relative to the other end. When one end of the first guide roller 201 deviates, the connecting rod 206 will drive the connected third connecting plate 204 to rotate, and then the connecting rod 206 connected to the other end of the third connecting plate 204 will... This will cause the second guide roller 202 to shift upward, thereby adjusting the angle of the second guide roller 202 and adjusting the force on the conveyed film. This causes the conveyed film to shift towards the other end of the second guide roller 202 and eventually reach a balanced state, effectively correcting its deviation. After the second guide roller 202 is in a balanced state, it will then drive the first guide roller 201 to gradually reach a balanced state through the connecting rod 206 and the third connecting plate 204. This effectively ensures that the conveyed film is in a stable and taut state, avoiding deviation and slack, which would cause wrinkles in the wound film and affect its quality. The film passing through the tensioning mechanism 300 passes through the sorting component 400. Through the second elastic component 404, the pressure roller 403 is always in contact with the fixed roller 401 under the drive of the spring 406, which can effectively smooth and clamp the film, prevent it from shifting, avoid wrinkles, and improve the film winding effect. By activating the ion fan 309 and blowing air onto the film surface through the connected hose 308 and air outlet 310, static electricity on the film surface can be effectively removed, reducing the adsorption of dust and other impurities on the surface and improving film quality.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method of using a film tensioning device for film production, characterized in that, Specifically, the following steps are included: S1: The film to be wound is passed through the guide roller group (101), the correction component (200), the tensioning mechanism (300), and the sorting component (400) in sequence and wound onto the winding component (500). The winding roller (501) on the winding component (500) is detachably connected to the frame (100) and the winding effect of the produced film is achieved by the drive motor. S2: Through the tensioning mechanism (300), during the film winding process, under the action of the elastic force of the first elastic component (304) and the gravity of the tensioning roller (301), the tensioning roller (301) is positioned below the correction component (200), and its height is lower than the height of the correction component (200) and the straightening component (400). Therefore, the film will be in a U-shape, which can effectively keep the film passing through the tensioning roller (301) in a taut state. Furthermore, when the film is relatively loose, if the elastic force of the spring (406) and the gravity of the tensioning roller (301) are insufficient to keep the film in a taut state, the position of the first mounting plate (303) can be moved down by rotating the adjusting nut (307) to ensure that the film is in a taut state. At the same time, through the spring (406), when the film is in an overly taut state, the spring (406) can provide a good buffering effect to prevent it from tearing and improve the device's performance. S3: When the wound film deviates, the film on the feed rollers will deviate sequentially. One end of the first guide roller (201) or the second guide roller (202) will be subjected to greater pressure. Since both ends of the first guide roller (201) and the second guide roller (202) are connected to the frame (100) through connecting components (600), when one end is subjected to different pressures, it will deviate downward relative to the other end. When one end of the first guide roller (201) deviates, the connecting rod (206) will drive the third connecting plate (204) connected to it to rotate, and then the connecting rod connected to the other end of the third connecting plate (204) will rotate. (206) will drive the second guide roller (202) to shift upward, thereby adjusting the angle of the second guide roller (202) and adjusting the force on the conveyed film, so that the conveyed film shifts to the other end of the second guide roller (202) and finally reaches a balanced state, effectively correcting its deviation. After the deviation is corrected, the second guide roller (202) is in a balanced state, and then through the connecting rod (206) and the third connecting plate (204), the first guide roller (201) is gradually brought to a balanced state, thereby effectively ensuring that the conveyed film is in a stable and taut state, avoiding deviation and slack, which would cause wrinkles in the wound film and affect its quality. S4: The film passing through the tensioning mechanism (300) passes through the sorting component (400), and through the set second elastic component (404), the pressure roller (403) is always in contact with the fixed roller (401) under the drive of the spring (406), which can effectively smooth and clamp the film, prevent it from shifting, and also prevent wrinkles from occurring, thus improving the film winding effect; S5: By starting the ion blower (309) and blowing air onto the film surface through the connecting hose (308) and the air outlet (310), static electricity on the film surface can be effectively removed, dust and other impurities adsorbed on the surface can be reduced, and the film quality can be improved.
