The edge-correcting frame has a rotating component at one end along the film transport direction and a first edge-correcting sliding component at the other end. An edge-correcting roller is mounted on the edge-correcting frame. The edge-correcting base has an edge-correcting drive component for driving the edge-correcting frame to rotate.

Description

Technical Field

[0001] This utility model relates to the field of film winding technology, specifically to an edge-correcting device for a fully automatic winding machine. Background Technology

[0002] When a winding machine winds up film, the film is prone to deviation during continuous winding, which can lead to uneven winding or even scrapping of the film. Therefore, it is necessary to install an edge correction device on the winding machine to correct the deviation of the film.

[0003] Chinese utility model patent publication number "CN212581121U" discloses a web-correcting device for a heavy-duty film winding machine. It includes a rectangular winding machine platform, a rectangular web-correcting frame mounted on the platform, and a cylindrical web-correcting roller mounted on the frame. Spherical rolling elements are located at both ends of the web-correcting frame near the winding machine platform. The end of the web-correcting frame away from the rolling elements is rotatably mounted via a cylindrical rotating element. A drive cylinder is mounted on the web-correcting frame to drive it to swing around the rotating element. Web-detecting devices are located on both sides of the web-correcting roller on the winding machine platform; in this embodiment, the web-detecting devices are preferably infrared web-detectors. Operating the drive cylinder causes the web-correcting frame to rotate around the rotating element, and the web-correcting frame rolls left and right on the rolling elements, thereby causing the web-correcting roller to swing left and right, achieving the effect of correcting the deviation of the heavy-duty film.

[0004] However, the aforementioned correction device still has the following drawbacks:

[0005] First, the edge-correcting frame is only equipped with one correction roller. When the film passes through the correction device, the correction roller can only support the film and cannot prevent the film from deflecting. The drive cylinder can only be activated to rotate the correction frame and correct the film when the film deflects, which is quite inconvenient.

[0006] Second, in conjunction with the contents of the publicly available documents and the appendices to the documents... Figure 1 Included with instruction manual Figure 2 It can be seen that the rotating part and the rolling part are respectively set at both ends of the correction frame along the film conveying direction. One end of the correction frame is rotatably connected to the machine base through the rotating part, and the other end is slidably connected to the machine base through the rolling part. It can be seen that the correction frame and the machine base are only supported by three points. When correcting the film, the side of the correction frame near the rotating part is prone to shaking or vibration, causing the film to shift again during the correction process. The edge correction stability and reliability are poor.

[0007] Third, the correction device uses a cylinder to drive the correction frame to rotate around the rotating part. However, the cylinder needs to be filled with air pressure, and the correction adjustment response speed is slow. It cannot quickly correct the offset film. In addition, the correction frame is only equipped with one correction roller. When the film passes through the correction roller, it is easy to come into contact with the correction frame, causing the film to be damaged and resulting in the film being scrapped.

[0008] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0009] The purpose of this invention is to provide an edge-correcting device for a fully automatic winding machine that can maintain the film tension and provide stable and rapid edge correction, so as to solve the above-mentioned problems existing in the prior art.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an edge-correcting device for a fully automatic winding machine, comprising an edge-correcting seat and an edge-correcting frame disposed on the edge-correcting seat, wherein the edge-correcting frame is provided with a rotating component at one end along the film conveying direction and a first edge-correcting sliding component at the other end, an edge-correcting roller shaft is provided on the edge-correcting frame, and the edge-correcting seat is provided with an edge-correcting driving component for driving the edge-correcting frame to rotate, characterized in that: an arc-shaped flattening roller shaft is also provided on the edge-correcting frame, the flattening roller shaft is rotatably connected to the edge-correcting frame, and the flattening roller shaft and the edge-correcting roller shaft are linked to cause the film to be laid flat on the edge-correcting device.

[0011] By adopting the above technical solution: the flattening roller has an arc shape in the middle, which flattens and spreads the film when it passes through the edge straightening device, reducing the probability of deflection during film winding. At the same time, when the film deflects, the edge straightening drive pushes the edge straightening frame to rotate around the rotating component, the first edge straightening sliding component guides the edge straightening frame, the edge straightening roller re-tensions the film, and the flattening roller flattens and spreads the film, realizing rapid edge straightening of the deflected film and improving the yield during winding.

[0012] The edge-correcting device of the aforementioned fully automatic winding machine can be further configured as follows: the flattening roller shaft includes a flattening rod and a flattening sleeve. The flattening sleeve is in the shape of an arc. Roller sleeve seats are provided at both ends of the flattening sleeve. Flattening bearings are provided inside the roller sleeve seats. The flattening sleeve rotates circumferentially around the central axis of the flattening rod through the flattening bearings. The flattening rod is linked to a flattening limiting component, which is used to limit the axial movement of the roller sleeve seats.

[0013] By adopting the above technical solution: the flattening sleeve is arc-shaped, and the flattening sleeve rotates with the flattening rod through the flattening bearing on the roller sleeve seat, so that the flattening sleeve can rotate flexibly on the flattening rod, thereby flattening the film from the middle to both sides by the flattening sleeve. In addition, the flattening limiting component axially limits the roller sleeve seat, ensuring that the flattening sleeve is stable along the axis during rotation, thereby ensuring that the flattening roller shaft stably flattens the film, and further improving the stability and reliability of the edge straightening device.

[0014] The edge-correcting device of the above-mentioned fully automatic winding machine can be further configured as follows: the edge-correcting frame is provided with flattening brackets on both sides along the film transfer direction, one end of the flattening bracket is fixedly connected to the edge-correcting frame and the other end is provided with a connecting sleeve, the connecting sleeve is provided with a connecting hole, the connecting sleeve is connected to the connecting hole and has a locking hole, the end of the flattening rod is rotatably connected to the connecting sleeve, and a locking element for limiting the rotation of the flattening rod is provided in the locking hole.

[0015] By adopting the above technical solution: the flattening rod is installed on the flattening bracket through the connecting sleeve, and the flattening rod can rotate in the connecting hole to adjust the position of the arc protrusion of the flattening sleeve, thereby adjusting the flattening arc of the film. It can be applied to a variety of different films, improving the applicability of the edge straightening device. After the angle is adjusted, the flattening rod can be fixed in the connecting hole through the locking hole to maintain the flattening arc of the flattening roller and improve the stability of the film flattening.

[0016] The edge-correcting device of the aforementioned fully automatic winding machine can be further configured as follows: the first edge-correcting sliding component includes a first edge-correcting block disposed on both sides of the edge-correcting seat, the first edge-correcting block being inclined to the edge-correcting seat, the first edge-correcting block being laterally provided with a first edge-correcting groove, the edge-correcting frame being provided with a first edge-correcting support plate, one end of the first edge-correcting support plate being fixedly connected to the edge-correcting frame, and the other end being provided with a first edge-correcting wheel, the first edge-correcting wheel being slidably engaged with the first edge-correcting groove, and the edge-correcting drive unit being rotated to drive the first edge-correcting wheel to reciprocate within the first edge-correcting groove.

[0017] By adopting the above technical solution: the first edge-correcting block and the edge-correcting seat are set at an inclination, so that the first edge-correcting groove has a certain guiding angle. When the correction drive is running, it can drive the first edge-correcting wheel to move back and forth stably in the first edge-correcting groove, thereby realizing the precise movement and positioning of the edge-correcting frame, effectively guiding the transmission direction of the film, ensuring the accuracy and reliability of the edge-correcting process, further improving the correction effect of the edge-correcting device on film deflection, and ensuring the winding quality.

[0018] The edge-correcting device of the aforementioned fully automatic winding machine can be further configured as follows: a second edge-correcting sliding component is provided at one end of the edge-correcting frame near the rotating part. The second edge-correcting sliding component includes a second edge-correcting block disposed on both sides of the edge-correcting seat. The second edge-correcting block is inclined to the edge-correcting seat and inclined to the first edge-correcting block. A second edge-correcting groove is opened laterally on the second edge-correcting block. The edge-correcting frame is provided with a second edge-correcting support plate. One end of the second edge-correcting support plate is fixedly connected to the edge-correcting frame, and the other end is provided with a second edge-correcting wheel. The second edge-correcting wheel slides in cooperation with the second edge-correcting groove. The edge-correcting drive unit drives the second edge-correcting wheel to reciprocate within the second edge-correcting groove.

[0019] By adopting the above technical solution: since the first edge-correcting sliding component is located at the end of the edge-correcting frame relative to the rotating part, the rotation radius of the first edge-correcting sliding component is relatively large, while the second edge-correcting sliding component is located at the end closer to the rotating part, and the sliding radius of the second edge-correcting sliding component is relatively small. Therefore, the tilt angle between the first edge-correcting block and the edge-correcting seat is larger than the tilt angle between the second edge-correcting sliding component and the edge-correcting seat, ensuring that the edge-correcting frame can have a larger edge-correcting range. At the same time, the first and second edge-correcting blocks are totaled in four parts and located at the four corners of the edge-correcting seat, which can provide stable support for the edge-correcting frame and improve the stability of the edge-correcting frame during the edge-correcting rotation process.

[0020] The edge-correcting device of the aforementioned fully automatic winding machine can be further configured as follows: the edge-correcting drive is a servo electric cylinder, the edge-correcting seat is provided with a hinge shaft, the edge-correcting drive is provided with a hinge ear, the edge-correcting drive is hinged to the hinge shaft through the hinge ear, the output end of the edge-correcting drive is provided with a connector, the edge-correcting frame is provided with a connecting shaft, the connecting shaft is hinged to the connector, and when the edge-correcting drive is running, it can rotate relative to the edge-correcting seat and push the edge-correcting frame to rotate around the rotating component.

[0021] By adopting the above technical solution: the servo electric cylinder, as the edge-correcting drive component, has high control precision and response speed, thereby achieving rapid edge correction of the film. At the same time, the edge-correcting drive component is hinged to the hinge shaft on the edge-correcting seat through the hinge ear, which can adapt to the swinging needs of the edge-correcting frame and improve the rotation range of the edge-correcting frame. Meanwhile, the output end of the edge-correcting drive component is hinged to the connecting shaft on the edge-correcting frame, so that it can rotate relative to the edge-correcting frame when pushing the edge-correcting frame to rotate around the rotating component, further improving the rotation range of the edge-correcting frame, thereby improving the edge-correcting range of the edge-correcting device.

[0022] The edge-correcting device of the aforementioned fully automatic winding machine can be further configured as follows: the rotating component includes a rotating shaft on the edge-correcting frame and a bearing with a seat on the edge-correcting seat. The rotating shaft and the bearing with a seat are rotatably coupled. The bearing with a seat has a first mounting hole. The edge-correcting seat has a mounting plate. The mounting plate has a second mounting hole corresponding to the mounting hole. The bearing with a seat is fixedly connected to the mounting plate by connecting bolts provided in the first mounting hole and the second mounting hole. The mounting plate has a rotating hole in the middle, and the end of the rotating shaft can pass through the rotating hole.

[0023] By adopting the above technical solution: the seated bearing is installed on the mounting plate of the edge straightening seat, and the rotating shaft and the seated bearing are rotatably engaged, making the rotating part stable and flexible in rotation. At the same time, the seated bearing is fixedly connected to the mounting plate through the connecting bolt, which enhances the stability of the structure and improves the convenience of maintenance. In addition, when the edge straightening frame rotates around the rotating part, the rotating part can withstand a certain radial and axial load, ensuring the smooth rotation of the edge straightening frame, thereby ensuring the stability and reliability of the edge straightening device when correcting film deflection. Furthermore, when the rotating shaft and the seated bearing are rotatably engaged, the end of the rotating shaft can pass through the rotating hole without contacting the mounting plate or the edge straightening seat, reducing the resistance when the rotating shaft rotates and improving the stability of the edge straightening frame rotation.

[0024] The edge-correcting device of the aforementioned fully automatic winding machine can be further configured as follows: the edge-correcting roller shaft includes an edge-correcting rod and an edge-correcting cylinder sleeved on the edge-correcting rod. The edge-correcting cylinder is provided with edge-correcting bearings at both ends, and the edge-correcting bearings pass through the edge-correcting rod. The edge-correcting rod is provided with edge-correcting limiting parts at both ends to limit the axial movement of the edge-correcting cylinder. The edge-correcting frame is provided with an edge-correcting support plate. One end of the edge-correcting support plate is fixedly connected to the edge-correcting frame, and the other end is provided with an adjustment groove. A fixing bolt passes through the adjustment groove, and the fixing bolt is threadedly connected to the end of the edge-correcting rod.

[0025] By adopting the above technical solution: the alignment cylinder is sleeved on the alignment rod via an alignment bearing, allowing for flexible rotation. This ensures smooth and unobstructed passage of the film through the alignment roller shaft during transport, preventing damage or deflection caused by excessive friction. The alignment limiting component restricts the axial movement of the alignment cylinder, ensuring it maintains a stable axial position during rotation, thus providing uniform and stable tension and alignment of the film. The adjustment groove and fixing bolt on the alignment support plate allow for fine-tuning of the alignment rod's installation position as needed, thereby adjusting the tension of the film on the alignment roller shaft and further improving the applicability of the alignment device.

[0026] The beneficial effects of this utility model are as follows: the correction mechanism flattens the passing film by setting flattening rollers, which can effectively reduce the probability of friction and deflection. Even if the film deviates, the edge correction drive precisely controls the edge correction frame to rotate around the rotating part, and re-tensions the film. At the same time, during the edge correction process, the first edge correction sliding component and the second edge correction sliding component can provide support for the rotation of the edge correction frame, improving the stability of the edge correction process. Compared with the prior art, which only sets a set of edge correction rollers on the edge correction frame and sets the rolling part on only one end, the edge correction device of this application is more accurate and faster in correcting the edge of the film, which can effectively reduce the probability of film deflection. At the same time, the edge correction frame is more stable when rotating and will not vibrate, making the edge correction of the film more stable and efficient.

Detailed Implementation

[0037] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] like Figures 1 to 8 The edge-correcting device of a fully automatic winding machine shown includes an edge-correcting seat 1 and an edge-correcting frame 2 disposed on the edge-correcting seat 1. The edge-correcting frame 2 has a rotating component 3 at one end along the film conveying direction and a first edge-correcting sliding component 4 at the other end. The edge-correcting frame 2 is provided with a correction roller 5. The edge-correcting seat 1 is provided with an edge-correcting drive component 6 for driving the edge-correcting frame 2 to rotate. The edge-correcting frame 2 is also provided with an arc-shaped flattening roller 7. The flattening roller 7 is rotatably connected to the edge-correcting frame 2. The flattening roller 7 and the correction roller 5 work together to make the film lay flat on the edge-correcting device. The flattening roller 7 has an arc shape in the middle. When the film passes through the edge straightening device, it flattens and spreads the film, reducing the probability of film deflection. At the same time, when the film deflects, the edge straightening drive 6 pushes the edge straightening frame 2 to rotate around the rotating component 3. The first edge straightening sliding component 4 guides the edge straightening frame 2, the edge straightening roller 5 re-tensions the film, and the flattening roller 7 flattens and spreads the film, realizing rapid edge straightening of the deflected film and improving the yield during winding.

[0039] like Figures 2 to 4The flattening roller 7 shown includes a flattening rod 71 and a flattening sleeve 72. The flattening sleeve 72 is arc-shaped, with roller sleeve seats 73 at both ends. Flattening bearings 74 are installed inside the roller sleeve seats 73. The flattening sleeve 72 rotates circumferentially around the central axis of the flattening rod 71 through the flattening bearings 74. The flattening rod 71 is linked to a flattening limiting component 75, which is used to axially limit the roller sleeve seats 73. The flattening sleeve 72 is arc-shaped, and the flattening sleeve 72 rotates with the flattening rod 71 through the flattening bearings 74 on the roller sleeve seats 73, allowing the flattening sleeve 72 to rotate flexibly on the flattening rod 71. This allows the film to be flattened from the middle to both sides by the flattening sleeve, and the flattening limiting component 75 axially limits the roller sleeve seats 73, ensuring that the position of the flattening sleeve 72 along the axis is stable during rotation. This ensures that the flattening roller 7 stably flattens the film, further improving the stability and reliability of the edge straightening device.

[0040] like Figure 1 , Figure 2 The edge-correcting frame 2 shown has flattening brackets 76 on both sides along the film transport direction. One end of the flattening bracket 76 is fixedly connected to the edge-correcting frame 2, and the other end is provided with a connecting sleeve 77. The connecting sleeve 77 has a connecting hole 771, and the connecting sleeve 77 has a locking hole 772 connected to the connecting hole 771. The end of the flattening rod 71 is rotatably connected to the connecting sleeve 77. The locking hole 772 is provided with a locking element for limiting the rotation of the flattening rod 71. The flattening rod 71 is installed on the flattening bracket 76 through the connecting sleeve 77. At the same time, the flattening rod 71 can rotate in the connecting hole 771, which can adjust the position of the arc protrusion of the flattening sleeve 72, thereby adjusting the flattening arc of the film. It can be used for various different films, improving the applicability of the edge-correcting device. After the angle is adjusted, the flattening rod 71 can be fixed in the connecting hole 771 through the locking hole 772 to maintain the flattening arc of the flattening roller 7 and improve the stability of the film flattening.

[0041] like Figure 2The edge-correcting drive unit 6 shown is a servo electric cylinder 61. The edge-correcting base 1 is provided with a hinge shaft 11. The edge-correcting drive unit 6 is provided with a hinge ear 62. The edge-correcting drive unit 6 is hinged to the hinge shaft 11 through the hinge ear 62. The output end of the edge-correcting drive unit 6 is provided with a connector 63. The edge-correcting frame 2 is provided with a connecting shaft 21. The connecting shaft 21 is hinged to the connector 63. When the edge-correcting drive unit 6 is running, it can rotate relative to the edge-correcting base 1 and push the edge-correcting frame 2 to rotate around the rotating member 3. The servo electric cylinder 61, as the edge-correcting drive component 6, has high control precision and response speed, thereby achieving rapid edge correction of the film. At the same time, the edge-correcting drive component 6 is hinged to the hinge shaft 11 on the edge-correcting seat 1 through the hinge ear 62, which can adapt to the swinging needs of the edge-correcting frame 2 and improve the rotation range of the edge-correcting frame 2. Meanwhile, the output end of the edge-correcting drive component 6 is hinged to the connecting shaft 21 on the edge-correcting frame 2, so that it can rotate relative to the edge-correcting frame 2 when pushing the edge-correcting frame 2 to rotate around the rotating component 3, further improving the rotation range of the edge-correcting frame 2, thereby improving the edge-correcting range of the edge-correcting device.

[0042] like Figure 5 The shown straightening roller 5 includes a straightening rod 51 and a straightening cylinder 52 sleeved on the straightening rod 51. Straightening bearings 53 are provided at both ends of the straightening cylinder 52, and the bearings 53 pass through the straightening rod 51. Straightening limiters 54 for limiting the axial movement of the straightening cylinder 52 are provided at both ends of the straightening rod 51. The straightening frame 2 is provided with a straightening support plate 55. One end of the support plate 55 is fixedly connected to the frame 2, and the other end has an adjustment groove 56. A fixing bolt 57 passes through the adjustment groove 56 and is threadedly connected to the end of the straightening rod 51. The straightening cylinder 52 is sleeved on the straightening rod 51 via the straightening bearings 53, allowing it to rotate flexibly. This ensures that the film passes smoothly through the straightening roller 5 during transport, preventing damage or deflection of the film due to excessive friction. The correction limiting component 54 restricts the axial movement of the correction cylinder 52, ensuring that the correction cylinder 52 maintains a stable axial position during rotation, thereby providing uniform and stable tension and correction for the film. The cooperation between the adjusting groove 56 and the fixing bolt 57 on the correction support plate 55 allows the installation position of the correction rod 51 to be finely adjusted according to actual needs, thereby adjusting the tension of the correction roller 5 on the film and further improving the applicability of the correction device.

[0043] like Figure 2 , Figure 6 , Figure 7The first edge-correcting sliding assembly 4 shown includes first edge-correcting blocks 41 disposed on both sides of the edge-correcting seat 1. The first edge-correcting blocks 41 are inclined to the edge-correcting seat 1. The first edge-correcting blocks 41 have a first edge-correcting groove 42 laterally formed. The edge-correcting frame 2 is provided with a first edge-correcting support plate. One end of the first edge-correcting support plate is fixedly connected to the edge-correcting frame 2, and the other end is provided with a first edge-correcting wheel 43. The first edge-correcting wheel 43 slides in cooperation with the first edge-correcting groove 42. The edge-correcting drive 6 drives the first edge-correcting wheel 43 to reciprocate within the first edge-correcting groove 42. The first edge-correcting blocks 41 are inclined to the edge-correcting seat 1, so that the first edge-correcting groove 42 has a certain guiding angle. When the edge-correcting drive 6 is running, it can drive the first edge-correcting wheel 43 to reciprocate stably within the first edge-correcting groove 42, thereby realizing the precise movement and positioning of the edge-correcting frame 2, effectively guiding the transmission direction of the film, ensuring the accuracy and reliability of the edge-correcting process, further improving the correction effect of the edge-correcting device on film deflection, and ensuring the winding quality.

[0044] The edge straightening frame 2 is provided with a second edge straightening sliding assembly 8 near the rotating component 3. The second edge straightening sliding assembly 8 includes a second edge straightening block 81 disposed on both sides of the edge straightening seat 1. The second edge straightening block 81 is inclined to the edge straightening seat 1 and inclined to the first edge straightening block 41. The second edge straightening block 81 is provided with a second edge straightening sliding groove 82 in the transverse direction. The edge straightening frame 2 is provided with a second edge straightening support plate. One end of the second edge straightening support plate is fixedly connected to the edge straightening frame 2, and the other end is provided with a second edge straightening wheel 83. The second edge straightening wheel 83 is slidably engaged with the second edge straightening sliding groove 82. The edge straightening drive component 6 drives the second edge straightening wheel 83 to reciprocate within the second edge straightening sliding groove 82. Since the first edge-correcting sliding component 4 is located at one end of the edge-correcting frame 2 relative to the rotating component 3, the rotation radius of the first edge-correcting sliding component 4 is relatively large. On the other hand, the second edge-correcting sliding component 8 is located at one end closer to the rotating component 3, and the sliding radius of the second edge-correcting sliding component 8 is relatively small. Therefore, the tilt angle between the first edge-correcting block 41 and the edge-correcting seat 1 is larger than the tilt angle between the second edge-correcting sliding component 8 and the edge-correcting seat 1, ensuring that the edge-correcting frame 2 has a larger edge-correcting range. At the same time, the first edge-correcting block 41 and the second edge-correcting block 81 are totaled in four parts and located at the four corners of the edge-correcting seat 1, which can provide stable support for the edge-correcting frame 2 and improve the stability of the edge-correcting frame 2 during the edge-correcting rotation process.

[0045] The rotating component 3 includes a rotating shaft 31 mounted on the edge straightening frame 2 and a seated bearing 32 mounted on the edge straightening seat 1. The rotating shaft 31 and the seated bearing 32 are rotatably coupled. The seated bearing 32 has a first mounting hole 33. The edge straightening seat 1 has a mounting plate 12. The mounting plate 12 has a second mounting hole 13 corresponding to the mounting hole 33. The seated bearing 32 is fixedly connected to the mounting plate 12 by connecting bolts provided in the first mounting hole 33 and the second mounting hole 13. The mounting plate 12 has a rotating hole 14 in the middle, and the end of the rotating shaft 31 can pass through the rotating hole 14. The seated bearing 32 is mounted on the mounting plate 12 of the edge-correcting seat 1. The rotating shaft 31 is rotatably engaged with the seated bearing 32, which makes the rotating part 3 stable and flexible in rotation. At the same time, the seated bearing 32 is fixedly connected to the mounting plate 12 through the connecting bolt, which enhances the stability of the structure and improves the convenience of maintenance. In addition, when the edge-correcting frame 2 rotates around the rotating part 3, the rotating part 3 can withstand a certain radial and axial load, ensuring the smooth rotation of the edge-correcting frame 2, thereby ensuring the stability and reliability of the edge-correcting device when correcting film deflection. Furthermore, when the rotating shaft 31 is rotatably engaged with the seated bearing 32, the end of the rotating shaft 31 can pass through the rotating hole 14 without contacting the mounting plate 12 or the edge-correcting seat 1, reducing the resistance when the rotating shaft 31 rotates and improving the stability of the rotation of the edge-correcting frame 2.

[0046] The working principle of this embodiment is as follows: When the film passes through the edge straightening device, it will contact the outer surface of the edge straightening cylinder 52 of the edge straightening roller 5 and the flattening sleeve 72 of the flattening roller 7, and drive the edge straightening cylinder 52 and the flattening sleeve 72 to rotate. When no deviation occurs, the middle part of the flattening sleeve 72 supports and flattens the film. When the film deviates, the servo cylinder 61 operates to drive the edge straightening frame 2 to rotate around the rotating shaft 31. At the same time, the first edge straightening wheel 43 slides in the first edge straightening groove 42, and the second edge straightening wheel 83 slides in the second edge straightening groove 82. The edge straightening roller 5 and the flattening roller 7 rotate synchronously with the edge straightening frame 2, so that the film is re-tensioned and flattened, and the edge straightening operation of the film is completed.
