Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a film flattening auxiliary device. Background Technology

[0002] By using mechanical structures to achieve efficient flattening of films, deformations such as wrinkles and ripples can be eliminated, ensuring material flatness and improving the accuracy of subsequent printing, coating and other processes. Stable clamping and flattening can reduce film displacement, wear and tear, and reduce material loss.

[0003] The film works in conjunction with tension control and mechanical guidance. The tension mechanism applies a constant tension to the film to eliminate wrinkles, and multiple sets of guide rollers are arranged at preset angles. The flatness of the roller surface is used to forcibly correct the film's orientation, and the adjustable spacing design can accommodate different thicknesses.

[0004] In existing technologies, some film flattening devices do not have components for easy clamping of the auxiliary device when installing the film. The film is unstable due to clamping, which causes displacement and slippage during the flattening process, resulting in a significant decrease in flattening accuracy and affecting the surface flatness and processing quality of the product. Therefore, a film flattening auxiliary device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a film flattening auxiliary device, which aims to improve the problem in the prior art where unstable clamping leads to displacement and sliding during the flattening process, resulting in a significant decrease in flattening accuracy and affecting the surface flatness and processing quality of the product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A film flattening auxiliary device includes a base plate and a fixed column. A motor is fixedly connected to the outer wall of the fixed column, and a threaded column is fixedly connected to the drive end of the motor. One of the fixed rings is fixedly connected to the outer wall of the fixed column. Multiple fixed plates are fixedly connected to the outer wall of one of the fixed rings. A round rod is fixedly connected to the inner wall of each of the multiple fixed plates. A connecting rod is rotatably connected to the outer wall of the round rod. A connecting plate is fixedly connected to the outer wall of the connecting rod. A flattening component for flattening the film after it is unfolded is installed on the outer wall of the base plate.

[0008] As a further description of the above technical solution:

[0009] The flattening assembly includes a base, two positioning plates are fixedly connected to the top of the base plate, an mounting plate is fixedly connected to the top of the base, one cylinder is fixedly connected to the top of the base, and another cylinder is fixedly connected to the top of the base plate.

[0010] As a further description of the above technical solution:

[0011] A sliding plate is slidably connected to the inner wall of the mounting plate, and one end of the base is fixedly connected to the outer wall of the base plate;

[0012] As a further description of the above technical solution:

[0013] The outer wall of the sliding plate is slidably connected to the groove opened in the mounting plate, and two fixing blocks are fixedly connected to the outer wall of the sliding plate.

[0014] As a further description of the above technical solution:

[0015] A support plate is fixedly connected to the outer wall of the connecting plate, and a membrane tube is detachably attached to the top of the support plate.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the threaded post is threadedly connected to another retaining ring, and a limit post is fixedly connected to the outer wall of the threaded post;

[0018] As a further description of the above technical solution:

[0019] Multiple limiting blocks are fixedly connected to the outer wall of the support plate, and the two sides of the film tube are in contact with the two sides of the limiting blocks.

[0020] As a further description of the above technical solution:

[0021] The inner walls of the two fixed blocks are fixedly connected to a round rod two, and the outer walls of the round rod two are rotatably connected to a flattening column.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor is started after the film tube is placed on the support plate. The motor drives the fixing ring to move, which in turn drives the fixing plate and the round rod to rotate the connecting rod, driving the three support plates to lift and clamp the film. At the same time, the limiting blocks of the support plates restrict the position of the film tube on both sides. This prevents displacement and slippage during the film flattening process, which would cause a significant decrease in flattening accuracy and affect the surface flatness and processing quality of the product.

[0024] 2. In this invention, the film is placed between two positioning plates on the base plate. The cylinder is activated, driving the sliding plate, fixing block, and other components to lower the flattening column. The cylinder stops when the outer wall of the flattening column contacts the film, and the film is flattened by the flattening column. This prevents residual wrinkles, ripples, or localized protrusions on the film surface from causing substandard material flatness, which directly affects the uniformity and precision of subsequent printing, coating, and other processes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a film flattening auxiliary device, including a base plate 2 and a fixing column 21. The base plate 2 is used to install components, and the fixing column 21 is used to fix a fixing ring 5. A motor 4 is fixedly connected to the outer wall of the fixing column 21. The motor 4 is used to drive the fixing ring 5 to clamp the film cylinder 14. A threaded column 12 is fixedly connected to the drive end of the motor 4. The threaded column 12 is used to drive the movement of the fixing ring 5. A fixing ring 5 is fixedly connected to the outer wall of the fixing column 21. The fixing ring 5 is used to fix a fixing plate 6. Multiple fixing plates 6 are fixedly connected to the outer wall of the fixing ring 5. Multiple fixing plates 6 are used to fix a round rod 7. A round rod 7 is fixedly connected to the inner wall of each fixing plate 6. The round rod 7 is used to fix a connecting rod 8. A connecting rod 8 is rotatably connected to the outer wall of the round rod 7. The connecting rod 8 is used to drive a support plate 10. A connecting plate 9 is fixedly connected to the outer wall of the connecting rod 8. The connecting plate 9 is used to connect the support plate 10 and the connecting rod 8. A flattening component for flattening the film cylinder 14 after it is unfolded is installed on the outer wall of the base plate 2.

[0033] A support plate 10 is fixedly connected to the outer wall of the connecting plate 9. The support plate 10 is used to support the diaphragm tube 14. The diaphragm tube 14 is detachably attached to the top of the support plate 10. A threaded post 12 is fixedly connected to one end of the drive shaft of the motor 4. The threaded post 12 is used to fix the limiting post 13. Another fixing ring 5 is threadedly connected to the outer wall of the threaded post 12. The limiting post 13 is fixedly connected to the outer wall of the threaded post 12. In order to prevent the moving ring 5 from being maximized, the limiting post 13 is fixedly connected to the outer wall of the support plate 10. Multiple limiting blocks 11 are fixedly connected to the outer wall of the support plate 10. The limiting blocks 11 are used to limit the swaying of the diaphragm tube 14 on both sides when it moves. The two sides of the diaphragm tube 14 are in contact with the two sides of the limiting blocks 11.

[0034] Reference Figures 2 to 4 The flattening assembly includes a base 1 and a base plate 2. Two positioning plates 3 are fixedly connected to the top of the base 1 for better flattening. A mounting plate 15 is fixedly connected to the top of the base 1 for limiting the movement trajectory of the sliding plate 17. One cylinder 16 is fixedly connected to the top of the base 1 for supporting the sliding plate 17. Another cylinder 16 is fixedly connected to the top of the base plate 2. The sliding plate 17 is slidably connected to the inner wall of the mounting plate 15 for mounting the fixing block 18. One end of the base 1 is fixedly connected to the outer wall of the base plate 2. The outer wall of the sliding plate 17 is slidably connected to the groove opened in the mounting plate 15. Two fixing blocks 18 are fixedly connected to the outer wall of the sliding plate 17 for fixing the second round rod 19. The inner wall of the fixing block 18 is fixedly connected to the second round rod 19 for connecting the flattening column 20. The outer wall of the second round rod 19 is rotatably connected to the flattening column 20 for flattening the film cylinder 14.

[0035] Working principle: When the film needs to be clamped, the film tube 14 is first placed on the support plate 10. At this time, the motor 4 is started, and the fixed ring 5 connected to the drive end of the motor 4 begins to move. The movement of the fixed ring 5 drives the fixed plate 6 and the round rod 7 to move. When the fixed plate 6 and the round rod 7 move, the connecting rod 8 rotates. The rotation of the connecting rod 8 drives the three support plates 10 to lift up respectively to clamp the film tube 14. The two limit blocks 11 on the support plate 10 contact the two sides of the film tube 14 to prevent the sides from being unstable, so that the film tube 14 can be clamped. This avoids displacement and sliding during the film flattening process, which would cause a significant decrease in flattening accuracy and affect the surface flatness and processing quality of the product.

[0036] When it is necessary to flatten the clamped film, first pull out the film and place it on the base plate 2. Place the two sides of the film between the two positioning plates 3. At this time, activate the two cylinders 16, and the sliding plate 17 moves downward. The downward movement of the sliding plate 17 drives the fixing block 18 to move downward, which in turn drives the round rod 19 to move downward, causing the flattening column 20 to descend. When the outer wall of the flattening column 20 touches the film, the cylinder 16 stops moving. When the film passes the outer wall of the flattening column 20, the flattening of the film is completed, thereby avoiding residual wrinkles, ripples or local protrusions on the film surface, which would lead to substandard material flatness and directly affect the uniformity and accuracy of subsequent printing, coating and other processes.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
