Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of film manufacturing equipment, and specifically relates to a swing-arm floating roller for a peeling chamber. Background Technology
[0002] Taking polyimide film as an example, after casting, it is peeled off from a steel strip to obtain the film, which is then conveyed into a peeling chamber. Inside the peeling chamber, it undergoes a certain longitudinal (length direction) stretching. Then, both ends of the film are fixed and it is fed into a transverse stretching mechanism. Maintaining a certain tension and stretching effect in the peeling chamber requires the installation of floating rollers. Existing floating rollers, for example, are vertically positioned via linear guide rail assemblies, enabling vertical movement. This structure is relatively complex and occupies a large space. Furthermore, some existing linear guide rail assemblies have excessive driving force, are not conducive to high-precision fine-tuning, or suffer from vibration and instability during the driving process, which may damage the freshly peeled film and make it difficult to accurately achieve the required tension. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a swing arm type floating roller for the peeling chamber, which solves the problems of large space occupation and poor control method or precision of existing floating rollers, so as to better match the application scenario of the peeling chamber and provide better tension and stretching effect for the peeled film.
[0004] According to the technical solution of this utility model, this utility model provides a swing arm type floating roller for a stripping chamber, including an L-shaped swing arm, the L-shaped corner of the L-shaped swing arm is rotatably connected to the mounting side plate, the end of the long side of the L-shaped swing arm is rotatably connected to the floating roller, the end of the short side of the L-shaped swing arm is rotatably connected to the telescopic cylinder, and the other end of the telescopic cylinder is rotatably connected to the mounting side plate.
[0005] In some embodiments, a first guide roller and a second guide roller are rotatably connected to the mounting side plate, with the first guide roller and the second guide roller located above the left and right sides of the floating roller, respectively.
[0006] In some embodiments, the first guide roller is located to the left of the second guide roller, the film conveying direction is from left to right, the L-shaped corner of the L-shaped swing arm is located to the left of the floating roller, and the height of the second guide roller is lower than that of the first guide roller.
[0007] In some embodiments, a central shaft is provided at the L-shaped corner of the L-shaped swing arm, and a seated bearing is provided on the mounting side plate, with the central shaft connected to the seated bearing.
[0008] In some embodiments, the telescopic cylinder includes a telescopic rod and a cylinder body that are slidably connected. The end of the telescopic rod away from the cylinder body is rotatably connected to an L-shaped swing arm via a pin, and the end of the cylinder body away from the telescopic rod is rotatably connected to a mounting side plate via a tailstock.
[0009] In some embodiments, both ends of the floating roller are provided with L-shaped swing arms, telescopic cylinders and mounting side plates, and the structures at both ends of the floating roller are symmetrical; the ends of the first guide roller and the second guide roller are respectively installed and connected to the mounting side plates on both sides; the length directions of the floating roller, the first guide roller and the second guide roller are parallel.
[0010] In some embodiments, the long side of the L-shaped swing arm is arranged laterally, the short side of the L-shaped swing arm is located below the long side of the L-shaped swing arm, and the telescopic cylinder is located below the long side of the L-shaped swing arm.
[0011] In some implementations, the angle between the long and short sides of the L-shaped swing arm is 80° to 100°.
[0012] In some implementations, the angle between the long side of the L-shaped swing arm and the extension / retraction direction of the telescopic cylinder is 0° to 45°.
[0013] In some implementations, the telescopic cylinder is a pneumatic cylinder or a hydraulic cylinder.
[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows: The swing-arm floating roller of this invention for the peeling chamber adopts an L-shaped swing-arm structure, forming a special lever arm shape. This allows the position of the floating roller to be adjusted within a small range by rotating around a central axis, ensuring the continuity and stability of the adjustment process. Furthermore, the short side of the lever arm is used for driving, forming a force-reducing lever, which helps control the positional accuracy and tensile tension. At the same time, the bending angle of the L-shape improves the space utilization rate, allowing the floating roller to form a smaller modular structure, which is easy to install. This allows for better spatial layout in the peeling chamber and provides the required tension and stretching effect for the newly peeled film, which helps improve the quality and yield of film products.

[0019] This invention provides a swing-arm type floating roller for a peeling chamber, which solves the problems of large space occupation and poor control method or precision of existing floating rollers, and achieves better matching of peeling chamber application scenarios, providing better tension and stretching effect for the peeled film.
[0020] Please see Figures 1 to 3 This invention discloses a swing-arm type floating roller for a stripping chamber, comprising an L-shaped swing arm 1. The L-shaped corner of the swing arm 1 is rotatably connected to a mounting side plate 2. The long side of the L-shaped swing arm 1 is rotatably connected to a floating roller 3, and the short side of the L-shaped swing arm 1 is rotatably connected to a telescopic cylinder 4. The other end of the telescopic cylinder 4 is rotatably connected to the mounting side plate 2. This design allows the L-shaped swing arm 1 to rotate by controlling the extension and retraction of the telescopic cylinder 4, thereby changing the position of the floating roller 3.
[0021] Furthermore, a first guide roller 5 and a second guide roller 6 are rotatably connected to the mounting side plate 2, with the first guide roller 5 and the second guide roller 6 located above the left and right sides of the floating roller 3, respectively. This solution forms a complete modular floating roller assembly with guide rollers, which is easier to apply.
[0022] Preferably, the first guide roller 5 is located to the left of the second guide roller 6, the film conveying direction is from left to right, the L-shaped corner of the L-shaped swing arm 1 is located to the left of the floating roller 3, and the height of the second guide roller 6 is lower than that of the first guide roller 5. In this scheme, the setting of the first guide roller 5 and the second guide roller 6 matches the way the floating roller 3 is rotated and adjusted. For example, when the floating roller 3 is adjusted downward, it is actually to the lower left, which is close to the perpendicular direction of the line connecting the first guide roller 5 and the second guide roller 6, thus achieving a more uniform and gentle force application effect.
[0023] For example Figure 1 In the illustrated embodiment, a central shaft 7 is provided at the L-shaped corner of the L-shaped swing arm 1, and a seated bearing 8 is provided on the mounting side plate 2. The central shaft 7 is connected to the seated bearing 8. The main body of the L-shaped swing arm 1 is, for example, a plate-shaped casting or welded part. The central shaft 7 protrudes from the L-shaped swing arm 1. The seated bearing 8 includes a bearing housing that is mounted and connected to the mounting side plate 2, and a bearing. The outer ring of the bearing is embedded in the bearing housing, and the inner ring of the bearing is sleeved outside the central shaft 7, thus forming a stable rotational connection and facilitating component processing and installation.
[0024] The telescopic cylinder 4 includes a telescopic rod and a cylinder body that are slidably connected. The end of the telescopic rod away from the cylinder body is rotatably connected to the L-shaped rocker arm 1 via a pin 9. The end of the cylinder body away from the telescopic rod is rotatably connected to the mounting side plate 2 via a tailstock 10. The telescopic cylinder 4 is, for example, a pneumatic cylinder or a hydraulic cylinder.
[0025] Please see Figure 2 , Figure 3In this embodiment, each roller is relatively long to accommodate wider films. Specifically, both ends of the floating roller 3 are equipped with L-shaped swing arms 1, telescopic cylinders 4, and mounting side plates 2, and the structures at both ends of the floating roller 3 are symmetrical. The ends of the first guide roller 5 and the second guide roller 6 are respectively connected to the mounting side plates 2 on both sides. This design ensures that the length directions of the floating roller 3, the first guide roller 5, and the second guide roller 6 are parallel. It is conceivable that in some applications where the roller length is shorter, the mounting side plate 2 can be provided only on one side, with the other end of the roller suspended.
[0026] Please see again Figure 1 Preferably, the long side of the L-shaped swing arm 1 is arranged horizontally, and the short side of the L-shaped swing arm 1 is located below the long side of the L-shaped swing arm 1. The telescopic cylinder 4 is located below the long side of the L-shaped swing arm 1, thus making the structure more compact and occupying less space. In a more specific embodiment, the angle between the long side and the short side of the L-shaped swing arm 1 is 80° to 100°, further for example, 90°; and / or, the angle between the long side of the L-shaped swing arm 1 and the telescopic direction of the telescopic cylinder 4 is 0° to 45°, further for example, Figure 1 In the state shown, the angle between the long side of the L-shaped swing arm 1 and the extension / retraction direction of the telescopic cylinder 4 is 0°.
[0027] In summary, the swing-arm floating roller of this invention for the peeling chamber adopts an L-shaped swing-arm structure, forming a special lever arm shape. This allows the position of the floating roller to be adjusted within a small range by rotating around a central axis, ensuring the continuity and stability of the adjustment process. Furthermore, the short side of the lever arm is used for driving, forming a lever that requires less effort, which helps control the positional accuracy and tensile tension. At the same time, the bending angle of the L-shape improves the space utilization rate, allowing the floating roller to form a smaller modular structure, which is easy to install. This allows for better spatial layout in the peeling chamber and provides the required tension and stretching effect for the newly peeled film, which helps improve the quality and yield of film products.
