Description

Technical Field

[0001] The present invention relates to the technical field of film processing, and particularly to a side leveling mechanism for film processing. Background Art

[0002] During the production and processing of thin films, after the film materials go through processes such as extrusion, stretching, and cooling, wrinkles, wavy undulations, and other uneven phenomena often occur on their sides. These uneven problems not only affect the appearance quality of the thin films but may also lead to an increase in the defective rate in subsequent processes such as printing, laminating, and slitting. In severe cases, it may even cause waste of materials. Currently, most of the common film side leveling mechanisms on the market adopt a simple roller pressing method. However, this traditional leveling mechanism has many defects. On the one hand, it is difficult to control the pressure of the rollers.

[0021] Please refer to Figure 1-6, the present invention provides a technical solution for a side leveling mechanism of film processing: including an equipment frame 1, the equipment frame 1 includes a base 2, columns 3, a top support plate 4, a lifting assembly, and an upper leveling assembly. The columns 3 are symmetrically and fixedly installed on both sides of the base 2, the top of the columns 3 is fixedly connected to the top support plate 4, the lifting assembly includes a support beam 5, a mounting seat 6, and a lifting cylinder 7.

The leveling arms 8 are movably installed on both sides of the support beam 5, and the driving device includes a support rod 9, a movable turntable 10, and a rotating motor 11. The rotating motor 11 drives the leveling arms 8 to move closer or expand synchronously on the support beam 5 through the support rod 9, and a bottom leveling assembly is arranged on the upper surface of the base 2.

[0022] Further, the leveling arm 8 includes a movable block 12, an adjustable bracket 13, and a pressing roller 14. The movable block 12 is movably installed on the support beam 5, a slide rail 15 is fixedly arranged at the bottom of the support beam 5, a connecting column 16 is fixedly installed at the top of the movable block 12, the connecting column 16 is movably connected to the support rod 9, and the pressing roller 14 is installed at the bottom of the movable block 12 through the adjustable bracket 13.

[0023] In this embodiment, the material of the pressing roller 14 is preferably rubber to increase the friction with the film material and avoid scratching the film material at the same time. The design of the adjustable bracket 13 allows the position of the pressing roller 14 to be adjusted according to the thickness and hardness of the film material, ensuring the consistency and stability of the leveling effect. During the leveling process, the rotating motor 11 drives the leveling arms 8 to move closer or expand synchronously on the support beam 5 through the support rod 9, realizing effective leveling of the side of the film material. When the film material passes by, the pressing roller 14 will gently press the side of the film material to keep it flat, thereby improving the quality and appearance effect of the film product.

[0024] Furthermore, an installation groove 17 is provided inside the adjustable bracket 13. An adjusting screw rod 18 is installed inside the installation groove 17. Both ends of the adjusting screw rod 18 are rotatably connected to the two side walls of the installation groove 17.

The top of the moving block 20 is fixedly connected to the movable block 12.

[0025] In this embodiment, the driving of the adjusting motor 19 causes the moving block 20 to move axially along the adjusting screw rod 18 in the installation groove 17, thereby adjusting the position of the pressing roller 14 relative to the movable block 12 and realizing the effective leveling of films with different widths. By precisely controlling the rotation angle and speed of the adjusting motor 19, the adjustment of the position of the pressing roller 14 can be achieved.

[0026] Furthermore, a pressure adjusting mechanism is further provided on the adjustable bracket 13. The pressure adjusting mechanism includes a vertical rod 21, a horizontal rod 22, and an adjusting spring 23.

The adjusting spring 23 is installed on the adjustable bracket 13, and the bottom of the adjusting spring 23 is fixedly connected to the horizontal rod 22. A screw rod 24 is installed at the top of the adjusting spring 23. The screw rod 24 is threadedly connected to the adjustable bracket 13. A knob 25 is fixedly installed at the top of the screw rod 24.

[0027] In this embodiment, by rotating the knob 25, the screw rod 24 can be driven to move up and down on the adjustable bracket 13, thereby compressing or stretching the adjusting spring 23 and realizing the adjustment of the pressure applied to the pressing roller 14. The leveling arm 8 can flexibly adjust the pressing force according to the hardness and thickness of different film materials, ensuring the leveling effect while avoiding the risk of damage to the film material due to excessive pressure. In addition, the movable hinge structure of the horizontal rod 22 and the vertical rod 21 enables the pressing roller 14 to be adjusted at an angle within a certain range, better adapting to the minute undulations on the surface of the film material and improving the accuracy and efficiency of leveling.

[0028] Furthermore, the bottom leveling assembly includes a driving roller 26 and a driven roller 27, the driving roller 26 is connected to a driving motor, a transmission belt 28 is sleeved between the driving roller 26 and the driven roller 27, a brush 29 is provided on the upper surface of the transmission belt 28, a film to be processed 30 is placed on the upper surface of the transmission belt 28, a support platform 39 is installed inside the transmission belt 28, and the support platform 39 is fixedly installed on the base 2.

[0029] In this embodiment, the active roller 26 drives the transmission belt 28 to rotate through the driven roller 27. During the outward rotation of the transmission belt 28, the brush 29 can contact the bottom of the film 30 to be processed, so that the hem at the bottom of the film 30 to be processed can be smoothed, thereby ensuring the flatness of the bottom of the film 30 to be processed.

[0030] Furthermore, two groups of the bottom leveling components are provided, and are respectively installed below the leveling arms 8 . The leveling arms 8 and the bottom leveling components are located on both sides of the film 30 to be processed.

[0031] In this embodiment, each group of bottom leveling components can independently level the edge of the film to be processed 30, thereby improving the leveling efficiency and leveling quality.

[0032] Furthermore, the driving device also includes a mounting bracket 31, the mounting bracket 31 is fixed on the top of the support beam 5, the rotating motor 11 is fixedly mounted above the mounting bracket 31, the bottom of the rotating motor 11 is transmission-connected to the movable turntable 10 through a motor shaft, and the bottom of the movable turntable 10 is rotatably mounted on the support beam 5.

[0033] In this embodiment, the mounting bracket 31 improves the stability of the rotating motor 11, and the rotating motor 11 achieves smooth rotation of the movable turntable 10 through the precise connection between the motor shaft and the movable turntable 10. Through the coordinated operation of the mounting bracket 31, the rotating motor 11 and the movable turntable 10, the side leveling of the film 30 to be processed is precisely controlled, and the quality and efficiency of film processing are effectively improved.

[0034] Furthermore, two eccentric shafts 32 are symmetrically mounted on the movable turntable 10 , and two groups of support rods 9 are provided, and one end of the support rod 9 is movably hinged to the eccentric shaft 32 , and the other end is movably hinged to the corresponding leveling arm 8 .

[0035] In this embodiment, when the movable turntable 10 rotates, it will push or pull the leveling arms 8 on both sides through the support rods 9 to move synchronously inward or outward, so as to drive the pressing rollers 14 at the bottom to contact both sides of the film to be processed 30 through this moving method, thereby leveling the sides of the film to be processed 30. This synchronous moving method of the leveling arms 8 not only ensures the stability and uniformity of the leveling process, but also greatly improves the leveling efficiency.

[0036] Furthermore, a film blowing mechanism 33 is fixedly installed at the bottom of the support beam 5. The film blowing mechanism 33 includes a blower 34 and a mounting bracket 35. The top of the mounting bracket 35 is fixedly connected to the bottom of the support beam 5. The blower 34 is fixedly installed at the bottom of the mounting bracket 35. The air outlet of the blower 34 corresponds to the positions on both sides of the film to be processed 30.

[0037] In this embodiment, the blower 34 can blow air towards both sides of the film to be processed 30, thereby effectively leveling the sides of the film to be processed 30. When the blower 34 is started, the generated airflow can flow along the sides of the film to be processed 30, and the uneven parts on the sides are smoothed by the force of the wind, making the sides of the film smoother.

[0038] Furthermore, a fixing mechanism is installed at the bottom of the base 2. The fixing mechanism includes fixing blocks 36 and bolts 37. The fixing blocks 36 are fixedly installed at the four corners of the bottom of the base 2. Threaded holes are provided inside the fixing blocks 36. The bolts 37 are threadedly installed inside the threaded holes. A pressing plate 38 is installed at the top of the bolts 37, and an anti-slip pad is provided on the pressing plate 38.

[0039] In this embodiment, by rotating the bolts 37, the pressure of the pressing plate 38 on the fixed position can be adjusted to further ensure the stable installation of the mechanism. The design of the fixing mechanism enables the film processing side leveling mechanism to be conveniently installed on different workbenches, improving its applicability and flexibility.

[0040] Working principle: When in use, first fix the equipment frame 1 at a suitable position through the fixing mechanism, and then start the lifting cylinder 7. The telescopic end of the lifting cylinder 7 extends, driving the support beam 5 and the upper leveling assembly to descend until the pressing rollers 14 contact the sides of the film to be processed 30. Then, start the rotary motor 11. The rotary motor 11 drives the movable turntable 10 to rotate through the motor shaft, and the eccentric shaft 32 on the movable turntable 10 rotates accordingly. Since one end of the eccentric shaft 32 is movably hinged to one end of the support rod 9, and the other end of the support rod 9 is movably hinged to the leveling arm 8, the rotation of the eccentric shaft 32 will drive the leveling arms 8 to move synchronously closer or expand on the support beam 5, thereby leveling the sides of the film to be processed 30.

[0041] Meanwhile, the adjusting motor 19 inside the adjustable bracket 13 is started, and the output end of the adjusting motor 19 drives the adjusting screw 18 to rotate. Since the moving block 20 is threadedly connected to the adjusting screw 18, the moving block 20 will move within the installation groove 17, thereby driving the movable block 12 and the pressing roller 14 to move left and right, realizing the adjustment of the width of the pressing roller 14. In addition, by rotating the knob 25, the screw 24 can be driven to rotate on the adjustable bracket 13, thereby adjusting the compression degree of the adjusting spring 23, so as to realize the fine adjustment of the pressing pressure of the pressing roller 14.

[0042] During the leveling process, the blower 34 of the film blowing mechanism 33 is started to blow air to both sides of the film to be processed 30, which helps to flatten the film to be processed 30. Meanwhile, the drive motor of the bottom leveling assembly is started to drive the driving roller 26 to rotate. The driving roller 26 drives the driven roller 27 to rotate through the transmission belt 28, and the brush 29 on the transmission belt 28 moves accordingly to clean and level the bottom of the film to be processed 30. The entire leveling process has a high degree of automation, good leveling effect, and can perform different degrees of leveling treatment on the side edges of the film to be processed 30 as needed, greatly improving the production efficiency and product quality of film processing.
