Abstract
Description
Technical Field
[0001] The invention relates to the technical field of film winding, in particular to a film winding device capable of improving wrinkling phenomenon. Background Art
[0002] Film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. The scientific explanation of film is: a two-dimensional material formed by atoms, molecules or ions deposited on the surface of a substrate. Examples: optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. Film is widely used in electronics, machinery, printing and other industries. After the film is produced, it is usually first wound and collected by a roller, and then the film on the roller is divided into rolls according to the required film width and thickness by the unwinding mechanism and the rewinding mechanism for packaging and sale. In addition to the common single-layer film in life, there are also some double-layer films.
[0003] When the existing film winding equipment winds up a double-layer film, the change in film thickness at the unwinding end and the winding end leads to an unbalanced front and rear tension, which can easily cause the film from the unwinding end to the winding end to be loose inside and tight outside, and the outer film will wrinkle the inner film. In addition, when the double-layer film is wound, some film segments are prone to air in the interlayer due to improper operation, and are squeezed when transported to the winding end, causing film overlap in the film segment containing the air interlayer. In the subsequent winding, vertical wrinkles are caused at this position, resulting in different pulling forces on both sides of the same film segment, so that the film wrinkles become more and more serious during subsequent winding. Summary of the invention
[0004] The technical solution of the present invention is aimed at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a film winding device with improved wrinkling phenomenon, so as to solve the problems raised in the above background technology such as unbalanced tension when winding a double-layer film and the presence of air in the interlayer causing wrinkles in the film when winding.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a film winding device for improving wrinkling phenomenon, comprising a workbench, a controller is installed on the top of the workbench, and a rewinding mechanism is installed on one side of the top of the workbench, and a rewinding mechanism is installed on the other side of the top of the workbench, a supporting roller is installed in the middle of the top of the workbench, and transverse anti-wrinkle mechanisms are symmetrically arranged on both sides of the supporting roller, and a longitudinal anti-wrinkle mechanism is arranged on the side of the rewinding mechanism close to the tension adjustment mechanism.
[0006] Preferably, the transverse anti-wrinkle mechanism includes a cylinder symmetrically arranged on the top of the workbench, and a piston slidingly matched with the cylinder is arranged inside the cylinder, the top of the piston is connected to a support column passing through the top of the cylinder, a first spring located on the outside of the support column is fixedly connected between the top of the support column and the piston, and a tension roller is installed on the top of the support column.
[0007] Preferably, the bottoms of the two groups of cylinders are connected through pipelines, and the tops of the cylinders are provided with air holes.
[0008] Preferably, the longitudinal anti-wrinkle mechanism includes two groups of side panels symmetrically arranged on one side of the winding mechanism, the outer walls of the two groups of side panels are provided with symmetrical detection components, and the two groups of side panels are provided with symmetrical leveling components on one side of the detection components.
[0009] Preferably, the detection component includes a support frame arranged on the outer wall of the side panel, and the support frame is arranged as a U-shaped structure, the internal rotation of the support frame is connected to the first rotating shaft, and an angle sensor is installed on the top of the support frame, the receiving end of the angle sensor is connected to the first rotating shaft, the outer wall of the support frame is located on the outside of the first rotating shaft and a cover body is arranged, a vortex spring is connected between the first rotating shaft and the cover body, and a detection roller is arranged on the outer wall of the first rotating shaft.
[0010] Preferably, the leveling assembly includes a support plate arranged on the outer wall of the side plate, an electric telescopic rod is installed in the middle of the support plate, the telescopic end of the electric telescopic rod is rotatably connected to a turntable, a motor is installed on the top of the support plate on one side of the electric telescopic rod, the output end of the motor is connected to a second rotating shaft that passes through the support plate, a first gear that slides with the second rotating shaft is provided on the outer wall of the second rotating shaft, a second gear that meshes with the first gear is provided on the top of the support plate, and the telescopic end of the electric telescopic rod is connected to a connecting frame located on the outside of the first gear.
[0011] Preferably, rubber blocks are arranged at equal angles on the bottom of the turntable, a limit strip slidingly matched with the first gear is arranged on the outer wall of the second rotating shaft, the connecting frame is arranged as a U-shaped structure, and a through hole located outside the second rotating shaft is arranged inside the connecting frame, and a ball is arranged on the outer wall of the connecting frame.
[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention is provided with a transverse wrinkle-proof mechanism. As the thickness of the film roll of the winding mechanism increases, the film tension increases and the pressure on the right tension roller increases. The tension roller drives the support column to push the piston, thereby reducing the tension of the film at the winding end, and the piston pulls the first spring, while the thickness of the film roll of the left unwinding mechanism decreases. The reduced film tension makes the film on the top of the left tension roller loose, then the right piston slides to press the oil into the left cylinder through the pipeline, so that the left piston slides up, and the left tension roller moves up to hold the loosened film, thereby increasing the film tension at the unwinding end. Since the film thickness changes of the unwinding mechanism and the winding mechanism are synchronous and the same, the tension of the film is constant during unwinding and winding, thereby avoiding wrinkles generated during transverse transportation. The present invention is provided with a longitudinal wrinkle-proof mechanism. When film overlap occurs after air exists in the interlayer of the double-layer film, under the action of the detection component, the wrinkles formed by the film overlap can cause the corresponding detection roller to deflect by a certain angle. The angle sensor controls the extension of the electric telescopic rod through the controller. Under the action of the leveling component, the motor drives the turntable to rotate in the opposite direction of the deflection direction of the detection roller. After the electric telescopic rod is extended, the turntable moves downward to drive the bottom rubber block to contact the film surface. The greater the deflection angle of the detection roller, the greater the contact pressure between the rubber block and the film. As the turntable continues to rotate, the rubber blocks with equal angles at the bottom are smoothed outwardly at the film overlap, so that the film arriving at the winding mechanism is in a flat state, reducing wrinkles formed due to the air in the film interlayer. In summary, with the joint action of the transverse anti-wrinkle mechanism and the longitudinal anti-wrinkle mechanism, wrinkles caused by tension during transverse transportation can be avoided, and wrinkles formed by air in the film interlayer can be reduced, thereby better improving the wrinkling phenomenon when the film is rolled up.

A vortex spring 705 is connected between the first rotating shaft 702 and the cover body 704, and a detection roller 706 is arranged on the outer wall of the first rotating shaft 702.
[0021] The leveling assembly includes a support plate 708 arranged on the outer wall of the side plate 7, an electric telescopic rod 709 is installed in the middle of the support plate 708, the telescopic end of the electric telescopic rod 709 is rotatably connected to a turntable 710, the top of the support plate 708 is located on one side of the electric telescopic rod 709 and a motor 711 is installed, the output end of the motor 711 is connected to a second rotating shaft 712 that passes through the support plate 708, the outer wall of the second rotating shaft 712 is provided with a first gear 713 that slides with it, the top of the support plate 708 is provided with a second gear 714 that meshes with the first gear 713, and the telescopic end of the electric telescopic rod 709 is connected to a connecting frame 715 located on the outside of the first gear 713.
[0022] Rubber blocks are arranged at equal angles at the bottom of the turntable 710, a limit strip slidingly matched with the first gear 713 is arranged on the outer wall of the second rotating shaft 712, the connecting frame 715 is arranged as a U-shaped structure, and a through hole located on the outside of the second rotating shaft 712 is arranged inside the connecting frame 715, and a ball is arranged on the outer wall of the connecting frame 715.
[0023] Working principle: When using the film winding device for improving wrinkling, first, the unwinding speed of the unwinding mechanism 3 is the same as the winding speed of the winding mechanism 4, and the axes of the unwinding mechanism 3 and the winding mechanism 4 are located at the same height, and the two groups of cylinders 6 are located below the piston 601 and the pipelines are filled with oil. As the thickness of the film roll of the winding mechanism 4 increases, the film tension increases and the pressure on the right tension roller 604 increases. The tension roller 604 drives the support column 602 to push the piston 601, reducing the tension of the film at the winding end, and the piston 601 pulls the first spring 603, and the film roll thickness of the left unwinding mechanism 3 decreases, and the film tension decreases, causing the film on the top of the left tension roller 604 to become loose, then the right piston 601 slides to press the oil into the left cylinder 6 through the pipeline, causing the left piston 601 to slide up, causing the left tension roller 604 to move up to hold the loosened film, thereby increasing the film tension at the unwinding end. Since the film thickness changes of the unwinding mechanism 3 and the winding mechanism 4 are synchronized and the same, the film tension is constant during unwinding and winding, avoiding wrinkles; Then, the controller 2 is electrically connected to the angle sensor 703 and the electric telescopic rod 709, and the motor 711 has the same unwinding speed as the unwinding mechanism 3 and the rewinding speed as the rewinding mechanism 4. Figure 2 In the leveling assembly, the upper motor 711 drives the turntable 710 to rotate clockwise, and the lower motor 711 drives the turntable 710 to rotate counterclockwise. In the leveling assembly, the motor 711 drives the second shaft 712 to rotate when it rotates. Due to the limit strip on the outer wall of the second shaft 712, the second shaft 712 drives the first gear 713 to rotate, the first gear 713 drives the second gear 714 to rotate, and the second gear 714 drives the turntable 710 to rotate; Finally, as the film roll thickness of the winding mechanism 4 increases, the right tension roller 604 moves downward adaptively, so that the tilt angle of the film remains unchanged. If there is air inside the interlayer of the double-layer film, it is squeezed by the right tension roller 604, so that the film where the air exists overlaps. As the winding mechanism 4 pulls, the film pulling force at the overlap is relatively large. Figure 2 and Figure 7 As shown, the film can be divided into two sections by a symmetrical detection assembly, the detection roller 706 just touches the film surface without pressure, and the rubber block at the bottom of the turntable 710 does not touch the film surface. When there are no overlapping film wrinkles on the film surface, the film passes the bottom of the detection roller 706 normally, which can drive the detection roller 706 to rotate. When overlapping film wrinkles appear on the film surface, when passing the bottom of the corresponding detection roller 706, the increase in pulling force will increase the resistance to the detection roller 706, so that the film drives the corresponding detection roller 706 to deflect at a certain tilt angle. The deflection direction of the detection roller 706 is opposite to the rotation direction of the corresponding turntable 710. The detection roller 706 drives the first rotating shaft 702 to rotate, and the first rotating shaft 702 drives the vortex spring 705 to rotate and deform. At the same time, the angle sensor 703 can detect the deflection angle of the detection roller 706, and the angle sensor 703 controls the extension of the electric telescopic rod 709 through the controller 2. The electric telescopic rod 709 pushes the turntable 710 to move downward, and the telescopic end of the electric telescopic rod 709 drives the connecting frame 715 to move downward synchronously, so that the first gear 713 slides synchronously. Since the turntable 710 is limited by the limit bar when sliding down the outer wall of the turntable 710, the first gear 713 always follows the rotation of the second shaft 712 and is always engaged with the second gear 714. Then, when the turntable 710 moves downward, it drives the bottom rubber block to contact the surface of the film. The greater the deflection angle of the detection roller 706, the greater the contact pressure between the rubber block and the film. As the turntable 710 continues to rotate, the rubber blocks with equal angles at the bottom are smoothed outward toward the overlapping film, so that the film reaching the winding mechanism 4 is in a flat state, reducing the wrinkles formed by the presence of air in the film interlayer. When there is no overlapping film at the back, the detection roller 706 is reset under the action of the vortex spring 705. After detection by the angle sensor 703, the controller 2 controls the electric telescopic rod 709 to reset.
