Description

Technical Field

[0001] This utility model relates to the field of film processing winding technology, specifically a winding device for thermoplastic polyurethane film processing. Background Technology

[0002] Thermoplastic polyurethane is a linear block copolymer made by polymerization of diisocyanate, polyol and chain extender. It combines the high elasticity of rubber and the processing performance of plastic. Its film products are widely used in many fields due to their excellent comprehensive performance. After the thermoplastic polyurethane film is processed, the continuously produced film products need to be sorted into rolls for easy storage, transportation and subsequent processing. This process requires the use of a winding device to wind up the film.

[0003] For example, the authorized publication number CN218595633U discloses a winding device for processing plastic film, which includes a base. The left and right sides of the top front end of the base are fixedly connected to fixed brackets, and the rear end of the base is fixedly connected to a sliding base. The top center of the sliding base has sliding grooves at both ends. The left and right ends of the sliding base are fixedly connected to servo motors, and the output ends of the servo motors are fixedly connected to ball screws. A roller bearing is provided between the two ball screws. When using this device, it is necessary to adjust the distance between the two sliding brackets so that the distance between the through shafts is greater than the length of the collection roll before the collection roll can be installed. During this process, the collection roll is suspended in the air for a certain period of time, making installation and disassembly difficult. Utility Model Content

[0004] The purpose of this invention is to provide a winding device for processing thermoplastic polyurethane films, so as to solve the problem mentioned in the background art that the collection roll is in a suspended state for a certain period of time, making installation and disassembly difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winding device for processing thermoplastic polyurethane film, comprising a fixed frame, with support legs fixedly connected to the four corners of the bottom of the fixed frame, and mounting base plates fixedly connected to the bottom of each support leg. An adjustment assembly is internally connected to the fixed frame, and two movable frames are connected to both ends of the adjustment assembly. A clamping support assembly is installed in the middle of one side of one movable frame, and a pressing and limiting assembly is fixedly connected to the top of the side of the movable frame. A driving assembly is fixedly installed on the side of the other movable frame. Film limiting assemblies are fixedly connected to the sides of the two movable frames that are close to each other. When installing and removing the film core, this device provides a certain supporting force to the core through the support roller, limiting plate, limiting roller, inner support plate, and inner support claw, making the installation and removal of the film core more stable and improving operational safety. Simultaneously, the limiting roller reduces friction with the film, lowering friction at the film's corners.

[0006] Preferably, the adjustment assembly includes a bidirectional lead screw, which is rotatably connected to the middle of the fixed frame. Two supporting horizontal shafts are symmetrically fixed inside the fixed frame and are symmetrically distributed on both sides of the bidirectional lead screw. One end of the bidirectional lead screw passes through the side wall of the fixed frame and is fixedly connected to an adjusting wheel. The adjusting wheel drives the bidirectional lead screw to rotate, providing power for the rotation of the mounting horizontal plate and adjusting the distance between the two mounting horizontal plates.

[0007] Preferably, the clamping support assembly includes two support rollers, which are symmetrically fixedly connected to the side of a movable frame. A rotating top plate is rotatably connected to the middle of the side of the two movable frames that are close to each other. The rotating top plate limits the end of the core and supports the core through the support rollers, thus ensuring the stability of the core during use.

[0008] Preferably, the pressing and limiting assembly includes a mounting plate, which is fixedly connected to the top side of a movable frame. An adjusting screw is threadedly connected to the middle of the mounting plate, and a lifting frame is rotatably connected to the bottom end of the adjusting screw. A pressure roller is rotatably connected inside the lifting frame. Two limiting rods are symmetrically fixedly connected to the bottom end of the mounting plate. The two limiting rods extend through the top plate of the lifting frame. The lifting frame and the pressure roller press and limit the core from above, and the limiting rods ensure the running state of the pressure roller.

[0009] Preferably, the driving component includes a driving motor, which is fixedly mounted on the side of another movable frame. The output shaft of the driving motor passes through the movable frame and is fixedly connected to an inner support plate at the end of the output shaft. Multiple inner support claws are fixedly connected to the side of the inner support plate at equal angles. The driving motor, together with the inner support plate and the inner support claws, fixes the film roll core, so that the driving motor drives the roll core to rotate.

[0010] Preferably, the film limiting assembly includes two sets of fixed connecting columns, which are respectively fixedly connected to the sides of two movable frames. Each of the two fixed connecting columns is fixedly connected to a limiting plate. The limiting plate has multiple mounting grooves at equal angles on its side. A limiting roller is rotatably connected inside the mounting groove. The limiting roller rotates relative to the film when the film is wound up, reducing friction between the roller and the film.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By designing a moving frame, drive motor, support roller, mounting plate, adjusting screw, limiting rod, lifting frame, pressure roller, rotating top plate, fixed connecting column, and limiting plate, one end of the core can be supported and squeezed to fix it during installation, while the other end can be internally supported and fixed. At the same time, the limiting plate provides pre-support for the core, making the installation and disassembly of the core more convenient.

[0013] By designing a limiting plate, mounting groove, and limiting roller, the film contacts the limiting roller during winding. The rotation of the limiting roller reduces friction with the film edge, ensuring the quality of the film after winding. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-4 This utility model provides a winding device for processing thermoplastic polyurethane film, including a fixed frame 1. Support legs 2 are fixedly connected to the four corners of the bottom of the fixed frame 1. Mounting base plates 3 are fixedly connected to the bottom of the support legs 2. Mounting base plates 3 have mounting holes on their top surfaces for fixing the device in a suitable position, such as a winding workbench, by bolts. An adjustment component is internally connected to the fixed frame 1. Two movable frames 6 are connected to both ends of the adjustment component. The movable frames 6 are composed of a horizontal plate, a vertical plate, and an inclined reinforcing plate. A clamping support component is installed in the middle of one side of one movable frame 6. A pressing and limiting component is fixedly connected to the top of the side of the movable frame 6. A driving component is fixedly installed on the side of the other movable frame 6. Film limiting components are fixedly connected to the sides of the two movable frames 6 that are close to each other.

[0021] Furthermore, the adjustment assembly includes a bidirectional lead screw 4, which is rotatably connected to the middle of the fixed frame 1. Two supporting horizontal shafts 5 are symmetrically fixedly connected inside the fixed frame 1. The supporting horizontal shafts 5 pass through two movable frames 6, which can slide along the supporting horizontal shafts 5. The two supporting horizontal shafts 5 are symmetrically distributed on both sides of the bidirectional lead screw 4. One end of the bidirectional lead screw 4 passes through the side wall of the fixed frame 1 and is fixedly connected to an adjusting wheel 21. The other end of the bidirectional lead screw 4 is connected to the inner wall of the fixed frame 1 through a bearing with a seat, so that the bidirectional lead screw 4 can rotate.

[0022] Furthermore, the clamping support assembly includes two support rollers 8, which are symmetrically fixedly connected to the side of a movable frame 6. A rotating top plate 14 is rotatably connected to the middle of the side of the two movable frames 6 that are close to each other. An anti-slip soft pad is fixedly connected to the surface of the rotating top plate 14 to increase the friction and provide some protection for the core. When installing the core, one end of the core is placed between the two support rollers 8 so that the outer side of the core and the bottom surface of the core are in contact to support the core. After the core is fixed, the end of the core abuts against the surface of the rotating top plate 14.

[0023] Furthermore, the pressing and limiting assembly includes a mounting plate 9, which is fixedly connected to the top side of a movable frame 6. An adjusting screw 10 is threadedly connected to the middle of the mounting plate 9, and a lifting frame 12 is rotatably connected to the bottom end of the adjusting screw 10. A pressure roller 13 is rotatably connected inside the lifting frame 12. Two limiting rods 11 are symmetrically fixedly connected to the bottom end of the mounting plate 9. The two limiting rods 11 extend through the top plate of the lifting frame 12. When pressing and fixing the end of the core, rotating the adjusting screw 10 causes the adjusting screw 10 and the mounting plate 9 to screw together, causing the adjusting screw 10 to drive the lifting frame 12 and the pressure roller 13 to move downward. During this process, the lifting frame 12 slides downward along the limiting rods 11 until the pressure roller 13 contacts and connects with the surface of the core, thus pressing and fixing the end of the core.

[0024] Furthermore, the drive assembly includes a drive motor 7, a control switch fixedly mounted on the top surface of the drive motor 7, and the drive motor 7 fixedly mounted on the side of another movable frame 6. The output shaft of the drive motor 7 passes through the movable frame 6 and an inner support plate 19 is fixedly connected to the end of the output shaft. Multiple inner support claws 20 are fixedly connected at equal angles to the side of the inner support plate 19. Soft pads are provided on the outer side of the inner support claws 20 to increase friction. When installing the core, one end of the core is put on the inner support claw 20, and the end of the core is supported and fixed by the inner support. After the fixing is completed, the drive motor 7 is started to drive the inner support plate 19 to rotate, thereby causing the inner support claws 20 to rotate and driving the core to rotate.

[0025] Furthermore, the film limiting assembly includes two sets of fixed connecting columns 15, which are respectively fixedly connected to the sides of the two movable frames 6. Each of the two fixed connecting columns 15 is fixedly connected to a limiting plate 16. The limiting plate 16 has multiple mounting grooves 17 at equal angles on its side. A limiting roller 18 is rotatably connected inside the mounting groove 17. When the film is wound up, the film is wound on the core. When winding up, the edge of the film contacts the limiting roller 18. The limiting roller 18 rotates to reduce the friction between the film and the limiting roller 18.

[0026] When this application embodiment is used:

[0027] When using this device, firstly, rotate the adjusting wheel 21 to drive the bidirectional screw 4 to rotate. The bidirectional screw 4 rotates and engages with the two moving frames 6, causing the two moving frames 6 to move away from each other. Then, pass a core through the limiting plate 16 and place one end of the core between the two supporting rollers 8, so that the outer surface of the core contacts the bottom surface of the core to support it. Rotate the adjusting screw 10 to engage with the mounting plate 9, causing the adjusting screw 10 to drive the lifting frame 12 and the pressure roller 13 to move downwards. During this process, the lifting frame 12 moves along the limiting rod 11 towards... Slide the roller down until the pressure roller 13 contacts and connects with the core surface, pressing and fixing the core end. Then rotate the adjusting wheel 21 in the opposite direction so that the two moving frames 6 move closer to each other and the inner support claw 20 moves closer to the other end of the core until the other end of the core is fitted onto the inner support claw 20. The core end is supported and fixed by the inner support method. After fixing, first fix the film end to the core surface, then start the drive motor 7 to drive the inner support plate 19 to rotate, thereby rotating the inner support claw 20 and driving the core to rotate, and then you can start winding. When disassembling, just follow the reverse steps.
