Technical Field

[0001] This utility model relates to the field of film roll production, specifically a guide structure for film roll winding. Background Technology

[0002] Film rolls are flexible industrial materials made by winding plastic, metal, or composite materials into rolls. They are widely used in packaging, construction, electronics, and agriculture. The base materials include polyethylene (PE), polypropylene (PP), polyester (PET), and aluminum foil, and are processed through blow molding, casting, or coating processes. The thickness is typically between 0.01 and 0.5 millimeters. The finished products possess properties such as lightweight, moisture resistance, heat insulation, and corrosion resistance. Examples include composite films for food packaging, waterproof building membranes, and photovoltaic backsheet films. After production, film rolls require a winding device for rewinding.

[0003] For example, patent application CN 206985257 U discloses a coil winding device for automatically winding up remaining stamped coils. The coil winding device includes a guide frame and a winding device; the guide frame is positioned in the feeding direction of the winding device and includes a support and guide rollers mounted on the support; the winding device includes a winding roller mounted on a frame and a drive motor, the winding roller being drively connected to the drive motor, and a baffle plate with a locking lever at its end. This technical solution's coil winding device can automatically wind up the remaining stamped coils, thereby improving the stamping and unloading efficiency of the coils and reducing manual labor.

[0004] However, the above-mentioned technology does not have a guiding mechanism in the roll winding device, which results in the film roll being relatively loose and messy when it is wound on the winding roller; therefore, the market urgently needs to develop a guiding structure for film roll winding to help people solve the existing problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a film roll winding guide structure, including a support base plate 1, a vertical support plate 101 fixedly connected to one side of the upper end of the support base plate 1, a limiting support tube 102 fixedly connected to the upper end of one side of the vertical support plate 101, a rotating shaft 2 rotatably connected inside the limiting support tube 102, a winding roller 202 extending out of the limiting support tube 102 from one side of the rotating shaft 2, and a connecting key 201 fixedly connected to both ends of the front end of the rotating shaft 2 and to one side of the limiting support tube 102. 02 has keyways 203 at both the front and rear ends. After the rotating shaft 2 is inserted into the take-up roller 202, the connecting key 201 slides into the keyway 203. A second limiting plate 204 is connected to one side of the rotating shaft 2. The second limiting plate 204 is fixedly connected to the rotating shaft 2 by bolts 205. The rotating shaft 2 drives the take-up roller 202 to rotate and take up the film roll. After the take-up is completed, the second limiting plate 204 is separated by removing the bolts 205, and the take-up roller 202 with the film roll can be pulled out from one side.

[0024] Please see Figure 2 A drive device 3 is fixedly connected to the side of the vertical support plate 101 away from the limiting support tube 102. A motor 301 is fixedly installed inside the drive device 3. A section of the rotating shaft 2 extends into the drive device 3 and is connected to the output shaft of the motor 301 through a coupling. The motor 301 drives the rotating shaft 2 to rotate, thereby causing the rotating shaft 2 to drive the take-up roller 202 to rotate.

[0025] Please see Figure 2 and Figure 3A first limiting plate 103 is fixedly connected to one side of the outer wall of the limiting support tube 102. A limiting ring 104 is fixedly connected to one side of the middle part of the outer wall of the limiting support tube 102. A rotating ring 4 is rotatably connected to the outer wall of the limiting support tube 102 between the first limiting plate 103 and the limiting ring 104. A rotating plate 401 is fixedly connected to the front end of the rotating ring 4. The front end of the rotating plate 401 extends beyond the front end of the first limiting plate 103 and is fixedly connected to a C-shaped support frame 403 on one side. The rotating plate 401 and one side end face of the first limiting plate 103 are fixedly connected by multiple screws 402. The two sides of the support roller 5 are respectively connected to the two side end faces inside the C-shaped support frame 403 through damping shafts 501. The lower inner end of the C-shaped support frame 403 is rotatably connected to the support roller 5, and the upper inner end of the C-shaped support frame 403 is movably connected to a C-shaped support frame 403. The lifting frame 6 has a pressure roller 602 rotatably connected to its inner side. An electro-hydraulic rod 404 is fixedly connected to the middle of the upper end of the C-shaped support frame 403. The telescopic end of the lower end of the electro-hydraulic rod 404 passes through the C-shaped support frame 403 and is fixedly connected to the middle of the upper end of the C-shaped lifting frame 6. When the film roll is wound up, it first passes between the support roller 5 and the pressure roller 602. The electro-hydraulic rod 404 drives the C-shaped lifting frame 6 to descend, so that the support roller 5 and the pressure roller 602 clamp the film roll. Then, when the film roll is wound up, it guides the film roll to be wound onto the winding roller 202. When the film roll is wound up, it drives the support roller 5 to rotate. The damping shaft 501 provides damping force, so that the winding roller 202 pulls the film roll to tighten it when winding up, ensuring that the film roll is neat and taut on the winding roller 202.

[0026] Please see Figure 3 The upper ends of the C-type support frame 403 are fixedly connected to guide tubes 405 on both sides, and the upper ends of the C-type lifting frame 6 are fixedly connected to guide rods 601 on both sides. The upper ends of the two guide rods 601 pass through the interior of the two guide tubes 405 respectively. When the C-type lifting frame 6 is raised or lowered, it is guided by sliding along the guide tubes 405 through the guide rods 601 to ensure the stability of the C-type lifting frame 6 during raising and lowering.

[0027] Working Principle: In use, the end of the film roll is first passed through the gap between the support roller 5 and the pressure roller 602. The electro-hydraulic lever 404 is activated to push the C-shaped lifting frame 6 downwards, causing the pressure roller 602 to engage with the support roller 5 to clamp the film roll. Then, the motor 301 in the drive unit 3 is activated, driving the take-up roller 202 to rotate via the rotating shaft 2 for winding. During winding, the film roll drives the support roller 5 to rotate. The damping force generated by the damping shaft 501 keeps the film taut. Simultaneously, the screws 402 are removed, allowing the rotating plate 401 to rotate around the limiting support tube 102. The screws 402 are then re-secured during rotation, allowing the C-shaped support frame 403 to adjust its angle according to the film's winding position, providing guidance in different directions. The cooperation of the guide rod 601 and the guide tube 405 ensures smooth lifting and lowering of the pressure roller 602, ultimately resulting in the film roll being neatly and tightly wound onto the take-up roller 202. After winding is complete, the second limiting plate 204 can be removed by unscrewing bolt 205, and the fully wound winding roller 202 can be pulled out from the rotating shaft 2.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
