Description

Technical Field

[0001] This utility model relates to the technical field of film material winding equipment, specifically to a winding device for film materials. Background Technology

[0002] In the field of film material production, the winding process directly determines the product's appearance quality (such as flatness and wrinkle rate) and production efficiency (such as unloading speed and equipment adaptability). Winding is a key process in the film material production and processing flow, its purpose being to wind continuously produced films onto a winding drum for subsequent storage, transportation, or further processing. Currently, many film winding devices on the market suffer from the following problems: Poor adaptability: The winding drum support structure of traditional winding devices is mostly a fixed design, which cannot be adjusted according to the diameter, length and other specifications of the winding drum. When different specifications of film need to be processed, the entire set of support components needs to be replaced, which is cumbersome and the equipment cost is high. Inconvenient unloading: After winding, the fully loaded film roll is quite heavy. The existing equipment lacks a special support structure. Unloading requires manual assistance or reliance on external hoisting equipment, which can easily lead to film wrinkles and damage, and poses safety hazards. Therefore, there is an urgent need for a film winding device with high adaptability, convenient unloading function and strong stability to overcome the shortcomings of existing technologies.

[0020] Combined with appendix Figures 1-3 A basic frame for a winding device for film materials includes a base plate 1 and a support 2. The base plate 1 is made of Q235 steel plate to ensure overall support strength. The support 2 is fixed to the middle of the base plate 1 by welding or bolting, and has a U-shaped structure to provide rotational support for the movable plate 3.

[0021] In a specific implementation, this utility model includes a movable winding mechanism. One side of the support 2 is rotatably connected to a movable plate 3 via a rotating shaft and bearing. The movable plate 3 is a circular steel plate, and its center is connected to the output end of the drive motor 6. Multiple sets of connecting devices 4 are installed on the movable plate 3, and the connecting devices 4 are arranged in a circular array around the center of the movable plate 3, such as 3 or 6 sets, to ensure that the winding drum is subjected to uniform force.

[0022] In a specific implementation, this utility model includes an adjustable connecting device 4, which comprises a connecting frame 401, a cylinder 402, a connecting block 403, a baffle 404, a limiting block 405, and a guide rod 406. The connecting frame 401 is a U-shaped metal frame, fixed to the movable plate 3 by bolts. The cylinder 402 is a standard SC series cylinder, fixed to the horizontal section of the connecting frame 401. The telescopic end of the cylinder 402 is connected to the connecting block 403 by bolts. An arc-shaped baffle 404 is welded to the other side of the connecting block 403. The curvature of the baffle 404 matches the inner curvature of a common winding drum, such as a radius of 50-200mm, to improve the support fit. The limiting block 405 is welded to the inner side of the connecting frame 401. A stainless steel guide rod 406 is welded to the end of the baffle 404 near the cylinder 402. The guide rod 406 passes through the gap between the limiting blocks 405 and can move linearly along the gap to prevent the baffle 404 from shifting when the cylinder 402 telescopically extends or retracts.

[0023] In its specific implementation, this utility model includes a movable support device 5, which comprises a movable plate 501, a support column 502, a support plate 503, a guide rail 504, and a slider 505. The movable plate 501 is a rectangular metal plate with four polyurethane rollers installed at its lower end to reduce noise and wear. Two linear guide rails 504 are fixed parallel to each other on the base plate 1. A slider 505 adapted to the guide rails 504 is installed at the lower end of the movable plate 501 to ensure that the movable plate 501 moves accurately along the guide rails 504. The support column 502 is a height-adjustable metal column, which is welded to the movable plate 501 by means of thread adjustment. An arc-shaped support plate 503 is welded to its top. The arc of the support plate 503 matches the arc of the outer side of the winding drum and is used to support the winding drum during unloading.

[0024] In specific implementation of this utility model, the drive motor 6 is selected from either a stepper motor or a servo motor according to the winding speed requirements, such as a power of 0.75-2.2kW, and is fixed in the cavity of the bracket 2 with bolts. The output end of the drive motor 6 is connected to the center of the movable plate 3 through a coupling, and a deep groove ball bearing is installed at the connection between the output end and the bracket 2 to reduce rotational friction and improve drive stability. A 1.5kW servo motor (model 60EMA-15CB24) is selected and fixed in the cavity of the bracket 2 with four M10 bolts; the output end is connected to the center of the movable plate 3 through a flexible coupling, and a 6206 deep groove ball bearing is installed at the connection between the output end and the bracket 2.

[0025] The working principle of this utility model: Installation of the take-up drum: According to the inner diameter of the take-up drum, start the cylinder 402. The telescopic end of the cylinder 402 pushes the connecting block 403 and the baffle 404 to move until the baffle 404 fits against the inner side of the take-up drum. The guide rod 406 moves along the gap of the limit block 405 to ensure that the position of the baffle 404 is stable, and the installation of the take-up drum is completed. Film winding: Start the drive motor 6. The output end of the drive motor 6 drives the movable plate 3 to rotate. The winding drum rotates synchronously with the movable plate 3, and the film is wound onto the winding drum. During the winding process, the guide rod 406 cooperates with the limit block 405 to prevent the baffle 404 from shifting and ensure that the winding is flat. Unloading from the take-up drum: After winding is completed, turn off the drive motor 6, push the moving plate 501, and the slider 505 moves along the guide rail 504, so that the support plate 503 moves to below the take-up drum; adjust the height of the support column 502 so that the support plate 503 fits against the outside of the take-up drum and provides stable support; start the cylinder 402 to retract the baffle 404 and disengage it from the inside of the take-up drum; push the moving plate 501 to move the take-up drum to the designated position to complete the unloading.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
