Description

Technical Field

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

[0002] In the production of heating films, winding is a crucial downstream process, its quality directly affecting the product's storage, transportation, and performance. However, existing heating film winding devices generally suffer from the following shortcomings: First, heating films often carry significant residual heat after forming. Direct winding can easily lead to excessively high interlayer temperatures, causing the film to soften, stick together, or even displace or damage internal conductive lines, severely impacting product quality and yield. Existing equipment lacks effective online active cooling methods. Second, the control precision of film tension during winding is insufficient, easily causing uneven tension leading to film stretching deformation, wrinkling, or breakage. Third, the fixed spacing of traditional winding shafts makes it difficult to quickly adapt to different specifications of cores, and core replacement is cumbersome and time-consuming, affecting production efficiency. Furthermore, the lack of effective support for the film roll during winding poses safety hazards and easily damages the film roll edges during roll changes. Therefore, there is an urgent need for a winding device that features efficient cooling, precise tension control, convenient roll changes, and effective protection of the film material to solve these problems.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 4 A winding device for producing heating film includes a workbench 1, a control panel 2 on the workbench 1, a conveyor belt 3 on the upper end of the workbench 1, a cooling component on one side of the conveyor belt 3, and a winding component on the side of the workbench 1 near the cooling component.

[0022] The cooling assembly includes guide rollers 4, cooling rollers 5, and chillers 6. A cooling roller 5 is installed on one side of the upper conveyor belt 3 of the workbench 1. The cooling roller 5 is hollow. Guide rollers 4 are installed on both sides of the cooling roller 5. The guide rollers 4 are rotatably connected to the workbench 1 through transmission rods 402. A first motor 401 is installed on the outside of the workbench 1. The first motor 401 is used to drive the transmission rods 402. Cavities are provided inside both sides of the workbench 1. Openings are provided in opposite cavities. A chiller 6 is mounted on the cavity of the workbench 1 below the cooling roller 5. The chiller 6 is fixedly connected to the lower end of water pipes 601 on both sides. The upper end of water pipes 601 is rotatably connected to the cooling roller 5 through a rotary joint 603. A water pump 602 is installed in the middle of water pipes 601.

[0023] Through the above technical solution, the conveyor belt 3 is horizontally installed on the upper end of the workbench 1. A built-in drive mechanism continuously transports the heated film from the previous process to the cooling assembly at a set speed, providing a continuous supply of film material for subsequent cooling and winding. The cooling roller 5 has a hollow structure and achieves cooling through a water circulation system. The chiller 6 generates low-temperature cooling water, which is driven by the water pump 602 to flow along the water pipe 601. Through the rotary joint 603 (the stationary end connects to the water pipe 601, and the rotating end connects to the shaft end of the cooling roller 5), the cooling water enters the interior of the cooling roller 5 while it is rotating, absorbs heat from the film material, and then flows back to the chiller 6 for further cooling, forming a closed-loop circulation. Heat exchange reduces the temperature of the heated film in contact with the roller. The guide rollers 4 on both sides of the cooling roller 5 are driven to rotate by the first motor 401 and installed on the workbench 1 through the transmission rod 402. They guide the film material to adhere to the surface of the cooling roller 5 along a preset path, ensuring sufficient contact area to improve cooling efficiency, while also assisting in the transport of the film material and maintaining stable tension. Control panel 2 integrates the control functions of various motors, chiller 6, and water pump 602, enabling equipment start-up and shutdown, parameter adjustment, and operation monitoring, ensuring that all components work together.

[0024] This utility model provides a technical solution: the winding assembly includes a first support plate 7 and a second support plate 9. The first support plate 7 and the second support plate 9 are arranged opposite each other on the side of the workbench 1 near the cooling assembly. A first mounting joint 8 is provided on the upper inner side of the first support plate 7. The first mounting joint 8 is rotatably connected to the first support plate 7 through a first bearing 801. A second motor 802 is provided on the upper outer side of the first support plate 7. The second motor 802 is used to drive the first mounting joint 8 to rotate.

[0025] The bottom of the second support plate 9 is fixedly connected to the base plate 11. The bottom of the base plate 11 is provided with a slide rail 12. The second support plate 9 is slidably connected to the workbench 1 through the slide rail 12. The upper inner side of the second support plate 9 is provided with a second mounting joint 10. The second mounting joint 10 is rotatably connected to the second support plate 9 through a second bearing 1001. The upper outer side of the second support plate 9 is provided with a third motor 1002. The third motor 1002 is used to drive the second mounting joint 10 to rotate.

[0026] A third support plate 14 is provided between the first support plate 7 and the second support plate 9 on the workbench 1. A first cylinder 13 is provided on the side of the third support plate 14 near the second support plate 9. One end of the first cylinder 13 is fixedly connected to one side of the third support plate 14, and the other end is fixedly connected to the lower end of the second support plate 9.

[0027] Through the above technical solution, the first support plate 7 and the second support plate 9 are arranged opposite to each other on the side of the workbench 1 near the cooling component, forming a winding support frame. The first support plate 7 is fixed on the workbench 1, and the bottom of the second support plate 9 is slidably connected to the slide rail 12 on the workbench 1 through the base plate 11, and can move horizontally along the slide rail 12. The first mounting joint 8 and the second mounting joint 10 are respectively installed on the upper inner side of the two support plates through the first bearing 801 and the second bearing 1001. The bearings reduce the friction when the mounting joints rotate to ensure stability. The second motor 802 on the outside of the first support plate 7 and the third motor 1002 on the outside of the second support plate 9 drive the corresponding mounting joints to rotate. The two ends of the core are engaged between the two mounting joints and rotate synchronously with them. The third support plate 14 between the two support plates on the workbench 1 pushes the second support plate 9 to slide along the slide rail 12 through the extension and retraction of the cylinder, adjusting the distance between the two mounting joints to adapt to cores of different lengths, facilitating installation and replacement.

[0028] This utility model provides a technical solution: a support frame 15 is also provided between the first support plate 7 and the second support plate 9 on the workbench 1. The support frame 15 is provided with a second cylinder 16 at each of the four corners of the top. A support seat 17 is provided above the support frame 15. The support seat 17 is movably connected to the support frame 15 through the second cylinder 16. The support seat 17 is a support seat with a concave arc shape at the top.

[0029] Through the above technical solution, the support frame 15 between the first support plate 7 and the second support plate 9 on the workbench 1 provides a fixed foundation for the support structure. The second cylinders 16 at the four corners of its top are symmetrically distributed, which not only ensures the force balance when the support seat 17 is raised and lowered, but also realizes the vertical displacement adjustment of the support seat 17 through the extension and retraction of the cylinders. The support seat 17 is connected to the top of the second cylinder 16. Its top is designed as an arc-shaped concave shape, which is adapted to the circular outer surface of the film roll after winding. This can increase the contact area with the film roll and avoid deformation or slippage caused by uneven force on the edge of the film roll during support. During the winding process, the second cylinder 16 is in a retracted state, and the support seat 17 is in a low position, which does not affect the rotation of the film roll. When the winding is completed and a replacement roll is needed, the second cylinder 16 extends, pushing the support seat 17 to rise to contact the bottom of the film roll, and steadily supporting the film roll, so that it remains stable during the process of separating from the first mounting joint 8 and the second mounting joint 10. This facilitates the removal of the old roll manually or mechanically, and prevents the film roll from falling and being damaged due to its own weight. After the new core is installed, the second cylinder 16 retracts, driving the support seat 17 to descend and reset, without interfering with subsequent winding.

[0030] The working principle of this utility model is as follows:

[0031] During operation, the operator starts the equipment via control panel 2 and sets parameters such as conveyor belt speed 3, cooling water temperature, and winding speed. All components work in tandem. Conveyor belt 3 continuously transports the heating film from the previous process to the cooling assembly. The first motor 401 drives the guide roller 4 to rotate, guiding the film material to adhere to the surface of the cooling roller 5 along a preset path. The film material can be set to a "V" path, meaning the film material is inclined upwards from one guide roller 4, then downwards across the lower half of the arc-shaped surface of the cooling roller 5, and then inclined upwards again to the other guide roller 4, forming a "V" shaped path. The film material follows a "W" shaped path, where it first tilts downwards from one guide roller 4, then curves upwards around the upper half of the cooling roller 5, and then tilts upwards again to be conveyed to the other guide roller 4. The cooling roller 5 is driven to rotate by the friction between the film material and the roller surface; thus, the cooling roller 5 is the driven roller, and its rotational speed is determined by the film material conveying speed. This ensures sufficient contact between the film material and the surface of the cooling roller 5 to improve heat exchange efficiency, while avoiding film stretching or slippage caused by the active drive of the cooling roller 5, ensuring the film material completes the cooling process under stable tension. Simultaneously, a chiller 6 prepares low-temperature cooling water, which is driven by a water pump 602 to flow along a water pipe 601 and enters the hollow cavity of the cooling roller 5 through a rotary joint 603. After absorbing heat from the film material, the water flows back to the chiller 6 for cooling, forming a closed-loop cycle. This allows the heated film to cool rapidly during contact with the cooling roller 5, preventing subsequent winding adhesion.

[0032] After cooling, the membrane material is guided to the winding assembly. The two ends of the roll core are engaged between the first mounting joint 8 and the second mounting joint 10. The first cylinder 13 pushes the second support plate 9 to slide along the slide rail 12, adjusting the distance between the two joints to match the roll core specifications. The second motor 802 and the third motor 1002 drive the mounting joints to rotate synchronously, driving the roll core to rotate at a speed matching the membrane material conveying speed. With the help of bearings, friction is reduced, and the membrane material is smoothly wound up.

[0033] During the winding process, the second cylinder 16 on the support frame 15 is in a retracted state, and the support seat 17 is in a low position, not interfering with the rotation of the film roll. When winding is completed and a roll change is required, the second cylinder 16 extends, pushing the support seat 17, which has a concave top arc, to rise and fit against and support the bottom of the film roll. The first cylinder 13 retracts, causing the second support plate 9 to retract, and the film roll is disengaged from the installation joint. The old roll is safely removed under the support of the support seat 17. Subsequently, after the new core is installed, the first cylinder 13 pushes the second support plate 9 to reset, and the second cylinder 16 retracts, causing the support seat 17 to descend. The equipment resumes operation and begins the next round of winding.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
