Description
Technical Field
[0001] The utility model relates to the technical field of film winding devices, in particular to a winding device for producing high-transmittance and scratch-resistant polyester films. Background Art
[0002] High-transmittance and scratch-resistant polyester film is a high-performance film material, which is widely used in electronic display screen protection, solar panels, high-end packaging materials and other fields. This type of film requires high optical transparency to ensure visual clarity or light transmission efficiency, and good wear resistance and scratch resistance to ensure durability and aesthetics in long-term use. Therefore, the design of the winding device in its production process is particularly important. In the production process of high-transmittance and scratch-resistant polyester film, the smoothness and cleanliness of the film surface directly affect the quality and performance of the final product. If the film is not wound properly, it may cause scratches, wrinkles or contamination on the film surface, thereby reducing the transparency and scratch resistance of the product. Therefore, a precise winding device needs to be designed to avoid these problems. In order to ensure the flatness of the film and avoid deformation during the winding process, the winding device must be able to accurately control the tension. Too high or uneven tension will cause the film to stretch and deform, affecting dimensional stability; too low tension may cause loose rolls and wrinkles. Especially for scratch-resistant films, any slight mechanical stress may leave marks. The edge is the part of the film that is most easily damaged. In high-speed continuous production, how to effectively wind and protect the edge of the film to avoid burrs and cracks is the key to improving the yield rate. Therefore, the winding device needs to be equipped with a sophisticated edge guide and trimming system. In order to improve production efficiency and consistency of product quality, modern polyester film production lines tend to be highly automated and intelligent. In summary, the research and development and optimization of winding devices for the production of high-transparency and scratch-resistant polyester films are based on a deep understanding of the characteristics of the film and the urgent need to improve production efficiency and ensure product quality. It aims to solve the above challenges through technological innovation and promote technological progress in the industry. Utility Model Content

DETAILED DESCRIPTION
[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0016] like Figure 1As shown, a winding device for producing high-transmittance and scratch-resistant polyester film, the winding device for producing high-transmittance and scratch-resistant polyester film specifically includes a support frame 1, a winding and feeding assembly, a tensioning and pushing assembly and a finished product collection module. The winding and feeding assembly is arranged on the leftmost side of the support frame 1, and the winding and feeding assembly includes a feeding inlet 2, a guide roller 3 and a braking electric brake component. The feeding inlet 2 is arranged on the leftmost side of the support frame 1, the guide roller 3 is arranged on one side of the feeding inlet 2, the braking electric brake component is arranged above the guide roller 3, and the tensioning and pushing assembly is arranged on one side of the guide roller 3. The tensioning and pushing assembly includes a tensioning roller 4, a driving pushing component, a pushing block 5 and a pushing groove 6. The pushing groove 6 is arranged in the support frame 4, the pushing block 5 is slidably arranged in the pushing groove 6, the pushing block 5 is connected to the driving pushing component, the tensioning roller 4 is rotatably connected to the support frame 4, a static electricity elimination component is arranged on one side of the tensioning roller 4, and the finished product collection module is arranged on the support frame 4. On one side of the frame 4, in the specific implementation, the support frame 1 has a stable structure and provides a solid support platform for the entire winding device, supports and fixes all other components to ensure that they can work normally and stably. The feed inlet 2 on the winding and feeding assembly facilitates the input of the polyester film and provides an entrance for the polyester film to enter the winding device. The guide roller 3 guides accurately and rotates flexibly, guiding the film to enter the winding device correctly to prevent it from deviating from the path. The braking electric brake component reacts quickly and brakes reliably. The film can be quickly braked when necessary to prevent it from being over-conveyed or wound. The tensioning roller 4 of the tensioning and pushing assembly effectively keeps the film tensioned to prevent it from loosening. By adjusting the tension, the flatness and stability of the film during the winding process are ensured. The driving pushing component realizes smooth pushing of the film through the cooperation of the pushing block 5 and the pushing groove 6. The pushing block 5 and the pushing groove 6 ensure the stability and accuracy of the film during the pushing process.
[0017] like Figure 1 As shown, on the basis of the above method, the outer side of the support frame 4 is further covered with a transparent protective cover 7, which has good protective effect and high transparency, protecting the operator from harm during the film winding process, and at the same time facilitating the observation of the operating status of the winding device.
[0018] like Figure 1 As shown, on the basis of the above method, the finished product collection module further includes a winding fixed frame 8, an adapter seat 9 and a winding main shaft 10. The winding fixed frame 8 is arranged on the side of the support frame, the adapter seat 9 is arranged between the winding fixed frame 8 and the support frame 1, and the winding main shaft 10 is rotatably arranged on the winding fixed frame 8. In the specific implementation, the winding fixed frame 8 of the finished product collection module has a solid structure and good stability, and provides a stable support platform for the winding main shaft 10. The adapter seat 9 is firmly connected and convenient for disassembly, connecting the winding fixed frame 8 and the support frame 1 to ensure the stable operation of the winding main shaft 10. The winding main shaft 10 winds the film into a roll, which is convenient for subsequent processing and storage.
[0019] like Figure 2As shown, on the basis of the above method, the driving and pushing component includes a fixed seat 11, a pushing cylinder 12, a coupling arm 13 and a transfer rod 14. The fixed seat 11 is arranged on the support frame 1, the pushing cylinder 12 is hinged on the fixed seat 11, the coupling arm 13 is hinged at one end of the pushing cylinder 12, and the other end of the coupling arm 13 is connected to the transfer rod 14, and the transfer rod 14 is connected to the pushing block 5. In the specific implementation, the fixed seat 11 is firmly arranged on the support frame 1, providing a solid installation foundation for the entire driving and pushing component. The pushing cylinder 12 is connected to the fixed seat 11 by an articulated manner, so that it can flexibly perform telescopic movement. One end of the coupling arm 13 is hinged on the pushing cylinder 12, and the other end is connected to the transfer rod 14. This design enables the coupling arm 13 to flexibly swing according to the telescopic movement of the cylinder. The transfer rod 14 is connected to the pushing block 5, and the swinging movement of the coupling arm 13 is converted into the linear movement of the pushing block 5, so as to achieve the smooth pushing of the film.
[0020] like Figure 3 As shown, on the basis of the above method, the brake electric brake component includes a brake electromagnetic brake door 15, an electric brake telescopic frame 16 and a brake cylinder 17. The electric brake telescopic frame 16 is arranged on the side of the support frame 1, and the brake electromagnetic brake door 15 is connected to the lower part of the electric brake telescopic frame 16. The brake cylinder 17 is arranged and connected to the back of the electromagnetic brake door 15. In the specific implementation, the brake electromagnetic brake door 15 has the characteristics of rapid response and can complete the braking action in a very short time. This enables the brake electric brake component to respond quickly when it is necessary to quickly stop the film conveying or adjust the conveying speed, ensuring the accuracy and timeliness of the operation. The setting of the electric brake telescopic frame 16 enables the position of the brake electromagnetic brake door 15 to be flexibly adjusted. The brake cylinder 17, as the power source of the brake electromagnetic brake door 15, can provide a stable and powerful thrust. This enables the brake electromagnetic brake door to apply sufficient braking force during braking to ensure that the film can stop moving quickly and smoothly.
[0021] like Figure 1 As shown, on the basis of the above method, the static electricity elimination component includes a friction winding roller 18 and an ion static electricity eliminator 19. The ion static electricity eliminator 19 is arranged on the support frame 1, and the friction winding roller 18 is rotatably arranged under the ion static electricity eliminator 9. In the specific implementation, the friction winding roller 18 of the static electricity elimination component has good contact with the film and can effectively remove static electricity. The static electricity on the surface of the film is removed by friction to prevent the influence of static electricity on the quality of the film and the winding effect. The ion static electricity eliminator 19 has a good static electricity elimination effect and does not damage the film; it generates ion flow to neutralize the static charge on the surface of the film, further improving the static electricity elimination effect.
[0022] In the specific working process of the winding device for producing the novel high-transmittance and scratch-resistant polyester film, first, the polyester film is conveyed into the winding device through the feeding inlet 2. Under the guidance of the guide roller 3, the film accurately enters the winding device to prevent it from deviating from the path. At this time, if the film conveying speed is too fast or the conveying needs to be temporarily stopped, the brake electric brake component will respond quickly. The brake electromagnetic brake door 15 is quickly closed under the push of the brake cylinder 17, and the adjustment of the electric brake telescopic frame 16 ensures that the film is applied with appropriate braking force so that it can stop or adjust the speed smoothly. Next, when the film passes through the tensioning roller 4, the tensioning roller 4 maintains the appropriate tension of the film to prevent it from slackening during the subsequent winding process. This helps to maintain the flatness and stability of the film and improve the winding quality. Subsequently, the film enters the working area of the driving push component. The push cylinder 12 starts to work, and the telescopic motion of the cylinder is converted into the linear motion of the push block 5 through the transmission of the coupling arm 13 and the transfer rod 14. The push block 5 slides in the push groove 6 to achieve smooth pushing of the film. This pushing method ensures the stability and accuracy of the film during the winding process. Finally, after being processed by the static electricity elimination component, the static electricity on the film is effectively removed. The friction winding roller 18 contacts the film and removes the static electricity on the surface by friction. At the same time, the ion static eliminator 19 generates an ion flow to neutralize the static charge on the surface of the film, further improving the static electricity elimination effect. The film after the above treatment finally reaches the finished product collection module. With the support of the winding bracket 8, the winding spindle 10 starts to rotate and the film is wound into a roll. The adapter 9 ensures that the connection between the winding bracket 8 and the support frame 1 is stable and reliable, so that the winding spindle 10 can run smoothly. During the entire winding process, the support frame 1 provides a stable support platform to ensure that all components can work normally and stably. At the same time, the transparent protective cover 7 covers the outside of the support frame 4 to protect the operator from injury during the film winding process and facilitate the observation of the operating status of the winding device. In summary, the new winding device for producing high-transmittance and scratch-resistant polyester film realizes efficient and stable winding processing of polyester film through the steps of feeding, tensioning, pushing, static elimination and winding, thereby improving production efficiency and product quality.
