Technical Field
[0001] This utility model relates to the field of thin film blowing technology, and in particular to a PEEK thin film blowing rotation mechanism. Background Technology
[0002] In the field of modern materials processing, polyetheretherketone (PEEK) film is widely used in many high-end industries such as aerospace, electronics, and medical due to its excellent performance. The blown film process is an important way to produce PEEK film, and the rotary traction process plays a key role in the quality of the film. An efficient and stable rotary traction device can ensure that the various performance indicators of the film meet the standards during the production process and meet the strict requirements of different industries for PEEK film.
[0003] Existing PEEK film blowing and rotating mechanisms mostly employ simple gear or belt drives. Structurally, they typically involve a motor directly connected to the transmission components, which drives the traction device. Through relatively basic mechanical linkage, the film's traction and rotation are achieved.
[0004] Existing technologies struggle to ensure uniform film rotation during PEEK film blowing and traction. Due to limitations in transmission methods and control mechanisms, uneven force distribution can easily occur during rotational traction, leading to frequent folding and adhesion of the film during production. This severely impacts the film's surface quality and internal structural stability, reducing product yield and hindering production efficiency. Consequently, it fails to meet the growing market demand for high-quality PEEK films. Therefore, a PEEK film blowing and traction rotation mechanism is proposed to address these issues.

[0031] 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.
[0032] Reference Figure 1 - Figure 4This utility model provides an embodiment of a PEEK film blowing rotation mechanism, including a rotating support 1. The rotating support 1 serves as the basic frame of the entire mechanism, providing stable support and reliable fixation for other components through high-strength materials and a reasonable structural design. It can withstand various forces generated during operation, ensuring the overall stability and safety of the mechanism. A herringbone plate 8 is fixedly connected to the bottom of the rotating support 1. The herringbone plate 8 adopts an adjustable structural design, allowing for flexible adjustment of the film unfolding angle according to the actual production needs of the film. By precisely controlling the angle, it effectively eliminates uneven stress generated during film unfolding, thereby ensuring the flatness of the film and providing high-quality film material for subsequent processing steps. The bottom of the herringbone plate 8 is fixed... A support frame 10 is fixedly connected to the rotating bracket 1. The support frame 10 is made of sturdy materials, and its structural design fully considers mechanical principles. It can distribute the weight of the mechanism and the pressure generated during operation, firmly supporting the entire mechanism on the ground and preventing swaying or displacement during operation, ensuring the safety and stability of the mechanism's operation. A rotating motor 2 is installed inside the rotating bracket 1. As the core power source of the rotating mechanism, the rotating motor 2 uses efficient motor drive technology to continuously and stably output power, providing reliable power support for the entire rotating mechanism. Precise control of the motor's speed and torque enables accurate operation of the rotating mechanism. A traction bracket 22 is fixedly connected to the output end of the rotating motor 2. The traction bracket 22 is responsible for transmitting the output power of the rotating motor 2. The rotating power unit can also support other components related to film traction. Utilizing high-strength materials and a rational structural design, it maintains good rigidity and stability during power transmission, ensuring accuracy and reliability. The traction bracket 22 is fixedly connected inside the rotating bracket 1. This connection method firmly secures the traction bracket 22 within the rotating bracket 1, guaranteeing its stability during power transmission and component support. A traction motor 3 is installed on the side wall of the traction bracket 22. The traction motor 3 specifically provides power for the film traction process. By precisely controlling the motor's speed and traction force, it can stably traction the film according to the production process requirements, ensuring uniform tension of the film during traction and preventing overstretching or... In cases of insufficient thickness, a flattening roller 5 is rotatably connected to the outer wall of the rotating bracket 1. The surface of the flattening roller 5 is specially treated, possessing excellent smoothness and wear resistance. As the film passes through, its own rotation effectively flattens the film, eliminating wrinkles and unevenness on the film surface and improving the surface quality of the film. A bridging roller 7 is rotatably connected to the top of the traction bracket 22. The bridging roller 7 plays an auxiliary transition role in the film transport process, enabling the film to smoothly transition from one transport component to another, reducing friction and resistance during film transport, and ensuring smooth film transport. A support roller 6 is provided on the top of the bridging roller 7. The support roller 6 is made of high-strength material and can withstand the weight of the film, effectively supporting the film during transport.To prevent the film from sagging under its own weight and ensure that the film maintains its good shape during transportation, a rotating component is installed inside the rotating bracket 1;
[0033] The rotating component includes a planetary gear 4, which is manufactured using a precision process. Through the meshing transmission between multiple gears, it can achieve stable and precise rotational motion. Compared with traditional transmission methods, the meshing transmission of the planetary gear 4 has higher transmission efficiency and stability, effectively reducing energy loss and vibration during transmission, and ensuring the smoothness and reliability of the rotating mechanism. The top of the planetary gear 4 is fixedly connected to the inside of the rotating bracket 1, and the bottom is fixedly connected to the top of the traction bracket 22. This connection method can effectively connect the rotating bracket 1 and the traction bracket 22. Through the transmission of the planetary gear 4, the relative rotation between the two is achieved. The rotating bracket 1 is equipped with a traction component inside.
[0034] Reference Figure 1 - Figure 4The traction assembly includes a traction roller 11, which is made of high-strength and wear-resistant material. Its surface is specially treated to increase friction with the film. Stable rotation is achieved through a precise transmission system, providing continuous and stable traction force during rotation. This ensures the PEEK film advances in the rotating mechanism at a set speed and tension, effectively preventing slippage or jamming during transport. The traction roller 11 is rotatably connected inside the rotating bracket 1. This connection method ensures the stability and flexibility of the traction roller 11 during rotation, allowing it to maintain smooth rotation while bearing the film's traction force. An air-blowing roller 12 is fixedly connected inside the rotating bracket 1. The surface of the air-blowing roller 12 has uniformly distributed air holes. The airflow channel of the unit is connected to an external air source, which can blow out a uniform and stable airflow during operation, forming an air film between the film and other components. This greatly reduces the friction of the film during transmission and effectively prevents the film from being electrostatically attracted or stuck to other components due to friction, ensuring smooth film transmission. An air-blowing roller 13 is fixedly connected inside the rotating bracket 1. The air-blowing roller 13 has a similar structure and working principle to the air-blowing roller 12. Through reasonable layout and coordinated work, the two form a more comprehensive air film protection along the film transmission path, further reducing frictional resistance during film transmission, reducing surface damage and quality defects caused by friction, and effectively improving the production quality of the film. The support frame 10 is threadedly connected to a lead screw 9, which uses high-strength steel. The precision thread design provides excellent transmission accuracy and self-locking performance. During rotation, it can precisely adjust the position of related components according to actual production requirements such as film bubble size and film thickness. Through fine position adjustments, it achieves precise control of the film production process. One end of the lead screw 9 is fixedly connected to a handwheel 14. The handwheel 14 has a large operating area and a comfortable grip, allowing operators to easily rotate the lead screw 9 manually. When fine adjustments are required, operators can achieve precise control through the handwheel 14 to meet the adjustment needs of different production processes for component positions. A sliding rod 18 is slidably connected inside the support frame 10. The sliding rod 18 uses a linear bearing to cooperate with the support frame 10, ensuring smooth sliding and low friction. When wheel 14 rotates the lead screw 9, the sliding rod 18 can slide smoothly along the guide rail inside the support frame 10, precisely changing its position according to the rotation of the lead screw 9, thereby adjusting the position of related components. One end of the sliding rod 18 is rotatably connected to an adjusting wheel 19, which uses a low-friction bearing design and can rotate flexibly. This not only helps the sliding rod 18 maintain stability during sliding and reduces wobbling, but also allows for flexible angle adjustment based on the film's transmission state when in contact with components such as the film, adapting to different working conditions and ensuring the stability of film transmission. One end of the sliding rod 18 is fixedly connected to a baffle 16, which is made of a sturdy material and has a certain rigidity and strength. During film blowing, the baffle effectively blocks and guides the film bubble.To limit the swaying amplitude of the membrane bubble and prevent excessive swaying from affecting the film forming quality, ensuring stable film production, a rotating guide roller 17 is rotatably connected inside the baffle 16. The rotating guide roller 17 has a smooth surface and rotates flexibly, effectively reducing friction between the film and the baffle 16 when they come into contact, preventing scratches or damage to the film surface and ensuring the film's surface quality. A rotary bearing 21 is installed inside the traction bracket 22. The rotary bearing 21 uses a high-precision ball or roller design, featuring low friction and high load-bearing capacity, effectively supporting the weight of the traction bracket 22 and the load generated during operation. This ensures the traction bracket 22 remains stable during rotation, reducing vibration and noise, and guaranteeing the smoothness and reliability of the rotation. A rotary table mechanism 15 is fixedly connected to the top of the traction bracket 22. The rotating platform 15 adopts a high-strength structural design, possessing excellent rigidity and stability. It provides a stable mounting platform for other components and, during rotation, drives the components mounted on it to work collaboratively, ensuring coordinated action between all components and meeting the process requirements of film production. A wind pump 20 is installed on the side wall of the rotating platform 15. The wind pump 20 uses a high-performance compressed air generator, capable of producing a stable and high-pressure airflow. This serves as the air source for components requiring airflow assistance, such as the first air-blowing roller 12 and the second air-blowing roller 13, providing sufficient and stable airflow to ensure their normal operation. One side of the wind pump 20 is fixedly connected to the outer wall of the traction bracket 22. This installation method ensures a tight connection between the wind pump 20 and the traction bracket 22, guaranteeing stable operation of the wind pump 20 without affecting the overall structure and motion performance of the traction bracket 22.
[0035] Working principle: Rotary motor 2 starts, its output driving traction bracket 22, which is fixed inside the rotating bracket 1. Simultaneously, traction motor 3 on its side wall provides power for the traction action. Planetary gear 4 in the rotating mechanism has its top fixed inside the rotating bracket 1 and its bottom fixed to the top of the traction bracket 22. Utilizing the meshing transmission of planetary gear 4, the main gear drives the auxiliary gear, which in turn drives the mother-child and molecule gears in the opposite direction. This ensures the rotating mechanism is vertically mounted at the center of the support frame 10, concentric with the rotary bearing 21, achieving stable circumferential rotation. The traction roller 11, driven by traction motor 3, rotates within the rotating bracket 1, thus tractioning the PEEK film. The bottom of the herringbone plate 8 is fixed on the support frame 10. Its angle adjustment part consists of positive and negative lead screws 9, nuts, sprockets, chains, and handwheels 14. The upper end is below the center point of the traction roller 11, and the lower end is on the support frame 10. Rotating the handwheel 14 rotates the lead screw 9, and the angle of the herringbone plate 8 is adjusted as a whole through single-point linkage. This works with the traction roller 11 to ensure the flatness of the film and solve the problems of film deviation and shaking. According to the size of the film bubble, rotating the adjustment handwheel 14 drives the lead screw 9 to make the sliding rod 18 slide within the support frame 10, which drives the baffle 16 to move. Adjusting the position of the side auxiliary baffle 16 causes the guide roller 17 to rotate within the baffle 16, which helps stabilize the film bubble and reduces film surface friction. The side wall air pump 20 of the rotary table mechanism 15 supplies air to the first air blowing roller 12 and the second air blowing roller 13, blowing air at the molecular gear to reduce the friction of the film crossing. The flattening roller 5, the crossing roller 7, and the support roller 6 work together to prevent the film from folding or sticking, avoid excessive lateral offset, ensure smooth transmission of the film during the blowing and rotating traction process, and improve the film production quality.
