Description

Technical Field

[0001] This utility model relates to the field of thin film processing equipment, and in particular to a PEEK thin film processing equipment. Background Technology

[0002] PEEK, as a high-performance specialty engineering plastic, boasts excellent high-temperature resistance, wear resistance, high strength, and chemical stability, making it widely and indispensable in numerous high-end fields such as aerospace, electronics, and medical devices. With the rapid development of these industries, extremely stringent requirements have been placed on the quality, output, and processing efficiency of PEEK films. Developing an advanced, efficient PEEK film processing equipment capable of meeting the needs of multi-process integration has become crucial for driving progress in related industries, and is of great significance for improving product performance, reducing production costs, and expanding the application range of PEEK materials.

[0003] In existing PEEK film processing technologies, traditional methods primarily employ a step-by-step operation. In the blown film stage, a single-screw extruder is typically used with conventional molds to produce films from PEEK raw materials through a simple extrusion process. This method has limitations in terms of raw material plasticization uniformity, making it difficult to fully utilize the excellent properties of PEEK materials. In the printing process, the blown films are usually transported to specialized printing equipment, where traditional screen printing or gravure printing techniques are used for image and text printing.

[0004] Existing PEEK film processing equipment separates blown film production and printing. During the transfer of the film from the blown film equipment to the printing equipment, multiple handling, positioning, and adjustments are required. This not only consumes significant time and manpower but also easily leads to scratches, wrinkles, or even damage to the film due to improper operation, resulting in substantial material waste. Furthermore, the step-by-step operation mode, with its frequent start-ups and shutdowns, multiple parameter adjustments, and coordination between different devices, makes the entire processing flow extremely cumbersome and complex, severely impacting processing efficiency and increasing production costs. Therefore, this paper proposes a new PEEK film processing equipment to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a PEEK film processing equipment, which aims to improve the problem in the prior art where blown film and printing are carried out separately. During the process of transferring the film from the blown film equipment to the printing equipment, the film needs to be handled, positioned and adjusted multiple times, which can easily cause scratches, wrinkles or even damage to the film due to improper operation, resulting in a large amount of material waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PEEK film processing device includes a frame platform with upper and lower layers, each with a herringbone support fixedly connected inside.

An upper traction device is fixedly connected to the upper frame platform, located above the bubble stabilizer, and contains an upper traction rotating frame. A lower traction device is fixedly connected to the upper surface of the lower frame platform, with an edge straightening machine above it and a corona generator behind it. A printing machine is located below the lower traction device, and a winding machine is located behind it, with a winding traction device fixedly connected above it.

Detailed Implementation

[0030] 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.

[0031] Reference Figures 1-4This utility model provides one embodiment: a PEEK film processing equipment. PEEK film, as a high-performance special engineering plastic, boasts excellent high-temperature resistance, wear resistance, high strength, and chemical stability, making it widely and indispensable in many high-end fields such as aerospace, electronics, and medical devices. In summary, PEEK film plays a vital role in multiple industries due to its unique properties and wide range of applications. The integrated blown film machine and printing machine process is a highly efficient plastic film production method, combining the blown film and printing processes to achieve continuous and automated production from raw materials to finished products. A PEEK film processing device includes a frame platform 1, which has upper and lower layers. A herringbone support 14 is fixedly connected inside the frame platform 1. An extruder 2 is installed below the frame platform 1. The extruder 2 adopts a spiral feeding structure, which ensures uniform feeding of the PEEK raw material as it enters the extruder 2. The extruder 2 has a three-layer composite extrusion structure, and the discharge port of each layer is connected to the inlet of a die 16. This three-layer composite extrusion structure can extrude PEEK raw materials or additives with different properties in layers, greatly expanding the application range of PEEK films. One end of the extruder 2 is equipped with a die 16, and an air ring 17 is fitted outside the discharge end of the die 16. The air ring 17 can blow out uniform and stable cold air to rapidly cool the high-temperature PEEK melt extruded from the die 16, so that the film can be quickly shaped, ensuring the uniformity of film thickness and surface quality. A bubble stabilizing frame 3 is fixedly connected inside the lower frame platform 1. The bubble stabilizing frame 3 can stabilize the film bubble during the film inflation process, preventing the film bubble from shaking or deforming due to airflow fluctuations, equipment vibration, etc., and ensuring the stability of the film during the rising process. The upper surface of the upper frame platform 1 is fixed. An upper traction device 4 is fixedly connected to the film. The upper traction device 4 is used to pull the film after it has been extruded by the mold 16 and cooled and formed by the air ring 17. The upper traction device 4 can adjust the longitudinal stretch of the film by controlling the traction speed, thus affecting the longitudinal mechanical properties of the film. The upper traction device 4 is located above the bubble stabilizer 3. This layout allows the film to be pulled smoothly in a stable state. The upper traction device 4 is equipped with an upper traction rotating frame 5, which is used to drive the film to rotate and pull. Rotational traction can make the film uniformly stressed in the circumferential direction, avoiding the anisotropy of the film caused by unidirectional traction. To improve the performance consistency of the film in all directions, a lower traction device 8 is fixedly connected to the upper surface of the lower frame platform 1. The position of the lower traction device 8 corresponds to that of the upper traction device 4, and the rotation direction of the lower traction device 8 is adapted to the rotation direction of the upper traction device 4. The lower traction device 8 mainly plays an auxiliary traction role and works in conjunction with the upper traction device 4 to further control the film conveying speed and tension. An edge straightening machine 7 is set above the lower traction device 8. The edge straightening machine 7 is used to adjust the position of the film according to the edge straightening signal. The edge straightening machine 7 can monitor the edge position of the film in real time. Once a deviation is detected, it will immediately correct the deviation.The machine immediately issues an edge correction signal and adjusts the film position via the actuator to ensure the film remains in the correct position throughout subsequent processing, improving product qualification rate. A corona machine 6 is installed behind the edge correction machine 7. The corona machine 6 performs corona treatment on the surface of the passing film. Corona treatment creates a microscopic rough structure on the film surface, increasing its activity and improving adhesion to inks and coatings. After corona treatment, ink adheres better to the film surface in subsequent printing processes, resulting in clearer, more durable printed patterns that are less prone to fading or peeling, thus improving printing quality. (The text abruptly ends here.) Below the guiding device 8 is a printing machine 9, which is used to print the required graphic information on the corona-treated film surface. The printing machine 9 works in conjunction with the corona machine 6, the lower traction device 8, and other components to achieve accurate printing of the film during stable conveying. Behind the printing machine 9 is a winding machine 10, which is used to wind and collect the printed film. Above the winding machine 10 is a winding traction device 15, which contacts the film to assist the winding machine 10 in winding the film. A control box 11 is located on one side of the frame platform 1. The control box 11 is used to control... The control box 11 centrally controls the feeding speed, extrusion temperature, and extrusion ratio of each layer of the extruder 2, the air volume and air pressure of the air ring 17, the traction speed and tension of the upper traction device 4, lower traction device 8, and winding traction device 15, the corona intensity of the corona machine 6, the correction parameters of the edge straightening machine 7, and the printing parameters of the printing machine 9. By controlling these parameters, the stability of the entire PEEK film processing process is ensured. A staircase 12 is fixedly connected to the side wall of the lower frame platform 1, and a staircase 23 is fixedly connected to the upper surface of the lower frame platform 1. One end of the staircase 213 is fixedly connected to the upper... The side wall of the frame platform 1, with stairs 12 and 13, facilitates operator access to and from the frame platform 1, enabling daily inspection, maintenance, cleaning, and parameter adjustments of various equipment components. This improves the operability and ease of maintenance. This product is a blown film extrusion machine for PEEK materials, employing a top-blowing process, 3-layer composite extrusion, and an IBC internal cooling circulation mold with a spiral feeding structure. It includes an extruder, mold, air ring, bubble stabilizer, rotary traction, corona machine, edge straightening machine, lower traction, printing machine, and winding machine, achieving a one-piece process of blown film, printing, and winding, saving space and labor. This structure integrates the blown film and printing processes, reducing equipment footprint and the number of operators, lowering production costs, and increasing production efficiency. The continuous and automated production method reduces waiting time and manual intervention during production, improving efficiency, reducing waste and pollution, and avoiding waste from secondary processing and manpower waste. This is beneficial to environmental protection and sustainable development. It is highly adaptable and can be customized with different thicknesses, colors, and patterns according to customer needs to meet diverse market demands.

[0032] Working Principle: When using this equipment, PEEK material particles are fed into extruder 2. The screw inside extruder 2 rotates under the drive of a motor, heating the particles to a molten state. Because extruder 2 adopts a three-layer composite extrusion structure, three different formulations or properties of PEEK materials enter from their respective feed ports. Driven by the screw, they converge at the front end of extruder 2 and are initially compounded before entering die 16. The discharge port of each layer is connected to the feed port of die 16. The spiral feeding structure makes each layer of material more stable and uniform during the extrusion process. The molten composite PEEK material is pushed to die 16 by the screw. The material is extruded through the annular gap of die 16 to form a tubular film preform. The air ring 17 is sleeved outside the discharge end of die 16, and the cold air blown out by the air ring 17 is uniformly distributed. The air is evenly blown onto the surface of the film preform, cooling the film from the outside in, promoting rapid cooling and curing, while controlling the lateral expansion and thickness uniformity of the film. The flow rate and temperature of the cold air can be precisely adjusted according to production process requirements to adapt to the production of PEEK films with different thicknesses and performance requirements. During the film's ascent, the bubble stabilizing frame 3, fixedly connected inside the lower frame platform 1, supports and stabilizes the tubular film, preventing it from shaking, deforming, or breaking under the influence of airflow and traction, ensuring the stability and continuity of the blown film process, and guaranteeing consistent film quality. The upper traction device 4 on the upper frame platform 1, located above the bubble stabilizing frame 3, is used to pull the film after it has been extruded by the die 16 and cooled and formed by the air ring 17. The upper traction device 4 is equipped with an upper traction rotor. The rotating frame 5, through its rotational motion, ensures uniform force on the film in the circumferential direction, preventing uneven local stretching during traction and further improving film thickness uniformity and overall quality. Simultaneously, adjusting the ratio of the speed of the upper traction device 4 to the extrusion speed of the extruder 2 allows for precise control of the longitudinal stretch ratio of the film, thereby regulating its mechanical properties. The film, initially formed through the blown film stage, passes through a corona machine 6 before entering subsequent processes. The corona machine 6 uses high-voltage discharge to form a micro-rough structure on the film surface and introduces polar groups, increasing surface tension and adhesion, significantly improving the film's ink adsorption performance, ensuring the ink adheres firmly to the film surface, and improving printing quality and clarity. Due to the processes of blown film and traction... The film is prone to lateral shift. The edge straightening machine 7 on the upper surface of the lower frame platform 1 is located above the lower traction device 8. It detects the edge position of the film through sensors. When film shift is detected, the relevant mechanisms are controlled to adjust the film laterally, ensuring that the film always stays on the correct running track. This avoids problems such as printing position deviation or uneven winding caused by film shift. The lower traction device 8 is positioned corresponding to the upper traction device 4, and its rotation direction is adapted to the rotation direction of the upper traction device 4, further controlling the film's running speed and tension to ensure that the film remains stable when entering the printing press 9. The printing press 9 transfers ink to the film surface through the printing roller according to the preset pattern and text information. During the printing process, the lower traction device 8 and the printing press 9 work together.To achieve high-quality printing results, the printed film is finally wound up by a winding machine 10. A winding traction device 15, fixedly connected above the winding machine 10, contacts the film to assist in winding. The tension control system of the winding machine 10 can adjust the winding tension in real time according to the film's thickness, width, and material characteristics, ensuring that the film maintains uniform tension throughout the winding process and preventing film loosening, wrinkling, or breakage. Simultaneously, the winding machine 10 can wind the film into rolls of different diameters and lengths according to production needs, facilitating subsequent storage and transportation. The entire equipment is controlled by a control box 11 located on one side of the frame platform 1. The frame platform 1 has two layers. A first staircase 12 is fixedly connected to the side wall of the lower frame platform 1, and a second staircase 13 is fixedly connected to the upper surface of the lower frame platform 1. One end of the second staircase 13 is fixedly connected to the side wall of the upper frame platform 1, facilitating maintenance and operation by operators.
