Description

TECHNICAL FIELD

[0001] The utility model relates to the processing field of release film, especially a drying device for release film processing. BACKGROUND

[0002] In the current release film processing industry, the drying link is one of the key steps to ensure product quality and performance. However, the traditional drying device generally adopts a one-time drying mode, that is, the release film completes the entire drying process when passing through a single drying chamber. Although this drying mode can meet the basic drying needs to some extent, it has significant shortcomings.

[0003] Firstly, the one-time drying mode often fails to ensure uniform heating of all parts of the release film, resulting in unsatisfactory drying effect and even uneven drying, which affects the final quality of the product. Secondly, since the release film needs to be in contact with the environment outside the drying machine before and after drying, the temperature change may cause thermal expansion and contraction of the release film, thereby affecting its dimensional stability and mechanical properties. In particular, in high-precision release film processing, this thermal expansion and contraction effect is a key factor that restricts product quality.

[0004] Therefore, it is necessary to provide a new drying device for release film processing to solve the above technical problems. SUMMARY

[0005] To solve the above technical problems, the utility model provides a drying device for release film processing.

[0006] The drying device for release film processing provided by the utility model comprises a drying box, a conveying pipe electrostatic roller, and an extension nozzle. The drying box is divided into a first drying chamber and a second drying chamber. First and second drying fans are fixedly connected to the bottom ends of the first and second drying chambers, respectively. The output ends of the first and second drying fans are in communication with the bottoms of the corresponding first and second drying chambers. A conveying pipe is connected to the top end of the first drying chamber. One end of the conveying pipe is in communication with the input end of the second drying fan. Electrostatic rollers are rotatably connected to the inner walls of the first and second drying chambers. A release film is wound around the electrostatic rollers. A feeding hole is formed in the middle of the drying box. Extension nozzles are fixedly connected to the two sides of the drying box at the feeding hole. The two groups of extension nozzles are in communication with the first and second drying chambers, respectively.

[0007] Preferably, the temperature of the first drying chamber is lower than that of the second drying chamber. The release film enters the first drying chamber first and then enters the second drying chamber. The first drying chamber is for pre-drying, and the second drying chamber is for final drying.

[0008] Preferably, the first drying chamber and the second drying chamber are fixedly connected with an impact plate at the bottom end of the inner wall, and a molecular sieve is fixedly connected above the impact plate, and the impact plate is used for dispersing the hot air passing through the first drying fan and the second drying fan.

[0009] Preferably, the extension nozzle is designed to be inclined and used for abutting against the release film.

[0010] Preferably, the input end of the first drying fan is threadedly connected with a filter cover.

[0011] Preferably, the top end of the second drying chamber is communicated with an exhaust pipe.

[0012] Compared with the related art, the drying device for processing the release film has the following beneficial effects:

[0013] The drying efficiency and quality are improved: through the segmented drying design, the device can realize gradual and uniform drying of the release film. The combination of the pre-drying of the first drying chamber and the final drying of the second drying chamber not only improves the drying efficiency, but also ensures that each part of the release film can reach the ideal drying degree, thereby improving the product quality.

[0014] The thermal expansion and contraction effect is reduced: the extension nozzle in the device cleverly solves the problem of thermal expansion and contraction of the release film caused by temperature difference during the drying process. The preheating before entering the drying chamber and the buffering after leaving the drying chamber effectively reduce the temperature difference change between the release film and the external environment, thereby reducing the influence of the thermal expansion and contraction effect on the product quality.

[0015] The hot air circulation and purification are optimized: the introduction of the hot air circulation system not only improves the energy utilization efficiency, but also ensures the continuity and uniformity of the hot air during the drying process. At the same time, the molecular sieve and the impact plate are arranged to effectively purify and disperse the hot air, avoiding the damage that may be caused by the direct impact of the hot air on the surface of the release film, and improving the cleanliness and uniformity of the hot air.

[0016] The electrostatic adsorption effect is enhanced: the use of the electrostatic roller makes the release film closely adhere to the roller through the principle of electrostatic adsorption, effectively preventing the deviation or deformation of the release film during the drying process, and ensuring that the hot air can more effectively cover and act on the surface of the release film, thereby improving the drying efficiency.

[0017] The working environment and safety are improved: the arrangement of the filter cover effectively filters the impurities and dust in the air entering the drying chamber, maintaining the cleanliness of the drying chamber. At the same time, the introduction of the exhaust pipe timely discharges the moisture and excess heat generated during the drying process outside the device, maintaining a good ventilation and suitable working environment in the drying chamber, and improving the comfort and safety of the operators.

[0024] It should be noted that: in first drying chamber 101 and second drying chamber 102, first drying fan 201 and second drying fan 202 are configured respectively, which are responsible for sending hot air into the bottom of the drying chamber, and uniformly blowing the surface of release film through the gap between electrostatic rollers 3. In particular, the hot air generated by first drying chamber 101 is guided to the input end of second drying fan 202 through conveying pipe 2 after completing preliminary drying, realizing the recycling of hot air and improving energy utilization efficiency.

[0025] Please refer toFigures 1-2 The temperature of the first drying chamber 101 is lower than that of the second drying chamber 102, the release film enters the first drying chamber 101 first and then enters the second drying chamber 102, the first drying chamber 101 is pre-drying, the second drying chamber 102 is final drying, the inner wall bottom end of the first drying chamber 101 and the second drying chamber 102 is fixedly connected with an impact plate 5, a molecular sieve 6 is fixedly connected above the impact plate 5, the impact plate 5 is used for dispersing hot air passing through the first drying fan 201 and the second drying fan 202, the extension nozzle 4 is designed to be inclined, and is used for being attached to the release film, the input end of the first drying fan 201 is threadedly connected with a filter cover 7, and the top end of the second drying chamber 102 is communicated with an exhaust pipe 8.

[0026] It should be noted that the release film first enters the first drying chamber 101 with a lower temperature for pre-drying, removing most of the moisture, and avoiding material deformation caused by direct high-temperature contact. Subsequently, the release film enters the second drying chamber 102 with a higher temperature for final drying, ensuring complete removal of residual moisture and achieving the required drying level. This segmented drying method improves drying efficiency and effectively controls temperature changes during the drying process.

[0027] The working principle of the drying device for release film processing provided by the utility model is as follows:

[0028] The drying device for release film processing provided by the utility model is mainly based on the technologies of segmented drying, hot air circulation, electrostatic adsorption, molecular sieve 6 purification, and impact plate 5 dispersed hot air, aiming to optimize drying effect and reduce thermal expansion and contraction effect caused by temperature difference of the release film. The following is a detailed working principle description:

[0029] Segmented drying: The device divides the drying box 1 into the first drying chamber 101 and the second drying chamber 102, with different temperature settings. The release film first enters the first drying chamber 101 with a lower temperature for pre-drying, removing most of the moisture, and avoiding material deformation caused by direct high-temperature contact. Subsequently, the release film enters the second drying chamber 102 with a higher temperature for final drying, ensuring complete removal of residual moisture and achieving the required drying level. This segmented drying method improves drying efficiency and effectively controls temperature changes during the drying process.

[0030] Hot air circulation: In the first drying chamber 101 and the second drying chamber 102, the first drying fan 201 and the second drying fan 202 are respectively configured, which are responsible for sending hot air into the bottom of the drying chamber and blowing evenly on the surface of the release film through the gap between the electrostatic rollers 3. In particular, the hot air generated by the first drying chamber 101 is guided to the input end of the second drying fan 202 through the conveying pipe 2 after completing the preliminary drying, realizing the recycling of hot air and improving the energy utilization efficiency.

[0031] Electrostatic adsorption: the setting of electrostatic roller 3 utilizes the principle of electrostatic adsorption, which makes the release film closely adhere to the roller, preventing the release film from deviating or deforming during the drying process, and ensuring that the hot air can more effectively cover and act on the surface of the release film.

[0032] Molecular sieve 6 purifies and impact plate 5 disperses hot air: impact plate 5 is fixedly connected to the bottom end of the inner wall of the first drying chamber 101 and the second drying chamber 102, and molecular sieve 6 is fixedly connected above the impact plate 5. The hot air is dispersed by the impact plate 5 before blowing the release film, so that the hot air is more uniform. At the same time, the molecular sieve 6 utilizes its strong adsorption capacity to purify the impurities, dust and water molecules in the hot air, ensuring that the hot air entering the drying chamber is pure and dry. This design not only improves the uniformity and cleanliness of the hot air, but also effectively avoids the damage that may be caused by the direct impact of the hot air on the surface of the release film.

[0033] Extension nozzle 4 design: the extension nozzle 4 symmetrically arranged on both sides of the feed hole 9 opened in the middle of the drying box 1 plays a key role. For the incoming release film, the design of the extension nozzle 4 allows it to be preliminarily preheated before entering the drying chamber, reducing the thermal shock caused by sudden entry into a high-temperature environment. For the outgoing release film, the extension nozzle 4 acts as a buffer, avoiding the thermal expansion and cold contraction effect caused by its rapid contact with cold air.

[0034] Filtering and exhaust: the input end of the first drying fan 201 is threadedly connected with the filter cover 7, which effectively filters the impurities and dust in the air entering the drying chamber. The exhaust pipe 8 connected to the top end of the second drying chamber 102 is responsible for discharging the moisture and excess heat generated during the drying process outside the device, maintaining a good ventilation and suitable working environment in the drying chamber.

[0035] The above-described embodiments are merely examples of the present application and do not limit the patent scope of the present application, and any equivalent structure or equivalent process conversion made by using the contents of the present application specification and drawings, or directly or indirectly applied to other related technical fields, are also included in the patent protection scope of the present application.
