[0002] PET release film, also known as PET silicone film, is made of PET material. It has excellent adsorption and adhesion properties and is widely used in packaging, printing, pad printing and other industries. During production and processing, coating equipment is needed to coat the surface of the PET film with various functional materials. Different coating materials can give PET release film different properties to meet the needs of various application scenarios.

[0003] In the field of PET release film coating equipment, existing coating devices use components such as scrapers to coat the film and then use hot air to dry it, thereby curing the coating layer. However, in actual use, the wind force generated by air circulation may affect the coating layer, making it impossible to achieve uniform curing and a smooth surface. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Please see Figures 1 to 4This is the first embodiment of the present invention. This embodiment provides a PET release film coating device with rapid curing function, including: a coating device body 1, a transfer cavity 2 fixedly installed at one end of the coating device body 1, a control terminal 4 embedded on one side of the transfer cavity 2, a curing cavity 3 fixedly installed at the front end of the transfer cavity 2, and a curing mechanism 5 provided inside the curing cavity 3.

[0031] The curing mechanism 5 includes a support frame 501, which is fixedly installed inside the curing chamber 3. An ultraviolet lamp 502 is embedded at the top of the support frame 501. Mounting frames 503 are fixedly installed on both sides of the upper part of the support frame 501. A reflector 504 is embedded at the bottom of the mounting frame 503.

[0032] Specifically, a ventilation shell 505 is fixedly installed at the top of the support frame 501, and filter screens 506 are embedded at both ends of the ventilation shell 505.

[0033] Furthermore, the ventilation housing 505 allows air to circulate, which helps to dissipate heat from the ultraviolet lamp 502. The filter screen 506 filters the circulating air to prevent dust and impurities from adsorbing onto the ultraviolet lamp 502 and affecting heat dissipation.

[0034] Specifically, a ventilation fan 507 is embedded on one side of the outer wall of the filter 506, and a cooling plate 508 is embedded on the other side of the outer wall of the filter 506.

[0035] Furthermore, the filter 506 on one side is fitted with a ventilation fan 507, which can further improve the gas flow rate. At the same time, the circulating gas is cooled by the cooling chip 508. The cold end of the cooling chip 508 faces the ventilation shell 505, and the hot end faces the outside to avoid mutual interference in heat dissipation.

[0036] Specifically, the coating equipment body 1 is connected to the curing chamber 3 through the transfer chamber 2, and the curing chamber 3 is detachably connected to the support frame 501 by bolts.

[0037] Furthermore, after the release film is coated, it enters the curing chamber 3 directly through the transfer chamber 2 for curing, thus avoiding the adsorption of dust and other contaminants on the outside.

[0038] In use, the coating equipment body 1 consists of a control terminal 4, a power system, a coating system, etc. This is existing technology and will not be described in detail here. After the coating equipment body 1 is coated, it is wound up and unwound by the assembled external winding mechanism, allowing the release film to enter the curing chamber 3 through the transfer chamber 2 and pass through the support frame 501. The ultraviolet lamp 502 can accelerate the curing. At the same time, the arc-shaped reflector 504 embedded in the mounting frame 503 improves the light concentration. In addition, the ventilation shell 505 and the filter screen 506 form an air circulation channel. With the cooperation of the ventilation fan 507 and the cooling plate 508, the air circulation can be improved, which can heat up the ultraviolet lamp 502.

[0039] In summary, when coating the material, a photosensitive agent is added. A high-energy ultraviolet lamp 502 is used to irradiate the surface of the release film coated with the photosensitive agent, causing the photosensitive agent to rapidly initiate a reaction and trigger the curing process. When the release film passes through the ultraviolet lamp 502, some light directly irradiates the material, while the other part is reflected onto the material through the reflector 504. The material absorbs the ultraviolet energy, causing rapid cross-linking and curing. Simultaneously, wind-driven curing is avoided, preventing uneven curing or an uneven surface. Furthermore, the ventilation housing 505 and the ventilation fan 507 work together to dissipate the large amount of heat generated during the operation of the ultraviolet light source.

[0040] Example 2

[0041] Please see Figure 2 , Figure 3 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for a PET release film coating equipment with rapid curing function.

[0042] Specifically, a lower pressure roller 6 is rotatably connected to one side of the support frame 501 inside the curing chamber 3, and an abutment mechanism 7 is provided at the front end of the support frame 501.

[0043] Furthermore, the release film is pressed against the lower roller 6, thereby creating a tensile force that allows it to fully unfold.

[0044] Specifically, the abutment mechanism 7 includes a through groove 701, which is opened at the front end of the support frame 501. A sliding block 702 is slidably connected inside the through groove 701, and a connecting frame 703 is fixedly installed at one end of the sliding block 702 that protrudes from the through groove 701.

[0045] Furthermore, the through groove 701 can limit the sliding block 702, thereby maintaining the stability of the connecting frame 703 during sliding and preventing deviation.

[0046] Specifically, a spring 704 is fixedly installed at one end of the sliding block 702 inside the through groove 701, and an abutment roller 705 is rotatably connected between the two ends of the connecting frame 703.

[0047] Furthermore, through the elastic extension and contraction of the spring 704, and the cooperation of the contact roller 705 and the lower pressure roller 6, tension is generated during the release film conveying process, and the film is stretched adaptively to avoid loosening.

[0048] Specifically, a connection hole 706 is provided on one side of the through groove 701 at the front end of the support frame 501. A slide rod 707 is inserted into the connection hole 706, and a rubber pad 708 is fixedly installed at one end of the slide rod 707.

[0049] Furthermore, the slide bar 707 slides along the connecting hole 706 and forms a piston motion with the rubber pad 708. The support frame 501 has small micro-holes corresponding to the connecting hole 706 to facilitate air circulation, thereby improving the stability of the force displacement of the connecting frame 703 and the contact roller 705.

[0050] In use, the release film can be unfolded by the lower pressure roller 6 and the contact roller 705. With the help of the spring 704 inside the through groove 701, the sliding block 702 and the connecting frame 703 elastically contact each other when subjected to the tension of the release film, thereby preventing the release film from becoming loose during the delivery process. At the same time, when the slide rod 707 slides along the connecting hole 706, the rubber pad 708 improves the sealing performance, thereby forming a piston movement to further improve stability.

[0051] In summary, the elastic push of the spring 704 causes the contact roller 705 to rotate and contact the release film. In conjunction with the lower pressure roller 6, the release film can be unfolded and elastically contacted when it becomes loose, thus preventing bending during the conveying process and avoiding wrinkles during curing.
