Description

Technical Field

[0001] This utility model relates to the field of PET optical film processing technology, specifically a curing device for PET optical film coatings. Background Technology

[0002] PET-type optical films refer to optical-grade films made primarily of polyethylene terephthalate (PET). These films are widely used in numerous fields due to their excellent physical properties, chemical stability, and optical transparency.

[0003] Curing equipment for PET optical film coatings is mainly used to ensure that the coating material can be cured uniformly and efficiently, thereby giving the film specific functions such as scratch resistance, anti-glare, and anti-reflection. After the coating is applied, it needs to be cured. However, the existing curing equipment has a relatively fixed curing height when the film enters and exits. Different adhesives have different coating thicknesses. Therefore, such fixed height treatment can easily cause incomplete curing of the adhesive inside. Moreover, if wrinkles appear in the film during curing, it can easily affect the subsequent use effect. Therefore, we propose a curing equipment for PET optical film coatings. Utility Model Content

[0017] 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.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a curing device for PET type optical thin film coating, including a fixed frame 1 and an auxiliary support mechanism 7. The bottom of the fixed frame 1 is fixedly installed with a mounting bracket 2, and a fixing bracket 5 is fixedly installed on the fixed frame 1. A top fixing mechanism 3 is inserted into the top of the fixed frame 1. Multiple sets of UV lamps 4 are fixedly installed on the top of the inner wall of the top fixing mechanism 3. An auxiliary support mechanism 7 for film tensioning is provided inside the fixed frame 1. A height adjustment mechanism 6 for adjusting the height of the film is provided on the fixing bracket 5.

[0019] The UV lamp 4 is fixedly installed inside the top fixing mechanism 3, which can be removed from the fixing frame 1. This makes it easy to replace and maintain the UV lamp 4 after it ages. The auxiliary support mechanism 7 ensures that the film remains taut during curing and does not wrinkle. The height adjustment mechanism 6 can adjust the height of the auxiliary support mechanism 7. This design allows thicker adhesive to approach the UV lamp 4, ensuring that the adhesive cures more fully and completely.

[0020] Please see Figure 1 , Figure 2 and Figure 3The auxiliary support mechanism 7 includes a limiting sleeve 12, a second telescopic rod 13, a first gasket 14, a spring 15, a connecting shaft 16, and a limiting roller 17. The limiting sleeve 12 is fixedly installed on the top of the first telescopic rod 9. The second telescopic rod 13 is slidably connected inside the limiting sleeve 12. The first gasket 14 is fixedly connected to the outside of both the limiting sleeve 12 and the second telescopic rod 13. Springs 15 are fixedly connected to the outside of the two sets of first gaskets 14 and located outside the limiting sleeve 12. The connecting shaft 16 is fixedly installed on the top of the first gasket 14. The limiting roller 17 is rotatably connected to the outside of the connecting shaft 16.

[0021] The film to be cured passes through the top of the limiting roller 17, and the spring 15 thereafter provides a squeezing force, causing the first telescopic rod 9 to move upward along the inside of the limiting sleeve 12 and cooperate with the spring 15 to keep the film on the limiting roller 17 in a taut state. The limiting roller 17 can rotate along the connecting shaft 16, which facilitates the forward conveying of the film for curing.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The height adjustment mechanism 6 includes a first limiting sleeve 8, a first telescopic rod 9, a connecting frame 10, and a driving cylinder 11. Multiple sets of first limiting sleeves 8 are fixedly installed at the bottom of the fixed frame 5. The first telescopic rod 9 is slidably connected inside the first limiting sleeve 8. The connecting frame 10 is fixedly connected to the bottom of the first telescopic rod 9. The driving cylinder 11 is fixedly installed at the bottom of the connecting frame 10. The output end of the driving cylinder 11 is fixedly connected to the fixed frame 5.

[0023] When it is necessary to adjust the top height of the limiting roller 17, the operation of the drive cylinder 11 can drive the connecting frame 10 to move up and down. At this time, the first telescopic rod 9 can be driven to move up and down along the inside of the first limiting sleeve 8, so that the thicker film can be brought close to the UV lamp 4 for curing.

[0024] Please see Figures 1-4The top fixing mechanism 3 includes a top fixing frame 18, a plug-in seat 19, a first connecting seat 20, and a second connecting seat 21. The bottom of the top fixing frame 18 is fixedly connected to the plug-in seat 19, which is inserted into the fixing frame 1. The sides of the fixing frame 1 and the top fixing frame 18 are fixedly connected to the second connecting seat 21 and the first connecting seat 20. The top fixing mechanism 3 also includes a hinge seat 23, a threaded rod 24, a threaded sleeve 25, a knob 26, and a second washer 27. The first connecting seat 20 has an installation groove 22. The second connecting seat 21 is hinged to the hinge seat 23. The top of the hinge seat 23 is fixedly installed with the threaded rod 24. The threaded rod 24 is threadedly connected to the outside of the threaded sleeve 25. The top of the threaded sleeve 25 is fixedly installed with the knob 26. The outside of the threaded sleeve 25 is fixedly connected with the second washer 27, which fits against the top of the first connecting seat 20.

[0025] During the installation of the top fixed frame 18, the plug-in seat 19 is inserted into the inside of the fixed frame 1, and then the hinge seat 23 is rotated along the second connecting seat 21. At this time, the threaded sleeve 25 can be inserted into the inside of the mounting groove 22. Then, the knob 26 is used to drive the threaded sleeve 25 to rotate, so that the second gasket 27 and the first connecting seat 20 are always in contact, thereby completing the fixed installation of the top fixed frame 18.

[0026] Please see Figure 4 The top of the fixed frame 1 and the four corners of the corresponding plug-in 19 are provided with clearance grooves 28. The clearance grooves 28 on the fixed frame 1 facilitate the insertion of the plug-in 19 into the interior of the fixed frame 1.

[0027] In use, the UV lamp 4 is first fixedly installed inside the top fixing mechanism 3, which can be detached from the fixing frame 1. This facilitates replacement and maintenance of the UV lamp 4 after it ages. The auxiliary support mechanism 7 ensures the film remains taut during curing, preventing wrinkles. The height adjustment mechanism 6 adjusts the height of the auxiliary support mechanism 7, allowing thicker adhesives to approach the UV lamp 4 for more complete curing. The film to be cured passes through the top of the limiting roller 17, where a spring 15 provides pressure, causing the first telescopic rod 9 to move upwards along the inside of the limiting sleeve 12. This, in conjunction with the spring 15, ensures the film on the limiting roller 17 remains taut. The positioning roller 17 can rotate along the connecting shaft 16, which facilitates the forward conveying and curing of the film. When the top height of the positioning roller 17 needs to be adjusted, the drive cylinder 11 can drive the connecting frame 10 to move up and down. At this time, the first telescopic rod 9 can be driven to move up and down along the inside of the first limiting sleeve 8, so that the thicker film can be brought closer to the UV lamp 4 for curing. When the top fixing frame 18 is installed, the plug-in seat 19 is inserted into the inside of the fixing frame 1, and then the hinge seat 23 is rotated along the second connecting seat 21. At this time, the threaded sleeve 25 can be inserted into the inside of the mounting groove 22. Then, the knob 26 is used to drive the threaded sleeve 25 to rotate, so that the second gasket 27 and the first connecting seat 20 are always in contact, thus completing the fixed installation of the top fixing frame 18.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
