Technical Field

[0001] The present invention relates to the technical field of thin film coating, in particular to a coating device for thin film production. Background Art

[0002] As a high-performance material, film is widely used in packaging, electronics, medical and other fields. Its performance depends to a large extent on the quality of the coating process. UV light-curing film, as a type of film, generally includes a base film and a UV adhesive layer. The base film is commonly PET film, and the UV adhesive layer is a light-curing layer. During the coating process, the UV glue is placed in the glue tank, and the glue roller is dipped into the glue tank to dye the glue and apply the UV glue on the base film. The UV glue is then treated with a photosensitive device to solidify it to form a UV adhesive layer and finally form a UV light-curing film.

[0003] In the prior art, when a coating roller is used to roll-coat the base film, the thickness of the UV glue dipped on the coating roller is uneven, and the UV glue coated on the base film after coating is unevenly distributed, affecting the coating quality of the base film, and thus causing the production quality of the film to fail to achieve the expected effect. Summary of the Invention

[0007] By adopting the above technical solution, the base film on the unwinding roller is fed into the glue coating box from the feeding port, the base film bypasses multiple guide rollers and passes through the gap channel between the adjustment roller and the glue coating roller, and then the base film is fed into the ultraviolet irradiation box, and the base film is sent out from the discharging port and wound and fixed on the winding roller. When the base film is glued, the base film is transported by the cooperation of the unwinding roller and the winding roller. During the base film transportation process, the driving motor is started to drive the glue coating roller to rotate, prompting the glue coating roller to dip the UV glue in the glue tank and apply the UV glue on the base film. During the roller coating process of the glue coating roller, the scraping mechanism can scrape the glue on the glue coating roller to prompt the glue on the glue coating roller to be flat and uniform, so as to achieve uniform coating of the base film and ensure the coating quality of the UV glue.

[0028] 2. The glue coating roller drives the first rotating shaft to rotate through the first transmission assembly. When the second magnetic block rotates to approach the first magnetic block, the second magnetic block compresses the spring and causes the slide to push the impact block downward to hit the scraper. When the second magnetic block gradually moves away from the first magnetic block, the first magnetic block drives the impact block upward and reset under the action of the spring force. In this way, the impact block can reciprocate and hit the scraper during the rotation of the first rotating shaft, causing the scraper to vibrate and shake off the rubber material, thereby realizing the recovery of the rubber material.

[0029] 3. During the gluing process, the gluing roller will drive the rotating shaft to rotate through the second transmission component, causing the fan blades to rotate and blow air into the ventilation pipe. The air nozzle will then blow the gas onto the base film and the bristles to clean the gluing surface of the base film and the bristles, thereby reducing the possibility of dust and impurities adhering to the base film affecting the gluing quality and ensuring the gluing quality.

[0038] The present invention discloses a coating device for thin film production, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a base 1, a support frame 2, a glue coating box 3 and an ultraviolet irradiation box 5. The support frame 2 is installed on the top surface of the base 1. A reel 21 and a reel 22 located on the top of the reel 21 are horizontally rotatably provided on the inner wall of the support frame 2; the glue coating box 3 is fixedly connected to the top surface of the base 1 on one side of the support frame 2. The glue coating box 3 is provided with a feeding port 31 on the side wall close to the support frame 2. A glue tank 4 for containing UV glue is fixedly connected to the inner wall of the bottom end of the glue coating box 3. A driving motor 41 is horizontally installed on the outer wall of the glue coating box 3. The driving motor 4 The output end is coaxially fixedly connected to a glue roller 42 located in the glue tank 4. The glue roller 42 rotates with the inner wall of the glue tank 4. An adjustment roller 32 is rotatably connected to the inner wall of the glue box 3 and is located on the top of the glue roller 42 and is coaxial with the glue roller 42. The adjustment roller 32 cooperates with the glue roller 42 to form a gap channel for the base film to pass through. The ultraviolet irradiation box 5 is installed on the top surface of the glue box 3. The ultraviolet irradiation box 5 is connected to the glue box 3 to allow the base film to enter. The ultraviolet irradiation box 5 is provided with a discharge port 51 on the side wall near the support frame 2.

[0039] The base film on the unwinding roller 21 is fed into the glue coating box 3 from the feeding port 31, and the base film passes through the gap channel between the adjusting roller 32 and the glue coating roller 42 and enters the ultraviolet irradiation box 5, and the base film is sent out from the discharging port 51 and wound and fixed on the winding roller 22. When the base film is glued, the base film is transported by the cooperation of the unwinding roller 21 and the winding roller 22. During the base film transportation process, the driving motor 41 is started to drive the glue coating roller 42 to rotate, prompting the glue coating roller 42 to dip the UV glue in the glue tank 4 and apply the UV glue on the base film. When the glued base film enters the ultraviolet irradiation box 5, the glue on its surface will be cured, thereby completing the coating of the UV glue for winding and finishing.

[0040] like Figure 1 and Figure 2 As shown, a plurality of guide rollers 33 located on the side of the adjustment roller 32 close to the feed port 31 are horizontally rotatably connected to the inner wall of the glue coating box 3, and the plurality of guide rollers 33 are coaxial with the glue coating roller 42. A first opening is provided on the top surface of the glue coating box 3, and a second opening corresponding to the first opening is provided on the bottom wall of the ultraviolet irradiation box 5. A pair of supporting rollers 52 are horizontally rotatably connected to the inner wall of the ultraviolet irradiation box 5, and the two supporting rollers 52 are coaxial with the glue coating roller 42. The ultraviolet irradiation box 5 has ultraviolet lamp groups 53 evenly spaced on the top wall between the two supporting rollers 52.

[0041] The guide rollers 33 and support rollers 52 are arranged to guide and support the transported base film, and the ultraviolet lamp group 53 is set to irradiate the glue-coated surface of the base film to promote the curing of the UV glue and facilitate the winding and arrangement of the base film.

[0042] like Figure 2 and Figure 3 As shown, a scraping mechanism 6 is provided in the glue tank 4 and is located on one side of the glue coating roller 42. The scraping mechanism 6 includes a pair of electric push rods 61 and a scraper 62. The pair of electric push rods 61 are horizontally installed on the inner wall of the glue tank 4 on one side of the glue coating roller 42. The extension and retraction directions of the electric push rods 61 are arranged horizontally radially along the glue coating roller 42, and the scraper 62 is horizontally fixed to the output ends of the two electric push rods 61.

[0043] Start the electric push rod 61 to drive the scraper 62 to move and adjust the gap distance between the scraper 62 and the glue coating roller 42. When the glue coating roller 42 dips the glue for coating, the glue will be scraped by the scraper 62 when passing through the gap between the scraper 62 and the glue coating roller 42, removing excess glue on the glue coating roller 42 and making the glue smooth and uniform. By controlling the gap distance between the scraper 62 and the glue coating roller 42, the glue coating thickness can be controlled to ensure the coating quality.

[0044] like Figure 1 、 Figure 2 and Figure 4As shown, a support plate 34 located at the top of the scraper 62 is fixedly connected horizontally to the inner wall of the glue coating box 3. The top surface of the support plate 34 is horizontally connected to a first magnetic block 342 through two vertical springs 341. The bottom surface of the first magnetic block 342 is fixedly connected to a slide plate 343 that vertically penetrates the support plate 34. The slide plate 343 slides with the support plate 34. The bottom surface of the slide plate 343 is fixedly connected to a collision block 344 located at the top of the scraper 62. The inner wall of the glue coating box 3 is horizontally connected to the top of the first magnetic block 342. The first rotating shaft 35 is coaxial with the glue coating roller 42. The outer wall of the first rotating shaft 35 is fixedly connected to the second magnetic block 352 located on the top of the first magnetic block 342 through the connecting plate 351. The top surface of the first magnetic block 342 and the end surface of the second magnetic block 352 away from the connecting plate 351 have the same magnetic properties. The end of the glue coating roller 42 away from the driving motor 41 is provided with a first transmission assembly 43 located outside the glue coating box 3. The first transmission assembly 43 can enable the glue coating roller 42 to drive the first rotating shaft 35 to rotate.

[0045] During the gluing process, the gluing roller 42 will drive the first rotating shaft 35 to rotate through the first transmission assembly 43. When the first rotating shaft 35 drives the second magnetic block 352 to rotate close to the first magnetic block 342, the second magnetic block 352 will compress the spring 341 and cause the slide plate 343 to push the impact block 344 to move down and impact the scraper 62. When the first rotating shaft 35 drives the second magnetic block 352 to gradually move away from the first magnetic block 342, the first magnetic block 342 drives the impact block 344 to move up and reset under the elastic force of the spring 341, so that the impact block 344 can reciprocate and impact the scraper 62 during the rotation of the first rotating shaft 35, causing the scraper 62 to vibrate and shake off the rubber material, thereby realizing the recovery of the rubber material.

[0046] like Figure 1 and Figure 4 As shown, the first transmission assembly 43 includes a first pulley 431, a second pulley 432 and a first belt 433. The first pulley 431 is coaxially fixed to the outer wall of the end of the glue coating roller 42 away from the drive motor 41, and the second pulley 432 is coaxially fixed to the outer wall of the end of the first rotating shaft 35 away from the drive motor 41. The first belt 433 is tensioned and sleeved on the outside of the first pulley 431 and the second pulley 432. The first belt 433 links the first pulley 431 and the second pulley 432.

[0047] With the cooperation of the first pulley 431, the second pulley 432 and the first belt 433, the glue coating roller 42 will drive the first rotating shaft 35 to rotate during the rotation process, thereby realizing the transmission of kinetic energy during the rotation of the glue coating roller 42 and reducing the use of drive units.

[0048] like Figure 2 As shown, a pair of vibration motors 45 are installed on the outer wall of the glue tank 4.

[0049] Starting the vibration motor 45 can vibrate the UV glue in the glue tank 4, causing bubbles in the UV glue to burst, thereby reducing the impact of bubbles on coating uniformity and improving the quality of base film glue coating.

[0050] like Figure 1 and Figure 2 As shown, a pressure roller 311 and a brush roller 312 located on the top of the pressure roller 311 are horizontally connected to the inner wall of the feed port 31, and the pressure roller 311 and the brush roller 312 are both coaxial with the glue coating roller 42. Bristles are arranged on the outer peripheral surface of the brush roller 312, and the bristles can contact the base film that bypasses the bottom of the pressure roller 311.

[0051] The pressure roller 311 is used to limit and guide the base film passing through the feed port 31. During the base film transportation process, the bristles on the brush roller 312 will contact the base film to remove dust and impurities on the surface of the base film to be coated, reducing the impact of dust and impurities on the coating quality.

[0052] like Figure 1 、 Figure 2 and Figure 6 As shown, a ventilation pipe 7 coaxial with the glue roller 42 is horizontally rotatably connected on the inner wall of the glue coating box 3, and the end of the ventilation pipe 7 away from the drive motor 41 extends to the outer wall of the glue coating box 3 and is open. The ventilation pipe 7 is connected to the external environment, and a plurality of air nozzles 71 are arranged on the side wall of the ventilation pipe 7. The plurality of air nozzles 71 are evenly spaced along the axial direction of the ventilation pipe 7 and are arranged obliquely downward to point to the pressure roller 311 and the brush roller 312. The ventilation pipe 7 is coaxially rotatably connected to a rotating shaft 72 on the inner wall near the open end, and fan blades 73 are arranged on the outer wall of the rotating shaft 72. A filter screen 74 is installed on the inner wall of the open end of the ventilation pipe 7, and the end of the rotating shaft 72 passes through the filter screen 74 and extends to the outside of the ventilation pipe 7. The rotating shaft 72 rotates in coordination with the filter screen 74. A second transmission assembly 44 is provided on the outer wall of the glue coating box 3 near the open end of the ventilation pipe 7. The second transmission assembly 44 can make the glue coating roller 42 drive the rotating shaft 72 to rotate.

[0053] Under the action of the second transmission component 44, the glue coating roller 42 will drive the rotating shaft 72 to rotate during the rotation process, causing the fan blades 73 to rotate and blow air into the ventilation pipe 7. The wind blown into the ventilation pipe 7 is then ejected through the air nozzle 71 to spray the base film and bristles that bypass the pressure roller 311, thereby removing dust and impurities adhered to the glue coating surface of the base film and the bristles, and improving the cleaning effect of the glue coating surface of the base film. The filter screen 74 is set to filter and block dust and impurities to ensure the cleanliness of the air flow blown by the air nozzle 71.

[0054] like Figure 1 、 Figure 2 and Figure 6As shown, the second transmission assembly 44 includes a second rotating shaft 441, a gear box 442, a third pulley 443, a fourth pulley 444 and a second belt 445. The second rotating shaft 441 is horizontally rotatably connected to the outer wall of the glue coating box 3 on the side where the open end of the ventilation pipe 7 is located. The second rotating shaft 441 is coaxial with the glue coating roller 42. The third pulley 443 is coaxially fixed to the outer wall of the end of the glue coating roller 42. The fourth pulley 444 is coaxially fixed to the outer wall of the end of the second rotating shaft 441. The second belt 445 is tensioned on the outer walls of the third pulley 443 and the fourth pulley 444. The gear box 442 is installed on the outer wall of the glue coating box 3 on the side where the second rotating shaft 441 is located. The low-speed input end of the gear box 442 is connected to the second rotating shaft 441 through the first bevel gear set 446. The high-speed output end of the gear box 442 is connected to the rotating shaft 72 through the second bevel gear set 447.

[0055] With the cooperation of the third pulley 443, the fourth pulley 444 and the second belt 445, the glue coating roller 42 will drive the second rotating shaft 441 to rotate during the rotation process, and the second rotating shaft 441 will then drive the rotating shaft 72 to rotate through the gear box 442, thereby realizing the transmission of kinetic energy during the rotation of the glue coating roller 42, so as to prompt the fan blades 73 to rotate and blow air.

[0056] Working principle: The base film is sent into the glue coating box 3 through the pressure roller 311 and the brush roller 312. After passing through multiple guide rollers 33, the base film passes through the gap channel between the adjustment roller 32 and the glue coating roller 42, and then passes through the first and second openings to be sent into the ultraviolet irradiation box 5. After passing through the support roller 52 in the ultraviolet irradiation box 5, the base film is output from the discharge port 51 and wound and fixed on the winding roller 22. The base film can be transported by the cooperation of the unwinding roller 21 and the winding roller 22. When the transported base film is coated with glue, the drive motor 41 is started to drive The glue coating roller 42 rotates, prompting the glue coating roller 42 to dip into the UV glue in the glue tank 4 and apply the UV glue to the base film. The scraper 62 located on one side of the glue coating roller 42 can scrape the glue on the outer peripheral surface of the glue coating roller 42 during the glue coating process, remove excess glue on the glue coating roller 42, make the glue smooth, and ensure the coating quality. When the glued base film enters the ultraviolet irradiation box 5, the ultraviolet lamp group 53 can illuminate the glue-coated surface of the base film to promote the curing of the UV glue, so that the base film output from the ultraviolet irradiation box 5 can be rolled up and sorted.

[0057] During the gluing process, the gluing roller 42 drives the first rotating shaft 35 to rotate via the first transmission assembly 43. When the first rotating shaft 35 drives the second magnetic block 352 to rotate close to the first magnetic block 342, the second magnetic block 352 compresses the spring 341 and causes the slide plate 343 to push the impact block 344 downward to impact the scraper 62, causing the scraper 62 to vibrate and shake off the rubber material, thereby realizing rubber material recovery. When the first rotating shaft 35 drives the second magnetic block 352 to gradually move away from the first magnetic block 342, the first magnetic block 342 drives the impact block 344 to move upward and reset under the elastic force of the spring 341, so that the impact block 344 can reciprocate and impact the scraper 62 during the rotation of the first rotating shaft 35.

[0058] During the gluing process, the gluing roller 42 drives the rotating shaft 72 to rotate through the second transmission assembly 44, causing the fan blades 73 to rotate and blow air into the ventilation pipe 7. The air nozzle 71 then blows the gas onto the base film and the bristles, cleaning the gluing surface of the base film and the bristles, thereby reducing the possibility of dust and impurities adhering to the base film and affecting the gluing quality.

[0059] When the UV glue contained in the glue tank 4 is replaced with adhesive, the device can also be used to apply the adhesive during the production of the composite film.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
