Description

Technical Field

[0001] This utility model relates to the field of UV curing coating machine technology, specifically a UV curing coating machine for light-curing release film. Background Technology

[0002] In a UV curing coating machine, UV stands for ultraviolet light. The principle of UV curing is that ultraviolet light irradiates a special adhesive, causing the adhesive to undergo a polymerization reaction and thus cure it. Under the action of ultraviolet light irradiation, the light triggers the formation of free radicals in the special adhesive.

[0003] Most existing UV curing coating machines for release films cannot adaptively adjust the position of the extrusion rollers according to the thickness of the release film. This results in the release film not being able to adhere tightly to the coating rollers, affecting the coating effect and making it inconvenient for operators to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a UV curing coating machine for photocurable release films, which solves the problem mentioned in the background art that most existing UV curing coating machines for photocurable release films cannot adaptively adjust the position of the extrusion roller according to the thickness of the photocurable release film, resulting in the photocurable release film not being able to adhere tightly to the coating roller, affecting the coating effect and making it inconvenient for operators to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a UV-curing coating machine for photocurable release film, comprising a base, a support leg fixedly connected to the bottom of the base, a mounting seat one fixedly connected to the top left end of the base, a conveying roller rotatably connected to the inner side of the mounting seat one, a mounting seat two fixedly connected to the top right end of the base, a take-up roller rotatably connected to the inner side of the mounting seat two, a servo motor fixedly connected to the front side of the mounting seat two, a limit spring fixedly connected to the top left side of the base, and a connecting seat fixedly connected to the top of the limit spring. Limiting blocks are fixedly connected to both ends of the connector. An extrusion roller is rotatably connected to the top of the connector. A second fixing seat is fixedly connected to the top right of the base. A UV curing lamp is fixedly connected to the top inner side of the second fixing seat. A first fixing seat is fixedly connected to the top left of the base. Limiting grooves are opened on both sides of the bottom of the first fixing seat. A coating roller is rotatably connected to the middle inner side of the first fixing seat. A storage tank is fixedly connected to the top of the fixing seat. A liquid suction pump is installed at the bottom of the storage tank. A discharge pipe is fixedly connected to the bottom of the liquid suction pump. A discharge hole is opened at the bottom of the discharge pipe.

[0006] Preferably, the position of the extrusion roller corresponds to the position of the coating roller, and the extrusion roller is located directly below the coating roller.

[0007] Preferably, the position of the limiting groove corresponds to the position of the limiting block, the width of the limiting groove is the same as the width of the limiting block, and the limiting block is in close contact with the inner wall of the limiting groove.

[0008] By adopting the above technical solution, and by setting up limiting grooves and limiting blocks in combination, the connecting seat can be prevented from shifting left and right by sliding the limiting blocks in the limiting grooves, so that it can only move up and down, thereby driving the extrusion roller and the coating roller to align, which facilitates the subsequent coating work and makes it convenient for workers to use.

[0009] Preferably, there are two limiting springs, which are symmetrically distributed on the front and rear sides of the base, and the tops of the two limiting springs are fixedly connected to the bottom of the connecting seat.

[0010] By adopting the above technical solution, a limiting spring and a connecting seat are set up in conjunction with the extrusion roller. When the limiting spring is extruded, it will generate a reaction force, which will act on the connecting seat, thereby pushing the connecting seat to move upward. The upward movement of the connecting seat will drive the extrusion roller to move upward, thereby automatically driving the photocurable release film to fit tightly against the lower side of the coating roller, thus improving the coating effect and making it easier for workers to use.

[0011] Preferably, there are several discharge holes, which are arranged in a linear array at the bottom of the discharge pipe, and the spacing between the discharge holes is the same.

[0012] Preferably, the output end of the servo motor passes through the front wall of the second mounting base and is fixedly connected to the front side of the take-up roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This UV curing coating machine for light-curing release film uses a limit spring, a connecting seat, and other components in conjunction with an extrusion roller. When the limit spring is compressed, it pushes the connecting seat upward through a reaction force. The upward movement of the connecting seat drives the extrusion roller upward, thereby automatically causing the light-curing release film to fit tightly against the lower side of the coating roller. This achieves self-adaptive adjustment, thereby improving the coating effect and making it easier for operators to use.

[0015] 2. This UV-curing release film coating machine, through the use of limiting grooves and limiting blocks, prevents the connecting seat from shifting left or right by sliding the limiting blocks within the limiting grooves. This ensures that the connecting seat can only move up and down, thereby aligning the extrusion roller and coating roller, facilitating subsequent coating operations and making it convenient for operators.

[0022] 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.

[0023] Example 1:

[0024] Referring to Figures 1-4, a UV-curing coating machine for photocurable release film includes a base 1. Support legs 2 are fixedly connected to the bottom of the base 1. Mounting seat 3 is fixedly connected to the top left end of the base 1. A conveying roller 4 is rotatably connected to the inner side of mounting seat 3. Mounting seat 2 5 is fixedly connected to the top right end of the base 1. A winding roller 6 is rotatably connected to the inner side of mounting seat 2 5. A servo motor 7 is fixedly connected to the front side of mounting seat 2 5. Limiting springs 8 are fixedly connected to the top left side of the base 1. A connecting seat 9 is fixedly connected to the top of each limiting spring 8. There are two limiting springs 8, symmetrically distributed on the front and rear sides of the base 1. The tops of both limiting springs 8 are fixedly connected to the bottom of the connecting seat 9. Limiting blocks 11 are fixedly connected to both ends of the connecting seat 9. An extrusion roller 10 is rotatably connected to the top of the connecting seat 9. A second fixing seat 18 is fixedly connected to the top right of the base 1. A UV curing lamp 19 is fixedly connected to the top inner side of the second fixing seat 18. A first fixing seat 12 is fixedly connected to the top left of the base 1. Limiting grooves 13 are opened on both sides of the bottom of the first fixing seat 12. A coating roller 14 is rotatably connected to the middle inner side of the first fixing seat 12. The position of the extrusion roller 10 corresponds to the position of the coating roller 14, and the extrusion roller 10 is located directly below the coating roller 14. A storage tank 15 is fixedly connected to the top of the fixing seat. A liquid suction pump 16 is provided at the bottom of the storage tank 15. A discharge pipe 17 is fixedly connected to the bottom of the liquid suction pump 16. A discharge hole 20 is opened at the bottom of the discharge pipe 17. There are several discharge holes 20, which are distributed in a linear array at the bottom of the discharge pipe 17, and the spacing between the several discharge holes 20 is the same.

[0025] Working principle: In use, the operator first passes the UV-cured release film over the upper surface of the conveyor roller 4. Then, the operator installs the limiting block 11, causing the connecting seat 9 to move downwards and compress the limiting spring 8, creating a gap between the extrusion roller 10 and the coating roller 14 for the UV-cured release film to pass through. The operator then passes the UV-cured release film between the extrusion roller 10 and the coating roller 14, passing under the UV curing lamp 19 until it extends into the take-up roller 6. When the operator releases the limiting block 11, the limiting spring 8... When squeezed, a reaction force is generated, which acts on the connecting seat 9, thereby pushing the connecting seat 9 to move upward. The upward movement of the connecting seat 9 will drive the extrusion roller 10 to move upward, thereby automatically driving the photocurable release film to fit tightly against the lower side of the coating roller 14. At this time, the operator starts the liquid suction pump 16, which draws the coating material from the storage tank 15 and coats it onto the photocurable release film through the coating roller 14. The coated photocurable release film is cured under the irradiation of the UV curing lamp 19 and is finally wound up by the winding roller 6.

[0026] Compared with related technologies, the UV curing coating machine for photocurable release film provided by this utility model has the following beneficial effects: by setting a limiting spring 8, a connecting seat 9, etc., in conjunction with the extrusion roller 10, the limiting spring 8 will push the connecting seat 9 upward through the reaction force when it is squeezed. The upward movement of the connecting seat 9 will drive the extrusion roller 10 upward, thereby automatically driving the photocurable release film to fit tightly against the lower side of the coating roller 14, realizing adaptive adjustment, thereby improving the coating effect and making it easier for workers to use.

[0027] Example 2:

[0028] Please refer to Figures 1-5. A limiting spring 8 is fixedly connected to the top left side of the base 1. A connecting seat 9 is fixedly connected to the top of the limiting spring 8. Limiting blocks 11 are fixedly connected to both ends of the connecting seat 9. An extrusion roller 10 is rotatably connected to the top of the connecting seat 9. A fixing seat 12 is fixedly connected to the top left side of the base 1. Limiting grooves 13 are opened on both sides of the bottom of the fixing seat 12. The position of the limiting groove 13 corresponds to the position of the limiting block 11. The width of the limiting groove 13 is the same as the width of the limiting block 11. The limiting block 11 is tightly fitted to the inner wall of the limiting groove 13. A coating roller 14 is rotatably connected to the middle of the inner side of the fixing seat 12.

[0029] Working principle: When the limiting spring 8 pushes the extrusion roller 10 upward through the connecting seat 9, the limiting blocks 11 located on both sides of the connecting seat 9 will also move in the limiting groove 13. Since the width of the limiting groove 13 is the same as the width of the limiting block 11, the limiting block 11 can only move up and down under the restriction of the limiting groove 13, avoiding the connecting seat 9 from shifting left and right, so that the extrusion roller 10 is always aligned with the coating roller 14, which facilitates the subsequent coating work and makes it convenient for the staff to use.

[0030] Compared with related technologies, the UV curing coating machine for photocurable release film provided by this utility model has the following beneficial effects: by setting a limiting groove 13 and a limiting block 11 for use, the limiting block 11 slides in the limiting groove 13, which can prevent the connecting seat 9 from shifting left and right, so that it can only move up and down, thereby driving the extrusion roller 10 to align with the coating roller 14, which facilitates the subsequent coating work and makes it convenient for workers to use.

[0031] 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.
