Description

Technical Field

[0001] This utility model relates to the field of self-adhesive labels, and more specifically, to a device for uniformly coating a substrate with silicone for self-adhesive labels. Background Technology

[0002] Self-adhesive labels, also known as self-adhesive labels, instant labels, etc., are different from traditional labels. They do not require glue, paste, or water, are virtually pollution-free, save labeling time, and are convenient and quick to use in various occasions.

[0003] In the production process of self-adhesive labels, the uniformity of silicone oil coating on the substrate directly affects the peel performance and printability of the label. Currently, the industry generally uses silicone coating equipment to coat the substrate with silicone oil.

[0004] For example, patent (CN208894506U) discloses a silicone oil coating device for label paper. The device uses a roller to immerse itself in silicone oil and applies the silicone oil carried out by the roller surface to the label paper, reducing the use of silicone oil. At the same time, the silicone oil recycling structure on the second roller recycles the silicone oil into the silicone oil tank for reuse. Therefore, it has the technical advantage of less coating and recyclability compared to the prior art.

[0005] When using the above technology, the following technical problems were found in the existing technology: it cannot adapt to substrates of different thicknesses and materials, resulting in uneven silicone oil coating, which affects the subsequent use performance of the label, easily causes silicone oil accumulation, and affects the appearance quality of the product and subsequent processing. To address this, we designed a device for uniformly coating silicone substrates for self-adhesive labels to provide another technical solution to the above technical problems. Utility Model Content

[0033] Please see Figure 1-8 A device for uniformly coating a substrate for self-adhesive labels with silicone includes a bottom support frame 1, a top support frame 2 fixed to the top of the bottom support frame 1, a spray pipe 8 fixed to one end inside the top support frame 2, and a liquid injection mechanism for supplying liquid to the spray pipe 8 at one end of the top of the top support frame 2.

[0034] A vertical scraper 13 is provided at the bottom of the top support frame 2, and an adjustment mechanism for adjusting the position of the vertical scraper 13 is provided inside the top support frame 2.

[0035] A drying mechanism is provided at the other end of the top support frame 2;

[0036] The liquid injection mechanism includes a storage tank 3, which is fixed to the top of the top support frame 2. A first drive motor 4 is bolted to one end of the storage tank 3. A longitudinal rotating rod 9 is fixed to the output end of the first drive motor 4. A material pump 5 is bolted to the outside of the storage tank 3. The input end of the material pump 5 is connected to the storage tank 3. The output end of the material pump 5 is connected to the spray pipe 8. The spray pipe 8 is located inside the top support frame 2 and is fixedly connected to the top support frame 2.

[0037] Here, the operation of the first drive motor 4 allows the silicone oil inside the storage tank 3 to be stirred, preventing the silicone oil from settling, improving the quality of silicone oil spraying, and also reducing air bubbles inside the silicone oil.

[0038] The adjustment mechanism includes a second drive motor 6, which is bolted to the top of the top support frame 2. A vertical threaded rod 10 is fixed to the output end of the second drive motor 6. An L-shaped lifting plate 12 is threadedly connected to the outer side of the vertical threaded rod 10. Both ends of the L-shaped lifting plate 12 are slidably connected to vertical smooth rods 11. Through the operation of the second drive motor 6, the vertical threaded rod 10 can rotate, thereby allowing the L-shaped lifting plate 12 to slide vertically on the outer side of the vertical smooth rods 11.

[0039] The adjustment mechanism also includes a U-shaped mounting bracket 19. A third drive motor 20 is bolted to one end of the U-shaped mounting bracket 19. A first longitudinal threaded rod 21 is fixed to the output end of the third drive motor 20. A second longitudinal threaded rod 22 is fixed to the end of the first longitudinal threaded rod 21 away from the third drive motor 20. The threads of the first longitudinal threaded rod 21 and the second longitudinal threaded rod 22 have opposite directions. A longitudinal slider 23 is threadedly connected to the outer sides of both the first longitudinal threaded rod 21 and the second longitudinal threaded rod 22. The bottom of the longitudinal slider 23 is rotatably connected to... An inclined rotating column 24 is rotatably connected to a rectangular connecting block 18 via a pin at its bottom. A longitudinal connecting column 17 is rotatably connected to the inside of the rectangular connecting block 18 via a bearing. An L-shaped mounting plate 14 is fixed to both ends of the longitudinal connecting column 17. A vertical scraper 13 is fixed inside the L-shaped mounting plate 14. A longitudinal rotating column 16 is also fixed inside the L-shaped mounting plate 14. An arc-shaped fixing block 15 is rotatably connected to both ends of the longitudinal rotating column 16 via a bearing. The top of the arc-shaped fixing block 15 is fixedly connected to the L-shaped lifting plate 12.

[0040] The top of the longitudinal slider 23 is provided with a dovetail groove, and the bottom of the U-shaped mounting bracket 19 is fixed with a dovetail slider. The longitudinal slider 23 and the U-shaped mounting bracket 19 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. The setting of the dovetail slider and the dovetail groove allows the longitudinal slider 23 to slide at the bottom of the U-shaped mounting bracket 19. The movement of the longitudinal slider 23 allows the rectangular connecting block 18 to move through the oblique rotating column 24.

[0041] The U-shaped mounting bracket 19 is internally connected to a longitudinal support column 25 via a bearing. The outer side of the longitudinal support column 25 is fixedly connected to the L-shaped lifting plate 12, thereby enabling the U-shaped mounting bracket 19 to rotate on the outer side of the longitudinal support column 25.

[0042] Here, the operation of the second drive motor 6 enables the vertical threaded rod 10 to rotate. The rotation of the vertical threaded rod 10 enables the L-shaped lifting plate 12 to slide vertically on the outside of the vertical light rod 11, thereby allowing the position and height of the vertical scraper 13 to be adjusted so as to adjust the coating thickness of the silicone oil.

[0043] The operation of the third drive motor 20 enables the first longitudinal threaded rod 21 and the second longitudinal threaded rod 22 to rotate. The rotation of the first longitudinal threaded rod 21 and the second longitudinal threaded rod 22 enables the longitudinal slider 23 to move inside the U-shaped mounting bracket 19, thereby causing the two longitudinal sliders 23 to move in opposite directions. The movement of the two longitudinal sliders 23 causes the rectangular connecting block 18 to move through the oblique rotating column 24. The movement of the rectangular connecting block 18 causes the L-shaped mounting plate 14 to rotate around the longitudinal rotating column 16 through the longitudinal connecting column 17. The rotation of the L-shaped mounting plate 14 causes the vertical scraper 13 to rotate, thereby allowing the vertical scraper 13 to rotate around the longitudinal rotating column 16, thus adjusting the scraping angle of the vertical scraper 13.

[0044] The drying mechanism includes a drying chamber 7. Multiple circular fans 26 are evenly distributed and fixed at the top of the drying chamber 7. Heating tubes 27 are fixed inside the drying chamber 7. Ventilation holes are provided at the bottom of the drying chamber 7. Air can enter the drying chamber 7 through the operation of the circular fans 26. The operation of the heating tubes 27 can increase the heat of the air inside the drying chamber 7. The ventilation holes allow air to be sprayed onto the surface of the label, thereby drying the silicone-coated label.

[0045] By adjusting the mechanism, the position and height of the vertical scraper 13 can be adjusted to precisely adapt to substrates of different thicknesses and materials, ensuring a consistent silicone oil layer thickness and improving the uniformity of label peeling. The angle of the vertical scraper 13 is adjustable, allowing for quick adjustment of the optimal scraping angle for silicone oils of different viscosities, adapting to different ambient temperatures and process requirements.

[0046] During use: The operation of the first drive motor 4 allows the silicone oil inside the storage tank 3 to be stirred, preventing the silicone oil from settling, improving the quality of silicone oil spraying, and also reducing air bubbles inside the silicone oil.

[0047] The operation of the second drive motor 6 enables the vertical threaded rod 10 to rotate. The rotation of the vertical threaded rod 10 enables the L-shaped lifting plate 12 to slide vertically on the outside of the vertical light rod 11, thereby allowing the position and height of the vertical scraper 13 to be adjusted so as to adjust the coating thickness of the silicone oil.

[0048] The operation of the third drive motor 20 enables the first longitudinal threaded rod 21 and the second longitudinal threaded rod 22 to rotate. The rotation of the first longitudinal threaded rod 21 and the second longitudinal threaded rod 22 enables the longitudinal slider 23 to move inside the U-shaped mounting bracket 19, thereby causing the two longitudinal sliders 23 to move in opposite directions. The movement of the two longitudinal sliders 23 causes the rectangular connecting block 18 to move through the oblique rotating column 24. The movement of the rectangular connecting block 18 causes the L-shaped mounting plate 14 to rotate around the longitudinal rotating column 16 through the longitudinal connecting column 17. The rotation of the L-shaped mounting plate 14 causes the vertical scraper 13 to rotate, thereby allowing the vertical scraper 13 to rotate around the longitudinal rotating column 16, thus adjusting the scraping angle of the vertical scraper 13.

[0049] The operation of heating tube 27 increases the heat of the air inside drying chamber 7. The ventilation holes allow air to be sprayed onto the surface of the label, thereby drying the silicone-coated label.

[0050] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
