Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically a heating device for precise temperature control in the coating process. Background Technology

[0002] Lamination is a process of covering the surface of other materials with a thin film material. It is widely used in industries such as packaging, printing, and construction to improve the durability and visual appeal of products. Depending on the characteristics of the material, lamination can be divided into hot lamination and cold lamination. Hot lamination uses heat to bond the film to the object being covered, while cold lamination uses an adhesive that does not require heating. This process not only enhances protective properties such as waterproofing, scratch resistance, and UV protection, but also improves the appearance, meeting the market's demand for both functionality and aesthetics.

[0003] In the existing coating heating process, due to the time delay of the temperature control system, the temperature in some areas may be too low or too high. Too low a temperature may cause the film material to not adhere firmly, which in turn affects the adhesion between the film and the substrate, leading to problems such as wrinkling and peeling. On the other hand, too high a temperature may cause the film material to deform or burn, affecting the appearance and performance of the finished product, thus directly affecting the overall coating effect.

[0004] Therefore, this utility model provides a heating device for precise temperature control in the coating process to solve the above problems. Utility Model Content

[0015] The beneficial effects of this utility model are as follows:

[0016] By incorporating adjustment components, a misalignment plate, a second insulation layer, and a condenser tube, the heat generated by the heating element is first isolated within its internal space to ensure a continuous and stable heat supply. Then, the channels created by the misalignment of the misalignment plate and the rotating drum control the heat reaching the outer wall of the upper roller, preventing direct heat transfer to the upper roller surface.

Furthermore, the condenser tube accelerates temperature reduction, enhancing temperature control efficiency. Simultaneously, the heat is evenly distributed from the center outwards, resulting in a more uniform temperature during the lamination process, preventing localized overheating or undercooling, ensuring good adhesion between the film and the substrate, improving bonding quality, and ultimately guaranteeing the overall lamination effect.

[0024] 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.

[0025] This utility model provides a heating device for precise temperature control in the coating process, such as... Figures 1-5 As shown, the temperature-controlled heating device in the coating process includes an upper roller 1. A through groove is provided at the edge of the inner wall of the upper roller 1. A condenser 2 is fixedly connected inside the through groove. An adjustment component is rotatably connected to the middle of the inner wall of the upper roller 1.

[0026] The adjustment assembly includes a rotating drum 3, both ends of the outer surface of the rotating drum 3 are rotatably connected to the middle of the inner wall of the upper roller 1, one end of the rotating drum 3 is fixedly connected to a turntable 4, and the inner wall of the rotating drum 3 is fixedly connected to a first heat insulation layer 5.

[0027] A misalignment plate 6 is fixedly connected to the inner wall of the upper roller 1 on the outer periphery of the rotating drum 3. A second heat insulation layer 7 is fixedly connected to the outer surface of the misalignment plate 6. The misalignment plate 6, together with the rotating drum 3, first isolates the heat generated by the heating element 8 within its internal space to ensure a continuous and stable supply of heat. The first heat insulation layer 5 and the second heat insulation layer 7 ensure the effect of temperature isolation. Then, the rotating drum 3 is driven to rotate by the turntable 4, and the channel created by the misalignment of the misalignment plate 6 and the rotating drum 3 controls the heat reaching the outer wall of the upper roller 1, preventing the heat from being directly transferred to the surface of the upper roller 1. This reduces the risk of film material deformation or damage due to overheating, reduces energy waste, and improves heating efficiency. The condenser tube 2 can accelerate the temperature reduction rate and improve the temperature control efficiency to achieve high-efficiency temperature control. At the same time, the heat is evenly distributed from the center to the surrounding area, which can make the temperature more uniform during the lamination process, avoid local overheating or overcooling, ensure good adhesion between the film and the substrate, improve the bonding quality, and thus ensure the overall lamination effect.

[0028] The number of misaligned plates 6 is several, arranged in an intermittent ring. The outer surface of the rotating drum 3 is provided with square grooves corresponding to the misaligned plates 6, arranged in an intermittent ring, which facilitates the reservation of heat transfer channels in all directions inside the upper roller 1, ensuring the uniformity of heat dissipation.

[0029] A heating element 8 is fixedly installed on the inner wall of the rotating drum 3. A first temperature-conducting layer 9 is fixedly connected to the outer surface of the heating element 8. When the heating element 8 is started by an external power source, it can heat the air in the first temperature-conducting layer 9, and then the heat is transferred out through the first temperature-conducting layer 9.

[0030] A second heat-conducting layer 10 is rotatably connected to the middle of the outer surface of the upper roller 1. A rubber layer 11 is fixedly connected to the outer surface of the second heat-conducting layer 10. After heat enters the outer wall of the upper roller 1, it is transferred to the workpiece to be coated by the second heat-conducting layer 10 to achieve coating. The elasticity of the rubber layer 11 enables the upper roller 1 to better adapt to substrates of various thicknesses and hardnesses, ensuring good contact and pressure distribution during the coating process, and ensuring that a suitable temperature is maintained during the coating process, thereby improving the adhesion quality of the film.

[0031] Sliding blocks 12 are fixedly connected to both ends of the outer surface of the upper roller 1. A cylinder 13 is fixedly connected to the upper surface of the sliding block 12. When the cylinder 13 is activated, the sliding block 12 moves up and down, thereby adjusting the distance between the upper roller 1 and the lower roller 18 to accommodate substrates of different thicknesses and to adjust the pressure on the substrate.

[0032] A vertical plate 14 is fixedly connected to the lower surface of the cylinder 13, and a base plate 15 is fixedly connected to the lower surface of the vertical plate 14. Extension plates 16 are fixedly connected to both sides of the base plate 15. A fixing groove is provided on one side of the upper surface of the extension plate 16, and a sliding groove adapted to the sliding block 12 is provided on one side of the vertical plate 14 to limit the sliding block 12 and ensure its smooth movement. The extension plate 16 increases the contact area with the bottom when the device is placed, thereby increasing the stability when placed. Bolts are also provided to pass through the fixing groove to fix the device in the required position, thereby further improving the stability of the device when placed.

[0033] A first motor 17 is fixedly installed on one side of the upright plate 14. The output end of the first motor 17 is fixedly connected to the lower roller 18. When the external power supply starts the first motor 17, it drives the lower roller 18 to rotate, so as to realize the conveying of the substrate. It can also drive the second heat-conducting layer 10 to rotate, so as to achieve temperature uniformity, avoid local overheating or overcooling, and facilitate the quality and stability of the product.

[0034] Working steps: First, use bolts to pass through the fixing groove to fix the device in the required position. Then, start the cylinder 13 to drive the sliding block 12 to move up and down, thereby adjusting the distance between the upper roller 1 and the lower roller 18. Next, start the heating element 8 with an external power supply to heat the air in the first temperature-conducting layer 9, and then transfer it out through the first temperature-conducting layer 9. Next, the heat generated by the heating element 8 is first isolated in the space inside by the misalignment plate 6 combined with the rotating drum 3. The first temperature insulation layer 5 and the second temperature insulation layer 7 ensure the temperature isolation effect. The rotating drum 3 is driven to rotate by the turntable 4, and the channel created by the misalignment of the misalignment plate 6 and the rotating drum 3 controls the heat reaching the outer wall of the upper roller 1. Finally, start the first motor 17 with an external power supply to drive the lower roller 18 to rotate, so as to realize the transport of the substrate and drive the second temperature-conducting layer 10 to rotate, so as to achieve temperature uniformity.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
