Description

Technical Field

[0001] This utility model belongs to the technical field of glassine paper production process, specifically relating to a silicon-on-glassine device for glassine paper. Background Technology

[0002] Glassine paper, as a high-smoothness, high-density release paper substrate, relies on the core production process of uniformly and stably coating silicone oil onto the surface of the base paper and curing it to form a release layer. Traditional silicone oil coating equipment typically includes basic units such as coating rollers, silicone oil supply, and drying. However, in actual production, it has been found that if the temperature of the base paper is low before coating, the viscosity of the silicone oil will increase sharply upon contact with the paper, making it difficult to spread and penetrate evenly, easily resulting in defects such as uneven coating and fisheyes, affecting the release effect. In addition, if the heat supply is uneven or inefficient in the drying process after coating, it may cause incomplete curing or excessive cross-linking of the silicone oil, also affecting product quality. Although existing equipment has preheating or drying functions, the preheating effect is often limited, the preheating range is short, and the humid and hot exhaust gas generated during the drying process is difficult to remove in a timely manner, restricting the improvement of production efficiency and product consistency.

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a glassine paper silicone device, including a box, a coating roller, and a silicone oil tank. One end of the box has a paper inlet communicating with the inside of the box, and the other end has a paper outlet communicating with the inside of the box.

[0013] like Figure 1-2 As shown, the glassine paper silicone device includes a housing 1, a coating roller 2, and a silicone oil tank 3. One end of the housing 1 has a paper inlet 4 connecting to the interior of the housing 1, and the other end has a paper outlet 5 connecting to the interior of the housing 1. Guide rollers 6 are respectively installed at the paper inlet 4 and the paper outlet 5. The coating roller 2 is located inside the housing 1 and is driven up and down by a lifting drive mechanism. Support rollers 7 are respectively installed on both sides below the coating roller 2. The silicone oil tank 3 is located outside the housing 1, contains silicone oil, and supplies silicone oil to the coating roller 2. A heating device for heating and maintaining the temperature of the silicone oil is installed on the silicone oil tank 3. The housing 1 is equipped with a preheating mechanism and a drying mechanism. The preheating mechanism is located between the paper inlet 4 and the coating roller 2, and includes an upper preheating plate 8 and a lower preheating plate 9. A front channel 10 for glassine paper to pass through is formed between the upper preheating plate 8 and the lower preheating plate 9. The drying mechanism is located between the paper outlet 5 and the coating roller 2, and includes an upper drying plate 11 and a lower drying plate 12. A rear channel 13 for glassine paper to pass through is formed between the upper drying plate 11 and the lower drying plate 12. The upper preheating plate 8, the lower preheating plate 9, the upper drying plate 11, and the lower drying plate 12 are heated by heating mechanisms. The base paper for producing glassine paper enters the housing 1 through the paper inlet 4, passes through the front channel 10, below the coating roller 2, and the rear channel 13 in sequence, and then leaves the housing 1 through the paper outlet 5. The coating roller 2 descends and contacts the paper, transferring the silicone oil provided in the silicone oil tank 3 to the surface of the paper. The preheating unit preheats the paper, allowing the silicone oil to quickly and evenly diffuse and penetrate the paper surface. The drying unit then rapidly dries the silicone oil.

[0014] Furthermore, a front air blower mechanism is installed at the paper inlet 4, and a rear air blower mechanism is installed at the paper outlet 5. The front and rear air blower mechanisms have the same structure. The front air blower mechanism includes an air duct 14, which is located above the glassine paper. An air distribution plate 15 is fixedly connected to the air duct 14. One side of the air distribution plate 15 has an elongated air hole 16 that connects to the front air duct 14. The front air duct 14 is rotatably connected to the housing 1 and is connected to the hot air system. The angle of the elongated air hole 16 is adjustable after the air duct 14 is rotated. The hot air system includes a fan, a heater, etc., to provide clean hot air.

[0015] Furthermore, the front blower mechanism is located inside the housing 1, with the elongated air holes 16 in the front blower mechanism angled downwards towards the paper inlet 4. The rear blower mechanism is located outside the housing 1. The front blower mechanism blows away dust from the paper surface, preventing dust from affecting the silicone coating effect. Simultaneously, the front blower mechanism can carry away a certain amount of heat from the front channel 10 and apply it to the paper surface, extending the preheating length and creating a preheating process with gradually increasing temperature. The elongated air holes 16 of the rear blower mechanism are angled outwards, creating a certain negative pressure in the rear channel 13 near the paper outlet 5, carrying away the hot and humid air generated during the drying process and accelerating the curing of the silicone oil on the paper surface.

[0016] Furthermore, the lifting drive mechanism is an electric push rod 17. Slider 18s are rotatably connected to both ends of the coating roller 2, and the sliders 18 are respectively mounted on vertical slide rails 19. The sliders 18 are fixedly connected to each other by a fixing plate 20. The output shaft of the electric push rod 17 is connected to the fixing plate 20. The coating roller 2 can be raised and lowered to apply pressure to the paper, thereby uniformly transferring silicone oil to the paper surface. The coating roller 2 is driven to rotate by its own rotation drive mechanism. The coating roller 2 is existing technology; any coating roller 2 commonly used in glassine paper production processes can be selected, such as a gravure roller, a micro-engraving roller, or a multi-roller combination coating.

[0017] Furthermore, the heating device and heating mechanism are resistance wire heaters, and the upper preheating plate 8, lower preheating plate 9, upper drying plate 11, and lower drying plate 12 are all aluminum plates. Temperature sensors are installed in the silicone oil tank 3, the front channel 10, and the rear channel 13. Utilizing the good thermal conductivity of aluminum plates, heat radiation is generated on the glassine paper passing through the front channel 10 and the rear channel 13. The temperature in the front channel 10 differs from that in the rear channel 13. The temperature in the front channel 10 is controlled between 80-120℃, preheating the paper. The temperature in the rear channel 13 is controlled between 150-180℃, homogenizing and drying the silicone oil. The silicone oil in the silicone oil tank 3 is maintained at a temperature between 120-180℃ to ensure good flow.

[0018] It is worth mentioning that the technical features of the resistance wire heater, cylinder, electric push rod, coating roller and other technologies involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0019] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
