Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0030] Referring to Figures 1-4 A paper silicon machine oven mechanism, comprising a preheating area 1, a main drying area 2 and a slow cooling area 3, the main drying area 2 is located between the preheating area 1 and the slow cooling area 3, the preheating area 1 is located at the left side of the main drying area 2, the slow cooling area 3 is located at the right side of the main drying area 2, the preheating area 1 is provided with an inlet 6, the slow cooling area 3 is provided with an outlet 7, the preheating area 1 is provided with a humidity control system 4, and the main drying area 2 is provided with an ultraviolet light curing unit 5.

[0031] Referring to Figures 2-3The preheating zone 1 is equipped with several preheating rollers 11, each with an electric heating wire 12 on its surface. The preheating rollers 11 and electric heating wires 12 on their surfaces are used to gradually increase the paper temperature and prevent sudden temperature changes from damaging the paper. The preheating rollers 11 are made of high-temperature resistant stainless steel, with a diameter of 50 mm and a length that matches the width of the paper. The electric heating wires 12 are made of nickel-chromium alloy with a moderate power density to ensure uniform heating without overheating, thereby improving the practicality of the device.

[0032] Reference Figures 1-3 The main drying zone 2 is equipped with a multi-layer hot air circulation system 21, which includes a blower 211, an exhaust fan 212, and a heater 213. The multi-layer hot air circulation system 21 in the main drying zone 2, including the top blower 211, the bottom exhaust fan 212, and the side wall heater 213, forms an upper and lower circulating airflow, ensuring that the silicone oil layer is heated evenly, thereby improving the practicality of the device.

[0033] Reference Figures 1-3 The blower 211 is located at the top of the main drying zone 2, the exhaust fan 212 is located at the bottom of the main drying zone 2, and the heater 213 is located on the side wall of the main drying zone 2. The blower 211 is a low-noise centrifugal fan with a wide flow adjustment range, which is suitable for various production environments. The heater 213 uses far-infrared heating elements with high radiation efficiency and good energy efficiency ratio, thereby improving the practicality of the device.

[0034] Reference Figure 2 , 4 The slow cooling zone 3 is equipped with a natural cooling rack 31 and a forced cooling fan 32, with the forced cooling fan 32 located above the natural cooling rack 31. The slow cooling zone 3 is equipped with a natural cooling rack 31 and a forced cooling fan 32 to steadily reduce the paper temperature and avoid deformation caused by rapid cooling, thereby improving the practicality of the device.

[0035] Reference Figures 2-4 The humidity control system 4 includes a spray head 41, which is located in the preheating zone 1 and close to the inlet 6. By adding a humidity control system 4 at the front end of the preheating zone 1, the initial humidity of the paper is pre-adjusted by spray humidification, which helps to reduce the cracking phenomenon during high-temperature drying and thus improves the practicality of the device.

By adding the ultraviolet curing unit 5 in the main drying zone 2, ultraviolet irradiation is used to promote the rapid curing of silicone oil, thereby shortening the overall drying time, improving production efficiency, and thus enhancing the practicality of the device.

[0037] Working principle: after the paper enters the preheating zone 1, the temperature is slowly raised by the preheating roller 11, so that the paper gradually adapts to the subsequent high temperature condition, then the paper enters the main drying zone 2, the top air blower 211 blows hot air to the surface of the paper, the bottom exhaust fan 212 extracts the hot and humid air, forming a continuous flow of air circulation, accelerating the evaporation process, at the same time, the side wall heater 213 continues to heat, maintaining a constant temperature field in the whole drying zone, ensuring that the silicone oil layer is uniformly heated, finally, the paper reaches the slow cooling zone 3, which is slowly cooled down through the dual action of natural cooling rack 31 and forced cooling fan 32 until it returns to room temperature.

[0038] The adhesive paper is a composite product with paper, film or special material as the surface material, glue on the back of the surface material, and silicone protective paper as the base material. In the production process of the adhesive paper in the prior art, the base paper is first coated with a layer of plastic film by a plastic coating machine, then a layer of silicone oil is compounded on the base paper by a silicone coating machine, and then dried in an oven and cooled. The silicone coating machine oven structure in the prior art directly dries the silicone oil attached to the base paper, and the paper temperature rises and falls suddenly after drying and cooling, which easily causes paper deformation, affecting drying uniformity and effect. Therefore, the present technology proposes a three-stage oven design including a preheating zone 1, a main drying zone 2 and a slow cooling zone 3, which aims to solve the paper deformation problem through the process of gradually increasing temperature, constant temperature drying and stable cooling, improve the drying quality and efficiency. Compared with the prior art, the present technology introduces the design of preheating zone 1 and slow cooling zone 3, effectively alleviates the problem of sudden temperature change of the paper during drying, significantly reduces the risk of paper deformation, improves the quality and stability of the finished product, and the main drying zone 2 adopts a multi-layer hot air circulation system 21, which not only speeds up the evaporation speed of water, but also ensures the uniform heating of the silicone oil layer, improves the drying efficiency and effect, and the overall structure is simple and reliable, easy to operate and maintain, with good applicability and promotion prospect.

[0039] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
