Description

Technical Field

[0001] This utility model relates to the field of impregnated paper technology, specifically to an impregnated paper drying device. Background Technology

[0002] Resin-impregnated paper, also known as "melamine" paper, is made by impregnating plain or printed decorative paper with amino resins (mainly melamine-formaldehyde resin and urea-formaldehyde resin), followed by drying to a specific degree, ultimately forming a resistant paper with a certain resin content and volatile matter content. This type of resistant paper can be bonded together with itself or tightly bonded to a particleboard substrate through a hot-pressing process.

[0003] In the production process of coated paper, the drying process is crucial. However, the currently widely used hot air direct blowing drying technology has significant drawbacks. This method can only achieve single-sided drying, which greatly limits production efficiency. At the same time, hot air direct blowing will cause the surface of coated paper to shake violently, resulting in wrinkles, which seriously affects product quality and is not conducive to the production of high-quality coated paper. Utility Model Content

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1-4 As shown, a paper drying device includes: a base 1, several sets of mounting plates 2 are installed on the top of the outer surface of the base 1, a controller 3 is electrically installed on one side of the outer surface of the left mounting plate 2, a first rotating roller 4 is installed on the other side of the outer surface of the left mounting plate 2, a motor 6 is fixedly installed on one side of the outer surface of the right mounting plate 2, a second rotating roller 7 is installed through the output end of the motor 6 through the outer surface of the mounting plate 2, several sets of fixing columns 5 are installed on the bottom of the outer surface of the base 1, a housing 8 is installed in the middle of the top of the outer surface of the base 1, and slots are opened on both the left and right ends of the outer surface of the housing 8. An oil storage tank 21 is installed at the rear end of the outer surface of the housing 8. Several sets of connecting blocks 23 are installed on the inner side of the oil tank 21. A heating rod 24 is installed at one end of each set of connecting blocks 23. Several sets of connecting pipes 22 are installed on the outer surface of the oil tank 21. A heating roller 18 is fixedly installed on the shaft surface of the connecting pipe 22 through the outer surface of the outer shell 8. The heating rollers 18 are arranged at different heights. A threaded coil 19 is installed inside the heating roller 18. A high thermal conductivity silicone grease 20 is installed inside the heating roller 18. An anti-stick and wear-resistant outer sleeve 17 is sleeved on the shaft surface of the heating roller 18. A liquid level sensor 25 is installed on the left side inside the oil tank 21. A temperature sensor 26 is installed at the end of the oil tank 21 opposite to the liquid level sensor 25.

[0023] With the above scheme, the base 1 serves as a basic support component, providing a stable installation platform for the entire drying device, and the fixing column 5 at the bottom of its outer surface further enhances the stability of the device. Mounting plate 2 is installed on top of base 1 to support and fix other important components. Controller 3 on the left mounting plate 2 can intelligently control the operation of the device. The first rotating roller 4 and the second rotating roller 7 driven by motor 6 on the right mounting plate 2 cooperate to achieve stable transmission of the impregnated paper. The outer shell 8 is installed at the top center of base 1. The slots on its left and right ends facilitate the entry and exit of the impregnated paper. In the oil tank 21 at the rear end, the connecting block 23 and the heating rod 24 are combined to heat the medium in the oil tank. The connecting pipe 22 connects the oil tank 21 to the heating roller 18. The threaded coil 19 and high thermal conductivity silicone grease 20 inside the heating roller 18 can efficiently conduct heat. With the anti-stick and wear-resistant outer shell 17, it can not only achieve double-sided heating and drying of the impregnated paper and improve drying efficiency, but also prevent the impregnated paper from sticking to the heating roller 18, avoid wrinkles, and ensure the quality of the impregnated paper. The liquid level sensor 25 and the temperature sensor 26 monitor the liquid level and temperature of the medium in the oil tank 21 in real time, providing data support for the stable operation of the device.

[0024] Reference Figure 2-3 As shown, further, a mounting bracket 16 is fixedly installed at one end of the shaft surface of the heating roller 18, several sets of limiting plates 15 are installed inside the outer shell 8, and the outer surface of the mounting bracket 16 is inserted into the limiting plate 15. A top cover 9 is provided at the top of the outer surface of the outer shell 8, and several sets of rotating doors 10 are provided at the middle of the bottom end of the outer surface of the top cover 9. The outer surfaces of the top cover 9 and the rotating doors 10 are installed by a rotating rod 11 passing through the outer surface. Several sets of fan boxes 12 are installed at the bottom end of the outer surface of the top cover 9 on both sides of the rotating doors 10. A fan 13 is fixedly installed inside the fan box 12, and heat dissipation holes 14 are opened between the several sets of fan boxes 12 on the outer surface of the top cover 9.

[0025] Through the above scheme, the mounting bracket 16 at one end of the surface of the heating roller 18 cooperates with the limiting plate 15 inside the outer casing 8 to fix and position the heating roller, ensuring the stability of the heating roller 18 during operation. The top cover 9 at the top of the outer casing 8 not only protects the internal components, but its rotating door 10 is also installed via a rotating rod 11, making it convenient for staff to open and inspect and maintain the internal parts of the device. The fan boxes 12 on both sides of the bottom of the top cover 9 and the internal fan 13 can accelerate airflow during the drying process, quickly transferring the heat generated by the heating roller to the impregnated paper, while simultaneously dissipating excess heat through the heat dissipation holes 14, thereby regulating the drying temperature and further improving drying efficiency. Compared with traditional direct hot air blowing, this method does not cause the surface of the impregnated paper to vibrate, effectively ensuring the quality of the impregnated paper.

[0026] Working principle and implementation method: First, the device is placed stably by the fixing column 5 of the base 1. The parameters are set by the controller 3. Then, the impregnated paper enters through the first rotating roller 4 on the left and is driven by the second rotating roller 7 driven by the motor 6 on the right. It enters the device from the slots at the left and right ends of the outer shell 8. The heating rod 24 in the oil tank 21 heats the medium through the connecting block 23 and transmits heat to the heating roller 18 through the connecting pipe 22. The threaded coil 19 and high thermal conductivity silicone grease 20 in the heating roller 18 conduct heat. With the help of the non-stick and wear-resistant outer jacket 17, double-sided heating and drying are achieved. During the process, the liquid level sensor 25 and the temperature sensor 26 monitor the oil tank 21 in real time. At the same time, the heating roller 18 is fixed by the mounting bracket 16 and the limiting plate 15. The top cover 9 protects the inside. The rotating door 10 facilitates maintenance. The fan 13 in the fan box 12 accelerates the air flow and regulates the temperature through the heat dissipation hole 14. Finally, the impregnated paper is dried and output from the other end.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
