Description

Technical Field

[0001] This utility model relates to the field of impregnated paper production and processing technology, specifically to an impregnated paper hot air circulation drying device. Background Technology

[0002] Impregnated paper drying refers to the rapid drying of impregnated paper using specific equipment to remove surface and internal moisture and improve paper quality. Currently, impregnated paper production requires the use of drying equipment to remove surface or internal moisture. Since hot air and heating pipes are typically used in conjunction with the drying process, the generated hot air is usually directly discharged, resulting in waste of resources. Furthermore, during the drying process, the impregnated paper is usually in a static state, and direct drying of its surface is relatively inefficient, requiring slow evaporation of surface moisture, further reducing drying efficiency and affecting the effectiveness of hot air circulation drying equipment.

[0003] Therefore, it is necessary to develop a hot air circulation drying device for impregnated paper. Utility Model Content

[0004] The purpose of this invention is to provide a hot air circulating drying device for impregnated paper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hot air circulating drying device for impregnated paper, comprising an operating frame, an impregnated paper release roller installed on one side of the top of the operating frame, an impregnated paper take-up roller installed on the other side of the top of the operating frame, a drying box installed at the center of the top of the operating frame, and a cavity installed at the bottom of the operating frame;

[0006] Side panels are installed on both inner walls of the drying oven.

[0007] Preferably, a heating tube is installed at the top of the interior of the drying chamber, and a blower is installed on the top of the drying chamber.

[0008] Preferably, each of the air boxes is equipped with a fan inside, and the upper surface of the air box is provided with a ventilation cover.

[0009] Preferably, a drain outlet is provided at the center of the bottom of the cavity, and air pumps are installed on the upper sides of the outer walls of both sides of the cavity.

[0010] Preferably, the air pump is equipped with an air inlet pipe at its air inlet end, and one end of the air inlet pipe is fixedly connected to one side of the outer wall of the cavity.

[0011] Preferably, the air outlet end of the air pump is equipped with an air outlet pipe, and one end of the air outlet pipe is equipped with an air outlet head, which is located inside the drying oven.

[0012] Preferably, a pressure plate is rotatably connected to the upper part of one side outer wall of the side plate, and a pressure roller is installed on the bottom side of the pressure plate.

[0013] Preferably, a protrusion is installed on the other side of the bottom of the pressure plate, a base plate is installed below one outer wall of the side plate, a motor is installed at the top rear end of the base plate, and an elliptical block is provided on the outer wall of the output shaft of the motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By connecting the air inlet of the vacuum pump on the cavity to the air inlet pipe and the air outlet of the vacuum pump to the air outlet of the drying chamber, the multiple sets of heating tubes on the drying chamber, in conjunction with the fan, can perform hot air drying on the impregnated paper as it is conveyed into the drying chamber by the impregnated paper release roller. During this process, hot air can enter the cavity, be drawn out by the vacuum pump, and then transported into the drying chamber, forming a hot air circulation effect. This avoids the waste of resources caused by direct discharge of hot air during the hot air drying process of the impregnated paper, effectively achieving the effect of hot air circulation drying of the impregnated paper and improving energy efficiency.

[0016] By rotating the pressure plate on the pressure roller to one side of the drying chamber, and setting an elliptical block on the outer wall of the output shaft of the motor, the impregnated paper entering the drying chamber is naturally placed on the surface of the impregnated paper by the pressure roller. The motor drives the elliptical block to rotate, causing the pressure roller to move up and down and touch the surface of the impregnated paper, thus creating a vibration effect. The surface moisture of the impregnated paper can be shaken off through the vibration effect, improving the drying effect of the impregnated paper. This effectively improves the drying efficiency of the impregnated paper and also improves the performance of the hot air circulation drying device for impregnated paper. Attached Figure Description

According to the impregnated paper, the impregnated paper is released from the impregnated paper release roller 101. When the paper is conveyed into the drying chamber 2, the multiple sets of heating tubes 201 on the drying chamber 2, together with the fan 203, can perform hot air drying on the impregnated paper entering the drying chamber 2. During this process, the hot air can enter the cavity 3, and then be extracted by the air pump 302 and conveyed into the drying chamber 2, forming a hot air circulation effect.

Based on the heat generated by the heating tubes 201 after being energized, combined with the blowing of the fans 203, hot air drying can be achieved inside the drying chamber 2. By connecting the air inlet of the suction pump 302 on the cavity 3 to the air inlet pipe 303, and connecting the air outlet pipe 304 on the suction pump 302 to the air outlet 305 on the drying chamber 2, when the impregnated paper is conveyed into the drying chamber 2 by the impregnated paper release roller 101, the multiple sets of heating tubes 201 on the drying chamber 2, in conjunction with the fans 203, can perform hot air drying on the impregnated paper entering the drying chamber 2. During this process, hot air can enter the cavity 3, be drawn by the suction pump 302, and then conveyed into the drying chamber 2, forming hot air. The circulating flow effect minimizes the waste of resources caused by direct discharge during the hot air drying process of impregnated paper, effectively achieving the effect of hot air circulating drying of impregnated paper and improving energy efficiency. By rotating the pressure plate 401 on the pressure roller 402 to one side of the side plate 4 on the drying chamber 2, and setting the outer wall of the output shaft of the motor 405 with an elliptical block 406, the impregnated paper entering the drying chamber 2 is naturally placed on the surface of the impregnated paper by the pressure roller 402. Then, the motor 405 drives and controls the elliptical block 406 to rotate, causing the pressure roller 402 to move up and down and touch the surface of the impregnated paper, thus creating a vibration effect. Through the vibration effect, the surface moisture of the impregnated paper can be shaken off, improving the drying effect of the impregnated paper. This effectively improves the drying efficiency of the impregnated paper and also improves the performance of the hot air circulating drying device for impregnated paper.
