[0020] The present utility model provides a drying device for glass fiber processing, such as Figure 1-3 As shown, the drying device for glass fiber processing includes: an outer box 1 with a drying box 2 fixedly installed; an L-shaped plate 3, the L-shaped plate 3 is sealingly and slidably installed in the drying box 2; an air inlet 4, the air inlet 4 is opened on the L-shaped plate 3; a ventilator 5, the ventilator 5 is fixedly installed outside the drying box 2; an air inlet pipe 6, the air inlet pipe 6 is fixedly installed on the ventilator 5, the air inlet pipe 6 passes through the drying box 2 and is correspondingly arranged with the air inlet 4; a heating mechanism, the heating mechanism is arranged on the ventilator 5 for conveying hot air into the drying box 2; a balancing mechanism, the balancing mechanism is arranged on the drying box 2 for preventing the temperature in the drying box 2 from being too high, and the balancing mechanism is arranged corresponding to the heating mechanism.

[0021] In this embodiment, the outer box 1 serves as the outer shell of the entire drying device, providing a stable environment for the internal drying box 2. The drying box 2 is the core area for drying glass fibers, and the drying process is ensured to proceed smoothly through specific process settings and component configurations. The L-shaped plate 3 is sealed and slidably installed in the drying box 2. This design allows the L-shaped plate 3 to move during the drying process to adjust the air flow and temperature distribution in the drying box. The air inlet 4 is opened on the L-shaped plate 3. When the L-shaped plate moves, the position of the air inlet 4 will change accordingly. The ventilator 5 is fixedly installed next to the drying box 2 outside the outer box 1 as a channel for hot air delivery. The air inlet pipe 6 runs through the drying box 2 and is arranged corresponding to the air inlet 4 to ensure that the hot air can accurately and effectively enter the interior of the drying box. The heating mechanism is arranged on the ventilator 5 for delivering hot air into the drying box 2. The hot air generated by the heating mechanism can quickly increase the temperature in the drying box and accelerate the drying process. The heating mechanism with a high degree of automation can accurately control the temperature and flow of the hot air, thereby ensuring the stability of the drying process and the uniformity of the drying effect. The balancing mechanism is arranged on the drying box 2 to prevent the temperature in the drying box 2 from being too high and to ensure the safety and stability of the drying process.

[0022] In a further preferred embodiment of the utility model, the heating mechanism includes an electronic heating plate 7, a heat dissipation fin 8, a fan 9 and a connecting pipe 10, the electronic heating plate 7 is fixedly mounted on the ventilator 5, the heat dissipation fin 8 is fixedly mounted on the electronic heating plate 7 and arranged in the ventilator 5, the fan 9 is fixedly mounted in the outer box 1, the connecting pipe 10 is fixedly mounted on the output end of the fan 9, the connecting pipe 10 is fixedly connected to the ventilator 5, and the connecting pipe 10 is arranged corresponding to the heat dissipation fin 8.

The electronic heating sheet can generate heat quickly and evenly, providing a stable heat source for the drying process. The heat dissipation fins 8 are fixedly mounted on the electronic heating sheet 7 and arranged in the ventilator 5. The main function of the heat dissipation fins is to increase the heat exchange area and improve the transfer efficiency of heat energy. When the electronic heating sheet 7 generates heat, the heat dissipation fins can quickly dissipate the heat to the surrounding air, and then transport the hot air into the drying box through the ventilator 5. The fan 9 is fixedly mounted in the outer box 1 as a power source to drive the hot air flow.

The function of the cooling fin 11 is to enhance the heat dissipation effect of the cooling end of the electronic heating plate, and quickly dissipate the heat to the environment by increasing the heat dissipation area. The fan 12 is fixedly mounted on the cooling fin 11. The function of the fan is to accelerate the air flow, thereby improving the heat dissipation efficiency of the cooling fin 11. When the temperature in the drying box is too high, the fan 12 will start, drive the air flow, take away the heat on the cooling fin 11, and thus reduce the temperature in the drying box. The curved tube 13 is fixedly mounted on the drying box 2. The curved tube is designed to cool down part of the hot air, thereby achieving temperature balance in the drying box 2 and preventing the temperature in the drying box 2 from overheating.

The hydraulic rod 17 is hinged on the fixing plate 16, and the hydraulic rod 17 is hinged with the sealing door 15. The hydraulic rod 17 is a device that can generate thrust or pulling force, and it realizes the transmission of power through the hydraulic principle. In this embodiment, the hydraulic rod 17 is hinged with the sealing door 15 and the fixing plate 16 respectively, and the sealing door 15 can be conveniently opened or closed by controlling the extension and contraction of the hydraulic rod 17. The user only needs to control the extension and retraction of the hydraulic rod 17 to realize the automatic opening and closing of the sealing door 15 without manual operation, which greatly improves the convenience of use. The thrust or pulling force of the hydraulic rod 17 can be adjusted as needed to ensure that the sealing door 15 can fit tightly against the opening of the drying box 2 when closed, prevent hot air leakage, and avoid safety hazards caused by the sealing door not being closed tightly.

Two one-way plates 18 are hinged on both sides of the air inlet 4, and can be automatically opened or closed according to the wind direction or the flow direction of the airflow. The design of the one-way plate 18 can ensure that air can only enter the drying box from the outside, and prevent the air in the drying box from leaking out. The traction block 19 is fixed on the one-way plate 18 and is located inside the air inlet 4. The function of the traction block 19 is to provide a connection point between the one-way plate 18 and the air inlet 4, which is used to adjust the opening angle of the one-way plate 18 or maintain its stability. The design of the one-way plate 18 can prevent the glass fiber from falling from the air inlet 4 when taking out the glass fiber. The one-way plate 18 can be automatically opened or closed according to the wind direction or the flow direction of the airflow without manual intervention, thereby improving the automation of the equipment.
