DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See Figure 1 and Figure 2 As shown, a drying device for aluminum-based copper-clad laminates includes a base 1, a drying box 2 fixed on the base, a conveyor belt 3 passing through the middle of the drying box, and a plurality of electric heating tubes 4 fixed on the inner wall of the drying box; in this embodiment, the above structures are conventional structures of the prior art and are simply applied, so they are not recorded in detail.

[0026] The top wall of the drying box is provided with a cavity 5, the side wall of the drying box is provided with an air guide channel 6 connected to the cavity, and the bottom wall of the drying box is provided with an air outlet hole 7 connected to the air guide channel; at the same time, the outer wall of the drying box is provided with a concave cavity 8 connected to the air guide channel; the concave cavity is provided with a water-absorbing and air-permeable structure 9, and a fan 16 is fixed on the bottom wall of the cavity; in actual application, the interior of the drying box, the fan, the cavity, the air guide channel and the air outlet holes form a circulating air duct. The above structure facilitates the disassembly, assembly and replacement of the water-absorbing and air-permeable structure, which can absorb water vapor in the circulating air duct, thereby ensuring the drying environment inside the drying box, improving the drying efficiency, and being stable and reliable to use, and having strong practicality.

[0027] The water-absorbing and ventilating structure 9 comprises a frame 91, an upper mesh plate 92 fixed in the frame from top to bottom, a glass fiber particle layer 93 and a lower mesh plate 94; the glass fiber is a material with high strength, corrosion resistance and heat resistance, and is commonly used in construction, automobiles, aviation and various chemical equipment. After heating, the surface area of ​​the glass fiber increases, and it absorbs surrounding moisture, thereby increasing its water resistance, so it is often used to make materials with strong water resistance. The upper mesh plate and the lower mesh plate are both metal mesh plates, and during processing, the particle size of the glass fiber particle layer is larger than the aperture of the upper mesh plate and the lower mesh plate.

[0028] In the actual application process, in order to ensure the stability and reliability of the disassembly and assembly of the water-absorbing and ventilating structure, a guide strip groove is provided on the symmetrical inner wall of the concave cavity, and a snap ring groove 10 is provided on the outer surface of the drying box body, and the snap ring groove is located around the opening of the concave cavity; a snap ring 11 is provided on the edge of the outer wall of the frame body; during installation, the symmetrical edge of the frame body is located in the guide strip groove, and the snap ring is snapped into the snap ring groove for sealing. Insertion guidance is performed through the guide strip groove to ensure the stability of the installation position and prevent it from falling or shifting. The snap ring groove cooperates with the snap ring to ensure the sealing of the connection and prevent heat from overflowing. In the actual application process, the thickness of the frame body matches the height of the concave cavity.

[0029] At the same time, in order to prevent the bottom airflow from directly blowing the dried items, a partition 12 is fixed above the air outlet holes; the airflow from the air outlet holes blows toward the bottom surface of the partition and blows into the drying box from the periphery of the partition. A control panel 13 and a temperature display 14 are fixed on the base, and a temperature sensor 15 connected to the temperature display is arranged in the drying box. It is convenient to operate and display the temperature in time.

[0030] The utility model has positive effects: the structure of the utility model is reasonably arranged, and a cavity is provided to cooperate with a fan, an air guide channel and air outlet holes, which can guide the water vapor generated during the drying inside the drying box, and absorb the moisture through the water absorption and ventilation structure, thereby ensuring the dry environment inside the drying box, which is beneficial to improving the drying efficiency and the drying quality, and is also convenient for replacing the water absorption and ventilation structure, thereby improving the convenience of use, and having strong applicability and good practicality.

[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
