The effect of using internal circulation air supply when the outdoor air quality is poor and using external circulation air supply when the outdoor air quality is good is achieved, which greatly enhances the service life of the fan.

[0018] By setting a fixed motor to drive a fixed rotating shaft so that the auxiliary fan is parallel to the ground, the auxiliary fan can be driven to supply air to the coating equipment when the main fan fails, thereby solving the problem that the air supply device cannot supply air to the coating equipment when the fan fails, thereby reducing work efficiency. The effect of temporarily supplying air to the coating equipment through two auxiliary fans when the main fan fails is achieved, which greatly enhances the practicality of the air supply device. The cleaning roller is driven by a cleaning motor, and the moving screw is driven by a moving motor to move the moving seat to the right, so that impurities attached to the surface of the filter plate can be cleaned, solving the problem that impurities contained in the external air entering the air supply device easily cause a large amount of impurities to adhere to the surface of the fan, affecting the service life of the fan, and too many impurities attached to the surface of the filter plate easily prevent outside air from entering. The effect of adsorbing impurities in the outside air entering the air supply device and cleaning impurities on the surface of the filter plate is achieved, which greatly enhances the service life of the fan and the filter plate.

[0019] By setting bolts, the bolts are separated from the limit blocks, and then the limit blocks are separated from the connecting grooves by rotating the handle. After separation, the filter plate can be disassembled, replaced and cleaned, which solves the problem that too many impurities adhere to the surface of the filter plate and it needs to be cleaned or it is inconvenient to disassemble and install when replaced. The filter plate can be directly taken out by rotating the bolts and handles so that the filter plate cannot be fixed during disassembly, and the new filter plate can be fixed by rotating the handles and bolts during installation, which greatly enhances the working efficiency of the operator in cleaning and replacing the filter plate.

The auxiliary motor 13 drives the auxiliary shaft 14 to make the baffle 15 parallel to the ground to block the two air inlets, so that the air inside the coating equipment can be discharged into the inside of the air supply duct 1 through the circulating air duct. The main fan 9 continuously blows air, so that internal circulation air can be supplied to the inside of the coating equipment. , which solves the problem that when the outdoor air quality is poor, continuous air supply to the inside of the coating equipment easily causes a large amount of dust and impurities to adhere to the surface of the fan, thereby affecting the service life of the fan. It achieves the effect of using internal circulation air supply when the outdoor air quality is poor and using external circulation air supply when the outdoor air quality is good, which greatly enhances the service life of the fan. The fixed motor 10 drives the fixed shaft 11 to make the auxiliary fan 12 parallel to the ground. When the main fan 9 fails, the auxiliary fan 12 can be driven to supply air to the coating equipment. After the main fan 9 is repaired, the fixed motor 10 drives the fixed shaft 11 to make the auxiliary fan 12 perpendicular to the ground, and the auxiliary fan 12 is turned off at the same time, which solves the problem that the air supply device cannot supply air to the coating equipment when the fan fails. The problem of reduced working efficiency caused by air supply operation of the equipment is solved.
