Technical Field

[0001] The utility model relates to the field of key production, in particular to a key paint spraying and drying device. Background Art

[0002] During the production process, the buttons need to be painted. A paint sprayer is actually a spraying machine. The operating principle is the same. The paint is dispersed into a mist and sprayed on the surface of the object to be painted. A paint sprayer is a common name for a spraying machine. A car button paint drying device with the publication number CN214917499U is operated by an air pump to facilitate the introduction of external gas into the interior of the air drying box through an air duct. The setting of the heating tube is convenient to increase the gas temperature, thereby improving the air drying effect. Then, the air drying box is used to air dry the buttons on the conveyor belt. However, dust impurities will float in the air. When the paint is not dry, the operation of the air pump will drive the dust impurities in the air to blow on the undried paint surface and adhere to the paint, resulting in impurities remaining on the button surface after the paint is dry. Summary of the invention

[0003] The technical problem to be solved by the utility model is that dust impurities float in the air. When the paint is not dry, the operation of the air pump will drive the dust impurities in the air to blow onto the wet paint surface and adhere to the paint, resulting in impurities remaining on the key surface after the paint is dry.

[0024] The air filter assembly includes a filter box 6 disposed at the upper end of the mounting shell 2 and a fan 7 fixedly disposed at the upper end of the filter box 6. The input end of the fan 7 is connected to an air inlet pipe, and an air outlet pipe 10 matching the output end of the fan 7 is fixedly penetrated through the top surface of the filter box 6. A valved water inlet pipe 15 is disposed on one side of the filter box 6, a first valved water outlet pipe 14 is disposed on one side of the lower end of the filter box 6, and an exhaust pipe 8 connected to the air drying box 9 is disposed on the other side of the filter box 6. By arranging the filter box 6, the fan 7, the air outlet pipe 10, the first valved water outlet pipe 14 and the valved water inlet pipe 15, the wind generated by the fan 7 is washed and filtered by the water in the filter box 6, and then passed into the air drying box 9 again through the exhaust pipe 8, and blown out after being heated and dried by the electric heating pipe, so that the staff can replace the water in the filter box 6, and the operation is relatively convenient.

[0025] A control panel and a temperature controller are respectively provided on one side of the installation shell 2, the temperature controller is electrically connected to the electric heating pipe, and the oil pump 5, the fan 7 and the motor 3 are electrically connected to the control panel respectively, so that the staff can adjust and control the drying device.

[0026] Embodiment 2:

[0027] Further optimization based on the above embodiment: Figure 1-3As shown, a fixed cylinder 12 is fixedly provided on the inner bottom surface of the filter box 6, and the upper end surface of the fixed cylinder 12 is lower than the height of the output end of the valved water inlet pipe 15, and the input end of the first valved water outlet pipe 14 is located outside the fixed cylinder 12, and a second valved water outlet pipe 18 matching with the fixed cylinder 12 is provided at the lower end of the filter box 6, and the lower end surface of the air outlet pipe 10 is lower than the upper end surface of the fixed cylinder 12, and an air guide pipe 11 is provided on one side of the air outlet pipe 10, and the output end of the air guide pipe 11 is located outside the fixed cylinder 12 and lower than the upper end surface of the fixed cylinder 12, and an annular plug 13 matching with the input end of the air guide pipe 11 is slidably provided inside the air outlet pipe 10, and a floating block 17 is slidably provided at the output end of the air outlet pipe 10, and the floating block 17 is fixedly connected to the inner wall of the annular plug 13 through a connecting rod, and an L-shaped limiting rod 16 is provided at the lower end of the annular plug 13. By setting a fixed cylinder 12, two water storage chambers are formed in the filter box 6. By setting components such as an air duct 11, an annular plug 13 and a floating block 17, switching is achieved so that the wind blown out by the fan 7 passes into different water storage chambers. When the staff replaces the water in one of the water storage chambers, the wind blown out by the fan 7 is cleaned and filtered in the other water storage chamber, thereby not affecting the working efficiency of the paint spraying and drying device.

[0028] During use, when it is necessary to replace the water in the fixed cylinder 12, the staff opens the second valved water outlet pipe 18. As the water level in the fixed cylinder 12 drops, the floating block 17 moves downward, thereby blocking the output end of the air outlet pipe 10 by the floating block 17. At this time, the air guide pipe 11 is connected to the air outlet pipe 10, and the wind blown by the fan 7 is discharged into the filter box 6 through the air guide pipe 11. After the sewage in the fixed cylinder 12 is discharged, the staff closes the second valved water outlet pipe 18, and then injects water into the filter box 6 through the valved water inlet pipe 15. At this time, the water overflows the upper end surface of the fixed cylinder 12 and enters the fixed cylinder 12. As the water level in the fixed cylinder 12 rises, the floating block 17 moves upward, thereby driving the annular plug 13 to move upward, so that the air guide pipe 11 and the air outlet pipe 10 are not connected to each other, and the floating block 17 moves upward to open the output end of the air outlet pipe 10, and then the wind blown by the fan 7 is blown into the water in the fixed cylinder 12 for cleaning and filtration.
