After the hose 10 is subjected to outward pulling force, it will gradually extend and stretch. After the micro motor 7 is started, it will drive the discharge block 8 threadedly sleeved therewith to move back and forth inside the discharge frame 5, thereby driving the discharge cover 9 to absorb the odor of the sheet metal paint at different positions on the surface of the transmission roller 2.

[0025] Embodiment 2:

[0026] Based on the first embodiment, Figure 1 and Figure 4 As shown, the bottom end of the L-shaped conveying box 12 is fixedly connected with the top end of the purification box 13, two activated carbon purification cylinders 15 are placed inside the purification box 13, and a sealed box cover 16 is movably installed on the other side of the purification box 13. A large number of circular holes are opened on the surfaces of the two activated carbon purification cylinders 15, and a number of activated carbon particles are filled inside the two activated carbon purification cylinders 15. The utility model is a drying device for sheet metal painting, which is provided with a purification box 13, a sealed box cover 16, an activated carbon purification cylinder 15 and a vacuum pump 14. The odor is discharged to the interior of the purification box 13 through the L-shaped conveying box 12 for purification, and the odorous gas gradually penetrates into the interior through the circular holes opened on the surface of the activated carbon purification cylinder 15.

[0027] Working principle: Sheet metal is a product processed by sheet metal technology. During the processing, a layer of paint will be applied on the surface of the sheet metal to improve the performance of the sheet metal. After the paint is applied, multiple heating rods 4 are needed to dry the paint so that the paint is gradually solidified. The interior of the heating rod 4 is equipped with a heating resistance wire, which is electrically connected to the power switch. After the heating resistance wire works, it will continue to heat, so that the temperature of the area between the drying box 3 and the transmission roller 2 will gradually increase, which will gradually increase the temperature of the surface of the sheet metal, so that the paint on its surface will gradually solidify to achieve the final curing effect. During the drying process of the paint, the odor of the paint will be volatilized, and the odor is relatively large. A large amount of odor will directly spread to the external environment, which has a certain pollution effect. For this reason, the staff can start the micro motor 7 and the vacuum pump 14 at the same time during the drying process of the sheet metal paint. The vacuum pump 14 drives the discharge cover 9 to work. The discharge cover 9 can absorb the odor of the paint volatilized from the surface of the transmission roller 2 into the interior of the discharge block 8, and then transmit it to the soft The inside of the hose 10 is continuously transmitted to the inside of the L-shaped transmission box 12 and the purification box 13. The hose 10 is a foldable corrugated sheet connected along the folding and stretching direction. After the hose 10 is subjected to the outward pulling force, it will gradually stretch and stretch. The hose 10 is made of a bellows. The two are used in the same way. After the micro motor 7 is started, it will drive the discharge block 8 threadedly sleeved therewith to move back and forth inside the discharge frame 5, so it can also drive the discharge cover 9 to absorb the odor of the sheet metal coating at different positions on the surface of the transmission roller 2, increasing the odor collection. The range of collection solves the problem that the odor accumulates in the drying box 3 and cannot be discharged, and improves the comfort of using the drying device. The odor is discharged to the inside of the purification box 13 through the L-shaped transmission box 12 for purification, and the odor gas gradually penetrates into the inside through the circular holes opened on the surface of the activated carbon purification cylinder 15. The odor contacts with a number of activated carbon particles. The activated carbon is made of carbon-based materials and contains a large number of micropores. It can absorb organic pollutants and certain inorganic substances, remove odors, and reduce the pollution degree of odors to the external environment.
