Description

Technical Field

[0001] The utility model relates to the technical field of metal plate printing, in particular to an air intake structure of a heating chamber of a drying room for metal plate printing. Background Art

[0002] After processing, the metal plate needs to be printed and painted on the surface to prevent the metal plate from aging and rusting during long-term storage and use. After printing is completed, it needs to be passed through a drying room to accelerate the drying efficiency of the paint on the surface of the metal plate.

[0003] As disclosed in the publication (announcement) number: CN118007093A, an air intake structure of a deposition furnace for the production of silicon carbide coatings is disclosed, in order to solve the problem that the thickness of the deposited film at different places on the surface of the part is different, which affects the overall quality of the part. The present invention uses the setting of an air intake chamber and a diversion hole to collect the reaction gas input into the furnace body by the air intake chamber. After that, the gas is discharged onto the carrier through a number of diversion holes. Since the diversion holes are evenly distributed above the carrier, the subsequent reaction gas is more evenly in contact with the parts on the surface of the carrier, thereby improving the uniformity of the deposited film on the surface of the part. By setting the air intake chamber and the stirring rod, the stirring rod is used to disperse the reaction gas in the air intake chamber, so that the amount of gas when the subsequent gas is discharged from the diversion hole is closer to the average amount, thereby making the reaction gas approximately evenly in contact with the parts on the surface of the carrier, thereby improving the uniformity of the deposited film on the surface of the part.

[0004] However, the air intake structure disclosed above cannot adjust the air intake volume according to the use requirements during use, and its application range is relatively narrow. Therefore, it is necessary to propose an air intake structure for the heating chamber of a drying room for metal plate printing. Utility Model Content
