Air guide assembly of air opening, air nozzle assembly and drying oven

Abstract

The invention relates to the technical field of drying ovens, and discloses an air guide assembly of an air opening, an air nozzle assembly and a drying oven. The air guide assembly of the air openingcomprises at least one air blocking mechanism arranged in the length direction of the air opening, each air blocking mechanism comprises a first surface and two first side faces connected with the first surface, and the two first side faces of each air blocking mechanism are oppositely arranged; and the first surfaces are opposite to the air opening, and one edges, away from the first surface, ofthe two first side faces of each air blocking mechanism are connected to the two long edges of the air opening correspondingly. The air nozzle assembly can effectively reduce the amount of hot air making contact with a blank area, specifically can reduce deformation and wrinkles of the position, in the blank area, of a base material (such as a pole piece foil), improves the situations that the edge, close to the blank area, of a coating layer (an active substance layer on a pole piece) cracks and the like, and then effectively improves the yield of a coating drying product (a battery pole piece).

Description

technical field [0001] The invention relates to the technical field of ovens, in particular to an air guide assembly of a tuyere, an air nozzle assembly and an oven. Background technique [0002] In the field of coating, the blank / coating blank area is generally set according to the needs of the product, that is, the coated uncoated area. For the coating of the battery pole piece, it specifically refers to the area on the foil that is not coated with active materials. The area is generally arranged alternately with the coating area to form a zebra pattern; the existing coating oven air nozzle is evenly distributed along the length of the air nozzle, which will cause some problems in the continuous zebra pattern coating, such as close to the remaining The edge of the coating area in the white area is prone to dry cracking, or the middle area of ​​the coating area is wet and the edge area is dry, etc. At the same time, the blank area is also prone to wrinkles, that is, the bas...

Problems solved by technology

[0004] At present, the conventional shielding method is to use Teflon tape to paste the corresponding position of the oven nozzle to achieve shielding. Although this method has a certain effect, the effect is limited, and the tape is easy to fall off or damaged, and needs to be replaced frequently, so it cannot fundamentally Effectively improve the yield of coated products
