Description

Tuyere device, oven equipment and battery production system Technical Field The application relates to the technical field of drying equipment, in particular to a tuyere device, drying oven equipment and a battery production system. Background In the production process of the battery, the slurry is coated on the surface of a substrate, and then baked by an oven tuyere to form the pole piece. In the baking process, the area of the base material, which is not coated with the sizing agent, is easier to be dried than the area of the base material, which is coated with the sizing agent, because the weight is lighter and the thickness is thinner, so that the membrane is deformed to form cracking in the process of heat shrinkage, and the forming quality of the pole piece is directly affected. Disclosure of utility model In view of the problems, the application provides a tuyere device, oven equipment and a battery production system, which are beneficial to improving the forming quality of pole pieces. The application provides a tuyere device which comprises a tuyere body, a shielding piece and a driving assembly, wherein the tuyere body comprises a first wall, the first wall is provided with a plurality of air outlets, the shielding piece is arranged on one side, away from the inside of the tuyere body, of the first wall along the thickness direction of the first wall, the driving assembly is arranged on the tuyere body and comprises a driving piece and a guiding piece, the shielding piece is connected to the guiding piece, and the driving piece is configured to drive the guiding piece to move along the length direction of the first wall relative to the first wall so that the shielding piece can shield part of the air outlets. In some embodiments of the first aspect, the position of the shielding member is adjusted by the driving member, so that the shielding member can shield the air outlet opposite to the area of the substrate, which is not coated with the slurry, so as to block the air flow blown out from the air outlet, reduce the drying rate of the area of the substrate, which is not coated with the slurry, and improve the problem that the area is easy to crack, and facilitate improving the molding quality of the pole piece.
