Problems solved by technology

[0003] (1) In order to make the wind force of the tuyere sufficient to support the pole piece and suspend the pole piece in the drying room, it is necessary to reduce the tuyere of the tuyere to make the wind force more concentrated. When the pole piece is subjected to excessive wind force, the pole piece will The coated slurry is easy to be blown away, resulting in uneven distribution of the pole piece coating, which affects the quality of the pole piece; at the same time, there is also the problem of unstable operation of the pole piece
[0004] (2) The lifting structure of the upper air nozzle is not designed, and the lifting of the upper air nozzle is still controlled by manually adjusting the 4 screws. Since the oven of the coating machine is very long (more than ten meters), manual adjustment is time-consuming and laborious, and it is easy to cause Box deformation
[0005] (3) Due to the large air volume required by the suspension type, the air pressure in the drying room is high, and there are potential safety hazards

Abstract

The invention discloses an oven of a coating machine. The oven is characterized by comprising a feeding-end auxiliary oven, a discharging-end auxiliary oven and a main oven positioned between the feeding-end auxiliary oven and the discharging-end auxiliary oven, wherein both the feeding-end auxiliary oven and the discharging-end auxiliary oven are floating-roller supporting type ovens; and the main oven is a suspension type oven. The oven has the benefits of high coating efficiency and good coating quality.

Description

technical field [0001] The invention relates to a pole piece coating technology, in particular to an oven for a coating machine. Background technique [0002] The pole pieces of lithium-ion batteries are formed by coating the slurry on the base material (copper foil or aluminum foil) and then drying. The oven of the coating machine is used for drying the pole pieces. The pole piece is conveyed by the roller, and the upper air nozzle is controlled by manually adjusting the 4 screws. The Chinese patent No. 201010116483.3 discloses a suspension coating machine oven, which includes the main body of the oven (the inner and outer tanks of the oven, the oven door, and the oven frame), a ship-shaped independent air inlet chamber, an improved air nozzle, a drying chamber, and an exhaust chamber , circulating air chamber, circulating air duct, blower, heating device, etc. It is characterized in that the wind force inside the coating machine oven is used to support the suspended struc...
