Battery inner core diaphragm spraying device

A battery inner core diaphragm spraying device comprises a supporting plate, a supporting frame, mounting seats, fixing plates, rollers, a motor and a spraying frame, the supporting frame is fixedly mounted on the bottom face of the supporting plate, the mounting seats are symmetrically mounted on the top face of the supporting plate, the rollers are rotatably mounted between the mounting seats, the fixing plates are symmetrically mounted on the side faces of the mounting seats, and the motor is mounted on the fixing plates. According to the battery inner core diaphragm spraying device, through cooperation of the motor and a speed reducer, the rotating speed of a rolling shaft is reduced, diaphragm spraying is more uniform, through cooperation of an air swelling shaft and a locking ring, the rotating speed of the rolling shaft is increased, the rotating speed of the rolling shaft is increased, and the rotating speed of the rolling shaft is increased. According to the diaphragm spraying device, the diaphragm i
