The invention discloses a slurry coating device for a battery pole piece in new energy battery production. The device comprises a transmission mechanism, the transmission mechanism is mainly composed of a bottom plate, first vertical plates, second vertical plates, third vertical plates, fourth vertical plates, a discharging roller, a first positioning roller, a second positioning roller, a winding roller and a winding motor, a coating mechanism and a drying mechanism are further arranged between the second vertical plates, the coating mechanism is located above the drying mechanism, and material passing openings are formed in the top and the bottom of the drying mechanism correspondingly. With the device, the pole piece is relatively stable during slurry coating, so that the slurry coating uniformity is facilitated, meanwhile, slurry on the pole piece can be controlled through a fixed scraper and a movable scraper, so that the non-uniformity of the slurry on the pole piece caused by the non-uniformity of the slurry discharged from a movable coating machine head is prevented, and the slurry coating uniformity is further ensured; and when the pole piece is conveyed, the pole piece can pass through a first driving assembly and a second driving assembly conveniently, and thus a large amount of preparation time before production is saved.
