The utility model discloses a pole piece double-sided coating mechanism for high-efficiency production of new energy batteries, which comprises a box body, support legs are fixedly mounted at the bottom of the box body, a storage tank is communicated with the outer wall of the box body, a pole piece base material is arranged in the box body, when the pole piece base material needs to be coated, the pole piece base material needs to be in a flat state, and when the pole piece base material needs to be coated, the storage tank is communicated with the storage tank. The pole piece base material is placed on the inner sides of the two pressing rollers, telescopic rods are started, the telescopic rods push sliding plates fixedly installed at the ends of the telescopic rods in the direction away from the guide rollers, and sliding blocks fixedly installed on the outer walls of the sliding plates slide in sliding grooves formed in the inner wall of the box body; the inner wall of an inclined groove formed in the outer wall of the sliding plate makes contact with and extrudes the outer wall of the sliding column, the sliding column drives the pressing rollers to slide in the limiting frame so that the distance between the pressing rollers can be adjusted, the pressing rollers can be close to the pole piece base material, and when the pressing rollers make contact with the outer wall of the pole piece base material, the telescopic rod stops working, and coating work can be conducted on the pole piece base material.
