The invention discloses a BOPP film production batching device which comprises a batching box, a first servo motor is fixedly installed on the outer wall of the bottom of the batching box, a stirring shaft is fixedly installed at the output end of the first servo motor, and the stirring shaft penetrates through and extends into the batching box. The outer surface of the stirring shaft is fixedly sleeved with a plurality of uniformly distributed fixed lantern rings. A second servo motor works to drive a ball screw to rotate, a ball nut of the ball screw drives a connecting ring and stirring blades located on the outer side of the connecting ring to move upwards, and the stirring blades located on the outer side of the connecting ring drive a plurality of mounting blocks and stirring blades located on the two sides of the mounting blocks to move upwards through arc-shaped connecting pieces; in other words, the multiple stirring blades move up and down while keeping rotating with the stirring rod, so that variou
