Raw material recovery device in polyester film production process

The invention provides a raw material recovery device in a polyester film production process, the raw material recovery device comprises a raw material crushing box, a stirring motor, a discharge pipe and a feeding hopper, the stirring motor is fixedly mounted at the top of the raw material crushing box, the discharge pipe is communicated to the bottom of one side of the raw material crushing box, and the feeding hopper is communicated to the top of one side, far away from the discharge pipe, of the raw material crushing box. The raw material recycling device can adapt to various forms of raw materials, and can prevent crushed materials from being separated from the crushing box during feeding, so that the problems that adaptive feeding and crushing prevention cannot be performed at the feeding position of an existing raw material recycling device according to different shapes of the raw materials, classified recycling needs to be performed during recycling, personnel expenses are increased invisibly, and the
