This utility model provides a pre-treatment device for recycling printing raw material paper, relating to the field of paper recycling technology. It includes a support frame, a box, and a conveyor frame. A feeding hopper is fixedly installed on the surface of the box, and a discharge pipe is fixedly installed on the lower surface of the box. This utility model uses a starting motor to drive a bidirectional lead screw, causing two baffles to slide synchronously towards or away from each other along a sliding rod under the action of a sliding block. This precisely adjusts the size of the feeding hopper opening, controlling the feeding speed and amount of printing raw material paper, preventing blockage of the crushing roller due to excessive feeding. A flattening mechanism is installed on the conveyor frame, using a hydraulic cylinder to push a moving plate up and down along a guide rod. The moving plate drives the flattening roller to rise and fall, flattening the crushed paper conveyed by the conveyor belt. This effectively removes paper wrinkles and air gaps, preventing jamming or uneven crushing caused by uneven paper during subsequent crushing processes, thus improving overall processing quality and stability.

This utility model relates to the field of electric wire and cable production technology, and in particular to an extrusion coating device for electric wire and cable.
