[0016] (1) In the present invention, a pile of plastic sheets are placed on the top of the supporting plate through the feeding holes, and the motor is started. The motor drives the rotating shaft to rotate, and the rotating shaft drives the semicircular block to rotate. During the rotation of the semicircular block, the semicircular block will come into contact with the side wall of the round block. When the straight side of the semicircular block comes into contact with the round block, it is elastically deformed by the second spring. The second spring drives the rotating plate to rotate slightly around the bottom plate. The rotating plate drives the fixed frame to rotate. The fixed frame drives the block to slide along the inner wall of the connecting shell due to the limitation of the connecting shell. The block drives the push rod to move. During the movement of the push rod, the push rod will come into contact with the bottom plastic sheet to push the plastic sheet. At the same time, the rotating shaft drives The driving belt rotates, and the belt drives the first round rod to rotate, and the first round rod drives the first round roller to rotate. During the rotation of the first round roller, the first round roller will come into contact with the moving plastic sheet and be squeezed downward by the second round roller, thereby driving the plastic sheet to automatically load.

Under the reaction force of the plastic sheet, the extrusion plate 583 drives the sliding frame 582 to move upward, and the sliding frame 582 drives the second rotating bar 585 to move upward. When the limiting groove 586 is reached, the second rotating bar 585 drives the connecting block 587 to slide along the inner wall of the limiting groove 586, and the connecting block 587 drives the connecting rod 588 to move, and the connecting rod 588 drives the locking plate 589 to move. During the movement of the locking plate 589, the locking plate 589 will come into contact with the side of the plastic sheet to squeeze most of the plastic sheets, and will not come into contact with the moving plastic sheet at the bottom. Most of the plastic sheets are arranged by the limiting shell 4, so they can be stably stacked, which prevents the movement of the plastic sheets during transportation from causing the two plastic sheets at the bottom to stick together, and the stability of the transportation of the bottom plastic sheets is improved from the side.
