The guide cylinder 11 is located at the lower right of the second rotating shaft 8, and the guide cylinder 11 is inserted with an extruding piece 12 that can move left and right relative to the guide cylinder 11, and the extruding piece 12 is offset against the push piece 92 Rely, the trigger piece 91 abuts against the protruding post 6, a support 13 is installed on the inner wall on the right side of the box body 3, and a first elastic piece 14 is connected between the support 13 and the trigger piece 91. A connecting plate 15 is installed between the inner wall on the left side of the box body 3 and the guide cylinder 11, the connecting plate 15 is located directly below the feeding port of the feed hopper 2, and the connecting plate 15 is provided with a plurality of first through holes 16.

The waste plastics to be extruded and dehydrated are transported into the hopper 2 through the conveying device, and then fall into the cavity 7 of the first rotating shaft 4, and then start the first motor to drive the rotation of the first rotating shaft 4, and the rotating The first rotating shaft 4 can turn over the waste plastics in the cavity 7, and then drop them into the connecting plate 15. When the first rotating shaft 4 rotates, it will also drive the rotation of the rotating disk 5 and the boss 6. Under the rotation of 6, it will drive the rotation of the trigger 91. After the trigger 91 rotates at a certain angle, the boss 6 and the trigger 91 will be separated. Under the reset action of the first elastic member 14, the trigger 91 and the pusher 92 Rotate in the opposite direction, so that the pusher 92 hits the extrusion piece 12 quickly, and then drives the extrusion piece 12 to quickly hit the plastic on the connecting plate 15. Under the cooperation of the left inner wall of the box body 3, the waste plastic is squeezed out. Press dehydration treatment, the dehydrated water can flow out from the first through hole 16.

During installation, the feed hopper 2 and the first rotating shaft 4 can be installed through a fixing frame (not shown in the figure).

When the cavity 7 on the first rotating shaft 4 was in a vertically upward position, the waste plastics in the feed hopper 2 could drop into the cavity 7, and when the cavity 7 rotated to a vertically downward position, the cavity The waste plastics in the cavity 7 then drop onto the connecting plate 15 .
