Compression and volume reduction device for infectious waste

The invention is suitable for the technical field of waste treatment, and provides an infectious waste compression and volume reduction device which comprises a box body, a compression cavity, a mounting cavity, a compression plate, a driving mechanism and a feeding unit, and the driving mechanism comprises a driving motor, a rotating disc, a movable rod, a mounting shaft, a reciprocating lead screw, an inner thread sleeve, a pin shaft, a bevel gear and a bevel gear ring. The driving motor is started, the driving motor drives the rotating disc to rotate, the rotating disc drives the reciprocating lead screw on the rotating disc to revolve, the reciprocating lead screw drives the inner threaded sleeve and the pin shaft to revolve, the pin shaft drives the movable rod to move up and down, the movable rod drives the compression plate to move up and down through the mounting shaft, and the compression plate repeatedly compresses waste in the compression cavity for several times. The feeding unit adds waste into t
