For example, when a can is dropped on the first compression region 200 and a PET bottle is dropped on the second compression region 300 , in order to compress a can having a stronger strength, the first compression region 200 . The compression blade 120 and the compression blade guide 130 of the can be made of a relatively strong material, and the compression blade 120, 220 and the compression blade guide 130, 230 depending on the type of can or PET bottle to be compressed. The width of the design can also be flexibly changed.

The diaphragm 140 is fixed at a predetermined position along the longitudinal direction of the rotation shaft 110 , and separates regions in which different types of compression materials are input and compression is performed. That is, the first compression region 200 is formed by the first side plate 150 and the diaphragm 140 , and the second compression region 300 is formed by the second side plate 160 and the diaphragm 140 . do. The relative sizes of the first compression region 200 and the second compression region 300 may be changed according to a position at which the diaphragm 140 is fixed.
