The PET bottle can be classified into a body, a lid, and a label composed of PP (Polypropylene), PE (polyethylene), and PET (polyethylene terephthalate), and further, the body has a relatively soft body and a strength It can be divided into pads to increase the material. The container body is mainly made of PET, the lid is made of PP or PE, and the label is made of PE, PP, PC, PS, or PET shrink film. In order to recycle PET bottles made of various materials, it is necessary to separate them by material. The specific gravity of the constituent material is 1.3, the PS is 1.05-1.1, the PP, or the PE is 0.95, and the specific gravity of the material is 1.3, PS is 1.05-1.1, and the specific gravity , And the specific gravity treatment method is used to separate the materials by the difference between them.

Open No. 2000-0072851 discloses a PET bottle recovery and recovery method. PET bottles are collected and classified according to colors. Then, PET bottles of the same color are simultaneously pulverized to produce pulverized materials composed of various materials having a predetermined size, Separate the PET crushed material with high specific gravity and the PP or PE crushed material with low specific gravity by using the treatment device. 1, when the water tank 1 is filled with water and a pulverized product containing PET, PP, PE, or the like is fed from one side thereof, the PET pulverized product having a specific gravity larger than 1, The PP or PE pulverized material falling downward and having a specific gravity smaller than 1 is configured to be collected through the one side discharge port 4 by the transfer of the rotary vane 2 in a floating state on the water surface, Is conveyed to the next process by the screw (6). The PET pulverized material sorted and separated by the specific gravity treatment method is then charged into a solvent dissolving tank and stirred to obtain pure PET pulverized material. However, according to the conventional specific gravity treatment method, since the specific gravity is not less than 1, such as the PS film or the PET shrink film, there is a problem that the material to be sorted is classified into the same group as the PET pulverized material, And the PET cleaning process are separated from each other, the space occupied by the equipment is widened, and the process time is prolonged due to the two processes. In addition, there was a problem that a separate washing process was required to recycle the PE pulverized product of the PP peat.

On the other hand, Japanese Patent Registration No. 10-0548502 discloses a PET bottle cutter capable of uniformly cutting PET bottles to a desired size in a short time to produce pulverized PET bottles.
