APPARATUS FOR GRINDING AND CRUSHING OF PET CONTAINERS

The present invention relates to a crushing apparatus dedicated to pet containers. The crushing apparatus dedicated to pet containers comprises: a crushing unit; and a power unit. The crushing unit comprises: a driving cutter unit including a driving shaft connected to the power unit and rotationally driven and a driving cutter in which a plurality of unit objects are arranged at regular intervals and fixedly coupled to the driving shaft; a driven cutter unit including a driven shaft positioned on one side of the driving shaft, arranged in parallel with the driving shaft, and installed to be relatively rotated by being gear-coupled to the driving shaft, and a driven cutter in which a plurality of unit objects are arranged at regular intervals and fixedly coupled to the driven shaft; and a cleaning cutter unit including a cleaning shaft positioned on the other side of the driving shaft, arranged in parallel with the driving shaft, connected to the driving shaft by chain or belt coupling, and installed to rotate in the same direction as the driving cutter unit and a cleaning cutter in which a plurality of unit objects are arranged at regular intervals and fixedly coupled to the cleaning shaft. According to the present invention, the crushing apparatus dedicated to pet containers is advantageous of: crushing pet containers in the form of flakes with a size of about 10 mm, which can be directly extruded without going through a secondary grinding process through the crushing unit having an improved structure; increasing efficiency in introducing and crushing pet containers; and being configured as a low-speed grinder implemented by using a general commercial voltage and implemented with low noise so as to be installed and used in an area close to a life such as an apartment, a government office, a hospital, a research institute, a café, and the like, thereby being installed and used anywhere without any spatial constraints. 본 발명은 페트용기 전용 파분쇄기에 관한 것으로서, 동력부에 연결되어 회전 구동되는 구동축과, 상기 구동축 상에 단위개체 다수가 간격 배열되어 고정 결합되는 구동커터로 이루어진 구동커터부; 상기 구동축의 일측에 위치하여 평행 배열되고 구동축과 기어 결합에 의해 상대 회전하게 설치되는 피동축과, 상기 피동축 상에 단위개체 다수가 간격 배열되어 고정 결합되는 피동커터로 이루어진 피동커터부; 상기 구동축의 타측에 위치하여 평행 배열되고 구동축과 체인 또는 벨트 결합에 의해 연결되어 구동커터부와 동일한 방향으로 회전하게 설치되는 클리닝축과, 상기 클리닝축 상에 단위개체 다수가 간격 배열되어 고정 결합되는 클리닝커터로 이루어진 클리닝커터부;를 포함하는 파분쇄부를 갖는 것을 특징으로 한다. 본 발명에 따르면, 구조 개선을 갖는 파분쇄부를 통해 리그라인딩(regrinding)의 2차 분쇄 공정을 거치지 않고 압출성형이 바로 가능한 10mm 내외의 플레이크(flake) 형태로 페트용기를 파분쇄할 수 있고, 페트용기의 투입효율 및 파분쇄 처리효율을 높일 수 있으며, 일반적인 상용전
