Design of degradable plant fiber tableware trim cutter

An automatic edge trim cutter machine of plant fiber tableware was studied based on designing parameters, technology route and key structure design calculation. The machine was designed with five forming stations driven by air cylinder, planetary gear structure, flexible profile modeling blade edge devices. The edge removing process was done during the turntable revolution and the product's self-rotation. Pro/E software was used to simulate the 3-D entities of trim cutter machine. The working cycle was automatic closed-loop feedback controlled and validated in order to verify the accuracy of the machine. The results show that the trim cutter can be used in plant fiber tableware industry.
