Research Status and Prospect of Residual Plastic Film Pickup Mechanism in China

Plastic film mulching technology not only improves the yield, but also brings white pollution. In order to solve the problem of residual film recovery, a large number of plastic film collecting machines have been designed in China. The film picking mechanism is the key part of the residual film recovery machine. Its mechanism form and operation quality play an important role in improving the recovery rate of the residual film. This paper analyzes the development status of the film collecting mechanism of the residual film recycling machine at home and abroad, briefly introduces the structure and working principle of seven kinds of residual film collecting mechanisms, including Winding type, telescopic rod type, elastic tooth type, gear teeth type, drum type and pneumatic type. This study provides relevant suggestions for the optimization and improvement of the film collecting mechanism in the future. (paper)
