Analysis and test of forward film removing mechanism forpolythene film collector

Film removing is one essential important link in waste plastics film collecting, but the existing removing devices are less reliability or could not clean film up ideally. For the problem, according to SMS-1500 type waste plastics film collector, this paper proposed a new type forward film removing device based on cleaning leaf. Through the analysis on removing mechanism of the device, employing central composite design method, the quadratic regression model between film removing ratio and leaf speed, leaf length, leaf shape was built. The optimal structure parameter of forward removing device was obtained by response surface analysis. Field test indicated that film removing ratio reached 96.3% which proved the feasibility of the device and underlied the following research of related device.
