Rotating drum for separating flash from plastics mouldings - has bars with shaped ends fitting in trapezoidal slots

摘要

Rotating drum has longitudinal bars attached to end rings which are supported on rollers. The mouldings and flash are fed into one end of the drum and as it rotates the smal pieces of flash and other unwanted fragments fall through the bars whilst the mouldings slide out of the other end of the drum. The bars are secured via trapezoidal slots in the end rings which receive the matching ends of the bars. Elastic rings are positioned at the opposite end of the bars to the inlet opening of the drum.
