The utility model belongs to the field of
OLED organic light-emitting materials, and particularly relates to an
OLED organic light-emitting material collecting device which comprises a working box, an observation window is fixedly connected in the working box, two glove extending holes are formed in the observation window, the outer side of the working box is fixedly communicated with a
solid-
gas separation device, and the
solid-
gas separation device is fixedly communicated with the working box. And an air injection
assembly is arranged on the outer side of the working box. The sealing elastic cloth is pulled to drive the elastic
rope to stretch so as to extract
mixed gas in the transmission
pipe, then the sealing elastic cloth is loosened to drive the sealing elastic cloth to rapidly rebound through the elastic
rope, so that the
mixed gas enters the working box along the
exhaust pipe, and due to the shape of the
exhaust pipe, the
mixed gas enters the working box through the elastic
rope. By means of the structure, the mixed gas is in a rotating
smoke ring shape, is gradually expanded when leaving the
exhaust pipe and is provided with part of power, and residual materials on the baffle can be struck through the carried power and
dry ice particles, so that the materials are scoured down, and waste of the materials is reduced.
