The invention discloses a resin
powder plasticizing sheet separation device. The resin
powder plasticizing sheet separation device comprises a lower grading cylinder, an upper grading cylinder, a feedpipe, a motor, a transmission shaft and a grading
impeller. The motor is mounted on the upper grading cylinder, the output port of the feed
pipe is arranged under the grading
impeller, the upper grading cylinder is provided with a
discharge port, the transmission shaft extends downward from the upper grading cylinder into the lower grading cylinder, one end of the transmission shaft is connectedwith the output shaft of the motor, and the other end of the transmission shaft is connected with the grading
impeller installed in the lower grading cylinder. The outside of the transmission shaft isconnected with a cooling shaft sleeve in a seal and pivot mode, a
cooling fluid input
pipe and a
cooling fluid output
pipe are installed on the cooling shaft sleeve, and a
cooling fluid channel is arranged between the cooling shaft sleeve and the transmission shaft. The resin
powder plasticizing sheet separation device selects the most reasonable grading wheel taper, grading wheel blade angle andgrading rate by simulating calculation and test of different rotational speeds of grading wheels, grading wheel blades and the grading wheels, low temperature separation is realized, and the formation of new plasticized sheet or
wire drawing phenomenon due to overtemperature contact or friction of resin powder is avoided.
