The invention relates to an automatic quantitative down-filling
machine, which comprises a rack, a table surface, a balance, a down tube, a tube cover, an
elbow, a hose, a down-filling gun and an
automatic control device. The down-filling gun consists of a connecting
pipe, an air
amplifier, an air
amplifier fixing cover, a down-filling
pipe and a down-filling gun
handle, the
automatic control device comprises a down-filling switch, a weighing sensor, a single-
chip microcomputer and a
solenoid valve; the balance is arranged on the table surface, the down tube is supported on the balance by a bracket and is provided with a down-adding port, the hose is connected with the tube cover through the
elbow, an
elbow clamping block is fixed on a crossbeam, the down-filling gun is connected with the hose through the connecting
pipe, the down-filling switch is arranged on the down-filling gun
handle, an air intake pipe connector is connected with the air
amplifier in the down-filling gun, and an air intake pipe penetrates through a hole on the down-filling gun
handle and is connected with the air intake pipe connector. The invention has the advantages that the quantitative weighing and pneumatic filling of down are realized with the
automatic control technology, the down-filing amount can be arbitrarily set, the filling efficiency is high, the
working environment is good, and the down waste and damage can be reduced.
