HOPPER FOR WASHING COATING MACHINE

WIPO Patent Application WO/2023/187939

A1

The purpose of the present invention is to provide a hopper for washing a coating machine, the hopper being capable of reliably separating air from other components in waste paint and discharging only the air without leakage of waste liquid to the outside. A hopper 21 for washing a coating machine according to the present invention includes a cylindrical body 46 that has an opening 46c at an upper end thereof and an upper lid 24 that covers the opening 46c. The upper lid 24 has an insertion hole 22 through which a rotary atomizing head 30 that is rotatably provided in a coating machine 4 can be inserted into the cylindrical body 46. The hopper 21 further includes a tank-like member 23 outside the cylindrical body 46. The tank-like member 23 has: a cylindrical outer wall portion 41 in which an exhaust hole 43 is formed at an upper section thereof; and a bottom portion 42 an inner surface of which is curved inward. A baffle plate 44 for restricting crawling up of waste paint ejected from the rotary atomizing head 30 is made to protrude from a lower inner surface of the outer wall portion 41 all around the inner surface. Selected drawing: FIG. 2
