Abstract

The invention relates to an automatic cleaning powder supply device circulating in a closed mode. The automatic cleaning powder supply device comprises a powder supply hopper assembly and an inner core shaft assembly. The powder supply hopper assembly or the inner core shaft assembly is provided with at least two controllable sealing pieces, the powder supply hopper assembly and the inner core shaft assembly carry out relative motion and obtain several different corresponding combination positions through the relative motion, and the controllable sealing pieces seal the powder supply hopper assembly and the inner core shaft assembly at sealing positions on one side and the other side of a set powder absorbing port. Through opening or closing of the controllable sealing pieces, different combinations of a powder channel and a cleaning air channel are formed, and the requirements for powder supply, cleaning of a powder tube or a powder pump or a powder sprayer or other application devices, discharging, cleaning of the inside of the powder supply hopper assembly and manual checking on working conditions are met. Automatic switching between the powder supply channel and the cleaning channel can be achieved, gaps can be adjusted by the controllable sealing pieces conveniently, sealing is reliable, and cleaning is easy, convenient to carry out and thorough.

Description

【Technical field】 [0001] The invention relates to a closed-loop automatic cleaning powder supply device, which belongs to the field of powder transportation. 【Background technique】 [0002] The existing powder supply device with semi-automatic cleaning function, when it is in the powder supply state, such as figure 1 As shown, the lifting mechanism 01 moves downward until the powder suction pipe 02 is inserted into the powder in the powder hopper 03, the powder feeding gas of the powder pump 011 starts to supply air, and the powder pump 011 generates a vacuum under the action of the powder feeding gas, and the fluidization barrel 03 The powder fluidized by the fluidizing plate 031 is transported to the spray gun 06 through the powder suction pipe 02, powder pump 011, and powder outlet pipe 012 under the action of negative pressure; at the same time, the atomizing gas supplied by the powder pump 011 makes the powder achieve the atomization effect Delivery to spray gun 06. W...
