Conveniently cleaned powder supplying device

Abstract

The invention provides a conveniently cleaned powder supplying device. The device is characterized by comprising a powder hopper, a powder hopper cover, a fluidization plate, a powder suction pump, a powder transferring pipeline, a pipeline opening and closing control mechanism and a spray gun, wherein the powder suction pump is provided with a pump cavity, and a powder suction port and a powder discharge port which are communicated with the pump cavity, the powder suction port is communicated with a powder outlet of the powder hopper, an atomization pipe is arranged in the powder discharge port, a powder supplying air lead-in port or a cleaning air lead-in port communicated with the pump cavity is formed on the powder suction pump between the powder suction port and the powder discharge port, and an atomization gas lead-in port is formed on the powder suction pump corresponding to the atomization pipe; one end of the powder transferring pipeline is connected with the powder discharge port of the powder suction pump; the pipeline opening and closing control mechanism is used for controlling the opening or closing of the powder transferring pipeline; and the spray gun is connected with the other end of the powder transferring pipeline. The powder suction pump can be cleaned without moving the powder hopper, and the power hopper can realize automatic cleaning.

Description

Technical field: [0001] The invention relates to a convenient cleaning powder supply device. Background technique: [0002] The existing powder supply device, 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, and the powder feeding gas of the powder pump 011 starts to supply air. Under the action of the powder feeding gas, the distance between the powder pump 011 and the spray gun 06 Negative pressure will be formed in the inner cavity, and the powder fluidized by the fluidizing plate 031 in the fluidizing barrel 03 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 this negative pressure; at the same time, the powder pump The atomizing gas supply of 011 can supply the powder to the spray gun 06 to achieve the atomization effect more smoothly. When cl...

AI Technical Summary

Problems solved by technology

[0003] This powder supply device has the following disadvantages: 1) The powder suction pump needs to move the powder hopper 03 when cleaning, which is inconvenient

2) The inside of the powder hopper 03 cannot be cleaned automatically and needs to be cleaned manually

3) The powder outlet pipe 012 of the powder pump 011 is installed in a horizontal position, and the cleaning effect at this section is not good during cleaning

4) New powder needs to be manually added to the powder hopper 03
