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

Embodiment Construction
[0034] As shown in the figure, an easy-to-clean powder supply device includes powder hopper 1, powder hopper cover 2, fluidization plate 11, powder suction pump 3, powder delivery pipeline 4, pipeline opening and closing control mechanism 5, and spray gun 6.
[0035] The powder hopper 1 is open at the upper end and closed at the bottom end, and has a cavity for holding powder 10. The bottom of the powder hopper 1 is provided with a gas inlet 12, and the bottom of the powder hopper 1 is also provided with a powder unloading port 13 for unloading. The powder port 13 is connected with an external powder discharge shrink valve 14.
[0036] The powder hopper cover 2 is in a sealed fit with the upper end opening of the powder hopper 1, and the powder hopper cover 2 is provided with a cleaning gas inlet (not shown in the figure) communicating with the cavity of the powder hopper. The set cleaning shrink valve 21 is connected. The powder hopper cover 2 is also provided with a powder reco...

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 powder supply device which is convenient for cleaning. Background technique: [0002] The existing powder supply device, when in the powder supply state, such as figure 1 As shown, the lifting mechanism 01 moves downwards until the powder suction tube 02 is inserted into the powder of 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 fluidized barrel 03 will be transported to the spray gun 06 through the powder suction pipe 02, the powder pump 011, and the powder discharge pipe 012 under the action of this negative pressure; at the same time, the powder pump The atomization gas supply of 011 makes the powder reach the atomization effect and supply the spray gun 06 more s...
