When the powder reaches the height of the powder sensor 9, the powder sensor 10 outputs an electrical signal to the controller 6, and the controller 6 closes the powder pump 2, thereby realizing automatic feeding. The air outlet valve 8 can discharge the excess gas in the feed hopper 5, and the powder filter cloth 7 can prevent the powder from being discharged along with the gas. Since the device is automatically fed, the feed hopper 5 is a closed structure, which greatly reduces the dust generated during the manual feeding process. Through the above structure, the device can automatically feed and prevent dust from being generated during the feeding process, which is conducive to improving the practicality of the device.

[0026] like Figure 1 and Figure 3 As shown, the end of the feed pipe 4 is connected to the feed hopper 5, and the powder pump 2, the powder sensor 1 9 and the powder sensor 2 10 are all electrically connected to the feed pipe 4.
