Since the first rotating arm 200 is connected to the second rotating arm 300 and the second rotating arm 300 is rotatably connected to the support 100, the second rotating arm 300 will be driven by the first rotating arm 200 to rotate synchronously in the direction away from the powder throwing door. At the same time, the top door 500 is separated from the powder throwing door, and the powder throwing door is opened, and the powder can be introduced into the powder throwing box through the powder throwing port in the powder throwing door. Then immediately rotate the first rotating arm 200 in the opposite direction toward the powder throwing door. The second rotating arm 300 will be driven by the first rotating arm 200 to rotate synchronously toward the powder throwing door. At the same time, the top door 500 rotates to abut against the powder throwing door to close the powder throwing door.

[0036] The powder feeding door blocking device can prevent the powder feeding door from being pushed open by the pressure generated by dust during powder feeding, reduce powder loss and prevent dust from being generated in the production space, ensure that the powder feeding area is clean and not polluted by dust, and ensure product quality.

[0037] Figure 1 A schematic diagram of the powder feeding door blocking device being separated from the powder feeding door so that the powder feeding door is opened; Figure 2 The schematic diagram of the powder throwing door blocking device abutting against the powder throwing door to close the powder throwing door is shown in FIG.

[0038] In an optional manner of this embodiment, a first opening 130 is provided on a side of the support 100 facing away from the powder box, and an end of the second rotating arm 300 extends into the first opening 130 .

The top door member 500 passes through the top door connector 600 and the top pressure section 320, and is fixed by the first fastener 610 and the second fastener 620.

[0051] Please continue to see Figure 3 The top door connecting member 600 is a hollow columnar body and is sleeved on the end of the top pressing section 320. The top door member 500 passes through the hollow part of the top door connecting member 600 and the through hole of the top pressing section 320. A first fastener 610 and a second fastener 620 are arranged between the top door member 500 and the top door connecting member 600 to realize the locking and fixing of the top door member 500.

[0052] Specifically, the top door member 500 is a top door bolt, the through hole is a threaded hole, and the first fastener 610 and the second fastener 620 are nuts. The insertion length of the top door bolt can be adjusted to adapt to Figure 2 In this state, the distance between the second rotating arm 300 and the powder throwing door makes the top door bolt abut against the powder throwing door to close the powder throwing door.

[0053] In an optional manner of this embodiment, the support 100 includes a vertically connected fixing portion 110 and a lead-out portion 120 , the fixing portion 110 is fixedly mounted on the powder box, and the lead-out portion 120 is rotatably connected to the first rotating arm 200 and the second rotating arm 300 .

[0054] See also Figure 1 The fixed portion 110 is fixedly connected to the powder box, the lead-out portion 120 extends vertically toward the outside of the powder box, and the first rotating arm 200 and the second rotating arm 300 are both hingedly connected to the lead-out portion 120 .
