Thus, when the hopper assembly 241 moves up and down, the dust-proof sleeve 2311 moves up and down in the dust-proof space 2410 relative to the dust-proof cap 2419 and the hopper rotating shaft 2412, so that the gap between the hopper rotating shaft 2412 and the rotary longitudinal sealing seat 231 can be closed, and the dust is prevented from falling from the gap to corrode equipment and damage the equipment.

In this embodiment, the dust sleeve 2311 is, but not limited to, a stainless steel sleeve, and the bottom end of the dust sleeve 2311 is removably fixed to the rotary longitudinal seal holder 231 by a fastener.

The powder packaging machine provided by the embodiment comprises the material receiving and filling device 240, so that the material receiving and filling device 240 is adopted, the packaging efficiency can be improved, and the production cost is reduced.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
