Powder column forming machine

The invention discloses a powder column forming machine which comprises a powder crushing and conveying device, a powder column forming device, a powder column barrel entering device and a powder cup recycling device. The crushing and conveying device conveys powder into the powder column forming device, the powder column forming device compacts the powder in a powder cup, the solid powder cup is input into the powder column barrel entering device through the powder cup recycling device, and then the powder column barrel entering device ejects a powder column into a barrel. And the hollow powder cup enters the powder column forming device through the powder cup recycling device. The powder crushing and conveying device has the beneficial effects that the powder crushing and conveying device can continuously convey crushed powder to the powder forming device, so that a powder cup can be continuously filled with the powder, and a compacted powder column in the powder cup can be pushed into a barrel through the
