The top of vertical puddler 51 is formed with and transversely has the fixed plate 55, installs right angle fixed plate 56 between fixed plate 55 and the vertical puddler 51, and two right angle adjacent sides of right angle fixed plate 56 arrange with fixed plate 55, the laminating of vertical puddler 51 respectively to setting up through right angle fixed plate 56 improves stirring assembly's fastness. The fixing plate 55 is provided with a mounting portion 57 for connecting with the gear ring bearing block 708, so that when the driving assembly drives the screw rotating shaft 703 to rotate, the gear ring bearing block 708 drives the stirring assembly to rotate by taking the screw rotating shaft 703 as an axis.

In the above further embodiment, a densification tray assembly with a corresponding arrangement of the placing hole 201 is arranged below the resting plate 20, and a driver for controlling the densification tray assembly to move up and down is formed in the densification power box 40. The densification cup holder assembly is configured to hold the cup up to a first predetermined height for the filling head 30 to fill the cup with powder or to hold the cup up to a second predetermined height for the pressing head 301 to compact the powder in the cup. The first predetermined height is lower than the second predetermined height.

It should be understood that, when filling head 30 filled the powder in to the cup, the densification support cup subassembly holds up the cup and rises to first preset height, makes the rim of a cup be close to filling head 30 end to make the powder fill to the cup reliably when filling head 30 extruded the powder, reduce because the error of the relative position between filling head 30 and the rim of a cup leads to the powder to spill at the rim of a cup and the rim of a cup outside and cause the filling environment variation. Stop at filling head 30 to the cup filling and need press the real-time to the powder in the filling back cup, the densification holds in the palm the cup subassembly and holds up the cup and rise to the second and predetermine the height, and this second is predetermine highly to be greater than first height of predetermineeing, make filling head 30 terminal press head 301 stretch into to the cup in the powder surface, with through press head 301 flattening reliably and press the cup in the powder, improve the interior powder surface's of cup roughness and increase the density of the interior powder of cup, thereby improve the filling effect of filling head 30 to the interior powder of cup.

It should be noted that, the specific implementation process of the densification cup supporting assembly according to the embodiment that the cup body is lifted to the first preset distance and the cup body is lifted to the second preset distance is well known in the art, and detailed description thereof is omitted.

The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
