On the one hand the powder after moistening is mixed and is compressed again by mediating spiral 16, moistened and do not fill when preventing aforementioned centrifugation
Point, so that mixing is more abundant, extruding auxiliary is provided also by the banded extruder mediated as next step.Preferably, spiral 16 is mediated
End (discharge port side) be provided with reverse acting spiral blade, secondary mixing is carried out by reverse acting spiral blade reverse push animal material,
It is also prevented from material accumulation and enters end bearing.
It further include particle column 19 further, on the inner wall of the shell 1 in further embodiment provided by the invention
It is provided with multiple particle columns 19 arranged along vertical direction, the upper surface of the end of the particle column 19 and the mixing pan 4
It is oppositely arranged, and the end of the particle column 19 is less than 2mm, the effect of particle column 19 at a distance from 4 upper surface of mixing pan
Be particle, since powder may be mixture, there are many, and the size of various powders may be inconsistent, and it is wet after
Powder may lead to occur large scale powder due to mutually sticking, and particle column 19 is connected on the inner wall of mixing chamber 2, by mixing
Disk 4 is centrifuged so that the upper particle column 19 of large scale powder shock, prevents the excessive powder of portion size, as size is greater than 1cm
Powder.
Further, multiple sharp portions are set on the end being oppositely arranged on the particle column 19 with the mixing pan 4,
Such as tiny spine, the effect that sharp portion is arranged is to promote crushing effect.
Further, multiple particle columns 19 are arranged in the different radial positions of the mixing pan 4, multiple particles
Column 19, which is arranged in different radial positions, can block most of or even whole large scale powders, prevent large scale powder quilt
The case where omission.
In further embodiment provided by the invention, further, shell 1 passes through damper mechanism and the powder feeding cylinder
3 are connected, and the nozzle 9 is fixed on the powder feeding cylinder 3, and the effect of such setting is, motor has effect of vibration, shell
The body vibration of body 1 drives nozzle 9 and powder feeding cylinder 3 to vibrate so that powder and liquid be difficult to it is evenly dispersed.Pass through vibration damping machine
The vibration that structure reduces shell 1 passes to the amplitude of powder feeding cylinder 3, so that the dispersion of powder and liquid is more uniform.In general,
Damper mechanism includes damping element such as spring or rubber, and shell 1 and powder feeding cylinder 3 are respectively directly or indirectly and damping element
It is connected, so realizes the effect that the two is connected by damper mechanism.
As shown in Figure 5, it is preferred that damper mechanism includes the first connecting plate 28 and the second connecting plate 29 being oppositely arranged, the
One connecting plate 28 is connected with the second connecting plate 29 by rubber block 30, and the first connecting plate 28 is fixed on the outer wall of powder feeding cylinder 3
On, shell 1 is connected on the second connecting plate 29, and the first connecting plate 28 and rubber block 30 are circular piece, outside the first connecting plate 28
It is placed on powder feeding cylinder 3, rubber block 30 is coated on the first connecting plate 28, so realizes that shell 1 and powder feeding cylinder 3 are direct
Vibration damping.
Further, U-shaped portion, the opening among the end insertion U-shaped portion of shell 1 are provided on the second connecting plate 29
