Description

DETAILED DESCRIPTION OF THE INVENTION <Industry II Field of Application> The present invention relates to a mixer device for crushing and mixing materials to be stirred in a container.

<Prior art> This type of mixer device is configured so that a force/cutter blade is attached to the tip of a rotating shaft and rotated at high speed in a stirring container, and the material to be stirred in the container is crushed and mixed with 10 twists. ing.

<Problem to be Solved by the Invention [飄>] In such a conventional mixer device, the force/interference blade is rotated by a single wooden rotating shaft, so when stirring, the cutter blade moves the material to be stirred in the direction of rotation of the cutter blade. The cutter blade cannot avoid the force that causes a vortex when pressed, so the cutter blade
Since the material to be stirred is chased and mixed in the direction of rotation of the cutter blade, there is a problem in that it is difficult to obtain a stirring effect commensurate with the rotational speed of the cutter blade. 1. This becomes noticeable depending on, for example, friability, viscosity, and concentration.

Means for Solving the Problems> In the mixer device of the present invention, as shown in FIG. This is composed of a shaft 12 and an equicentric shaft 1
Separate cutter blades 20 and 30 are attached to the cylinder shaft 1 and the cylinder shaft 12, respectively.

The core shaft 11 and the cylindrical shaft 12 are rotated at different rotational speeds in a relative relationship, so that the material to be stirred M in the container 40 is crushed and mixed by the plurality of cutter blades 20, 30.

In the device 6 of the present invention, since the plurality of cutter blades rotate at different rotational speeds of 20° and 30°, the material to be agitated M receives the pressing force from the high-speed rotating cutter by the rotation of the low-speed rotating cutter. will be reduced by

Therefore, in the device of the present invention, the vortex velocity of the material to be stirred M is suppressed, or the vortex is further mixed, while the cutter blades of the lower L double-stage cutter blades that rub against each other due to the relative relationship perform crushing and mixing. I will do it.

Embodiment Example 7. The invention mixer device is as shown in FIG.
The rotary shaft body 10 is composed of a plurality of shafts that are concentrically fitted with each other, and cutter blades 20 and 30 are respectively provided at the ends of the shafts.

1- The rotary shaft body 10 has a core shaft 11 located at the center.

It has at least one cylindrical shaft 12 that is heavily fitted to the core i11, and a ball ring 13 is interposed between each shaft.

The rotating shaft IO is supported by a bearing 60 that engages with the support 50, and a pole bearing 61 is interposed between the bearing 60 and the rotating shaft 10.

A main cutter blade 20 is attached to the tip of the L core body 11, and a subordinate cutter blade 3 is attached to the tip of the cylindrical shaft 12.
0 is set.

The slave cuffer blade 30 is attached directly to the cylinder shaft 12.
However, in this embodiment, as shown in FIGS. 2 and 3, the Carter blade 30 is fixed to the lower end of the hollow mounting cylinder 31, and the upper part of the cylinder 31 is connected to the cylinder shaft 12. It is configured to be screwed into the lower end.

For this purpose, the upper part of the mounting cylinder 31 is made into a fitting part, and a female screw 32 is cut into this fitting part.

-1- A cut window 33 is further formed in the -L portion of the mounting tube 31, which allows the mounting shaft 21 of the L cutter blade 20 inserted into the mounting tube 31 to be seen from the outside. I can do it.

-1- The cutter blade 20 may be directly fixed to the lower end of the core shaft 11, but in the embodiment, as shown in FIGS. It is provided at the lower end of the mounting shaft 21, and the mounting shaft 21 is configured to be fitted onto the core shaft ll from below.

For this purpose, the lower part of the J-centering shaft 11 is made to hang down long, and this part is provided with 1 and 2 protrusions.
The upper end of the mounting sleeve 21 is cut out with a substantially-shaped engagement hole 22 that engages with the locking protrusion 111.

In this embodiment, if the mounting shaft 21 of the main cutter blade 20 is externally engaged with the core shaft 11, the mounting shaft 21 will automatically move due to the centrifugal force applied to it when the core shaft 11 rotates at high speed. Since the centering operation is performed, attachment of the main cutter blade 20 becomes extremely easy.

Since this self-alignment of the mounting shaft 21 is performed by displacement of the mounting shaft 21, it is necessary to form a minute gap S between the mounting shaft 21 and the core shaft 11, and to stabilize the j-axis 21. It is preferable to use a die that allows one O-ring 112 to be sunk.

1. The centering shaft 11 and the cylindrical shaft 12 are driven at different rotational speeds in their relative relationship.

This relationship is usually obtained by rotating the cylinder shaft 12 at a low speed while the core shaft 11 is rotated at a high speed.

In this way, the hole bearing 13 interposed between the core shaft 11 and the cylindrical shaft 12 will move around the core shaft 1 by riding on the rotational movement of the cylindrical shaft 12.
It is sufficient to support the rotation of 1, so for example, if the core shaft 1
1 rotation speed is 5o, 000r, p.

mff1, the rotation speed of the cylinder shaft 12 is 20,0OOr, p
, m, the pole bearing 13 is 3
The state is similar to that of supporting a 0.00 Or, p, no core shaft, and there is an advantage that the usage conditions of the pole bearing 13 can be relaxed.

”] The relative relationship between the number of rotations, that is, the rotational speed, between the recording core shaft 1 and the cylinder shaft 12 can be obtained even if the core shaft 11 is set at a lower speed than the cylinder shaft 12. 'I> can be obtained even if the rotation direction of is reversed.

In the embodiment, as described above, the core shaft 11 is configured to rotate at high speed, and for this purpose, the core shaft 11 is provided with a pulley 14, and the cylindrical shaft 12 is provided with a pulley 15. .15 is connected to a drive stage 70, for example, a large diameter drive pulley 71 and a small diameter drive pulley 72 on the motor side.

These drive pulleys 71 and 72 are rotatably attached to a motor drive shaft 73, and this drive shaft 73 is connected to the rotary shaft body 1.
It is constructed such that the number of drive pulleys can be increased or decreased in accordance with the number of core axes and cylinder axes that make up 0.

”- The cylindrical shaft 12 of the rotating shaft body 10 may have a plurality of bottoms,
In this case, there is an advantage that the number of subordinate cutter blades 30 can be increased.

When increasing the number of slave cutter blades 30 in this way, the rotation speed of each slave cutter blade 30 is also relatively changed.
- is desirable, and in this way, the crushing effect of the cutter blade 20.30 that moves up and down can be increased.

Since the mixer device of the present invention is as described above, first attach the secondary canter blade 30 to the tube +112 by attaching the mounting tube 31 to the tube +ll112.
A and fix it, then insert the mounting shaft 21 of the L cutter blade 20 into this mounting cylinder 31 and insert the cutout 3 of the mounting cylinder 31.
1. Attach the cutter blade 20.30 to the rotating shaft body 10 by engaging the engagement hole 22 of the mounting shaft 21 with the L projection ill from step 3. After that, it is sufficient to plunge it into the container 40 and rotate it, and in this way, the material to be stirred M in the container is the main cutter blade 20.1! -Sub-cutter blade 3
0.

<Effects of the Invention> Since the apparatus of the present invention is as described above, it is possible to achieve the following effects.

Since the material to be stirred M is crushed and mixed by the upper and lower cutter blades 20.30, the stirring effect is great.

Since the rotation speed of the multiple cutter blades 20.30 under L is different,
The vortex flow of the stirred material M is subjected to a restraining force, resulting in a complicated mixing vortex flow, which increases the chances of the stirred material M coming into contact with the cutter/blade 20.30, increasing the degree of crushing and mixing.

Since the crushing and mixing conditions for the material to be stirred M can be determined by changing the rotational speed of the ten-canter blade 20 and the subordinate cutter blade 30, it is possible to achieve 2 tL for good stirring and mixing of the material to be stirred.

Since the rotation directions of the L cutter blade 20 and the sub cutter blade 30 are reversed and the two blades intersect, a 2μ is created, so that the fibrous material to be stirred can be crushed and mixed.
