Problems to be solved by the invention

However, the stirring and defoaming apparatus sets the rotation number of the container holder and the revolution number of the support base to appropriate rotation numbers according to the type and viscosity of the material to be stirred, respectively, and performs stirring and defoaming. Depending on the combination with the number of revolutions and the increase / decrease in the number of revolutions, the motor may generate vibrations and vibrations that cannot be absorbed by the above-mentioned anti-vibration horizontal mounting plate. There was a drawback that the revolution could not be performed.

In particular, when there is only one horizontal mounting plate for vibration isolation, there is a drawback that the motor is likely to be shaken or vibrated.

Therefore, the present invention appropriately prevents shaking and vibration of the rotary drive machine during the rotation of the container holder and the revolution of the support base, and continuously stirs and degass all types of materials to be stirred under more favorable conditions. It is an object of the present invention to provide an apparatus for stirring and defoaming a material to be stirred.

Means for solving the problem

That is, according to the present invention, a solving means for solving the above-described problems includes a horizontal mounting plate attached to a casing via an elastic body for vibration isolation, and the horizontal mounting plate. A support base that is rotatably attached to the mounting plate, a container holder that is rotatably attached to the support base, a container that is held by the container holder for storing the material to be stirred, and is driven by the horizontal mounting plate In the agitated / defoaming device configured to rotate the container holder via the transmission means and attach the shaft side to the rotation drive for revolving the support base, the other end side of the rotation drive or The midway portion is provided with a vibration isolating means for preventing shaking and vibration of the rotary driving machine during rotation of the container holder and the support base.

Effects and effects of the invention

Next, the operation of the stirring / defoaming apparatus having the above configuration will be described.

A desired stirring material is stored in a container, the container is held in a container holder, the rotation number of the container holder and the revolution number of the support base are set in advance according to the type and viscosity of the stirring material, and then driven to rotate. The machine is driven to revolve the support, and the container holder is rotated through the transmission means.

The rotary drive unit is attached to a horizontal mounting plate that is mounted via an elastic body for vibration isolation, and absorbs vibration generated during driving by the horizontal mounting plate to prevent shaking due to vibration. The support base is also attached to a horizontal mounting plate that is mounted via an elastic body for vibration isolation, and the vibration generated during revolution is absorbed by the horizontal mounting plate and rotated to prevent shaking due to vibration.

However, for example, the combination of the number of rotations and the number of revolutions, or increase / decrease in the number of rotations may cause vibration or vibration that cannot be absorbed by the horizontal mounting plate. Shake and vibration occur around the mounting part.

The vibration and vibration generated in the rotary drive unit prevent proper stirring and defoaming of the material to be stirred in the container.

In this case, since the vibration isolating means provided on the other end side or the middle part of the rotary drive unit is prevented by absorbing the vibration and vibration generated in the rotary drive unit, the rotation of the rotary drive unit is prevented. The drive can be reliably transmitted to the support base and the container holder.

Therefore, an appropriate radial flow and vertical convection are generated in the container, and the contained stirring material is reliably stirred, and bubbles contained in the stirring material are surely degassed by pressing by centrifugal force. be able to.

Further, continuous stirring and defoaming of the material to be stirred can be performed, and the material to be stirred can be appropriately stirred and defoamed under the same conditions regardless of the amount of the material to be stirred.

As described above, the present invention can surely stir and degas correspondingly to materials to be stirred of any kind and viscosity.

In addition, the vibration isolation means can be attached to the other end or midway of the rotary drive according to the shake or vibration generated in the rotary drive, and reliably absorb the generated shake or vibration to eliminate the shake of the rotary drive. Thus, the container holder can rotate and the support table can revolve.

The elastic string 16 made of anti-vibration rubber is continuously stretched in the insertion holes 14A and the cutout holes 13A so that the tension is equal to the lower side of the motor 11 from four directions. 11 absorbs the vibrations and vibrations generated in

The anti-vibration rubber has a damping effect unlike a metal spring, and can reduce the resonance magnification, so that it is suitable as an anti-vibration means in the stirring / defoaming apparatus.

The attachment position of the connecting frame 15 to the motor 11 is determined according to the shape, size, vibration, and vibration of the motor 11. For example, the connection frame 15 can be attached to the middle portion of the motor 11.
