Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to foods, in particular, mixing warm rice and ingredients in mixed rice, and other foods.
The present invention relates to a mixer used for mixing powders and granules, which are raw materials for medicines, ceramic products and the like.

[0002]

2. Description of the Related Art Conventionally, as a mixer used for mixing raw materials such as foods, pharmaceuticals, ceramic products, etc., a mixing container for putting articles to be mixed is rotated around its central axis, and mixing is performed. The two revolutions of the revolution revolving on the axis orthogonal to the central axis of the container were combined to perform three-dimensional rotation to mix the inputs in the mixing container.

Since this mixing machine is configured to rotate the mixing container supported in the rotating cage and to revolve the rotating cage together with the mixing container, the mixing container is placed in the rotating cage. It was limited in size and shape that could be rotatably supported by, and the mixing container could not be replaced for changing the amount of the material charged into the mixing container or for changing the shape of the container according to the material of the material.

In addition, the mixing container is designed to stabilize the revolution.
A revolution shaft is arranged corresponding to the central portion of the mixing container orthogonal to the rotation shaft, and both ends of the revolution shaft are rotatably supported.
Therefore, the rotating and revolving mechanical parts are installed in the outer periphery of the central part of the mixing container in an exposed state, and foreign matter and cleaning liquid enter the mechanical parts during use and cleaning of the mixer, resulting in failure of the mechanical parts. In addition, since both ends of the revolution shaft must be supported as described above, the support frames are arranged on both sides of the mixing container, the mixer itself becomes large, and the installation space must be secured. There wasn't.

Regarding the rotation drive of the mixing container, the driving roller is pressed against a rotating ring fixed to the outer periphery of the mixing container, and the mixing container is rotated by friction transmission to the rotating ring by the driving roller. Since it is a configuration, due to long-term use, the pressure contact portion of the rotation ring and the drive roller is extremely worn, the desired rotation force is not transmitted, and the rotation performance is deteriorated. It was necessary to adjust the degree of pressure contact or to replace the rotating ring and the drive roller, and such adjustment and replacement work required labor, time, and was extremely troublesome.

In particular, when the drive roller is pressed against the rotating ring of the mixing container, the pressure contact does not hinder the rotation of the rotation shaft, and the position of the drive roller must be finely adjusted.
When the mixing container is rotated, a load is applied to the rotating shaft, stable rotation of the mixing container cannot be obtained, and there is a drawback that causes a malfunction of the mixer.

[0007] Also, by the mixing container that rotates and revolves,
Since the input material collides against the inner wall surface of the mixing container and is merely stirred and mixed, the mixing efficiency is poor and the rotation time of the mixing container cannot be shortened.

[0008]

SUMMARY OF THE INVENTION The present invention makes it possible to replace a mixing container regardless of its size and shape, prevent foreign matter from entering the drive mechanism of the mixing container, and rotate the mixing container by a drive roller. It is an object of the present invention to provide a mixer that can be rotated by a transmission means that does not rely on frictional transmission, that is, the size of the mixer can be reduced, and that mixing efficiency can be improved.

[0009]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned prior art, and the size and shape of the mixing container are limitedly used, foreign matter is invaded by the exposure of the drive mechanism, and the rotation performance of the mixing container is deteriorated by the friction transmission means. In view of the problems of increasing the size of the mixer and inefficient mixing of inputs, the cylindrical revolution drive shaft and the rotation drive shaft rotatably inserted in the revolution drive shaft are connected to separate drive sources. , The rotary drive shaft and the mixing container are connected to the rotating frame, which is formed by coating the transmission mechanism, and fixed to the revolution drive shaft, and the mixing container and the balance weights are arranged at both ends of the rotating frame. , The center axis of which is the axis of rotation, is arranged on the line of intersection with the revolution drive shaft, and the end of the mixing container is rotatably supported in the rotating frame. The size and shape of the mixing container can be replaced by supporting the end of the mixing container, the mixing container can be replaced regardless of these conditions, and the mixing container can be cantilevered by the revolution drive shaft to reduce the size of the mixing machine. At the same time, the transmission mechanism is covered with a rotating frame to prevent foreign matter from entering, and the end of the mixing container is rotated by a bearing that can be used permanently for stable rotation without friction transmission means. Enable and
Further, the above-mentioned drawbacks are not solved by disposing stirring blades in the mixing container to improve the mixing efficiency.
