Description

[Detailed explanation of the idea] The present invention relates to an improvement in a vacuum shredding mixer.

The conventional shredding mixer is the Japanese Patent Application Laid-open No. 58-45725.
A fixed container type, as shown in Figures 1 and 5 of the publication, and a tilting container type, as shown in Figure 4, are known, but in both cases, the loading position of the raw material into the container is high. Not only is it labor-intensive to input the raw materials manually, and a separate raw material input device such as a conveyor is required, but when taking out the processed raw materials, the discharge position is too low, making it impossible to use a wagon for transporting the raw materials. In addition, there are deficiencies such as difficulty in installing pumps for transporting raw materials.

In addition, the lid requires support when loading and unloading raw materials, and storage space, making handling and storage troublesome. Especially in the case of vacuum mixing containers, the lid is equipped with a vacuum pump connection pipe and stirring blades, which adds weight. However, there are defects that are even more difficult to handle.

The present invention is an attempt to improve these deficiencies.The mixing container and the variable speed motor are mounted on a hanging frame which is rotatably supported on the machine frame by an appropriate power mechanism so that the pivot point is on both sides of the mixing container and the variable speed motor. A rotary cutter shaft that is mounted and supported so as to be located forward in the tilting direction from the center point and rotates inside the mixing container is interlocked with the variable speed motor at the lower part of the hanging frame, and further, the mixing container is sealed in the machine frame. The gist is that a lid body having a vacuum pump connection pipe and a stirring blade is attached to the shaft.

An embodiment of the present invention will be explained with reference to the drawings. On the suspension frame 3 which is suspended between the machine frames 1 and 1' via shafts 2 and 2', there is a lid 4 which is pivoted to the machine frame 1'. The mixing container 5 fitted with the variable speed motor 6 and the variable speed motor 6 are mounted and supported side by side, and in particular, the positions of the shafts 2 and 2' are offset from the center point on both sides of the mixing container 5 and the variable speed motor 6 in the tilting direction. There is.

Further, the mixing container 5 is provided with a rotary cutter shaft 9 on which a cutter 7 is attached via a collar 8, and the rotary cutter shaft 9 is connected to the drive shaft 10 of the variable speed motor 6, the pulleys 11, 12, and the A rotary shaft 15 of a stirring blade 14 rotating on the inner circumferential surface of the mixing container 5 and a vacuum pump connecting pipe 23 are connected to the lid body 4 which is connected via a belt 13 and is pivoted to the co-machine frame 1'. The rotating shaft 15 is formed so as to be rotatable by a variable speed motor 16 for stirring blades provided on the upper part of the lid 4, and the vacuum pump connecting pipe 23 is connected to a vacuum pump to connect the inside of the mixing container 5. It is constructed so that it can be evacuated.

The machine frame 1 is provided with a cylinder 17 for raising and lowering the hanging frame, and its piston rod 18 is connected to an arm rod 19 fixed to the shaft 2 to form the hanging frame 3 so as to be tiltable. Lid lifting cylinder 20
is installed so that the lid body 4 can be opened and closed. In the figure, 21 is a hanging frame stopper, and 22 is a lid tightening tool.

Since the embodiment of the present invention is configured as described above, when inputting raw materials to be shredded or kneaded,
The mixing container 5 is placed in an upright position with the lid 4 open, and then the lid 4 is closed to degas the inside of the mixing container 5, and the raw materials are processed under vacuum using the blades 7 and stirring blades 14. When taking out the raw material, the lid body 4 is opened in an upright state, and the hanging frame 3 is rotated by the hanging frame up/down cylinder 17 to tilt the mixing container 5 and take out the raw material.

In the present invention, a mixing container and a variable speed motor that drives a rotary cutter shaft rotating inside the container are placed and supported side by side, and the shaft support of the hanging frame is shifted from the center of the mixing container in the tilting direction. When the container is upright, that is, the height of the raw material input position is lowered, so that the raw material input operation can be performed easily by hand, and when the mixing container is tilted to discharge raw materials, the lower end of the mouth rim is lowered as much as possible. It is possible to use a wagon for transporting raw materials and install a pump for transporting raw materials, which was previously impossible due to the raised height, and it is possible to smoothly and easily carry out the operation of loading and unloading raw materials in this type of shredding mixer and agitator. Even if the fulcrum shifts in the tilting direction, the rotary cutter shaft can be easily driven by a variable speed motor with a simple interlocking mechanism.

In addition, in this invention, the lid that seals the mixing container is pivoted and held on the machine frame, and only the mixing container can be tilted, so the lid with the vacuum pump connection pipe and stirring blades can be opened and closed when loading and unloading raw materials. It is easy to store, and has excellent features and practicality that allow for efficient and smooth loading and unloading of raw materials in the vacuum shredding mixer.
