Description

[Detailed description of the invention] [Industrial application field] This invention relates to a liquid mixing device, and in particular, to a liquid mixing device that can mix two or more types of liquids without using a special mixing mechanism. .

[Prior art and its problems]

In general, a liquid mixing device for mixing two or more types of liquids is configured, for example, as shown in FIG. 10, with two tanks 5 for storing liquids.
1 and 52 have discharge holes 53 and 5 at their lower ends, respectively.
4 are provided, and these discharge holes 53, 54
There is a pump 5 in the middle of the pipes 55 and 56 connected to the
7 and 58 are provided, and the pipes 55 and 56 are connected to introduction holes 60 and 61 provided in the mixing section 59, respectively.

The mixing section 59 has a space formed therein, and a mixing member 6 rotatably installed in this space.

However, in the conventional liquid mixing device configured as described above, first, the mixing section 59
A drive source 64 is required to rotate the mixing member 62 disposed inside the unit, and when the mixing unit 59 is stopped for a long time,
For example, if the main agent of the adhesive is stored inside one tank 51 and the curing agent of the adhesive is stored inside the other tank 52, the mixing part 59 should not be cleaned after mixing. If the mixture is left to stand for a while, the mixture will harden and must be cleaned every time it is mixed, making the work extremely complicated.

This invention solves the problems of the conventional ones as mentioned above.Since the mixed material does not accumulate in the mixing section after use, there is no need to clean it after each use. An object of the present invention is to provide a mixing device that can perform mixing using the rotational force of a rotating body when the mixing device is installed on a rotating body even when the mixing device itself is not provided with a driving source. .

[Means for solving problems]

In order to solve the above problems, this invention is a liquid mixing device that mixes multiple types of liquids.
This mixing device includes a plurality of tanks storing different types of liquid, pipes connected to the plurality of tanks and having discharge ends adjacent to each other, and a central portion located below the discharge ends of each of the pipes. It has the shape of a circular tube with its upper and lower surfaces closed, and has a horizontally expanding cavity inside, and has holes on the top surface to receive the liquid falling from the discharge end of each of the pipes, and discharge holes on the sides. The mixing part is formed in the central part of the mixer and is connected to a drive source that rotates in the horizontal direction.

[Effect]

By adopting the above-mentioned means, this idea
By simply dropping multiple types of liquids from inside the tank, these liquids can be reliably mixed, and by simply stopping the liquids from falling, there is no risk of liquid remaining inside. This eliminates the need for work to prevent the liquid from hardening inside.
