Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for uniformly mixing two or more types of powders, granules, pastes, or liquids in a short time.

Various tools such as stirring rods, mixers, and kneaders are used to mix two or more types of powders, granules, pastes, or liquids, but sometimes the mixing at the bottom of the container is insufficient. There are many cases. In particular, in the case of a pasty material such as a printing paste used for dyeing, it is difficult to achieve uniform mixing because it sticks to the vessel wall.

In the textile printing industry, a mass production method was established from a batch method to a continuous method, and there was a big leap from a labor-intensive industry to an equipment industry. In order to perform high-mix, low-volume textile printing using mechanical equipment, a large number of printing pastes compatible with this have become necessary.

The printing paste manufacturing process first involves using different types of adhesives (seafood-based adhesives,
A starch-based sizing agent, a gum-based sizing agent, a cellulose derivative-based sizing agent, a synthetic sizing agent) are blended and mixed using a horizontal mixing device equipped with a stirring screw to create a base glue. Next, the base paste, dye, auxiliary chemicals (softening agent, dye solubilizer, antifoaming agent, dispersant, etc.), water, etc. are sequentially added to the container and mixed.

The mixing method is when the weight of the printing paste used is about 30:9, put a hand mixer in the container and stir and mix.
If the mixture is too thick, mix with a hand mixer and then use a wooden paddle to mix. When it is about 9 out of 150, the glue stirred using a wooden paddle as described above is placed in a bladed stirrer and further mixed.

In either case, mixing takes place at the center of the container, so
Uniform mixing on the inner wall and bottom of the container is difficult, especially when the glue is highly viscous, and poorly mixed glue sticks to the inner wall of the container or stays on the bottom, resulting in poor overall performance. This results in a very uneven printing paste.

If such a printing paste is used, it will clog during the printing process and cause a speck of "v/+"1, making it impossible to obtain a high-quality printed product. In addition, in response to the high-mix, low-volume production system,
Another problem is that a large number of hand mixers and the like must be provided.

A hand mixer weighs about 5 kg, so it is heavy to operate by hand, and requires skill to use.
If used incorrectly, there are problems and dangers such as the printing paste flying out of the container, the container tipping over, and the user being thrown around by the hand mixer. Wooden paddles also have the disadvantage of being very labor intensive.

As described above, conventional tools and machines are no longer able to meet the demand for high-mix, low-volume production that requires a wide variety of printing pastes, and we have developed a method to manufacture printing pastes that are labor-saving and uniformly mixed. The development of this technology has become necessary.

The present invention satisfies the above-mentioned needs and aims to provide a method and apparatus for producing uniform printing paste, etc. without uneven mixing in a short time, safely, and without requiring any skill.

Next, the configuration of the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram of a bowl-shaped container (2) and a part for starting the container according to an example of the present invention, and FIG.
) and the part that starts it.

The first invention relates to a method in which a bladed stirrer (1) applies rotational motion, swirling motion, and pressing action to a material to be mixed consisting of two or more types of powder, granules, paste, or liquid. At the same time, this is a method of uniformly mixing the materials to be mixed by applying a wave-shaped rotational motion using a rotating bowl-shaped container (2) whose peripheral portion moves up and down in a wave-like manner.

In the method of the present invention, the materials to be mixed at position A in FIG. It moves outward as a flow, and at position C, when the stirring blade (7) descends, it is rotated and pressed against the bottom surface, and when the stirring blade (7) rises, it is pulled up while rotating and kneaded. will be combined.

The movement at position D is that the bowl-shaped container (2) vertically rotates in a waveform, and since the bowl-shaped container (2) has a bowl-shaped shape, the bowl-shaped container (2) repeats a downward collision with the wall surface and an upward collision, and eventually moves toward the center. do.

In addition, accumulation and adhesion do not occur on the inner wall and bottom circumference of the bowl-shaped container (2).

In this way, due to the combined motion of the vertical and rotational motion of the stirring blade (7) and the waveform rotational motion of the bowl-shaped container (2), the materials to be mixed undergo complicated movements such as rotation, swirl, collision, and waveform elevating and pressing. Since it is subjected to motion, uniform mixing can be achieved in a short time.

The second invention is an invention of an apparatus used in the first invention, and the figure is an example of its implementation.

A corrugated activation board (3) having a corrugated circular guide groove (4) is fixed on the appropriate leg. Above it is a corrugated rotary disk (6) on which the bowl-shaped container (2) containing the materials to be mixed is placed. A guide wheel (1) that fits and rolls to make a wave-shaped circular motion.
1) at the tip, and a guide device (5) having a coil spring for alleviating the vibration of the corrugated rotary disk (6) is fixed thereto. Further, a T-shaped rotating shaft (9) that passes through the center of the wave-shaped starting plate (3) and is rotated by a power source (not shown) is connected to the center of the wave-shaped rotating plate (6) via a rotation transmission ring 00). It is fixed.

Therefore, the rotation of the T-shaped rotating shaft (9) causes the corrugated rotary disk (6) to rotate, but at the same time, the guide device (5) rotates around the T-shaped rotating shaft (9), and the guide wheel C11l rotates according to the rotation. Because it moves up and down in a waveform, it ends up being a waveform rotary disk (
6) rotates while the peripheral part moves up and down in a waveform.

Since the bowl-shaped container (2) is fixed to the corrugated rotary disk (6) by means such as a hook, it moves in the same manner as the corrugated rotary disk (6). The corrugated rotary disk (6) rotates while being inclined, and the rotary transmission ring (10) functions to smoothly perform the inclined rotation.

The stirrer with blades (1) consists of a stirring blade (7) and a motor (12) directly connected to the shaft.
6) is located in the center of the bowl-shaped container (2) placed on the container.

The bladed stirrer (1) is moved up and down by a stirrer lifting device (8).

An example of the stirrer lifting device (8) is shown in Fig. 2, in which the bladed stirrer (1) is mounted on a support rod (one vertically mounted and a sliding mechanism provided at the end of the support rod (13)). A support post 4 is fitted into the hole, and the support rod (13) is guided by the support post (14) and can move up and down.

On the other hand, a rotating disk (1
A motion converting rod 06) is mounted on the eccentric position 5) and the end of the support rod (13). Now, when the rotary disk (15) rotates, the motion conversion rod (1δ) converts the rotational motion into vertical motion and transmits it to the support rod (13), and the support rod (13) moves up and down. Therefore, the stirring blades (7) of the bladed stirrer (1) move up and down within the bowl-shaped container (2).

Since the configuration is as described above, the peripheral part of the bowl-shaped container (2) moves up and down in a waveform while rotating, and the stirring blade (7) inside the bowl-shaped container (2) moves up and down in the bowl-shaped container (2). It will rotate while moving up and down.

The above-mentioned configuration is one example, and basically consists of stirring blades (7
) rotates the bowl-shaped container (2) while moving up and down, the bowl-shaped container (2) is placed on the corrugated rotary disk (6), and the corrugated rotary disk (
6) has a guide device (5) that fits and slides into the wave-shaped circular guide groove (4) or guide protrusion of the wave-shaped activation board (3), and is configured to rotate by being attached to the rotating shaft. If so, various detailed configurations may be adopted.

For example, instead of the guide wheel (111), a rod-shaped guide rod that fits and slides in the guide groove (4) or a rod-shaped guide rod that has a groove that fits in the guide protrusion may be used, and the T-shaped rotating shaft (9) The rotating shaft and the corrugated rotary disk (6) can be engaged with each other by pivoting between the hemispherical end of the rotary shaft and the hemispherical recess in the center of the corrugated rotary disk (6). It's okay.

The configuration of the stirrer lifting device (8) may also be such that, for example, the bladed stirrer (1) is vertically mounted on a motion converting rod (16) provided above the bladed stirrer (1). It does not have to be directly connected to the motor (12) as described above, but may be rotated by a belt.

Regarding the materials to be mixed, although the explanation has mainly been about printing paste, it is also possible to mix or knead two or more types of various powders, granules, pastes, or liquids, such as mixing confectionery materials, preparing paints, It can be used for a wide range of purposes, including mixing drugs.

When, for example, a printing paste is manufactured by the method of the invention using the apparatus of the invention, the bowl-shaped container (2) is removed and held as the first color printing paste, and another bowl-shaped container (2) is placed. Then, the second color material is added, mixed and retained as the second color printing paste.

Hereinafter, printing pastes of multiple colors can be sequentially produced in multiple bowl-shaped containers (2) using one device.

Since the present invention has the above-mentioned configuration, regardless of whether the materials to be mixed are powder, granules, paste, or liquid,
In the bowl-shaped container (2), a combination of rotation/swirling motion, wave-shaped rotation motion, suppression, and collision occurs, and the mixture is easily and uniformly produced in a short time without requiring operator skill. It has a remarkable effect of being able to produce a mixture at a low cost, and is particularly effective in producing a mixture suitable for high-mix, low-volume production, such as printing paste.
