Description

[Detailed Description of the Invention] (Field of the Invention) This invention relates to a kneading device for colorants such as paints, dyes, and pigments.

(Prior Art) The kneading device for colorants that has been commonly used in the past is a stirrer, a tumbler, or the like. Therefore, it takes a long time to knead extremely viscous materials or granular raw materials that are difficult to dissolve, and even then, a sufficient kneading effect cannot be expected.

(Purpose of the invention) This invention is designed to
Another object of the present invention is to provide a coloring agent mixer that can completely knead even particles that are difficult to mix in a solvent in a single charge and that can be used efficiently in a short period of time.

(Structure of the invention) The coloring material mixer of this invention has a screw shaft inserted into a heating cylinder having a coloring material input port at one end and a discharge port at the other end, and kneading materials are placed at appropriate locations on the screw shaft. A kneading tooth profile in the shape of a gear is formed on the outer periphery of the crest of the screw shaft at the kneading position by setting the position, and the heating cylinder at the kneading position has an axis parallel to the screw shaft, and the inner wall A cylindrical shaft-shaped storage chamber is provided in which a portion of the screw shaft overlaps with the screw shaft, and a kneading planetary shaft having a gear shape engraved on the circumferential surface that meshes with the kneading tooth profile of the screw shaft is stored in this storage chamber. It is characterized by

(Effect of the invention) According to the colorant mixer of this invention, the coloring materials such as dyes and pigments put into the heating cylinder are kneaded while being pressurized by the screw shaft, and furthermore, at the kneading position during the transfer, the coloring materials such as dyes and pigments are The kneading planetary shaft meshing with the kneading planetary shaft crushes the material and repeats the stretching and compression even more strongly. That is, the tooth profile of the planetary shaft faces into the spiral groove of the screw shaft, and by obtaining a kneading operation that crushes the raw material transferred in the spiral groove with this tooth profile, high kneading can be obtained. Therefore, even if the raw material is extremely viscous or is difficult to dissolve, the colorant extruded from the outlet will be thoroughly kneaded, and a sufficient effect can be expected with only one kneading action.

Therefore, there is no need to knead for a long time using a stirrer as in the past, and the working time is significantly shortened, resulting in increased efficiency.

(Example) An example of the present invention will be described below based on the drawings.

Fig. 1 shows a coloring material mixer according to this invention, which generally includes a cylindrical heating cylinder 1, a screw shaft 2 inserted into the heating cylinder 1, and a coloring material input port opened at the upper part of the starting end. 3, a second coloring raw material input port 4 opened at the middle part in the length direction,
A first hopper 5 attached to these input ports 3 and 4,
A second hopper 6, a deceleration mechanism section 7 of the screw shaft 2, a drive pulley 8 interlocked with a motor (not shown), a band heater 9 wrapped around the outer circumference of the heating cylinder 1, and a nozzle 10 provided at the discharge port. Become.

The outlet side of the screw shaft 2 from the second coloring material input port 4 is set as a kneading position 11, and a kneading tooth profile in the shape of a gear is formed on the outer periphery of the crest of the screw shaft 2' at this kneading position 11. ing.

The heating cylinder 1 at the kneading position 11 has a plurality of cylindrical storage chambers 12 at regular intervals, each having an axis parallel to the screw shaft 2 and having a part of the inner wall overlapped with the screw shaft 2. These storage rooms 12...
Inside, a kneading planetary shaft 13 is housed, which is carved with a gear shape that meshes with the tooth profile of the screw shaft.

In a coloring agent mixer having such a configuration, a coloring material that needs to be preheated is inputted from the first hopper 5, and is heated and pressurized in advance in the front half of the screw shaft 2 to knead it to an appropriate molten state. . From the second hopper 6, the coloring material that requires compression is directly introduced into the kneading position of the heating cylinder 1, where it is mixed with the coloring material in a pre-molten state.
While continuously crushing the raw material particles with the strong crushing and crushing stirring force generated by the meshing with the mesh, the raw material particles are further kneaded and stirred and sent to the discharge port side, and the colorant that has become completely melted and kneaded is passed through the nozzle. Discharge from 10.

In the above embodiment, two input ports were provided at the front and rear. However, depending on the type of mixed raw materials, the second coloring material input port 4 may not be used and may be used as a vent hole. The same kneading effect can be expected even when using only the following.

In this way, the colorant mixer of the present invention has a completely different configuration from conventional stirrers, and in particular, at the kneading position equipped with a planetary shaft, colorants of any nature can be sufficiently mixed, and moreover, it can be done efficiently in a short time. It has the advantage that it can be carried out.
