Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a Huber-type muller in which a heating element is incorporated inside a mixing board used for testing printing inks, paints, etc.

[Conventional technology]

Conventional hot-melt and thermoplastic resins and colorants,
For color toning tests and kneading tests of other additives, small three-roll, two-roll, extruders, kneaders, Banburys, etc. are widely used. When making samples using these machines, a preliminary time of 10 to 40 minutes is required to reach the set temperature, and after making one sample it always takes 1 to 4 hours, including disassembly of the main parts. Time is required for machine cleaning.

When testing using the above-mentioned machine in this way, as explained above, it takes a considerable amount of time to prepare one sample, which is a major drawback in terms of efficiency.

[Problems to be Solved by the Invention] The present invention incorporates a heating element inside a Huber-type Muller mixing board, which is widely used for testing printing inks and paints.
Concerns expanded to include testing of colorants, etc.

[Means for solving problems]

The present invention relates to a Huber-type mullet with a heat-generating mechanism. In a Huber-type mullet with a heat-generating mechanism, the heating part only needs to be a thin kneading plate, so its heat capacity is small and the preliminary time required to reach the set temperature is short. In addition, cleaning the machine after making one sample requires only a flat or two mixing plates, making it easy to clean the machine and making it possible to prepare samples in a short time.

Therefore, if the Huber-type Muller of the present invention is used, not only the uses of the Huber-type Muller can be expanded, but also the efficiency of sample preparation can be greatly improved.

Applications of this invention include testing of additives such as colorants, stabilizers, fillers, and ultraviolet absorbers, as well as kneading, dispersion, and coloring of heat-melting properties, plastics such as thermoplastic resins, varnishes, solvents, etc. It can be used to test printing inks, paints, coloring resins, mixing additives into resins, powder coatings, electrophotographic dry developers, synthetic fibers, etc.

In the present invention, the method of generating heat and the shape of the heating element may be of any type, as long as the heating mechanism is built into either one of the two upper and lower mixing plates, or the heating mechanism is built into the two upper and lower mixing plates. The drawings will be explained below. Glass plates are often used in the widely used Hoover-type Muller mixing plate, but in the case of the present invention, the material of the mixing plate is not specified, but a metal plate is suitable.

In Fig. 1, reference numeral 1 denotes a Hoover-type mullet main body, and the Hoover-type mullet main body 1 is provided with two mixing boards, an upper and lower mixing board 2 and a lower mixing board 3. A fine mixing plate 2 is placed thereon, and kneading, dispersion, etc. are performed by rotating the preliminary mixing plate 3. This kneading, dispersion, etc. action is due to the rotation of the motor 4, and the rotation speed of the motor 4 is adjusted by the rotation speed adjustment device 5. Further, the polishing plate 2 is provided with a pressure adjustment weight 6, and the pressure of the polishing plate 2 is adjusted. Note that 7 is a switch.

FIG. 2 shows a case in which a heating element is incorporated into the pre-drilling plate 3 of such a Huber-type muller 1, but the present invention is not limited to this, and the pre-drilling plate 3 and the pre-drilling plate 3 are incorporated in the finishing plate 2. Similarly, a device incorporating a heating element may also be used.

In FIG. 2, the preliminary board 3 is divided into an upper board 8 and a lower board 9, and the lower board 9 and the frame 10 are fastened and fixed. For example, the upper board 8 is fitted into the frame 10. After installing, carve a screw into the lower plate material 9,
It is only necessary to fasten it to the frame body 10.

A heating element 11 is provided between the upper plate material 8 and the lower plate material 9.
A thermocouple 12 is inserted through the lower plate 9 and extends near the surface of the upper plate 8 to adjust the temperature of the pre-drilling plate 3.

[Action and effect]

Therefore, the present invention is a pre-drilling board 3 and/or a finishing board 2 incorporating a heating element 11, in which a thermocouple 12 is attached to the surface of the upper board 8 so as to adjust the temperature of the heating element 11. Since it is located nearby, the temperature can be adjusted to the optimum temperature, so the Hoover-type Muller can be used for testing resins, additives, colorants, etc.

In addition, since the heat capacity of the Hoover type muller is small, the preliminary time required to reach the set temperature is short, and cleaning of the machine after sample preparation only requires cleaning the top and bottom two mixing plates, which can be done in a short period of time, increasing the efficiency of sample preparation. Greatly improved.
