Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for mixing and agitating adhesives, paints, and other flow agents that are used in combination.

Some adhesives, paints, etc. are two-part or three-part mixable, and conventionally, when using them, each agent was poured into a suitable container and a stirring rod (specifically used) was used. A mixture was obtained by stirring the mixture. However, there is no special mixing container, and this method dirtyes hands and is inconvenient to handle. It is also difficult to obtain an accurate mixture, and it is difficult to apply the adhesive after mixing. It is also extremely inconvenient.

Therefore, the present invention provides an adhesive that can easily and reliably stir and mix two-component adhesives, etc., and that can be used for application etc. immediately after mixing without transferring to another container. The object of the present invention is to provide a mixing and stirring method and apparatus.

The method according to the present invention is characterized by injecting the liquid to be mixed and stirred into a bellows-type cartridge having at least one deep constriction in the center, and after sealing the container, alternately compressing the bellows-type stirring cartridge in half. The apparatus according to the present invention includes a bellows-type stirring cartridge having at least one deep constriction in the center and a protruding injection port covered with a removable cap; a cylinder into which the stirring cartridge is loaded with its neck being lockable; a stirring piston that slides inside the cylinder with its front end engaged with the constriction of the stirring cartridge; A mixing and stirring device for adhesives, etc., comprising an extrusion piston that moves back and forth in a cylinder separately from the stirring piston while the cap is locked, and the device is for carrying out the method described above. The drawings show examples of the implementation, and in the drawings 1
is a cylinder, and the one shown is a cylinder divided vertically. A collar 2 is formed on one end surface of the cylinder 1, and a protrusion 3 is provided on the other end surface. A groove 4 is formed on the inner surface of the protrusion 3. 5
is a piston receiver provided in the center of the collar 2, into which the extrusion piston 6 is fitted and slides. A locking hole 7 for locking a cartridge is formed at the tip of the extrusion piston 6. 8 A side plate 10 of a stirring piston 9 is housed in the slide grooves provided on both sides of the piston receiver 5 and slid therein. The stirring piston 9 is formed by sandwiching opposite side plates 10 between a donut-shaped end plate 11 and a hook plate 12 provided with a U-shaped groove.
Reference numeral 13 denotes a bellows-type stirring cartridge, which is usually provided with a constricted portion 14 at one location in the center. A plurality of constricted portions 14 are provided as necessary. A removable cap 15 is attached to the opening of the stirring cartridge 13. The cap 15 is provided with a fitting part 17 that fits tightly into the injection port (threaded part) 16 of the stirring cartridge 13 (see FIG. 2).

To explain an embodiment illustrating the operation of the present invention, first, the stirring cartridge 13 is set up, the cap 15 is removed, and about half of the plurality of chemical solutions to be mixed are poured into the cartridge. Then, fit the cap 15 again and connect the constriction 14 to the hook plate 1 of the stirring piston 9.
2 into the U-shaped groove, and the cap 15 is engaged with the front end locking hole 7 of the extrusion piston 6 inserted through the end plate 11. In this state, the protrusion 8 of the stirring cartridge 13 is fitted into the groove 4, and the stirring cartridge 13 is loaded into the cylinder 1. Thus, the state shown in FIG. 2 is reached. When the stirring piston 9 is pressed, the front half of the stirring cartridge 13 is crushed (the fourth
(Fig.), the chemical liquid present there is forced to the rear half. At this time, no force is applied to the extrusion piston 6. Subsequently, when the stirring piston 9 is pulled back and the extrusion piston 6 is advanced with respect to the stirring piston 9, the chemical solution that was in the latter half moves to the front half. While repeating such an operation, the plurality of chemical liquids are sufficiently stirred and mixed together with the current changing effect due to the unevenness of the bellows structure. Thereafter, by cutting off the tip of the stirring cartridge 13 and moving the extrusion piston 6 forward with respect to the cylinder 1, the mixture in the stirring cartridge 13 is gradually extruded. In addition,
When the cap 15 is provided with the fitting part 17, no mixture remains in the injection port 16 during extrusion, and the injection port 16 can be reinforced.

The present invention is as described above, and according to the method, it is possible to easily and reliably mix and dispense the contents regardless of the amount of contents, and since the stirring and mixing cartridge is sealed and sealed, bubbles are hardly generated. , it has the effect of saving labor such as defoaming, and in addition to the above-mentioned effects, in the invention of the device, it has a simple structure and is easy to operate, and because it is a cartridge type, the cartridge can be replaced even if the contents are of different types. It has the effect that it can be used repeatedly without washing or cleaning the container.
