Conventionally, when manufacturing foamed plastics such as hard urethane foam, in which two or more resin liquids are mixed and cured by reaction,
A mixing injection device as shown in FIG. 2 is used. In the figure, reference numeral 2 denotes an injection head, and within the injection head 2, a stirring blade 1 is rotatably disposed. The reactive resin liquid is placed on both sides of the upper part of the injection head 2.
Injection ports 6, 6 for injecting a resin liquid into the injection head 2 are respectively provided, and a nozzle portion 5 is provided at the lower end of the injection head 2 for discharging the mixed resin liquid mixed inside. Reference numeral 7 designates the upper surface plate of the injection head 2, and this upper surface plate 7 is provided with a shaft hole 9 through which the shaft 8 of the stirring blade 1 passes.
is installed. The reactive resin liquid injected into the injection head 2 from each resin liquid injection port 6, 6 is mixed by stirring by the stirring blade 1, and the mixture is formed between the stirring blade 1 and the inner wall surface of the injection head 2. Room 1
1 flows down and is discharged from the nozzle portion 5 of the injection head 2, and this mixed resin liquid is injected and filled into the back surface of a substrate such as a molded plate and hardened. However, the entire amount of the reactive resin liquid injected into the injection head 2 from each resin liquid injection port 6 does not flow down through the resin mixing chamber 11 of the injection head 2, but a portion of the resin liquid flows through the injection port. There is a problem that the mixture also enters the mixing chamber 11 above the mixing chamber 6 and remains there. When the reactive resin liquid stagnates in the upper part of the mixing chamber 11 of the injection head 2 in this way, the reactive resin liquid reacts and hardens in that area and adheres to the inner wall surface of the injection head 2, resulting in continued operation for a long time. The hardened material A was deposited as shown in the figure and became a resistance to the stirring blade 1, causing heat generation and seizure, making it impossible to operate. In addition, a portion of the resin liquid adheres to the surface of the shaft 8 and the oil seal 10, causing heat generation and burning, which may cause damage to the oil seal 10.

It is an object of the present invention to provide a mixing injection device that does not undergo reaction hardening, can be operated for a long time, and does not damage oil seals or the like.

防止することができるものである。 Thus, the reactive resin liquid is supplied to the injection head 2 from the upper resin liquid injection port 3 and the lower resin liquid injection port 4, respectively.
When injected into the mixing chamber 11, both resin liquids are mixed in the mixing chamber 11 by stirring by the stirring blade 1.
At the same time, each resin liquid flows down in the mixing chamber 11 due to its own weight and is discharged from the nozzle portion 5. At that time, each resin liquid may enter the mixing chamber 11 above the injection ports 3 and 4 due to the pressure at the time of injection and the rotational force of the stirring blade 1, but the upper resin liquid injection port 3 Since the lower resin liquid inlet 4 is provided with a level difference between the upper and lower sides as described above, only the resin liquid injected from the upper resin liquid inlet 3 enters the upper part of the mixing chamber 11 with priority. Then, only the resin liquid from the upper resin liquid injection port 3 is accumulated in the upper part of the mixing chamber 11, and the resin liquid injected from the lower resin liquid injection port 4 is mixed into the upper part of the mixing chamber 11. There is no such thing. Therefore, the mixing chamber 11
No reaction occurs in the upper part of the mixing chamber 11 and the oil seal 10 can be prevented from hardening and adhesion of the cured product, and even during long-term operation, heating and
It does not cause burn-in.
Therefore, this means that when the operation is stopped, the mixing chamber 1
1 has the advantage that the inside can be easily cleaned.
In other words, when cleaning, conventionally, after stopping the injection of both resin liquids, the cleaning solvent is injected into the mixing chamber 11 to clean the inner wall surface, and then air is blown in to volatilize the cleaning solvent. However, by injecting only the resin liquid injected from the upper resin liquid inlet 3 into the mixing chamber 11 and expelling the mixed resin liquid inside, the cured product can be kept on the inner wall surface even after the operation is stopped. Therefore, cleaning with a cleaning solvent can be performed extremely easily. In addition, the upper part of the stirring blade 1 and the upper surface plate 7 of the injection head 2
By interposing the O-ring 12 between
Closing the gap between the stirring blade 1 and the upper plate 7 prevents the resin liquid from flowing into the oil seal 10 side, further increasing the above effect, and also preventing the resin injected from the upper resin liquid injection port 3. Since only the liquid accumulates in the upper part of the mixing chamber 11, it is possible to prevent the mixed liquid from entering.

とができる。 In addition, as the reactive resin liquid used above, for example, in the production of rigid urethane foam, a polyol component and an isocyanate component can be used. Here, a component with a lighter specific gravity among both components, for example, a polyol component, is added to the upper resin liquid injection port 3.
It is preferable to inject into the injection head 2 from the inside. That is, the upper resin liquid injection port 3 and the lower resin liquid injection port 4
By creating a difference in the upper and lower levels of the mixing chamber 11, only the resin liquid from the upper resin liquid inlet 3 is preferentially filled into the upper part of the mixing chamber 11. By injecting the resin liquid from the upper resin liquid injection port 3, only this resin liquid is ensured to accumulate in the upper part of the mixing chamber 11 without being mixed. Moreover, if the polyol component of both components is injected into the mixing chamber 11 from the upper resin liquid injection port 3, no trouble will occur even when the operation is stopped. That is, the isocyanate component has the property of curing by reacting with moisture in the air, but the polyol component does not react with moisture in the air unless mixed with the isocyanate component, so the polyol component is placed in the upper part of the mixing chamber 11. This is because even if the line is stopped while it is injected and filled, it will not harden. In addition, this mixing injection device is not limited to the production of hard urethane foam, but can also be used to mix and react two or more types of reactive resin liquids, such as epoxy resins, phenolic resins, and urea resins. It can also be applied to mixing of alkyd resins, etc.

As described above, the present invention provides resin liquid injection ports into which the reactive resin liquid is injected on both sides of the upper part of the injection head in which stirring blades are disposed inside, and connects one resin liquid injection port to the other resin liquid injection port. Since it is formed above the liquid injection port, only the resin liquid injected into the injection head from the upper resin liquid injection port will preferentially enter and accumulate in the upper part of the mixing chamber. In this case, the reactive resin liquid does not mix and harden, allowing long-time operation, and there is no fear of damage to oil seals or the like. Furthermore, when manufacturing rigid urethane foam, if the polyol component is injected into the injection head from the upper resin liquid injection port, the interior of the mixing chamber will automatically fill with the polyol component when the line is stopped due to the above-mentioned effect. To be washed with
There is no need to clean the inside every time the line is stopped. In addition, the shaft of the stirring blade is passed through the shaft hole formed in the top plate of the injection head, and an O-ring is interposed between the stirring blade and the top plate of the injection head around the shaft. This prevents the resin liquid from flowing into the oil seal side by blocking the gap between the oil seal and the oil seal, thereby ensuring the effect of preventing a portion of the reaction liquid from entering the oil seal and hardening there, causing seizure. It has the advantage of being possible.
