As shown in FIG. 2, the stirring rotor 8 is integrally provided with a drive shaft 9 projecting from one end thereof, and this drive shaft 9 passes through the bearing cover 3 and is led out to one end side of the cylinder 1. This drive shaft 9 is rotated by a motor (not shown), and therefore the stirring rotor 8 is also rotated integrally within the cylinder 1. An O-ring 10.11 is attached to the bearing cover 3 by means of a spacer 12 and a nut 13. The O-rings 10 and 11 are spaced apart from each other in the axial direction, and a spacer 1 is provided between them.

溝１８・・・により相互に導通している。The stirring rotor 8 is formed at one end with an end wall 14 that slides into contact with the end surface of the bearing lid 3, and a partition wall 15 is formed spaced apart from the end wall 14 in the axial direction. A liquid guide chamber 16 is formed in a space surrounded by the end wall 14, the partition wall 15, and the inner wall of the cylinder 1.
A stirring chamber 17 is formed in a space surrounded by the discharge lid 5 and the inner wall of the cylinder 1. The liquid introduction chamber 16 and the stirring chamber 17 are electrically connected to each other through a passage formed in the above-mentioned gap W15, for example, the notched groove 18.

開口している。A pair of injection pipes 19 and 20 are connected to the cylinder 1 . These injection pipes 19 and 20 are arranged to be displaced from each other in the axial direction of the cylinder 1, and one injection pipe 19 is connected to the liquid guiding chamber 16.
The other injection pipe 2o is open to the stirring chamber 11.

A measured amount of resin base material is supplied from one injection pipe 19, and a measured amount of curing agent is injected from the other injection pipe 2o. The resin base material injected from one injection pipe 19) enters the liquid guide chamber 16, fills this liquid guide chamber 16, and fills the notch groove 1.
8... flows into the stirring chamber 17.

をもつ末流を生じさせるので二液の混合が促進される。The curing agent supplied from the other injection pipe 20 enters the stirring chamber 17 directly. In the stirring chamber 11, the resin base material and the curing agent are stirred and mixed by the rotation of the stirring roller 8. In this case, since the stirring rotor 8 has a width across flats 21.22 and a spiral groove 23 formed on the circumferential surface perpendicular to these widths across flats 21.22, the width across flats 21.22 allows the inside of the stirring chamber 17 to be Mixing of the two liquids is promoted because a vortex is generated and a tail flow is twisted in one direction by the spiral groove 23.

る。The liquid mixed in the stirring chamber 17 in this way is transferred to the injection pipe 19
．． Since an axial flow is generated by the pressure of the main agent and curing agent that are pumped from 20, the mixed liquid flows through the drain port 6.
Therefore, it is ejected from the nozzle 7.

恐れはない。In such an embodiment, the stirring chamber 17 and the bearing lid 3 are separated by the partition wall 15, the liquid guide chamber 16, and the end wall 14, so that the mixed liquid in the stirring chamber 17 reaches the bearing lid 3. That will no longer be the case. To explain further, since the partition wall 15 and the end wall 14 are in sliding contact with the inner wall surface of the cylinder 1, these sliding surfaces not only prevent leakage of the mixed liquid, but also prevent the liquid mixture from leaking due to the resin main agent filled in the liquid guide chamber 16. To prevent the mixed liquid from flowing to the bearing lid 3 side. Only one ferment is injected into the liquid guide v1B, so there is no fear that the liquid will harden in the liquid guide chamber 1G.

な回転が可能になる。Therefore, according to this device, since the mixed liquid does not enter between the drive shaft 9 and the bearing cover 3, the frictional resistance between the drive shaft 9, the stirring rotor 8, and the bearing cover 3 due to hardening of the mixed liquid increases. This eliminates problems such as the drive shaft 9 and stirring rotor 8 becoming unable to rotate, and enables smooth rotation over a long period of time.

For example, one liquid filled in the liquid introduction chamber 16 causes the stirring chamber 17 to
The end wall 14 is omitted to prevent the mixed liquid from going around to the drive shaft 9 side, and the bearing cover 3 and the partition wall 15 form the liquid guiding chamber 1.
6 may be configured. Further, the passage formed in the partition wall 15 may be a through hole instead of the cutout groove 18. Furthermore, the partition wall 15 is not limited to being formed on the stirring rotor 8, but may be formed on the cylinder 1. Alternatively, the curing agent may be supplied from one injection pipe 19 and the main agent may be supplied from the other injection pipe 20.

持する。As described above, according to the present invention, one liquid in the liquid guide chamber partitioned by the partition wall seals the mixed liquid in the stirring chamber, so that the mixed liquid is prevented from entering the drive shaft side, and therefore the mixed liquid is driven. There is no hardening caused by the rotation of the shaft or stirring rotor, and the disadvantages of increasing frictional resistance on the drive shaft or making it impossible to rotate are eliminated, and smooth rotation is maintained over a long period of time.
