Abstract

PURPOSE:To prevent the clogging of a route by a reaction product, by providing a communication hole to the central part of one of two kinds of mixing plates arranged to a main body passage and equalizing the route lengths up to a plurality of communication holes provided to the other mixing plate. CONSTITUTION:When a main agent is supplied to a confluent part from a passage 8a and a curing agent is supplied to the confluent part from a passage 8b, the main agent and the curing agent flow in the part at the central point A of a H-shaped route 11 of a second mixing plate 5 from the communication hole 10 to a first mixing plate 4 under mixing. Both agents are equally divided from said inflow part to flow to flow holes 13 under mixing through said route 11. The mixing stream flowing to the flow holes 13 is again gathered to the communication hole 10 of the next first mixing plate 4 under mixing and successively passes through the second mixing plate 5 and the first mixing plate 4 under mixing to be discharged to a predetermined area from a discharging port 6.

That is.

[Effect]

In such a two-component mixing and discharging device, when mixing and discharging a base agent and a curing agent, the base agent is supplied to the confluence section from one passage, and the curing agent is supplied to the confluence section from the other passage. As a result, the image side is sufficiently mixed by passing alternately through a mixing plate with a circulation hole formed in the center and a mixing plate with equal path lengths to the plurality of circulation holes. is discharged from the discharge port to a predetermined area.

When the mixed liquid consisting of the base agent and curing agent passes through the two mixing plates, the path lengths from the mixing plate with a distribution hole formed in the center to the distribution holes formed in the center are made equal. Since the mixing plates are arranged alternately, the mixed liquid always flows evenly and does not stagnate in the path it passes through. Therefore, there is no generation of reactants in the path through which the mixed liquid passes, and blockage is prevented.
