る。b. Conventional techniques and their problems Conventionally, two liquids, for example two liquids consisting of a base material and a curing agent, which harden when mixed together, have been used to bond glass fiber reinforced plastics (FRP) together or FRP and metal. A two-liquid mixing and discharging device that mixes and discharges liquid adhesives is used.
この種の装置では、主剤と硬化剤の二液を撹拌

ちに供給して、接着作業に供する。 In this type of device, two liquids, the base resin and the curing agent, are fed into a stirring and mixing chamber, and after mixing these liquids in the stirring and mixing chamber, they are quickly supplied to the area to be used from a nozzle to form the adhesive. Use for work.

になつたりしていた。 At this time, most of the two liquids mixed in the stirring mixing chamber are sequentially discharged from the nozzle, but some of them are near the bearing part of the support drive shaft of the stirring rod disposed inside the stirring mixing chamber. There was a risk that it would accumulate and solidify. In such cases, the rotation of the stirring rod may be hindered, or it may become difficult to disassemble and clean the two-liquid mixing and discharging device.

必要があつたが、このような分解清掃等の保守作
業は容易でなかつた。 To explain in more detail, in the above-mentioned two-component mixing device, at the point where the supply passages for the main agent and the curing agent intersect, when the main agent and the curing agent collide and merge, they may form a turbulent flow and stagnate. . Due to this stagnation phenomenon, the mixing ratio of the base resin and the curing agent may deviate from the normal ratio, and the base resin may react with the curing agent and harden, producing lumps. The resulting lumps often remain and accumulate within the apparatus, particularly in the supply passage or the stirring and mixing chamber, often rendering the apparatus unable to operate. For this reason, it was necessary to frequently disassemble and clean the apparatus itself in order to remove lumps that were stuck inside the apparatus, but such maintenance work such as disassembly and cleaning was not easy.

直接供給するための通路である。 The main body 10 is formed with a passage 15 for a main agent (hereinafter referred to as liquid A) and a passage 16 for a curing agent (hereinafter referred to as liquid B). Here, the passage 15 is communicated with one end of the stirring and mixing chamber 1 through an axial supply passage 15a formed in the main body 10 at a distance from the cavity 20. In addition, the passage 16 passes through the hollow part 20 around the support drive shaft 6 into the stirring and mixing chamber 1.
is connected to one end of the The proximal end of each passage 15, 16 is connected to a supply source (not shown) of the main agent and curing agent via valves 17, 18, respectively. Reference numeral 19 represents a handle for opening and closing the valves 17 and 18 at the same time, and reference numeral 21 represents a passage for directly supplying cleaning solvent to the cavity 20.

を洗い流す。 Now, the air motor 14 is driven to rotate the stirring rod 4 via the support drive shaft 6. Then, when the handle 19 is operated to open the valves 17 and 18,
The base agent and the curing agent enter the stirring and mixing chamber 1 through the passages 15 and 16, are mixed by the row of protrusions 5, and are discharged from the nozzle 2. At this time, the entire amount of the curing agent flowing through the passage 16 enters the cavity 20 and flows into the stirring and mixing chamber 1 from its front end. When the work is finished, close the valves 17 and 18 to stop the supply of the two liquids, and then immediately close the solvent supply valve (not shown).
By opening the passage 21, a solvent (for example, methylene chloride, acetone, etc.) is supplied from the passage 21 toward the empty space 20, and the solvent is introduced into the stirring and mixing chamber 1 from the empty space.
The two-component mixture remaining in the empty space 20 and the stirring and mixing chamber is washed away.

掃を効率よく行える。 According to the apparatus of the above embodiment, the curing agent is in the empty part 20.
Since the two liquids flow into the stirring and mixing chamber 1 in a filled state, the two liquids are prevented from stagnation and solidification near the bearing portion of the support drive shaft 6 and the tip of the bearing portion. Furthermore, since the device can be disassembled all at once by screwing in and removing the cap nut 3, necessary parts can be cleaned efficiently.

A cylindrical cavity communicating with the mixing chamber is provided, one of the supply passages is directly communicated with the stirring and mixing chamber,
Since the other side is connected to the stirring and mixing chamber through the hollow part, the vicinity of the connecting part between the end of the drive shaft and the stirring rod is connected to the two liquids through the hollow part. It can be kept filled with one of the supplied liquids at all times, and therefore, when the device is in use, the two liquids mix and solidify at the connection site, thereby preventing rotation of the stirring rod. This can be effectively prevented.
