Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an apparatus for uniformly stirring a viscous adhesive.

[Background technology]

Conventionally, the adhesive in the mixing bucket was mixed only with the propeller, but the mixing was insufficient because the adhesive could not reach the inner peripheral surface of the mixing bucket with the propeller alone. As a result, the adhesive near the inner peripheral surface could not be used and was wasted, and there was also the problem that cleanup took time.

[Purpose of invention]

The present invention was devised in view of the drawbacks of the conventional examples described above, and its purpose is to uniformly stir the adhesive near the inner circumferential wall surface of the stirring bucket.

[Disclosure of invention]

The adhesive stirring device of the present invention is provided with a stirring rod 2 that moves along the inner peripheral wall surface of a cylindrical stirring bucket 1,
The stirring rod 2 is provided with a large number of air blowing holes 3, and the above object can be achieved by moving (rotating) the stirring rod while blowing out air from the air blowing holes.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a cylindrical stirring bucket, into which adhesive A is placed. 2 is a cylindrical stirring rod with a bottom, and a large number of air blowing holes 3 are perforated on the circumferential surface, and when aero is fed from the upper end, air bubbles are blown out from the air blowing holes 3. ing. In the illustrated example, three stirring rods 2 are delivered so as to rotate along the inner peripheral wall surface of the stirring bucket 1, and the three stirring rods 2 are integrated by a hollow connecting bar 4. While rotating together around point A (coinciding with the center of the stirring bucket), the air fed from the air pipe 5 is blown out.
A flow as shown by the arrow in the figure is generated, and the aero hits the inner circumferential wall surface, so that the adhesive A is stirred sufficiently and evenly near the inner circumferential wall surface.

The main example of the above stirring rod is one in which the stirring rod is automatically moved (rotated) by the reaction force of the air blown out from the blow-off hole, but there are other ways to rotate the stirring rod using external power such as a motor. It is also possible to do so. In other words, in order to move the stirring rod using the reaction force of the blown air, it is necessary to provide the air outlet on the side opposite to the direction of movement of the stirring rod (or to set the air outlet on the opposite side of the direction of movement of the stirring rod). The stirring rod can be moved automatically by the reaction force of the air blown out from the blow-off hole, and at the same time, the air blown around the stirring rod can also stir the inner peripheral wall of the stirring bucket. It is done effectively.

In addition, when the stirring rod is rotated by external power such as a motor, it is possible to provide air blow-off holes evenly around the circumferential surface of the stirring rod. In terms of the stirring effect, air has the same effect as increasing the diameter of the stirring rod, and the air can stir up to the inner peripheral wall of the stirring bucket, and it is similar to the case when the diameter of the stirring rod is increased. There is also no problem of collision with the stirring bucket.

The number of stirring rods 2 can be changed as appropriate depending on the size and depth of the stirring bucket 1, the viscosity of the adhesive, etc. Further, although this stirring rod 2 can be used alone, it is also possible to combine it with a propeller.

[Effects of the invention] Since the present invention is constructed as described above, the adhesive can be stirred by moving the stirring rod, and the air blown from the air outlet hits the inner peripheral wall surface and reaches near the inner peripheral wall surface. The adhesive is stirred thoroughly and evenly.
This has the advantage that the adhesive does not adhere to the inner peripheral wall surface of the stirring bucket, eliminating waste, and making cleaning afterward easier.
