The present invention relates to a stirring apparatus for dissolving a solid adhesive, and more particularly, to an agitating apparatus for improving a dissolving speed of a solid adhesive by using an impeller having a converging plate and a cutting edge formed thereon.

As a method for producing a liquid adhesive having a moderate adhesiveness, there are known processes for preparing a plate- or block-shaped high adhesive adhesive and a liquid low adhesive adhesive by dissolving in a solvent to mix them. Such processes are typically performed by adding a solvent, a plate-like or bulky high-adhesive adhesive, and a low-adhesive adhesive necessary for the preparation into a stirring vessel, followed by stirring the impeller and producing a uniform liquid adhesive. A typical stirring device used in this case is shown in FIG.

Referring to FIG. 1, the stirring device 10 used in the related art for producing a liquid adhesive having moderate adhesiveness is a plate-like or bulk-shaped solid material having high elasticity and a low adhesiveness of a liquid. When the pressure sensitive adhesive and the solvent are accommodated in the stirring vessel 12, the motor 14 rotates on the shaft 18, and when the shaft 18 rotates, the impeller 16 attached to the shaft 18 rotates together. . The impeller 16 is usually formed with an impeller member 17 extending in a direction perpendicular to the shaft 18, the impeller members 17 having the same width outwardly from the shaft 18, as in FIGS. 2A and 2B. (l) and the shape of the same height h. As such, when the various substances contained in the stirring vessel 12 are mixed by the rotation of the impeller 16 located at different heights of the shaft 18, the adhesive, the adhesive, and the solvent are mutually chemically dissolved to dissolve the appropriate viscosity. A liquid adhesive with is produced.

In order to manufacture the liquid adhesive, a uniform phase in which the plate-like or bulk-adhesive high-adhesive adhesive is completely dissolved is required. In the case of the high-elastic, high-adhesive adhesive, the dissolution time is long, and thus serves as a bottleneck for the entire manufacturing process. There has been a problem.

Although methods for increasing the stirring speed have been proposed as a way to shorten the dissolution time, there has been a problem that the dissolution rate does not increase in proportion to the increase in the stirring speed due to the difference in the flow characteristics between the solid adhesive and the liquid solvent and the pressure-sensitive adhesive.

 In addition, the stirring apparatus 100 includes a first cutting blade 160 protruding outwardly from the converging plate 150, a second cutting blade 170 protruding downwardly from the impeller 140, and the stirring container 110. A plurality of locking projections 180 are further included to protrude inwardly from the shaft to pass through the first cutting blade 160.

The convergence plate 150 induces the flow so that the receiving material friction with the rotating impeller 140 flows downward while the flow of the receiving material is blocked in the center direction.

Of course, it is natural that the downward flow in the rotation radius of the impeller 140 is induced by the convergence plate 150, the upward flow outside the convergence plate 150.

Therefore, the receiving material inside the stirring vessel 110 is naturally formed a constant flow flow.

In addition, the convergence plate 150 is preferably installed at the end of the impeller 140, as shown in Figures 4a to 5b, of course, may be installed in the middle of the impeller 140.
