Document Type and Number:
WIPO Patent Application WO/2024/042778
Kind Code:
A1
Abstract:
This fibrous filler stirring/supplying device enables uniform and stable conveyance using a screw, even for fibrous fillers that spread readily, have low bulk density, and aggregate readily into cotton-like formations. The fibrous filler stirring/supplying device feeds fibrous filler from a hopper accommodating the fibrous filler to a discharge section, and is characterized by: comprising a connection tank between the hopper and the discharge section; being provided with, in the connection tank, a shaft that rotates about a rotation axis, and stirring blades for stirring the fibrous filler, the blades being attached at the tips of the shaft so as to rotate along the inner periphery of the connection tank; and the stirring blades being inclined inward at an angle Θ of 10° to 70° with respect to the rotational direction of the stirring blades.
