- 粉体容器に形成された、回転軸が内外を貫通する軸穴と、
この軸穴の外側において回転軸を囲う箱体と、
この箱体に取付けられた、回転軸を支持する軸受体と、
軸穴を通る部分の回転軸の外周に形成された、軸穴と回転軸の隙間から箱体側に漏れる粉体を回転軸の回転によって粉体容器の内側に押し戻す螺旋状突起と、
この螺旋状突起と軸穴の間を通して箱体内に漏れた粉体の、開閉可能な蓋を取付けて箱体に備えた取出口と、を備えている、
ことを特徴とする粉体装置の軸受構造。 - 軸穴と回転軸の螺旋状突起の間を通し漏れた粉体の、箱体内への漏れ隙間を調整自在に規制する回転軸の外周部に取付けられた隙間規制部材を備え、
軸穴が、粉体容器の外側に向けて徐々に拡大するテーパ穴を備え、
隙間規制部材が、粉体容器に回転軸の軸線方向に移動可能に取付けられ粉体容器の内側に向けて徐々に縮小するテーパ軸を有したテーパ部材を備え、
このテーパ穴とテーパ軸の間に上記の漏れ隙間が形成され、
テーパ穴に対してテーパ軸を軸線方向に調整自在に移動させ漏れ隙間を、微粉体から粉粒体まで、粉体の粒径に合わせて調整することができる移動手段を備えている、
ことを特徴とする請求項1記載の粉体装置の軸受構造。 - 粉体装置が、
回転軸の回転によって投入口の粉体を排出口に送り出すものであり、
排出口に箱体内の粉体を導く排出路を備えている、
ことを特徴とする請求項1または2記載の粉体装置の軸受構造。
