PROBLEM TO BE SOLVED: To solve problems in which the durability of a contact portion of a cutting edge decreases when a receiving roller of an elastic material is added in a strike-through state in order to absorb blurring in the rotational orbit of the cutting edge of a round knife assembled in a cutting blade roller, and dough dregs are deposited in a noodle string scraper and formed in an icicle-shape.SOLUTION: A cutting blade device is provided in which a cutting blade roller is formed by alternately assembling a round knife and a spacer, multiple annular grooves of vertical planes and slopes are formed in a rotary shaft in an outer circumference of a receiving roller, and the cutting blade roller is provided along with the receiving roller so that the cutting edge of the round knife may come close to the vertical plane of the annular groove of the receiving roller. The cutting blade device is configured such that the vertical plane of the cutting edge faces the vertical plane of the annular groove of the receiving roller in a single-edged blade where the round knife forms the cutting edge by the vertical plane and the slope. The cutting blade device is also configured such that a scraper becomes independent every groove part, is freely movable in the rotating axis direction of the cutting blade roller and comes in slide contact with the inner walls of both sides of the groove part, and the surface for receiving a noodle string forms a face angle in the position intersecting with the outer edge of the round knife.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】切刃ローラに組み付けた丸ナイフの刃先の回転軌道のブレを吸収する為、弾性素材の受けローラを食い込み状態に併設すると刃先の接触部分の耐久性が低下する。又、麺線スクレーパには生地カスが堆積してツララ状に形成する。【解決手段】丸ナイフとスペーサを交互に組みつけることで切刃ローラを形成し、受けローラの外周には回転軸に垂直面と斜面による環状溝を複数形成し、丸ナイフの刃先と受けローラの環状溝の垂直面が近接するように、切刃ローラと受けローラを併設する切刃装置や、丸ナイフが垂直面と斜面により刃先を形成する片刃で、刃先の垂直面と受けローラの環状溝の垂直面が対向する前記切刃装置。又、スクレーパが、溝部毎に独立し、前記切刃ローラの回転軸方向に移動自在で、溝部の両側内壁と摺接し、麺線を受ける面が丸ナイフの外縁と交差する位置に面角を形成する前記切刃装置。【選択図】図１
