阅读说明：本技术 无梭织机的纬纱切断装置 (Weft cutting device for shuttleless loom ) 是由 卢西亚诺·科瑞恩 于 2019-09-12 设计创作，主要内容包括：无梭织机的纬纱切断装置,其放置在一侧的织物边缘(1)、梳(2)和经口与另一侧的纬纱选择机构之间,来自多个孔眼(5、6、7、8、9、10、11、12)的纬纱在位于织物边缘(1)及织物形成所在的梳(2)的打纬线处的顶点(V)处结合。特别地,该装置由具有切割边缘的旋转盘(19)组成,旋转盘(19)通过使其保持旋转的马达(18)和通过设置有偏心轮(17’)的旋转轴(17)控制铰接杆(15)的动作的步进控制马达(25)来切断纬纱,杆(15)配置成相对于步进控制马达(25)的纵轴(26)摆动。杆(15)的一端以两个臂(13,14)的形式成形,这两个臂(13,14)分别搁置在两个弹性板(20,21)的表面上,并且,杆(15)的另一端还与偏心轮(17’)相连。(Weft cutting device for shuttleless looms, placed between the fabric edge (1) on one side, the comb (2) and the selection means of the weft on the other side and the transom, the weft coming from a plurality of eyelets (5, 6, 7, 8, 9, 10, 11, 12) being joined at the vertex (V) located at the fabric edge (1) and at the beat-up line of the comb (2) where the fabric is formed. In particular, the device consists of a rotating disc (19) with a cutting edge, the rotating disc (19) cutting the weft yarn by means of a motor (18) keeping it rotating and a step-control motor (25) controlling the action of an articulated lever (15) by means of a rotating shaft (17) provided with an eccentric (17'), the lever (15) being arranged to oscillate with respect to the longitudinal axis (26) of the step-control motor (25). One end of the rod (15) is shaped in the form of two arms (13,14), the two arms (13,14) resting on the surfaces of two elastic plates (20,21), respectively, and the other end of the rod (15) being also connected to an eccentric (17').)
