摘要： The present invention relates to an under-thread supply device for a sewing machine, and more particularly, to an enhanced under-thread supply device for a sewing machine, in which the device of the present invention and a unit for mounting said device are just partially changed so as to increase the winding amount of the under-thread of conventional sewing machines in order to achieve improved efficiency of sewing and efficiently reduce the puckering of a work piece without causing changes in the basic structure of conventional sewing machines. The under-thread supply device (A) for a sewing machine according to the present invention, comprises, as shown in the attached Fig. 1 : a hook unit (1) having a body hook (200) arranged rotatably therein so as to extract an under-thread (11), pass the under-thread (11) directly through the upper thread ring (12') and interconnect the under-thread (11) and the upper thread (12) so as to thereby stitch (stitch) the work piece; and an under-thread unit (2) which has a U-bobbin (400) arranged therein, and which is inserted and connected to an under-thread accommodation unit (207) of the body hook (200), wherein the U-bobbin (400) with a roll of under-thread (11') is accommodated in a U-bobbin case (500) so as to supply the under-thread (11) for stitching (stitching) the work piece. The hook unit (1) comprises: a driving unit (100) for receiving power from a power transmission shaft (not shown) of conventional sewing machines and rotating a rotary shaft (130) by driving a gear using the received power so as to rotate a power ring (150) coupled to the rotary shaft (130) through a link (140); the body hook (200) which rotates by the rotating power transmitted from the power ring (150) of the driving unit (100), and which accommodates the under-thread unit (2) therein and interconnects the under-thread (11) and the upper thread (12) directly through the upper thread ring (12'); and a coupling member (300) for coupling the driving unit (100) and the body hook (200). Further, the under-thread unit (2) comprises: the U-bobbin (400) having the roll of under-thread (11') therein, wherein the U-bobbin (400) is arranged in the U-bobbin case (500); and the U-bobbin case (500) for accommodating therein the U-bobbin (400) having the roll of under-thread (11') therein, and the U-bobbin case (500) is inserted and connected to the under-thread accommodation unit (207) of the body hook (200). According to the present invention, provided is a new concept enhanced under-thread supply device for a sewing machine, in which the device of the present invention and a unit for mounting said device are just partially changed to increase the winding amount of the under-thread of conventional sewing machines so as to achieve improved efficiency of sewing and efficiently reduce puckering of a work piece without causing changes in the basic structure of conventional sewing machines.
摘要翻译： 缝纫机的底线供给装置本发明涉及缝纫机的底线供给装置，更具体地说，涉及缝纫机的增强底线供给装置，其中本发明的装置和用于安装所述装置的单元正好 部分地改变以增加传统缝纫机的底线的卷绕量，以便实现提高的缝纫效率并有效地减少工件的褶皱而不会改变传统缝纫机的基本结构。 如附图1所示，根据本发明的用于缝纫机的底线供应装置（A）包括：钩单元（1），其具有可旋转地布置在其中的主体钩（200）以提取 （11），使底线（11）直接穿过上线环（12'）并将底线（11）和面线（12）互连以便由此缝合（缝合） 工件; 和设置在其中的U形线轴（400）并且插入并连接到主体钩（200）的底线容纳单元（207）的底线单元（2），其中U形线轴 带有一卷底线（11'）的织物（400）容纳在U形梭壳（500）中，以提供用于缝合（缝合）工件的底线（11）。 钩单元（1）包括：驱动单元（100），用于从传统缝纫机的动力传递轴（未示出）接收动力并且通过使用接收的动力驱动齿轮来旋转旋转轴（130）以旋转 通过连杆（140）联接到所述旋转轴（130）的动力环（150）; （100）的动力环（150）传递的旋转动力而旋转的主体钩（200），该主体钩（200）将底线装置（2）收纳在内部，将底线（11）与 上线（12）直接穿过上线环（12'）; 和用于联接驱动单元（100）和主体钩（200）的联接构件（300）。 此外，底线单元2包括：其中具有底线（11'）卷的U形线轴（400），其中U形线轴（400）布置在U形线轴壳体（500）中 ）; 和用于在其中容纳其中具有一卷底线（11'）的U形梭（400）的U形梭壳（500），并且U形梭壳（500）插入并连接到底线 主体钩（200）的容纳单元（207）。 根据本发明，提供了一种用于缝纫机的新概念增强型底线供应装置，其中本发明的装置和用于安装所述装置的单元被部分地改变以增加底下部件的缠绕量， 以提高缝纫效率，并有效地减少工件的起皱，而不会改变传统缝纫机的基本结构。
