Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a plate wire winding device with a protective function. Background Art

[0002] When a sewing machine is sewing fabrics, the shuttle and the needle cooperate with each other to interweave the bottom thread and the top thread and sew them on the fabric, thus forming a stitch. The bottom thread is generally short, so the bobbin needs to be replaced frequently during the sewing process and the empty bobbin needs to be wound. As a result, many sewing machine winding devices have emerged.

[0003] According to a disclosed sewing machine winding device (publication number: CN 220812892 U), in the above application, a wire control mechanism is arranged on the edge of the winding member, and the wire control mechanism can have a certain tensioning effect on the wound wire, so that the wire is wound more tightly, avoiding the wire jamming during the winding process; a rod body is arranged to be connected with the wire guide, and a transmission member is arranged inside the rod body, and the transmission member is connected with the micro-drive motor and the wire guide. The micro-drive motor can drive the transmission member to drive the wire guide, so that the wire guide can control the winding range, so that the wire is more evenly wound on the winding member, and the wire guide is connected to the rod body, and the rod body can control the winding range to avoid the wire being wound around the outside of the winding member.

[0004] However, in actual use of the above-mentioned device, the part of the conductor that touches the wire is set to a square shape. When the wire passes through the inside of the conductor, the square edge may damage the wire, causing the wire to break, affecting the integrity of the winding. In view of this, we propose a board winding device with a protective function. Utility Model Content
