Description

Technical Field

[0001] The utility model relates to the field of sewing machines, in particular to a material rack for sewing machines. Background Art

[0002] A sewing machine is a tool for making clothes, including many types. For example, a lockstitch sewing machine uses an upper thread and a lower thread to form a seam on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. The use of a sewing machine requires the material to be transported through a material rack.

[0003] The Chinese patent with the publication number CN216427602U discloses a sewing machine thread rack, which includes a support rod, a thread support rack and a lead frame. The thread support rack is provided with a tower wire tray, the lead frame is provided with a wire hole, the thread support rack and the lead frame are respectively detachably mounted on the support rod, and the bottom end of the support rod is provided with a threaded column, which is detachably connected to a nut. The technical effect achieved is: the thread support rack is provided with a tower wire tray, the lead frame is provided with a wire hole, the thread support rack is used in combination with the lead frame, the tower wire can be placed, and a guiding function is provided to ensure the normal use of the tower wire; the thread support rack and the lead frame are respectively detachably mounted on the support rod, and assembly and disassembly are convenient and quick; the bottom end of the support rod is provided with a threaded column, which is detachably connected to a nut, and the threaded column and the nut are used together to conveniently install and fix the support rod, thereby fixing the entire thread rack, and the overall structure is simple, easy to disassemble and assemble, and convenient to use.

[0004] During use, the above-mentioned equipment can conveniently disassemble and assemble the entire thread rack to improve its utilization efficiency. The tower wire is directly placed in a sleeve.

When the effect of centrifugal force becomes more obvious, it is easy for the tower wire to detach from the thread rack, thereby affecting the processing of the sewing machine. This needs to be optimized and improved. Utility Model Content
