Description

Technical Field

[0001] The utility model specifically relates to an adjustable thread take-up tension structure, belonging to the technical field of embroidery. Background Art

[0002] The thread take-up tension structure is a crucial part in an embroidery machine, which directly affects the quality and stability of embroidery. Its main function is to supply and recycle an appropriate amount of top thread through a specific movement mode during the embroidery process, and to tighten the knot formed by the intersection of the top thread and the bottom thread in the center of the sewing material, ensuring that each embroidery thread is subjected to uniform tension during the embroidery process, thereby improving the overall quality and consistency of the embroidered product.

[0003] The existing thread take-up tension structures are usually set in multiple groups to ensure that each embroidery thread is subjected to uniform and stable tension during the embroidery process. When adjusting the tension of different groups of thread take-up tension structures, it is necessary to remove the thread take-up tension structure for individual adjustment, which is inconvenient to use and affects the efficiency of embroidery production. In addition, the existing tension structure usually uses steel wires for guiding during the thread take-up process, and the friction between the embroidery thread and the steel wire is likely to cause damage to the steel wire, affecting the thread take-up effect, and there are certain drawbacks in the use process.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

One end of the thread take-up spring holder is provided with the teeth, and the thread take-up spring holder is engaged with the limit chuck fixedly installed on the front cover through the teeth.

[0008] Further, in order to tighten the thread take-up coil spring by controlling the rotation of the thread take-up spring holder, the thread take-up coil spring is sleeved on the thread take-up spring holder. One end of the thread take-up coil spring is inserted into the limit card slot opened on the thread take-up spring holder, and the other end of the thread take-up coil spring corresponds to the thread passing slot hole opened on the front cover.

[0009] Further, in order to guide the embroidery thread passing in and out of the thread take-up coil spring through the guiding porcelain sleeve, the thread take-up coil spring is used to hook the embroidery thread, and the embroidery thread passes through the thread take-up coil spring and is respectively in close contact with the guiding porcelain sleeves on both sides.

[0010] Further, in order to rotate the thread take-up spring holder by controlling the rotation of the hexagonal adjustment shaft, a hexagonal through hole is opened on the thread take-up spring holder, and the hexagonal adjustment shaft is inserted into the hexagonal through hole. Both ends of the hexagonal adjustment shaft are rotatably inserted into the side cover.

[0011] Further, in order to rotate the hexagonal adjustment shaft through the circular rotating head, a circular rotating head is fixedly installed at one end of the hexagonal adjustment shaft. A plum blossom card slot is opened on the circular rotating head, and the circular rotating head is rotatably inserted into the side cover.

[0012] Further, in order to fixedly install the front cover on the main cover, the upper connection chuck and the lower connection chuck are fixedly installed at both ends of the inner wall of the front cover. The upper connection chuck and the lower connection chuck are clamped in the upper connection card slot and the lower connection slot opened on the main cover.

[0013] Further, in order to improve the stability of the front cover during use through the positioning chuck, the positioning chuck is also installed on the inner wall of the front cover. The positioning chuck is clamped in the middle connection card slot opened on the main cover.

[0014] The technical effects and advantages of the present utility model: Through the series-type thread take-up tension adjustment assembly, the tension of the embroidery thread wound around multiple front covers can be adjusted simultaneously without disassembly for separate adjustment, effectively improving the convenience of use and having higher production efficiency;

[0015] By rotating the guiding porcelain sleeve on the guiding shaft, the embroidery thread during the wire routing process can be guided, reducing the friction damping of the wire routing, solving the problem that the traditional wire guiding using steel wires is prone to wear, and having stronger practicability.
