Description

Technical Field

[0001] The present application relates to the field of embroidery positioning, and in particular to a positioning device for embroidery machine embroidery. Background Art

[0002] Embroidery machine, also known as computer embroidery machine, is the most advanced embroidery machine in the contemporary era. It can realize traditional manual embroidery at high speed and high efficiency, and can also realize the requirements of "multi-level, multi-function, unity and perfection" that manual embroidery cannot achieve. It is a kind of electromechanical product that embodies a variety of high-tech. As computer embroidery replaces manual embroidery, computer embroidery machine will also become the main machine type in the embroidery industry. When the existing embroidery machine is used to flat embroider the fabric, the fabric needs to be supported and tightened by the flower frame. The existing embroidery machine flower frame is fixed on the equipment, mostly by using double-sided tape to stick the flower frame on the work station board of the equipment, and then put the fabric on the flower frame, and then fix the fabric on the flower frame with the flower frame ring. This method has poor positioning and fixing effect on the flower frame, which is easy to cause the flower frame to move during the embroidery process, resulting in embroidery failure. At the same time, the flower frame ring is used to squeeze and fix the embroidery cloth on the flower frame ring, which cannot ensure the firmness of the embroidery cloth.

[0003] The patent with application number 202321225292.X discloses a positioning device for embroidery machine embroidery, including a mounting column, the top of which is fixedly connected with an adjustment sleeve, the inner movable sleeve of the adjustment sleeve is connected with a slider No. 1, the top of the slider No. 1 is fixedly connected with a support sleeve, when the cloth needs to be fixed during cloth embroidery, the cloth is fixed on the sides of the two fixed columns, and the No. 2 threaded column is rotated at this time, so that the No. 2 threaded column drives the fixed column to move horizontally through the No. 2 slider, so that the fixed column can drive the fixed cloth to be tightened, thereby achieving the effect of adjusting the distance between the two fixed columns.

[0004] The above technical solution utilizes a spring clip to clamp and fix the embroidery fabric, and the spring clip tightens the embroidery fabric by rotating the threaded rod. However, since the spring clip is affected by the tension of the embroidery fabric, the spring thereon deforms and causes the embroidery fabric to loosen. In addition, since the threaded rod lacks axial positioning, the slider is affected by the tension of the embroidery fabric and slides on the threaded rod, thereby affecting the tension and fixation of the embroidery fabric and resulting in poor stability in the positioning of the embroidery fabric.
