[0002] Embroidery is a general term for various decorative patterns embroidered on fabrics by needles and threads. Embroidery is divided into silk thread embroidery and feather embroidery. It is to use a needle to pierce silk thread or other fibers and yarns on the embroidery material in a certain pattern and color, and use embroidery marks to form decorative fabrics with patterns. It is a technology that uses needles and threads to add human design and production to any existing fabric. In the process of embroidery, an embroidery frame is usually used. During the use of the embroidery frame, it is necessary to use a positioning device to fix it. The existing embroidery frame is fixed on the servo motor by plugging, and then the servo motor drives the movement of the embroidery frame. However, the existing fixing method is mostly unilateral fixing. During the movement, due to the excess fabric, the fabric may be clamped on the lower side of the embroidery frame, so that the embroidery frame moves unsmoothly. In addition, the unilateral fixing method may cause the embroidery frame to deform and make the clamping unstable during long-term use. For this reason, the utility model proposes an embroidery positioning device for an embroidery machine to solve the above problems. Utility Model Content

[0035] The principle and working process of the utility model

[0036] When in use, after fixing the fabric on the embroidery frame 4, the embroidery frame 4 is placed on the limiting frame 3.

At this time, the first spring 15 is compressed, and then the edge of the fabric is placed on the lower side of the pressing block 21 and clamped. At this time, the fabric is fixed. When moving, the servo motor 5 will drive the mounting block 6 to move left and right. After the rotating motor 17 is started, the gear 16 is driven to rotate by the forward and reverse rotation of the output shaft, thereby driving the limiting frame 3 to move forward and backward through the tooth meshing with the rack 7.
