DETAILED DESCRIPTION

The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

As shown in Fig. 1-3, a cloth clamping device for an embroidery machine includes a base 1, a pressing block 2 and a cover plate 3;

The base is provided with a groove 4, and the pressing block is provided with a protrusion 5 protruding from the groove and matching the groove. A plurality of lower magnets 6 arranged at intervals are fixed on both sides of the base, and upper magnets 7 are fixed on both sides of the pressing block facing the lower magnets. The lower magnets have opposite polarities to the upper magnets and can be attracted.

The cover plate is in an inverted L shape, the cover is arranged on the pressing block, a cover plate pressing structure is installed on the base, and a pressing block pressing structure is installed on the cover plate.

In this way, when the embroidery cloth 8 is tensioned, one end of the embroidery cloth is placed on the base, the pressing block is placed on the embroidery cloth, the upper magnet and the lower magnet are attracted to clamp the embroidery cloth, and then the end of the embroidery cloth is folded back onto the pressing block, the cover plate is placed on the pressing block, the position of the cover plate is fixed by the cover plate pressing structure, and the pressing block is pressed by the pressing block pressing structure. The cloth clamping device can realize the double pressing of the embroidery cloth, has high stability, and is easy to use.
