Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment, and particularly relates to a spring material clamping device for a sequin embroidery machine. Background Art
[0002] The clamping device of the embroidery machine is generally used to fix the cloth during embroidery, so that the cloth is always in a flat state, making it easier for the machine to embroider exquisite patterns. At present, the clamping structure of the embroidery machine generally uses a convex cloth pressing strip. After the embroidery cloth is spread, the cloth pressing strip is manually pressed against the frame with the concave cloth clamping groove to clamp it. However, in the actual embroidery process, the embroidery cloth is subjected to pressure, and the pressure will continue to increase. The embroidery cloth is easy to slide out of the concave cloth clamping groove. If the convex cloth pressing strip exerts a large force on the concave cloth clamping groove, the cloth is easily damaged when the convex cloth pressing strip is taken out. The existing cloth clamping device cannot ensure that the embroidery cloth is clamped, and it is easy to damage the embroidery cloth, thereby affecting the embroidery quality. Utility Model Content
[0003] The utility model provides a spring material clamping device for a sequin embroidery machine which has a simple structure, is convenient to use and has a stable clamping force.

[0005] Furthermore, the torsion spring assembly includes a cloth clamp torsion spring, the cloth clamp torsion spring is connected to the first adjustment plate through a second screw, and the first adjustment plate is connected to the fixed material clamp through a first screw.
[0006] Further, the spring buckle assembly includes a spring buckle base, the spring buckle base is connected to a second adjustment piece via a fourth screw, the spring buckle base is connected to a spring buckle via a second connecting rod, both sides of the spring buckle are connected to second spring buckle supports via a third connecting rod, both sides of the second spring buckle supports are connected to first spring buckle supports via springs, and the first spring buckle supports on both sides are connected to the first connecting rod.

[0012] Through the setting of the spring buckle assembly, the first connecting rod is buckled with the arc-shaped protrusion, and the compression force of the spring increases the clamping force between the movable material clamp and the vertical clamp plate to achieve a compressed state.
