Description

Technical Field

[0001] This utility model relates to the field of gold leaf embroidery technology, and in particular to an adjustable paddle structure and a feeding device. Background Technology

[0002] The sheet feeder includes a base plate with a sheet feeding groove, a lever that cooperates with the sheet feeding groove to feed the gold sheets, a drive linkage connected to the lever, and a transmission rod on the drive linkage. The gold sheets are a series of perforated thin sheets embroidered onto fabric for decorative purposes. A lever protrusion is located below the lever, and the sheet feeding groove has a lever groove that cooperates with the lever protrusion. The lever protrusion passes through the holes in the gold sheets, driving the gold sheets to feed.

[0003] In existing technologies, the drive linkage is typically fixedly connected to the corresponding connecting shaft via bearings, preventing lateral movement of the drive linkage. The paddle lever is also fixedly connected to the drive linkage, making its position unadjustable. During manufacturing, a spacer ring of fixed dimensions is placed between the two feeders. Errors can occur during the manufacturing of this spacer ring, especially in multi-sheet feeding devices. These accumulated errors can cause the paddle lever to easily shift out of the paddle slot, affecting sheet feeding. Assembling, replacing, and maintaining the paddle lever is also inconvenient.

[0004] In addition, due to processing errors, the drilling position of the gold sheet may be deviated. Since the lever is mounted on the corresponding connecting shaft along with the drive linkage, it generally cannot move left or right. This means that the lever protrusion may not be able to accurately insert into the gold sheet hole, especially for gold sheets with smaller holes, which will affect subsequent sheet feeding. Utility Model Content

[0005] To address the problems of the prior art, this utility model provides an adjustable paddle structure and a feeding device. The adjustable structure allows for adjustment of the paddle lever's position, centered on the lever, resulting in more accurate feeding.
