Description

Technical Field

[0001] This utility model relates to the field of automatic sewing machine technology, and in particular to an automatic sewing machine for processing underwear back buckles. Background Technology

[0002] Sewing machines are mainly used for sewing fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. They produce neat, beautiful, flat, and strong stitches, are fast, and easy to use. They have also given rise to art forms such as hand-pushed embroidery and computer embroidery. However, current sewing machines are still mainly operated manually, which leads to low efficiency and poor precision. Therefore, it would be best to automate them, which would not only reduce labor intensity but also improve efficiency and sewing results.

[0003] The bra back clasp is an important component of the bra structure. It allows the wearer to adjust the bra's tightness according to their individual body shape, ensuring comfort and a snug fit. It also facilitates putting on and taking off the bra. Currently, bras are made by sewing the bra back clasp onto the bra using a sewing machine. However, during the sewing process, the bra back clasp needs to be manually positioned before the sewing machine is used to sew the overlapping area between the bra back clasp and the bra. This process is not only inefficient but also poses a safety risk due to the complexity of the operation and the risk of workers being injured by the sewing machine while manually pressing and positioning the bra back clasp.

[0004] Therefore, we propose an automatic sewing machine for processing underwear back clasps. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic sewing machine for processing underwear back buckles.
