Description

Technical Field

[0001] The utility model relates to the technical field of overlock machines, in particular to a full-automatic overlock machine. Background Art

[0002] Overlocking, also known as lock edge, is a term in the clothing industry. It refers to using an overlocking machine to overlock the edge of the cut fabric, so that the silk threads at the cut fabric are not easy to unravel, and at the same time it has the effect of beautifying the cut fabric.

[0003] The existing patent (publication number: CN214831043U) discloses an auxiliary feeding device for an overlocking machine. After the cloth is laid on the feeding table and aligned with the needle bar, the mounting frame is slid down until the push roller is pressed against the cloth and then the overlocking machine is started for overlocking. The cloth pressed against the push roller is not prone to lateral movement, which improves the straightness of the overlocking of the cloth and improves the production qualification rate of the cloth.

[0004] When the above patented technology is in use, due to the different widths of different fabrics and the fixed cylinder being fixedly installed on the feeding table and not easy to move, the wider fabric interferes with the fixed cylinder when moving, causing the fabric that touches the fixed cylinder to wrinkle due to pressure, thereby reducing the quality of the fabric. Therefore, a fully automatic overlocking machine is proposed. Utility Model Content
