Abstract

The invention provides an overedger shield safety switch structure. The overedger shield safety switch structure comprises a shell and a protecting cover used for protecting a line crossing rod and a needle rod. The protecting cover is pivoted on the shell, and a safety switch enabling an overedger to stop when the protecting cover is opened is arranged between the protecting cover and the shell. The invention further provides an overedger shield safety protecting method. The openable protecting cover used for protecting the line crossing rod and the needle rod is arranged on the shell of the overedger. The overedger shield safety protecting method includes that when the protecting cover is opened, the safety switch on the protecting cover transmits a signal to a control system which forbids the overedger to start; when the protecting cover is closed, the safety switch transmits a signal to the control system which allows the overedger to be started. By arranging the safety switch between the protecting cover and a frame, the overedger shield safety switch structure and the overedger shield safety protecting method have the advantages that the overedger cannot be started even by misoperation of a maintainer who is threading a line and changing a needle, so that the maintainer is prevented from being injured, and damage to a machine is avoided.

Description

technical field [0001] The invention relates to a safety switch structure of an overlock sewing machine shield. [0002] The invention also relates to a safety protection method for the shield of the overlock sewing machine. Background technique [0003] Overlock sewing machine is one of the main sewing equipment of garment enterprises. It is used to trim and sew the edges of fabrics in garment processing, and wrap the edges of fabrics with specific stitches to prevent the yarns of the fabric from falling apart. The types of overlock sewing machines are divided into single thread, double thread, three thread, four thread, five thread and six thread according to the number of threads. Among them, the single-thread overlock sewing machine adopts a straight needle, two fork needles and a suture to form a single-thread overlock stitch, which is mainly used for sewing fur and cloth joints; the double-thread overlock sewing machine adopts a straight needle, a A looper, a fork ne...
