Method for automatically shearing braid

The invention discloses a method for automatically shearing a braid. The method comprises the steps that when a braider normally works, a detection module detects the opening and closing states of a chock plug; when the chock plug is closed, the detection module sends alarm information to a taping counting module; the detection module continuously detects the closing situation of the chock plug; whether alarming frequency reaches a nominal threshold value or not is detected; when the alarming frequency reaches the nominal threshold value, the braid is sheared, and the braider stops running; when braid shearing is finished, the taping counting module sends alarm signals to a device keeper. The method is free of manual waiting operation, achieves automatic counting and automatic braid shearing, improves quality, prevents defective goods from flowing into clients, saves time and labor, saves labor cost, is high in automation degree, and greatly improves work efficiency.
