Embroidery machine trimming method

Abstract

The invention discloses an embroidery machine trimming method, and belongs to the technical field of embroidery machines. The embroidery machine trimming method is applied to a control end of an embroidery machine and comprises the following steps that step S10, a machine needle is controlled to drop, and an upper thread end is brought to a position below a needle plate; S20, after the upper thread end is brought to the position below the needle plate, a thread trimming movable knife is controlled to hook the upper thread end to move towards the thread trimming fixed knife until the thread trimming movable knife and the thread trimming fixed knife are stopped from being limited when not closed, at the moment, the hooked upper thread is limited to a bottom thread retainer below the thread trimming movable knife; S30, the machine needle is controlled to lower to complete embroidery of at least one stitch; and S40, the thread trimming movable knife is controlled to move from the stop limit to the thread trimming fixed knife, and the upper thread end is cut off when the thread trimming movable knife and the thread trimming fixed knife are closed.
