Abstract

The invention provides an over-step speed reducer of a sewing machine. The over-step speed reducer of the sewing machine comprises an electric control module of the sewing machine, a main motor for driving the sewing machine to operate, a presser foot seat and a presser foot plate, and further comprises a pressure spring and a pressure sensor fixed on the presser foot plate, wherein one end of the presser foot plate is a feeding end, the presser foot plate is hinged to the lower end of the presser foot seat and is provided with a fixed swinging fulcrum, the upper end and the lower end of thepressure spring are separately butted to the presser foot seat and the pressure sensor, and the main motor and the pressure sensor are both connected with the electric control module; and the pressuresensor, the fixed swinging fulcrum of the presser foot plate and the feeding end of the presser foot plate are sequentially arranged from front to back along the feeding direction of forward feedingof the sewing machine. In the sewing process, the electric control module can judge whether it passes through steps or not during sewing in real time through the output signal of the pressure sensor,and when it passes through the steps during sewing, the electric control module immediately controls the sewing machine to reduce the speed for sewing, so that the speed of the sewing machine is reduced in time, speed reduction delay does not exist, thread breakage, needle breakage and the like can be effectively avoided, and finally the sewing quality is guaranteed.

Description

technical field [0001] The invention relates to a sewing machine stem passing deceleration device. [0002] The present invention also relates to a method for controlling the stem passing deceleration of the sewing machine comprising the above sewing machine stem passing decelerating device. Background technique [0003] In the process of sewing fabric, the sewing machine will sew over the steps when the thickness of the fabric becomes thicker. At this time, it is necessary to reduce the sewing speed of the sewing machine, that is, slow down when passing through the stem. At present, the speed reduction is mainly controlled by workers, or a detection device for detecting the thickness of the fabric is installed in the sewing machine, and the electronic control module of the sewing machine controls the speed reduction of the sewing machine according to the thickness of the cloth fed back by the detection device. However, there is a problem of lagging in speed reduction in th...
