Abstract

The invention provides a thin and thick material detection device, a sewing machine control system and a method. The thin and thick material detection device includes: a detection part arranged by rotation, the detection end of the detection part is placed above the sewing table, and the gap between the detection part and the sewing table is as follows: The thickness of the cloth to be sewn, when the thickness of the cloth to be sewn changes, the detection part is driven to rotate; the signal generating mechanism includes an inductor for sensing whether the detection part rotates and/or the magnitude of the rotation, and is connected to the sensor And it is a signal generator that sends out the variable generated by the sensor as different signals. The present invention avoids the phenomenon of jamming when sewing over-thickness and over-stemming and sewing at different rotational speeds with different thicknesses of fabrics, which can well solve the problem of poor sewing stitches in the state of continuous sewing of thin and thick fabrics and sewing of thick fabrics question.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a thin and thick material detection device, a sewing machine control system and a method. Background technique [0002] Existing sewing machines always maintain a certain rotational speed for sewing during the sewing process. When threading and sewing heavy materials, the rotational speed cannot be adjusted, and the original rotational speed is continuously maintained for sewing, which produces a series of sewing machine performance. Reduced, poor sewing quality, reduced machine life, and often the situation of too thick and stuck cloth. Therefore, it is necessary to control the rotation speed of the sewing machine in real time according to the change of the thickness of the fabric, so as to prevent the phenomenon of over-stem jamming. [0003] Chinese patent 201510586905.6 discloses a sewing machine and a control method of the sewing machine. The sewing machine can cont...
