Problems solved by technology

[0003] The industrial sewing machines in the prior art cannot detect the thickness of the fabric in advance when the thickness of the fabric to be sewn changes, and reduce the sewing speed of the industrial sewing machine, which will lead to uneven sewing and different stitch lengths where the thickness of the fabric is connected, resulting in In case of poor sewing such as fabric wrinkling or flanging

Abstract

The invention relates to the technical field of manufacturing of sewing machines, in particular to an industrial sewing machine. The industrial sewing machine comprises a detection device, and furthercomprises a motor, wherein the detection device is arranged on a machine housing of the industrial sewing machine, and the detection device comprises a sensor and is used for detecting the thicknessof a to-be-sewn fabric and forming a detection signal; an input end of the motor is connected with an output end of a motor controller, and an output end of the motor is connected with a needle of theindustrial sewing machine; an input end of the motor controller is connected with the sensor, and the motor controller is used for receiving the detection signal, regulating the output voltage of themotor controller when the detection signal indicates that the thickness of the to-be-sewn fabric is increased, so that the rotation speed of the motor is reduced, and the sewing speed of the needle is reduced. The industrial sewing machine has the advantages that before the fabric is sewn, the thickness of the fabric is detected, after it is detected that the thickness of the fabric is increased,the sewing speed of the needle can be automatically reduced, and the poor sewing situations, such as wrinkling and flanging of the fabric, can be reduced.

Description

technical field [0001] The invention relates to the technical field of sewing machine manufacturing, in particular to an industrial sewing machine including a detection device. Background technique [0002] Industrial sewing machine (Industrial sewing machine) is a sewing machine suitable for sewing workpieces for mass production in sewing factories or other industrial sectors. Industrial sewing machines are used in factories that require sewing machines for clothing, shoes and hats, etc. [0003] The industrial sewing machines in the prior art cannot detect the thickness of the fabric in advance when the thickness of the fabric to be sewn changes, and reduce the sewing speed of the industrial sewing machine, which will lead to uneven sewing and different stitch lengths where the thickness of the fabric is connected, resulting in In case of poor sewing such as fabric wrinkles or flanging. Therefore, there is a need for an industrial sewing machine that can detect the thick...
