Sewing machine and security protection device for application of sewing machine

Abstract

The invention provides a sewing machine and a security protection device for application of the sewing machine. The sewing machine comprises an infrared sensor, a processor, a driving unit, an electromotor and a position detection unit, wherein the processor is electrically connected with the infrared sensor; the driving unit is electrically connected with the processor; the electromotor is electrically connected with the driving unit; the position detection unit is electrically connected with the processor and the electromotor. According to the sewing machine, whether fingers of operators approach to the machine can be sensed by the infrared sensor, when finger approaching is sensed, the electromotor can be locked in a present position, then the electromotor cannot be started to hurt fingers even if a pedal is trodden by the operators by mistake when the fingers of the operators approach to the infrared sensor.

AI Technical Summary

Benefits of technology

This patented technology includes two parts - one part involves detecting humans' touch by means like an infraviolet light or other type of sensor that can help prevent accidents caused by operators who step their foot incorrectly onto them during operation. Another aspect relates to locking up certain motors while they are still running properly for better performance.

Problems solved by technology

This technical issue addressed by these inventions relates to improving the security and usability (user experiences) provided during sewage knitting operations while reducing potential harm from human error such as falsely cutting threads that could cause injury through incorrect manipulation. Additionally, existing designs require heavy motor systems, leading to increased stress levels over longer periods of use.
