Analysis of the automatic thread break detection system of SHJ-P Weft Feeder

Working principle of the automatic thread break detection system
The photoelectric detection system equipped with SHJ-P Weft Feeder is an efficient automatic thread break detection technology. The system monitors the status of the yarn in real time through precise photoelectric sensors, and can quickly and accurately detect the moment of yarn breakage. Once the system finds that the yarn is broken, it will immediately sound an alarm and automatically stop supplying, avoiding production stagnation or fabric defects caused by continued operation of the broken thread.

Real-time monitoring and high-precision detection:
The photoelectric sensor adopts a non-contact detection method, which can accurately capture the state changes of the yarn under high-speed operation. Whether it is the breakage of the yarn or the relaxation of the yarn caused by uneven tension, the system can respond in a very short time, avoiding the impact of the breakage on subsequent production.

Automatic response and control:
Once the yarn is broken or abnormal, the photoelectric detection system will respond immediately, automatically stop supplying and trigger an alarm. This mechanism can not only cut off the bad links in production in time, but also reduce manual intervention and reduce the risk of human operation errors.
Advantages of automatic thread break detection

Improve production stability:
The automatic thread break detection system monitors the running status of the yarn in real time to ensure that the supply can be stopped quickly when the thread break occurs, avoiding the thread break from continuing to pull the yarn in other parts, resulting in serious breaks or messes in the fabric. This not only reduces downtime, but also ensures the stability of the production process. Especially when weaving at high speed, this system can greatly reduce the downtime caused by thread breakage.

Optimize fabric quality:
In textile production, thread breakage is often one of the main causes of fabric quality problems. The automatic thread break detection system of SHJ-P Weft Feeder can avoid fabric defects caused by untimely detection of thread breakage. For example, uneven weave patterns or defects may appear on the surface of the fabric due to thread breakage, which are unacceptable in the production of high-quality fabrics. The automatic thread break detection system can effectively eliminate this problem and ensure that the quality of each batch of fabrics meets the expected standards.

Reduce manual intervention and operating errors:
Traditional thread break detection methods often rely on manual operation. Once a thread break occurs, the operator needs to detect and handle it in time. However, in high-speed production, the manual reaction speed is difficult to match the running speed of the equipment. The automatic thread break detection system can automatically identify thread break problems and stop supply in time through intelligent control, which greatly reduces the frequency of manual intervention, reduces the workload of operators, and reduces the risk of errors caused by improper operation.
Application Examples and Industry Significance
The automatic thread break detection system of SHJ-P Weft Feeder has played a huge role in actual production, especially in the process of high-speed weaving, which can maintain a continuous and stable yarn supply. For example, when producing high-end fabrics, thread break problems may cause obvious defects on the surface of the fabric. Through automatic thread break detection, the system can instantly identify and interrupt the supply, avoiding adverse effects and ensuring the uniformity and smoothness of the fabric.

In addition, in large-scale production, the automatic thread break detection system can reduce downtime and improve the overall efficiency of the production line. In some special industries, such as automotive seat fabrics, military fabrics and other fields with extremely strict quality requirements, this function of SHJ-P Weft Feeder is particularly important, which can ensure the high quality of each batch of products and meet the high standards of customers.
