Benefits of technology

[0015] The aforementioned embroidery thread tension control system, through the coordinated arrangement of a fixed wheel assembly, several movable wheel assemblies, a thread length measuring assembly, and an embroidery thread pressing assembly, allows the thread length measuring assembly to detect the current consumption of different colored embroidery threads in a pattern in real time and send it to the control module. The control module then determines the difference between the current consumption of different colored embroidery threads in the same pattern and the preset consumption. Based on this difference, the control module sends a control signal to the embroidery thread pressing assembly. The embroidery thread pressing assembly drives the movable wheel assemblies corresponding to different colored embroidery threads to move closer to or further away from the fixed wheel assembly at the corresponding position. By determining whether the tension of the embroidery thread is appropriate based on the difference between the current consumption of different colored embroidery threads and the preset consumption, the embroidery thread tension can be dynamically adjusted to ensure the quality of the embroidery.

Abstract

The application discloses an embroidery thread tension control system of an embroidery machine, which is characterized by the cooperation of a fixed wheel assembly, a plurality of movable wheel assemblies, a thread length measuring assembly and a thread pressing assembly. The thread length measuring assembly detects the current consumption of different color embroidery threads in a pattern in real time and sends the current consumption to a control module. The control module judges the difference between the current consumption and a preset consumption of different color embroidery threads in the same pattern. The control module sends a control signal to the thread pressing assembly according to the difference. The thread pressing assembly drives the movable wheel assemblies corresponding to different color embroidery threads to move close to or away from the fixed wheel assemblies at corresponding positions. Whether the tension of the embroidery thread is appropriate at the moment can be judged according to the difference between the current consumption and the preset consumption of different color embroidery threads, so that the tension of the embroidery thread is dynamically adjusted to ensure the quality of the embroidered product.
