Template sewing machine achieving automatic adjustment of thread tension

Abstract

The invention discloses a template sewing machine with achieving automatic adjustment of thread tension. The template sewing machine comprises a station platform, a machine head, a plate clamping device, a longitudinal groove, a moving beam and a sliding block. The template sewing machine is characterized in that the machine head is provided with an electromagnetic tension adjustor and a thread tension sensor, the electromagnetic tension adjustor comprises a thread clamping disc, an installing screw, an electromagnetic coil and an armature, and the thread tension sensor and the electromagnetic coil are connected with a control unit of the template sewing machine. Compared with the prior art, the template sewing machine has the advantages that the electromagnetic coil and the thread tension sensor are connected with the control unit of the template sewing machine, the current threading speed is read through the control unit, the range where the tension should be controlled is estimated, and then the thread tension can be measured in real time through the thread tension sensor; the current of the electromagnetic coil is adjusted in time by comparing the pre-judged tension value with the real tension value in real time, and therefore the intelligent and automatic control over the thread tension is achieved.

Description

technical field [0001] The invention relates to the field of garment processing equipment, in particular to a template sewing machine with automatic adjustment of suture tension. Background technique [0002] The template sewing machine designs the sewing template according to the process of each part of the garment, then places the sewing template on the sewing machine, and automatically and efficiently completes the sewing according to the process standard. It is widely used in the current garment production. Through the use of sewing templates and the reasonable arrangement of the assembly line, garment factories can reduce their dependence on skilled workers, solve technical bottlenecks, improve sewing efficiency, ensure uniform quality of sewn products, and provide positive assistance for batch and standardized operations. [0003] At present, the sewing machines generally used in industrial sewing, in order to make each sewing thread smoother, a tension adjustment devi...

AI Technical Summary

Problems solved by technology

However, this method will be inconvenient to adjust due to the setting of the suture tension adjustment device in application. During the sewing operation, when the operator finds that the tension of some sutures is too loose or too tight and needs to be adjusted, Adjustments must be made manually, making them extremely inconvenient

Furthermore, due to the lack of timely adjustment, defective products are often produced, especially for unattended template sewing machines, which often cause great losses when they are discovered, resulting in the inability to automatically complete the sewing operation.

The scheme of pre-setting the tension value by pure program calculation cannot be adjusted according to the actual working conditions, and the effect of intelligent adjustment cannot be achieved.
