A Template Sewing Machine with Automatic Adjustment of Suture Tension

Abstract

The invention discloses a template sewing machine with automatic adjustment of suture tension, which comprises a station platform, a machine head, a splint, a longitudinal groove, a moving beam and a sliding block, and is characterized in that an electromagnetic tension adjuster and a The suture tension sensor and the electromagnetic tension adjuster include a thread tension disc to install a screw electromagnetic coil and an armature, and the suture tension sensor, the electromagnetic coil and the control unit of the template sewing machine are connected. Compared with the prior art, the present invention has the following advantages: the electromagnetic coil and the suture tension sensor are connected with the control unit of the template sewing machine, so that the current thread speed can be read through the control unit, and the range of the estimated tension should be controlled, and then the suture tension can be set The sensor can measure the tension of the suture in real time, and adjust the current of the electromagnetic coil in time by comparing the predicted tension value with the actual tension value in real time, so as to realize the intelligent automatic control of the suture tension.

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...

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.
