Description

Technical Field

[0001] The present invention relates to the technical field of airbag processing, and particularly to an automatic scribing machine. Background Art

[0002] Currently, in the field of airbag production, it is generally necessary for an operator to first scribe spline lines on the airbag fabric using a template, and then a sewing machine operator sews the required automotive airbag according to the scribed spline lines. With the improvement of people's living standards, more and more families have one or two cars. This has led to a huge demand for automotive airbags. Moreover, the labor cost of enterprises is also increasing.

[0003] In the Chinese patent with the patent number 201820609809.8, an automatic scribing machine is provided. The scribing nozzle moves in the length direction of the fabric through a transverse moving component and moves in the width direction of the fabric through a longitudinal moving component for scribing. The walking trajectory of the scribing nozzle is preset, and the scribing nozzle walks according to the predetermined trajectory. One airbag is processed at a time. After processing, the transfer component vacuum-absorbs the material and moves the material to the fabric blanking area to complete the scribing work of the airbag. However, this device needs to perform loading and unloading work uniformly, and it needs to stop during loading and unloading, which greatly affects the work efficiency and has certain limitations. Therefore, it is necessary to design an automatic scribing machine to solve this problem. Summary of the Invention
