Description

[0002] As a commonly used advertising and decorative material, the production process of light box cloth usually includes spreading, conveying, edge cutting and trimming, and final winding. In the traditional production process, these links often rely on multiple independent devices or a large number of manual operations, which has obvious efficiency bottleneck.

[0003] Firstly, the traditional edge cutting process has low automation degree, and usually needs manual guidance and cutting. This way not only has high labor intensity and low production efficiency, but also the stability of manual operation is difficult to guarantee, which easily causes the edge of the cloth to have problems such as wavy shape, burr or unevenness due to deviation of cutting force or path, seriously affecting the quality and consistency of the product.

[0004] Secondly, the tension control of the cloth during conveying is a key difficulty. Without effective real-time tension adjustment mechanism, the cloth may be loose or tight during processing. If too loose, the cloth will sag and wrinkle, affecting the normal work of the cutting knife and the cutting accuracy; if too tight, the cloth may be accidentally stretched or even torn, causing material waste and increasing the rate of defective products.

[0005] In addition, the treatment of waste cloth strips generated during the cutting process is also a big problem.
