AI Technical Summary
Existing bag-making machines require frequent changes to the die and folding knife components when dealing with bag-shaped fabrics of different thicknesses and sizes, resulting in low production efficiency and complex operation, making it difficult to achieve efficient bag folding and forming.
The die-cutting device with a split structure includes multiple adjustable unit dies and folding knife assemblies. Through the linkage of the screw mechanism and mechanical transmission, the die-cutting device and folding knife can be automatically or manually adjusted to adapt to changes in the thickness and size of bag-shaped fabrics.
The process of debugging the die and folding knife components has been simplified, improving production efficiency, reducing operational difficulty, and ensuring the best forming effect of pocket folding.
