[0002] Die-cutting is one of the most commonly used processes in packaging printing, with widespread applications in food, pharmaceuticals, tobacco, and many other fields. Die-cutting machines, as essential equipment in post-printing packaging processing, are mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste removal of non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc. With the development of the printing and packaging industry, the market has placed higher demands on the performance and quality of die-cutting machinery.
[0003] Traditional die-cutting machinery has several shortcomings. Some machines have inefficient loading and unloading methods, requiring frequent manual operation and resulting in low production efficiency. Furthermore, the positioning and movement of the blades in traditional die-cutting machines are not precise enough, easily leading to die-cutting quality problems and failing to meet the high-precision requirements of modern packaging and printing. Some die-cutting machines rely on manual labor for cardboard feeding and positioning, which is complex, labor-intensive, and prone to inaccurate positioning, affecting overall production efficiency. Traditional die-cutting machines may pose safety hazards during blade reset, potentially causing accidental injury to operators. In addition, the equipment may vibrate during high-speed operation, affecting die-cutting quality, and lacks effective sound insulation, resulting in a noisy working environment.
