Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting machine technology, specifically to a roll feeding mechanism and a die-cutting machine. Background Technology
[0002] Die-cutting is one of the most common processes in packaging and printing. A die-cutting machine uses die-cutting blades to assemble a die-cutting plate according to the product design requirements. Under pressure, it cuts the printed material or other coiled blanks into the desired shape or creates creases. Creasing, on the other hand, uses crease cutters or crease dies to press creases onto the sheet material under pressure, or uses rollers to bend the sheet at predetermined positions. Typically, die-cutting and creasing combine the die-cutting blade and crease cutter within the same template, performing both die-cutting and creasing simultaneously on a die-cutting machine; this is simply called die-cutting. The main processes of die-cutting and creasing are: plate mounting, pressure adjustment, alignment, pasting of substrate and auxiliary materials, trial die-cutting, formal die-cutting and creasing, waste removal, and finished product winding or cutting into sheets and counting for packaging.
[0003] In existing die-cutting machines, the feeding mechanism is used to fix the roll-shaped strip material. However, due to differences in the number of windings, the height of the roll-shaped strip material varies. When the feeding mechanism cannot adjust to the height of the roll-shaped strip material, the conveying angle of the strip material changes significantly during feeding, causing the strip material to move back and forth, resulting in jumping and twisting, which affects the die-cutting quality. Therefore, there is an urgent need to develop a roll feeding mechanism and die-cutting machine to meet the needs of practical applications. Utility Model Content
