technical field

The utility model relates to the technical field of die-cutting machines, in particular to an intermittent conveying die-cutting mechanism of a die-cutting machine.

Background technique

The semi-automatic flat die-cutting machine is a special equipment for pressing paper products such as cartons and cartons in the printing and packaging industries. It can creasing, tangent, embossing embossing on cardboard of various specifications, corrugated cardboard with a thickness below 4mm, and various high-grade and fine printed matter. After indentation and tangent cardboard, after removing the edge material along the tangent line by hand or machine, it can be folded into various cartons and cartons along the indentation, or made into concave and convex trademarks. There are two main technological actions. One: one is to feed the cardboard in place, and the other is to punch and die-cut.

When the die-cutting machine stamps and die-cuts the cardboard, it is necessary to temporarily stop the paper feeding device. The existing die-cutting machines often use servo motors for intermittent control of the paper feeding device, which is costly, and the paper feeding device and There is no linkage control between the die-cutting devices. If the die-cutting device breaks down and the paper feeding device continues to work, it will cause the cardboard that has not been die-cut to enter the next process, affecting production.
