Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, and in particular to a die-cutting machine for printing groove marks on paper boxes. Background Art

[0002] The die-cutting machine for embossing groove marks on paper boxes is a mechanical equipment specially used for processing paper boxes. It is mainly responsible for pressing groove marks and embossing on paper boxes. This equipment plays an important role in the paper packaging industry and can efficiently and accurately complete the forming process of paper boxes. The working principle of the die-cutting machine for embossing groove marks on paper boxes is to use a template carved from a steel knife, steel wire or steel plate, and apply a certain amount of pressure through the embossing plate to roll the cardboard into a specific shape. This process includes die-cutting (pressing the printed product into a single graphic product), embossing (pressing marks or bending grooves on the printed product) and convex and concave embossing (embossing a three-dimensional pattern on the surface of the printed product).

[0003] The existing die-cutting machines for embossing groove marks on paper boxes on the market basically place the paper box board to be processed on the processing platform, and then push the processing platform part forward, and flip it out when taking the material. The operator needs to cooperate to load and remove the materials one by one. This processing method requires the operator to operate frequently, and lowering the processing interval time will make the efficiency worse. Moreover, when the operator leaves for a short time, the processing will be stopped. Therefore, the application efficiency is poor and it is not conducive to saving labor costs.
