Improvement of the drive mechanism of the pressure plate of the flat die-cutting press

The main advantages of the most common method of manufacturing cardboard packaging are given. The classification of the die-cutting equipment for the production of cardboard packaging according to the shape of the contacting surfaces is given, with a description of the principle of their operation. The principle of die-cutting cardboard blanks in packaging equipment for flat, flat-cylindrical and rotary methods is depicted. The main advantages of the flat die-cutting, as the most popular in the world, are presented, The negative consequences caused by the oscillating movement of the pressure plate in the flat die-cutting equipment are listed. The drive mechanisms of the movable pressure plate of the flat die-cutting presses, which ensure strictly vertical movement of the pressure plate, are analyzed. The main disadvantages are shown. A new drive mechanism of the movable pressure plate of the flat die-cutting is proposed, which consists of left and right rockers; rollers that are fixed on sliders that move along horizontal guides; cams, with which the rollers are in constant contact with the help of springs. A structural diagram with a description of the proposed drive mechanism is given. The principle of operation of the die-cutting machine press, which contains the proposed drive mechanism of the movable pressure plate, is described. The advantages of the proposed drive mechanism are listed. Recommendations for the manufacture of cams and rollers for the proposed drive mechanism are described. The structure of the analytical research for the proposed drive mechanism of the movable pressure plate of the flat die-cutting press is presented.

Keywords: drive mechanism, flat die-cutting press, movable pressure plate, structural scheme, packaging, cams, rollers.
