Конструктивно-технологічні особливості плоскоциліндрового преса для штанцювання розгорток картонних паковань

The modern paperboard packaging market is undergoing significant changes due to growing demand, high competition, and requirements on environmental friendliness and product qualitys. Paperboard packaging occupies more than a third of the global market, emphasising its economic significance. However, traditional, widely used flatbed die-cutting presses have sev-eral drawbacks: high- energy consumption, difficulty in setting up and uneven load distribution, which decreases processing accuracy and packaging quality. These drawbacks limit production efficiency and increase product costs, making the search for alternative technical solutions relevant.The main problem is the need to develop new designs of die-cutting presses that would eliminate the drawbacks of existing systems, in particular, ensure even loading, reduce energy consumption and increase productivity while maintaining quality. Flat-cylinder presses demonstrate prospects of this approach.The study aims to develop a scheme for a flat-cylinder die-cutting press with a reversible drive mechanism that increases efficiency of manufacturing paperboard packaging cut-outs.The work shows a detailed kinematic scheme of the press, including the mechanism of the reverse movement of the pres-sure cylinder. The proposed scheme uses a stationary die-cutting form and a movable pressure cylinder, providing consistent pressure and reducing energy consumption. The key innovation is the drive mechanism, which allows die cutting during the cylinder's forward and reverse strokes.The proposed flat-cylinder die-cutting press is a promising solution for the packaging industry, as it combines advantages of different types of equipmen, namelyt: versatility of flat presses, energy efficiency of rotary systems and high productivity due to double-sided die-cutting. Iintroduction of these presses will provide for optimisation of production processes, reducing the cost of production and increasing its competitiveness in the market. Further research may be aimed at improving automation systems and adapting the press to work with different types of cardboard materials.
