Abstract: In the drive of market demand, postpress equipments developing rapidly. Because of environmental protection and energy saving, pre-coating technology has broad application prospects. But in China, the design of the machine are mostly generic and doesnt have a set of perfect design theory. There is no design innovation from the source. Using virtual prototype technology, the structural design of the key components of the pre-coated laminating machine to the paper feed mechanism is improved. Through the three-dimensional modeling, assembly and disassembly, adjustment mechanism simulation, motion simulation of mechanism, the physical, mechanical performance analysis, simulation, prediction, realizes fast implementation and optimization design, improves the processing and assembly technology.

Abstract: The digital inkjet CTP (Computer to plate) device is one of printing equipments that urgently needs to be reseached and invented in China. Based on the current situation for computer inkjet plate-making devices widely used in the market, this thesis introduces work principle and system composition for inkjet CTP device, mainly from from the mechanical perspective to introduce structural composition of inkjet CTP device. By taking the example of some naked plate of inkjet CTP device, the sample of fabricated machine is studied for the composion of each mechanism in mechanical parts.

Abstract: In order to learn more about the working performance and dynamic characteristics of it, a new die-cutting experimental platform drove by gas-liquid pressurization system. To use the AMESim software simulates and analyzes this platform. The simulation results showed the velocity, output force and displacement of gas-liquid pressurization system. The output force of this system can meet the requirement of die-cutting press, and two stages of the velocity remain relatively stable as it moved. The operating characteristic analysis of die-cutting experimental table not only contributes to knowing about its running state, but also provides the basis for designing the die-cutting machine driven by the gas-liquid pressure cylinder.

Abstract: Aiming at the reuse of design knowledge, this paper proposes knowledge reuse technology for product design of printing press which is based on rule and case. An integrated software package with SQL Server which is Database Management System (DBMS) and VisualC++6.0 which is a kind of development tools has been developed. This software may be embedded in the environment of Solidworks to assist the designer to index correlative design knowledge and develop new product of printing press after modification.
