【摘要】：随着人们物质生活的提高，包装印刷越来越被人们所重视，从而模切机也走上了快速发展的道路。模切机是印后包装加工成型的重要设备，起到增加产品附加值的作用。模切机是由送纸部分，模压、烫印部分，清废部分，堆垛部分，间歇输纸机构等组成的；其中模压、烫印部分的是自动平压平模切机的核心部分，其传动机构机械运动性能的好坏对模切机的性能起着至关重要的作用。到目前为止，模切机生产厂家生产的大部分模切机都是使用双肘杆机构作为模压、烫印部分的传动机构，其特性对提高整机的速度和稳定性具有至关重要的影响。首先，对平压平模切机做了初步描述，又对其国内外发展现状以及研究成果做了简要的论述。其次，对模切机的各个单元的执行机构做了简单的阐述，还对影响模切机加工精度、加工速度以及整机的稳定性、可靠性等性能的因素做了简要解说。最后，以模切机双肘杆机构为研究对象，从模切压痕工艺和模切机动平台运动稳定性的角度出发，对现有模切压痕系统进行了分析，，结合现有模切机型在使用过程中存在的问题，在前人研究的基础上提出了一种新型主切机构。用ADAMS对双肘杆机构和新型主切机构分别进行了仿真分析，通过对比可以看出，与双肘杆机构相比，新型主切机构不但具有较好的稳定性，而且保压时间也明显变长，从而具有更好的工艺性。为使整个机构在具有运动稳定性高和模切压痕工艺性好的基础上达到一个最佳的平衡，还对新型主切机构进行了优化设计。如果本课题的研究成果能够被厂家采用，进而进入产业化阶段，不但模切机的寿命能够得到一定的提高，而且能够扩大其加工范围，给企业带来更好的经济效益。
[Abstract]:With the improvement of people's material life, packaging and printing are paid more and more attention. Die-cutting machine is an important equipment for post-printing packaging processing and forming, and plays a role in increasing the added value of products. The die cutting machine is composed of the feeding part, the pressing part, the hot stamping part, the waste cleaning part, the stacking part, the intermittent paper feeding mechanism and so on, among which the die pressing and hot stamping part is the core part of the automatic flattening die cutting machine. The mechanical movement performance of its transmission mechanism plays an important role in the performance of die cutting machine. Up to now, most die-cutting machines produced by die-cutting machine manufacturers use double-elbows mechanism as the transmission mechanism of die pressing and stamping part. Its characteristics have a vital effect on improving the speed and stability of the whole machine. First of all, a preliminary description of flat die cutting machine is given, and the present situation and research results at home and abroad are briefly discussed. Secondly, the execution mechanism of each unit of the die cutting machine is briefly described, and the factors affecting the machining accuracy, processing speed, stability and reliability of the die cutting machine are also briefly explained. Finally, taking the double elbows mechanism of die cutting machine as the research object, the existing die cutting indentation system is analyzed from the angle of die cutting indentation technology and motion stability of die cutting platform. A new type of main cutting mechanism is proposed on the basis of the previous research, combined with the problems existing in the use of the existing die cutting machine. The double elbow bar mechanism and the new main cutting mechanism are simulated by Adams. The comparison shows that compared with the double elbow bar mechanism, the new main cutting mechanism not only has better stability, but also has a longer holding time. Thus has better craft. In order to achieve an optimal balance on the basis of high motion stability and good die cutting indentation process, the new main cutting mechanism is also optimized. If the research results of this subject can be adopted by the manufacturers and then enter the industrialization stage, not only the life of the die cutting machine can be improved, but also the processing range can be expanded, and better economic benefits will be brought to the enterprise.
