Abstract


This article is based on front gauge positioning mechanism and the chain transmission system which Influence on positioning-precision of paper feeding assembly of MW1050 Automatic mould-cutting machine produced by Shanghai Yahua Printing Machine Ltd. The main contents and innovations are as follows:1. It has analyzed kinematical principle of movable carriage and relation between front gauge positioning mechanism and movable carriage, pointed out kinematical principle of front gauge positioning mechanism. This provides the foundation for the dynamics analytics.2. It has made use of the centralized mass method to get dynamics model of front gauge positioning mechanism, get dynamics response and dynamics kinematics error, studied that front gauge have influence on the positioning accuracy of paper-feeding gripper.3. It has been built a testing system of actual running state of the mechanism which is applied to a MW1050 Automatic mould-cutting machine to measure actually and gets actual kinematical principle of front gauge positioning mechanism. Pass the contrast, verify the possibility of thedynamic model established in theories analysis.4. Conduct kinematics and dynamic analysis and study on the chain transmission of follower system, establish vibration model of the chain pitches and the gripper bars, and also find out the free vibration frequency and point out factors influencing the precision of location of the chain transmission system.Pass research of this article , it not only provide certain theories analysis and practical optimal method for improvement of mould-cutting machine, but also provide a method for usher of equipments in printing machine factories, and lay a foundation for further development of running state inspecting system of the device.
