Research And Design Of The Critical Process Of Test Paper Bag Sealing And Printing

The research and development of test paper bag sealing,seal the key technology of customized printing,automatic pasting sealing and automatic production equipment of integrated innovation form greatly improve the production efficiency or level,product quality and stability.Especially the seal by online custom printing,a paper test paper bag with a seal to prevent the leakage of the seal and replacement,to achieve the uniqueness of the paper bag security,Enhance the innovation ability of enterprises,while the development of products can significantly enhance the market competitiveness of enterprises.at present,the research and design of test paper bag sealing printing and automatic sealing technology are still in the blank stage,Mainly because the test paper bag sealed printing and automatic bonding equipment is non-standard equipment,social demand is not too large,up to now,the country has a total of 23 printing companies to obtain national security certification.because the population of Abroad base is not very large,and the same exam can be held many times a year,the using of digital equipment for examination,Such as the candidate through examination end computer to access the server computer,However,China’s population base is particularly large,hardware equipment can’t requirements of the examination,therefore,the need for printing papers for examination.the test paper bag seal custom printing and automatic belong to the complex mechanical and electrical integration equipment.through the investigation and study to determine the main process,the using of TRIZ theory to achieve the current process of institutional innovation,to find a more appropriate body,and key institutions or parts of the simulation analysis.First of all,the test paper bag sealing and customization process analysis,the main process,summed up the current package of the main package to bring a series of problems,with the support of government policy and the development of automation,the research can complete the test paper bag seal customization and automatic sealing process.Secondly,we find out the improvement of the parameters and the deterioration parameters based on the contradiction matrix of TRIZ theory,and use the inventive principle to innovate the mechanism,And through the three-dimensional modeling software Pro/e to complete the modeling.The mathematical formulas of the rigidity of some key parts,such as the cylinder of the printing press are deduced.Furthermore,the software simulation is carried out according to the design of the mechanical mechanism or the key parts.In particular,The relationship between the cylinder wall thickness and the cylinder interference,Static analysis and modal analysis of cutting blade of cutting mechanism,Simulation analysis of gripper mechanism.this paper has a certain reference value for the study of paper bag sealing and automatic laminating.
