Development And Application Of Online Limited Length Cutting Equipment

The length of online leaf wire is to limit the length of leaf silk in tobacco processing line,so as to meet the requirement of silk making process.Tobacco processing is the first process of tobacco processing.The rationality of its structure is directly related to the quality of cigarette.At present,there is a high proportion of tobacco filaments in tobacco processing enterprises,which has a high proportion of tobacco filament and the low proportion of middle silk,which seriously affects the quality of the coiling,which causes the burning cone to fall easily in the process of smoking sucking,that is,the phenomenon of "burning cone off" produced during the smoking process,which seriously affects the quality of the product and the image of the enterprise.The development and application of on-line blade wire length limiting equipment have undergone several stages,such as proposal,overall design,development of off-line wire limited length equipment prototype,design and implementation of on-line installation of wire limited length equipment,on-line on-line test operation of wire limited length equipment,overall test,optimization test of key process parameters of blade length limiting equipment and verifying effect of blade length.In the process of R & D,there are many groups of knives,that is,"moving knife" arranged in a certain rule,and speed regulation through frequency converter.When there is a relative speed difference between them,the tearing and tearing of tobacco can get the limit effect of tobacco.Through changing the relative speed difference and the gap of the knife,the effect of different tobacco length can be obtained.In the selection of the cutter type,in order to highlight the cutting edge of the knife and improve the cutting effect of the tobacco,the spheroid knife body is selected,the effect of the blade length is the best,the filament rate is greatly reduced and the rate of the middle silk is improved obviously.Through the optimization of the key process parameters,the best combination of parameters is 30 mm pitch and 450/150 speed(r/min).The application of this equipment is obvious in improving the structure of tobacco during the process of cigarette processing,and the structure of the tobacco is basically in the same level as the fixed length cut wire,and the quality of the cigarette is basically maintained at the same level.At the same time,because online can realize the fast conversion of limited length and unlimited length,the production efficiency and transformation cost are greatly improved.
