Abstract
The present invention provides a cigarette tongue, and the working surface of a semiconical groove of the cigarette tongue of a cigarette making machine is coated and sandblasted. The roughness of the sandblasted coating ranges from third class to fourth class, the thickness is less than 1mm, and the hardness ranges from 800 to 1300HV. The material of the coating can be one of or the combination of charring silicon, charring titanium, charring wolfram, charring boron, titanium oxide, vanadium oxide, titanium boride, vanadium boride, silicon nitride, vanadium nitride and Sialon composite ceramics. When the coated cigarette tongue causes tobacco rods to quickly pass through the cigarette tongue to be compressed for the first time, the contact form of the tobacco rods and the surface of the semiconical groove is changed from surface contact into point contact, the friction force of the tobacco rods passing through the cigarette tongue is greatly reduced, tight end displacement due to the blocked tobacco rods is avoided, and thereby, the bear rate of the cigarette making machine is obviously reduced. When the coated cigarette tongue is worn after used for a long time, the coated cigarette tongue can be coated once again, so the cigarette tongue of the cigarette making machine can be repeatedly used, and the service life of the coated cigarette tongue and the service life of an inward cigarette tongue have no obvious difference.
Description
Technical field
The present invention relates to cigarette machine, particularly a kind of cigarette machine cigarette tongue.
Background technology
The cigarette tongue is that cigarette machine rolls and gives the vital part that tobacco rod compresses for the first time in the formation system, the working face of cigarette tongue is the semicircle conical surface groove that shrinks gradually, first section groove combination of it and opium pipe base plate forms first section that rolls shaping---the circular cone passage that shrinks gradually.
According to the cigarette machine structural principle, plume forms the close end position of plume after the smoother finishing, makes the two ends formation of light mouth cigarette be about 8mm, and tobacco density increases the close end of 8-12%, guarantees that cigarette props up the rubbing quality of the full of firing tip and yew paper.Plume after the smoother finishing is entered the rod forming system by the compression of cigarette tongue behind scraper---the circular cone passage that shrinks gradually.Plume is by in the cigarette tongue compression process, plume with the linear speed of 448m/min from the about 69mm of sectional area
2Be compressed to 33mm
2Pipe tobacco is subjected to violent friction herein, particularly the close end of plume place is because of the high suffered frictional resistance maximum of tobacco density, thus the pipe tobacco at the close end of plume place more easily produce backward offset phenomena cause plume cut into cigarette when propping up cutting position form nominal cigarette not at close end place.Bear's cigarette is the main waste product in all kinds of in process of production waste products of cigarette unit, and the quantity that nominal cigarette props up accounts for about 80% of waste product total amount.Therefore, reduce nominal cigarette number and have remarkable economical value.Thereby how reducing the displacement that frictional force that pipe tobacco is subjected in cigarette tongue place reduces the close end position of plume effectively is the target of those skilled in the art's long-term endeavour.
The Protos70 that the model that the present inventor makes at German Hauni company provides for Protos70 and Protos100 cigarette unit cigarette tongue and Shanghai new city tobacco machine factory (piece number: 38DS324F104) and Protos100 (piece number: cigarette tongue 38DS477F1.101) is discovered, when cigarette machine is changed new cigarette tongue, because there is oxide layer on cigarette tongue surface, fineness is higher, and is relative with the frictional force between pipe tobacco less; But when tobacco rod compressed for the first time by cigarette tonguing row at a high speed, tobacco rod was whole with cigarette tongue semicircle conical surface groove and contacts, owing to certain friction effect makes the tobacco rod close end movement that is obstructed produce cigarette and prop up the empty pine of head.And in use for some time, because the erosion of the rapid wear of cigarette tongue surface oxide layer and the liquid phase substance that is subjected to ooze out after the pipe tobacco extruding, cigarette tongue surface becomes comparatively coarse, and the frictional force between pipe tobacco increases, thereby make the close end of plume produce displacement, cause the higher phenomenon of cigarette bear's rate.
How to make cigarette tongue surface smoothness keep perfect condition in the long period, the erosion of the liquid phase substance that oozes out after not pushed by pipe tobacco, make pipe tobacco remain on relative less state with frictional force between the cigarette tongue, thereby cigarette bear rate is remained on relatively low state, be technical problem underlying to be solved by this invention.
Summary of the invention
The object of the present invention is to provide a kind of cigarette tongue, reach and reduce the quantity that cigarette machine props up at manufacture process hollow head cigarette, the reduction cigarette machine rolls vital part---the cost of use of cigarette tongue in the formation system.
For reaching above-mentioned purpose, the present invention realizes by the following technical solutions,
A kind of cigarette tongue adopts coating technology to carry out coating on the working face of the half-conical groove of cigarette machine cigarette tongue and sandblasts.
