Description
Technical field
The present invention relates to a kind of low quantitative Time of Fluff Slurry dry-press process technology and device that the static wadding gathers of removing; Be specially on the needle leaved wood napped pulp fibres moulded head of dry type tobacco sheets by paper making method production equipment; Low quantitative moulding and elimination static wadding gather the technology and the device of phenomenon, belong to the reconstituted tobacoo production technical field of cigarette industry.
Background technology
Reconstituted tobacco (claiming reconstituted tobacoo again) is as the inserts of cigarette product; It is the important component part of cigarette composition; It can replace tobacco leaf to use on the one hand; Save raw tobacco material, effectively reduce the service efficiency of natural tobacco leaf ingredient in the cigarette, raising tobacco leaf resource, help the raising of cigarette interior quality.
Dry type paper-making method recreated tobacco is with the extraction of raw materials such as crumbled tobacco, offal, tobacco powder process, isolates insoluble matters such as extract and collection slag, operations such as collection slag economy-combat loose powder is broken, screening, oven dry; Process the substrate raw material; On dry method of paper-making machine, utilize the air bells laid method again, in conjunction with adding needle leaved wood napped pulp fibres and other effective ingredient substrate of manufacturing paper with pulp out; The raw materials such as medicinal extract of reason extract modulation are gone back in coating on substrate then, and dry, branch cuts into the reconstituted tobacoo finished product.Manufacturing paper with pulp of substrate is different because of the adding method of raw material with forming process; Known have layer-stepping to add and two types of hybrid interpolations; The layer-stepping adding method be at first on forming net air bells laid go out Time of Fluff Slurry bottom (claim again load hold layer); On this bottom, successively add raw materials such as collection slag, adhesive, top layer again and process substrate, like patent of invention " reconstituted tobacoo and manufacturing approach thereof and the manufacturing system " (application number: 00808488.2 applying date: 2000.06.02) described method of Japan tobacco Inc in China's application; Hybrid interpolation is after earlier raw materials such as fluff pulp fibers and the slag that comes together fully being mixed; Send into into the moulding of net type overdraught in the lump; Like Chinese invention patent " a kind of dry type paper-making method recreated tobacco and production method thereof " (application number: 200810030146.5 applyings date: 2008.08.08) disclosed method; The weak point of this method is: granular collection slag starch and fluff pulp fibers weight and physical form difference between the two is bigger; How the form difference that in the moulding air-flow, manifests is big, the problem such as that occurs on the moulding wire side in the actual forming process that the collection slag is inhomogeneous with the distributed pole of outer fiber, collection slag starch runs off.
The key of layer-stepping adding method is the fluff pulp fibers bottom forming technique of (claim again to carry on a shoulder pole and hold layer); Because the Time of Fluff Slurry that dry method of paper-making industry is used is the fiber of length >=2mm; After the moulding paper product quantitatively >=45g/ ㎡; The chemical fibre length that the adhesive-bonded fabric industry is used even＞6mm, its forming net selects for use 40～60 purpose polyester webs to get final product.Because reconstituted tobacco requires to add fluff pulp fibers can only be in 15～30g/ ㎡ scope; If the simple bottom moulding aspect that the forming technique and the device of dry method of paper-making employing are referred to reconstituted tobacco; Then can produce following problem: 1. bottom difficult forming; Particularly Fiber Distribution does not reach index request, and fiber loss is many in the process of manufacturing paper with pulp, and is quantitatively restive; 2. fluff pulp fibers is in air-flow sedimentation forming process, because of reasons such as frictional static, polyester webs induction static, makes on the wire side that the Fiber Distribution of moulding is extremely inhomogeneous, wadding gathers seriously, and quantitatively low more, problem is outstanding more, or even can't moulding; 3. the control of adopting sprinkling antistatic additive elimination electrostatic methods to be inappropriate for reconstituted tobacco again adds the raw material standard requirement; 4. the fluff pulp fibers bottom after the moulding shifts from forming net and peels off difficulty, and it is big to wash the net difficulty, has influenced the service life of forming net.
China's utility model patent " a kind of compound dry method paper machine " (application number: 01252096.9 applying date: 2001-10-10) disclosed gummed, heat seal or compound dust-free paper production line, patent of invention " a kind of manufacturing approach of the dust-free paper " (application number: 200710038476.4 applyings date: produced 2007-03-26) with " a kind of former that is used for dust-free paper production line " (application number: 200810198433.7 applyings date: 2008-09-08) in the disclosed content, do not relate to the scheme content of solution with the problems referred to above.
