Abstract
The invention discloses a multi-concave arc-shaped hollow core composite filter rod and a composite filter tip. The multi-concave arc-shaped hollow core composite filter rod is formed by wrapping a hollow filter core with forming paper. The central position of a cross section of the hollow filter core is provided with a multi-concave arc-shaped hollow core, and a multi-concave arc shape refers to a polygon with side lines being all or partially arcs recessed inwards. The multi-concave arc shape is in a 3-concave, 4-concave, 5-concave, 6-concave or 8-concave arc shape. The multi-concave arc-shaped hollow core composite filter rod has excellent flexibility and rigidity, has variable touch and very good resilience after being kneaded by fingers; a unique hollow structure makes smoke gas perform circulation backflow in the filter rod, and the cigarette taste is improved.
Description
Technical field
The present invention relates to a kind of hollow composite filter and its composite filter tip.
Background technology
The hollow filter stick that tobacco business adopts, is made up of forming paper parcel hollow filter element.The hollow core portion one of hollow filter element
As be circular, polygon or multi-corner star-shape.
Number of patent application is that 2008201129132 patent is related to a kind of hollow cigarette filter.Described filter plug is sky
Cored structure, at described hollow core structures one end open to filter plug suction inlet.
The patent for 2013205063718 for the number of patent application provides a kind of special type hollow composite filter, including base rod, described
The tail end of base rod is also connected with special type hollow filter stick, and described special type hollow filter stick passes through to heat rapid shaping, no in process of production
Forming paper wraps up, and does not have strike-through phenomenon to occur；And the cross section of described special type hollow filter stick inner chamber is circular, star or polygon
Multiple pattern of different shapes such as shape.
The hollow core structures of above two filter stick are fairly simple, and finger force is difficult after being affectedly bashful to recover original circularity, or even
Cracking destruction original hollow outward appearance, impact suction sensory experience.
A kind of number of patent application process units of hollow profiled filter stick that has been 2011101356151 disclosure of the invention, is becoming
Keep at a certain distance away between type machine and opener, this segment distance is installed a steam curing system, steam curing system includes
One group of high pressure air jet nozzles, molding tongue, for clamping the strap mechanism that tow band is moved along, opium pipe passage, steam generator；
Strap mechanism is connected with host driven installation, and high pressure air jet nozzles are connected with opener, for receiving what opener conveying came
Silk ribbon, the outfan of high pressure air jet nozzles are communicated with molding tongue, tow band are re-fed in molding tongue, the front end of molding tongue is fixed
There is strip hollow mould.The mold feature of this invention gives to present invention offers certain technology enlightenment.
Content of the invention
Goal of the invention:
A kind of pliability, resilience is provided to have concurrently, many arcs of recessess hollow composite filter of good looking appearance and composite filter tip.
Technical scheme:
Many arcs of recessess hollow composite filter disclosed by the invention, is made up of forming paper parcel hollow filter element, described hollow filter element
Cross-section center position there is many arcs of recessess hollow, described many arcs of recessess refer to that a kind of sideline is all or part of and concave
The polygon of sunken camber line.Described sideline be etc. arc length, etc. radian sunken inside camber line, sunken inside camber line can bring good
Feel is flexible and resilience (due to the presence of indent camber line, finger be affectedly bashful filter stick dynamics larger when, filter stick caves inward；Finger
When being affectedly bashful the dynamics of filter stick and reducing, filter element resilience restores to the original state, and filter stick outward appearance is full indeformable, keeps original deflection).Will be interior
Sunken radian is defined as θ, and the span of θ is 20 ° -60 °；Described sideline is preferably 3,4,5,6 or 8, and that is, many arcs of recessess are
3rd, 4,5,6 or 8 concave-curve.
The diameter of section of this filter stick is defined as d, the circumscribed circle diameter of concave-curve hollow is defined as d1, concave-curve is empty
The inscribed circle diameter of core is defined as d2, and the span of d is 5-7.8mm.Preferably d1=(1/4-3/4) d, -45 ° of θ=30 °.
Preferably d2=(2/3-9/10) d1, filter element had both had enough elasticity, will not cause sunken inside camber line to centre bit again
Put excessive collapse to block up, it is to avoid produce expendable hollow tube wall collapse-deformation.
When the area of hollow is larger, filter element feel is lighter, soft, saves the usage amount of filter element raw material；Hollow
Area less when, filter element feel is more abundant, than more flexible.
The primary raw material of described hollow filter element be acetate silk and triacetyl glycerine (triacetyl glycerine with account for
The weight of acetate silk ratio is for 15-25%), draw through the mechanical and custom-designed core of pultrusion and heating pressing technology
Pull into type, form bulk density and be about 0.2-0.4g/cm3, filter element between 0.02-0.06mpa for the tensile strength.Guarantee to filter
Rod has suitable toughness, deflection and circularity, attractive appearance, good mechanical properties.
The entrance face of the molding core that the present invention adopts is regular polygon, and exit end face is many arcs of recessess, entrance face
Shape to the core of exit end face is to gradually change excessive so that filter element raw material enters molding machine barrel and core composition
Gradually inwardly extended flexural deformation after die cavity, the preferably area of exit end face are not less than the area of entrance face so that filter element quilt
The pressure of extruding obtains certain release, and the permeability of flue gas is more preferable；And coordinate the change of machine barrel and die temperature so that bonding
Agent (triacetyl glycerine) gradually solidifies, and is finalized during filter element drawing outlet mold.
The present invention adopts suitable material to combine special many arcs of recessess hollow filter element, when being contained in suction in cigarette, staff
Refer to is affectedly bashful action so that there is the change of convolution in path when flue gas passes through from filter element, increased extra filtration differential effect with
Overall good filter capacity.
The filter stick of the present invention cuts into the filter section of arcs of recesses hollow more than many vertically, takes a concave-curve hollow filter Duan Yuqi
The filter stick segment end face docking of its type, periphery makes composite filter by forming paper parcel.When being mounted connected in cigarette, other classes
The filter stick segment of type is contacted with cigarette, and concave-curve hollow filter section is contacted with the oral area of smoker.
Beneficial effect:
The filter stick novel appearance of the present invention is unique, is changed by geometry etc., can strengthen filter stick visual impact and false proof work(
Can, improving product is worth and brand image.Flue gas had certain delay, the flue gas meeting of delay before entering oral cavity in the cavities
There is part to deposit, some is dispersed in the air, smoking property of cigarette harm can be reduced.
Meanwhile, flue gas can be gathered concentration by hollow space, realize circulating reflux, can be lifted to a certain extent in mouth rod
Flue gas intensity, improves Medicated cigarette jealous.The present invention has good outward appearance and identification, has excellent pliability with just simultaneously
Property, there is after finger is affectedly bashful transformable feel and good resilience.Arcs of recesses hollow filter stick is easy to produce in batches, outward appearance
Quality is easy to precise control.
