Description

Many arcs of recesses hollow composite filters and composite filter tip

Technical field

The utility model is related to a kind of hollow composite filter and its composite filter tip.

Background technology

The hollow filter stick that tobacco business is used, is made up of forming paper parcel hollow filter core.The hollow core portion one of hollow filter core As be circular, polygon or multi-corner star-shape.

Number of patent application is that 2008201129132 utility model is related to a kind of hollow cigarette filter.The filter tip It is hollow core structures, at the hollow core structures one end open to filter tip suction inlet.

Number of patent application provides a kind of special type hollow composite filter, including base rod for 2013205063718 utility model, The tail end of the base rod is also connected with special type hollow filter stick, and the special type hollow filter stick is fast rapid-result by heating in process of production Type, without forming paper parcel, does not have strike-through phenomenon；And the cross section of the special type hollow filter stick inner chamber is circular, star Or various patterns of different shapes such as polygon.

The hollow core structures of above two filter stick are fairly simple, and finger force is difficult to recover original circularity after being affectedly bashful, or even The original hollow outward appearance of cracking destruction, influence 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, into It is spaced apart between type machine and opener, a steam curing system is installed in this segment distance, steam curing system includes One group of high pressure air jet nozzles, shaping tongue, for clamping strap mechanism, opium pipe passage, steam generator that tow band is moved along； 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 output end of high pressure air jet nozzles are communicated with shaping tongue, and tow band is re-fed into shaping tongue, and the front end for being molded tongue is fixed There is strip hollow mould.The mold feature of the invention is given present invention offers certain technical inspiration.

The content of the invention

Utility model purpose：

There is provided a kind of pliability, resilience to have concurrently, many arcs of recesses hollow composite filters and composite filter tip of good appearance.

Technical scheme：

Many arcs of recesses hollow composite filters disclosed in the utility model, are made up of forming paper parcel hollow filter core, described The cross-section center position of hollow filter core has many arcs of recesses hollows, and described many arcs of recesses refer to a kind of sideline all or part It is the polygon of the camber line that caves inward.Described sideline be etc. arc length, etc. radian sunken inside camber line, sunken inside camber line being capable of band Carry out good feel flexibility and resilience（Due to the presence of indent camber line, finger be affectedly bashful filter stick dynamics it is larger when, filter stick concaves Fall into；When the dynamics that finger is affectedly bashful filter stick reduces, filter core resilience restores to the original state, and filter stick outward appearance is full indeformable, keeps original and endures Degree）.The radian that will cave in is defined as θ, and the span of θ is 20 ° -60 °；Described sideline is preferably 3,4,5,6 or 8, i.e., many Arcs of recesses is 3,4,5,6 or 8 concave-curves.

The diameter of section of the 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.It is preferred that D1=(1/4-3/4) D, -45 ° of θ=30 °.

It is preferred that D2=(2/3-9/10) D1, filter core both has enough elasticity, and sunken inside camber line will not be caused again to centre bit Put excessive collapse to block up, it is to avoid produce expendable hollow tube wall collapse-deformation.

Filter core feel is lighter, soft when the area of hollow is larger, saves the usage amount of filter core raw material；Hollow Area it is smaller when, filter core feel is more abundant, than more flexible.

The primary raw material of described hollow filter core is acetate silk and triacetyl glycerine（Triacetyl glycerine with account for The weight ratio of acetate silk is 15-25%）, drawn by pultrusion machinery and the core and heating pressing technology of special design Type is pulled into, bulk density is formed and is about 0.2-0.4g/cm³, filter core of the tensile strength between 0.02-0.06MPa.Ensure filter Rod has suitable toughness, deflection and circularity, attractive appearance, good mechanical properties.

The entrance face of the core that the utility model is used is regular polygon, and exit end face is many arcs of recesses, entrance face To the core of exit end face shape gradually change it is excessive so that filter core raw material enter what shaping machine barrel and core were constituted The area of gradually inwardly extended flexural deformation after die cavity, the preferably area of exit end face not less than entrance face so that filter core 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 solidify, be finalized during filter core drawing outlet mold.

The utility model combines special many arcs of recesses hollow filter cores using suitable material, when being aspirated in cigarette, Finger be affectedly bashful action cause flue gas from filter core by when path have the change of convolution, increased extra filtering difference and imitate Fruit and overall good filter capacity.

Filter stick of the present utility model cuts into the filter section of arcs of recesses hollow more than many, many arcs of recesses hollow composite filters vertically The many arcs of recesses hollows filter section for cutting into vertically is docked with other types of filter stick segment end face, and periphery is enclosed with forming paper can To be made composite filter.It is mounted connected to when in cigarette, other types of filter stick segment is contacted with cigarette, concave-curve hollow is filtered section and taken out The oral area contact of suction person.

Beneficial effect：

Filter stick novel appearance of the present utility model is unique, is changed by geometry etc., can strengthen filter stick visual impact And antiforge function, lift value of the product and brand image.Flue gas had certain delay in the cavities before oral cavity is entered, and was detained Flue gas have part deposition, some is dispersed into air, can reduce smoking property of cigarette harm.Meanwhile, hollow space can Flue gas is gathered into concentration, circulating reflux is realized in mouth rod, can to a certain extent lift flue gas intensity, improve cigarette jealous.

The utility model has good outward appearance and identification, while having excellent pliability and rigidity, is taken in finger There is transformable feel and good resilience after pinching.Arcs of recesses hollow filter stick is easy to batch production, and presentation quality is easy to essence Really control.

Specific embodiment

A kind of many arcs of recesses hollow composite filters as shown in Figure 2, wrap up hollow filter core 2 and constitute by forming paper 1, main former Expect to be acetate silk and triacetyl glycerine, triacetyl glycerine is 15-25% with the weight ratio for accounting for acetate silk； The cross-section center position of described hollow filter core 2 has many arcs of recesses hollows 3, and described many arcs of recesses refer to a kind of sideline 4 It is all or part of the polygon of the camber line that caves inward.Many arcs of recesses are 4 concave-curves.Described sideline 4 for etc. arc length, etc. radian Sunken inside camber line；Cave in radian θ span be 20 ° -60 °.

The diameter of section of filter stick is D, and the circumscribed circle diameter of concave-curve hollow is D1, and the span of D is 5-7.8mm, D1= (1/4-3/4)D；The inscribed circle diameter 6 of concave-curve hollow is D2, D2=(2/3-9/10) D1.

The core of a kind of many arcs of recesses hollow composite filters as shown in Figure 3, for producing many arcs of recesses sky shown in Fig. 2 Core composite filter.The entrance face 7 of core is square, and exit end face 8 is 4 arcs of recesses, entrance face 7 to exit end face 8 Core shape gradually change it is excessive.
