Description
Technical field
The present invention relates to the former or molding die of a kind of filter stick for cigarettes.
Background technology
The patent of Application No. 201320506371.8 provides a kind of special-type hollow composite filter；Application No.
201320643679.7 patent, which provides a kind of inside, the cigarette filter stick of cavity.The filter stick of above-mentioned two patent is general
The filter stick of logical thickness, hollow or cavity filter core structure is also fairly simple, and function is relatively simple.
2013102061575 the invention discloses a kind of cigarette gun of filter rod former, it include noseplate, bottom plate and after
Bottom plate, is symmetrically installed with the elongate strip shaping channel that two pieces of center platens form straight line connection, in noseplate in bottom plate
Tubaeform feed inlet is equipped with above, and tubaeform discharge port is equipped with rear substrate, two in noseplate and bottom plate junction
Side is respectively equipped with the large plate corresponded and small pressing plate, faced in large plate and small pressing plate in front of bottom plate be equipped with one by
Gradually widened tapered channel groove, a semicircle reinforcement is equipped with the bottom surface of bottom plate along center line is corresponding with shaping channel
Groove.The present invention can effectively improve the quality of cigarette filter stick after above-mentioned improvement.
201120432394X the utility model provides a kind of hollow filter stick formation cigarette tongue of cigarette, contains sizing plug, core
The parts such as rod clamp, two plug adjusting screws, movable support, fixed screw, fixing bracket, oviducts.Plug of shaping is lived
Dynamic to be connected to Core rod clamp, fixing bracket is fixedly connected on oviduct, and movable support is connected to fixing bracket by fixed screw.Loudspeaker
Pipe shaft also has corresponding pipe shaft opening, and Core rod clamp passes through the pipe shaft opening, and plug adjusting screw can be perpendicular to sizing core
The direction of rod is freely adjusted, and is adjusted stroke and is more than 3.5mm, less than 10mm.Plug of shaping is in tapered elongated shape, its is transversal
Face can have circular, ellipse, heart-shaped, polygon or multi-corner star-shape；The circular arc internal diameter of oviduct outlet and the filter core diameter of filter stick
It is identical.The utility model appearance and size is tiny, and immanent structure is exquisite, and low cost, hollow filter stick formation is good, and sizing plug can
To replace, the hollow filter stick of a variety of hollow section shapes can be produced.
The content of the invention
Goal of the invention：
A kind of rapid forming mold of hollow filter stick is provided.
Technical solution：
The former of the hollow filter stick, for hollow filter core to be made by diacetate fiber, has shell mold and in shell mold
The core of center portion position, it is another that there is being connected with vapour source and unicom shell mold and the jet chimney with core inner cavity respectively.
The inner wall major part of shell mold is cylindrical shape, has length on its inner wall for 30-50cm and crowd is distributed with
The section of more shell steam vents；The outer wall major part of core is cylindrical shape, on its external wall with length for 15-35cm simultaneously
The section of numerous core steam vents is distributed with.
The distributed area of core steam vent is shorter in length than the distributed area length of shell steam vent, and the axial bore easy to hollow filter stick is use up
Fast sizing forms the mellow and full inner surface of smoother, is made not only beautiful but also smooth logical easy to flue gas during suction during cigarette filter
Cross.
Steam enters shell mold inside or the inside of core by respective jet chimney respectively.Shell steam vent and core steam vent
Moderate number so that the emitted dose of steam can meet triacetyl glycerine and the needs of diacetate fiber heating bonding in filter core,
Again insatiety and, avoid producing in condensed water and tow in die cavity and produce bubble, do not influence tow coagulation forming density and
Mechanical property.
Core can be made by covering ptfe plastic outside stainless steel tube, not only high temperature resistant but also reduce frictional resistance.
During production and application, the diacetate fiber for having sprayed triacetyl glycerine enters mould inside from tow inlet, is subject to
The extruding of mould is collapsed, and the outer wall of the inner wall from shell mold and core is ejected into tow vapor respectively so that three triacetins
Ester is uniformly merged with diacetate fiber, and promotees gradually coagulation forming, and last hollow filter core comes out from cartridge outlet.Water in filter core steams
Gas is gradually evaporated in follow-up process, becomes dry hollow filter core.
A diameter of 0.1-0.8mm of each shell steam vent, ejects, homogeneous heating in the form of steam rather than water are lived,
Water content is less in filter core；The size of core steam vent is not more than the size of shell steam vent.So that the quantity of steam sprayed in core is less than shell
Emitted dose in mould, the outer wall easy to moisture from filter core is evaporated, and drying effect is more preferable.
The head of core is preferably pointed shape, and the head of shell mold can have trumpet-shaped inlet, easy to the entrance of tow.
The afterbody of core and the afterbody of shell mold are preferably the cylindrical surface of standard, do not have vapour on the cylindrical surface near the afterbody
Hole, easy to the surfaces externally and internally of the formation smoother of hollow filter stick.
Beneficial effect：
The component of the former is simple, and mould inside structure design is exquisite.Shaping efficiency is high, and speed is fast.Manufactured sky
End face appearance, mechanical property and the strainability stability of heart filter stick are high, and rejection rate is low.

Embodiment
The mould of the former of hollow filter stick as described in Figure 1, has shell mold 3 and the core positioned at 3 centre of shell mold
Mould 8, it is another that there is being connected with vapour source and unicom shell mold 3 and the jet chimney 2 with 8 inner cavity of core respectively；The inner wall master of shell mold 3
Mian part is divided into cylindrical shape, has length on its inner wall for 40-50cm and the section of numerous shell steam vents 4 is distributed with；Core
The outer wall major part of mould 8 is cylindrical shape, and for 30-35cm and numerous core steam vents is distributed with length on its external wall
9 section.
The moderate number of shell steam vent 4 and core steam vent 9 so that the emitted dose of steam can meet triacetyl glycerine in filter core
With the needs of diacetate fiber heating bonding, and insatiety and.A diameter of 0.3-0.6mm of each shell steam vent 4, the ruler of core steam vent 9
The very little size no more than shell steam vent 4.The head of the core 8 of tow inlet 10 is pointed shape, the head of shell mold 3 it is horn-like enter
Mouthful.
