Abstract
The utility model provides a carbon fiber coaxial filter rod. The carbon fiber coaxial filter rod comprises an inner filter element, an outer filter element and forming paper, wherein the diameter of the inner filter or the diameter of the circumscribed circle of the inner filter is 2mm to 6mm. Material of the inner filter element is activated carbon fiber, and the outer filter element is a cellulose acetate filter element or a paper element; and alternatively, the inner filter element is the cellulose acetate filter element or the paper element, and material of the outer filter is the activated carbon fiber. The periphery of the inner filter element can be wrapped with a layer of inner ring forming paper. The carbon fiber coaxial filter rod and other varieties of filter rods are cut into small filter sections, and the small filter sections are connected together in split mode and are jointly wrapped with one layer of forming paper to form a composite cigarette filter. The activated carbon fiber utilized by the carbon fiber coaxial filter rod is good in adsorption performance and strong in smoke filtration ability, a suction taste of a cigarette can be improved, and harm to the health of smokers is small.
Description
Technical field
The utility model relates to filter stick and the cigarette filter tip of cigarette, refers in particular to a kind of coaxial filter stick of carbon fiber filter core and cigarette filter tip of making thereof of containing.
Background technology
The filter tip of cigarette is to be cut by filter stick to form, and filter stick is to be formed by filter core and forming paper structure.Common filter core is to be made by independent acetate fiber core or refill, exists that structure is too simple, the not high enough problem of adsorptivity.
The number of applying for a patent discloses a kind of cigaratte filter and preparation method thereof for the specification of CN200610010602.0, consisted of by acetate fiber center bar, the outer rod of acetate fiber and the peripheral forming paper of center bar, there is sorbing material on the surface of forming paper, the adsorptivity that the method improves is not brought by the acetate fiber filter core, but provided by very thin forming paper, the absorption property of filter core itself is not improved, and the absorption property of filter stick integral body also just improves few.
The number of applying for a patent is that 201010592440.2 specification discloses a kind of " filter rod with coaxial paper cores ", contains filter core and outer ring forming paper.Filter core contains coaxial inner core and outer core, and inner core diameter is 3mm-6mm.Also can there be an inner ring forming paper inner core periphery.Inner core is refill, and outer core is the acetate fiber core; Perhaps inner core is the acetate fiber core, and outer core is refill.The primary raw material of refill is wood pulp cellulose.This filter stick absorption property is better, and refill is easy to degraded.But the filter core of the filter stick of this invention is compared with sorbing materials such as activated carbon fibers, and is still inadequate to the absorption property of flue gas gaseous substance.
Summary of the invention
The utility model purpose: overcome common filter stick and the inadequate defective of other coaxial filter stick adsorptivities, provide a kind of adsorptivity better, more healthy carbon fiber coaxial core filter stick.
Technical scheme: carbon fiber coaxial core filter stick of the present utility model, contain identical axle center internal layer filter core, the outer filter core of (referring to that here axial line overlaps or substantially overlaps), and the outer ring forming paper, the diameter of internal layer filter core or its circumscribed circle diameter are 2mm-6mm.The material of internal layer filter core is activated carbon fiber, and outer filter core is acetate fiber filter core, refill or other kind filter cores; Perhaps the internal layer filter core is acetate fiber filter core, refill or other kind filter cores, and the material of outer filter core is activated carbon fiber.
The periphery of described internal layer filter core can be enclosed with one deck inner ring forming paper, and inner core will wrap up closelyr, is convenient to filter stick production moulding, and the filter stick outward appearance after the moulding is better.
The shape of cross section of internal layer filter core can be circular, oval, polygon or irregularly shaped.
One deck groove fiber element paper can also be arranged between described outer filter core and the outer ring forming paper, further improve structure and the quality of filter stick.
The inner surface of described inner ring forming paper or outer surface can be coated with one or several white glue with vinyl or hot melt tree lace (glue is painted linear), to improve the adhesion of internal layer filter core and outer filter core.
The second goal of the invention: the cigarette filter tip that provides aforesaid carbon fiber coaxial core filter stick to make.
The second technical scheme: cut by described carbon fiber coaxial core filter stick and to form the little filter of carbon fiber core section, cut by the filter stick of other kinds and form other little filter section.
After the end face docking by the little filter section of carbon fiber core and other little filter section, jointly wrap up again the cigarette filter tip that one deck filter tip forming paper forms composite construction in the periphery.Wherein, the little filter section of carbon fiber core or other little filter section respectively have one section, two sections or several sections.
When the cigarette filter tip of described composite construction connected into filter tip cigarette, the little filter section of carbon fiber core, be unlikely to simultaneously in the absorbing carbon fiber entrance, and the outward appearance of cigarette filter tip did not have heterochromatic with the harmful components in the quick adsorption flue gas away from the lips and teeth end, near the pipe tobacco end.
Beneficial effect: inner core of the present utility model and outer core dual structure, wherein a kind of is the carbon fiber of high adsorption activity, can adsorb the pernicious gas such as tar, carbon monoxide in the flue gas, and absorption and filtration flue gas efficient are fabulous, can reduce the harm to health of smokers, improve the flue gas mouthfeel and inhale flavor.And, simultaneously, the coaxial filter stick of twin-core, the visual effect Unique of its end can increase aesthetic feeling and antifalse effect.Adopt cigarette filter tip of the present utility model, can improve suction mouthfeel and the class of cigarette, price can promote, and improves the economic benefit of cigar mill.
Description of drawings
Accompanying drawing 2 is perspective view of the cigarette filter tip made of the utility model;
Among the figure: 1, internal layer filter core; 2, inner ring forming paper; 3, outer filter core; 4, outer ring forming paper; 5, pipe tobacco end; 6, lips and teeth end; 7, the little filter section of carbon fiber core; 8, other little filter section; 9, filter tip forming paper; 10, groove fiber element paper.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is done more specifically description.
As shown in Figure 1, the end face of internal layer filter core 1 is that diameter is the circle of 3mm, and the material of internal layer filter core 1 is activated carbon fiber, and the periphery of internal layer filter core 1 is enclosed with inner ring forming paper 2.Outer filter core 3 is the acetate fiber core, and outer filter core 3 peripheries are enclosed with outer ring forming paper 4.The thickness of described inner ring forming paper 2 is not more than outer ring forming paper 4, and perhaps the transparency of inner ring forming paper 2 is not less than outer ring forming paper 4.
On a filter-stick forming device, make first the internal layer filter core 1 that is enclosed with inner ring forming paper 2, make again carbon fiber coaxial core filter stick at second filter-stick forming device.
In embodiment 1, the periphery of internal layer filter core 1 is not enclosed with inner ring forming paper 2.Outer filter core 3 peripheries are enclosed with first groove fiber element paper 10, again at its peripheral parcel outer ring forming paper 4.Make another kind of carbon fiber coaxial core filter stick at two forming machines again.
