Summary of the invention
For defect existing for common cellulose acetate filter rod in the prior art, the purpose of the invention is to provide it is a kind of at
This low, less harmful has certain unique perfuming type cigarette filter rod of absorption retention functions and flavoring performance, appearance.
Another object of the present invention is to be to provide described in a kind of low, easy to operate, the inexpensive preparation of equipment requirement to add
The method of odor type cigarette filter rod.
Third object of the present invention is the application for being to provide a kind of perfuming type cigarette filter rod in cigarette, can be made
It is used for production of cigarettes for single rod, it can also be compound rear for production of cigarettes with conventional cigarette filter stick.
Existing perfuming type filter stick includes that the flavorings abilities such as quick-fried pearl filter stick, flavoring particle stick, flavoring line are limited, and without departing from
This main body of vinegar fibre filter stick, molding equipment, raw material and processing cost are high, and vinegar fibre is difficult to degrade to cause Heavy environmental pollution.
To overcome the problems, such as existing cigarette filter rod, the present invention provides a kind of preparations of cigarette filter rod with flavoring function
Edible essence material, is mixed to assign fragrant plant granule by method with the particle of natural plant material, and the tax perfume (or spice) plant granule is applied
Add and prepares plant granule pole through tobacco particle pole molding machine after adhesive;
The tobacco particle pole molding machine includes single screw rod extrusion system and cooling and shaping system;
The single screw rod extrusion system includes feeder and squeezer;The feeder is arranged on squeezer;It is described to squeeze
Depressor includes machine barrel, and heater is equipped with outside the machine barrel, and inside is equipped with screw rod, and machine barrel one end is equipped with mouth mold;
The cooling and shaping system includes round tube and cooler;The cooler is arranged in circular tube external;The round tube one
It is docked with the mouth mold of squeezer at end;The multiple groups groove parallel with screw axis is provided in the head threads of the screw rod;
The mixed material is entered in the machine barrel of squeezer by feeder continuous charging, under screw extruding effect, from
Die extrusion enters in the round tube of cooling and shaping system, after carrying out cooling and shaping, squeezes out, and obtains the plant granule pole (present invention
Also referred to as tobacco particle pole, the fragrant natural plants particle pole of tax, also referred to as pole);
The plant granule pole is cut directly into type, or using excision forming after forming paper package to get described
Cigarette filter rod.
Technical solution of the present invention can be realized by designing a kind of special cigarette filter tip shaping device by natural baccy
The particle one-step shaping preparation cigarette filter rod with benefit Xiang Gong energy, and continuous production may be implemented, it enormously simplifies
The preparation process of existing cigarette filter rod, and the equipment utilized is simple, cost is relatively low, is advantageously implemented industrialized production.
Technical solution of the present invention, filter stick are glued by assigning fragrant natural plant material by one step of specially-shaped device
Synthesis type forms, and in edible essence material and natural plant material, safety more ensures the filter stick raw material sources of use;Material
Material can be degenerated after not only there is preferable degradation property, filter stick to abandon for organic fertilizer back feeding the Nature, have the better feature of environmental protection
Energy;No matter structure or appearance have basic sex differernce to filter stick with existing cigarette filter rod, and flavoring ability is prominent, can be used as existing volume
The perfect substitute of cigarette filter.
