The production method for the groove formed paper for the cigarette filter tips sequentially comprises the following steps of: (1) preparing a material: cellulose diacetate; (2) loosening and sizing; (3) pressing to form sheets in a sheet pressing alignment roller (11); (4) pressing to form groove-shaped sheets in a groove pressing alignment roller (12); and (5) recoiling and packing a groove formed paper tape product. The cellulose diacetate is prepared into the groove-shaped formed paper by adopting a method of pressing and heating, the method is simple and feasible, the increased equipment is simple, and the rest equipment is the production equipment in the prior art, so the production cost is not improved, most operation methods in the prior art are not changed, and field workers and masters can quickly learn and operate the production line.
Description
Technical field
The invention belongs to cigarette filter tip rod auxiliary material production technical field; Specifically cellulose diacetate is produced through processes such as compressing tablet, indents; A kind ofly can significantly reduce the cigarette harmful smoke, have the production method and the equipment of the forming paper of remarkable groove structure simultaneously.
Background technology
In the prior art, produce that a kind of consumer can accept, the cigarette that has low harmfulness again simultaneously, desirable solution is exactly, keeps that simultaneously and partly lets and consume all that the person produces the satisfied composition of suction selecting to remove hazardous compound.Simultaneously because mostly the Chinese style cigarette is the characteristics of Virginian-type cigarette; How to guarantee flue gas and inhale flavor; Also be one of filter tip emphasis of design tackling key problem difficult point, the groove filter tip is because it good falls burnt performance and appearance property is that one of more function filter product is selected in present state inner wrap strip market for use.Problems such as at present on the domestic market, it is forming paper that homemade groove filter tip forming paper product all adopts the body paper grooving, and quality does not reach a standard as yet so far, and all more or less appearance groove position is disorderly in the product, outward appearance is unintelligible also have influence on and fall burnt effect.The groove forming paper quality of external import is better, but price office is high not down, and domestic cigarette enterprise can't be adopted in a large number.
Summary of the invention
Above-mentioned deficiency to prior art; The technical problem that the present invention will solve provides the production method of a kind of cigarette filter tip rod with the groove forming paper; Adopt the most frequently used material cellulose diacetate of filter rod successfully to make to fall burnt effective, presentation quality might as well the groove forming paper.This method specialized apparatus also is provided simultaneously.
Technical scheme of the present invention is: cigarette filter tip rod is with the production method of groove forming paper, it is characterized in that described production method undertaken by following steps in order:
(1) get the raw materials ready: the raw material of making the groove forming paper is the strand material cellulose diacetate of using always;
(2) cellulose diacetate is carried out shredding, gluing;
(3) cellulose diacetate of shredding, gluing to be sent into pressure through centralised arrangement (10) be 1.5～1.8 crust, and temperature is 130 ± 30 ℃, and surface be in the compressing tablet pair roller (11) on plane, suppresses in blocks;
To import pressure be 1.2～1.5 crust to the cellulose diacetate in blocks of suppressing of (4) discharging from compressing tablet pair roller (11), and temperature is 100 ± 30 ℃, and the surface is provided with in the indent pair roller (12) of asperities, is pressed into the channel form sheet;
(5) will be pressed into the groove forming paper carries product rewinding packing of channel form sheet through guide roller (13), rewinding unit (14).
Described shredding, go up in the glue process, the speed controlling of shredding unit 30-70 rice/minute, the stent of cellulose diacetate after shredding is at 80-150mm.Described shredding, go up in the glue process, through the adjustment opening roller left side roller of speed ratio regulating handle: the right roller of opening roller: the speed ratio of conveying roller is 1: 1.3: 1.5.In described compressing tablet pair roller and the indent pair roller, be provided with 4 electric heating tubes in each roller inner chamber, electric heating tube connects carbon brush through electric wire and conducts heating.Asperities described in the indent pair roller of described asperities is the raised grain of sharp comer.Described raised grain is straight raised grain, or the oblique wave Slippage, or the shear wave Slippage.
A kind of production equipment special of producing above-mentioned cigarette filter tip rod with the groove forming paper; Contain shredding gluing unit; Rewinding unit; Its special feature is: this equipment also contains special-purpose indent unit, and the indent unit mainly is made up of centralised arrangement, compressing tablet pair roller, indent pair roller and corresponding heating arrangements and controlling organization; Wherein, the compressing tablet pair roller is a straight roll, and the surface of indent pair roller is provided with the raised grain of ups and downs sharp comer; Four electric heating tubes are set in each roller of compressing tablet pair roller and indent pair roller, and electric heating tube connects carbon brush through electric wire; The compressing tablet pair roller also links to each other with increment of rotation formula encoder with the indent pair roller, and increment of rotation formula encoder links to each other with temperature controller on the control panel.Described raised grain is straight raised grain, or the oblique wave Slippage, or the shear wave Slippage.
Advantage of the present invention is: at first; Production method of the present invention has been selected for use a kind of people to practise sky to see the material of being used to; It is the raw material that common strand material diacetate fiber is usually made the groove forming paper; Break through people's set thinking, produced and the import groove forming paper high quality of products of U.S.A mutually, solved present situation under one's control.The present invention adopts the method for heating cellulose diacetate to be pressed into the forming paper of groove shape; Method is simple; The equipment that increases is also very simple, and remaining all uses the production equipment of prior art, does not improve production cost; Do not change most of methods of operating of prior art, make the field worker master worker can learn and operate this production line very soon.
