Problems solved by technology
Since the tip paper is usually thin and the filter plug wrapping paper is thick, delamination or wrinkling tends to occur between the tip tip paper and the plug wrapping paper due to the influence of the adhesive after splicing, resulting in the appearance of cigarettes. It is greatly affected, and it is prone to leakage of tobacco leaf combustion, so it has very high requirements for tipping technology and equipment precision

The invention discloses a formation technology of a non-wrapping paper filter rod and belongs to the technical field of formation of filter rods for cigarettes. The method comprises the steps that (a)a cellulose acetate fiber strand is subjected to opening by an opening roller of a filter rod formation machine and is in a fluffy state; (b) by mass, the surface of the cellulose acetate fiber strand after opening is sprayed with 10-40% of glyceryl triacetate for cigarettes; (c) the cellulose acetate fiber strand sprayed with glyceryl triacetate for cigarettes is introduced into a formation cigarettes pipe for shaping, steam with the temperature of 100-300 DEG C and pressure of 0.1-3 MPa is introduced for catalyzing a dissolution reaction of glyceryl triacetate and the cellulose acetate fiber strand through a steam press plate of the formation cigarettes pip; (d) the strand after the dissolution reaction is introduced to a cooling press plate, compressed air with the temperature of 0-30DEG C is introduced, and the strand is cooled, cured and formed into the non-wrapping paper filter rod. A filter tip and the cigarette can be integrally formed when the filter tip and the cigarette are connected, and the stability of indexes, such as suction resistance and rigidity, of the non-wrapping paper filter rod is conveniently improved.
Description
technical field [0001] The invention relates to a forming process of a filter rod, in particular to a forming process of a cigarette filter rod without wrapping paper, and belongs to the technical field of forming a cigarette filter rod. Background technique [0002] Existing cigarette filters are wrapped with filter rod forming paper during molding, and then cut into filter rod sections according to the required length. Packed into cigarettes with filters. Since the tip paper is usually thin and the filter plug wrapping paper is thick, delamination or wrinkling tends to occur between the tip tip paper and the plug wrapping paper due to the influence of the adhesive after splicing, resulting in the appearance of cigarettes. It is greatly affected, and it is prone to leakage of tobacco leaf combustion, so it has very high requirements for tipping technology and equipment precision. [0003] For this reason, the present invention develops a kind of forming process of filter ...
