More specifically, the opening treatment comprises opening roller opening and spinneret plate opening, wherein the opening roller opening is a speed difference formed by enabling the acetate fiber tows to pass through two pairs of opening rollers which are opposite up and down, so that the acetate fiber tows form a traction acting force between the two pairs of opening rollers to achieve the opening purpose, and the spinneret plate opening is that after the acetate fiber tows opened by the opening roller are introduced into the spinneret plate, the compressed air on the spinneret plate is used for blowing away the acetate fiber tows to achieve the further opening purpose.
Specifically, the process of spraying 10-40% by mass of glycerol triacetate for cigarettes on the surface of the opened acetate fiber tows is completed in a glue spraying box, and the acetate fiber tows opened by a spinneret plate are introduced into the glue spraying box and the glycerol triacetate for cigarettes is applied to the surface of the acetate fiber tows.
Specifically, after being tensioned and stabilized by a stabilizing roller, acetate fiber tows with the surface provided with cigarette triacetin enter a steam pressing plate of a forming cigarette gun for molding under the guide of a yarn feeding shaft, and then enter a cooling pressing plate for cooling, solidifying and shaping to form the wrapping-free paper filter stick.
The invention has the beneficial effects that: the forming process of the filter rod without the wrapping paper is provided, so that the filter tip and a cigarette can be integrally formed when being connected, the problems that the appearance of the cigarette is greatly influenced and the burning and air leakage of the tobacco leaves are easily caused due to the fact that the tipping paper for the cigarette is usually thin and the forming paper for the filter rod is thick and the layering or folding phenomenon is easily caused between the tipping paper for the cigarette and the forming paper for the filter rod under the influence of an adhesive after being connected are solved, and the stability of indexes such as the suction resistance and the hardness of the filter rod without the wrapping paper is convenient to improve.
