Description

A filter rod filled with tow at triangular intervals and its processing method

technical field

The invention belongs to the technical field of tobacco, and in particular relates to a filter rod filled with triangular intervals and a processing method thereof.

Background technique

With the intensification of market competition in the tobacco industry, it is difficult for single-function cigarette materials to meet the needs of cigarette brand development and product specialization. With the application of new technologies, new processes and new materials in cigarette products, cigarette materials have developed from a single function to a multi-functional and diversified direction. Filter rods are an important part of cigarettes. With the increasingly fierce competition in the cigarette market, cigarette products with novel appearance and special functions are favored by consumers. Due to their special functions, hollow filter rods are used more and more in cigarettes.

The role of cigarette flavoring is to improve the physical and chemical properties of cigarettes, so that consumers can obtain specific taste, smell and touch, and improve the acceptability of cigarettes. There are also many ways to add flavoring, which are directly added to the cut tobacco, and some are added to other cigarette accessories such as filters, cigarette papers and packaging materials. In smoking products, microcapsules are placed at the joint between the filter tip and the cigarette, and can also be placed in the middle of the filter tip to become a filter tip, which plays a different role during smoking, while the flavoring substances maintain the original flavor, while at the same time. It can effectively set off the aroma of cigarette products, cover up miscellaneous air, and improve the taste.

The inner filter fiber filaments of the hollow filter rod disclosed in patent CN210076559U need to be thermoplastically formed, and need to be provided with several decompression channels (unfilled tows); Filling tow); Patent CN105342005A requires cellulose paper provided with multiple grooves. The hollow filter rod of the above-mentioned patent obviously has a complicated folded shape design of the forming paper, which is difficult to industrialize production, especially difficult to form at one time.

The present invention has been proposed to solve the above-mentioned problems.

The second aspect of the present invention discloses the preparation method of the filter rod filled with tow at triangular intervals, which is characterized in that a filter rod one-time forming system is used;

The filter rod one-time molding system includes the following components: a molding horn C, an outer molding paper conveyor belt 3W, an inner molding paper conveyor belt 3N, an outer tow conveyor belt 42 and an inner tow conveyor belt 52; the molding horn C includes an outer molding horn The mouth 11 and the inner bell mouth 21, the inner horn mouth 21 is sleeved in the outer shaped horn mouth 11; the outer shaped horn mouth 11 is cylindrical with a gradually decreasing radius; the inner horn mouth 21 is two layers, The outer layer 211 is a cylindrical shape that gradually transitions from a circle to an equilateral triangle, and the inner layer 212 is a equilateral triangle with a larger area at one end and a triangular prism shape with a smaller equilateral triangle at the other end;

The forming method of the filter rods filled with tow at triangular intervals includes the following steps: the outer forming paper conveyor belt 3W transports the outer forming paper W to the inlet of the forming horn C and is baked by the outer forming paper baking device 31 and then enters the outer forming horn 11. The inside of the cylinder is formed into the shape of a cylinder WI, and after being glued by the outer lap glue device 33, it comes out from the outlet of the outer forming trumpet 11. At this time, the outer tow S1 transmitted from the outer tow conveyor belt 42 is sent into the At the same time, the inner molding paper conveyor 3N transports the inner molding paper N to the inlet of the molding horn C and is baked by the inner molding paper baking device 32, and then enters the outer layer 211 and the inner layer of the inner molding horn 21. Between 212 and 212, after it is gradually formed into a cylindrical shape of a regular triangle N1, it is glued by the inner lap glue device 33 and then comes out from the outlet of the inner molding horn 21; S2 is fed into the inner forming paper N; the cylindrical shape of the equilateral triangle N1 is sleeved with the cylinder WI coming out of the outlet of the outer forming trumpet 11, and the outer tow is filled between the outer forming paper W and the inner forming paper N S1, the inner forming paper N is filled with inner tow S2; the formed filter rod is glued by the gluing device 35, and then the three vertices of the triangle N1 are glued to the inner wall surface of the cylinder W1, and then heated again. After the heater 36 is heated, it is cooled by the cooler 37 to form, cut by the cutter 38 and then output by the rod separation roller 39, that is, the filter rod with the triangular interval filled tow is obtained.

The prepared filter rod filled with tow at triangular intervals is used as the base rod A, and it can be prepared by compounding it with different types of filter rods B such as other explosive bead filter rods, particle filter rods, flavored filter rods, etc. in a certain order and length ratio. Triangular spaced tow binary composite filter rod; base rod A and filter rods B1 and B2 are compounded twice in a certain order and length ratio to make triangular spaced tow ternary composite filter rod.
