Description

Technical Field

[0001] The utility model relates to the technical field of cigarettes, in particular to an improved structure of a Collins filter rod. Background Art

[0002] Grooves and ridges are distributed along the periphery of the filter element of the Collins filter rod, which is generally used as the base rod unit of a composite filter rod. Due to the existence of the grooves and ridges, it is difficult to ensure good roundness of the forming paper wrapped outside. The basis weight of the paper determines the hardness, and the hardness affects the processing difficulty of the forming paper and the roundness of the Collins filter rod after wrapping. When using forming paper with a higher basis weight, the paper is too hard, and process problems such as delamination and bursting are likely to occur. After using forming paper with a basis weight of 40-60 g for wrapping, although the problems of bursting and delamination are significantly improved, the hardness of the paper decreases, and it is difficult to ensure the roundness of the forming paper. In traditional Collins composite filter rods, due to the insufficient hardness of the paper, the shape of the ridges is not obvious after cigarette connection, and the forming paper at the grooves collapses, resulting in a non-round appearance of the end face of the filter rod. At the same time, during the composite process, due to external force extrusion and paper deformation of the forming paper, the shapes of individual ridges and grooves change, resulting in problems of poor appearance and roundness. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide an improved structure of a Collins filter rod to solve the problem of low roundness of traditional Collins filter rods.

[0004] The technical solution of the utility model is: an improved structure of a Collins filter rod, including a filter element and a forming paper layer. Grooves and ridges are provided on the outer peripheral surface of the filter element, and the forming paper layer is wrapped around the filter element in a cylindrical shape. The forming paper layer is composed of at least two spiral paper cylinders, and the spiral paper cylinders are formed by winding a paper tape in a spiral shape and are glued together between the spiral paper cylinders.

[0005] The technical effect of the utility model is: the forming paper layer wrapped outside is wound in a spiral shape by multiple paper tapes and bonded by glue, having a beautiful and straight external shape and extremely high roundness. The Collins filter rod made has a regular appearance and no collapse problem. The paper interfaces are in a spiral shape and overlap each other, and process problems such as delamination and bursting are not likely to occur. Brief Description of the Drawings

[0009] As shown in Figure 1 , 2 or 3, an improved structure of a Collins filter rod includes a filter element 1 and a forming paper layer 2. The outer peripheral surface of the filter element 1 is provided with grooves 3 and ridges 4, which are arranged at intervals and have a gear-like profile. The forming paper layer 2 is wrapped around the filter element 1 in a cylindrical shape. The forming paper layer 2 is composed of at least two spiral paper tubes 5, and the spiral paper tubes are formed by winding a paper tape in a spiral shape. The spiral paper tubes are glued together. The single-layer spiral paper tube can be made of paper with a basis weight of 20-30 g or higher. Compared with the traditional Collins filter rod, due to the existence of the glue layer and the spiral winding structure, for the forming paper layer with the same thickness, the structure of the multi-layer spiral paper tube has better stiffness and better roundness.

[0010] The spiral paper tube 5 has three layers. The stiffness of the three-layer spiral paper tube is better than that of the two-layer one, and more layers of paper tubes will increase the thickness of the forming paper layer.

[0011] The different spiral paper tubes 5 are made of paper tapes with different widths. The probability of the seams of different layers overlapping together can be reduced.

[0012] The paper tapes used for the different spiral paper tubes 5 gradually increase in width from the inner layer to the outer layer.

[0013] The widths of the paper tapes used for the different spiral paper tubes 5 differ by 0.5-1 mm in sequence.

[0014] A circular channel hole 6 running through both ends is provided at the axis of the filter element 1.

[0015] The paper tube can be formed by spirally winding three layers of paper. The three layers of paper determine that this type of Collins filter rod has extremely high hardness. At the same time, the three layers of paper can be arbitrarily matched. For example, two to three layers of them can be selected as the aroma-carrying forming paper, and the aroma-carrying amount is larger than that of the traditional aroma-carrying filter rod. This filter rod can also be used for the filter rod of a heat-not-burn cigarette. The forming paper can be arbitrarily selected from materials such as PLA material and aluminum foil paper, which are cooling materials according to requirements. Multiple functions are reflected in one filter rod. It has stronger functionality and processability.
