Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette manufacturing, and in particular relates to a filter rod or cigarette cutting device. Background Art

[0002] During the production of filter rods, the fully loosened and plasticized tow belt is transported to the molding system, wrapped with molding paper coated with lap glue and center glue at the entrance of the pipe, and enters the small pressing plate, large pressing plate, pipe with the cloth belt to be rolled into filter strips that meet the process requirements, and finally cut into filter rods of equal length. The overlapping bonding of the filter rod, the center glue bonding, the loosening of the tow, the spraying of plasticizers and the curing of the filter rod will have a great impact on the product quality of the filter rod. For example, poor overlapping bonding of the filter rod will cause the filter rod to burst and the emission pipe to be blocked; poor center glue bonding of the filter rod during cigarette rolling will cause the solidified tow tissue to slide, produce unqualified cigarettes, and even cause the rolling machine to fail to work properly; poor loosening of the tow and poor plasticizer spraying will cause the filter rod to have large suction resistance and weight fluctuations, affecting the taste and flavor of the cigarette.

[0003] Therefore, the filter rod overlap, center line adhesive bonding, tow opening, plasticizer spraying, and filter rod curing are the process indicators that need to be checked in the filter rod production, and special inspections need to be carried out regularly. When checking such process indicators, it is usually necessary to cut open the filter rod forming paper and remove the complete forming paper belt or tow organization for further inspection, analysis and research. Similarly, in the production of cigarettes, the overlap of cigarettes and tobacco filling will have a great impact on the product quality of cigarettes, and it is also necessary to regularly cut open the tipping paper for inspection, research and analysis.

[0004] At present, when checking process indicators such as filter rods or cigarettes, the forming paper or tipping paper is usually cut by hand or with a blade. This method has the problems of inconvenient operation, difficult to control the cutting force, irregular incision, easy damage to the fiber bundle structure and the filling state of the tobacco, resulting in inaccurate inspection, analysis and judgment.

[0005] In the related art, a filter rod cutter consisting of a body and a blade has been developed. The body is provided with a slideway, which allows the filter rod to slide inside it, and the blade extends into the body and partially into the slideway, the blade edge is opposite to the direction in which the filter rod extends into the slideway, and the axis of the slideway is located in the plane where the blade is located. When the filter rod passes through the slideway, the filter rod forming paper is neatly cut by the blade along the axis of the filter rod.

[0006] The cutter of the cutter is a common cutter with an oblique cutting design. The tip of the cutter is used to cut the shaping paper. The cutting resistance is large, which can easily cause the shaping paper to tear or wrinkle, and it is easy to accumulate paper scraps, glue residue and other debris.

[0007] The cutter is designed with a single slide and can only cut filter rods with one circumference specification, which cannot meet diverse needs and has certain limitations;

[0008] The main body of the cutter is of integral design, that is, a small hole is opened on the main body to insert the cutter, the main body cannot be disassembled, the small hole is easy to be blocked, and it is difficult to clean the debris. Summary of the invention
