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 filter rod production, the fully loosened and plasticizer-sprayed tow belt is conveyed to the forming system. At the entrance tongue of the pipe, it is wrapped with forming paper coated with lap glue and center glue. It then enters the small pressing plate, large pressing plate, and pipe with the cloth belt to be rolled into filter strips that meet the process requirements. Finally, it is cut into filter rods of equal length. The overlapping and center glue bonding of the filter rod, the loosening of the tow, the spraying of plasticizers, and the curing of the filter rod will have a significant 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 splicing will cause the solidified tow tissue to slip, resulting in unqualified cigarettes and even causing the cigarette splicer to malfunction; poor loosening of the tow and poor plasticizer spraying will lead to large fluctuations in the filter rod's suction resistance and weight, affecting the taste and flavor of the cigarette.

[0003] Therefore, filter rod overlap, centerline gluing, tow opening, plasticizer spraying, and filter rod curing are key process indicators that require regular inspection during filter rod production, requiring specialized checks. Checking these process indicators typically requires cutting open the filter rod wrapper and removing the complete wrapper tape or tow for further inspection, analysis, and research. Similarly, in cigarette production, factors such as the overlap and tobacco filling significantly impact product quality, requiring regular inspection, research, and analysis by cutting open the tipping paper.

[0004] Currently, when inspecting process indicators such as filter rods or cigarettes, the plug wrap or tipping paper is typically cut by hand or with a razor blade. This method is inconvenient, difficult to control the cutting force, produces irregular cuts, and easily damages the tow structure and tobacco filling state, leading to inaccurate inspection, analysis, and judgment.

[0005] In related technology, a filter rod splitter has been developed, consisting of a body and a blade. The body has a slideway that allows the filter rod to slide within it. The blade extends into the body and partially into the slideway, with the blade's cutting edge facing the direction the filter rod enters the slideway. The axis of the slideway lies in the plane of the blade. As the filter rod passes through the slideway, the filter plug wrap is neatly split by the blade along the axis of the filter rod.

[0006] The cutter of this cutter is an ordinary cutter with an oblique cutting design. The tip of the cutter cuts the shaped paper, which has a large cutting resistance and is prone to causing the shaped paper to tear or wrinkle, and is prone to accumulating debris such as paper scraps and glue residue.

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

[0008] The main body of the cutter is of an integral design, that is, a small hole is opened on the main body for inserting the cutter. The main body cannot be disassembled, the small hole is easily clogged, and debris is difficult to clean. Utility Model Content
