Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production equipment, and more specifically to a stepless pressure-regulating circular knife cleaning device for a cigarette making machine. Background Art

[0002] The principle of secondary cutting of cigarette making machine is as follows: after double-length filter cigarettes are conveyed to the secondary cutting wheel, they enter the cutting guide rail. Under the joint action of the secondary cutting wheel, cutting guide rail and cutter, the double-length cigarettes are cut into normal cigarettes.

[0003] Because medium-sized cigarette filter rods are relatively hard, to ensure cutting quality, the original stainless steel blade + grinding wheel grinding method was eliminated and replaced directly with alloy blades. Furthermore, because the gluing ability of medium-sized cigarette tipping paper is weaker than that of regular cigarettes, the glue is not easily absorbed by the tipping paper during cutting. As the equipment continues to operate, excess glue adheres to the two end faces of the cutter. This glue accumulation makes the cutter rotation inflexible and damaged, increasing the frequency of cleaning by repairmen and blade changes by operators. Furthermore, the increased glue accumulation on the cutter leads to quality issues with the cut of the cigarettes.

[0004] Therefore, there is an urgent need for a stepless pressure regulating circular knife cleaning device for a cigarette making machine. Utility Model Content

[0027] The base 6 is mounted in the original grinding wheel seat position, and the scraper 1 is mounted on the top of the rocker 3. Made of hard alloy, the scraper 1 is highly wear-resistant.
