Technical Field
[0001] The utility model relates to the technical field of cigarette processing, in particular to a chopping knife disc used for a leveler of a ZJ17 cigarette making machine. Background Art
[0002] In cigarette production, the ZJ17 cigarette making machine is the mainstream model of medium-speed machines, with high production efficiency and quality, and plays a very important role in the tobacco industry.
[0003] ZJ17 cigarette making machine is a commonly used cigarette production machine. The chopper disc is one of the most important parts of the leveler. Its quality is directly related to the quality of the leveler components.
[0004] The chopping knife disc is located at the front and rear chopping knife guide positions of the tobacco suction chamber. Two chopping knives rotating in opposite directions are used to flatten the raised parts of the tobacco bundle after the tobacco is sucked and formed, so as to change the uniformity of the tobacco bundle. The chopping knife disc is provided with deep grooves and shallow grooves, which correspond to the burning end and the filter rod end respectively, so that the two ends form tight heads, prevent empty heads and loose ends, and reduce end tobacco falling.
[0005] The chopper disc of the cigarette making machine will affect the stability of the density of the cigarette segment, and then affect the stability of the puff resistance of the cigarette. The puff resistance of the cigarette is the resistance to each puff during the smoking process of the cigarette. Compared with the static resistance when the cigarette is not lit, it can better reflect the intuitive feelings of consumers. In recent years, with the upgrading of the tobacco consumer goods market, consumers' focus has gradually shifted from appearance quality to sensory quality. Therefore, the importance of the stability of the density of cigarette segment is increasing.
[0006] In addition, since the draw resistance of cigarettes is related to the combustion state of cigarettes, stable draw resistance during the combustion and drawing process can also maintain the stability of the release of chemical components in cigarette smoke, and at the same time have a great impact on sensory qualities such as the sense of relaxation, comfort, and satisfaction during smoking. Summary of the invention

[0020] The utility model is described below in conjunction with specific embodiments.
[0021] A chopper disc for a ZJ17 cigarette making machine leveler, such as Figures 1 to 3 As shown: The chopper disc is made of 40CR high-quality steel by one-piece stamping. The one-piece stamping is integrally modeled, easy to process, can be mass-produced, and has low cost.
[0022] The thickness of the cleaver disc is less than or equal to 1.9mm. The normal clearance between the cleaver disc and the VE air chamber guide is 1.5mm, and the minimum clearance between the front and rear cleaver guides and the cleaver disc seat is 3.4mm. The thickness of the cleaver disc = the minimum clearance between the air chamber guide and the cleaver disc seat - the minimum clearance between the air chamber guide and the cleaver disc is 3.4mm-1.5mm=1.9mm. The maximum thickness of the cleaver disc is calculated to be 1.9mm.
[0023] It includes a circular plate body 1. According to the ZJ17 cigarette machine installation specification and the manufacturing standard of standard cigarettes, the circular plate body 1 has a diameter of 118 mm and a radius of 59 mm. The central part of the circular plate body 1 is provided with a plate inner hole 2 for installing a splitter bearing. The diameter of the plate inner hole 2 is 24 mm.
[0024] An even number of grooves 3 are formed on the edge of the circular disc body 1. The groove bottom thickness of the groove 3 is less than the thickness of the circular disc body 1. The inner and outer surfaces of the groove bottom 31 are parallel to the disc surface of the circular disc body 1. In this embodiment, 6 grooves 3 are provided. The grooves 3 include evenly spaced ignition end grooves and filter rod end grooves. The groove depth of the ignition end groove is greater than the groove depth of the filter rod end groove. The groove depth of the ignition end groove is 4 mm, and the groove depth of the filter rod end groove is 2 mm. The groove width of the groove 3 is greater than or equal to 4.5 mm, and the arc length of the groove is 22 mm. The blades of the ignition end grooves of the two chopping knife discs used as a set are completely aligned, and the blades of the filter rod end grooves are completely aligned.
[0025] The groove 3 includes a groove bottom 31 and an arc-shaped side wall 32 connecting the groove bottom 31 and the circular plate body 1. The back side of the groove bottom 31 protrudes from the bottom surface of the circular plate body 1. The edge edge 33 of the groove bottom 31 is at an acute angle. The edge edge of the groove bottom 31 is 30-60 degrees. The edge edge of the groove bottom 31 is 45 degrees. The sharp edge edge 33 is conducive to the complete shearing of the finished tobacco, preventing the finished tobacco from being pulled due to poor cutting, and avoiding the formation of a tobacco bundle hollow. The arc-shaped side wall 32 is an inclined surface.
[0026] The groove 3 is in the shape of a semicircular hole, which is different from the existing crescent-shaped groove. The semicircular hole-shaped groove has a larger groove area, and the length of the tobacco bundle head formed by the groove is increased, so the resistance is smaller when the tobacco bundle enters; the junction edge of the arc side wall and the circular disk body 1 includes two mirrored arc edges 5, and the two arc edges 5 are symmetrical about the diameter of the circular disk body 1 passing through the center of the groove 3, that is, the two sides of the groove are symmetrical, and the two arc edges 5 are connected by a connecting edge 4, and the connecting edge 4 is an arc concave toward the inner hole 2 of the disk.
