Example 1: a general leveling plate of a PT series cigarette making machine comprises two leveling plates and a brush wire wheel 6, wherein the two leveling plates are symmetrically arranged through a mounting hole 4 and a positioning hole 5 which are formed in a leveling plate body 1, and the brush wire wheel 6 is positioned at the lower end of the leveling plate body 1; the two leveling disc bodies 1 are arranged on the rotating shaft, are positioned on the same horizontal plane and are tangentially and symmetrically arranged, rotate reversely, and trim the cigarette bundle rudiment on the shred suction belt 7 above the leveling disc bodies 1 to ensure that the section of the cigarette bundle rudiment is close to the section of a cigarette strip 8 meeting the requirement and has uniform weight; the wire brushing wheel 6 is positioned below the tangential symmetry axis of the two leveling disks 1, and the cut tobacco which is pinned by the leveling disks is guided into the wire returning belt through the wire brushing wheel (6) and then returns to the feeding system again; grooves are uniformly and alternately distributed on the outer circumference of each leveling disc, each bevel groove 2 alternately forms an arc-shaped groove 3, and the arc length between the central points of the outer edges of every two grooves is equal to the cigarette length of a prefabricated cigarette; the inclined groove 2 is an inclined trapezoid-mouth bag-shaped groove, compared with the existing groove, the ignition end 81 of the cigarette rod 8 after the inclined groove is leveled is provided with a connecting section type cigarette bundle excessively connected to the middle section cigarette, and can meet the requirement of the cut tobacco with larger volume, so that the phenomenon that the cigarette is empty due to the small volume of the cut tobacco is avoided; the arc-shaped groove 3 is aligned with the twisted end 82 of the rear cigarette rod 8; the cigarette with tight end is formed after being rolled, the middle of the tight end is cut when the cutter cuts the cigarette rod 8, so that the ignition ends 81 and the twist ends 82 at the two ends of the cigarette are slightly tighter than the middle.
Six grooves are formed, namely, the bevel groove 2 and the arc-shaped groove 3 are respectively three and alternately formed, and the size of the leveling plate is determined according to the length of a cigarette: the flat disc diameter (d) = cigarette length (mm) × 6/3.14, such as: if 59mm cigarettes are produced, the diameter of the leveling disk is 59 multiplied by 6/3.14 ≈ 112mm, if 70mm cigarettes, the diameter of the leveling disk is 70 multiplied by 6/3.14 ≈ 134mm, if 59mm cigarettes, the diameter of the leveling disk is 54 multiplied by 6/3.14 ≈ 103mm.
The invention modifies the groove parameters of the leveling disc, as shown in figures 2 to 5, in order to ensure that the weight of the whole cigarette is kept unchanged, and simultaneously ensure the integral hardness and filling effect of the cigarette, and furthest ensure that few or even no loose-end cigarettes are generated at the cigarette ignition end 81, the groove shape of the cigarette ignition end 81 is changed into an isosceles trapezoid shape from a parabola shape or a rectangle shape, the relative volume of the tobacco shreds in the leveling disc groove is larger, the smooth transition of the tobacco shreds is also ensured, the loose-end cigarettes are fewer, the phenomenon of fire head dropping after ignition is also avoided, the cigarette rubbing section end 82 keeps the original parabola shape, and the arc length of the groove is shortened to fill redundant tobacco shreds to other parts of the cigarette according to the rubbing position of the cigarette and a filter tip rod, so that the integral hardness of the cigarette is ensured. The depth of the groove of the ignition end 81 of the leveling disc is changed from 4.0mm to 3.0-5.0 mm, the depth can be freely selected after the shape of the groove is determined, and experiments prove that: the cigarette with the groove depth of 4.6mm is good in effect, the cigarette with the groove depth of 4.0mm is good in effect when the cigarette with the groove depth of 70mm is good in effect when the cigarette with the groove depth of 54mm is good in effect when the cigarette with the groove depth of 3.0mm is obtained, the optimal ratio is 1.2-1.25 according to the density ratio formula of the front section, the middle section and the rear section of the cigarette, the arc lengths of the grooves are uniformly changed from 22mm to 14-18.2mm, the groove depth of the rubbing end of the leveling disc is not changed to 2.0mm, and the arc length is changed from 22mm to 14-18.2mm. After the leveling disc groove is improved, the tobacco shred filling effect at the compaction end is better, the shapes of the leveling discs of the whole series of cigarette making machines are unified, and the groove depth range is made. The application effect is good, the consumption of the empty-end cigarettes is less than 0.2 percent (the empty-end rejection rate before and after improvement is shown in table 1), and no quality defect occurs.
Table 1: improved rate of eliminating loose ends of cigarettes
As is apparent from Table 1, the cigarette loose-end rejection rate is significantly reduced from the original 2% to less than 0.2% after the shape and depth of the leveling plate are improved.
Example 2: the influence of the depth of the groove of the leveling disc on the density difference of the cigarette elastic end is as follows: as shown in fig. 10, the deeper the groove, the denser the tobacco shred, the shallower the groove, the thinner the tobacco shred, and further the influence of the groove depth on the cigarette blank rate is verified by experiments:
table 2: influence of depth of groove of leveling disc on space head ratio
Using one-factor analysis of variance one can get:
single factor analysis of variance: a (groove depth 3.0 mm), B (groove depth 2.8 mm), C (groove depth 2.5 mm)

Because P =0.032 +/-0.05 in the depth single-factor analysis of the grooves of the leveling disc, the depth of the grooves of the leveling disc has obvious influence on the cigarette without ends, the depth size of the grooves of the leveling device has obvious influence on the cigarette without ends, and the smaller the depth of the grooves is, the smaller the cigarette without ends rate is. For best results, the size of the flat disk grooves needs to be optimized.
An orthogonal experiment method is carried out by taking a 59mm cigarette as an example to determine the specification of the optimal leveling disc:
