In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0034] As shown in Figure 1 The utility model provides a cigarette loading machine, including conveying channel 200 and flexible fairing mechanism 100. The bottom end of conveying channel 200 is provided with lower cigarette channel, and the flexible fairing mechanism 100 is located above conveying channel 200, and is preferably arranged above the lower cigarette channel to flow the cigarette conveying and avoid the deflection of cigarette, control cigarette conveying flow.
[0035] As shown in Figures 2-5 The flexible fairing mechanism 100 includes a plurality of fairing rollers 10 and a plurality of connecting pieces 20. The plurality of fairing rollers 10 are arranged in parallel and along the conveying direction of the conveying channel 200. Any two adjacent fairing rollers 10 are connected by the connecting piece 20 to form a whole. Specifically, the fairing roller 10 includes a central shaft 11 and a roller body 12 rotatably sleeved on the central shaft 11. The roller body 12 can contact the cigarette and rotate relative to the central shaft 11 driven by the conveyed cigarette, thereby realizing the fairing of the cigarette. The connecting piece 20 is rotatably connected with the central shaft 11 of the adjacent two fairing rollers 10, so that the included angle between the adjacent two connecting pieces 20 can be adjusted, thereby enabling the fairing surface formed by the plurality of fairing rollers 10 to be adaptively adjusted according to the actual stacking condition of the cigarette, to improve the fairing and deviation correction effect of the cigarette. The roller body 12 rolls in contact with the cigarette, and the friction is small. Not only the flow guiding effect is good, but also the cigarette deviation can be corrected, the horizontal cigarette phenomenon and the surface damage of the cigarette can be reduced, and the stability of the cigarette conveying quality can be ensured.
[0036] As shown in Figure 4As shown, the central shaft 11 includes a shaft body 111 and a limiting part 112 provided at both ends of the shaft body 111. The connecting piece 20 is sleeved on the shaft body 111 and located between the limiting part 112 and the roller body 12. Through the cooperation of the limiting part 112 and the roller body 12, the axial positioning of the connecting piece 20 and the rectifier roller 10 is realized, and the connecting piece 20 and the rectifier roller 10 are prevented from disengaging.
[0037] It should be noted that the outer diameter of the limiting part 112 is larger than the outer diameter of the shaft 111, so that the limiting part 112 has a structure that protrudes radially along the shaft 111, so that the roller 12 can cooperate to limit the position of the connecting member 20.
[0038] To facilitate the assembly of the connector 20 with the rectifier roller 10, one of the two limiting parts 112 is fixedly connected to the shaft body 111, while the other limiting part 112 is detachably connected to the shaft body 111. This allows the connector 20 to be sleeved over the shaft body 111 from one end of the detachable limiting part 112. This structure not only facilitates assembly but also allows for easy replacement of the roller body 12, connector 20, and shaft body 111 according to actual usage, thereby reducing maintenance costs.
[0039] In some embodiments, one of the two limiting parts 112 is a movable limiting part and the other is a fixed limiting part. The fixed limiting part is integrally formed with the shaft body 111 to reduce the number of parts, simplify the structure, and reduce costs. The movable limiting part is a limiting cap, which is sleeved on one end of the shaft body 111 and detachably connected to the shaft body 111 for easy assembly.
[0040] Optionally, the limit cap and the shaft 111 can be connected by threads or snap-fit, which also facilitates disassembly and assembly.
[0041] In some embodiments, the connector 20 can be a connecting rod, with rotating holes at both ends of the connecting rod, and the shaft 111 can extend into the rotating holes and rotate within the rotating holes.
[0042] like Figure 5 As shown, in order to make the structure of the flexible rectifier mechanism more compact, two adjacent connectors 20 are staggered along the axial direction of the rectifier roller 10 to reduce the impact of the assembly of the connectors on the length of the shaft 111, which is conducive to the rational use of space.
[0043] To reduce the resistance when the roller 12 rotates, a bearing is provided between the shaft 111 and the roller 12. The bearing can be a rolling bearing to reduce friction.
[0044] To avoid excessive wear of the roller body 12 and the cigarette, the roller body 12 is made of ceramic material. The roller body 12 is made of ceramic material, the surface is wear-resistant and high in smoothness, the roller body 12 rotates flexibly, the excessive friction on the surface of the cigarette is avoided, the force on the cigarette is more uniform and gentle in the conveying process, the conveying flow of the cigarette is stable, the damage to the surface of the cigarette is reduced to the maximum, and the original structure of the cigarette is maintained.
[0045] In some embodiments, the diameter of the roller body 12 is 5-10mm, so that the diameter of the roller body 12 is closer to the diameter of the cigarette, and the flow regulation and deviation correction effect of the roller body 12 on the cigarette is improved.
[0046] Optionally, the diameter of the roller body 12 can be 5mm, 5.4mm, 6mm, 6.2mm, 6.6mm, 7mm, 7.2mm, 7.7mm, 7.8mm, 8mm, 9mm or 10mm.
[0047] In combination Figure 1 And Figure 2 As shown in Figs. 1-3, the cigarette tray loading machine comprises two guide plates 300 oppositely arranged above the conveying channel 200, the space between the two guide plates 300 corresponds to the lower cigarette channel, and among all the flow regulating rollers 10, the two outermost flow regulating rollers 10 are respectively connected with a fixed seat 30, the fixed seat 30 is connected with the guide plate 300, so as to fix the flexible flow regulating mechanism 100 above the conveying channel 200.
[0048] To simplify the structure, the fixed seat 30 and the roller body 12 of the flow regulating roller 10 connected therewith are integrally formed, so as to reduce the number of parts and facilitate machining and assembly. The fixed seat 30 and the roller body 12 connected therewith are integrally formed, so that the fixed seat 30 can rotate relative to the shaft body 111 connected therewith, the installation angle of the fixed seat 30 is more flexible, and different models and different installation requirements can be better compatible.
[0049] In some embodiments, the length of the flexible flow regulating mechanism 100 is greater than the maximum distance between the two guide plates 300, so that when the amount of cigarettes is large, the flow regulating surface formed by the plurality of flow regulating rollers 10 in the flexible flow regulating mechanism 100 can be convex and expanded upwards with the accumulation of the cigarettes, so as to satisfy the buffer amount of more cigarettes.
[0050] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, various obvious changes, re-adjustment and replacement can be made without departing from the protection scope of the utility model. Here, it is unnecessary and impossible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the utility model claim.
