Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging, in particular to an automatic deviation-correcting mechanism for a cigarette packaging machine. Background Art

[0002] Cigarette packaging machines are mechanical devices specifically designed for packaging cigarettes, offering advantages such as a high degree of automation, high production efficiency, and ease of operation. A cigarette packaging machine is a mechanical device that packages cigarettes, completing the packaging process automatically or semi-automatically. Its primary functions include protecting cigarettes from environmental influences and improving their aesthetics and market competitiveness. After the cigarettes are packaged, they are coded as part of product traceability and anti-counterfeiting measures. The coding includes production information, batch numbers, and retailer information, helping to track the product's origin and distribution path, necessitating the use of an automatic deviation-correcting mechanism within the cigarette packaging machine.

[0003] Currently, Chinese patent publication number CN205471870U discloses a cigarette packaging printing correction mechanism, comprising a correction roller comprising an internal roller core and a roller sleeve sleeved over the roller core. The roller sleeve and the roller core are axially engaged by a keyway and a key bar. The keyway and key bar are axially arranged, and the roller sleeve and the roller core are axially slidably connected, so that the roller core and the roller sleeve rotate synchronously. A retaining ring is fixed to one end of the shaft core, and a spring sleeve is compressed between the retaining ring and the roller sleeve. A trapezoidal block is provided at the other end of the shaft core, and a wedge-shaped adjustment block is provided between the trapezoidal block and the roller sleeve. The wedge-shaped adjustment block cooperates with the trapezoidal block and the roller sleeve to squeeze and drive the roller sleeve to slide axially along the roller core. The wedge-shaped adjustment block is connected to a drive mechanism. By using the correction mechanism described in this application, correction can be achieved by adjusting the position of the roller sleeve on the roller core, requiring less power, being easy to operate, and having high efficiency.

[0004] However, when the above-mentioned prior art is in use, it relies on adjusting the position of the roller sleeve on the roller core to achieve deviation correction. However, due to the physical characteristics of the conveyor belt itself, there is inevitably a certain amount of vibration, which will cause slight displacements in the process of the cigarette contacting the conveyor belt. These slight displacements accumulate and may cause the cigarette to deviate from the predetermined position when it reaches the inkjet printer. When the inkjet printer is performing the inkjet coding operation, extremely precise positioning is required to ensure the accuracy of the coding. If the position of the cigarette is offset, the position of the coding will also be offset.

[0005] To this end, the utility model provides an automatic deviation-correcting mechanism for a cigarette packaging machine. Utility Model Content

[0044] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0045] The working principle of the utility model is as follows: when in use, the conveyor belt body 1 is started and the placement rack 2 is located under the conveying flue. After the cigarette strips are transported to the placement rack 2 through the conveying flue, they will be located at the inclined surfaces of the two connecting plates 5. As the conveyor belt body 1 is transported to the bottom of the pressing plate 16, the electric hydraulic rod 15 is started to make the pressing plate 16 exert force on the cigarette strips. The cigarette strips can press the inclined surfaces of the connecting plate 5 to contact the unloading plate 17. As the connecting plate 5 moves in the connecting groove 3, the tooth groove 12 can exert force on the gear 11. At this time, the gear 11 will rotate, and the rotation of the gear 11 can make the threaded rod 13 rotate. The rotation of the threaded rod 13 can make the limit rod 10 slide in the inner wall of the limit opening 8. The movement of the limit rod 10 can make the limit plate 9 slide in the inner wall of the limit groove 7. At this time, the side and end of the cigarette can be clamped at the same time. Therefore, as the cigarette strips are always in the appropriate position during the process of moving, the position of the cigarette strips can be prevented from being offset, thereby achieving the effect of preventing the inkjet position from being offset.

[0046] After the cigarette strips are spun on, the placement rack 2 moves to the side of the conveyor belt body 1. At this time, the inclined surface of the positioning rod 21 contacts the adjusting rod 23, and the positioning rod 21 can slide in the inner wall of the positioning port 20. The movement of the positioning rod 21 can make the unloading plate 17 slide out through the inner wall of the unloading trough 18. The unloading plate 17 can apply force to the bottom of the cigarette strips, so that the cigarette strips and the placement rack 2 can be separated for the next step, which can facilitate the unloading operation of the cigarette strips.
