[0042] The utility model relates to a packaging machine swing arm fulcrum shaft reinforcement device and a cigarette packing machine, the working principle of which is as follows:

[0043] S1: The operator shall follow the Figure 1-Figure 7 , and the descriptions of the above components, assemble and install the components. The base 1 is fixed to the packaging machine box through the base slot 101 and the connector; the horizontal adjustment plate 2 is fixed to the base 1 through the base connection hole 102, the adjustment plate slot 201, and the connector; the reinforced end cover 3 is fixed to the horizontal adjustment plate 2 through the adjustment plate connection hole 202, the end cover slot 301, and the connector; this achieves alignment between the end cover through hole 302 and the fulcrum shaft threaded hole at the front end of the fulcrum shaft 21;

[0044] S2: The driving source drives the positioning baffle driving cam 18 to rotate via the driving shaft. The positioning baffle driving cam 18 rotates and drives the positioning baffle first swing arm 14 to swing via the positioning baffle driving roller 1401. Then, the positioning baffle 4 is driven to rise via the positioning baffle connecting rod 15, the positioning baffle second swing arm 16, the positioning baffle transmission shaft 17, and the positioning baffle crank 19. At the same time, the pushing hand moves to the left to drive the two cigarette packs and the inner frame paper into the packing mechanism 6.

[0045] S3: The combining mechanism 6 works to combine the two cigarette packs, and the pushing hand pushes the combined cigarette packs to the left.

[0046] S4: The driving source drives the folder driving cam 7 to rotate via the driving shaft.

Then, the inner frame paper folder 5 is driven downward via the folder connecting rod 9, the second folder swing arm 10, the folder transmission shaft 11, the folder crank 12, and the folder adapter block 13, thereby folding the inner frame paper entering the inner frame paper folder 5 downward.

[0047] S4: When the pushing hand pushes the cigarette pack with the inner frame paper folded into the next process, the positioning baffle driving cam 18 moves away from the positioning baffle driving roller 1401, and the folder driving cam 7 moves away from the folder driving roller 801. The reset springs on the positioning baffle first swing arm 14 and the folder first swing arm 8 work to reset the positioning baffle first swing arm 14 and the folder first swing arm 8. In this way, the positioning baffle 4 moves downward to return to its initial state, and the inner frame paper folder 5 moves upward to return to its initial state, facilitating the next work cycle.

[0048] The present invention relates to a packaging machine swing arm fulcrum shaft reinforcement device and a cigarette packing machine. Another fulcrum is added to the front end of the fulcrum shaft 21. Thus, the force on the fulcrum shaft 21 is evenly distributed between the two fulcrums, ensuring balanced force on the fulcrum shaft 21 and strengthening and balancing the load-bearing capacity of the fulcrum shaft 21, making it less likely to become loose or break. The provision of a base slot 101, an adjustment plate slot 201, and an end cap slot 301 allows for the position adjustment of the end cap through hole 302 within a small range, ensuring alignment between the end cap through hole 302 and the fulcrum shaft threaded hole at the front end of the fulcrum shaft 21, and provides a wide range of applications.

[0049] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
