Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packet packaging, in particular to a buffer device for a cigarette packet packaging machine and the cigarette packet packaging machine. Background Art

[0002] The YF64 cigarette packet storage device is an important part of the ZB418 cigarette packet packaging machine. It is mainly a temporary storage device for cigarette packets that connects the upstream (small box) cigarette packet packaging machine and the downstream transparent paper packaging machine. Its function is that when the downstream transparent paper packaging machine stops, the upstream cigarette packet packaging machine is still running. At this time, the cigarette packets continuously output by the upstream cigarette packet packaging machine will be intercepted when passing through the YF64 cigarette packet storage device, and then be pushed into the storage box of the cigarette packet storage device. When the downstream transparent paper packaging machine resumes operation, the cigarette packets in the storage box will output the cigarette packets orderly according to the number of cigarette packets in the conveying channel and supply them to the transparent paper packaging machine for use.

[0003] As Figure 1 and Figure 2 shown, the conveying line of the cigarette packet packaging machine includes an upper conveying frame 100 and a lower conveying frame (not shown in the figure). Conveyor belts 300 are provided on both the upper conveying frame 100 and the lower conveying frame, and two conveyor belts are arranged at intervals on each conveying frame. Both ends of the cigarette packet 400 are placed on the two conveyor belts on the lower conveying frame for conveying, and the two conveyor belts on the upper conveying frame 100 are in contact with the top surface of the cigarette packet and also apply a conveying force to the cigarette packet. When a fault occurs in the downstream transparent paper packaging machine, the cigarette packets conveyed from the upstream cigarette packet packaging machine are intercepted at a set position on the lower conveying frame corresponding to the inlet of the storage box. When the number of cigarette packets meets the pushing quantity, the cylinder 500 is started, and the top plate 600 located below the lower conveying frame and the upper conveying frame 100 are jacked up. The top plate 600 moves upward to jack up the cigarette packet from the conveyor belt on the lower conveying frame, and the upward movement of the upper conveying frame 100 is to release the downward pressure on the cigarette packet, so that there is no external force interference when the cigarette packet is pushed towards the storage box, and then the push rod pushes the multiple groups of cigarette packets into the storage box. When the cigarette packet pushing is completed, the piston rod of the cylinder 500 retracts, and the top plate 600 and the upper conveying frame 100 return to their original positions. This is the working process.

[0004] However, in actual work, due to the very fast extension speed of the cylinder piston rod, there is an upward impact force at the moment of reaching the working position, which often causes the fixing bolts at each joint to break. At the same time, it will also cause the cigarette packet to bounce during the upward jacking process, thus easily causing the position of the cigarette packet to shift or fall, and further resulting in material jamming when pushing the cigarette packet. Summary of the Invention

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a buffer device for a cigarette packet packaging machine and a cigarette packet packaging machine, which can relieve the impact force driven by the piston rod of the cylinder, extend the service life of the parts of the machine frame, and improve the stability of the upward feeding of cigarette packets.

[0006] To achieve the above object and other related objects, one aspect of the present utility model provides a buffer device for a cigarette packet packaging machine.
