Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette equipment maintenance tools, specifically relating to an auxiliary disassembly device for the separating drum of a cigarette assembly machine. Background Technology

[0002] The function of the YJ218 cigarette separator drum is to separate two cigarettes by a distance to allow the filter section to be inserted. After receiving the cigarette from the cigarette cutting drum, the separator drum is drawn in by negative pressure air as it rotates with the cigarette separator blocks. During rotation, the cylindrical cam mechanism pushes the two rows of cigarette separator blocks towards both ends of the drum, thus creating axial separation between the two rows. When a double-length filter section can be inserted between the two rows of cigarette separator blocks, the cigarette has moved to the junction of the converging drum. At this point, the negative pressure air in the cigarette receiving groove of the separator drum is cut off, and the cigarette is transferred to the converging drum. Then, the cam mechanism continues to push the two rows of cigarette separator blocks towards the middle. During the closing process, compressed air cleans the cigarette receiving groove.

[0003] The separating drum contains three cylindrical end face cams. Analyzing the motion principle of the cylindrical end face cam mechanism, the first and second cylindrical end face cams are fixed, while the third cylindrical end face cam only serves a protective function, preventing the slide rod from being ejected under the spring force. The curve rise of the first cylindrical end face cam is the same as that of the second cylindrical end face cam, but in opposite directions. As the drum body drives the two sets of sliders and rollers to rotate around the cam center, under the force of the pressure spring, the lower and upper rollers move along the rise curves of the first and second cylindrical end face cams respectively, pushing the two sets of sliders to perform relative reciprocating motion.

[0004] During equipment maintenance, research into the movement of the separating drum revealed that disassembling the separating drum is time-consuming, labor-intensive, and poses human and machine safety hazards. The reasons were analyzed as follows: the internal spring of the separating drum poses a safety hazard during disassembly. Improper disassembly may cause the drum to pop out, causing personal injury, and may also damage the equipment or result in the loss of parts. Utility Model Content
