[0011] Based on the above, in order to facilitate the external connection of the force application rod, a hexagonal hole is opened on the outer end surface of the handle.

[0012] Based on the above, in order to facilitate maintenance and disassembly, the handle is detachably connected to the outer end of the threaded push rod via a screw.

[0013] Based on the above, the length of the threaded push rod is greater than the length of the claw portion.

[0014] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model provides a receiving drum disassembly device for a filter rod forming machine. During specific operation, the end cover of the receiving drum is first removed, and then the slots on both sides of the U-shaped bracket in the receiving drum disassembly device are clamped on the boss of the flange seat, and the handle of the receiving drum disassembly device is rotated to realize rapid and non-destructive disassembly of the receiving drum, thereby reducing damage to the receiving drum.

[0015] At the same time, the device adopts a symmetrical structure, with a high degree of fit with the flange seat boss, and the force is evenly applied during the removal of the receiving drum, and it is relatively stable when pulling out the receiving drum. During the removal process, you only need to turn the handle to smoothly pull out the receiving drum, which improves the maintenance efficiency of the equipment.

[0016] Therefore, the device can realize the non-destructive disassembly of the receiving drum of the filter rod forming machine, and also has the advantages of simple structure and light weight. BRIEF DESCRIPTION OF THE DRAWINGS
