[0002] The ZJ118 cigarette making unit is a cigarette making unit designed and manufactured by Hauni Corporation of Germany. It is manufactured by Changde Tobacco Machinery Co., Ltd. on an automatic production line for filter cigarettes with a design capacity of 8,000 cigarettes per minute. As it is an ultra-high-speed cigarette making machine that absorbs foreign technology, some problems or defects gradually emerged during the operation of the equipment. Among them is the time-consuming and labor-intensive replacement of the cylinder of the tipping paper lifter. Figure 4 As shown, one end of the cylinder 1 is connected to the wall panel 3 of the connection machine through the support 2, and the other end of the cylinder 1 is connected to the connecting rod 9 of the gluing assembly through the pin 4, wherein the ends of the support 2 and the pin 4 are both limited by shaft elastic retaining rings, and circlip pliers must be used when disassembling and assembling the elastic retaining rings. Since the cylinder 1 is installed in the narrow gap between the gluing assembly and the wall panel 3 of the connection machine, the circlip pliers are difficult to use, resulting in the original replacement method requiring the disassembly and assembly of the gluing assembly, which is difficult to implement and takes a long time to replace. Therefore, it is necessary to make improvements to the above problems. Utility Model Content
