Description

Technical Field

[0001] The utility model relates to the technical field of spider hands of cigarette machines, in particular to an oil-free spider hand for cigarette processing. Background Technique

[0002] During the production process of a cigarette machine, after the cigarette rod is formed, in order to facilitate later slitting and splicing with the cigarette filter, it is necessary to convert its horizontal movement into a circular movement around a drum.

[0003] According to the published patent 202321452303.8, an oil-free spider hand cigarette rod conveying device for cigarette processing includes a rotating wheel body. One end of the rotating wheel body is rotatably connected to an eccentric shaft. The eccentric shaft includes a front section shaft and a rear section shaft. The front section shafts are circumferentially arrayed around the rotation axis of the rotating wheel body, and conveying arms are connected to the front section shafts; the rear section shafts are rotatably connected to eccentric discs. The rear section shafts are circumferentially arrayed on the eccentric discs, and the eccentric discs are rotatably connected to eccentric wheels. In the process of implementing the utility model, the inventor found that at least the following problems in the prior art have not been solved. The problems of easy oil leakage are solved by the front wheel body, eccentric shaft, eccentric disc, rear wheel body, positive synchronous pulley, support rod, reverse synchronous pulley, reverse rotating shaft and eccentric wheel. During use, the traditional spider hand can only delay leakage in actual application. Generally, leakage occurs after being used for a period of time.
