Description
Technical Field
The utility model belongs to the technical field of the cigarette machine, concretely relates to skeleton oil blanket assembly and disassembly tools.
Background
In the actual production, the spider hand of cigarette machine runs at a high speed for a long time, the spider hand is in the cigarette conveying process, the mechanism transmission case and the revolving arm transmission shaft rub with two skeleton oil seals when rotating at a high speed, so that the skeleton oil seals age and leak oil, the heat dissipation condition inside the spider hand is poor, the temperature of the lip of the skeleton oil seal is high, the oil seal fails due to aging, deformation and abrasion, so that the oil leaks, the oil leaks into a clean air channel to pollute cigarettes, and leaked oil overflows from a suction groove under the action of clean air blowing and contacts with the surfaces of the cigarettes to cause oil stain cigarettes, and in order to ensure the product quality, the failed oil seal is replaced in time.
At present, in the production and maintenance process, two methods for replacing the spider hand skeleton oil seal of the cigarette making machine are generally adopted:
1. and (5) disassembling the spider hand assembly, and replacing the oil seal according to the related requirements of the equipment maintenance specification strictly. According to the relevant requirement of the maintenance of equipment specification, when changing the oil blanket, adopt the mode of dismantling spider hand assembly to maintain to this kind of mode is changed the oil blanket after, adjacent and the part that hinders the oil blanket and dismantle is intact, and the operation is stable after the maintenance of equipment, but the maintenance duration overlength that consumes time seriously influences equipment operating efficiency.
2. The destructive disassembly mode for replacing the oil seal is to use tools such as a flat opener and a chisel to destroy the framework of the oil seal and then use the flat opener to disassemble the oil seal. In the maintenance process, a traditional tool is adopted to destroy the oil seal framework in a violent mode, the surface of a surrounding part is damaged when the force is excessively applied, and the working surface of the part needs to be repaired and polished; and simultaneously, the oil sealing effect of the oil seal is reduced. The oil seal is replaced by adopting the mode, the maintenance time is short, but the maintenance is unreliable; if the parts are seriously damaged, the spider hand assembly still needs to be disassembled and hung to replace the damaged parts, and the operation efficiency of the equipment is influenced. Therefore, the maintenance method of destructively disassembling and replacing the oil seal by using the traditional tool has unstable maintenance effect and cannot really realize rapid maintenance.
Therefore, through the analysis and research on the two oil seal replacement modes, the two oil seal replacement modes can not achieve the purpose of improving the operation efficiency of equipment, and meanwhile, the great risk that adjacent parts are damaged exists. Therefore, how to design a framework oil seal assembly and disassembly tool ensures that when carrying out destructive disassembly, the probability of damage to the adjacent parts of the oil seal is reduced, and the technical problem that the operation efficiency of equipment is ensured to be urgently needed to be solved by technical personnel in the field.
