Description

Technical Field

[0001] The utility model relates to the field of cigarette shred processing equipment, in particular to a quick cleaning device for planetary wheel grinding disc teeth of a shredder, which can effectively improve the maintenance efficiency. Background Art

[0002] In the production line of tobacco industry, the shredder is a process that turns the tobacco leaves after adding materials and moistening into tobacco shreds with qualified width, which is of great significance. The material is sent into the trough composed of upper and lower chain and frame by the vibrating trough trolley. Under the synchronous movement of the upper and lower chain, the material is conveyed to the knife door. The upper knife door and the upper chain can be raised and lowered together. Under the action of the knife door lifting cylinder, continuous and constant pressure is applied to the material, making the material into a "cake shape" to facilitate shredding. On the rotating knife roller, several blades are evenly installed to continuously cut the continuously output "tobacco cake".

[0003] During the operation of the cutter roller, due to the gap in the cavity structure, some "tobacco scale" will be left on the planetary wheel grinding disc teeth, which will be compacted during the transmission of the planetary wheel grinding disc gear system, and in serious cases, the bakelite gear ring will be damaged. The cutter roller system of the SQ21 shredder is a planetary wheel grinding disc gear system transmission system, in which the bakelite gear ring is the sun gear, and the other 8 planetary wheel grinding disc teeth are called the feed gear system, which corresponds to 8 feed shafts respectively. Gear meshing transmission is adopted between the sun gear and the planetary wheel grinding disc teeth. In order to improve the accuracy of the transmission and reduce the wear rate, the maintenance worker performs wheel maintenance on the planetary wheel grinding disc gear system once a week to ensure the normal operation of the equipment.

[0004] Every time the maintenance personnel perform maintenance on the planetary wheel grinding disc gear system in the cutter roller, they need to disassemble it before using a soft-bristled cleaning brush to clean and maintain the internal planetary wheel grinding disc teeth. At present, the average maintenance time for the planetary wheel grinding disc gear system of the cutter roller body of the SQ21 shredder is 94.7 minutes, which will affect the time when the workshop production schedule ends. Therefore, designing a fast cleaning device for the planetary wheel grinding disc teeth of the shredder is of great significance to the effective implementation of the production schedule and reducing the labor intensity of maintenance personnel.
