Description
Technical Field
The utility model relates to a tobacco equipment technical field especially relates to an automatic cleaning device of air separator rolling screen.
Background
The flexible in-situ winnowing machine can be used in different use occasions to finish different process purposes. Such as: after the moisture regaining process section of the expanded cut tobacco, the product can be used for separating conglomeration, stem sticks, dry ice blocks and other impurities in the regained expanded cut tobacco. Because the flexible local air separation is not carried by wind, the crumbling is not generated basically. The net rolling mechanism of general flexible in-situ wind separator consists of upper box, net rolling assembly, cleaning roller, driving mechanism, etc. The rolling net is assembled by a stainless steel screen plate and a framework, two ends of the rolling net are supported by bearings, and a speed reducer drives the rolling net and the cleaning roller to rotate through a chain wheel and a chain. The cleaning roller is positioned at the lower part of the rolling net, and two ends of the cleaning roller are supported by bearings. The net rolling mechanism is arranged at the upper part of the winnowing box body. And the bearing in the air pipe at one end of the rolling net is automatically lubricated. The screen plates are 4 pieces in total, and the specification size of the screen plates is 780mm x 960 mm. The mesh opening of the screen is phi 2 mm in aperture.
The outer surface of the stainless steel rolling net is continuously cleaned by the scraper leather strips on the cleaning roller, so that the outer net surface can be kept in a cleaner state basically. In the production, the volume-to-weight ratio of the expanded cut tobacco to the common cut tobacco is small. And the expanded tobacco shreds are more seriously crushed than common tobacco shreds due to the restriction of a processing method. The outer surface of the rolling net is often cleaner, the dust removal air quantity is still insufficient, and the flotation effect is poor. The partially expanded tobacco shreds fall into a secondary winnowing box body (an impurity removing hopper) to cause tobacco shred waste. After the opening degree of the dust removal air door is adjusted, the production requirements can be temporarily met. After production is finished, the outer surface of the roller screen is cleaned, and the surface of the roller screen is blown by air pressure so as to clean the smoke dust blocked in the mesh holes on the inner surface of the roller screen. The opening of the dust removal air door is observed and properly adjusted at any time when the production is recovered. So as to meet the technical quality requirement of the expanded cut tobacco.
Through the observation of the disassembly and cleaning process of the rolling screen. And under the condition that the outer surface of the rolling net is clean, the inner surface of the rolling net still cannot ensure the smoothness of all the mesh holes of the phi 2 mm sieve. Due to frequent occurrence of large-area blockage on the inner surface of the mesh of the drum screen, the blockage rate is close to 70% in serious cases. The winnowing effect is seriously influenced, the purity of the cut tobacco is reduced, and the foam in the cut tobacco is increased. Use the cleaning brush to clean the screen cloth of jam, can comparatively swift clearance go out the cigarette foam of jam in the screen cloth hole. But because the rolling screen consists of 4 screen plates. The screen plate is fixed on the rolling screen frame by a plurality of screws M5. The disassembly and assembly process is complicated, the workload is large, the M5 screw is easy to cause thread damage after repeated disassembly and assembly, the repair is difficult, the space position where the operation can be carried out is narrow, the elasticity of the stainless steel rolling net is large, and the difficulty is brought to the disassembly and assembly work.
