The utility model discloses an integrated cigarette making and plug assembling
machine secondary
winnowing device screening and tobacco shred returning
management system, which belongs to the technical field of cigarette making and plug assembling machines, and comprises a screening and tobacco shred returning management body connected with a cigarette making and plug assembling
machine secondary
winnowing device, the screening and tobacco shred returning management body comprises a dust collecting
assembly and a screening device fixedly connected on a side plate of a cigarette making and plug assembling
machine, a feeding port, an air return port and a discharging port are formed in the screening device, the feeding port is communicated with a tobacco shred output pipeline of the secondary
winnowing device through a tobacco shred pipeline
assembly, the air return port is connected with the dust collecting
assembly through a negative pressure air return pipeline assembly, the output end of the dust collecting assembly is connected with the central dust remover, and a long discharging bent
pipe is obliquely arranged on the discharging port. The negative pressure intensity is adjusted through the air supplementing valve, tobacco shred breakage is reduced, and the quality stability of waste tobacco shred is improved; by optimizing the dust removal design, tobacco shreds and impurities are accurately separated, and the central dust removal load is reduced; and through the design of the inclined discharging long bent
pipe and the modular pipeline,
airflow interference is reduced, maintenance is simplified, and the
resource utilization rate is increased.
