Wind-speed adjusting device on tobacco processing equipment

Abstract

The invention discloses a wind-speed adjusting device on tobacco processing equipment, relates to a wind-speed adjusting device that can stabilize the transmission of tobacco in pipeline, which belongs to field of tobacco machinery. The invention provides the wind-speed adjusting device on the tobacco processing equipment which can master the work parameter of a tobacco feeding port, a tobacco discharging port of tobacco-collecting boxes of various cigarette making machines in real time, thereby realizing high-precision control of wind speed and improvement of tobacco quality. The wind-speed adjusting device is arranged at a tobacco transmission tube and a de-dusting tube at both ends of the tobacco-collecting box of the tobacco processing equipment, comprising a controller, a wind-leakage detection device, a wind-speed instrument, a flowmeter, and a pneumatic adjusting butterfly valve, wherein, the wind-leakage detection device is arranged on the tobacco transmission tube, the wind-speed instrument is arranged on the tobacco-collecting box, the flow meter and the pneumatic adjusting butterfly valve are arranged on the de-dusting tube, the wind-leakage detection device, the wind-speed instrument, the flow meter and the pneumatic adjusting butterfly valve are connected with the controller. The invention has advantages of simple structure, high adjusting precision.

Description

technical field [0001] The invention relates to a wind speed regulating device capable of stably conveying shredded tobacco in a pipeline, which belongs to the field of tobacco machinery. Background technique [0002] At present, there are mainly three kinds of wind speed adjustment modes commonly used in China: one is to set a heavy hammer regulating valve at the air inlet of the dust collector, and the other is to set a three-way mechanism for supplementing air on the air supply and dust removal branch pipe of a single cigarette machine. The third is to set a flow meter and a flow regulating valve on the dust removal branch pipe. According to the investigation, because the tobacco processing equipment adopts the pipe network to feed the wire, and the length of the pipe network is inconsistent, these three design modes cannot solve the unbalanced pipe network caused by the position of the cigarette machine and the length of the wire suction pipe. The air leakage of the sil...

Problems solved by technology

According to the investigation, because the tobacco processing equipment adopts the pipe network to feed the wire, and the length of the pipe network is inconsistent, these three design modes cannot solve the unbalanced pipe network caused by the position of the cigarette machine and the length of the wire suction pipe. The air leakage of the silk box and the dust accumulation at the pressure inlet of the flowmeter lead to the problem of zero drift, resulting in large differences in the wind speed of the pipe network. A large amount of crushing occurs, and serious air separation occurs when the cigarette machine is blanking, which directly affects the quality of cigarettes
