Pneumatic type dispensing equipment for transportating bobacco shred

Abstract

A pneumatic tobacco shred delivering-distributing apparatus for multiple cigartte markers is composed of tobacco shred feeder, cigarette marker, duster and control system. Its advantages are high uniformity of supplying shreds, and automatic regulation of air flow in pneumatic delivery pipeline.

Description

technical field [0001] The invention relates to a pneumatic shredded tobacco conveying and distributing device in the tobacco industry, which distributes the shredded tobacco to multiple cigarette makers at the same time through a feeder provided by a ventilator. Background technique [0002] Pneumatic conveying belongs to fluid conveying. It uses air as the working medium to convey materials to designated places through the flow of gas, or it is a technology of conveying materials through pipelines with positive or negative airflow. Pneumatic shredded tobacco conveying is a wire feeding method in the cigarette process. Compared with mechanical wire feeding, it has the advantages of small footprint, no escape of shredded tobacco and dust, and beautiful appearance. [0003] For the shredded tobacco conveying device in the domestic cigarette industry, the technology is mostly relatively backward. [0004] In terms of feeding, the wire feeding equipment commonly used in China ...

AI Technical Summary

Problems solved by technology

[0004] In terms of feeding, the wire feeding equipment commonly used in China is feeding by flipping boxes or conveyors. The wire feeding tube is fed by the rotation and vibration of the wire feeding disc of the wire feeding equipment, and the feeding is not uniform;

[0005] In terms of wind speed control, a manual control valve is installed on the main return air duct to control the air volume. The total air volume of the system is manually adjusted at the initial stage of commissioning. Cigarette machines supply shredded tobacco, and the same conveying and distributing device includes multiple cigarette machines. It will inevitably change the air volume in the conveying air duct of other cigarette machines, resulting in changes in the wind speed in the wire feeding pipeline, causing shredded tobacco to be broken and affecting the economic benefits of the cigarette industry

Moreover, the air volume of the ventilator cannot be adjusted with the intermittent work of the cigarette making machine, resulting in a waste of energy. Only a pneumatic cut-off valve is installed on the branch return air duct of a single cigarette making machine, which only plays a switch role and cannot realize the control of wire feeding. The wind speed in the tube is controlled;

[0006] In terms of dust removal, since the distribution device does not have the ability to adjust the wind speed entering the dust collector, the start and stop of the cigarette machine at any time will cause a sudden change in the wind speed of the system, which will cause a sudden change in the wind speed of the dust-laden gas entering the dust collector, which seriously affects the dust removal efficiency. and the life of the bag filter, and the dust cleaning time and cleaning cycle of the dust collector are set manually, which is experienced and difficult to achieve a good cleaning effect
