Abstract
The present invention relates to a pneumatic type dispensing device for transporting tobacco shreds, which comprises a tobacco shred feeding machine, a cigarette making machine, a dust remover and a control system. The system of the device can ensure uniform feeding, can adapt to the requirement for supplying tobacco shreds to a plurality of cigarette making machines, and can also satisfy the requirement random supplying to cigarette making machines. The wind quantity in a conveying wind pipe can be automatically regulated so as to avoid the influence on economic benefits and the waste of energy sources caused by the fragmentation of tobacco shreds due to the changes of the wind speed. The present invention is a substitute for similar equipment in cigarette industry.
Description
Technical field
The present invention relates in a kind of tobacco industry, finished cut tobacco from wire-storing cabinet through feeder apparatus, carry distributor by the Pneumatic type pipe tobacco that ventilation blower provides power that pipe tobacco is distributed to many cigarette machines simultaneously.
Background technology
Strength carry to belong to fluid carries, and it is to be working media with the air, by gas flow with mass transport to the appointed place, in other words conj.or perhaps by the technology of the air communication piping convey materials of malleation or negative pressure.The conveying of Pneumatic type pipe tobacco is a kind of feeding method in the cigarette process, and with mechanical wire feed ratio, it is little that it has floor space, and pipe tobacco and dust can not escape, advantages such as good looking appearance.
For Tobacco-feeding device in the domestic cigarette industry, technology is relatively backward mostly.
Aspect charging, domestic common employing to feed silk equipment be mould turnover feed or conveyer feed, to the wire-feeding pipe feed, feed is inhomogeneous by the rotation of the filament-feeding tray of feeding silk equipment and vibration;
Aspect wind speed control, be to adopt manual modulation valve control air quantity is installed on main return air duct, at the debugging initial stage system's total blast volume is manually adjusted, after the whole system operation, generally do not adjust, because of a wire feeder gives many cigarette machines for silk simultaneously, and same conveying distributor comprises many cigarette machines, many cigarette machines are at random to the demand and supply of pipe tobacco, if wherein one or several cigarette machines at a time stop the feed demand simultaneously, this must make the air quantity in the conveying airduct of other cigarette machine change, and causes changing of wind speed in the wire feeding pipe line, it is broken that the pipe tobacco generation is made, and influences the economic benefit of cigarette industry.And the air quantity of ventilation blower can not adjust along with the discontinuous operation of cigarette machine, causes the waste of the energy, on branch's return air duct of separate unit cigarette machine pneumatic cut-off valve only is installed, and just plays on-off action, can not realize the wind speed in the wire-feeding pipe is controlled;
Aspect dedusting, because distributor does not possess the ability that the wind speed that enters deduster is regulated, at any time the system's wind speed of opening, stop causing of cigarette machine suddenlys change, the wind speed that makes dusty gas enter deduster is also taking place to suddenly change, have a strong impact on the life-span of efficiency of dust collection and sack cleaner, and the deashing time of deduster and cleaning cycle are empirical strong by artificial setting, are difficult for the ash-removal effect that reaches good.
Summary of the invention
