Abstract
The invention discloses an air quantity control system of a tobacco shred winnowing machine, which comprises an air quantity sensor, a controller and a control valve, wherein the air quantity sensor is arranged in an air flue of the tobacco shred winnowing machine and used for detecting and outputting air quantity signals in the air flue; the controller is arranged in the air flue of the tobacco shred winnowing machine and used for receiving the air quantity signals, performing operation and outputting control instructions according to a predetermined control strategy; and the control valve is arranged at a suction opening in the air flue and used for receiving the control instructions sent by the controller, and adjusting self opening/closing or adjusting the opening degree to change the air speed according to a predetermined target. The air quantity in the air flue is changed according to the predetermined strategy by adjusting the air quantity in the air flue of the tobacco shred winnowing machine so that the air quantity in the air flue is controlled, the power consumption of a suction fan of the tobacco shred winnowing machine is reduced, the applied work of the suction fan can be effectively utilized, and meanwhile the tobacco shreds are not rolled and do not collide to reduce the loss of the tobacco shreds.
Description
Technical field
The present invention relates to the control system of tobacco shred winnowing machine, particularly the air quantity control system of tobacco shred winnowing machine.
Background technology
In production of cigarettes, general employing tobacco shred winnowing machine is rejected foreign material and the defective work in the pipe tobacco on the throwing line.After the tobacco shreds drying operation, tobacco shred winnowing machine also can be used as to cut filler mixes the even equipment of compounding, not only makes the blending that cuts filler even, and makes the moisture in cut tobacco after being mixed more even, has improved the technology for making tobacco threds quality.But also there are the following problems on design and actual motion for tobacco shred winnowing machine at present:
1, the distribution of exhausting blast and air quantity is obviously uneven, and far away more from suction opeing, blast and air quantity are more little.In tobacco shred winnowing machine, because feeding belt is far away from suction opeing place distance, causing to provide bigger air quantity the pipe tobacco on the feeding belt could be kicked up by more powerful air exhauster, and power consumption is big.
2, owing in the air channel of tobacco shred winnowing machine, go out strip under suction opeing, this place's negative pressure and air quantity maximum are kicked up after pipe tobacco falls once more, the spin-cleaning device and the silk screen at a large amount of pipe tobaccos bump suction opeings place, and the pipe tobacco broken rate can reach 5%.
Summary of the invention
The object of the invention is, a kind of air quantity control system of tobacco shred winnowing machine is provided, the air quantity in the control air channel.
For solving above technical problem, technical scheme of the present invention is that a kind of air quantity control system of tobacco shred winnowing machine comprises:
Air flow sensor is arranged in the air channel of tobacco shred winnowing machine, detects and export the air volume signal in the air channel;
Controller is arranged in the air channel of tobacco shred winnowing machine, receives the air volume signal row operation of going forward side by side, according to predetermined control strategy output control instruction;
Control valve is arranged at suction opeing place in the air channel of tobacco shred winnowing machine, receives the control instruction that controller sends, and regulates the On/Off of self, perhaps regulates aperture, and air quantity is changed according to predeterminated target.
Preferably, described air flow sensor is a plurality of, and described controller calculates the mean value of the air volume signal of each air flow sensor detection and output, as the actual air volume in the air channel.
Preferably, also comprise input block, be used for writing the predetermined wind amount target component to described controller.
Preferably, described controller is a programmable logic controller (PLC).
Preferably, described air flow sensor is temperature-sensitive air quantity probe.
Compared with prior art, the present invention is by regulating the air quantity in the tobacco shred winnowing machine air channel, air quantity in the air channel is changed by predetermined policy, thereby reach control to air quantity in the air channel, make the power consumption of air exhauster that tobacco shred winnowing machine is joined reduce, can effectively utilize the acting of air exhauster, simultaneously, make pipe tobacco can be not rolled-up, collision, reduce the loss of pipe tobacco.
Description of drawings
Fig. 1 is the block diagram of tobacco shred winnowing machine air quantity control system of the present invention.
The specific embodiment
Basic design of the present invention is that the air quantity in the air channel of control tobacco shred winnowing machine makes the air quantity in the air channel change according to predetermined control strategy.
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1, this figure is the block diagram of tobacco shred winnowing machine air quantity control system of the present invention, comprising:
Some air flow sensors 4 are arranged in the air channel 5 of tobacco shred winnowing machine, are used to detect and export the air volume signal in the air channel 5.As a kind of preferred mode, air flow sensor 4 is temperature-sensitive air quantity probe, is particularly suitable for surveying in the pipeline wind.In addition, air flow sensor 4 is a plurality of, with each air flow sensor 4 detect and the air volume signal mean value of output as the actual air volume in the air channel 5.
Controller 3 receives each sensor signal, judges that whether actual air volume is greater than characterizing the predeterminated target air quantity of just rolling the pipe tobacco minimum wind force, if export first control signal; If not, export second control signal.Wherein, controller 3 is programmable logic controller (PLC) (PLC), the efficient height, and the environment applicability is good.
Control valve 2 is installed in suction opeing place in the air channel 5, reduces self aperture according to first control signal, reduces air output, increases self aperture according to second control signal, increases air output.
Input block 1 is used for writing predetermined wind amount control parameter to controller 3.For different pipe tobaccos, can detect pipe tobacco in advance and roll required air quantity parameter, obtain behind the target air quantity writing controller 3 again, thereby revise the control parameter of controller 3 easily.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim institute restricted portion.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
