Abstract
The utility model discloses a wind volume control system of a shredded tobacco winnowing machine, which comprises a wind volume sensor, a controller and a control valve, wherein the wind volume sensor is arranged in an air duct of the shredded tobacco winnowing machine, and detects and outputs wind volume signals in the air duct; the controller is arranged in the air duct of the shredded tobacco winnowing machine, receives the wind volume signals, conducts calculation, and outputs control commands according to the predetermined control strategy; and the control valve is arranged at a suction opening in the air duct, receives the control commands transmitted by the controller, and adjusts the opening/closing per se or the opening degree, so as to enable the wind velocity to vary according to the predetermined goal. Through adjusting the wind volume in the air duct of the shredded tobacco winnowing machine, the utility model enables the wind volume in the air duct to vary according to the predetermined strategy, thereby realizing control to the wind volume in the air duct, reducing the power consumption of an exhaust blower matched with the shredded tobacco winnowing machine, making effective use of the work of the exhaust blower, and preventing the shredded tobacco from being rolled up and crashed and reducing the depletion of the shredded tobacco at the same time.
Description
Technical field
The utility model 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%.
The utility model content
The utility model purpose 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, the technical solution of the utility model 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 utility model 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 the utility model tobacco shred winnowing machine air quantity control system.
The specific embodiment
Basic design of the present utility model 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 utility model is further described.
Referring to Fig. 1, this figure is the block diagram of the utility model tobacco shred winnowing machine air quantity control system, 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.
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 utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
