Description
Technical field
The utility model relates to a kind of drip irrigation zone device for automatically control thickness, belongs to agricultural water-saving irrigation material production equipment technical field.
Background technology
At present, the domestic drip irrigation zone production equipment generally used is " single-blade formula labyrinth drip irrigating belt unit ", its course of work is as shown in Figure 1: under the dragging of feed motor, raw material through screw(-type) feeder, by heater, liquid charging stock is sent into filter and enters head, liquid charging stock defines cylindrical shape drip irrigation zone stock after head, by sending into winder rolling after briquetting roller die mould, cutting under the traction of hauling machine, after reaching predetermined length, taking off and waiting for warehouse-in after the assay was approved.Qualified finished product drip irrigation must control within the parameter of regulation with many index, and wherein the thickness of tube wall is exactly an important indicator.The important factor affecting this index has: 1, the hauling speed of hauling machine: when batcher motor speed is constant, and the thickness of the fast drip irrigation zone of hauling speed is just thin, and the thickness of the slow drip irrigation zone of hauling speed is just thick.2, the motor speed of batcher: when the hauling speed of hauling machine is constant, the motor speed of batcher is high, and the thickness of drip irrigation zone is just thick, and the motor speed of batcher is low, and the thickness of drip irrigation zone is just thin.3, the filtration resistance of filter: because the difference of material quality, the fluctuation of heating-up temperature all can have influence on filtration resistance, the direct flowing velocity affecting liquid, when the hauling speed of hauling machine and the motor speed of batcher constant, the thickness of the large drip irrigation zone of filtration resistance is just thin, otherwise the thickness of drip irrigation zone is just thick.Filtration resistance is also relevant with life cycle, and cycle long filtration resistance is just large.In production reality, the thickness of drip irrigation zone is very rambunctious, needs operating personnel's on-line measurement at any time and adjustment, and labour intensity and stress are all very large, and product quality is also very unstable.
Summary of the invention
The shortcoming of drip irrigation zone wall thickness effectively can not be controlled in order to overcome existing drip irrigation zone production equipment, the utility model provides a kind of drip irrigation zone device for automatically control thickness, it utilizes automatic control technology to control the wall thickness of drip irrigation zone, stabilized product quality, reduces labour intensity and the stress of operator.
The technical solution of the utility model is as follows:
A kind of drip irrigation zone device for automatically control thickness, comprise thickness transducer and controller, thickness transducer and controller are arranged between hauling machine and winder, described controller comprises Switching Power Supply, analog-digital converter, PLC, analog module, touch-screen, thickness transducer is connected with analog-digital converter, analog-digital converter is connected with PLC by the input of PLC, the both positive and negative polarity of touch-screen is connected with the both positive and negative polarity of PLC, PLC is connected with analog module through winding displacement, analog module connects the main fast frequency instruction port of frequency converter (three) through output, frequency converter (three) be connected with feed motor.
A kind of drip irrigation zone production equipment, comprise feed motor, screw feeder, heater, filter, head, micro irrigation pipe embryo, briquetting roller, hauling machine, winder, it is characterized in that: drip irrigation zone device for automatically control thickness is set between hauling machine and winder.
The utility model has the advantage of: the application of drip irrigation zone device for automatically control thickness not only increases the automaticity of equipment, eliminate human factor to quality influence, ensure that product quality, but also reduce labour intensity and the skill set requirements of operator, larger economic benefit and social benefit can be produced.

Detailed description of the invention
A kind of labyrinth type drip tape production equipment, be included between hauling machine 8 and winder 9 and add thickness transducer 10 and controller 11, analog-digital converter in the output connection control device 11 of thickness transducer 10, described controller 11 comprises Switching Power Supply, analog-digital converter, PLC, analog module, touch-screen.Thickness transducer 10 is connected with analog-digital converter, analog-digital converter is connected with PLC by input X0, X1 of PLC, both positive and negative polarity A+, B-of touch-screen are connected with PLC both positive and negative polarity A+, B-, PLC is connected with analog module through winding displacement, analog module connects the main fast frequency instruction port of frequency converter (three) through output terminals A Q01, AQ0G end, and frequency converter (three) be connected with feed motor 1.
The analog signal that thickness transducer 10 sends according to the thickness of drip irrigation zone is converted to through analog-digital converter input X0, X1 of sending into PLC after data signal, both positive and negative polarity A+, B-of touch-screen are connected with both positive and negative polarity A+, B-of PLC, the thickness parameter of drip irrigation zone is set by touch-screen, real-time display numerical value, the thickness of convenient adjustment and stable drip irrigation zone.The drip irrigation zone thickness measurement signal parameter that PLC inputs according to input X0, X1 and the thickness signal parameter that touch-screen is arranged compare, the data signal sent after computing passes to analog module through communication interface winding displacement, analog signal after conversion passes to the main fast frequency instruction port of the frequency converter (three) of drip irrigation zone unit through output terminals A Q01, AQ0G, frequency converter (three) is according to main fast frequency command signal, adjustment operating frequency, change the rotating speed of feed motor 1, realize the object of drip irrigation zone gauge automatic control.Drip irrigation zone is passed through from thickness transducer, and the thickness measurement signal of generation converts by controller the control end that control signal sends into the frequency converter (three) of feed motor 1 to.When the thickness of drip irrigation zone increases, the signal strength signal intensity of thickness transducer 10 increases, and the control signal that controller sends reduces, and the output frequency of frequency converter (three) declines, and feed motor 1 rotating speed reduces, the lower thickness of drip irrigation zone; When the thickness of drip irrigation zone reduces, the signal strength signal intensity of thickness transducer 10 reduces, and the control signal that controller sends strengthens, and the output frequency of frequency converter (three) improves, and feed motor 1 rotating speed increases, and the thickness of drip irrigation zone is thickening.
