Abstract

The invention provides an intelligent control system for a glue flow rate. The intelligent control system comprises a flow rate controller, pressure transmitters, an electric proportional valve, a programmable logic controller man-machine and an interchanger. The pressure transmitters are installed on an exit and an entrance of the flow rate controller and collects an analog quantity signal to transmit to a programmable logic controller, the programmable logic controller converts the analog quantity signal into digital quantity through analogue-to-digital conversion, the digital quantity is compared with parameters set by the man-machine interchanger and subjected to PID calculation, and a calculated result is converted into analog quantity to be output to the electric proportional valve. The electric proportional valve controls the pressure of the flow rate controller to ensure the pressure of the exit and constancy of the glue flow rate. The intelligent control system for the glue flow rate can effectively eliminate the phenomenon of concentric reducers in the gluing process and ensure the constancy of the glue flow rate and is high in efficiency and capable of meeting different production requirements because glue-out speed is adjustable, and therefore product quality is ensured.

Description

A kind of glue flow intelligent control system
Technical field
The present invention relates to field of intelligent control technology, particularly a kind of glue flow intelligent control system.
Background technology
The glue flow control system has following shortcoming at present:
1, manual control system's glue mass flow discrepancy is even, efficiency is low, and exists the gluing brought because of the factors such as difference of operating personnel's technical merit inhomogeneous, can't guarantee the qualification rate of product.
2, general automatic control system is not used feedback system, can not guarantee that the glue flow is even, and the concentric reducer phenomenon easily occur in the plastic emitting process, is commonly called as dog bone.
Summary of the invention
In order to overcome the defect of existing control technology, the invention provides following technical scheme:
A kind of glue flow intelligent control system, comprise flow regulator, pressure unit, electric Proportion valve, man-machine and the switch of Programmable Logic Controller, described pressure unit is arranged on the import and export of flow controller, pressure unit collects analog signals and is transferred to Programmable Logic Controller, described Programmable Logic Controller converts this analog signals to digital quantity through AD, and carry out PID calculating with the parameter comparison of man-machine interchanger setting, and be that analog output is to electric Proportion valve by the results conversion of calculating, the pressure of described electric Proportion valve control flow controller guarantees the size of top hole pressure, thereby guarantee the constant of glue flow.
The beneficial effect that the present invention brings is: this system can effectively be eliminated the concentric reducer phenomenon produced in the gluing process, guarantees the glue constant flow, and efficiency is high and plastic emitting speed is adjustable to adapt to different Production requirements, thereby guarantees the quality of product.
 
The accompanying drawing explanation
Fig. 1 is glue flow intelligent control system figure
Number in the figure is:
1---pressure unit 2---Programmable Logic Controller
3---electric Proportion valve 4---flow regulator
5---man-machine interchanger
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
A kind of glue flow intelligent control system as shown in Figure 1, described control system replaces general automatic control with closed-loop control, and it comprises flow regulator 4, pressure unit 1, electric Proportion valve 3, Programmable Logic Controller 2 and man-machine switch 5 etc.
Flow regulator 4 is for controlling the executive component of glue uninterrupted, pressure unit 1 is for the inlet and outlet pressure of Real-Time Monitoring flow regulator 4, the data that Programmable Logic Controller 2 collects for calculation process pressure unit 1, electric Proportion valve 3 is the demonstration directly perceived for parameter setting and monitoring situation for the pressure of controlling flow regulator 4, man-machine switch 5.Wherein man-machine switch 5 is communicated by letter and is carried out exchanges data with Programmable Logic Controller 2, the analog signals that pressure unit 1 gathers is transferred to Programmable Logic Controller 2, Programmable Logic Controller 2 is that through PID, computing is converted to the analog quantity control signal by the digital quantity obtained and exports to electric Proportion valve 3 again after digital quantity signal by this analog signal conversion, and electric Proportion valve 3 is controlled flow regulator 4 in real time.Known according to Bernoulli equation: when external condition is constant, the turnover pressure differential of the flow velocity of glue and sebific duct is linear, thereby can determine plastic emitting constant airspeed when constant pressure, and can change plastic emitting speed according to changing the pressure size.The sequencing that capable of regulating flow quantity regulator 4 and glue rifle are opened is simultaneously eliminated the appearance of glue concentric reducer (dog bone).
The workflow of system is: pressure unit 1 is arranged on to the import and export of flow controller 4, pressure unit 1 collects analog signals and is transferred to Programmable Logic Controller 2, Programmable Logic Controller 2 converts this analog signals to digital quantity through AD, and carry out PID calculating with the parameter comparison that man-machine interchanger 5 arranges, by the results conversion of calculating, be that analog output is to electric Proportion valve 3, the pressure that electric Proportion valve 3 is controlled flow controller 4 guarantees the size of top hole pressure, thereby guarantees the constant of glue flow.The pressure of flow controller outlet can be set according to the speed of gluing speed to adapt to different production requirements simultaneously, realize the Based Intelligent Control of flow.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
