Twido PLC in the application of multi-function concrete block molding machine

Twido PLC controller application in multi-function concrete block molding machine He Weidong welcome to e exhibition hall 10 building materials machinery exhibition hall cement equipment, baking-free brick machine/brick making machine, block molding machine, glass production equipment, tube machine, cement. 。 。 1. Overview of multi-function concrete block molding machine is the new building materials production equipment, due to the country for the protection of land resources is increasingly strengthened, the traditional sintering machine brick has been more and more limited, and multi-functional concrete block molding machine can make use of fly ash, coal cinder, coal gangue waste and other renewable resources for a variety of building brick production, has the characteristics of green environmental protection, market demand is a trend of rising. 2. System to describe the characteristics of the multi-functional concrete block molding machine electrical control system is the technology requirement of each step change is more, with the change of the brick type, analog output of the given value multiplied, puts forward higher requirements on data capacity, procedures and interface is more complicated, the system I/O points. According to this characteristic, we chose Twido series PLC controller in the design selection, schneider electric is it in order to adapt to the control of small independent machines launched a high cost performance of compact controller. Small size, powerful functions, In the process control can be configured as many as 14 PID control loop, etc. ) 。 Multi-function concrete block molding machine electric control system of the system configuration is as follows: system by ontology TWDLCAA24DRF, DI TWDDDI32DK extension module and CPU TWDDDO16DK TWDAMO01HT composition and two analog output module, blue and white touch-screen XBTG2110 man-machine interface. Actual control cabinet wiring as: the system consists of hydraulic station, conveyor belt, send board institution, conveying mechanism, pressure head, frame, vibration platform and institutions into the brick, the other can according to customer's requirements with fabrics and fold brick body, process flow diagram is as follows: process description Twido PLC in the system not only controls the flow of interlock switch, and about the quality of the brick molding plays a vital role. System of feed, brick molding and stripping process key depends on the control of the hydraulic system of proportional valve opening to achieve, therefore, the precise control is an important guarantee of product quality. System simulation module of the output by the proportional amplifier board signal output respectively as a brick machine hydraulic proportional valve flow and pressure is given, the mechanical pressure head lifting, the lifting of the frame, skip feed and platform of vibration must be segmented flow and pressure control, every movement basic is divided into three parts, respectively for the front, middle and later period, the parameters of a work cycle call to hundred, man-machine interface through XBTG2110 set in the brick type selection mode, can easily call debugging when setting the corresponding flow, pressure and time parameter. 3. Summarizes the system features: A. Flexible Twido PLC controller memory processing, more to meet the needs of multi-function preset parameters of brick making machine control system, greatly enhance the brick molding machine functions. Can easily through the man-machine interface, therefore, setting of process parameters and the replacement of the mold to achieve hollow brick, color pavement brick, grass brick and the brick production, achieve multi-usage, can be realized easily and fabrics and the control function of the automatic folding brick. B。 Control system is the key to the accurate control of the proportional valve opening, the stable operation and Twido PLC analog module, the output precision are inseparable. The high reliability and stability of the system. C。 Control system as a whole by schneider electric products, system compatibility is good, and as a result of schneider overall integration scheme, system performance is superior to other products.
