Wherein, for the fluid infusion of workpiece local surfaces, can also be by PLC controls single-nozzle The mode of the signal break-make of corresponding electromagnetic valve is realized.
For the spray method of above-mentioned flusher 100, one is provided gypsum mold to be carried out purge, at moisturizing and ink-jet The specific embodiment of reason process is for reference:
First, choose each lateral dimension and be 1000mm × 500mm, the gypsum mold 200 of weight 100kg.By gypsum mold 200 centers being positioned at support platform 100, cantilever 130 are returned to the zero position of servomotor 150.
Start jet program on programmable logic controller (PLC) 160, servomotor 150 drives cantilever 130, along guide rail 140 Uniform motion one week, now, programmable logic controller (PLC) 160 starts gas-liquid pipeline switch, and nozzle 131 sprays compressed air, and Gypsum mold 200 is purged totally.
Secondly, above-mentioned gypsum mold 200 is divided into four subregions: the long 250mm of each subregion, weight 25kg, and needs after water spray Mould moisture is brought up to 12.5%.
Using moisture determination instrument measure each subregion of gypsum mold 200 moisture content, respectively 8%, 11%, 12%, 7%.
Adjusting dosing pump 171 makes the numerical value shown by flow meter 173 to be 100ml/s.
Above-mentioned moisture content parameter is inputted after the user interface on programmable logic controller (PLC) 160, Programmable logical controller Device 160 carries out the difference that automatic calculation process obtains between each subregion moisture content and ideal value (12.5%) and is respectively 4.5%, 1.5%, 0.5%, 5.5%, obtaining each subregion also needs to add the water yield to be 1125ml, 375ml, 125ml, 1375ml.By default gas or liquid Body flow value 100ml/s inputs to programmable logic controller (PLC) 160, and programmable logic controller (PLC) 160 calculation process obtains respectively Subregion adds water the time for 11.25s, 3.75s, 1.25s, 13.75s, and then determines the speed of service on each subregion for the cantilever 130.
Program of spraying water is started on programmable logic controller (PLC) 160, programmable logic controller (PLC) 160 controls servomotor 150 Output control pulse, controls cantilever 130 in each subregion respectively with 22.22mm/s, 66.67mm/s, 200mm/s, 18.18mm/s's Speed is run.
Now, programmable logic controller (PLC) 160 starts gas-liquid pipeline switch, starts moisturizing program, and moisture is accurate Add on the surface of each subregion of gypsum mold 200.
Finally, start ink-jet program on programmable logic controller (PLC) 160, servomotor 150 drives cantilever 130, along leading Rail 140 at the uniform velocity surround movement one week again, completes the inkjet process operation of gypsum mold 200.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for those of ordinary skill in the art For, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the guarantor of the present invention Shield scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
