The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Referring to Fig. 1, three-dimensional printing equipment 1 comprises base plate 11 and the molding seat 12 that is arranged on the base plate.Be extended with 4 screw rods 13 straight up from base plate 11, framework 14 is set on the screw rod 13, and can do straight-line feed along the Z direction along screw rod 13.Further be provided with guide rod 15 on the framework 14, guide rod 15 can be done straight-line feed in framework 14 upper edge Y-directions.Printhead 16 is set on the guide rod 15, and can do straight-line feed along directions X.By the control of three-dimensional printing equipment 1, printhead 16 all can be realized feeding on X, Y, the last direction of Z, and then realizes the three-dimensional printing of expection.
Referring to Fig. 2 and Fig. 3, printhead 16 has four storage cavitys (161,162,163,164), accommodates printed material black, red, yellow, Lan Si kind color in the storage cavity (41,42,43,44) respectively.Printhead further is provided with a cleaning fluid cavity volume 165, accommodates cleaning fluid in the cleaning fluid cavity volume 165, and the concrete effect of cleaning fluid cavity volume 165 is follow-up will to be further described.
Referring to Fig. 4, printhead 16 comprises that further batching chamber 166, the cleaning chambers 167 adjacent with these batching chamber 166 1 ends reach the waste chamber 168 adjacent with batching chamber 166 opposite sides, and the sidewall bottom of waste chamber 168 is provided with through hole 200.Storage cavity (161,162,163,164) and between the batching chamber 166 be provided with communication passage (invisible among the figure), communication passage is provided with valve module (invisible among the figure), and this valve module is by PRN device 1 control opened/closed, thereby realize storage cavity (161,162,163,164) with the batching chamber 166 between selectable the connection.The downstream in batching chamber 166 is provided with nozzle 169, and nozzle 169 is by playing PRN device 1 control, with the jet printing material.Batching is provided with switch module in the chamber, and this switch module comprises rotatable first plate 21, the adjacent sidewalls of described first plate 21 and waste chamber 168, and 21 are provided with through hole 211 on described first plate.Switch module comprises that further first end of second plate 22, mandrel 23 and spring 24. described mandrels 23 slidably is fixed in the center of described first plate 21, and described second plate 22 is set on the mandrel 21.Described spring 24 is arranged between first plate 21 and second plate 22, and spring 24 can receive the driving signal of PRN device 1 and rotate.
During work, the through hole 211 on first plate 21 is in the state that staggers with the through hole of waste chamber 168 sidewalls, and second plate 22 is subjected to the elastic force of spring 24 and the sidewall of cleaning chambers 167 fits tightly.Batching chamber 166 is handled the state that disconnects with waste chamber 168, batching chamber 166 with cleaning chambers 167.After PRN device 1 sends print command, open one or more storage cavity (161,162,163,164) and be communicated with batching chamber 166, printed material is entered in the batching chamber 166.PRN device 1 driving spring 24 simultaneously rotates to stir printed material.In the process that stirs, PRN device 1 further applies high temperature to batching chamber 166, makes printed material liquefaction.After the printed material in the batching chamber 166 reached the standard of injection, PRN device 1 further control nozzle 169 formed printout with the printed material ejection behind the printed material cooling curing that ejects.
Referring to Fig. 5, after print job was finished, after first plate 21 was subjected to PRN device 1 to drive rotation, through hole 211 was in state side by side with the through hole 200 of waste chamber 168 sidewalls.Cleaning fluid in the cleaning fluid cavity volume 165 is pressed in the cleaning chambers 167.Second plate 22 is slided to first plate 21 along mandrel 23 by the pressure of cleaning fluid.In second plate, 22 sliding processes, remaining printed material enters in the waste chamber 168 in the batching chamber 166.Simultaneously, in second plate, 22 sliding processes, cleaning fluid flows into batching chamber 166 and cleans the printed material that remains in the batching chamber 166, and the liquid after the cleaning is also discharged via nozzle 169.When batching after chamber 166 cleans up, 21 rotations of first plate are to position shown in Figure 4, disconnect between batching chamber 166 and the waste chamber 168 being communicated with.Second plate 22 is subjected to the screen resilience effect of spring 24 to slide into position shown in Figure 4, disconnects between batching chamber 166 and the cleaning chambers 167 being communicated with.New printed material flows in the batching chamber 166 again, and repeats aforementioned activities, until finally finishing of printing.Printed material in the waste chamber 168 can carry back storage cavity (161,162,163,164) to print again by recovery holes 300, thereby reduces cost, the protection environment.
Printhead of the present invention not only can print black, the product of red, yellow, green four kinds of colors, can also be as required, the control PRN device makes two kinds or more of colors wherein mix in batching chamber 166 in specific ratio, thereby prints the product of various colors.
