Specific embodiment
By describing technology contents of the invention, structural features in detail, realizing purpose and effect, below in conjunction with embodiment
And coordinate accompanying drawing to be explained in detail.
Illustrate that the 3D increasing material printing machines of this case indication are referred to first increasing material manufacturing is reached by innovating existing silk screen printing
Plant equipment, 3D increases material printing machine includes frame, running gear, printing mechanism and control device, and its printing general procedure is machine
Printing equipment is transported to the printing side of putting on by running gear by frame, and printing mark is often cloth textile and shoes fabric, in printing
Target web surface printed patterns, then remove printing mechanism, are dried with drying plant afterwards, further according to needs in figure after drying
Printed above case again, then printed again；Thickness until realizing the increasing material manufacturing for setting.
The 3D of this case indication increases material printing machine to be included controlling frame, running gear, printing mechanism and control device；Its work is former
Managing and running gear being provided with for the frame, the running gear includes and the road wheel of guide rail, detent mechanism and servo
Motor, frame are walked by road wheel under the drive of servomotor, and alignment system adopts two step positioning modes, realize that 3D increases material print
Flower machine positioning, carries out stamp preparation, i.e., the quick positioning that coarse positioning and fine positioning are implemented in combination with is provided with two sensings in frame
Device, first frame are walked under the drive of servomotor, after first sensor detects the positioning target for presetting, positioning
It can be locating dowel to mark, servomotor slow down, the servomotor stop motion when second sensor detects positioning target, machine
