Dust exhaust and printing equipment

The utility model discloses a dust exhaust and printing equipment. This dust exhaust, first negative pressure produces the part and produces the negative pressure in order to inhale the smoke and dust to the negative pressure wind channel, transport to the second negative pressure and produce the part by transporting the pipeline again, and the second negative pressure produces the part and produces the smoke and dust that the negative pressure will transport the pipeline and discharge, has avoided the smoke and dust at wind channel and the blockage that transports the pipeline, has improved the effect of dust exhaust. 本实用新型公开了排尘装置及印花设备。该排尘装置，第负压产生部件产生负压以将烟尘吸入至负压风道，再由输运管道输运至第二负压产生部件，第二负压产生部件产生负压将输运管道的烟尘排出，避免了烟尘在风道和输运管道的阻塞，提高了排尘的效果。
