Description

Technical Field

[0001] The invention relates to the technical field of inkjet printing equipment accessories, in particular to a four-head ink stack tooling. Background Art

[0002] Inkjet printing equipment is usually equipped with a printing carriage and an ink stack. Print nozzles are arranged at the bottom of the printing carriage. The ink stack is equipped with an ink suction box; the number of the ink suction boxes is equal to that of the print nozzles, and the positions are corresponding. Before the inkjet printing equipment leaves the factory, the worker needs to adjust the position of the ink suction box and the ink stack origin of the printing carriage to ensure that after the printing carriage moves above the ink stack, the ink stack can vertically lift the ink suction box and snap on the nozzle of the print nozzle to protect the nozzle. The first step of the adjustment process is to adjust the ink stack origin of the printing carriage to ensure that the printing carriage is just above the ink stack when it arrives at the ink stack origin; the second step of the adjustment process is to adjust the position of the ink suction box one by one; after each adjustment of the ink suction box, the worker needs to vertically lift the ink suction box to perform an ink extraction test to verify whether each ink suction box is adjusted in place. The more ink suction boxes there are, the more difficult it is for the worker to adjust, the longer the adjustment time is, and there is a risk that the edge of the ink suction box will damage the nozzle. The pre-delivery adjustment of the ink suction box of the existing inkjet printing equipment is both time-consuming and labor-intensive, and there is also a risk of nozzle damage.
