Preferably, an adjusting bolt (not shown) may be further disposed at the bottom of the limiting opening 1511 and the limiting opening 1521, and the adjusting bolt may be adjusted according to the descending height requirement of the actual lifting plate 12, so as to ensure that the lifting plate 12 can descend to a preset height.

Optionally, in an embodiment, an adjusting bolt (not shown) may be disposed at the top of the limiting opening 1511 and the limiting opening 1521, and the adjusting bolt may be adjusted according to the requirement of the lifting height of the lifting plate 12, so as to ensure that the lifting plate 12 can be lifted to a preset height.

The embodiment of the utility model provides an in, in the decline in-process of elevating system 13 drive lifter plate 12, when blockking piece 122 and blockking piece 123 respectively with spacing opening 1511 and spacing opening 1521's bottom contact, lifter plate 12 has descended the within range of predetermineeing the height this moment. The elastic element 134 disposed in the lifting mechanism 13 can contract the elastic element 134 when the driving element 131 is driven by the inertia to push down the first buffer 133, so as to achieve the purpose of buffering and avoid the excessive descending of the lifting plate 12. And the contracted elastic element 134 can apply elastic downward pressure to the second buffer element 135, so as to press the stop block 122 and the stop block 123 arranged on the lifting plate 12 to the bottoms of the limit opening 1511 and the limit opening 1521 respectively and tightly attach to the bottoms, and the lifting plate 12 can be effectively lowered to a preset height, for example, the distance between an ink jet head and a paper material belt in an ink jet printing module fixed by the lifting plate 12 is kept between 0.5mm and 1mm, thereby ensuring the quality of ink jet printing.

In the embodiment of the present invention, with reference to the embodiment shown in fig. 1 to 10, in an embodiment of the present invention, an embodiment of a jet printing apparatus, the jet printing apparatus may include:

the lifting device 100 in the embodiment shown in fig. 1 to 10 and the inkjet printing module connected to the lifting device 100 are mounted on the inkjet printing module mounting part 121 of the lifting plate 12, and can be used for inkjet printing.

The specific structure and the beneficial effects of the jet printing device can be seen in the embodiments shown in fig. 1 to 10, which are not described herein again.
