Description
Technical field
The utility model relates to the ink jet printing field, in particular to ink-jet printer and shower nozzle position limiting structure thereof.
Background technology
Ink-jet technology has obtained using widely at present.The jet-printing head of sprayed printed system needs to regulate in long-term the use apart from the height of stock, can be divided into two kinds of situations: the one, the high-order adjusting, when carrying out blow head maintenance, observe the nozzle situation, changing stock and sprinkler height during nonproductive state when stopping to produce is regulated, higher apart from stock, not strict to requirement for height, only need coarse adjustment just can satisfy, but need to regulate efficient and convenient; The 2nd, low level is regulated, and promptly production status is regulated, and jet-printing head, needs accurately to regulate less than 1mm apart from stock during production status.
In this field, multiple sprinkler height control method and device are arranged at present, Fig. 1 shows the schematic diagram according to the shower nozzle position limiting structure of a kind of ink-jet printer of correlation technique.This governor motion comprises: frame 3, knob 11, slide rail 12 and screw rod 8.Slide rail 12 control shower nozzle directions, screw rod 8 is realized the upper-lower position adjustment, rotation knob 11 realizes that the rising of shower nozzle 1 descends.Though manual adjustments structure dexterity, this mechanism can realize that adjustable height is limited, and is reduced to working position after raising at every turn and all needs to adjust once more, regulates slowly, and manpower and the time expended are long.Can not satisfy the demand of production.
Fig. 2 shows the schematic diagram according to the shower nozzle position limiting structure of the another kind of ink-jet printer of correlation technique.This mechanism mainly comprises, shower nozzle 1, cylinder 2, frame 3, slide rail 4, banking pin 5 and position-limited rack 11, and cylinder 2 control upper-lower positions, slide rail 4 controlling parties guarantee that to, banking pin 5 lowest orders also finely tune.This mechanism can realize the quick conversion of high-order and low level, and lift is also bigger, and the adjusting of lowest order can realize that this mechanism has only two positions by controlling banking pin 5, that is: inoperative position, highest order; Working position, lowest order.
The adjustment process of this mechanism is as follows: give cylinder 2 inflations, shower nozzle 1 rises to highest order, cylinder 2 exhausts, and shower nozzle 1 is reduced to lowest order.When changing stock, regulate 5 pairs of lowest orders of banking pin and finely tune, increase or reduce, enough little to guarantee shower nozzle 1 with the spacing on stock surface.
The inventor finds that this mechanism is poor slightly at the process stability of shower nozzle lifting, and is particularly too big in the easy velocity perturbation of the highest lowest order, causes the vibration of shower nozzle easily, thereby causes the spray printing poor stability.
