Compared with prior art, the utility model has the advantage of：Beaten using the printing head support part installation of fine-tuning position
Print head, using the printhead for installing elasticity heating and automatic temperature control device additional, finely tuned when may be implemented in printing printhead and paper it
Between gap and printhead inside shower nozzle ink-jet pressure, it is convenient occur when there is type batch ink marks is rare, writing without
When the problem of the handwriting is blurred on scribbling sketch and printing paper is caused when method identification, printing or frequently changing paper, regulation in time is beaten
Print position and the pressure of head.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the printhead of adjustable pressure of the present utility model；
Fig. 2 is the zoomed-in view at A in Fig. 1；
Fig. 3 is the structural representation of the shower nozzle in the utility model；
Fig. 4 is the sectional view at B-B in Fig. 2.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Refering to shown in Fig. 1 to Fig. 4, a kind of printing of adjustable pressure, including printer stand 1, printhead 2, paper bowl 3,
Word car 4 and printer controller, printhead 2 is on word car 4, and word car 4 and paper bowl 3 are same on printer stand 1, printer
Controller is generally external computer, in addition to printing head support part 5 and support shaft 6, and the axle of word car 4 is arranged on printing head support part 5
Front end, support shaft 6 are arranged on the rear end of printing head support part 5 and on the bearings of printer stand 1, the both ends of printer stand 1
Shift fork 9 is provided with, the axle both ends of word car 4 are provided with clutch shaft bearing 7, and the axle both ends of paper bowl 3 are provided with second bearing 8, first axle
Hold 7 and the position of second bearing 8 it is corresponding and leave gap between the two, when gap does not have, representative can not adjust shift fork 9 again
Reduce the gap between paper and printhead 2, be minimum position-limiting action, a pair of chutes 112, paper are provided with printer stand 1
The axle both ends of roller 3 are located in chute 112 respectively, and chute 112 is circular arc, and the axis weight of the center of circle of circular arc and support shaft
Close so that the regulation of paper bowl 3 is more stable, and second bearing 8 is provided with step, and fork slot 82 is provided with the bearing surface of step 81, dials
Fork 9 is arranged in fork slot 82, and the end of shower nozzle 10 inside printhead 2 is additionally provided with one group of elasticity heating element heater 11.
In the present embodiment, after elastic heating element heater 11 is arranged on original first heating element heater 12 in the inside of shower nozzle 10
End, elastic heating element heater 11 have jagged telescopic joint 111, and heating is flexible, the distance between nozzle adjustable 10 and paper,
And the speed that ink flows through, end both sides are respectively arranged with distance measuring sensor 13 and pressure sensor 14, ranging on printhead 2
Sensor 13 and pressure sensor 14 electrically connect with printer controller；The front end of first heating element heater 12 is additionally provided with automatic control
