Description
Technical field
The utility model relates to print field, adjusts structure in particular to ink-jet printer and shower nozzle thereof.
Background technology
Ink-jet technology has obtained using widely at present.Be subject to the lower DPI of single shower nozzle, in order to reach meticulous spray printing effect attractive in appearance, shower nozzle all adopts " army's nose angle " to arrange at present.So-called army nose angle, promptly shower nozzle is not the direction of walking about perpendicular to stock, but with the stock direction of motion acute angle angle is arranged, and the time of controlling each nozzle ink jet is to guarantee that each nozzle spray printing is on same straight line.This method is very strict to the requirement of army's nose angle.As shown in Figure 1, DPI
ABe original DPI, DPI
BFor reality is printed DPI.
DPI
B＝n×25.6/L1＝n×25.6/(L×tan(π/2-a))＝DPI
A×tan(π/2-a)
Wherein, n is the spray nozzle number; L1 is the spray printing width of shower nozzle behind the employing army nose angle; L is the original spray printing width of shower nozzle; A is the angle between shower nozzle and the Print direction.
Because it is angle a is an acute angle,, bigger but actual printing DPI is influenced by angle so the actual DPI that prints can be higher than original DPI.Can't be printed as straight line than big or little all can causing of a value, and less angular deviation will cause spray printing quality and product reduction mutually, thus need accurately regulate this angle, to guarantee to realize the expection printing precision.When a angle during less than theoretical value, theoretical DPI is less than normal, and when a angle during greater than theoretical value, theoretical DPI is bigger than normal.By the DPI size that projection on the specimen page is come out, can judge the direction and the size of angular deviation, and then direction is regulated in decision.
Do not have the higher adjustment structure of ratio of precision at present, the main mode of adjusting frame or increase pad on installing plate that still relies on realizes adjusting to this angle.Fig. 2 shows the schematic diagram of regulating DPI according to the mode of the dependence moving frame of correlation technique, and shower nozzle 20 is fixed together with frame 11, and middle without any adjustment structure, the setting angle of the DPI of shower nozzle and frame 11 is consistent.At first by printing specimen page viewing angle bias direction, when angle has deviation, by regulating the size that DPI is regulated in the installation site of frame 11 on wallboard 14.
When not needing accurate DPI, this method can satisfy the demands, and cost is lower.Along with the development of present ink-jet technology, original DPI and actual DPI increasing, adopt not only time and effort consuming of this mode, and can't satisfy the requirement of printing.When on a frame, a plurality of printhead being arranged, also bring the inconsistent problem of shower nozzle anterior and posterior height easily in the process that frame is regulated.
The utility model content
The utility model aims to provide a kind of ink-jet printer and shower nozzle thereof and adjusts structure, to solve the problem that correlation technique is not easy to regulate the angle of shower nozzle.
In embodiment of the present utility model, provide a kind of shower nozzle to adjust structure, comprising: fixed head cooperates to be installed on the frame of ink-jet printer; Installing plate cooperates the shower nozzle that ink-jet printer is installed; Governor motion, it is connected and fixed plate and installing plate, and the fit adjustment installing plate is with respect to the angle that horizontally rotates of fixed head.
In embodiment of the present utility model, a kind of ink-jet printer is provided, comprise that the shower nozzle of shower nozzle and the foregoing description is adjusted structure.
Ink-jet printer of the utility model the foregoing description and shower nozzle thereof are adjusted structure because adopt installing plate to fix shower nozzle, so overcome the problem that correlation technique is not easy to regulate the angle of shower nozzle, reached adjusting operation that makes things convenient for shower nozzle and the effect that improves print quality.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 shows the schematic diagram of army's nose angle of ink-jet printer;
Fig. 2 shows the schematic diagram of regulating DPI according to the mode of the dependence moving frame of correlation technique;
Fig. 3 shows the schematic diagram of adjusting structure according to the shower nozzle of the utility model embodiment.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Fig. 3 shows the schematic diagram of adjusting structure according to the shower nozzle of the utility model embodiment, comprising: fixed head 1, cooperate to be installed on the frame 11 of ink-jet printer, and itself and position of platform immobilize; Installing plate 2 cooperates the shower nozzle 20 that ink-jet printer is installed; Governor motion, it is connected and fixed plate 1 and installing plate 2, and fit adjustment installing plate 2 is with respect to the angle that horizontally rotates of fixed head 1.
Correlation technique is by regulating the angle that frame is regulated shower nozzle, time and effort consuming.Among this embodiment, by installing plate shower nozzle is installed in the ink-jet printer, shower nozzle is installed on the installing plate, and nozzle angle and installing plate angle are consistent, and nozzle angle changes equally when the installing plate angle changes.By being set, special governor motion rotates the angle that installing plate can be regulated shower nozzle, so it is very simple to regulate operation.
In addition, when correlation technique has a plurality of printhead on a frame, also bring the inconsistent problem of shower nozzle anterior and posterior height easily in the process that frame is regulated.And in the present embodiment, can shower nozzle be installed independently respectively by each installing plate, regulate the rotation of each installing plate respectively independently by the governor motion of each installing plate, thereby can regulate the angle of each shower nozzle respectively, so solved the inconsistent problem of shower nozzle anterior and posterior height, this has improved the quality of printing.
As shown in Figure 3, adjustment structure comprises: lower connecting block 5 and last contiguous block 6 are connected and fixed plate 1 and installing plate 2 from two ends up and down; Pivotal parts vertically passes lower connecting block 5 and last contiguous block 6, cooperates horizontally rotating of installing plate 2.
