Abstract

The invention discloses a digital blueprint machine, which uses multiple sets of horizontal ink jet heads for blueprint and word processing and can print images and words on general paper directly. A paper roll (1) in a paper supply device is driven by a paper rubbing wheel (2) and is conveyed to a printer (5) through a cutting knife (3), the ink jet heads (6) move horizontally and are controlled by a computer to jet ink dots to paper surface, and the dot matrixes of the ink dots form the images and words. The digital blueprint machine has the beneficial effects that: 1, the images and words are clear along with long storage period, and completely comply with requirement of long storing files. 2, usage cost is low. 3, equipment reliability is high. 4, large batch printing can be realized. 5, the operation of directly generating blueprints and words from the computer is achieved. 6, large amounts of energy sources and electric energy can be saved. 7, any pollutant will not be caused.

Description

Digital blueprint machine

Technical field

The present invention relates to a kind of digital blueprint machine.

Background technology

Existing drawing is generally generated by three kinds of methods:

A kind of is through static e-file to be imprinted on the blank sheet of paper; Such as laser printer; Its operation principle is following: recording member (for example photosensitive drums) is rotated in principal direction, the laser beam of the scanning means control of printhead with the auxiliary direction of principal direction quadrature on rectilinear motion.The picture signal of handling through digital technology is input to laser modulator, and the laser beam after the modulation carries out scan exposure to the photosensitive drums of having charged, on photosensitive drums, produces electrostatic latent image, after ink powder develops, is electrostatically transferred on the blank sheet of paper again.

The shortcoming of this method is: machinery is complicated, and the photosensitive drums life-span is short, and cost is high; The ozone that high-voltage charging produces has pollution to environment.

Another kind method is to cover the translucent base map that is printed on image on the blue printing paper to make public, and forms the blueline picture through developing.The advantage of this method is that machinery is simple, and cost is low.Shortcoming is to produce base map with first method.

The third mode is to adopt single printing ink gun, and the advantage of this method is that machinery is simple, and cost is low.Shortcoming is that speed is slow.

Summary of the invention

The purpose of this invention is to provide a kind of imaging device, this imaging device can make the e-file in the computer directly be created on the common paper.

E-file in the computer is directly controlled ink gun group (6) through interface driving circuit; Ink gun group (6) is made up of monochrome ink gun group (11) and encryption ink gun (12); Wherein single ink gun (23) is installed on the workbench through liner plate (22) and substrate (21), sees Fig. 1 Fig. 2.Electric Machine Control ink gun group (6) moves in the horizontal direction; Along with moving and work of ink gun; Image and literal print or are printed on the surface of paper line by line; After ink gun group (6) completion delegation's printing or printing, transmission mechanism drives the length (line-spacing) that moves an ink gun group width on the paper vertical direction, prints so line by line or print to obtain drawing.Its helpfulness is: directly on common paper, print or printing generation drawing without intermediate, reduced use cost thereby cancelled intermediate, and do not have any pollutant generation.Owing to adopted a plurality of ink guns to work simultaneously, solved the technical problem that the ink gun group is worked simultaneously simultaneously, so the speed that the present invention produces drawing will improve greatly.

Description of drawings

From embodiment of the present invention and combine accompanying drawing will understand above and other objects of the present invention, feature and advantage more, wherein:

Fig. 1 is the vertical view of laterally many group ink guns

The cutaway view that Fig. 2 installs for ink gun

Fig. 3 is cellular glass table top and negative pressure bellows cutaway view

Fig. 4 is this device schematic side view

The specific embodiment

Paper roll in the feeder (1) receives driving wheel (2) control action, and paper is sent in the printer (5) through cutting knife (3).Paper (32) is sent on the porous glass plate (33) of printer, and is as shown in Figure 3, brush DC blower fan (34) work; Make negative pressure box (31) produce negative pressure, paper (32) is attracted on the porous glass plate (33), and ink gun group this moment (6) laterally moves; The ink dot of ink gun ejection prints on the paper (32), and after the printing delegation, blower fan (34) quits work; Drive unit makes the move forward length (print line apart from) of a printhead width of paper, blower fan (34) work, absorption paper; Ink gun is printed delegation once more, prints so line by line and obtains drawing.

What be worth proposition is:

Design is different with other between feeder of the present invention and the printing equipment; Between feeder and printing equipment, designed a tenesmus paper buffering area; Feeder also will be accepted the wide and paper length signal of paper when accepting the paper supply commencing signal; Feeder is selected suitable paper roll automatically according to the paper bandwidth signals; To print needed paper according to commencing signal and send into printing equipment and cut off automatically, because the average speed of feeder is greater than the average speed of printing, so paper is retained in (4) between feeder and the printing equipment in the length that both difference produces with dropping naturally according to the paper length signal.

Claims

1. digital blueprint machine is characterized in that: the designed image that computer produces is processed the back and directly triggers the horizontal ink guns of many groups with signal of telecommunication mode, ink gun directly with computer picture and text printout on the surface of paper, the generation drawing, said device comprises:

Connect with computer, receive and handle the interface control unit of e-file;

Receive many groups of horizontal ink guns of interface arrangement control;

The mechanism that receives interface arrangement control to transmit paper;

Lazy-tongs between paper advance mechanism and the horizontal ink gun of many groups, wherein:

Transmit the direction of paper and the direction quadrature of the horizontal ink gun of many groups.

2. digital blueprint machine as claimed in claim 1; Wherein, make and printing or printing outside normal figure and the literal and can also realize false proof purpose at specific position with special color antiforge figure or seal at the encryption ink gun of a plurality of horizontal monochrome ink guns with a printing of other increase special color; In practical application; Monochrome ink gun can be a plurality of, and concrete quantity is only got final product with one but encrypt ink gun by the design print speed decision of machine.

3. digital blueprint machine as claimed in claim 1, wherein the ink gun fixed base plate adopts double-layer plate, and the position, hole of liner plate+substrate has determined the X of ink gun, the Y location dimension, the thickness of liner plate+substrate has determined ink gun and substrate bottom surface location dimension.
