Description

Flat-panel printer

Technical field

The present invention relates to a kind of flat-panel printer, relate in particular to the flat-panel printer of distance between the print surface that can regulate print media automatically and the printing head.

Background technology

Referring to Fig. 1; Existing flat-panel printer generally all is provided with support assembly, the spray car that support assembly generally comprises framework soleplate 9, be fixed on guide rail 6 on the framework soleplate 9, can move along guide rail 6, and this spray car includes the slide block that matches with guide rail 6; Be supported on the column 5 on the slide block; The crossbeam 4 of frame on column 5, the printing head 3 that can move along crossbeam 4, framework soleplate 9 is provided with workbench 91.Print media 1 is placed on the workbench 91, and printing head 3 is done directions X and moved on crossbeam 4, and crossbeam 4 is done the Y direction with column 5 and moved and realize printing on guide rail 6.And before printing, need crossbeam 4 is done the adjustment of Z direction on column 5, so that make the distance that keeps satisfied printing to require between the print surface of printing head 3 and print media 1, thereby guarantee printing effect.For the print media 1 of different-thickness, adopt the flat-panel printer of this structure, need print requirement to satisfy according to the relevant position of thickness adjustment crossbeam 4 on the Z direction of print media 1, this makes printing bother.

The one Chinese patent application that publication number CN101298214A, name are called " a kind of print mechanism of flat-panel printer " discloses a kind of printing mechanism; Mainly comprise spray car and printing head two parts; The spray car is made up of with the crossbeam that is connected two slides two slides; Printing head is installed on the crossbeam; Have along crossbeam move left and right and two frees degree of vertical crossbeam up-down, on spray car slide, be provided with the gearbox that is used to drive the printing head move left and right, in printing head, be provided with the elevating mechanism that drives its up-down.Printing mechanism is installed on the fixing print platform, and the spray car can vertically move along platform, and printing head can laterally move along the spray car, has realized the printing on plane.Printing head can the free adjustment height, is suitable for the product of different-thickness, has realized the printing of stereo article.If adopt artificial adjustment can cause waste man-hour to the height of printing head in this technical scheme, if adopt electric induction then can make the plant equipment complex structure through the plant equipment adjustment

Printing head in above-mentioned two kinds of technical schemes is according to the thickness adjustment height of print media; Make printing head along with adjustable height no matter be through crossbeam is done the Z direction on column adjustment; Still directly adjust the height of printing head self, the position that all is the adjustment printing head is to adapt to print media.

Summary of the invention

Main purpose of the present invention provides the flat-panel printer of distance between a kind of print surface and the printing head of automatic adjusting print media.

For realizing above-mentioned main purpose, flat-panel printer provided by the invention comprises support assembly; The spray car; Printing head and automatic spacing device.The automatic spacing device comprises the limited block that is provided with spacing point and the clamping device that cooperates with spacing point, and is spacing below the printing head and in maintenance printing distance on the short transverse and between the printing head, clamping device is positioned under the said spacing point.

Visible by such scheme; Clamping device cooperates with the spacing point of limited block, can print media be clamped on the clamping device, is keeping printing distance on the short transverse and between the printing head owing to spacing; The surface to be printed and the printing head that are print media are keeping the printing distance; No matter how the thickness of print media changes, and the distance between surface to be printed and the printing head is constant, makes that the distance between surface to be printed and the printing head meets the printing requirement; The height and position that has reached automatic adjusting print media is printed the requirement of distance to adapt to shower nozzle, has realized the purpose of distance between automatic adjusting print media and the printing head.

A concrete scheme is that clamping device comprises pressing plate and forces pressing plate to be tending towards the force-applying piece of spacing point.Force-applying piece is tending towards spacing point to the pressing plate application of force to force pressing plate, and pressing plate and limited block are clamped print media.

Scheme is more specifically, also comprises at least one guide pillar that passes pressing plate.The up-down of pressing plate is led by guide pillar, makes smooth and easy.

Scheme is more specifically, and guide pillar is set to four, and rectangular distribution, can make the pressing plate relative steady and smooth of going up and down like this.

Another more specifically scheme be that force-applying piece adopts spring.Using spring that pressing plate is exerted pressure, both to save the energy also simple in structure.

Again one more specifically scheme be that force-applying piece adopts cylinder.Use cylinder that pressing plate is exerted pressure and make the precise control of active force.

Also one more specifically scheme be that force-applying piece adopts foam sponge.Use foam sponge that pressing plate is exerted pressure, simple in structure, good and cheap.

The specific embodiment

First embodiment

Referring to Fig. 2; Flat-panel printer of the present invention is provided with support assembly; This support assembly comprises two closed slides 6 on framework soleplate 9, the framework soleplate 9 and the spray car that can move along guide rail 6, and the spray car comprises two slide blocks that match with two guide rails 6 respectively, is fixedly supported on two columns 5 on two slide blocks respectively; The crossbeam 4 of frame on two columns 5, the printing head 3 that can move along crossbeam 4.In addition, also be provided with the automatic spacing device, the automatic spacing device comprises limited block 7 and the pressing plate 2 that cooperates with the spacing point 71 of limited block 7.

Referring to Fig. 3; Guide pillar 81 vertical fixing that are with spring 8 are on framework soleplate 9; Pressing plate 2 is being pressed spring 8 to be enclosed within on the guide pillar 81 and is being placed spacing point 71 times, the upper surface that pressing plate 2 and spacing point 71 make print media 1 and printing head between keep 2 ㎜ distances the position.

Referring to Fig. 4, four guide pillar 81 rectangular distributions.

During operation,, at first pressing plate 2 is applied along the power F of the diagram direction of arrow referring to Fig. 5; Spring 8 is compressed, and it is descending to make pressing plate 2 break away from spacing point 71, then; The template that print media 1 perhaps is equipped with print media 1 is placed on the pressing plate 2, cancels the power F that acts on the pressing plate 2, under the effect of spring 8 restoring forces; Pressing plate 2 is up, contacts with spacing point 71 until the upper surface of print media 1, thereby has realized the automatic location to print media 1 surface to be printed.Description by the above course of work is visible, and regardless of the thickness of print media 1, the automatic spacing device can make the upper surface of print media 1 and the distance of printing head keep constant, has realized the purpose of distance between automatic adjusting print media and the printing head.

Second embodiment

The present embodiment and first embodiment are basic identical, referring to figure, and 6, difference is: force-applying piece is a cylinder 83.
