Abstract

The invention provides a spray device. The spray device comprises a spray head and a cleaning module, wherein the spray head comprises a plurality of spray holes and an ink inlet pipe which are communicated together, wherein the spray holes are connected with vacuum extraction equipment; the cleaning module comprises a cleaning component provided with a cleaning tank; and the spray head sucks up a cleaning agent from the cleaning tank under the action of the vacuum extraction equipment and drives the cleaning agent to enter the spray holes so as to clean the spray head. The spray device provided by the invention has the advantages that the cleaning component and the cleaning tank are matched with the vacuum extraction equipment so as to increase the cleaning agent which reversely flows into the spray holes and reach bigger cleaning pressure, thus achieving a better cleaning effect.

Description

Spray equipment

Technical field

The present invention relates to a spray equipment, particularly a spray equipment that can clean shower nozzle automatically.

Background technology

After ink-jet printer used and cuts out a period of time, the ink around the spray orifice of residual shower nozzle will retrogradation even is become solid-stately, so it can stop up spray orifice or usually attached to the outside of nozzle and hinder and spray task executions next time.

A kind of spray equipment that carries cleaning function comprises shower nozzle and cleans module.Shower nozzle has working face, a plurality of spray orifice of this working face and ink supply pipe that links to each other with spray orifice of running through.This ink supply Guan Yuyi vacuum extractor links to each other.Clean module and comprise solvent service and the solvent recovery pipeline that is opened in shower nozzle and runs through working face.Solvent service, spray orifice and solvent recovery pipeline are from top to bottom arranged in working face.During use, solvent flows out from the solvent service, and solvent flows along the shower nozzle working face under the gravity effect, and vacuum plant vacuumizes spray orifice, thereby the solvent that will flow to spray orifice cleans shower nozzle along the reverse suction of spray orifice, and unnecessary solvent flow to the solvent recovery pipeline downwards and reclaims.

When above-mentioned spray equipment cleaning equipment cleaned shower nozzle, solvent was sprawled into film in the front of shower nozzle, by spray orifice is vacuumized solvent was sucked, and the solvent that flows into spray orifice is less, and influenced the cleaning performance of shower nozzle.

Summary of the invention

In view of above-mentioned condition, be necessary the spray equipment that provides a kind of cleaning performance preferable.

A kind of spray equipment, it comprises shower nozzle and cleaning module, shower nozzle comprise a plurality of spray orifices of being opened in shower nozzle, communicate with these a plurality of spray orifices advance the China ink pipe, spray orifice links to each other with vaccum-pumping equipment, cleaning module comprises cleaning part, cleaning part is formed with rinse bath, and the shower nozzle opposite direction that China ink flows when self-cleaning groove under the vaccum-pumping equipment effect is drawn cleaning agent and make cleaning agent along printing enters spray orifice to clean shower nozzle.

This spray equipment cooperates with vacuum extractor to make the cleaning agent of going into from the spray orifice reverse flow more by cleaning part and rinse bath are set, and can reach bigger cleaning pressure, thereby cleaning performance is preferable.

The specific embodiment

The spray equipment that also in conjunction with the accompanying drawings the embodiment of the invention is provided with the specific embodiment is described in further detail below.

See also Fig. 1 and Fig. 2, the spray equipment 100 of embodiment of the present invention comprises shower nozzle 10, vacuum tank 30, cleaning module 50 and vacuum equipment 80.Be to save length, the uncorrelated assembly with the technology of the present invention means of other of spray equipment 100 as word car, paper advance mechanism, print cartridge etc., is not mentioned in specification or is shown in icon.

See also Fig. 3 and Fig. 4, shower nozzle 10 comprises main body 12, support division 14, advances China ink pipe 16 and drain pipe 18.

See also Fig. 5, main body 12 is roughly rectangle, is formed with ink storage chamber 122 in it.Main body 12 also offers a plurality of spray orifices of linearly arranging and communicating with ink storage chamber 122 124, ink-feeding hole that communicates with ink storage chamber 122 126, a fluid hole 128 that communicates with ink storage chamber 122.In the present embodiment, ink-feeding hole 126 and fluid hole 128 are opened in relative two sides adjacent with the side that offers spray orifice 124 respectively.

Please consult Fig. 4 once more, support division 14 protrudes from the side that offers spray orifice 124, and support division 14 is formed with the rectangular hole 142 of keeping away with spray orifice 124 correspondence positions.

See also Fig. 1 and Fig. 5, advance China ink pipe 16 and be connected to main body 12 via ink-feeding hole 126, drain pipe 18 is connected to main body 12 via fluid hole 128.Advance on China ink pipe 16 and the drain pipe 18 and be respectively equipped with valve 162 and valve 182.Drain pipe 18 is connected to vacuum tank 30 away from an end of main body 12.Vacuum tank 30 links to each other with vaccum-pumping equipment 80 simultaneously.

See also Fig. 3 to Fig. 5, cleaning module 50 comprises cleaning part 52, seal 54, fixture 56, feed tube 58 and discharging tube 59.Cleaning part 52 is roughly cuboid, and the one end is formed with the storage tank 522 of the end face that runs through cleaning part 52 and the rinse bath 524 that forms from the bottom notch of storage tank 522.Cleaning part 52 other ends offer passage 526, the inlet opening 527 that is communicated with passage 526 and outage (figure is mark not).Inlet opening 527 and outage all run through cleaning part 52 surfaces.Cleaning part 52 also offers a plurality of through holes 529 of interface channel 526 and rinse bath 524.Feed tube 58 and discharging tube 59 are communicated to cleaning part 52 via inlet opening 527 and outage respectively.
