Description

Hole plate print device

Technical field

The present invention relates to hole plate print device.

Background technology

With reference to Fig. 5～Fig. 9 existing hole plate print device is described.Generally, in hole plate print device, as shown in Figure 5, columned version tube 1 that freely rotate, vesicular structure is set, on its outer peripheral face, as shown in Figure 6 and Figure 7, volume pastes screen pack 2 is installed, and it comprises the 2b of mesh portion that the printing ink that does not see through printing ink does not see through the 2a of portion and can see through printing ink.And then on the periphery of screen pack 2, as shown in Figure 6, package through perforation, the porous body paper Ma of plate-making (to call " making master Ma " in the following text), and its leading section is supported by the clamping plate 3 of the freely openable that is provided with at the outer circumference bus along version tube 1.In addition, at Fig. 6,, represent to make master Ma with double dot dash line in order to simplify mapping.

As Fig. 8 and shown in Figure 9, version tube 1 comprises that non-aperture area 1a that does not see through printing ink and (with reference to Fig. 9 B) that forms many hole 1c can see through the aperture area 1b of printing ink.In addition, in Fig. 9 A,, represent to make master Ma with double dot dash line respectively, represent screen pack 2 with chain-dotted line in order to simplify mapping.

In the inside of version tube 1, as shown in Figure 5, ink feeder 4 is set, the printing ink that will supply with to outer peripheral face with membranaceous form when it is included in and rotates with the rotation direction A of version tube 1 is measured the ink roller 5 on the inner peripheral surface that pointwise supplies with version tube 1 in accordance with regulations.And around version tube 1, configuration press pressure roller 6 as pressing mechanism, and it is wrapped in making on the master Ma on the version tin 1 with printing P by being pressed in.

In such hole plate print device, as shown in Figure 5, regularly printing is delivered to version tube 1 and by between the pressure roller 6 from paper feed part 110, with ink roller 5 with press pressure roller 6, by version tube 1 with make master Ma etc. and push the printing P that sends, the printing ink of supply on version tube inner peripheral surface is oozed out from the 2b of mesh portion of the perforate 1c of the aperture area 1b of version tube 1 part, screen pack 2 and the perforated portion of making master Ma,, make the printing image by transfer printing on printing P.

At this, because be accompanied by the rotation of version tube 1 by pressure roller 6, aperture area 1b from the downstream side of the rotation direction A of version tube 1 to upstream side (below, rotation direction A based on version tube 1 deserves to be called stream and dirty) push version tube 1 in turn, so in press the printing ink (to call " residual ink " in the following text) that does not use to be expressed into the upstream side of aperture area 1b by aperture area 1b.The residual ink that is extruded enters the outer peripheral face of version tube 1 and the printing ink of screen pack 2 does not see through between the 2a of portion, does not finally spill through the upstream side of the 2a of portion from printing ink.Therefore, the inside of stained printing P and hole plate print device.

So, leak from version tube 1 in order to prevent printing ink, on version tube 1, shown in Fig. 8 and Fig. 9 B, be provided with by the shutoff residual ink, what prevent that printing ink from leaking prevents leakage of oil China ink parts 7, with the upper reaches end of covering aperture area 1b; Shown in Fig. 9 B, do not see through the 2a of portion at the printing ink of screen pack 2 and printing ink is set induces parts 8, its end is inserted version tube 1 and is prevented between the leakage of oil China ink parts 7, residual ink is induced into the perforate 1c of aperture area 1b.In addition, at Fig. 9 A,, omit the diagram that prevents leakage of oil China ink parts 7 for simple and clearization of mapping.

Prevent leakage of oil China ink parts 7 usefulness two sides adhesive tapes 18 bonding non-aperture area 1a that are arranged on as version tube 1 outer peripheral face, printing ink induces the bonding printing ink that is arranged on of parts 8 usefulness two sides adhesive tapes 19 through the following 2c of the 2a of portion.If be described in detail, prevent leakage of oil China ink parts 7, as Fig. 8 and shown in Figure 9, bonding with the mode mounting of the bonding plane of the two sides adhesive tape 18 that covers prominent mound shape from the outer peripheral face of version tube 1.Thus, the printing ink that is positioned at screen pack 2 do not see through the 2a of portion below the outer peripheral face of version tube 1 on, by preventing that leakage of oil China ink parts 7 and two sides adhesive tape 18 from forming slightly the opening portion 7a like bag shape.In addition, printing ink is induced parts 8, and shown in Fig. 9 B, its base end part is arranged on the following 2c that printing ink does not see through the 2a of portion with two sides adhesive tape 19 is bonding, and the opening portion 7a like the bag shape is inserted slightly in its end.Promptly to version tube 1 assembling filter net 2 time, shown in Fig. 9 B, printing ink induces the end of parts 8 to insert slightly deep inside side (right side among Fig. 9 B) like the opening portion 7a of bag shape, forms from the space 7b of downstream side continuity in the inside like the opening portion 7a of bag shape slightly.

In addition, shown in Fig. 9 B, with prevent leakage of oil China ink parts 7 relative to version tube 1 on, up to the about centre position that prevents the black parts 7 of leakage of oil aperture area 1b is being set; By pressure roller 6 when preventing leakage of oil China ink parts 7, by be used to make by pressure roller 6 freely relatively the outer peripheral face clutch of version tube 1 do not make illustrated clutch, form by pressure roller 6 and leave the outer peripheral face of version tube 1 and do not act on structure on the aperture area 1b of the version tube 1 that is positioned at the below that prevents leakage of oil parts 7 by the pressing force of pressure roller 6.

At this, prevent that the parts that leakage of oil China ink parts 7 and printing ink induce parts 8 conducts not see through printing ink from forming.Prevent that promptly leakage of oil China ink parts 7 usefulness have printing ink wellability (following claim simply " oil resistant China ink the wellability ") material that contains oil resistant China ink corrosivity etc., for example the resin formation of PETG (PET) etc.And then, prevent leakage of oil China ink parts 7 form smoothly relative two sides adhesive tape 18 by the parts of bonding plane.In addition, two sides adhesive tape 18,19 constitutes by having oil resistant China ink wellability base material and adhesive linkage, for example, base material propylene foam, adhesive linkage is a bonding agent with propylene.On the other hand, printing ink induces parts 8 usefulness to have the infiltrating material of oil resistant China ink, for example the resin of PETG (PET) etc.As using shown in the arrow K1 among Fig. 9 B, printing ink induces parts 8 to have the function that residual ink is induced into the perforate 1c of the upstream side that is positioned at aperture area 1b.

In such structure, induce the printing ink inducing action of parts 8 by printing ink, residual ink imports slightly in the opening portion 7a like the bag shape shown in arrow K1 among Fig. 9 B.At this moment because be positioned at prevent leakage of oil China ink parts 7 below the aperture area 1b of version tube 1 on do not have the pressing force of effect by pressure roller 6, printing ink can not ooze out from the inner peripheral surface side of version tube 1; And then by being detained the pressure of the printing ink of shutoff in preventing leakage of oil China ink parts 7, residual ink is recovered to the inner peripheral surface inside of version tin 1 from the aperture area 1b of the version tube 1 that is positioned at the below that prevents leakage of oil China ink parts 7.Like this, can prevent that printing ink from leaking from version tube 1.

But, because use two sides adhesive tape 19 not see through below the 2a of portion the base end part that bonding printing ink on the 2c is induced parts 8 at printing ink, so through long-term printing ink immersional wetting, can occur or printing ink induces portion 8 and printing ink not to see through the 2a of portion to lose connecting airtight property, or final printing ink induces portion 8 not see through the 2a of portion from printing ink all to peel off the problem of getting off.

In addition, even only not losing of two sides adhesive tape 19 in its a part of adhesion zone through the connecting airtight property of the 2a of portion and the connecting airtight property that printing ink is induced portion 8 for two sides adhesive tape 19 for printing ink, also can ooze out printing ink, the inside and the printed article of the stained hole plate print device of printing ink that oozes out from its place that loses connecting airtight property.

In addition, relative two sides adhesive tape 19 level and smooth that surface and the printing ink that printing ink does not see through the following 2c of the 2a of portion is induced parts 8 by bonding plane, prevent relative two sides adhesive tape 18 level and smooth of the black parts 7 of leakage of oil by bonding plane, the state of trickle concavo-convex grade takes place in the relative two sides adhesive tape 18 of the non-aperture area 1a (outer peripheral face) of version tube 1 compared by gluing of surfaces etc. easily.This is because printing ink does not see through the state of the 2a of portion with the upper reaches end of the clamping mesh 2b of portion, is adhesively fixed on the 2b of mesh portion with heat bonding adhesive tape 9a, and its outer surface carries out the cause of coating with polyurethane rubber.In addition and since the trickle convex-concave surface that such printing ink is not seen through the following 2c of the 2a of portion be processed into level and smooth surface and improve to two sides adhesive tape 19 connect airtight a lot of operation of sexual needs and quality management, so become the high reason of cost.

Here, as the material of version tube 1, use usually corrosion resistance, oil resistivity (oil resistant China ink), resilient durability etc. good, easily form outer surface, the comparatively cheap stainless steel of level and smooth version tube 1.

Thus, the connecting airtight property of version tube 1 and two sides adhesive tape 18 through the immersional wetting of long-term printing ink, can more or less change in time, but compares with the adhering state that printing ink does not see through the two sides adhesive tape 19 of the 2a of portion with induce parts 8 by printing ink, maintains a good state for a long time.Printing ink induces parts 8 and two sides adhesive tape 18,19 etc. around carrying out version tube 1 and the scheduled maintenance inspection of version tube 1 inner cleaning when reorganizing and outfit in addition, handle as the periodic replacement product, these parts connect airtight performance lowly becomes the reason that shortens the replacement cycle, and therefore expectation improves the reliability of these parts.

Summary of the invention

The purpose of this invention is to provide through long-term operative installations (hole plate print device) and also can prevent the hole plate print device of printing ink from the generation (generally being also referred to as " tail of printing ink leaks ") of the leakage of version tube.

The hole plate print device of a first aspect of the present invention, its structure filter house in package, have on version tube aperture area, that rotate freely of porous the master of having bored a hole is installed, the perforated portion of the inside printing ink of supplying with described version tube from described master oozed out, and on paper, print image.

It has: prevent leakage of oil China ink parts, it is arranged on described version tube and goes up upper reaches end with the rotation direction of the described version tube that covers described aperture area, and shutoff in press there is not the residual ink of use by described aperture area; Printing ink is induced parts, and it is arranged on described filtration wet end with having the infiltrating adhesives of oil resistant China ink with its base portion is bonding, and its end inserts described version tube and described preventing induced described residual ink between the leakage of oil China ink parts and in described aperture area.

The hole plate print device of a second aspect of the present invention, its structure filter house in package, have on version tube aperture area, that rotate freely of porous the master of having bored a hole is installed, and the printing ink of supplying with the inside of described version tin oozes out, printing image with paper from the perforated portion of described master.

It has: prevent leakage of oil China ink parts, it is arranged on described version tube and goes up upper reaches end with the rotation direction of the described version tube that covers described aperture area, and shutoff in press there is not the residual ink of use by described aperture area; Printing ink is induced parts, and itself and described screen pack form one, and its end inserts described version tube and described preventing induced described residual ink between the leakage of oil China ink parts and in described aperture area.

According to a first aspect of the invention, by with having the infiltrating adhesives of oil resistant China ink, filter house for example the printing ink of filter house do not see through the affixed printing ink of portion and induce parts, even the junction surface (Fixed Division) of inducing parts and printing ink not to see through portion to printing ink adds the mobile pressure of the residual ink of smoothing out with the fingers out to upstream side from the downstream side of the version tube rotation direction of aperture area, also can not produce because the joint portion that the immersion printing ink of residual ink induces parts and printing ink not to see through portion loses connecting airtight property, or final printing ink induces parts not see through the problem that portion peels off from printing ink.Thereby, because the residual ink of inducing parts to induce by printing ink, by self mobile pressure from being positioned at the inside that the aperture area that prevents leakage of oil China ink parts below is recovered to the version tube, so can not spill from the upstream side of filter house (for example screen pack).Thus, even use hole plate print device for a long time, can prevent that printing ink from leaking from the version tube, the result does not have stained situation of installing inner and printed article yet.

According to a second aspect of the invention, by printing ink being induced portion and filter house, for example the printing ink of filter house does not see through portion and forms one, even the printing ink portion of inducing added the residue of smoothing out with the fingers out to upstream side from the downstream side of the version tube rotation direction of aperture area mobile pressure with China ink, owing to do not exist in the boundary that printing ink induces portion and printing ink not to see through portion by bonding etc. junction surface, so when not having for example as usefulness two sides adhesive tape cross induction parts, apply ink flow in the joint portion for a long time and press, immerse the joint portion by residual ink and lose connecting airtight property, the problem that perhaps final printing ink induces portion not peel off by portion from printing ink.Thereby, since by printing ink induce residual ink that parts induce by self mobile pressure from being positioned at the inside that the aperture area that prevents leakage of oil China ink parts below is recovered to the version tube, so can not spill from the upstream side of filter house (for example screen pack).Thus, leak from the version tube even use hole plate print device can prevent printing ink for a long time, the result does not have stained situation of installing inner and printed article yet.

At this, version tube 1 is for example to wear out many hole 1c by etching method (chemical corrosion method), and formation aperture area 1b, the stainless sheet steel that will form aperture area 1b more are curled into cylindric making, and it has certain elastic recovery.At the both ends of version tube 1, for example install and fix respectively and do not make illustrated end plate with the connection securing member of bolt etc.By the rolling bearing (not illustrating) that is provided in the two end plates central portion,, rotate and supporting version tube 1 freely with the back shaft of inking pipe 24 as cylinder.In addition, the two end plates of version tube 1 has the function of non-aperture area 1a.

Inside at such version tube 1 as shown in Figure 5, is provided with ink feeder 4.The main composition of ink feeder 4 comprises: ink roller 5; Revise roller 26, it is 5 one-tenths minim gaps of ink roller therewith, be configured in abreast and ink roller 5 between to form section be that the printing ink of chock shape accumulates and locates 27; The inking pipe 24 that inking printing ink is accumulated place 27.Metal such as ink roller 5 usefulness aluminium and stainless steel or rubber etc. are made, and rotate in the rotation direction shown in Fig. 5 together by not making illustrated gear row and version tube 1.In addition, revise metals such as roller 26 usefulness iron and stainless steel and make, rotate by not making illustrated gear row counter-clockwise direction.Ink roller 5 and 26 rotations of correction roller being supported on to hang down to being located at freely not to be done on the inking pipe 24 on the illustrated printing ink side plate.

In addition, on the periphery of version tube 1, as shown in Figure 6, along the parts that are called clamping plate base portion 17 of edition bus setting of the periphery of tube 1 by axle supporting splint 3, have again, version tube 1 for example by not doing the driving of illustrated main motor, rotates at rotation direction A shown in Fig. 5 (clockwise direction) and counter-clockwise direction.

Screen pack 2, have certain elastic returning, as shown in Figure 6 and Figure 7, it comprises the 2b of mesh portion that the printing ink that does not see through printing ink does not see through the 2a of portion and can see through printing ink, has as the elastomeric structure of porous matter, function.The 2b of mesh portion of screen pack 2, be also referred to as shield, for example make, form the mesh (for example No. 300 degree are that per inch has 300 meshes) of regulation with mylar.And the 2b of mesh portion, have maintenance, diffusion printing ink, discharge the function of printing ink with extruding.The printing ink of screen pack 2 does not see through the 2a of portion, is also referred to as banded cloth, and with having the black infiltrating material of oil resistant, for example vinyl chloride (PVC) resin that is etc. is made.

Printing ink induces parts 8 usefulness to have the infiltrating material of oil resistant China ink, for example resinous laminar film formation that waits of PETG (PET).Induce the thickness of parts 8 about printing ink, from its function and assembleability aspect, 0.1mm suits to the 0.3mm degree.If the not enough 0.1mm of thickness can take place to fracture easily and wrinkle, when assembling when thickness surpasses 0.3mm, because the intensity of material is strong excessively, so printing ink induces parts 8 cause that afterbody takes place to be leaked, so the thickness between 0.1mm～0.3mm to be suitable from projection on the version tube 1.Regulation printing ink is induced the thickness of parts 8 like this, can prevent that printing ink from inducing parts 8 fractureing of taking place of the occasion of thin thickness with wrinkle etc., on the contrary, also can prevent the afterbody leakage of inducing parts 8 projection from the version tube to cause because of the thick printing ink that takes place of its thickness.

The material that hot sticky tape splicing 9 usefulness polyurethane (PVR) are is made, its have good especially be applied to connecting airtight property and the thermal bonding that printing ink does not see through the specific coatings of the poly-propylhomoserin rubber (U) on the following 2c of the 2a of portion, the printing ink that also has PETG (PET) system is induced the connecting airtight property of parts 8, thermal bonding.In addition, hot sticky tape splicing 9 also is not limited to the material of poly-propylhomoserin resin system, so long as and printing ink not see through connecting airtight property, the thermal bonding of the 2a of portion good, it is just passable to have an infiltrating material of oil resistant China ink, is that the printing ink of base portion is difficult to infiltration with the resin of polyamide system and polyester system etc. for example.Because use this hot sticky tape splicing 9, ground, the bonding well printing ink in low price ground induce portion 8 and printing ink not to see through the 2a of portion in the time of can not taking a lot of work.In addition, use hot sticky tape splicing 9 at present embodiment as having the infiltrating adhesives of oil resistant China ink, but also be not limited to such work.

Fig. 2 represents the scope of pushing 15 by the pressing force effect of pressure roller 6.This pushes scope 15, be set at and remain near the surplus white rear end of the front end of making master Ma on the clamping plate 3 printing ink from its front end and induce in the scope in the middle of the summary of base end part of parts 8, regulation does not act on by the pressing force of pressure roller 6 and is positioned at printing ink on the aperture area 1b of the version tube 1 of the below by the 2a of portion.Printing ink does not see through the end, upper reaches of the 2a of portion, by inserting a logical width that hangs up parts (not illustrating) edge version tube 1 that flows the end thereon, is fastened on the non-aperture area 1a with a plurality of bolts 16.Also be not limited thereto in addition, following method is also arranged, for example do not tangle an end of not making illustrated spring, connect the other end of this spring etc. on the connecting pin of in non-aperture area 1a, burying underground through the end, upper reaches of the 2a of portion at printing ink.In addition, printing ink does not see through the 2a of portion, flow the occasion that the end is fixed with bolt 16 thereon, has the bonding force that certain elasticity tension is installed in order to ensure opposing, and, in order to guarantee connecting airtight property chronically, to prevent that printing ink from leaking, in the end, upper reaches that sandwiches the 2b of mesh portion, affixed at the 2b of mesh portion with hot sticky tape splicing 9a etc.

At this, in order to guarantee the flatness of 2c below printing ink does not pass through the 2a of portion at least as far as possible, for example make the specific coatings of polyurethane rubber (U), promptly differently apply and smear polyurethane rubber (U) surface treatment with the 2b of mesh portion.But because make polyurethane coating on coarse mesh, how the following 2c that printing ink does not see through the 2a of portion takes place trickle concavo-convex etc. easily, make it finish the smooth surface state and need take many man-hours and quality management, thereby become the high reason of cost.

The below action of the major part of explanation embodiment 1.

In printing, as shown in Figure 5, version tube 1 gyrates at rotation direction A, and the roller 6 of being pressed is pushed at radial direction.By see through the 2b of the mesh portion diffusion of screen pack 2 by the printing ink of pushing, extruding by aperture area 1b of pressure roller 6 from the inside of version tube 1, to ooze out equably from the perforated portion of making master Ma, transfer printing is used for printing on printing P.But residual ink rotation by version tube 1 between version tube 1 and screen pack 2 is smoothed out with the fingers out upstream side from the downstream side of aperture area 1b.

Like this, arrive the residual ink of upper reaches end of the 2b of mesh portion of screen pack 2, shown in arrow K1 among Fig. 2, induce parts 8 to be induced to printing ink by printing ink and induce in the space 7b between parts 8 and the version tube 1.

At this moment, the mobile pressure of smoothing out with the fingers out the residual ink of upstream side from the downstream side of aperture area 1b is added in printing ink and does not induce on the joint portion of parts 8 through 2a of portion and printing ink, but because printing ink is induced hot sticky tape splicing 9 cakings of parts 8 usefulness 2c below printing ink does not see through the 2a of portion, so 2c and printing ink do not induce the joint portion of parts 8 to be difficult to be soaked into by residual ink below printing ink does not see through the 2a of portion, even apply ink flow chronically presses in its joint portion, can not produce its joint portion yet and lose its connecting airtight property because of immersing residual ink, or the final printing ink problem of inducing parts 8 not peel off by the 2a of portion from printing ink.

And, because the residual ink that is induced into space 7b is recovered into the inside of version tube 1 by self mobile pressure from the perforate 1c of the aperture area 1b that is positioned at the below that prevents leakage of oil China ink parts 7, so can not spill from the upstream side of screen pack 2.Thus, even hole plate print device uses for a long time, can prevent from version tube 1 yet and leak printing ink, its result can stained printed article and device inside.

At this, induce replacement cycle of parts 8 and two sides adhesive tape 18 as the printing ink of periodic replacement parts, to hole plate print device and the existing hole plate print device of embodiment 1 compare, probatio inspectionem pecuoarem.Used described material as version tube 1 and screen pack 2.In addition, do not see through the 2a of portion as printing ink, as mentioned above, use is made by the resin of vinyl chloride, be fixed in the material of the 2b of mesh portion with hot sticky tape splicing 9a caking with the state of the end, upper reaches of the clamping mesh 2b of portion, and then, used the polyurethane rubber of implementing specific coatings as the surface treatment of the following 2c that printing ink is not seen through the 2a of portion etc.As the probatio inspectionem pecuoarem result, the hole plate print device of embodiment 1 and existing hole plate print device compare, and printing ink induces the replacement cycle of parts 8 and two sides adhesive tape 18 to prolong about twice, has confirmed to improve its reliability.

(the 2nd embodiment)

With reference to Fig. 3 A and Fig. 4 A the 2nd embodiment of the present invention (to call " embodiment 2 " in the following text) is described.In addition, represent with prosign that its explanation is also omitted with the identical part of part of explanation in embodiment 1.

Shown in Fig. 3 A and Fig. 4 A, embodiment 2 and embodiment 1 compare, and the main printing ink that is not both induces the 10a of portion formation to be arranged on the printing ink of screen pack 2 integratedly through portion 10.

Printing ink induces the 10a of portion to have: the dirty end that printing ink is not seen through portion 10 is to the folding return portion 10b that is bent to form in upper reaches; Towards the rake 10c that the crooked return portion 10b of the aperture area 1b of version tube 1 forms, its crooked angle is inserted in the 7a of opening portion it easily, and induces printing ink glibly.Thus, printing ink induces the 10a of portion can induce residual ink to arrive in the perforate 1c of perforate field 1b glibly.Like this, printing ink induces the 10a of portion to be made of return portion 10b and rake 10c, does not see through portion 10 by jet forming method and printing ink and forms one.In addition, at embodiment 2, return portion 10b does not see through portion 10 with printing ink and connects airtight, and it is folding crooked that printing ink does not see through portion 10 maintenance compartment of terrains relatively.

Printing ink does not see through portion's 10 usefulness and has the infiltrating resin material of oil resistant China ink, for example vinyl chloride (PVC) the resin formation that is.And, printing ink does not see through portion 10 and embodiment 1 same end, the upper reaches occasion of not making illustrated bolting that does not see through portion 10 at printing ink, has the bonding force that certain elasticity tension is installed in order to ensure opposing, and it is in order to guarantee connecting airtight property chronically, to prevent that printing ink from leaking, affixed on the 2b of mesh portion with hot sticky tape splicing 9a etc. in the end, upper reaches that sandwiches the 2b of mesh portion.

As the thickness that printing ink is induced the 10a of portion, from its function and assembleability aspect, the thickness of about 0.1mm～0.3mm is suitable.If the not enough 0.1mm of thickness can take place to fracture easily and wrinkle, when assembling when thickness surpasses 0.3mm, because the intensity of material is strong excessively, so printing ink induces parts 10a cause that afterbody takes place to be leaked, so the thickness between 0.1mm～0.3mm to be suitable from projection on the version tube 1.Like this regulation printing ink induce parts 10a thickness, can prevent that printing ink from inducing the occasion of parts 10a at thin thickness, what take place fractureing and wrinkling etc., on the contrary, also can prevent to leak because of the afterbody that the thick printing ink that takes place of its thickness induces parts 10a projection from the version tube to cause.

In addition,,, printing ink forms one, so do not need polyurethane rubber etc. to be carried out surface treatment for the flatness of guaranteeing similar embodiment 1 because inducing 10a of portion and printing ink not to see through portion 10 at embodiment 2.Therefore,, do not resemble and induce the junction surface of parts 8 with hot sticky tape splicing 9 caking printing ink the embodiment 1,, reduced the number in man-hour that is used for these work simultaneously, can realize reducing cost so can obtain higher reliability according to embodiment 2.

At this, when to version tube 1 assembling filter net 2 time, as shown in Figure 3, prevent on the leakage of oil China ink parts 7 by making printing ink induce the rake 10c of the 10a of portion to abut against, insertion is the deep inside (right side among Fig. 3 A) of the opening portion 7a of bag shape slightly seemingly, so omiting the space 7b that the seemingly inside formation of the opening portion 7a of bag shape continues from downstream side.Thus, printing ink is induced the 10a of portion and is prevented 7 coordinations of leakage of oil China ink parts, forms to prevent to induce the 10a of portion to drain to the formation of upstream side from the residual ink that oozes out between version tube 1 and the screen pack 2 from printing ink.

The below action of the major part of explanation embodiment 2.

In printing, as shown in Figure 5, version tube 1 gyrates at rotation direction A, and the roller 6 of being pressed is pushed at radial direction.By by the pushing of pressure roller 6, the printing ink of extruding by aperture area 1b from the inside of version tube 1 sees through the 2b of the mesh portion diffusion of screen pack 2, oozes out equably from the perforated portion of making master Ma, and transfer printing is used for printing on printing P.But residual ink rotation by version tube 1 between version tube 1 and screen pack 2 is smoothed out with the fingers out upstream side from the downstream side of aperture area 1b.

Like this, the residual ink of upper reaches end of the 2b of mesh portion that arrives screen pack 2 is induced the rake 10c of the 10a of portion by printing ink shown in arrow K1 among Fig. 3 A, be induced to printing ink and induce in the rake 10c and the space 7b between the version tube 1 of the 10a of portion.

At this moment, even induce the return portion 10b of the 10a of portion to apply from the mobile pressure of the dirty residual ink of smoothing out with the fingers out to upstream side of aperture area 1b at printing ink, owing to do not see through the boundary that portion 10 and printing ink are induced the 10a of portion at printing ink, there is not junction surface by bonding grade, so can not resemble when inducing parts 8 with two sides adhesive tape 19 (with reference to Fig. 9 B) joint printing ink so now, apply ink flow for a long time presses at the junction surface, lose connecting airtight property because residual ink little by little immerses the junction surface, perhaps final printing ink induces parts 8 to peel off.And, because be induced to residual ink in the 7b of space,, be recovered to the inside of version tube 1 from the perforate 1c of the aperture area 1b that is positioned at the below that prevents leakage of oil China ink parts 7 by the mobile pressure of self, so, can not spill at the upstream side of the 2b of mesh portion of screen pack 2.Thus, even when using hole plate print device for a long time, can prevent printing ink yet and leak from version tube 1, its result does not have the situation of the inner and printed article of stained device.

(the 3rd embodiment)

With reference to Fig. 3 B, Fig. 4 A and Fig. 4 B the 3rd embodiment of the present invention (to call " embodiment 3 " in the following text) is described.In addition, the part identical with the part that has illustrated at embodiment 2 represents that with prosign its explanation is also omitted.

As shown in Fig. 3 B and Fig. 4 B, embodiment 3 and embodiment 2 compare, and difference is that return portion 11b is connected airtight at printing ink not by in the portion 11.Printing ink induces the 11a of portion to be made of return portion 11b and rake 11c, and at embodiment 3, return portion 11b connects airtight at printing ink and do not see through in the portion 11, and with adhesives affixed (not illustrating), other formation is identical with embodiment 2.In addition, as adhesives, use two sides adhesive tape and hot sticky tape splicing etc., but also be not limited to these materials.

The printing ink that printing ink does not see through portion 11 and embodiment 2 does not similarly form through portion 10.There are thickness that regulation printing ink induces the 11a of portion and the printing ink of embodiment 2 to induce that the 10a's of portion is identical again.Printing ink induces the 11a of portion to use and the printing ink of embodiment 2 induces the 10a of portion identical materials to form.

Action, the effect of the embodiment 2 that represents among action, effect and Fig. 4 A of the embodiment 3 that represents among following one side comparison diagram 4B are Yi Bian illustrate the action of the major part of embodiment 3.

Through and the same action of embodiment 2, in printing for a long time continuously, at embodiment 2, shown in Fig. 4 A, do not see through the return portion 10b of portion 10 at the printing ink of screen pack 2, be detained a seldom part by the printing ink (as the part of representing with dot pattern) smoothed out with the fingers out by pressure roller 6, form the printing ink portion 12 that is detained, finally the printing ink of making master Ma and screen pack 2 not by portion 10 above between have on a small quantity and ooze out.At this moment, at embodiment 2, because return portion 10b does not connect airtight, so printing ink does not see through all thickness t of portion 10 ₁Thicker, so relatively the printing ink of volume is trapped in the downstream side that printing ink does not see through portion 10.

Relative therewith, at embodiment 3, as shown in Fig. 4 B, because do not connect airtight return portion 11b at printing ink, so this printing ink does not see through all thickness t of portion 11 by portion 11 with the adhesives of two sides adhesive tape or hot sticky tape splicing (not illustrating) etc. ₂Do not see through all thickness t of portion 10 than the printing ink of embodiment 2 ₁Little (t ₂＜t ₁).Thus, because the volume of the printing ink delay portion 12 also volume than the printing ink delay portion 12 of embodiment 2 is little, so can prevent from fully between the printing ink of making master Ma and screen pack 2 does not see through above the portion 11, not ooze out spilling of printing ink on a small quantity, and can obtain the effect identical with embodiment 2.

In addition, by long-term printing each time by the stress of pushing repeatedly (load) of pressure roller 6, the connecting airtight property of return portion 11b is little by little undermined, its DeGrain, even but its connecting airtight property loses fully, the state with embodiment 2 is identical only, does not have overslaugh on actual print.

Also have, at each embodiment, the hole plate print device that the present invention is suitable for is not limited to the one-piece type digital device of sensible heat of Plate making printing as shown in Figure 5.So long as on the version tube, make the printing equipment that master Ma supplies with the printing ink type from version tube inside.For example, perhaps can both be suitable on all hole plate print devices such as two sides hole plate print device at the hole plate print device and the stencil printing device of the special use of A4 version.

In addition, at each embodiment, the 2b of mesh portion is made of resin, but also is not limited thereto, and for example also can make with well-known metal.

In addition, at each embodiment, printing ink does not see through the 2a of portion, the 10th, in the affixed formation of the 2b of mesh portion of screen pack 2, but is not limited to so yet, for example can form one with the 2b of mesh portion by jet forming method and extrusion molding method etc. yet.
