The gas of an air pressure is constituted when atmospheric pressure is to be measured under conditions of normal temperature and an air pressure
Pressure.
As long as pressure adjustment hole 154 is in a part for damped part 15.Such as, when
So can also be arranged at the side of damped part 15.Pressure adjustment hole shown in present embodiment
Although 154 faces with flexible membrane 152 opposite side being formed at damping framework 151, but it also is able to
It is arranged at flexible membrane 152.But, by pressure adjustment hole 154 being arranged at damping framework 151
Side, is formed based on seal member from the face without the ink flow path 141b side at damped part 15
, the most there is not the obstruction ink load towards the flowing of ink entry 131a in the position of the convex of 155
The heart.It addition, the most there is not the worry damaging damping effect based on flexible membrane 152.
As shown in Figure 1 and Figure 2, the pressure adjustment hole 154 preferably sealed by seal member 155
It is configured at the portion corresponding with the outside of the configuring area of the ink entry 131a at substrate 13 opening
Position.That is, when damped part 15 being projected from the direction vertical with the face 13a of substrate 13,
The position that pressure adjustment hole 154 and seal member 155 are configured is positioned at ratio ink entry 131a
The more outward position of configuring area.
Thus, even if the thermohardening type resin before the relatively low solidification of viscosity is from pressure adjustment hole 154
Drip to the inside of flexible membrane 152, also can depart from from the configuring area of ink entry 131a, because of
This can reduce the shadow that the thermohardening type resin dripped brings to damping effect based on flexible membrane 152
Ring.Even if it addition, pressure adjustment hole 154 is arranged at flexible membrane 152, also due to sealing
Part 155 departs from from the configuring area of ink entry 131a, it is possible to reduce seal member 155
Hinder the ink worry towards the flowing of ink entry 131a, and also be able to reduce largely
Damage the worry of damping effect based on flexible membrane 152.
From not only guaranteeing ink flow path 141b but also play damping effect based on flexible membrane 152 efficiently
From the viewpoint of, preferably damped part 15 is configured that ink entry 131a and flexible membrane 152
Separating distance D than the separation between adjacent channel column ink entry 131a, 131a each other away from
Little from d.
Separating distance D is hanging down towards the flexible membrane 152 of damped part 15 from ink entry 131a
Straight distance.As shown in Figure 4, by the ink entry 131a of the channel column adjacent along Y-direction,
When separating distance between 131a is set to d1, d2, d3, this separating distance D is preferably D ＜
D1 and D ＜ d2 and D ＜ d3.
Specifically, damped part 15 is so that separating distance D is at the ink with adjacent channel column
All than this distance in distance d1 between entrance 131a, 131a, the comparison of any one of d2, d3
The mode that d1, d2, d3 are little, is arranged in shared ink chamber 141.Separating distance d1, d2, d3
It is the ink entry (as ink entry A) in a channel column, passage adjacent thereto
Closest between the ink entry (as ink entry B) of ink entry A in row
Beeline.This separating distance d1, d2, d3 are generally formed at the ink of adjacent channel column
The width in gap between the row between entrance A, B.Separating distance d1, d2, d3 may not be phase
Same value.
Thus, in the case of observing damped part 15 from ink entry 131a, to damped part
The distance that the distance of the flexible membrane 152 of 15 compares the ink entry 131a of neighbouring channel column is near,
Therefore, it is possible to make from passage 121 by ink entry 131a to propagating in shared ink chamber 141
Composition in pressure wave, towards damped part 15 advance is absorbed by flexible membrane 152 immediately and declines
Subtract.Therefore, it is possible to improve the effect of the impact of the crosstalk reduced between adjacent channel column.
For the ink gun 1 shown in present embodiment, straight line as shown in dashed line in figure 2
L is such, and ink entry 131a, ink outlet 121a and nozzle 111 are arranged in straight line
On, and the flexible membrane 152 of this straight line L and damped part 15 intersects.According to this structure, energy
Towards the pressure wave of damped part 15 in enough making to result from passage 121 and from ink entry 131a
Composition is directly absorbed by flexible membrane 152 and decays, and therefore the assimilation effect of pressure wave is the highest and can
It is reduced the effect of the impact of crosstalk significantly, thus preferably.
Make damped part 15 and ink entry 131a across separating distance D the means that configure do not have
Particularly requirement.Such as shown in Fig. 5, enumerate and be protrusively provided oriented substrate at damped part 15
The example of an appropriate number of foot 157 that 13 sides are prominent.If making this foot 157 and substrate 13
Face 13a abuts, then can carry out easily regulation separating distance D by the projecting height of foot 157.
Foot can also be arranged at the side of damping framework 151.
It addition, although not shown but it also may by foot is protrusively provided in the face of substrate 13
13a is upper or sets up pillar between the internal face of damped part 15 and shared ink chamber 141, from
And support damped part 15.
Damped part 15 is formed as utilizing flexible membrane 152 to cover whole ink entries
The size of 131a.That is, as it is shown in figure 1, when from substrate 13 be provided with ink entry 131a
Direction vertical for face 13a time damped part 15 is projected, damped part 15 comprises ink
Entrance 131a's is whole.Thereby, it is possible to utilize damped part 15 to make from whole passages 121
Pressure wave attenuation.It addition, the absorbent properties that can reduce pressure wave in each passage 121 are produced
The situation of raw difference.Therefore, it is possible to make the minimizing effect of the impact of crosstalk become between each passage 121
Uniformly, from but preferred mode.
Further, for damped part 15, assuming that flexible membrane 152 is the situation of tabular surface
Under, if this flexible membrane 15 is parallel with the face 13a of substrate 13, then for whole passage 121 energy
Enough damping effects that balancedly plays, thus preferably.
But, in the present invention, if damped part 15 is configured at least one ink entry 131a
With the separating distance D of flexible membrane 152 than this ink entry 131a with include that being communicated in this ink enters
Between the passage 121 of mouth 131a ink entry 131a in the adjacent channel of interior channel column arranges
The little position of separating distance, then damping effect can be utilized to make from this ink entry 131a's
Pressure wave attenuation such that it is able to be reduced the effect of the impact of the crosstalk brought to adjacent channel 121
Really.
Certainly, pressure wave damped parts 15 before arriving neighbouring ink entry 131a are made to decay
The quantity of ink entry 131a The more the better.That is, from the viewpoint of the impact reducing crosstalk,
Preferably damped part 15 is configured to, so that ink entry 131a and the flexibility of damped part 15
Distance between separating distance D ratio and the ink entry 131a of neighbouring channel column of film 152 is little
The ratio of the quantity of ink entry 131a that configures of mode at the number of whole ink entry 131a
More than the 90% of amount.
Additionally, when flexible membrane 152 shape in the environment of the use temperature of ink of damped part 15
In the situation (situation shown in single dotted broken line in Fig. 3) of the flexure plane being in depression, preferably by soft
The position caved in most of property film 152 and closest between the ink entry 131a at this position away from
From the separating distance D coming regulation ink entry 131a and flexible membrane 152.Even if in this case,
Though which ink entry 131a, to flexible membrane 152 distance all than be adjacent to its channel column
Ink entry 131a between distance near such that it is able to be significantly more reduced adjacent
The effect of the impact of the crosstalk between row.
Although the damping framework 151 of damped part 15 is formed by the material with rigidity, but preferably
Formed by metal at least partially.It is said that in general, metal pyroconductivity compared with ink (liquid)
Higher, therefore, it is possible to make the Temperature Distribution sharing the ink in ink chamber 141 promptly become uniform.Make
For metal, such as, metal that the pyroconductivities such as aluminium, copper, stainless steel good can be preferably used.This
The metal of sample may be used for damping the wall of a part for framework 151, it is also possible to is used for damping framework
The entirety of 151, but preferably at least exist in the way of directly contacting with the ink in shared ink chamber 141
The surface of damping framework 151 is exposed.
Though the ink used in the present invention not particularly requirement, but it is preferably used such as gel
UV ink, ceramic ink etc. need to be heated up to advise by ink by heating mechanisms such as heaters like that
Fixed temperature also makes the viscosity of ink be reduced to be suitable to the ink of the viscosity of discharge.This is because, although
Different because of the kind of ink, but such as use temperature gel UV of less than 90 DEG C more than 60 DEG C
The use temperature of the inks such as ink and other inks are in a ratio of high temperature, and the gas of dampening chamber 153 is easy
Expand largely, therefore obtained significant effect by the present invention.
In the present embodiment, it is configured with a damped part 15 in shared ink chamber 141, but also may be used
To configure multiple damped part 15 in shared ink chamber 141.It addition, the planar shaped of damped part 15
Shape is not limited to rectangular-shaped, it is also possible to be that toroidal, elliptical shape, polygon etc. are arbitrary
Shape.
(manufacture method of damped part)
It follows that use a Fig. 6～Fig. 9 example to the manufacture method of above-mentioned damped part 15
Illustrate.
For damped part 15, when making dampening chamber 153 and ft connection to resistance
The gas of Buddhist nun room heats, and then closes from outside by dampening chamber 153, thus by heated
Gas confinement (inclosure) is in dampening chamber 153.Hereinafter, the concrete example of preferred manufacture method is entered
Row explanation.
First, prepare in advance and be formed with the damping framework 151 in pressure adjustment hole 154 in a part.
Then, after adhesive 156 is coated on the opening edge 151a of damping framework 151, flatly draw
Stretch and flexible membrane 152 (Fig. 6) is set.Though there is no particular limitation for adhesive 156, but in this enforcement
Mode uses heat-curing type adhesive.
It follows that the damping framework 151 that stretching is provided with flexible membrane 152 is arranged in oven 100
In, and make adhesive 156 solidify (Fig. 7) by the solidification temperature being heated to adhesive 156.
By using oven 100, it is possible to make adhesive 156 solidify efficiently.
If adhesive 156 is cured, then by the damping framework 151 of band flexible membrane 152 from oven
Take out in 100, use heating arrangements that the gas of dampening chamber 153 is heated (Fig. 8) afterwards.
As heating arrangements, heating plate 200 is preferably used.The surface 200a of heating plate 200 is in flat
Tabular, therefore, it is possible to directly and equably to the gas of dampening chamber 151 to enter in the way of overall
The efficient heating of row.Thus, it is also possible to make the difference of the performance of each product less.
Make the surface 200a facing to heating plate 200 of flexible membrane 152 side, and in dampening chamber 153
By pressure adjustment with hole 154 with damping framework 151 ft connection state under, Ge Zherou
Property film 152 carries out the heating of the gas of dampening chamber 153.Now, the gas in dampening chamber 153
Although expanding, but can be from pressure adjustment hole 154 to the outside release of dampening chamber 153, therefore
Flexible membrane 152 will not be heaved or peel off, thus maintains tabular surface.
Afterwards, proceed by from outside for pressure adjustment hole 154 and performed by seal member 155
Sealing operation, and block pressure adjustment hole 154, thus by the gas confinement (envelope after heating
Enter) in dampening chamber 153 (Fig. 9).
Here, it is preferred that when the temperature of gas of dampening chamber 153 ink in shared ink chamber 141
When using more than the 90% of temperature, seal member 155 is utilized dampening chamber 153 to be closed.Thus,
When damped part 15 is in the environment of the use temperature of ink, the face shape of flexible membrane 152
Become near flat face or the flexure plane of depression, thus without constriction ink flow path 141b.
Here, it is preferred that, near flat face be the temperature of the gas in dampening chamber 153 be ink
Closing (sealing) time institute's shape in pressure adjustment hole 154 is completed under conditions of using temperature ± 10%
The face become.
It addition, it is also preferred that, in the temperature of the gas of dampening chamber 153 is in shared ink chamber 141
During more than the use temperature of ink temperature, seal member 155 is utilized dampening chamber 153 to be closed.
Thus, when damped part 15 is in the environment of the use temperature of ink, it is possible to make flexibility
The face of film 152 is reliably formed the flexure plane near flat face or depression.
It is more preferably, when making damped part 15 be in the environment of the use temperature of ink
The face of flexible membrane 152 is formed as tabular surface.Tabular surface is the temperature of the gas in dampening chamber 153
It it is the closing (sealing) completing pressure adjustment hole 154 under conditions of use temperature ± 5% of ink
Time the face that formed.By forming tabular surface, it is possible to balancedly play for whole passages 121
Damping effect, the most more preferably.That is, it is also preferred that the temperature working as the gas of dampening chamber 153 is in
When sharing the use temperature of ink in ink chamber 141, utilize seal member 155 by dampening chamber 153
Close.
In the present embodiment, the face of the damping framework 151 in the side contrary with flexible membrane 152
It is configured with pressure adjustment hole 154, therefore, it is possible to make flexible membrane 152 side and heating plate 200
Sealing operation is easily carried out under the aspectant state of surface 200a.It addition, can directly utilize
The heat of heating plate 200 makes the seal member 155 being made up of thermohardening type resin solidify, the most also
Sealing operation can be simplified.
The sealing in pressure adjustment hole 154 is not limited to the temperature ratio of the gas in dampening chamber 153
Situation about starting when using temperature height, such as can also be when the temperature that the use temperature than ink is low
Start.If seal member 155 that is thermohardening type resin are uncured, even if then to dampening chamber 153
Gas heat further, it is also possible to bleed off pressure via uncured thermohardening type resin
Power, the opportunity therefore sealing beginning, there is no particular limitation.Additionally, from yield rate (rate)
Viewpoint considers, preferably proceeds by the sealing in pressure adjustment hole 154 when reaching and using temperature.
Such as by configuration thermometer (not shown) near damping framework 151, and measure resistance
The environment temperature of the surrounding of Buddhist nun's framework 151 such that it is able to whether judge the gas in dampening chamber 153
Reach the use temperature of ink.
From the viewpoint of making the sealing operation that performed by seal member 155 good, preferably pressure
Adjustment by the size in hole 154 at below diameter 3mm.Particularly as shown in the embodiment will
Thermohardening type resin is used as in the case of seal member 155, from preventing the uncured heat that has been coated with
Gel-type resin is from the viewpoint of pressure adjustment hole 154 enters in dampening chamber 153, the most directly
Footpath is 1mm.Though hole shape is not limited to circle, but in the case of non-circular, pressure adjusts
With the diameter in hole 154 be in the case of the circle being replaced into the area identical with the aperture area in hole should
Diameter of a circle.
Carry out being held by seal member 155 in the case of maintaining heated condition based on heating plate 200
The pressure of row adjusts with the sealing in hole 154.This is because, if in the heat as seal member 155
Before gel-type resin solidification, the temperature of the gas in dampening chamber 153 reduces, it is likely that because of gas
Shrink and be thermally cured type resin and import from pressure adjustment hole 154, and in flexible membrane 152
Face forms film based on thermohardening type resin.In such a situation it is preferred that by flexible membrane 152 and heating
Distance between the surface 200a of plate 200 remains below 3mm, thus suppresses damping as far as possible
The temperature change of the gas in room 153.
Because seal member 155 that is thermohardening type resin solidify by close for pressure adjustment hole 154
Envelope, thus obtain the damped part 15 having gas in dampening chamber 153 inner sealing (inclosure).Due to
Gas in dampening chamber 153 reaches to carry out during the use temperature of ink pressure adjustment hole 154
Seal, so when this damped part 15 is under normal temperature environment, the gas in dampening chamber 153
Body shrinks, thus the face of flexible membrane 152 forms the flexure plane of depression.On the other hand, in damper portion
When part 15 is in the use temperature of ink, the gas expansion in dampening chamber 153, but flexible membrane 152
Face be the degree of the flexure plane forming near flat face or depression as illustrated in fig. 3, thus not
Convexly significantly can heave and constriction ink flow path 141b to ink entry 131a side.
According to above-mentioned manufacture method, only by the gas in dampening chamber 153 is heated and at this
Gas reaches to utilize seal member 155 by close for pressure adjustment hole 154 during the use temperature of ink
Envelope, it becomes possible to the pressure carrying out the gas in dampening chamber 153 as simply as possible adjusts.Therefore,
Reach to use even if can be easily manufactured to play damping effect and share the ink in ink chamber 141
Temperature compliant film 152 also will not hinder the damped part 15 of the providing ink towards passage 121.
Additionally, the gas in above manufacture method, in made dampening chamber 153 by heating
When reaching the use temperature of ink, proceed by the sealing operation for pressure adjustment hole 154,
But particularly it is used as in the case of seal member 155 being thermally cured type resin, it is also possible in damping
Gas in room 153 reaches to proceed by sealing operation before ink uses temperature.In this case,
Continue (when thermohardening type resin is uncured) at the end of the sealing not performed by seal member 155
Heating, the gas of expansion is pushed uncured thermohardening type resin open and is released to outside, thus
Making of ink can be up to sealing finish time (the solidification finish time of thermohardening type resin)
With the gas confinement (inclosure) of temperature in dampening chamber 153.
It addition, in above manufacture method, employ oven when making adhesive 156 solidify
100, but as shown in Figure 10, it is also possible to utilize cover 300 to cover with being configured at heating plate 200
On the damping framework 151 of flexible membrane 152.Owing to the heat of heating plate 200 can be utilized to make cover 300
Internal temperature is warming up to condition of cure temperature, even if so not using oven 100 also to be able to height
Effect adhesive 156 is made to solidify.Further, since can be immediately moved into resistance after adhesive solidifies
The gas of Buddhist nun room 153 carries out the operation heated, so also being able to simplify manufacturing process.
