Description
Technical field
This utility model is related to printer field, refers in particular to a kind of wide format printer ink for ink-jet printer
Capsule.
Background technology
With scientific and technological development, the use commercially of present wide format printer is more and more extensive.
Wide format ink jet printer new at present, the flowing in order to improve ink supplements speed, overcomes long distance delivery
Pipe-line system resistance, the commonly used mode of malleation ink supply, that is, ink printhead is input to the pressure of superatmospheric
Position.In order to reach malleation ink supply, can guarantee that simultaneously again and make in printer not ink-jet printhead isolation come from pipeline ink
High pressure it is necessary to use a kind of device of belt switch, this device is often integrated in the ink sac with cushioning effect, such as Fig. 1-
Shown in 3.
This ink sac include ink bag main body 1a, little plastic disc 1b, the first spring 1c, plastics boss 1d, rubber seal 1e,
Big plastic disc 1g, second spring 1h.In printhead not ink-jet, the first spring 1c promotes plastics boss 1d to ink sac, thus drawing
Live in rubber seal 1e (rubber seal 1e is fixed on plastics boss 1d), so that valve switch is in and close sealing state, and
Ink pressure direction in pipeline now consistent with the drawing direction of the first spring 1c it is ensured that sealing reliability.And work as
After printhead active ink-jet under the driving of circuit, the inner volume of printhead can form certain vacuum, is communicated to ink sac
Thin-film chamber 1f end, in the presence of normal atmosphere outside thin film, extrude second spring 1h, promote plastics boss 1d, pipe
Ink in road adds to rapidly in the thin film cavity volume of negative pressure at positive pressure.With supplementing enough ink, thin film
Pressure in cavity volume rises rapidly, and after reaching predetermined value, the first spring 1c pulls plastics boss 1d to be re-closing off pipeline, thus tieing up
Hold certain negative pressure state in thin film cavity volume, ensured that printhead will not drip ink in not ink-jet.Ink is transported to by ink sac
On printhead, supply printer normally uses.
Ink sac currently on the market is typically all to be assembled together in spring by plastics boss 1d and rubber seal 1e
Elastic force effect lower seal.Cylinder on plastics boss is thinner be easy to crooked, when cylinder is crooked plastics raised head face and
The place of ink bag main body contact may not be adjacent to it may appear that plastics raised head face and the little disc of ink bag main body are not parallel, this
Sample may result in rubber seal unbalance stress, and the sealing of such ink sac is just unreliable, can directly influence making of printer
With.
In addition, the local sealing ring of ink sac head and the assembling of printhead nipple currently on the market is all using common monolayer
Monolayer sealing ring 1i in sealing ring, such as Fig. 3, such monolayer sealing ring is inserted in the fooled ink sac of printhead nipple and is shaken by the external world
During dynamic or strength, ink sac be easy to crooked, the cooperation between the crooked rear sealing ring of ink sac and nipple just unreliable it may appear that
The situation of gas leakage, now air can enter printhead, can soon result in printhead break ink.
Utility model content
In order to solve deficiencies of the prior art, this utility model provides one kind and is applied to large-format ink-jet to be beaten
The ink sac of print machine, substantially increases the reliability of ink sac switch seal, and also improve ink sac to be inserted into printhead nipple close simultaneously
The reliability of envelope, thus ensure that the stability of wide format printer continuous ink feeding.
A kind of wide format printer ink sac, including the Large Copacity membrane well between ink bag main body, and ink bag main body and thin film
Room, Large Copacity thin-film chamber lower end is provided with the ink sac head connecting printhead nipple, and thin film is provided with big plastic disc, big plastics
Disk is connected with ink bag main body by second spring；It is provided with little plastic disc, the first spring and plastics round platform in ink bag main body, the
One spring is fixed between little plastic disc and plastics round platform；It is fixed with plastic cylinder, plastic cylinder on described big plastic disc
Through the through hole of second spring and ink bag main body, it is provided between the outside of ink bag main body through hole, plastics round platform and ink bag main body
Sealing ring.
Preferably, described big plastic disc and plastic cylinder are assembled together.
Preferably, plastic cylinder inserts the in the hole of big plastic disc, and is fixed by hot melt.
Preferably, described sealing ring is O-ring, and plastics round platform is not assembled together.
Preferably, described ink sac head is provided with the sealing ring of double-deck convex tendon.
Preferably, described bilayer convex tendon sealing ring fixed by snap in ink sac head.
Below this utility model is described further：
Wide format printer ink sac, including ink bag main body, little plastic disc, the first spring, plastics round platform, rubber seal
Circle, big plastic disc, second spring, plastic cylinder, double-layer seal rings and buckle, jumbo film damper chamber.
Cylinder, cylinder and round platform is not had to be separate above this utility model plastics round platform.Rubber seal and moulding
Material round platform is not assembled together, and can preferably make sealing ring be adjacent to the sealing surface of ink bag main body.
Described little plastic disc and plastics round platform are connected together by the first spring, described big plastic disc and ink bag main body
Connected together by second spring, together with plastic cylinder assembled in advance, plastic cylinder is inserted into greatly described big plastic disc
The in the hole of plastic disc, is then thermally melted in plastic cylinder on big plastic disc with electric cautery, makes plastic cylinder and big plastics circle
Disk becomes an entirety.
The wide format ink jet printer ink sac that this utility model provides, improves ink sac intermediate switch structure, because plastics
After cylinder and plastics round platform split, even if plastic cylinder is crooked, do not interfere with plastics round platform it is ensured that plastics round platform yet
It is parallel with ink sac contact surface, certainly uniformly, substantially increase the sealing of ink sac intermediate switch can for the stress of such sealing ring
By property.
Ink sac head using double-deck convex tendon sealing ring it is ensured that between ink sac and printhead nipple sealing reliability,
So that printing function is normally effectively worked, substantially increase the print quality of wide format printer, thus people couple more can be met
Printer speed and the demand of quality.
