Abstract
The utility model relates an ink supply system of a piezoelectric nozzle hand-held ink-jet printer. The ink supply system includes an ink box which stores the ink, an ink supply needle adapter, a piezoelectric nozzle, a filter, a thin ink supply tube, a thick ink supply tube and an ink supply tube adapter. The ink supply needle adapter is communicated with the filter via the thin ink supply tube. The filter is communicated with the ink supply tube adapter via the thick ink supply tube. The ink supply tube adapter is communicated with the nozzle. When the ink box is inserted into the ink supply system, the ink flows into the thin ink supply tube via a channel in the ink supply needle adapter, and then the ink flows into the filter via the thin ink supply tube. The ink enters into the thick ink supply tube after passing the filter, and next the ink is sprayed after entering into the nozzle. The ink supply system is characterized by setting the optimum relative positions of the ink box and the nozzle when the nozzle sprays ink sideways or downward, and the relative positions do not change whether the nozzle sprays sideways or downward. A flow expanding device adjusts the flow speed of the ink, so the ink supply system is located at an ideal ink supply point, and consequently the phenomena, like ink suspension, ink dripping and ink shortage are prevented. The advantage is that the problems, like ink suspension, ink dripping and ink shortage that occur when the ink supply system of the piezoelectric nozzle hand-held ink-jet printer sprays ink sideways or downward are solved, and whether the nozzle sprays sideways or downward, the nozzle ink suspension or line discontinuity can not happen, and the clear and normal spraying effect is realized.
Description
The utility model belongs to the manufacturing field of ink jet numbering machine equipment, particularly the ink feeding system of piezoelectric type spray (Piezoelectric) Handheld type code spraying machine.
Background technology
Hand-held ink jet numbering machine performance and characteristics:
Hand-held ink jet numbering machine is furnished with large capacity rechargeable type lithium battery, make its portability convenient, can be widely used in the coding signs such as the external packing of food, beverage, wine etc. and various steel pipe, woven bag, plasterboard, the place to use can be in the workshop, also can be in the warehouse, logistics freight yard, office etc., but spray printing date of manufacture, operation serial number, produce order of classes or grades at school number, false proof anti-channel conflict code (or stealthy character), Business Name, graphic icons etc.
Another specific function-antiforge function of hand-held ink jet numbering machine can use invisible printing ink false proof.But the invisible printing ink spray printing goes out hidden pattern or literal, and stealth is namely without color, and naked eyes be cannot see, but under UV-irradiation, can present clear light, bright spray printing content.At present most domestic pharmaceutical product packaging or some have the product of dividing the sales region all to adopt the invisible printing ink coding false proof.
According to the practical situations at present domestic and international shower nozzle technology and hand-held ink jet numbering machine market, hand-held ink jet numbering machine mainly uses following several shower nozzle technology:
1, heat foamable formula ink-jet (TIJ-Thermal Ink-Jet) shower nozzle
The operation principle of heat foamable formula ink-jet technology is by the electric heating assembly (normally thermal resistance) on the ink jet-print head (silicon base of inkjet ink chamber), in 3 microseconds, be heated to rapidly 300 degrees centigrade, make the liquid printing ink vaporization of nozzle bottom and form bubble, this steam blanket avoids ink and heating component isolation with all ink heating in the nozzle.After heating signal disappeared, the heating ceramic surface began cooling, but residual waste heat still impels bubble to expand into rapidly maximum in 8 microseconds, and a certain amount of ink droplet of consequent pressure compression overcomes surface tension crushing failure at high speed delivery nozzle.Along with temperature continues to descend, bubble begins to be contraction state.The former ink of extruding outside spray orifice be subject to bubble break strength traction and form the dispersion ink droplet, the rear end makes ink droplet begin to separate because of the contraction of ink, ink behind the bubble collapse in ink droplet and the nozzle just separates fully, ink then sees through lasting inflow of the runner that is communicated with ink-jet district and ink storage district and replenishes, thereby finishes the process of an ink-jet.The result that ink droplet of every ejection all is above-mentioned flow process Collaboration.
Heat foamable type print speed is very fast, only is ejected through just pushing but shortcoming is ink, and strength can not be concentrated, and ink dot is vulnerable to inertia effects and print head and pulls unclearly, and produces inhomogeneous or ink residue.Another problem is, the ink-jetting style of bubble type, and because its print head often is under the high-temperature situation, heat meeting is so that lettering easy loss on first watch, therefore need reduce cost with the mode that print head and ink cartridges are unified.
With the Handheld type code spraying machine of heat foamable formula ink-jet (TIJ-Thermal Ink-Jet) shower nozzle manufacturing because the pixel of its shower nozzle is high, font that can the spray printing high-resolution or bar code trade mark etc., but can't use quicksetting ink, can't use in the impermeability material.As using in permeability materials such as timber, paper, can not use in impermeability materials such as metal, plastics.
2, piezoelectric type shower nozzle (Piezoelectric)
The piezoelectric type shower nozzle is by applying voltage to piezo-electric crystal, making it to occur at a high speed and slight deformation, thereby the printing ink in the nozzle is extruded.Do the time spent when piezo-electric crystal is subject to extraneous pulse voltage, piezo-electric crystal just produces distortion, thereby causes the volume reducing of nozzle ink cavity.Like this, an oil dripping China ink just penetrates from nozzle.Then, piezo-electric crystal restores to the original state, because surface tension effects, new printing ink enters nozzle.By the nozzle that is arranged side by side in a large number, just can obtain desirable spray printing width and resolution.
(annotate: piezo-electric crystal is that the semiconductor piezoelectric crystal material by a kind of PZT of crying is made)
Because what use is the piezoelectric type technology, and the pixel of its shower nozzle is high, font that can the spray printing high-resolution or bar code trade mark etc. also can use quicksetting ink simultaneously, can use in the impermeability material with the Handheld type code spraying machine of piezoelectric type shower nozzle manufacturing.Can spray printing timber, the infiltration material such as paper, but also impermeability materials such as spray printing metal, plastics.
3, drip-type (drop on demand be called for short DOD formula) shower nozzle as required
The operation principle of drip-type as required: shower nozzle is comprised of a plurality of high-accuracy valves, and when coding, the valve corresponding with font opens and closes rapidly, and ink relies on inner constant pressure ejection, forms character or figure on the surface of motion.What data signal produced at paper is a China ink, rather than Chinese stick stream.
Handheld type code spraying machine with as required drip-type shower nozzle manufacturing uses as required drip-type technology owing to shower nozzle, spray printing effect out is point-like, can use quicksetting ink, can be on the impermeability material coding use but font that can not the spray printing high-resolution or bar code trade mark etc.
At present, though the Handheld type code spraying machine ink feeding system multi-directionally coding of the as required drip-type shower nozzle on the market, owing to being dot matrix, the font of ejection is raster font.The height of a word generally forms by 7 to 16, thus can't spray printing brand logo and bar code because counting less, in the scope of application certain limitation is arranged.
Next is the hand-held ink jet numbering machine ink feeding system of high-resolution of thermal bubble type shower nozzle, can be towards the side, spray printing down, but spray printing literal, brand logo and bar code.But since its can only spray printing on permeable material (such as plank, carton etc.), therefore on using significant limitation is arranged also.
Existing piezoelectric type shower nozzle (Piezoelectric) Handheld type code spraying machine ink feeding system comprises print cartridge, filter, shower nozzle and to the ink-feeding tube of shower nozzle ink supply, it is realized according to siphon principle the control for ink dot, regulate for ink dot by the height of adjusting print cartridge and shower nozzle or with flow-limiting valve, realize appropriate ink supply, the defective of this ink feeding system is print cartridge and nozzle not to be arranged on best relative position, thereby it is the most suitable for ink dot that ink feeding system is in, and namely is in towards the side and suitable equalization point all down.When nozzle during towards the different directions coding, it is original suitable for ink dot just to have changed; When print cartridge when slightly high or body is slightly rare with respect to the height of nozzle, nozzle can be hung China ink, sticks with paste mouth or drip China ink; When print cartridge when slightly low or body is slightly dense with respect to the height of nozzle, the nozzle China ink that can break.When reality is used, can clear coding towards the side coding time, when being changed to down then nozzle China ink can occur hanging, stick with paste mouth or drip China ink; The clear coding of energy when coding down, broken string or disconnected China ink then can appear in nozzle when being changed to towards the side.So piezoelectric type shower nozzle Handheld type code spraying machine ink feeding system in the market has very large defective in the use.
