Abstract
The utility model provides a solvent evaporation preventing ink recycling structure of ink-jet printing machine. The ink recycling structure comprises an ink box, a main pump, a jetting head and an ink recycling groove, wherein the jetting-head is connected to the ink box through a main ink supply tube, the main ink supply tube is connected with a first ink recycling tube, and a second ink recycling tube is provided with a throttling valve for regulating flow. The ink recycling structure not only can automatically recycle the ink to the ink box from the recycling groove, but also can avoid collecting the air to the ink box during the recycling process, thus, the solvent in the ink box is prevented from evaporating with the mixed air, the ink in the ink box is effectively prevented from becoming thick and sequentially blocking the jetting head.
Description
Technical field
The utility model relates to a kind of ink recovery mechanism of ink jet numbering machine, relates in particular to a kind of ink jet numbering machine ink recovery structure of avoiding solvent evaporates.
Background technology
Ink jet numbering machine is a kind of by software control, uses cordless at the equipment of the enterprising line identifier of product.Existing ink jet numbering machine applies certain pressure by main pump ink in the system, and ink is penetrated via the nozzle on shower nozzle.And will penetrate the continuous line of ink marker to split into frequency identical by being added in nozzle top crystal oscillation signal, equal and opposite in direction, the ink droplet that spacing is certain, then, ink droplet is charged respectively when passing through charging electrode, and its carried charge size is controlled by central processor CPU; Whether correct through detecting electrode detection ink droplet actual institute carried charge and phase place again; At last, charged droplets forms in deflecting electric field at deflecting electrode and deflects, penetrate from the nozzle of shower nozzle, beat respectively at the product surface diverse location, form required various word, the signs such as pattern are not recharged ink droplet and squeeze into the ink recovery groove, reenter the ink circulation system of machine intimate.At present, usually adopt compression pump with in the process in the ink recovery groove, the air of ink recovery groove can be incorporated in ink cassette along with ink, due to the solvent that is mixed with in ink cassette for the dilution ink, after entrained air in ink cassette, the solvent in ink cassette can along with the air volatilization of sneaking into, cause the solvent in ink cassette to reduce, thereby affect the ink viscosity in ink cassette, make ink normally to use.
The utility model content
The technical problem that the utility model solves is: a kind of ink jet numbering machine ink recovery structure of avoiding solvent evaporates is provided, not only can be automatically with in the ink recovery ink feed water tank in accumulator tank, and can avoid air is taken in ink cassette in removal process.
the technical solution of the utility model is: a kind of ink jet numbering machine ink recovery structure of avoiding solvent evaporates, comprise ink cassette, main pump, shower nozzle and ink recovery groove, described shower nozzle is connected to described ink cassette by main ink tube, described main pump is arranged on described main ink tube, described ink recovery groove be positioned at described shower nozzle under, it is characterized in that, be connected with the first ink recovery pipe on described main ink tube, and an end of described the first ink recovery pipe is arranged on main ink tube pipeline section between described main pump and described shower nozzle, the other end of described the first ink recovery pipe is connected to described ink cassette, be provided with Venturi tube on described the first ink recovery pipe, be connected with the second ink recovery pipe between described ink recovery groove and described the first ink recovery pipe, and an end of the second ink recovery pipe is arranged between the outlet and described ink cassette of described Venturi tube, be provided with the choke valve for adjust flux on described the second ink recovery pipe.
The outlet of the contiguous described Venturi tube of one end of described the second ink recovery pipe.
Be provided with the ink supply valve on described main ink tube.
the beneficial effects of the utility model are: the utility model is provided with the choke valve for adjust flux on the second ink recovery pipe, reduce by regulating choke valve the recovery speed that ink in the second ink recovery pipe is back to ink cassette, can avoid the air in the ink recovery groove to enter into ink cassette by reducing ink recovery speed, therefore the utility model not only can be automatically with in the ink recovery ink feed water tank in accumulator tank, and can avoid air is taken in ink cassette in removal process, thereby avoid the solvent in ink cassette to volatilize along with the air of sneaking into produces, effectively prevent ink in the ink cassette thickness that becomes, avoid the ink thick rear obstruction shower nozzle that becomes sticky.
