Abstract
The invention discloses a viscosimeter for an ink-jet printing machine. The viscosimeter comprises a measuring tube, wherein a heavy ball is filled in the measuring tube; an outer busing is sleeved outside the measuring tube; the upper end of the measuring tube and the upper end of the outer bushing are connected with each other through an upper end head; the lower end of the measuring tube and the lower end of the outer bushing are connected with each other through a lower end head; the upper end head and the lower end head are provided with an ink outlet and an ink inlet which are communicated with a cavity of the measuring tube respectively; and a position sensor for detecting a top dead point and a bottom dead point of the heavy ball is arranged in the cavity between the measuring tube and the outer bushing and is connected with an electrical control device. Since a drop bead type detection mode in which the position sensor is provided is adopted in the viscosimeter, and the accurate time for dropping the heavy ball can be known by detecting the position of the heavy ball by the position sensor, the viscosity is analyzed and calculated, the ink viscosity can be stably controlled within a more accurate range, and the quality of ink-jet printing is guaranteed.
Description
Technical field
The present invention relates to the viscosimeter field, be meant a kind of viscosimeter that is used for the ink ink jet numbering machine especially.
Background technology
Why the ink ink jet numbering machine can go out information by spray printing; Mainly be that ink dot is charged; And the quality of charging also depends on the cooperation of breakpoint sequential and the quality of breakpoint except depending on charging signals, and the viscosity of ink is an essential condition that influences breakpoint; So a stable machine ink viscosity must be stablized the more accurate scope that is controlled at, and only in this way could guarantee the quality of spray printing.The viscosity detection method is a lot of at present, detection modes such as general ink jet numbering machine has float-ball type, probe-type, the pearl formula that falls, and comparing all has certain shortcoming: it is that ball float clings easily that float-ball type detects shortcoming, it is stifled that ink outlet is prone to; Probe-type mainly is to have ink outlet to be prone to stifled problem; The pearl formula that falls only detects low level, and a high position is judged (think after impact a period of time with ink and attain to a high place) according to the time, and reliability is low, precision is low.
Summary of the invention
Technical matters to be solved by this invention is: the viscosimeter that a kind of precision height, good reliability are provided.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of ink ink jet numbering machine comprises measuring tube with viscosimeter; Heavy ball is equipped with in the inside of said measuring tube, and the outer cover of said measuring tube is equipped with outer tube, and said measuring tube upper end is connected through upper end with the upper end of outer tube; The lower end of said measuring tube is connected through lower end with the lower end of outer tube; Be respectively equipped with the ink outlet and the ink entry that are communicated with said measuring tube inner chamber on said upper end and the lower end, installation is used to detect the top dead centre of heavy ball and the position transducer of lower dead center in the cavity between said measuring tube and the outer tube, and said position transducer is connected with electric control gear.
As a kind of preferred version; Described heavy ball is a metal ball; Described position transducer comprises two metal detectors,, said two metal detectors are installed in the cavity between measuring tube and the outer tube; And be arranged at the top dead centre and the lower dead center place of heavy ball campaign respectively, arrive top dead centre and the time of giving directions down so that detect heavy ball.
As a kind of preferred version, described electric control gear comprises a master controller, and said metal detector is electrically connected with master controller.
As a kind of preferred version, the inner chamber of described measuring tube opens extension gradually from the bottom to the top, and this kind structure helps flowing of ink, prevents moment China ink pressure fluctuation.
As a kind of preferred version; The end of said upper end and lower end is equipped with a protuberance; The two ends of said measuring tube be sleeved on the said protuberance and with the end seal setting of upper end and lower end, the two ends of said outer tube are sleeved on the periphery of said upper end and lower end and are fixedly connected through fastening swivel nut respectively with lower end with upper end.
After having adopted technique scheme, effect of the present invention is: because viscosimeter of the present invention has adopted the pearl formula detection mode that falls that position transducer is installed, when needs detect viscosity; Ink is squeezed into measuring tube up to the ink exit from the ink entry high pressure, and heavy ball is meanwhile pushed to the measuring tube top by ink, when position transducer after the top dead centre place detects heavy ball; Send signal to electric control gear; Heavy ball is subsequently descended by gravity effect in ink, detects heavy ball up to position transducer once more at the lower dead center place, sends signal to electric control gear once more; Can know the correct time that heavy ball is fallen through the signal of twice acquisition; Correct time analysis meter according to heavy ball is fallen is calculated k value, is controlled at a more accurate scope thereby can the ink viscosity be stablized, and has guaranteed the quality of spray printing.
Description of drawings

Embodiment
Through specific embodiment a kind of viscosimeter of the present invention is done further to describe in detail below.
The description of concerned direction is to be as the criterion with viscosimeter state in use among the present invention.
At first, the ink entry 9 of viscosimeter is communicated with to advance black pipeline respectively and goes out black pipeline with ink outlet 10, advances black pipeline and is provided with solenoid valve; When detecting viscosity, electric control gear 7 is opened solenoid valve, and ink is squeezed in the measuring tube 4 from ink entry 9 high pressure; Meanwhile metal ball is pushed to measuring tube 4 tops by ink, when last metal sensor 11 after the top dead centre place detects metal ball, send signal to electric control gear 7; Close solenoid valve, ink stops to squeeze into, and metal ball is descended by gravity effect in ink subsequently; Detect heavy ball 5 once more at the lower dead center place up to following metal sensor 6, send signal to electric control gear 7 once more, electric control gear 7 receives the signal timing to be stopped.Can know the correct time that metal ball falls through the signal of twice acquisition, calculate k value according to the correct time analysis meter that metal ball falls.
