Description
Technical field
This utility model belongs to the technical fields such as printing technology, typography, machinery, Electronic Control, numerical calculation, is specifically related to a kind of accurate ink feeding system of printer digitized.
Background technology
At present, ink printer is equipped with the ink fountain of mechanical type ink key, as the ink-feeding device of the single colour cell of printer.This ink fountain can be automatically controlled (driving with motor) to the control mode of ink key, it is also possible to is manual (with screw rod screw etc.).Generally, a printed patterns, after color separation, form 4 colors or more color, after making color version double exposure on the printer respectively, be reduced into chromatograp.Each colour cell of printer completes a monochromatic printing work.The printing format of each colour cell is unanimously divided into some ink-covered areas, and each colour cell is equipped with an ink fountain, each corresponding ink-covered area of ink key.The opening degree adjusting a black key just can control and regulate the size of this ink-covered area ink supply amount.When actual print production, according to the dot area of each ink-covered area of each monochromatic unit, the opening degree arranging corresponding ink key reaches the control to printing color.With the big ink-covered area of ink amount, its ink key needs to tune up opening, otherwise, it is accomplished by turning opening down with the ink-covered area that ink amount is little and the most thoroughly closes the black key of this ink-covered area.The unlatching of Mo Jian and the critical point of Guan Bi are referred to as zero point.Mo Jian is calibrated a folding angle value from zero point to maximum opening, and different printer manufacturers sets respective folding angle value scope.Mo Jian is not the control unit of metering type, and its folding angle value is the relative reference value that each printer system provides.
Owing to Mo Jian is engineering goods, the actual adjustment size range of opening is the least (usual range is at 0-0.2 millimeter) so that the calibration of zero-bit, opening degree the difficulty such as to be precisely controlled bigger；The concordance between each ink key on same ink fountain is more weak；Absolute accuracy and relative accuracy all cannot ensure；In addition to ink fountain and Mo Jian, conventional presses ink supply mode and mechanism are also used other Mechanical Contact and mechanical control method to transmit ink, concrete, the distributor rollers worked in a swing fashion, time of contact between ink foundation roller rotating speed, ink roller and the control accuracy of action, these mechanisms and operation principle make the calculating of actual ink supply amount, adjust and control more difficult, it is impossible to precise quantification.For these problems, printing-flow have employed multiple technologies, concrete, have set each ink fountain put ink curve to approach the corresponding relation between ink supply amount and folding angle value, but all can not inherently realize ink supply accurate quantified controlling.
Due to these reasons, conventional presses ink feeding system, with " analog quantity " and method work qualitatively, can only judge ink supply " many " or " lacking " by detection leaflet, it is impossible to know effective supply amount of ink.
Summary of the invention
The purpose of this utility model is to overcome the deficiency in existing printer ink-supplying mechanism and function and defect, it is provided that a kind of accurate ink feeding system of printer digitized.
It is as follows that this utility model solves the technical scheme that its technical problem used:
