Abstract
The utility model discloses a developing solution concentration measuring device for a thermosensitive plate automatic developing machine, which includes a developing solution tank, wherein two electrodes are fixed in the developing solution on the edge of the developing solution tank; leads are led out from the two electrodes respectively; the other ends of the leads are connected with a electric conductivity measuring instrument; and the distance between the two electrodes is 15 cm. Through adopting the device, the electric conductivity corresponding to the upper limit value (within the specified range) of the developing solution and the electric conductivity corresponding to the lower limit value (within the specified range) of the developing solution are measured firstly; during the production process, if the displayed electric conductivity is between the upper limit value and the lower limit value, the concentration of the developing solution conforms the requirement; and if the measured electric conductivity is lower than the lower limit value, the developing solution with high concentration is required to be added. The developing solution concentration measuring device is simple in structure and low in cost, and is convenient and quick to monitor.
Description
Technical field
The utility model relates to offset press production line servicing unit, and especially the temperature-sensitive version is dashed version machine solution level measurement mechanism automatically.
Background technology
Advantages such as offset printing is a kind of as typography, and is real, bright-colored with its printing product China ink bed thickness, that saturation degree is high, the forme press resistance rate high, print quality is stable, print speed printing speed is fast occupy extremely important status in printing packaging and picture and text publishing area.The packaging product that the offset printing mode is produced has advantages such as pattern is meticulous, mass colour is bright-coloured, picture and text are clear.Compare with serigraphy with letterpress, offset printing can make the contrast of colored original and color obtain more true to nature duplicating; Compare with intaglio printing, offset printing has the advantage that the plate-making cycle is short, the plate-making expense is low, the reduction of contrast pattern is meticulousr.At present, offset press adopts CTP, before the whole production line operation; Need carry out the preceding plate-making of printing preliminary work; In the developing process of plate-making because original production equipment can't be monitored the variation of solution level, the operator often by rule of thumb or sensation measure the concentration of developer solution; Easy like this causing caused waste product in batches because concentration conforms to the symbol requirement and produces useless plate.
By on can know that above-mentioned existing temperature-sensitive version is dashed a version machine solution level measurement mechanism automatically, on reality is used, obviously has defective and exists, and remain to be improved.
Thus, the improving of the above-mentioned defective of the utility model thoughts is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
Summary of the invention
To the weak point of prior art, the utility model aims to provide a kind of temperature-sensitive version and dashes version machine solution level measurement mechanism automatically, to guarantee to monitor at any time the change in concentration of developer solution.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts: a kind of temperature-sensitive version is dashed version machine solution level measurement mechanism automatically; Comprise dipper; In the developer solution at dipper edge, fixedly install two electrodes, draw lead respectively on said two electrodes, the other end of lead connects the conductivity measurement appearance.
Said two distance between electrodes are 15 centimetres.
After adopting said apparatus; Measure corresponding conductance of the higher limit of solution level in satisfactory scope and the corresponding conductance of lower limit earlier; In the production run if the conductance that shows between higher limit and lower limit, then the concentration of developer solution meets the requirements; If the conductance that records is lower than lower limit, then need add the high developer solution of concentration.
The utility model is simple in structure, cost is low, monitors convenient and swift.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the local A of Fig. 1 is to view;
In the accompanying drawing: 1 dipper, 2 conductivity measurement appearance, 3 electrodes, 4 support bars.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, shown in Figure 2; Elder generation's horizontal fixed is provided with pair of support rods 4 at dipper 1 edge, the electrode 3 that fixedly installs in an end of support bar 4 respectively, and electrode 3 is insulation with dipper; Draw lead respectively on said two electrodes 3, the other end of lead connects conductivity measurement appearance 2.
Distance in the present embodiment between two electrodes 3 is 15 centimetres, under this condition, measures corresponding conductance of the higher limit of solution level in satisfactory scope and the corresponding conductance of lower limit respectively; Certainly, two distance between electrodes can also extend or shorten, and still, after the variable in distance, will measure corresponding conductance and the corresponding conductance of lower limit of the higher limit of solution level in satisfactory scope with this understanding equally between the electrode.In operating process, only need to observe the variation of developer solution conductance, also just know the variation of solution level, guarantee that the solution level measurement is within satisfactory scope.
The above; Be merely the embodiment of the utility model embodiment; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model discloses, and conspicuous variation or replacement all should be encompassed within the protection domain of the utility model.
