Referring to fig. 1, according to the method for detecting the printer ink anti-blocking head performance of the embodiment of the invention, the method for detecting the printer ink anti-blocking head performance comprises the following steps: placing printer ink in a container; dipping the printer ink in the container by a capillary tube; fixing the capillary tube dipped with the ink of the printer; the fixed time of the capillary was recorded by a timer, and the state of the printer ink in the capillary was observed and recorded. The state of the printer ink in the capillary includes that the position of the printer ink in the capillary is not changed, and the printer ink rises a certain distance in the capillary
Firstly, printer ink needing to detect the performance of a plug is placed in a container, and a capillary tube is convenient to dip the printer ink in the container; then dipping the printer ink in the container by using a capillary tube; after ink of a printer is dipped, the capillary tube can be fixed; the fixed capillary tube was set so that the end dipped with the printer ink faced downward, the fixed time of the capillary tube was recorded by a timer, and the state of the printer ink was observed by inverting the capillary tube after the set time had elapsed. If the printer ink still can flow downwards from the upper end in the capillary after the fixed time reaches the specified time, the anti-blocking performance of the printer ink reaching the state is better, otherwise, the anti-blocking performance of the printer ink is poorer, so that the ink blocks a pipeline in a nozzle of the digital printer, and the printing defects such as ink breaking or oblique spraying are caused. Therefore, the detection method for the anti-blocking performance of the printer ink utilizes the device with a simple structure, gives up direct use of the nozzle for the performance test of the plug, and can avoid the damage of the nozzle so as to increase the cost of maintaining equipment. In addition, the detection method for the printer ink anti-blocking performance is short in time consumption, and the printer does not need to be closed and placed for several days, so that the anti-blocking performance of the printer ink can be detected while the operation time is shortened.
According to some embodiments of the invention, the step of dipping the printer ink in the container with the capillary tube further comprises the steps of: the printer ink on the outside of the capillary was wiped with a wipe. It is contemplated that when the capillary tube is extended into the container to dip the printer ink, a portion of the printer ink will enter the capillary tube through the orifice at one end of the capillary tube, and a further portion of the printer ink will stick to the outer wall of the capillary tube. Because the printer ink in the outside exposes in the air, can be air-dried for a long time and glue on the outer wall of capillary, the opaque characteristic of printer ink simultaneously can shelter from the capillary finally to the printer ink in the capillary is not convenient for observe, so, dip in the printer ink in the container with the capillary and then wipe the printer ink in the capillary outside with wiping paper, when being convenient for observe, can also guarantee the clean and tidy of capillary.
According to some embodiments of the invention, the capillary is a glass-spotted capillary. Since the state of the flow of the printer ink in the capillary is to be observed, the capillary is preferably a glass spotting capillary. The glass is transparent, which is convenient for the experimenter to observe the flowing performance of the printer ink in the glass sample application capillary, and the sample application capillary is also called microlitre capillary, which is a quantitative sample application container in the thin-layer chromatography, usually with the specification of 1, 2, 3, 4, 5, 10ul, etc., and consists of a rubber dropper with a small hole at the top end, a glass tube, a rubber plug and quantitative glass capillaries which can be replaced with various specifications according to the sample application requirement. In addition to the glass capillary, there is also a platinum-iridium alloy capillary, which is generally 100 ul or 200ul in specification and is generally used as an accessory of an automatic sample applicator. The microliter capillary has the advantages of convenient use, high spotting accuracy and low price. Therefore, when the glass sample application capillary tube dips printer ink in the container, the same amount of printer ink can be quantitatively dipped, and further, the variable of the test can be conveniently controlled, so that redundant variables are eliminated, and the test result is prevented from being influenced; meanwhile, the operation of a tester is facilitated.
According to some embodiments of the invention the inner diameter of the glass deposition capillary is 0.3 mm and the tube length of the glass deposition capillary is 10 mm. According to the embodiment, the glass sample application capillary can quantitatively dip the printer ink in the container, meanwhile, the capillary has various specifications, and different specifications are suitable for different use scenes. According to the using condition of the test, the inner diameter of the selectable glass sample application capillary is 0.3 mm, the length of the glass sample application capillary is 10 mm, the inner diameter is 0.3 mm, the proper amount of printer ink can be conveniently dipped, and meanwhile, the length of the tube is 10 mm, so that the flowing performance of the printer ink can be observed. Of course, the characteristics of different printer inks are different, so that the glass sample application capillary with the proper specification can be selected according to the characteristics of the printer inks, the proper amount of the printer inks can be dipped and taken, and the detection method can be carried out more favorably and more accurate detection results can be obtained.
According to some embodiments of the present invention, the capillary tube dipped with the ink of the printer is fixed on a test tube rack, and the test tube rack is provided with more than one mounting hole. The capillary tube is dipped with ink of the printer and then is placed in the mounting hole for fixing. The test-tube rack that has a plurality of mounting holes does benefit to same management and has dipped in the capillary of printer ink, provides probably for carrying out the multiunit detection simultaneously, and multiunit testing result can reduce the contingency, still can avoid the interference of environment to lead to singly organizing detecting the error. In addition, the printer ink with different qualities placed in the test tube rack can also be compared with the anti-blocking performance of different printer inks.
According to some embodiments of the invention, the capillary is fixed for a period of at least 24 hours. After the ink is fixed and kept stand for one day, the capillary tube is inverted, then the printer ink in the capillary tube is observed, if the printer ink can still flow downwards in the capillary tube from the upper end, the anti-blocking performance of the printer ink in the state is better, and the printer ink still flows and has fluidity, so that the printer ink has good anti-blocking performance; on the other hand, if the printer ink cannot flow downward through the capillary tube from the upper end, that is, if the printer ink is at rest at the upper end of the capillary tube, the printer ink in this state has poor head clogging prevention performance, and the printer head may be clogged with the printer ink. It should be noted that the longer the fixing time of the capillary tube is, the more adverse the detection of the fluidity of the printer ink is, because the printer ink in the capillary tube is air-dried by the long-time fixing, but it is noted that the longer the fixing time is, if the printer ink still has fluidity, the better the anti-blocking performance of the printer ink is. Therefore, the fixed time of the capillary tube can be selected to be 24 hours, and according to the use time of the printer, the use rule or the use requirement of people, the common use is one day, and then the fixed time of the capillary tube can be selected to be 24 hours, so that the detection and the screening are more facilitated to obtain the appropriate printer ink.
In view of the above examples, the invention is further explained below with reference to a number of control tests for three printer inks suitable for use in a printer: it should be noted that the formulas of the three different printer inks are not consistent, so the fluidity of the three printer inks is different, and it is assumed that the three printer inks are the second printer ink, the third printer ink and the fourth printer ink, respectively, and the first printer ink is the experimental group.
Control test one: two different printer inks were selected: the anti-blocking performance of the printer ink is preliminarily judged by observing the mobility of the printer ink in a capillary after the printer ink and the second printer ink are statically placed for one day; the printer ink can then be tested for fluency by running the printer directly through the printer. Such as: the first printer ink is capable of flowing from one end of the capillary to the other end after the capillary is inverted; and the ink of the second printer stands still after the capillary tube is inverted, the result of the first verification of the comparison test shows that the ink of the first printer has better flowing performance, namely the anti-blocking performance is better, and the ink of the second printer stands still, namely the ink of the second printer has poor flowing performance, namely the plug is very serious. Subsequently, the ink of the first printer and the ink of the second printer are respectively added into the printer for carrying out nozzle printing detection, and the flowing performance of the ink of the first printer is further verified if the ink detection result of the first printer is not broken; and the number of the ink broken holes of the second printer is more than half, and the oblique jet phenomenon still exists in the nozzle printing, so that the flowability of the ink of the second printer is further verified to be very poor, and the plug is very serious.
Control experiment two: still be different printer ink, this contrast experiment can adopt three kinds of different printer ink: the anti-blocking performance of the printer ink is preliminarily judged by observing the mobility of the printer ink in a capillary after the printer ink is statically placed for one day; the printer ink can then be tested for fluency by running the printer directly through the printer. Such as: the first printer ink is capable of flowing from one end of the capillary to the other end after the capillary is inverted; when the third printer ink flows for 1 cm after the capillary is inverted, and the fourth printer ink flows for 5 cm after the capillary is inverted, the result of the preliminary verification of the comparison test II is that the first printer ink has better flowing performance, namely the anti-blocking performance is better, and when the third printer ink flows for 1 cm, the third printer ink has poor flowing performance, namely the anti-blocking performance is serious; and if the ink of the fourth printer flows for 5 cm, the ink of the fourth printer has poor fluidity, namely a slight plug phenomenon. Subsequently, adding the ink of the first printer, the ink of the third printer and the ink of the fourth printer into the printer respectively for carrying out nozzle printing detection, wherein the ink detection result of the first printer has no broken holes, and then further verifying that the flowing performance of the ink of the first printer is good; the number of the ink broken holes of the third printer is more than one third, and meanwhile, the oblique jet phenomenon still exists in the nozzle printing, so that the flowability of the ink of the second printer is further verified to be very poor, and the plug is still serious; the number of the ink broken holes of the fourth printer is only 8, and meanwhile, the oblique jet phenomenon exists in the nozzle printing, so that the flow performance of the ink of the fourth printer is further verified to be poor, and the phenomenon of slight plug exists.
According to the two comparison test embodiments, the printer ink can flow from one end to the other end in the capillary, which shows that the printer ink has good flowing performance and good anti-blocking performance. Meanwhile, when the printer ink is tested, the conditions of hole breakage, inclined spraying and plug do not occur, and the method for detecting the anti-blocking performance of the printer ink is simple and reliable and does not need to pass through a printer nozzle, so that the possibility of damaging the nozzle is reduced. In addition, the control experiment also shows that the larger the distance that the printer ink flows in the capillary tube, the better the flow performance, and the better the anti-blocking head performance.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
