Embodiment 1

[0049] Embodiment 1 of the present invention provides a printing device for testing liquid properties. The tested liquid properties include: at least one of the number of satellite dots of ink dots, the printing straightness of ink dots, and the uniformity of ink dot size. Of course, in order to obtain More accurate liquid performance can also include other liquid test performance, such as fluency, etc., and the specific test that needs to be applied is not limited here. All parameters that can characterize the performance of printing liquids are covered by the protection of the present invention. within range. Specifically, the liquid performance test is to control the dot images formed by spraying a single row of nozzles on the printing medium once, and observe the corresponding characteristics of each dot image to obtain the performance of the ink. In order to verify the corresponding performance of the ink under various ejection volumes, different ejection volumes are used...

Embodiment 2

[0141] Embodiment 2 of the present invention is improved on the basis of Embodiment 1, combining figure 2 as well as Figure 11 As shown, the liquid observation mechanism 5 is specifically provided, and further, the liquid observation mechanism 5 includes: a collection part 53, and the collection part 53 is used to collect the liquid droplet images ejected by the nozzles of several spray heads within a preset time; the collection of the collection part 53 The scope covers at least the jetting surface of the nozzle, and the collection part 53 adopts a camera, and its collection range is spread out from the axis of the collection part 53 to the surroundings, and presents a collection angle from a side view, that is to say, the method adopted in this application is to collect The image captured by section 53 is the liquid starting from the nozzle leaving the spray head.

[0142] to combine Figure 14 as well as Figure 11 As shown, the liquid observation mechanism 5 includes ...

Embodiment approach 2

[0163] The second aspect of the present invention provides a printing device control method, which is used to control the printing device described in any one of the above, combined with Figure 17 As shown, the method includes:

[0164] Controlling the first type of nozzle in the at least two types of nozzles to be located in the zero adjustment zone;

[0165] Perform zero adjustment processing on the first type of nozzle;

[0166] After the first type of nozzle is adjusted to zero, control the first type of nozzle to move to the printing area to eject the liquid to the first designated area of ​​the printing medium;

[0167] After the first type of nozzle is sprayed, control the second type of nozzle to move to the zero adjustment area;

[0168] After the second type of nozzle is zero-adjusted, the second type of nozzle is controlled to move to the printing area to eject liquid to a second designated area of ​​the printing medium.

[0169] In the present invention, the pr...

Abstract

The invention belongs to the technical field of printing, solves the technical problem that printing equipment in the prior art is small in tested liquid volume range, and provides printing equipment for testing liquid performance and a control method thereof. The equipment comprises a printing trolley; the printing trolley comprises at least two spray heads, where the spray heads spray liquid towards a printing medium in sequence, and at least part of the spray liquid amount ranges capable of being sprayed by the spray heads do not coincide; the cross beam, where the equipment is at least provided with a zeroing area and a printing area which are independent from each other in the length direction of the cross beam, when the printing trolley is located in the printing area, the spray head sprays liquid to the printing medium, and when the printing trolley is located in the zeroing area, the spray head to be sprayed with liquid in the printing trolley is zeroed; the first driving mechanism that drives the printing trolley to reciprocate between the zeroing area and the printing area, wherein after the current liquid spraying nozzle is located in the printing area and sprays liquid to the printing medium, the first driving mechanism drives the printing trolley to the zero setting area, and zero setting is conducted on the next to-be-sprayed nozzle.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing device for testing liquid properties and a control method thereof. Background technique [0002] Printing is to spray liquid (such as ink, coating, treatment liquid, etc.) on the printing medium by jetting, and form patterns, characters, etc. on the printing medium, so as to decorate and mark the printing medium. During the printing process, it is necessary to set appropriate ejection parameters (such as waveforms) so that the liquid forms a precise and stable printing pattern on the surface of the printing medium. When setting appropriate ejection parameters, it is usually necessary to test the performance of the liquid (such as ink accuracy, ink splashing, fluency and other performance tests), and set appropriate ejection parameters according to the performance of the liquid, so that the accuracy can be formed during the printing process. Higher, better-performing ...
