Embodiment 1

[0039] Embodiment 1 of the present invention provides a printing device for delay switching between nozzles to test liquid performance, which solves the technical problem of instability in the multi-nozzle switching system in the prior art, and is used to switch at least two types of nozzles with different sprayable liquid volume ranges. The nozzle sprays the liquid in a predetermined sequence to test the performance of the liquid, which has the advantages of stably spraying the liquid and accurately testing the performance of the liquid. Wherein, the tested liquid performance includes: at least one of the number of satellite dots of the ink dot, the printing straightness of the ink dot, and the uniformity of the ink dot size. Of course, in order to obtain more accurate liquid performance, other liquid test performances may also be included. For example, fluency, etc., the specific tests that need to be applied are not limited here, and any parameters that can characterize the ...

Embodiment 2

[0104] The second aspect of the present invention provides a control method of a printing device for delay switching between nozzles to test liquid performance; specifically, it is used for controlling the printing device involved in any one of the first embodiment. Specifically, combine figure 1 , the printing device includes: at least two types of nozzles with different sprayable liquid volumes, at least two types of nozzles include: a first type of nozzle 21 and a second type of nozzle 22; a first nozzle driving board corresponding to the first type of nozzle 21; The second nozzle drive board corresponding to the two types of nozzles 22; the main control board; combined Figure 14 , the control method includes: S1. After the main control board controls the first nozzle driving board to drive the first nozzle to spray liquid, control the first nozzle driving board to send a feedback signal to the main control board; S2. After the main control board receives the feedback sign...

Abstract

The invention belongs to the technical field of printing, solves the problems that a printing device is small in tested liquid volume range and large in limitation, and provides a printing device for testing liquid performance through delay switching between nozzles and a control method of the printing device. The printing device is used for switching at least two spray heads with different spray liquid amount ranges to spray liquid according to a preset time sequence so as to test liquid performance, the printing device comprises at least two spray head driving plates, the number of the spray head driving plates is consistent with the types of the spray heads, and each spray head driving plate is used for correspondingly driving one spray head to spray liquid; a main control board; one end of the time-delay switching circuit is connected with the main control board, and the other end of the time-delay switching circuit is connected with one of the at least two nozzle driving boards. The device has the advantages that two or more nozzles can be driven at the same time, the spraying volume range is wide, the applicability is high, and liquid performance testing is accurate.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing device and a control method thereof for testing liquid performance by delay switching between nozzles. Background technique [0002] Printing is a technology that uses jetting to spray liquid (such as ink, coating, treatment liquid, etc.) on the printing medium to 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 du...
