Description

Technical Field

[0001] The utility model belongs to the technical field of nozzle printing test, and particularly relates to a printing test tooling assembly for nozzles of multiple models. Background Art

[0002] An inkjet printer is a type of printer that turns colored liquid ink into fine particles through nozzles and sprays them on printing paper to form patterns or words. With the continuous development of industrialization, the application scenarios of domestic digital inkjet printers are changing with each passing day. In order to adapt to different application scenarios, various models of nozzles have emerged in the market. During the production and processing of nozzles, corresponding printing test tooling assemblies are usually required to install and debug the nozzles, so as to test and adjust the nozzles.

[0003] During the test of traditional inkjet printer nozzles, it is usually necessary to redesign the nozzle assembly components of the inkjet printer according to the nozzles, which makes the product cycle from the test to mass production of the inkjet printer nozzle longer. At the same time, the redesign of the nozzle assembly components also increases the R & D and test costs of the inkjet printer nozzle.

[0004] As disclosed in the Chinese utility model patent with the patent number: CN208584911U, a printer nozzle test device includes a feeding mechanism, an inkjet printing mechanism, and a control device. The feeding mechanism includes a conveying frame and a first fixing frame connected to the conveying frame. The inkjet printing mechanism includes a second fixing frame, a plurality of ink cartridges, a supply ink path connected to the ink cartridges, a circulating ink path, and a negative pressure detection pipeline. The control device includes a processor, a DC power supply board, and a PLC controller; the second fixing frame is connected to the first fixing frame, a plurality of ink cartridges are fixedly installed on the top of the second fixing frame, a nozzle fixing panel is provided at the bottom of the second fixing frame, a plurality of nozzles are installed on the nozzle fixing panel, the ink cartridges are connected to the nozzles through ink tubes, the processor is connected to the DC power supply board, the DC power supply board is respectively connected to the PLC controller and the control board of the nozzle, and the PLC controller is respectively connected to a supply ink pump, a circulating pump, and a negative pressure sensor. The utility model can realize the test of at least two models of nozzles, with convenient test, low test cost, strong practicability, and easy to popularize.

[0005] However, it can be seen from the content recorded in the specification and the specification drawings that a printer nozzle test device disclosed in this application cannot disassemble and assemble the nozzle to be tested conveniently according to the different nozzle models, resulting in poor high-efficiency convenience for testing nozzles of multiple models.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a printing test tooling assembly for nozzles of multiple models.
