Abstract

The invention provides a spray head adjusting device. The spray head adjusting device comprises a fixing plate, a mounting plate and an adjusting mechanism, wherein the fixing plate is installed on a rack of ink jet printing equipment in a matching manner; the mounting plate is provided with a spray head of the ink jet printing equipment in a matching manner; and the adjusting mechanism is connected with the fixing plate and the mounting plate and adjusts the horizontal rotation angle of the mounting plate relative to the fixing plate in a matching manner. The invention provides ink jet printing equipment, comprising the spray head adjusting device. The invention provides a spray head adjusting method. The spray head adjusting method comprises the following steps: due to the adjustment of the adjusting mechanism, the mounting plate can rotate horizontally relative to the fixing plate, wherein the fixing plate is installed on the rack of the ink jet printing equipment, and the spray head of the ink jet printing equipment is installed on the mounting plate. According to the invention, the spray head can be adjusted and controlled conveniently, and the printing quality is improved.

Description

technical field [0001] The present invention relates to the field of printing, in particular, to a nozzle adjustment method and device, and an inkjet printing device. Background technique [0002] Inkjet technology has been widely used at present. Limited by the low DPI of a single nozzle, in order to achieve a fine and beautiful printing effect, the current nozzles are arranged in a "saber angle". The so-called saber angle, that is, the nozzle is not perpendicular to the moving direction of the substrate, but has an acute angle with the moving direction of the substrate, and the time of inkjet of each nozzle is controlled to ensure that each nozzle prints on the same straight line. This method has very strict requirements on the saber angle. as attached figure 1 Shown, DPI A for native DPI, DPI B for the actual print DPI. [0003] DPI B =n×25.6 / L1=n×25.6 / (L×tan(π / 2-a))=DPI A ×tan(π / 2-a) [0004] Among them, n is the nozzle number of the nozzle; L1 is the printing w...
