Embodiment Construction

[0019] In the embodiment of the present invention, the adjustment device includes a pin shaft connected to one end of the spray head, a double eccentric sleeve connected to the pin shaft, and a hinged link connected to the double eccentric sleeve at one end. The hinged connecting rod drives the double eccentric sleeve to rotate, the double eccentric sleeve drives the pin shaft to rotate, and the pin shaft drives the nozzle to move. Since there is no friction between the hinged connecting rod, the double eccentric sleeve, the pin shaft and the nozzle, there is no sliding friction damping, and no crawling phenomenon occurs, thus improving the accuracy of adjustment.

[0020] In this embodiment, the movement of the spray head in the X direction and / or the Y direction is realized through the double eccentric sleeves, so as to adjust the position of the spray head in the X direction and / or the Y direction.

[0021] see figure 2 In this embodiment, the adjusting device includes a ...

Abstract

The invention discloses an adjusting device for improving adjusting accuracy. The device comprises a pin shaft connected with the first end of a spray head, double eccentric sleeves connected with the pin shaft, and a hinged connecting rod, wherein the first end of the hinged connecting rod is connected with the double eccentric sleeves; the hinged connecting rod is used for driving the double eccentric sleeves to rotate; the double eccentric sleeves are used for driving the pin shaft to rotate; and the pin shaft is used for driving the spray head to move.

Description

technical field [0001] The invention relates to the field of machinery and printing, in particular to an adjusting device. Background technique [0002] With the continuous development of inkjet printing technology, it has now successfully entered the era of high-speed printing, and experts in the industry continue to explore and research. There are many nozzle adjustment methods in the prior art, most of which use thread deceleration method or slope deceleration method, or a combination of both to realize the adjustment of the nozzle position. [0003] see figure 1 As shown, the position adjustment includes position adjustment in two directions, X direction adjustment (or nozzle splicing adjustment) and Y direction adjustment (or nozzle parallelism adjustment). X-direction adjustment refers to: when multiple nozzles are spliced ​​with each other, the projection distance of the connected nozzles between two adjacent nozzles along the vertical direction of the substrate mov...
