Embodiment Construction

[0019] The adjustment device in this embodiment of the present invention includes: a first eccentric sleeve connected to the first pin shaft, a first hinged link connected to the first eccentric sleeve, a protection component connected to the other end of the spray head, and a second pin connected to the protection component Shaft, the second eccentric sleeve connected with the second pin shaft and the second hinge link connected with the second eccentric sleeve. The hinged connecting rod drives the eccentric sleeve to rotate, the 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 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 two ecce...

Abstract

The invention discloses an adjusting device for improving adjusting accuracy. The device comprises a first pin shaft connected with one end of a spray head, a second pin shaft connected with the other end of the spray head, a first eccentric sleeve connected with the first pin shaft, a second eccentric sleeve connected with the second pin shaft, a first hinged connecting rod connected with the first eccentric sleeve and a second hinged connecting rod connected with the second eccentric sleeve; the first hinged connecting rod and the second hinged connecting rod are respectively used for driving the first eccentric sleeve and the second eccentric sleeve to rotate; the first eccentric sleeve and the second eccentric sleeve are respectively used for driving the first pin shaft and the second pin shaft to rotate; and the first pin shaft and the second pin shaft are respectively 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...
