Abstract

The invention provides a chain phase adjusting mechanism which comprises two symmetrically-arranged chain tensioning components. Guide rails and driving components are arranged on the outer sides of the chain tensioning components, the guide rails are installed on external equipment, tensioning plates of the chain tensioning components can be driven by adjusting components to move left and right along the guide rails, and the driving components are in signal connection to a controller. A driven paper conveying chain wheel and a driving paper conveying chain wheel are arranged at the upper end and the lower end of each chain tensioning component correspondingly, wherein a transmission structure is formed by the driven paper conveying chain wheel, the driving paper conveying chain wheel and the chain tensioning component. A gripper row and a guide plate are installed between the two chain tensioning components. The chain phase adjusting mechanism can be used for adjusting the breadth of an ink-jet digital printing machine, and the corresponding chain phase is changed through an adjusting motor of the chain phase adjusting mechanism according to the difference value of breadth adjustment, so that the relative position of a closed-loop paper path of the whole digital printing machine is not changed, and the accuracy of paper delivery is ensured.

Description

technical field [0001] The invention belongs to the field of printing machinery, in particular to a chain phase adjustment mechanism. Background technique [0002] The paper preset function of inkjet digital printing: it means that before the printing machine replaces paper with different specifications and sizes, the paper size specifications to be used are input into the printing machine operating system, and the digital printing machine automatically adjusts the relevant mechanisms of the platform according to the input data, including paper feeding Presetting mechanism for section, delivery section and turning section. The preset mechanism of the paper part and delivery part is basically the same as the paper preset mechanism on the offset printing machine. However, the existing printing equipment cannot adjust the format, and can only print with fixed specifications, and there is no phase adjustment mechanism. Therefore, it is urgent to develop a phase adjustment mechan...
