Base plate assembly and digital printing apparatus

Abstract

The invention provides a base plate assembly and a digital printing apparatus. The base plate assembly includes a substrate; a base plate attached to the upper surface of the base plate, wherein the first end of the base plate is rotatably connected with one end of the substrate; a regulating member rotatably installed on the other end of the substrate and cooperating with the base plate in orderthat the base plate can rotate to any position on the substrate; and a locking member cooperating with the regulating member in order that the regulating member and the substrate can be mutually pressed and locked, wherein when the regulating member and the substrate are mutually pressed and locked, the regulating member and the base plate are buckled and the base plate can be locked at any position. In the technical solution, the position of the base plate can be detected by using the regulating member, and the regulating member can be pressed on the substrate by using the locking member after the position is detected, and then the base plate can be locked by means of the buckling of the regulating member and the base plate. The locking manner avoids any movement phenomenon in a locking process so as to precisely lock the base plate to the position detected by the regulating member.

Description

Technical field [0001] The present invention relates to the field of digital printing equipment, and more specifically, to a bottom plate assembly and digital printing equipment. Background technique [0002] In wide-format digital printing equipment, the problem of overprinting between colors is often involved, so when printing. It is necessary to rotate one of the color groups to track the printing position of the other color group, and lock it after locating the position to avoid the phenomenon of color group shifting during printing. In the related art, the locking of the color group after the correct position is realized by screws, that is, the color group is locked on a fixed object with screws to prevent it from running out. However, this locking method In the specific process of tightening the screws, the rotation of the screws will cause the position of the bottom plate to change in the circumferential direction, so that the locked position is not the correct position a...

Problems solved by technology

In related technologies, the locking of the color group after finding the correct position is all realized by screws, that is, the color group is locked on a certain fixed object by screws to prevent it from moving. However, this locking method , in the process of tightening the screws, the rotation of the screws will change the position of the bottom plate in the circumferential direction, so that the locked position is not the correct position after the bottom plate is aligned, thus reducing the quality of the printed matter
