Paper feeding door locking mechanism and printing machine using same

Abstract

The invention provides a paper feeding door locking mechanism and a printing machine using the same. The paper feeding door locking mechanism comprises two limiting pieces, a pushing piece and a locking assembly, the two limiting pieces are rotatably arranged on a bottom plate, the two limiting pieces are arranged to be capable of approaching or leaving each other through rotation, the two limiting pieces jointly form a limiting hole with an opening in one end when being far away from the first position, and can close the opening when being close to the second position; the pushing piece can move into the limiting hole from the opening, and the two limiting pieces are simultaneously pushed to rotate to the second position towards a direction close to each other; the locking assembly is used for locking the two limiting pieces at the second position when the two limiting pieces rotate to the second position; and locking of the two limiting pieces is relieved, and meanwhile, the two limiting pieces are reset to the first position. By means of the paper feeding door locking mechanism, the problems that the locked paper feeding door cannot deviate due to collision, vibration and other reasons, and the position of a seal is not accurate are solved.

Description

technical field [0001] The invention relates to the technical field of office automation, in particular to a paper-feed door locking mechanism and a printing machine using the paper-feed door locking mechanism. Background technique [0002] In daily management work, the traditional seal management method is to assign managers to be responsible for the use and protection of the seal. This seal management method not only has high work efficiency and operating costs, but it is also difficult to eliminate violations in the daily seal management process. Seal management regulations, acts against the normal will occur, and once such a situation occurs, it will often cause heavy losses to the company or unit. For solving the problems referred to above, the printing machine that can carry out stamping automatically is more and more subject to people's attention. [0003] A traditional printing machine usually has a paper feed door, which is used to load the paper to be stamped, and...
