Description

A paper receiving mechanism of a printing machine

technical field

The invention relates to the field of printing machines, in particular to a paper delivery mechanism of a printing machine.

Background technique

The printing machine is generally composed of plate loading, ink application, embossing, paper delivery and other mechanisms. The working principle of the printing machine is: firstly, the text and image to be printed are made into a printing plate, installed on the printing machine, and then manually or by the printing machine. The ink is applied to the place where there are characters and images on the printing plate, and then directly or indirectly transferred to the paper, so as to reproduce the same printed matter as the printing plate. The delivery mechanism is an important part of the printing machine. The existing There are some deficiencies in the paper delivery device. The printed paper comes out of the paper outlet of the printing machine too fast, and the high-speed moving paper collides with the cardboard, which will easily cause paper wrinkles, damage and skew. At the same time, the existing The paper delivery device needs to transfer the paper after the paper has accumulated to a certain height. At this time, the machine needs to be suspended, and the printing machine cannot work continuously. Move it down and re-place a new delivery board on the lifting plate. When re-installing the delivery board, it is difficult to put it manually, and the difficulty of placement is increased due to the blocking of the cardboard. The workload of the staff is heavy, the labor intensity is high, and the work efficiency is low. . The existing paper delivery devices are all fixed on the ground and cannot be moved, which is very inconvenient when the paper delivery device needs to be moved. Aiming at the above technical problems, the present invention discloses a continuous paper delivery mechanism of a printing machine, which has the advantages of continuous and uninterrupted paper delivery, high flatness of collected paper, low labor intensity of staff, high paper delivery efficiency, and the ability to move. .

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a paper delivery mechanism for a printing machine to solve the problem of paper wrinkling, damage and skew caused by the collision between high-speed moving paper and the paper stopper in the prior art. After the paper has accumulated to a certain height, it is necessary to stop the machine to transport the paper, and it needs manpower to carry. The labor intensity of the staff is high and the work efficiency is low. Installed on the ground, immovable and other technical issues. The invention has the advantages of continuous and uninterrupted paper delivery, high flatness of the collected paper, low labor intensity of staff, high paper delivery efficiency, and the ability to move.

The present invention is realized through the following technical solutions: the invention discloses a paper delivery mechanism of a printing machine, which includes a frame, a paper output device, a paper feeding device and a paper receiving device, and the paper output device, the paper feeding device and the paper receiving device are all installed On the frame, the paper feeding device is located between the paper output device and the paper receiving device.
