Paper supply mechanism used for printing machine

Abstract

The invention discloses a paper supply mechanism used for a printing machine, and relates to the technical field of printing machine auxiliary devices. The paper supply mechanism comprises the printing machine and further comprises a paper supply mechanism body. The paper supply mechanism body comprises guide rails symmetrical to each other. An installation base is arranged beside one guide rail.A rotation motor is fixedly installed on the installation base. A rotating shaft is arranged on the rotation motor. Installation blocks are arranged on the rotating shaft. An arm rod is fixedly installed on each installation block. A limiting rod is arranged on each arm rod. Arc-shaped limiting plates are arranged on the two sides of each guide rail. An arc-shaped groove is formed in each arc-shaped limiting plate. The limiting rods are connected in the arc-shaped grooves in a sliding manner. According to the paper supply mechanism, by arranging the rotation motor, the rotating shaft, the armrods, the arc-shaped limiting plates and the limiting rods, the arm rods can be connected to the rotating shaft in a rotating manner; and the limiting rods are connected in the arc-shaped limiting plates in the sliding manner, the rotation motor is controlled to make a scroll-carrying roller conveyed to the position of a paper inlet to work, and the problem that because at present, time and laborare consumed and collision is likely to be caused during manual replacement, the machine and paper on the scroll-carrying roller are damaged is solved.

Description

technical field [0001] The invention belongs to the technical field of printing machine auxiliary equipment, and in particular relates to a paper feeding mechanism for a printing machine. Background technique [0002] A machine for printing text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, then apply the ink to the place with the text and image on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Print onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass, and ceramics to reproduce the same print as the printing plate. The invention and development of the printing press played an important role in the spread of human civilization and culture. ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a paper feeding mechanism for a printing machine. By setting a rotating motor, a rotating shaft, an arm rod, an arc-shaped limit plate and a limit rod, the arm rod is rotatably connected to the rotating shaft, and the limit rod is slidably connected In the arc-shaped limit plate, the tape roll is transported to the paper inlet for work by controlling the rotating motor, avoiding the risk of damage to the paper and the machine caused by manual handling, saving time and effort, and solving the problem of time-consuming manual replacement. Power-intensive and easy to cause collisions, damage to the machine and the paper on the tape roll
