Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a paper printing positioning device and a printing machine. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). Its working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied manually or by the printing press to the areas of the printing plate containing the text and images. The ink is then transferred directly or indirectly to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thereby reproducing a printed product identical to the printing plate.

Then the motor 301 is started, the lead screw 302 rotates, and the moving block 303 moves the positioning frame 4 towards the printing mechanism, which facilitates the positioning of the paper and avoids the difficulty of positioning the paper during the printing process.
