Description

Technical Field

[0001] The utility model relates to a paper storage mechanism for automatically changing rolls of roll paper without stopping the machine, belonging to the technical field of roll paper storage. Background Art

[0002] Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then the printing press applies ink to the places where the text and image are on the printing plate, and then directly or indirectly transfers it to the paper roll, thereby replicating the same printed product as the printing plate.

[0003] Replacing paper rolls in a printing press is an indispensable part of the printing process. Existing printing presses need to slow down or stop for roll changing operations because there is no paper storage or the paper storage amount is small. Some paper storage mechanisms with large paper storage amounts are heavy, large in size, and run unsteadily, which affects the production speed and even has a great impact on transportation, which is not conducive to environmental protection and energy saving.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
