Description
Technical Field
[0001] The utility model relates to the technical field of paper printing, and particularly to an anti-curling mechanism. Background Technique
[0002] Printing is a technology that transfers the original manuscripts such as characters, pictures, photos, anti-counterfeiting, etc. to the surfaces of materials such as paper, textiles, plastics, leather, PVC, PC, etc. through processes such as plate making, inking, and pressing, and batch-replicates the content of the original manuscripts. Printing is the process of transferring the approved printing plate to the printing substrate through a printing machine and special ink. A printing machine is a machine for printing characters and images. Modern printing machines generally consist of mechanisms such as plate loading, inking, impression, and paper feeding. First, the characters and images to be printed are made into printing plates and installed on the printing machine, and then the ink is applied to the places with characters and images on the printing plate by manual or the printing machine, and then directly or indirectly transferred to paper or other printing substrates, thereby replicating the same printed matter as the printing plate. The invention and development of printing machines play an important role in the dissemination of human civilization and culture.

Therefore, it is necessary to reverse the roll of the paper to achieve the purpose of flat paper. However, the bending degree of each paper roll is different, so it is necessary to adjust the angle of the equipment to control the degree of reverse bending required. When the existing anti-curling mechanism is in use, due to the long length of the roller, it is easy to make the pressure received by the roller uneven during work, affecting the use effect of the roller.
