Description

Technical Field

[0001] The utility model relates to the technical field of folding machines, in particular to a paper loading structure for folding machines. Background Art

[0002] Folding machines are modern printing equipment that have emerged along with the modern printing industry. Printing industry processing is usually divided into book, periodical and newspaper processing and packaging processing. Folding machines can be mainly used to fold various sizes and thicknesses of paper within the design range. They are suitable for large-scale folding of fast printing centers, production enterprises, official documents and business letters.

[0003] After searching, it was found that the application number is CN202320962006.1, and the name is a feeding and pressing device for a folding machine. The application proposed the existing application number CN201820466611.9, and the patent name is a Chinese utility model patent for a folding machine. The patent has the problem that it does not have an elastic adjustment function. When the number of papers is reduced, the pressure of the pressing wheel on the paper will inevitably decrease or even not contact each other, that is, the pressing effect cannot be achieved, affecting the paper feeding effect of the paper table folding machine. The staff needs to adjust the inclination of the pressing wheel swing arm according to the changes in the paper; in addition, after a stack of papers is loaded, the staff needs to move the paper back to the machine and adjust the position of the bracket back and forth so that the pressing mechanism is aligned with the edge of the paper. The operation is cumbersome and inefficient. The elasticity of the spring can ensure that the pressure wheel presses the paper in real time when the paper continues to decrease, thereby ensuring the paper feeding efficiency of the folding machine. At the same time, the structure is simplified. When adjusting the position of the pressure wheel relative to the paper, only two steps are required, namely, lifting the rocker and moving the slider, to adjust the position of the pressure wheel. It is convenient and quick. However, when the folding machine is actually working, the elastic potential energy of the spring is in excess. Therefore, it is difficult for the pressure wheel to separate from the paper. This application needs to adjust the pressure wheel every time paper is loaded, which is not only inconvenient, but also increases the operating steps and is more cumbersome. At the same time, there will be friction when the paper moves, and the friction generates static electricity. The adsorption effect generated by static electricity will not only affect the paper feeding one by one, but also affect the subsequent folding process. Further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
