Description
Technical Field
[0001] This utility model relates to a conveying device, and more particularly to a cam-lifting conveying mechanism. Background Technology
[0002] In the field of paper handling and conveying, cam-lifting paper conveying mechanisms are a common mechanical device widely used in various automated equipment, such as printers and copiers. These mechanisms achieve precise paper positioning and conveying through the coordinated work of cams and driven components, playing a crucial role in improving equipment efficiency and automation levels. However, with the continuous growth of application demands, existing cam-lifting paper conveying mechanisms have gradually revealed some significant problems, which largely limit their further application and advancement.
[0003] First, inaccurate feeding position is a major challenge faced by existing cam-lifting paper feed mechanisms. This problem is particularly evident in high-speed, high-precision paper handling equipment, which can lead to malfunctions such as uneven paper stacking, paper jams, or misaligned printing, seriously affecting equipment stability and user experience.
[0004] Secondly, existing cam-lifting paper conveying mechanisms often suffer from rigid collisions during operation. These collisions not only generate noise but, more importantly, can easily cause physical damage to the paper, such as scratches, wrinkles, or even tears. This damage is particularly unacceptable for thin paper, special paper materials, or paper requiring high flatness, severely impacting product quality and appearance.
[0005] In summary, existing cam-lifting paper conveying mechanisms have significant shortcomings in terms of conveying position accuracy and reducing paper damage, failing to meet the ever-increasing demands for paper processing precision and quality. Therefore, there is an urgent need for a novel cam-lifting paper conveying mechanism to solve these problems, improve the accuracy and reliability of paper conveying, reduce physical damage to the paper, and meet the high requirements of modern automated equipment for paper processing.
