近年来,全国各地生产使用的信函过戳机很多,各类型机的分离机构虽然外形各种各样,但由于要求成本低,结构简单,都采用“磨擦分离”的结构。所谓磨擦分离,就是利用不同材料对运行信件产生的磨擦力不同来实现分离。磨擦分离的示意图见图1。其中挡板、阻尼板均可上、下调节,有的机器还可以作角度上的调节。其目的是使过戳机适应信函或单据 In recent years, a lot of letters and stamps have been produced and used all over the country. Although various types of machines have different shapes, they all adopt the structure of “friction separation” due to the low cost and simple structure. The so-called friction separation, is the use of different materials on the operation of the letter generated friction to achieve separation. Schematic diagram of friction separation shown in Figure 1. One baffle, damping plate can be up and down regulation, and some machines can also be adjusted for the angle. The purpose is to make the stamp machine fit letters or documents
