There are flat die-cutting machines, round die-cutting machines, and round die-cutting machines. Flat die-cutting machines are currently the most widely used and common type, and are also produced by domestic and foreign manufacturers. The most models. Domestic manufacturers include Xinchuan Machinery, Shanghai Yahua, Tangshan Yuyin, Beiren Group Company, Henan New Machinery Group, Beijing Shengli Weiye Printing Machinery Co., Ltd.; foreign manufacturers include Swiss BOBST, German IMG, Japanese ASAHI, and American Standard Paper Box Machinery Company, Spanish IBERICA, Korean YoungShin Machinery Co., Ltd., Japanese IIJIMA and other manufacturers. The flat die cutting machine can be used for various types of die cutting. It can not only manual paper feeding, semi-automatic die cutting, but also fully automatic high-speed linkage die cutting; it can not only die cut corrugated cardboard, cardboard, and self-adhesive, but also Die cutting rubber, sponge, metal sheet, etc. The vertical flat die-cutting machine is commonly known as the tiger's mouth. It is said to have a biting action similar to that of a mouth when working, and it is said to be unsafe and easy to hurt people, hence the name. In any case, it vividly illustrates the working characteristics of the vertical flat die cutting machine. The structure of the vertical flat die-cutting machine is mainly divided into two parts: the fuselage and the press frame. The die-cutting plate is installed on the fuselage. There are two types according to their action modes: single pendulum and double pendulum. The so-called single swing type means that during die-cutting, the press frame swings and the machine body does not move (that is, the plate table does not move). The plate table and the lower part of the press frame contact first, then the upper part. When the die-cutting ends, the upper part leaves first, and the lower part leaves last. , such that the force time is different and the force is uneven, so it is used less and less and is gradually eliminated. The double-swing type means that during die cutting, both the machine body and the press frame move. Before contact, the press frame plate and the plate table are parallel, and the contact form between them is parallel movement, so the pressure is large and uniform. Most of the vertical flat die-cutting machines produced belong to this type. Vertical flat die cutting machines can be divided into two types: semi-automatic and fully automatic according to the degree of automation. At present, the vertical flat die-cutting machines (Tiger Mouth) produced in China are mainly semi-automatic. Die-cutting is done by machine, and paper feeding and paper delivery are done manually. Since production quality and efficiency are related to the operator's proficiency and are prone to safety accidents, the United States and other developed countries have banned the use of this equipment
