Types of die-cutting machines:
Die cutting machines are mainly divided into three types according to the different forms of stamping: circular pressing, circular pressing, and flat pressing. According to the placement form of the template, it can be divided into two types: vertical and horizontal. According to the degree of automation, there are two options: manual (semi-automatic) and automatic. From a functional perspective, in addition to die-cutting, there is also a stamping function called hot stamping die-cutting machine, and some have an automatic waste cleaning function called waste cleaning die-cutting machine.
1. Circular die-cutting machine
The characteristics of circular die-cutting machines are line contact, low die-cutting pressure, and high production efficiency. They can be connected to printing equipment such as offset printing machines, flexographic printing machines, and gravure printing machines for online die-cutting, so their application range is relatively wide. A drum is equivalent to an imprinting drum and applies pressure during die-cutting; The other one is the drum knife mold. There are two main types of drum knife molds: wood and metal. The former mainly molds thick corrugated cardboard, while the latter has metal drum knife molds processed using chemical erosion or electronic carving methods, mainly used for die-cutting self-adhesive labels and trademarks. There is also a metal drum knife mold mainly used for medium to high-end long line products, using pressure cutting or shear type forms.
2. Circular flattening die cutting machine
At present, the application of circular flattening die-cutting machines in the market is very limited, and there is no professional manufacturer domestically, so it will not be elaborated here.
3. Flat die-cutting machine
Flat die-cutting machine is currently the most widely used and widely used type, and it is also the model with the most manufacturers at home and abroad. There are manufacturers such as Shanghai Yahua, Tangshan Yuyin, Beiren Group Company, Henan Xinji Group, and Beijing Shengli Weiye Printing Machinery Co., Ltd. in the domestic market; Abroad, there are manufacturers such as Swiss BOBST, German IMG, Japanese ASAHI, American Standard Carton Machinery Company, Spanish IBERICA, South Korean YoungShin Machinery Co., Ltd., Japanese IIJIMA, and others. The flat press die-cutting machine can be used for various types of die-cutting, which can be manually fed and semi-automatic die-cutting, as well as fully automatic high-speed linkage die-cutting; It can not only die cut corrugated cardboard, cardboard, adhesive, but also rubber, sponge, metal sheet, etc.
The vertical flat pressing die cutting machine, commonly known as the tiger mouth, is named for its bite like action during operation and for its unsafe and easily injurious operation. Anyway, it vividly illustrates the working characteristics of the vertical flat pressing die cutting machine. The vertical flat pressing die cutting machine is mainly divided into two parts in terms of structure: the body and the press frame, and the die cutting plate platform is installed on the body. There are two types of movements according to their movements: single pendulum and double pendulum. The so-called single pendulum type refers to when die-cutting, the pressure frame swings, and the body does not move (i.e. the plate platform does not move). The plate platform first contacts the lower part of the pressure frame, and then the upper part contacts. At the end of die-cutting, the upper part leaves first, and the lower part leaves later. This way, the force is applied for different times and unevenly, resulting in less and less use and gradually becoming obsolete. Double pendulum type refers to the action of the machine body and the press frame during die cutting. Before contact, the press frame platen and the platen table are parallel, and the contact form between them is Parallel transport, so the pressure is large and average. Most of the vertical flat die-cutting machines currently produced belong to this type. Vertical flat press die-cutting machines can be divided into two types based on the degree of automation: semi-automatic and fully automatic. The vertical flat pressing dies currently produced domestically
