One cylinder is equivalent to the impression cylinder, and pressure is applied during die-cutting; the other is the cylinder die. There are two types of roller cutters: wood and metal. The former is mainly used for die-cutting very thick corrugated cardboard, while the latter has metal drum cutters processed by chemical corrosion or electronic engraving, which are mainly used for die-cutting of self-adhesive labels and trademarks. , There is also a metal drum knife die mainly used for medium and high-grade long-line products, in the form of pressing or shearing.
Circular Flattening Die Cutting Machine
The application of circular flattening die-cutting machine in the market is seldom, and there are no professional manufacturers in China, so I will not repeat them here.
Flat die-cutting machine
Flat die-cutting machine is the most widely used and most common type at present, and it is also the most widely used by domestic and foreign manufacturers model.
Vertical flat die-cutting machine, commonly known as the tiger's mouth, is named because it is similar to the bite action of the mouth when it is working, and it is unsafe and easy to hurt people when it is working. In any case, the working characteristics of the vertical flat die-cutting machine are vividly illustrated. The vertical flat die-cutting machine is mainly divided into two parts: the fuselage and the pressing frame. The die-cutting table is installed on the fuselage. There are two types according to the way it moves: single swing and double swing. The so-called single pendulum type means that when the die cutting, the press frame swings, the body does not move (that is, the plate table does not move), the plate table and the press frame are in contact with the lower part first, and then the upper part contacts. When the die cutting ends, the upper part leaves first, and the lower part leaves after , so the force time is different and the force is uneven, so the use is less and less, and it is gradually eliminated. Double pendulum means that when die cutting, both the machine body and the press frame move. Before the contact, the press frame platen 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 flatbed die-cutting machines produced are of 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 machine (tiger mouth) produced in China is mainly semi-automatic, the die-cutting is done by machine, and the paper feeding and delivery are done manually. Since the production quality and production efficiency are related to the operator's proficiency and are prone to safety accidents, developed countries such as the United States have banned the use of this equipment.
