What are the types of paper processing die cutting machine?

Abstract: Die cutting machines are widely used in post press packaging processing, with a wide variety and powerful functions. What types of die cutting machines are there? Die cutting machines are mainly divided into three types: Rotary Die Cutting Machine, Rotary Flatbed Die Cutting Machine, and Flatbed Die Cutting Machine according to the different imprinting forms.

[Types of die cutting machines] Talk about the types of die cutting machines. What types of die cutting machines are there?

The die cutting machine is mainly used for die cutting, creasing and cold pressing of trademarks, cartons, greeting cards, etc. in the paper product packaging and decoration industry. It is an important equipment for post press packaging processing. The working principle of the die cutting machine is to use a steel knife, a steel wire (or a template carved from a steel plate), and apply a certain pressure through the embossing plate to roll the printed product or cardboard into a certain shape. If the whole printed product is pressed into a single graphic product, it is called die cutting; if a steel wire is used to press marks on the printed product or leave a bent groove mark, it is called an indentation; if two yin and yang templates are used, the printed product is The pattern with three dimensional effect printed on the surface is called embossing, and the above can be collectively referred to as die cutting technology.

Types of die cutting machines

Die cutting machines are mainly divided into three types: Rotary Die Cutting Machine, Rotary Flatbed Die Cutting Machine, and Flatbed Die Cutting Machine according to the different stamping forms. According to the form of template placement, it can be divided into vertical and horizontal. Manual (semi automatic) automatic two kinds according to the degree of automation. In terms of function, in addition to die cutting, there is also a hot stamping function, which is called a hot stamping die cutting machine, and some have an automatic stripping function, which is called a stripping die cutting machine.

Rotary die cutting machine

It is characterized by line contact, low die cutting pressure and high production efficiency. It can be connected with offset printing machines, flexo printing machines, gravure printing machines and other printing equipment for in line die cutting, so it has a wide range of applications. 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 drum 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. It is 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, using the form of pressure cutting or shearing.

Rotary Flatbed die cutting machine

At present, there are few applications in the market, and there is no professional manufacturer in China, so it will not be described here. The flat die cutting machine is the most widely used and the most common type at present, and it is also the model with the most domestic and foreign manufacturers.

Flatbed Die Cutting Machines

It can be used for various types of die cutting, not only semi automatic die cutting with manual feeding, but also fully automatic and high speed linkage die cutting; it can not only die cut corrugated cardboard, cardboard, self adhesive, but also die cut rubber, sponge, sheet metal, etc.

Manual Die Punching Machine

In China, it is commonly known as the tiger’s mouth. It is said that it is similar to the bite action of the mouth when it is working, and it is said that it is unsafe and easy to hurt people, hence the name. Anyway, figuratively illustrates the manual die punching machine work characteristics. The manual die punching 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 its action: single pendulum and double pendulum. The so called single pendulum type means that when die cutting, the press frame swings, the body does not move (that is, the plate table does not move), the plate plate and the press frame are in contact with the lower part first, and the upper part is in contact with the upper part. , In this way, the force time is different, and the force is uneven, so it is used less and less, and it is gradually eliminated. Double pendulum means that when die cutting, both the body and the press frame move. Before contact, the press frame and the platen 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 currently produced belong to this type. According to the degree of automation, manual die punching machine can be divided into two types: semi automatic and fully automatic. At present, the manual die punching machines produced in China are mainly semi automatic, the die cutting is done by the machine, and the paper feeding and delivery are done manually. Since the production quality and production efficiency are related to the operator’s proficiency, it is easy for Wen Gong to use this equipment. Due to the limitation of national conditions, the use of this kind of equipment is common in China, and there are many manufacturers producing large quantities of them. Several factories in Wenzhou that produce manual die punching machines sell more than 100 units per year. But I believe that with the continuous improvement of our national humanistic concept and labor regulations, this kind of semi automatic die cutting opportunity will gradually be eliminated. Correspondingly, fully automatic manual die punching machines have been developed at home and abroad, from paper feeding, die cutting or bronzing, to paper delivery. The typical domestic equipment is the TYM750 hot stamping die cutting machine developed by Beiren Group in 2003. This machine is a post printing equipment with advanced level at home and abroad. It has two functions of die cutting and hot stamping. The whole process of die cutting and hot stamping is completed automatically from paper feeding, die cutting or hot stamping, to paper delivery. High degree of automation, widely used in hot stamping, embossing and die cutting of paper and cardboard, and can also be used in die cutting and hot stamping of some other printing materials. Because of its advanced technology, high degree of automation, and correspondingly high product prices, it is difficult to promote this product in China at present, and it is mainly sold to European and American countries.

Horizontal Flatbed Die Cutting Machine

There are two ways of feeding paper: flat sheet and roll paper, besides die cutting, stripping and bronzing are also available. The horizontal flat die cutting machine with web feeding method is mainly used for die cutting of printed matter such as self adhesive labels and trademarks. Sheetfed horizontal die cutting machines are the most widely used and the most technologically advanced models. There are many manufacturers, foreign well known manufacturers such as BOBST, HEIDELBERG, etc., domestic such as BEIREN, Shanghai YAWA, Masterwork, Tangshan YUYIN, Shangdong Lukes, etc., the market competition is relatively fierce. The main features are high die cutting pressure and wide die cutting range, from 0.1mm whiteboard to <5mm corrugated paper.
