Discussion on the latest trend of die cutting machine

die cutting machine is mainly used for die cutting, indentation and cold embossing of trademarks, cartons, greeting cards, etc. in the paper packaging and decoration industry. It is an important equipment for post press packaging processing and molding. The working principle of the die-cutting machine is to use a steel knife, steel wire (or a template carved from a steel plate), exert a certain pressure through the imprint plate, and roll the print or cardboard into a certain shape. If the whole print is pressed into a single graphic product, it is called die cutting; If you use steel wire to press out traces or leave bending grooves on the print, it is called indentation; If you use the Yin and Yang templates to imprint a three-dimensional pattern on the surface of the print, it is called convex concave imprinting, which can be collectively referred to as die-cutting technology

types of die-cutting machines

die-cutting machines are mainly divided into three types: round pressing, round pressing and flat pressing according to different stamping forms. According to the form of template placement, it can be divided into vertical and horizontal. According to the degree of automation, there are manual (semi-automatic) and automatic. In terms of function, in addition to die cutting, there is also bronzing function, which is called hot stamping die cutting machine, and some have automatic waste removal function, which is called waste removal die cutting machine

what are the new measures taken by the regulatory authorities of the round market? Focusing on market access, optimizing the business environment, reducing the burden of enterprises and other issues, the characteristics of the rounding die-cutting machine are line contact, low die-cutting pressure and high production efficiency. It can be connected with offset press, flexo press, gravure press and other printing equipment for online die-cutting, so it has a wide range of applications. A roller is equivalent to an embossing roller, which applies pressure during die cutting; The other is the drum knife mold. There are two kinds of drum knife dies: wood and metal. The former mainly cuts thick corrugated cardboard, while the latter has metal drum knife dies processed by chemical corrosion or electronic carving methods, which are mainly used for cutting self-adhesive labels and trademarks. There is also a metal drum knife die, which is mainly used for medium and high-end long-term products, in the form of pressure cutting or shearing

at present, the circular flattening die-cutting machine is rarely used in the market. There is no professional manufacturer in China to continuously improve the production efficiency and product quality of the tire industry, so I won't repeat it here

the flat pressing die-cutting machine is the most widely used type at present, and it is also the model with the most manufacturers at home and abroad. Domestic manufacturers include Shanghai Yahua, Tangshan Yuyin, beiren group, Henan Xinji group, Beijing Shengli Weiye Printing Machinery Co., Ltd; Abroad, there are Swiss Bobst, German img, Japan Asahi, American standard carton machinery company, Spain IBERICA, South Korea youngshin Machinery Co., Ltd. and Japan Iijima, which also bring opportunities for their cooperation and Heidelberg and other manufacturers. The flat press die-cutting machine can be used for various types of die-cutting, which can not only manually continue the paper semi-automatic die-cutting, but also fully automatic high-speed linkage die-cutting; It can die cut corrugated board, cardboard, self-adhesive, and rubber, sponge, metal plate, etc

vertical flat die-cutting machine, commonly known as tiger mouth, is named for its bite action similar to the mouth when working and its unsafe and easy to hurt people. In any case, it vividly illustrates the working characteristics of the vertical flattening die-cutting machine. The vertical flat die-cutting machine is mainly divided into two parts: the body and the press frame. If the die-cutting platform is installed on the body, otherwise it is unqualified. According to its action mode, there are two types: single pendulum and double pendulum. The so-called single pendulum type refers to that during die cutting, the pressing frame swings, the body does not move (that is, the plate table does not move), the plate table contacts with the lower part of the pressing frame first, the upper part then contacts, and the upper part leaves first, and the lower part then leaves at the end of die cutting. In this way, the stress time is different and the stress is uneven, so the use is less and less, and it is gradually eliminated. Double pendulum refers to that during die cutting, both the machine body and the press frame act. 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. At present, most of the vertical flat pressing and die-cutting machines produced belong to this type. According to the degree of automation, the vertical flat die-cutting machine can be divided into two types: semi-automatic and full-automatic. At present, the vertical flat die-cutting machine (tiger mouth) produced in China is mainly semi-automatic. Die cutting is completed by machine, and paper feeding and receiving are completed manually. Because the production quality and efficiency are related to the proficiency of operators and are prone to safety accidents, the United States and other developed countries have expressly banned the use of this equipment. Due to the limitations of national conditions, the use of this kind of equipment is still relatively common in China, and there are many manufacturers. Due to the low price and large production and sales volume, for example, the annual sales volume of several factories producing tiger mouth in Wenzhou is more than 100 sets. However, I believe that with the progress of our national humanistic philosophy and the continuous improvement of labor laws and regulations, this kind of semi-automatic die-cutting opportunity will be gradually eliminated

accordingly, full-automatic vertical flattening die-cutting machines have been developed at home and abroad, which are automatically completed from paper feeding, die cutting or bronzing to paper receiving. The typical domestic equipment is the tym750 hot stamping die-cutting machine developed by beiren group company in 2003. This machine is a post press equipment with advanced level at home and abroad at present. It has two functions of die cutting and bronzing. The whole process of die cutting and hot stamping is completed automatically from paper feeding, die cutting or bronzing to paper receiving. It is simple to operate and has a high degree of automation. It is widely used in hot stamping, embossing and die cutting of paper and paperboard, as well as die cutting and hot stamping of some other printing materials. Due to its advanced technology, high degree of automation and correspondingly high product price, it is difficult to promote this product in China at present, and it is mainly sold to European and American countries

horizontal flat press die-cutting machine has two paper feeding methods: flat paper and web paper. In addition to die-cutting, it can also have waste cleaning and bronzing functions. The horizontal flattening die-cutting machine with web feeding mode is mainly used for die-cutting of self-adhesive labels, trademarks and other printed materials. The flat paper horizontal flat pressing and die cutting machine is the most widely used and fastest-growing model. There are many manufacturers. Foreign well-known manufacturers such as boster and Heidelberg in Switzerland, and domestic manufacturers such as beiren group, Shanghai Yahua, Taiwan Youheng, Tangshan Yuyin, Shengli Weiye, etc., have fierce market competition. The main feature is that the die-cutting pressure is large and the die-cutting range is wide, from white board with value= ".1" hasspace= "false" negative= "false" numbertype= "1" tcsc= "0">0.1mm to corrugated paper with value= "5" hasspace= "false" negative= "false" numbertype= "1" tcsc= "0">5mm

development trend of die cutting equipment

1. Development in the direction of automation, intelligence and multifunction

data communication between multiple programmable controllers of die cutting machine; LCD intelligent operation display screen, man-machine dialogue; The optical fiber sensor is used to detect the cursor and locate it accurately; Digital servo; Holographic aluminum foil surface tension control; Hot stamping holographic machinery and precision manufacturing technology will continue to be used. In addition to die cutting, it is also required to be able to bronze and automatically remove waste. Take the tym750 hot stamping die-cutting machine of beiren group company used in the United States as an example. Each worker can manage four devices at the same time, from paper feeding, die cutting or bronzing to paper receiving. Users do not require absolute high speed, but require stability and reliability

2. The demand for the linkage line of the circular die-cutting machine will further expand.

the circular die-cutting machine can easily form a printing die-cutting production line with offset printing, flexo printing, gravure printing and other printing methods (web feeding). The positioning and registration accuracy of printing, die-cutting and indentation can be improved through the tension control system of web feeding; Production and processing in the form of linkage can improve production efficiency. The die-cutting structure of round pressing is line contact, with low pressure and long service life of the die-cutting roller. In addition, the fastest-growing parts of packaging and printing are film and metal foil, which also brings new opportunities for circular die cutting machines

3. Continuous application of digital information technology

at present, printing technology has entered the digital information era, and digital information technology has also been gradually applied to die-cutting equipment. There are two main explanations for the digitalization of die-cutting machine. One is the digital interface technology, that is, the requirements of JDF technology on the die-cutting machine, which is mainly used for the reception and feedback of data information; Another kind can be explained as stencil free die cutting, that is, the graphic data of the prepress system directly controls the cutting head to die cut the printing sheet, which is suitable for personalized die cutting of short versions
