Technical Status and Development Prospect of Fully Automatic Printing Slotting Die Cutting Machine

With the emergence of automatic printing slotting die-cutting machine, it has been proved that among many kinds of printing equipment, the technology of die-cutting machine products in China has reached a high level. Its main signs are in several aspects:

First, the import of die-cutting machines has declined and the export volume has been increasing.

According to customs statistics, 461 moulded equipment were imported in 2002, 25.291 million U.S. dollars; 455 moulded equipment were imported in 2003, 26.028 million U.S. dollars; 213 moulded equipment were imported in the first three quarters of 2004, 17.151 million U.S. dollars; the import trend is expected to decline throughout the year. In 2002, 765 units were exported, with 10.861 million US dollars; in 2003, 1066 units were exported, with 13.893 million US dollars; in the first three quarters of 2004, 958 units were exported, with 15.591 million US dollars. It is expected that the annual export will exceed that of last year.

Second, the variety of die-cutting machine basically meets the production demand of domestic printing and packaging industry.

In China, trademark die-cutting machines, self-adhesive trademark die-cutting machines, circular die-cutting machines, circular die-cutting machines, circular die-cutting machines, flat die-cutting and indentation machines (slot mouths die-cutting machines) can be manufactured, and in recent years, die-cutting units on linkage lines can be manufactured, such as flexible plate printing machines, gravure printing machines, non-adhesive printing machines, corrugated paper printing.

Thirdly, more than 20 enterprises have manufactured automatic and semi-automatic die-cutting machines.

Horizontal Analysis of Fully Automatic Flat Die Cutting Machine

Fully automatic flat die cutting machine is the key carton equipment for printing and packaging post-press processing. It is not only an efficient, safe and high-quality die-making equipment, but also an efficient, safe and high-quality die-making equipment. At the same time, it is also an updated product of flat die cutting and indentation machine (tiger mouth die cutting machine), which is favored by packaging and printing enterprises. The wide application and broad market prospects of this kind of equipment have attracted many enterprises to enter the manufacturing ranks of fully automatic flat die cutting machine, which has formed a complete series of products and reached a high level in technology.

The working principle of the fully automatic flat die cutter is that the paper feeder feeds the paper into the front and side prescribed positions through the paper feeding parts, and then the paper is sent to the die cutting mechanism by the toothbars for secondary positioning for die cutting. After die cutting, the toothbars are sent to the scrap clearing mechanism, and then the scrap is cleared and then into the paper collecting department to complete the die cutting operation. At present, the technical level of our country's fully automatic flat die cutting machine has been greatly improved, mainly in the following aspects: the die cutting speed index of advanced enterprise equipment has reached N8000 sheets per hour, the die cutting accuracy has reached (+0.1-0.2 mm). Most enterprises produce fully automatic flat die cutting machine with scrap clearing device, and some enterprises can manufacture holographic hot stamping die cutting dual-purpose die. Cutting machine, there are also some enterprises can manufacture die-cutting corrugated paper automatic flat die-cutting machine and semi-automatic flat die-cutting machine. Most of the basic parts of these equipments are made of steel wall panels, which are machined by machining centers. The accuracy and rigidity are fully guaranteed. The technical difficulties of fully automatic flat die cutting machine, such as cam intermittent mechanism, chain guide rail and paper toothplate, all have our own patented technology and intellectual property rights. Touch screen technology, variable frequency speed control technology and programmable logic controller technology are widely used in the equipment, which greatly improves the stability and reliability of the equipment. In recent years, the export of die-making equipment has increased year by year, and the fact that imports dropped sharply in 2004 has proved that the technical level of domestic fully automatic flat die-cutting machine is improving the recognition of users.

 

In order to ensure the quality of this type of die-cutting machine, the National Technical Committee for Standardization of Printing Machinery has formulated relevant technical standards at the end of the last century, including JB/T8161998 die-cutting machine and JB/T9151999 flat-pressing and bronzing machine, which are used to guide the production of enterprises and to supervise and spot check the quality of the country.

In the world, the main manufacturers of fully automatic flat die cutting machine are Swiss Boster, German Stona, Iberga and Yongxin.

In the post-press equipment, the development of automatic flat die-cutting machine is relatively mature. The die-making tools, die-cutting plate-making machine, multi-functional die-making machine and CNC bender, which are matched with die-cutting machine, are all manufactured by manufacturers. This die-cutting mode has formed the mainstream equipment of large and medium batch die-cutting printing and packaging products in China.

Rapid progress in technology of circular die cutting machine

A lot of technical explorations have been made on the circular die cutting machine abroad, and great progress has been made. Fully automatic flat die cutting machine is the main force of modern post-press die-making equipment, which is widely used in folding carton and corrugated carton die-making processing. Because the principle of this die-cutting process is intermittent, the further improvement of production efficiency is limited. Therefore, a circular continuous die-cutting machine has been produced, and the die-cutting speed can be greatly improved. Some data show that Boster has carried out the round die cutting test. The die cutting speed can reach 12 000 sheets per hour and the linear speed can reach more than N300 meters per minute. Some enterprises in our country produce circular die-cutting machine, mainly for corrugated cardboard boxes. The processing accuracy is low, and the die-cutting speed is only 6000 sheets per hour. Round die cutting drum forming method still follows the same splicing die cutting tool method of flat die cutting machine. Although the cost of die making is low, the die life and die cutting accuracy are low, so it is not suitable for connecting line circular die cutting. The circular die-cutting machine for cardboard forming has developed corresponding products, which are mainly used in flexographic press production line, gravure printing production line and dry glue label production.
