Level analysis of automatic flat die cutting machine
Automatic flat die-cutting machine is the key equipment for printing and packaging post press processing. It is not only an efficient, safe and high-quality molding equipment, but also an updated product of flat die-cutting indentation machine (tiger mouth die-cutting machine), which is favored by packaging and printing enterprises. The wide application and broad market prospect of this kind of equipment have attracted many enterprises to enter the manufacturing ranks of automatic flat die-cutting machines. As a result, China's automatic flat die-cutting machines have formed a complete product series and reached a higher level in technology.
The working principle of the automatic flat die-cutting machine is that the paper is fed into the front gauge and side gauge for positioning by the paper feeding part of the paper feeder, and then the paper is sent to the die-cutting mechanism by the tooth row for secondary positioning for die-cutting. After the die-cutting, the tooth row is sent to the waste cleaning mechanism, and the waste is removed before entering the paper receiving department, so as to complete the die-cutting operation. China's automatic flat die-cutting machine technology has been greatly improved, mainly in: advanced enterprise equipment die-cutting speed index has reached N8000 sheets / hour, die-cutting accuracy has reached ± 0.1 ~ 0.2mm, most enterprises produce automatic flat die-cutting machine generally with waste cleaning device, and some enterprises can manufacture holographic gilding die-cutting dual-purpose die-cutting machine, also Some enterprises can manufacture die-cutting corrugated paper automatic flat die-cutting machine and semi-automatic flat die-cutting machine. The basic parts of these equipments are mostly steel structure wallboard, which are processed by machining center. The precision and rigidity are fully guaranteed. The technical difficulties of automatic flat die-cutting machine, such as cam intermittent mechanism, chain guide rail, paper teeth row, have our own patent technology and intellectual property rights. Touch screen technology, frequency control technology and programmable controller technology are widely used in the equipment, which greatly improves the stability and reliability of the equipment. The fact that the export of molding equipment has increased year by year and the import has decreased sharply in 2004 has proved that the technical level of domestic automatic flat die-cutting machine is improving and the recognition of users is increasing.

In order to ensure the product quality of this type of die-cutting machine, the National Printing Machinery Standardization Technical Committee has formulated relevant technical standards at the end of last century, including JB / t8161998 flat pressing die-cutting machine and JB / t9151999 flat pressing stamping machine, which are used to guide enterprise production and national quality supervision and random inspection.

Development direction of automation, intelligence and multi-function
Data communication among multiple programmable controllers of die-cutting machine; LCD intelligent operation display screen, man-machine dialogue; using optical fiber sensor to detect cursor, accurate positioning; digital servo; holographic aluminum foil surface tension control; hot stamping holographic mechanical precision manufacturing technology will continue to use. In addition to die-cutting, but also required to be able to stamping and automatic cleaning. Take the CNC die-cutting machine of Kunlun Machinery Company as an example, from paper feeding, die-cutting / stamping, to upper and lower lamination / waste discharge, and finally paper receiving / sheet cutting are all completed automatically. Users do not require absolute high speed, but stable and reliable. Die cutting machine as the main equipment of post press packaging printing processing, has formed different grades in China, for a variety of printing and packaging products, complete categories, rich variety of equipment family, basically meet the domestic demand for equipment.
The development trend of die cutting machine has the following characteristics:
1. Die cutting with rotary line will be the best way for mass printing and packaging products. It has been used in flexographic printing production line, form printing machine, corrugated printing slotting die-cutting machine, rotary self-adhesive trademark printing machine, gravure printing die-cutting production line, etc. With the development of printing technology, especially the improvement of processing technology level of circular die cutting cylinder, the application scope of circular die cutting will be more extensive, and the production efficiency of die cutting will be further improved.
2. With the rapid development of printing and packaging industry, the scale of enterprises is expanding. The application market of automatic flat die cutting machine will continue to expand. In contrast, the semi-automatic flat die-cutting indentation machine sales market will further decline, in addition to low productivity, operator labor intensity and other reasons, poor safety, prone to industrial accidents, is the main reason for its decline. However, due to the large scale gap of China's printing and packaging industry, this kind of equipment will still have a certain market and will still play a role.
3. Traditional label printing press manufacturing enterprises. Production has entered a difficult period, and the production and sales volume has been decreasing year by year. The main reason is that the production and sales of high-tech products - high-efficiency rotary satellite trademark printing press and flexographic printing press have increased, and the production efficiency of printing and continuous rotary die-cutting is far higher than that of the backward production equipment of intermittent printing and intermittent flat die-cutting.
4. China has imported many large format sheet fed printers with full sheet. The maximum paper feed size of libida 1620, represented by gaobao, etc., is 1200mmx1620mm, and the printing speed is 120d0 sheets / hour. With glazing and far-infrared drying devices, the ultra full sheet fed printers with maximum paper feed size of 1300mmx1850mm and 1020mmx2050mm have been developed. There are also three printing machinery enterprises in China that have started to produce full sheet fed printing machines with the maximum paper feed sizes of 1020mmx1420mm and 1020mmx1440mm respectively, and the maximum printing speed of 5000-7000 sheets / hour. With the introduction of full sheet paper and the expansion of the market, there will be a demand for die-cutting processing equipment for packaging and printing products. The CNC die-cutting machine adapted to full sheet size has been mass produced in our country. Taking the die-cutting machine produced by Kunlun Machinery as an example, the die-cutting speed of the machine reaches 12000 sheets / hour, ranking the world's advanced level.
Die cutting machine is mainly used for high-grade color box, color box, paper trademark die-cutting indentation, is the ideal equipment in packaging and decoration industry. Yutian Shengtian printing and Packaging Machinery Co., Ltd. has formed four series of various products of die-cutting machine - MS series intelligent paper feeding automatic die-cutting indentation machine, ms-p series intelligent paper feeding automatic die-cutting indentation machine, MX series suction paper feeding automatic die-cutting indentation machine, mx-p series suction paper feeding automatic die-cutting indentation machine.
