Demand and Development of Folders

Folding machines are the necessary equipment for bookbinding. In order to meet the demands of the printing market for short print production cycles, small batches, high quality requirements, and more and more personalized prints, bookbinding customers urgently need high quality, high speed, and high automation level folding machines. The folding machines produced by many companies such as STAHL, MBO, Japan Zhengrong, Hunan No. 2 People’s Machinery Factory, Shanghai Zihong, and North Manshun comply with this demand. The folding machines they produce are almost all hybrid and fences. The folding machine represents the direction of the current folding machine.
Heidelberg's STAHL folding machine is an internationally recognized brand name product. TI52 PRO LINE folding machine adopts DCT500 digital control system, which greatly shortens the adjustment time and improves productivity. The system's built-in counter counts the number of sheets on the sheet and paper stack, records production data, and all function keys for folding machine control are displayed on the easy-to-use central operation panel. The folding machine is driven by a frequency converter and can be infinitely variable in the range of 10-180m/min. It uses a soft polyurethane folding roller, does not slip, good wear resistance, to ensure the highest folding accuracy. When folding thin paper, hard polyurethane folding rollers can also be purchased. Paper separation is regarded as the best separation system - Stahl TREAMAT splitter, speed up to 40,000 rev / h; the paper feeder system can be configured with side blower to meet the needs of high-speed separation. The folding machine is very suitable for small and medium-sized copying and short-page folding of jobs with frequent job changes. Stahl also adopts a modular design of KD, TD series folding machines. The maximum linear speed of the folding roller can reach 230m/min. Using DCT2000 digital control technology, the machine's adjustment and folding process are automated through the intelligent DCT2000 software, the latest drive technology with the inverter and the latest sensing technology, and the use of the possibility of frequent conversion of the web with LPS pre-stacker, continuous feeder feeder system and high-efficiency delivery system to improve the productivity of anti-page machine; CAN D is also used for bus technology with automatic mode, automatic adjustment speed, paper distance, and paper detection To ensure high-speed folding production safety. Various STAHL folding machines generally have many attachments for users to buy, such as glue, punching, zone tight binding, printing address and labeling devices, thereby improving the folding quality and folding speed, reducing the auxiliary time, Better adapted to the processing requirements of today's short-run prints.
At present, domestically-made hybrid folding machines and fence-type folding machines have developed rapidly and have reached a fairly high level. The ZYH660D Hybrid Folding Machine newly developed by Hunan No.2 People's Machine Factory is a high-speed folding machine controlled by a human-machine interface microcomputer. It adopts a Siemens TD200 text display and has a digital display and setting adjustment function of pulse frequency and pulse width, which can be accumulated. Counting and batch counting; feeder system uses light, machine, electricity, gas automatic program control, stable and reliable paper feeding, paper feeding speed using variable frequency stepless speed, paper separation speed up to 30,000 sheets / h; JZH models can be achieved All positive folding. In addition to the double-line type with all the single page folding function, but also with 32 open double folding function; folding roller with steel roller / polyurethane straight line folding roller, high folding accuracy, low noise, long life, oil resistance it is good. The ZYS780 fence type folding machine produced by this factory is an electromechanical integrated product of international water in the early 90s. The folding speed can reach 180m/min, and the modular structure of the building blocks is used to control the frequency.
The ZYHT660C electric-controlled knife blending folding machine produced by Shanghai North Manshun Printing Machinery Co., Ltd. is a combination type machine. This machine is particularly suitable for some special page-removing requirements, and is especially used for folding open-face format into twenty-four open specifications. The core part of the electric control knife adopts the original imported parts of Japan KEB Company. The reaction is sensitive, the speed is quick, and the adjustment and maintenance are convenient. The control circuit adopts the advanced Digital touch screen as the control panel, Panasonic PLC logic controller as the control center, and the circuit has the digital setting paper. Long, paper distance, suction distance, main motor speed function and display function. It has protection instructions such as main frequency converter, double sheets, and folding knife exceptions, and it can stop quickly. The ZYS560A Folding Folding Machine can perform eight parallel foldings, while the ZYH920 Folding Machine can perform 16-page slashing folding.
Shanghai Zihong Company's ZYHD490 electric control knife hybrid folding machine electrical system adopts PLC and frequency conversion speed control. The control knife device and high-performance paper feeder head of the photoelectric table ensure the high speed and reliability of folding.
In recent years, domestic folding machines, especially hybrid folding machines and barrier folding machines, have made great strides in terms of folding speed, folding accuracy, automation, and stability, but with international Compared with the advanced models, there is still a certain gap between the stability and reliability of the machine in the degree of automation and function expansion of domestic folding machines. To meet the market demand, we need to further improve the level of automation of the folding machine, shorten the production of auxiliary time, under the premise of ensuring the quality of folding to further improve the speed of the folding machine, and try to provide a variety of functional configurations. In terms of integrated processing with prepress and printing, some foreign models have gone ahead and are worth learning from. For example, the Stahl Topline fence folding machine in Heidelberg, Germany sets the post-press finishing program before printing. It can directly complete all kinds of folding through CIP3 file transfer. The machine contains 81 sets of preset programs, after inputting the length and width of the paper, The parameters can be set and calculated by itself, and the fence panel and the side guide device can be controlled to complete the predetermined folding. Another example is MBO's Navigator folding machine is an artificial intelligence machine, which can be controlled by CIP3 data transmission, and can achieve remote error diagnosis and error recovery functions. This type of machine emphasizes on-line processing automation. In addition to the need for digital printing, MB Shoei developed a computer-controlled folding machine, emphasizing single-machine automation. Its degree of automation is very high. When a folding style is selected, the machine can be automatically disassembled by simply feeding a folding paper. Out of the book stickers. In short, the development of folding machines to digital, network, and high automation is a general trend. Our folding machine manufacturers must also comply with this trend.
