Congratulations.

First, folding machine

Folding machine according to their institutional characteristics are mainly divided into knife type, fence type and hybrid type three. Twenty years ago, China's printing factories used knife folding machines. Folding machine manufacturers also mainly produced knife folding machines. The structure of the folding machine is more complicated and the folding accuracy is higher. However, due to the reciprocating movement of the folding knife, the folding speed is slow and maintenance is difficult. After 20 years of development, domestic folding machines have now reached or approached the international advanced level. Knife folding machines have gradually withdrawn, replaced by fence-type folding machines and hybrid folding machines, especially hybrid folding machines represent the development direction of folding machines. Taking the YS780 fence folding machine manufactured by Hunan No.2 People's Machinery Factory as an example, it is an international electromechanical integration product in the early 1990s. It adopts a modular structure and has automatic tracking, pneumatic program control to separate paper systems, and frequency conversion. Speed-adjustable, folding speeds up to 180 m/min, steel-rubber combined straight-grain rollers, quick and easy gap adjustment, and high folding accuracy. Another example is that the YH660D type hybrid folding machine produced by this factory is a high-speed folding machine controlled by a human-computer interface microcomputer. It adopts a TD200 text display from Siemens, with pulse frequency and automatic control, variable frequency stepless speed regulation, and stable paper feeding. The company's JZH model can also achieve full positive folding. Domestic advanced folding machines generally adopt PLC control and variable frequency speed control, and some also use touch screen as control panel (such as Shanghai North Manpower's ZYHT660C electronic control force hybrid folding machine), and some use photoelectric integration. Electric knife control device (such as ZYHD490 electric knife hybrid folding machine of Shanghai Zihong Company).

Internationally advanced folding machines are widely used in computerized control to meet the needs of digital printing. They are developing in the direction of digitization, networking and high automation. Germany's Starr folding machine is a recognized brand name. All of them are modularized and driven by frequency converters. The KD and TD series of folding machines use DCT200O software, and use the latest drive technology and the latest sensor technology of the inverter. Realized automation. Its Ti52 proline folder uses the DCT500 digital control system, which greatly shortens the adjustment time. All function keys for control are displayed on the easy-to-use central control panel. In particular, Stahl Folding Machine has many accessories for users to buy, such as punching, gluing, pressing and binding, printing address and labeling devices, greatly improving the folding quality and folding speed, reducing the number of Time reduced the labor intensity of operators and better adapted to the needs of the short-run market. The Topline Barrier Folding Machine pre-press settings and post-press processing programs can be transmitted via CIP3 files, and various foldings can be directly controlled through predefined program control. Similarly, MBO's Narigator folder can be controlled via CIP3 data transfer. However, there are still some gaps in the function expansion, stability and reliability of home-made folding machines.

Second, the package machine

In the past, the most commonly used domestic package machines were the BBZ-2 linear automatic package machine (maximum production rate of 3,000 units per hour) and the YBF-103 disk package machine (maximum speed of 5,000 machines per hour). The former is not high in molding quality, and the working stability and reliability of the machine are not high. After many years of development, the variety and quantity of the rubber bookbinding machine have grown rapidly, and the degree of automation and the quality of the package have also been significantly improved. There are disc-type, linear-type and elliptical-type machines. The mechanical speed is generally 900. ~1800 hours/hour. Most of the packaged machines adopt PLC control, variable frequency stepless speed regulation, PED temperature control and photoelectric switch, which are high-tech products integrating light, machine and electronics. The processing process is generally manual for the book block, automatic milling back, open groove, gluing (including back glue, side glue), on the cover, real. Shanghai Bose Company's BBY4O/5B disc packer is one of the best. Besides the aforementioned features, it also has a touch screen man-machine interface, a variety of interface languages, including Chinese and English, with fault display and Prompt function, independent upper glue length control device, fully enclosed cover, in line with European CE safety certification. The company's JBBQ40/4 pneumatic elliptical adhesive pack machine is the latest technology product of electromechanical integration. All parts of the machine are matched with imported parts. The pneumatic parts are Festo originals. The machine is also equipped with a paper scrap storage device. One of the ideal equipment for bookbinding.

Third, the paper cutter

Paper cutters are divided into mechanical paper cutters, hydraulic paper cutters, and program-controlled paper cutters. In the past, our country mainly used mechanical paper cutters (also known as ordinary paper cutters) to produce the paper. This type of paper presses and paper cutting machines are mechanically driven, with simple structure, convenient maintenance, and low technological content. The hydraulic paper cutter is hydraulically driven during the paper press. The pressure is large and constant, and the hydraulic components are more demanding and the application is gradually increasing. Program-controlled paper cutters were mainly imported machines twenty years ago. They were mainly tape or drum electronic program control cutters. Today, paper cutters have become one of the highest technology and automation products in post-press processing products. The domestic paper cutter has formed a series of products with complete specifications. There are ordinary paper cutting machine series, hydraulic paper cutting machine series, digital cutting paper cutting machine series and program-controlled paper cutting machine series, which can meet various levels of the national economy, especially the printing industry. Packaging industry and other cutting needs.

QZK program-controlled paper cutter is a technology-intensive intelligent paper cutter that adopts a modular design and integrates computer program control, machine, light, electricity, liquid and air. It is manufactured by several major paper cutting machine manufacturers in China. And each has its own characteristics. However, its appearance, function, safety, reliability and stability have reached the level of the mid-1990s. The new SQZK paper cutter control system produced by Shanghai Shenweida Co., Ltd. adopts a 10.4-inch color display and a floppy disk drive for cutting data transmission or software upgrade. It has a huge storage capacity and can be used for human-machine dialogue. It uses ball screws and linear guide rails. The paper feeder has a high speed of movement and accurate positioning, especially in the safe operation of the paper cutter, implements the European safety CE standard and further takes multiple measures. For example, cutting monitoring devices, two sets of PLC programmable logic controllers, built-in electronic locks, non-contact sensor switches, platen brakes, etc. for high-voltage power supply. You can also purchase optoelectronic protective devices and electrical components that comply with CE standards. Thanks to the European CE certification, the Feida brand paper cutter has successfully entered the European and American markets. The newly-developed QZK22OO program-controlled paper cutting machine is one of the largest size paper cutters at home and abroad. It can meet the needs of mechanized production and large-size packaging and cutting of small paper mills. Only a handful of manufacturers in the world can produce it.

The paper cutter of Zhongjiang Litong Company adopts a number of patented utility model technologies to achieve a very high level of the entire machine. For example, the overall use of a double-rail integrated grooveless table technology has changed the middle slot of the table and the middle guide of the paper feeder. The movement method is that the entire workbench has no groove, and the paper feeder uses guide rail guides on both sides of the workbench, which improves the rigidity of the workbench, and greatly improves the impact resistance and stability of the paper pusher.

Foreign paper cutters are mainly hydraulic and program-controlled, especially program-controlled paper cutters have reached a fairly high level, and they are commonly used in ergonomics for modular design. Their features are automatic display of cutting size and cutting error compensation. There has been great development in security protection. In addition, the paper cutter has good stability and reliability. The Polared type paper cutter is recognized as the most advanced paper cutting machine and has a high-accuracy measurement and positioning system. The position accuracy of the cutting position can reach 0.01mm, and a high-resolution color display is displayed, with 29 kinds of texts. Operation information; If the cutting material changes or deforms, the corresponding correction function can be used to correct the paper size error; the self-diagnosis system enables the operator to eliminate the fault as soon as possible. The machine also provides the user with a variety of additional features including stripping. The ED cutter is equipped with a variety of safety devices that make the machine extremely safe and comply with European and German safety certifications. The Porsche Machine Company is the founder of CIP3. It developed the Compucut software system. If the pre-printed layout data is transferred to the computer system, the cutter can automatically optimize the paper cutting program, thus shortening the auxiliary time. .

At present, the main gap between domestic paper cutters and foreign brands is in the aspects of cutter performance, stability, reliability, frequency of failure, supporting capabilities, and providing users with various cutting system configurations. In addition, the supporting domestic electrical components, computers, hydraulic components, pneumatic components can not fully meet the requirements of the cutter, the export machine must rely on imported components. Nowadays, foreign brand-name paper cutters are moving toward the overall cutting system instead of stand-alone cutting, that is, toward the combination of paper cutters and auxiliary systems into a network system. China is a big producer of guillotine papers. The variety is complete and the manufacturing level has reached a very high level. Joining the WTO has provided an excellent opportunity for domestic paper cutters to enter the foreign developed markets. To this end, we must pay attention to the product's innovative design, brand effect, intrinsic and appearance quality, but also pay attention to the development of the cutting system. At present, in addition to Shenweida's production of some paper cutter auxiliary machines, other manufacturers also only produce paper cutting machine mainframes, and they cannot yet form cutting production lines.
