Postpress Equipment Development (I)

After the printing equipment has been well developed in recent years, especially in the concept of system solutions proposed in recent years, many printing machine manufacturers in the printing press manufacturing and sales, have put forward system solutions, to prepress , Post-press development, to related, similar expansion, the formation of a variety of suppliers to provide solutions. The development of CTP technology has led to the traditional classification of printing machinery and equipment according to the traditional classification of pre-press, printing, and post-press equipment to one-machine and system solutions, and the emergence of batch-printing platesetters, digital proofing machines, digital printing machines and combinations. Mechanical equipment, CTP technology is also possible after the development of India. Now companies have begun to expand the process of post-press equipment, such as Beiren Group Corporation, Yingkou Guanhua, Weihai Printing Machinery, Weifang Huaguang, and diversified electric and other companies have all launched a series of post-press equipment.
Such as: high-speed automatic match stapler, die-cutting machine, folding machine, folding machine and match, order, folding automation processing system, and other companies, such as Jingdezhen Printing Machine Company and Weihai Printing Machine Company and India Tangshan Yuyin Company and Changchun Printing Machine Company jointly established “Lianqiang Company” to realize the integration of exhibition, sales and export. The original enterprises such as Shanghai Electric Group Printing and Packaging Machinery Co., Ltd. itself is a company including prepress and printing. The large-scale printing enterprise group after printing has formed a sales model for systematic solutions at home and abroad, and achieved bulk export of paper cutting machines, die-cutting machines and binding equipment. In 2001, exports accounted for 42.4% of the country's total number of printers. It is the largest export-oriented enterprise. With the continuous deepening and development of the market economy, it should be said that the localization rate and market share of postpress equipment are much higher than those before printing and printing. Domestically, it has been able to manufacture the press and publishing industry's printed stacker and keel; the book publishing industry has printed folding machines, paper cutters, three-side cutters, package machines, and sewing machines. , horseback riding stapler, collating machine, rubber binding linkage line, etc.; packaging and printing industry, post-printing die-cutting machine, creasing machine, laminating machine, laminating machine, slitting machine, box making machine, etc. Good market prospects. According to incomplete statistics of 44 companies in 2001, sales totaled 3.171 billion yuan, and total profit was 258 million yuan. Sales volume increased by 18.1% year-on-year, and total profit increased by 9.4% year-on-year. The sales of the five major post-press equipment of the 44 companies completed 677 million yuan, accounting for 21% of the 44 total sales. The following describes the production, sales and technical level of the five major equipment as follows.
There are about 14 manufacturers of folding machines manufactured by folding machines. The main manufacturers are Shanghai North Manshun, Hunan Erin, Zhejiang Jialu, Shanghai Zihong, and Weihai Printing Machines. In 2001, five major folding machine manufacturers produced 661 folding machines, with a production and sales rate of about 94%. Annual sales of nearly 100 million yuan. The main varieties are 780mm, 660mm, 560mm, 490mm, and 420mm specifications. The folding speeds of some products, such as Shanghai North Manshun, Shanghai Zihong and Hunan Second Printing Machine, have reached 160m/min. Frequency conversion speed control and PLC control are commonly used. Some also use the photoelectric control knife and touch screen technology. The folding machine manufacturer Stahl in foreign countries has produced a folding machine at a speed of up to 180 m/min. The maximum speed of the folding roller has reached 230 m/min. The technical measure adopts a pre-stacking device that can perform web conversion and uses Digital technology for production control, automatic mode, automatic speed adjustment, paper distance, and paper detection. This shows that there is still a gap between the quality and performance of our products and similar foreign products.
There are more than 34 manufacturers of paper cutting machines for paper cutting machines. The main companies are Shanghai Shen Wei Da, Changchun Yinji, Sichuan Zhongjiang, Gansu Pingliang Puye, Shandong Heze Shengjian, Zhejiang Jialu and other paper cutter mills. In 2001, a total of 2,003 paper cutters were sold at the statistics of ten paper cutter mills. The sales volume was 284 million yuan. The main paper cutter specifications were 420mm, 580mm, 650mm, 760mm, 780mm, 920mm, 1150mm, 1250mm, 1300mm, 1370mm. ,1550mm,1660mm and other 12 specifications. Shanghai Shen Wei Da's partial product speed reached 40 beats/minute, and was equipped with a paper creel machine, a unloader, an air-cushioned worktable, and a lift to form an automatic paper-cutting production line. There are nine national patents on the paper cutting machine in Zhongjiang, Sichuan Province. The scroll screw and linear guide rails are used to accurately move the stacker and increase the speed of the cutter. The two companies and the Changchun Printing Machinery Factory have ceased to produce backward mechanical paper cutters after product structure adjustment during the “Ninth Five-Year Plan” period. They will be replaced by hydraulic paper cutters, program-controlled paper cutters and microcomputer-controlled paper cutters. Its cut safety device is also protected by multiple layers of protection, such as the fall prevention device of the paper press, two-hand protection protection button, infrared photoelectric protection and built-in electronic locks and other safety protection devices. These technologies bring the level of home-made paper cutters close to the technical performance of foreign Paula and Warrenberg. To say that the gap is mainly manifested in the stability, reliability, completeness and automation of equipment is relatively low. In addition, the market for mechanical paper cutters is quite large. Manufacturers should upgrade their technological level as soon as possible to meet the growing market demand. (To be continued)
