Xincheng Group Xincheng Company 2100 flexo press successfully developed

Many Chinese corrugated cartons and packaging and printing users are increasingly clamoring for the demand for wide-format flexo printers. Some domestic manufacturers specializing in the production of flexo printers have put their eyes and energy into the research and production of wide-format flexographic printers. Henan Xinji Group Xincheng Printing & Packaging Machinery Co., Ltd. held high the leading banner of science and technology, took the lead in development, took the lead in the development of successful 2100 wide flexographic printing presses, and recently held live demonstrations and technical exchange meetings.

Ren Chengping, general manager of Xincheng, is an expert in R&D, production and testing of various types of printing presses for many years. He has extensive research on offset printing presses, gravure printing presses, and flexographic printing presses. In particular, he has paid attention to the technology of flexo printing machines in recent years. Research and analysis of type, satellite type, cascaded narrow-width and wide-format flexographic printing presses, in particular, repeated investigations and careful analysis of first-rate flexographic presses abroad, and extensive exchanges with industry experts, concerning wide-format flexographic printing presses Mature understanding and understanding. When designing a wide-format flexographic printing press, the company integrated the various directors' positions and integrated the overall rack structure and local structure of the world's advanced gravure printing press, full-tension automatic control, and computer overprinting control into a unique design. The concept was completed at the same time in half a year. The design and production were completed and a crew-type 8-color flexo printing machine was successfully built. The whole machine has the comprehensive advantages of reasonable structure, high degree of automation, wide range of performance index parameters, convenient operation and maintenance, high practicability and high cost performance ratio.

This equipment is mainly used for the printing of roll paper and plastic film. Due to the use of flexible resin plates, it has certain tolerance for the surface smoothness and thickness uniformity of paper and plastic film. When using high-grade paper, the printing effect is similar to that of gravure printing presses and offset printing presses. Compared to gravure printing presses and offset printing presses, the printing effect is closer to that of gravure printing presses when using medium and low-grade papers, and the printing efficiency is close to that of gravure printing machines when they are used. Many prints are better than gravure and offset presses.

Equipment has obvious features: automatic tension control makes the printing part of the paper tension stability, to ensure the printing quality; unwinding the use of Mitsubishi automatic tension control system, tension control is stable and reliable; rewinding using independent vector inverter motor drive, synchronized with the main motor PLC Closed-loop control; tension detection with low-friction cylinders, floating pendulum rollers, rotary encoders, and compensation of paper path changes to maintain the stability of the tension; automatic clutch pressure (oil pressure) system, in the clutch pressure, pressure plate roller The pressure of the embossing roller is not separated from the teeth, so that the printing pressure remains unchanged and the printing (overprinting) position remains unchanged when the pressure is applied. When the pressure is applied, the plate roller and the anilox roller are separated and the pressure is separated from the teeth to ensure the anilox roller. Independent rotation makes the ink not block the mesh, and at the same time ensure that the ink transfer pressure is constant when the pressure is combined; the printing wall plate and traction wall plate are high-quality cast iron, and the thickness is 90mm; the base of the host is a high-quality cast iron with a thickness of 160mm, which ensures high-speed operation of the whole machine. Stability, shock absorption, paired machining center machining holes and other installed positions to ensure the position accuracy of the rack wall panel; vertical and horizontal computer overprint system Guaranteed overprinting requirements in the printing process in a variety of random variation factors; the motor drive system of the printing plate roller and anilox roller slide ensures short adjustment time of multi-colored units and improves work efficiency; automatic rewinding of rewinding, Automatic counting guarantees accurate print quantity and saves roll change materials; heat exchange central heat supply and sub unit fan supply air and temperature setting can better adapt to different requirements of air volume, air pressure and temperature adjustment; sealed in and out oven structure The use of heat and secondary circulation ensures thermal efficiency and workshop environment; the complete multi-motor PLC synchronous control system facilitates the addition of other functions of the equipment, online and resource sharing.

At the demonstration site, the equipment was started and the operation was very smooth. The speed could be opened to more than 100 m/min. The noise of the machine was small, and people felt that they were moving quietly. The printing effect is ideal, overprinting is accurate, and the colors are vivid. Although it is a very rare ink-jet flexographic printing, the screen has a layered, three-dimensional effect and a sense of ink. The visiting industry experts and business representatives carefully discussed and carefully discussed and continued to praise. General Manager Ren Jiping said that the design of wide-width machines and narrow-width machines is different. The design must be reasonable and processing is very important. We have chosen the best tension and overprinting control system, and have strict requirements on the design of gears and gears; in order to find the ideal roller, we go through the professional manufacturers in East China to ensure the accuracy and strictly control the vibration within 2 wires; Thick wallboards up to 90mm ensure that the machine runs smoothly.

During the seminar on technical exchanges, everyone gave full affirmation to the equipment and congratulated Xincheng Company for taking the lead in R&D and production of wide-format flexo printers and made significant contributions to the printing industry. The manager of a large carton box company said that there is an urgent need for wide-format flexo printing machines in our paper packaging industry. Flexo preprinting has obvious advantages over gravure preprinting, which is conducive to environmental protection and pollution-free. We have taken a turn around the country and have inspected some manufacturers of flexo presses, but the wide-range machines we see are basically the enlargement of narrow-width machines, and there is no real mature wide-format machine technology. With the trend of preprinting from the gravure printing to flexo printing in the carton industry, the wide range machine of Xincheng Company seizes the opportunity and is very promising. An old Shanghai expert said that the machine is successful and can fully meet the requirements of users. The machine has been ordered by a Taiwanese company in Shanghai and will be shipped soon. With the needs of users, the hot-selling of wide-format flexo printers is imperative in the market.
