New Machine Group Xincheng 2100 Flexo Printing Machine was successfully developed

Many domestic corrugated boxes and packaging and printing users are increasingly demanding wide-format flexo printing machines. Some domestic manufacturers of flexographic printing machines have turned their attention and energy into the development and production of wide-format flexo printing machines. Henan Xinji Group Xincheng Printing and Packaging Machinery Co., Ltd. holds the leading banner of technology and is the first to develop a successful 2100 wide-format flexographic printing press. It has recently held live demonstrations and technical exchanges.

Ren Jiping, general manager of Xincheng Company, is an expert in the research, development, production and testing of various printing machines for many years. He has deep research on offset printing machines, gravure printing machines and flexo printing machines, especially in recent years, focusing on flexo printing machine technology. Research, analysis of satellite, cascading, narrow-width and wide-format flexo presses, especially for the repeated inspection and careful analysis of foreign first-class flexo presses, and extensive communication with industry experts, 遂 for wide-format flexo press technology A mature understanding and grasp. In the design of wide-format flexo printing machine, we integrate various directors and integrate the whole frame structure and partial structure of the world advanced gravure printing machine, automatic control of full tension, computer overprint control, etc. to form a unique design. The concept, in half a year, completed the design and production, successfully created a unit-type wide 8-color flexo printing machine. The whole machine has the comprehensive advantages of reasonable structure, high degree of automation, wide range of performance index parameters, convenient operation and maintenance, strong practicability and high performance-price ratio.

This equipment is mainly used for the printing of roll paper and plastic film. Due to the use of flexible resin plate, it has certain tolerance to the surface smoothness and thickness uniformity of paper and plastic film. When using high-grade paper, the printing effect is close to that of gravure printing machines and offset printing machines. When printing medium and low-grade paper, the printing effect is better than that of gravure printing machines and offset printing machines. When using plastic film, the printing effect is close to that of gravure printing machine, and when it is oversized, it is wide. Many printing suitability is superior to gravure presses and offset presses.

The equipment has obvious features: full-automatic tension control makes the paper tension of the printing part stable, guarantees the printing quality; the unwinding adopts the Japanese Mitsubishi automatic tension control system, the tension control is stable and reliable; the winding is driven by the independent vector variable frequency motor, and the main motor synchronous PLC Closed-loop control; tension detection has low-friction cylinder, floating pendulum roller, rotary encoder, at the same time compensates the change of paper path, maintains the stability of tension; automatic clutch pressure (oil pressure) system, when the clutch pressure, the plate roller The pressure is not separated from the embossing roller, so that the printing pressure is constant and the printing (overprinting) position is unchanged during the pressing; when the pressing roller is separated from the anilox roller and the pressure is released from the tooth, the anilox roller is ensured. Independent rotation makes the ink not block the netting, and ensures the ink transfer pressure does not change when the pressure is combined; the printed wallboard and the traction wallboard are high-quality cast iron with a thickness of 90mm, and the main base is made of high-quality cast iron with a thickness of 160mm to ensure high-speed operation of the whole machine. Stability, shock absorption, machining holes in the machining center and Other installed positions to ensure the positional accuracy of the rack wall panel; vertical and horizontal computer overprinting system Ensure the overprinting requirements in the printing process under various random variation factors; the motor drive system of the plate roller and the anilox roller slide ensures the adjustment time of the multi-color unit is short, and the work efficiency is improved; the winding is automatically cut, Automatic counting ensures accurate print quantity and saves roll-changing materials; heat exchange central heating and sub-unit fan supply and temperature setting can better adapt to different requirements of air volume, wind pressure and temperature adjustment; sealed inlet and outlet oven structure And thermal secondary circulation to ensure thermal efficiency and workshop environment; the whole machine multi-motor PLC synchronous control system, easy to increase the other functions of the equipment, online and resource sharing.

At the demonstration site, the equipment was started, the operation was very stable, the speed could be driven to more than 100 m/min, and the machine noise was small, which made people feel quietly moving forward. The printing effect is ideal, the overprinting is accurate, the color is bright, and it is very rare. Although it is ink-jet flexographic printing, the picture has layers, strong stereoscopic effect and ink feeling. The industry experts and business representatives who visited were carefully discussing and carefully discussing and continually praised them. General Manager Ren Jiping said that the design of wide format and narrow range is not the same. The design should be reasonable and the processing is very important. We have selected the best tension and overprint control system, and strict requirements in designing gears and gears. In order to find the ideal roller, we will run professional manufacturers in East China to ensure accuracy and strictly control the vibration within 2 wires; Thick wall panels up to 90mm ensure that the machine runs smoothly.

During the technical exchange seminar, everyone fully affirmed the equipment and congratulated Xincheng on the development and production of a wide-format flexo press, which made a significant contribution to the printing industry. The CEO of a large carton box company said that our paper packaging industry has an urgent need for wide-format flexo printing machines. Flexographic pre-printing has obvious advantages over gravure pre-printing, which is conducive to environmental protection and pollution-free. We have been in the country for a turn and have visited some professional manufacturers of flexo printing machines, but the wide-format machines we saw are basically the enlargement of narrow-width machines, and there is no truly mature wide-format technology. Under the trend of pre-printing from gravure to flexo in our carton industry, Xincheng's wide-format machine seizes the opportunity and is very promising. An old Shanghai expert said that the machine is successful and can fully meet user requirements. The machine has been ordered by a Taiwanese company in Shanghai and will be shipped shortly. With the user's needs, wide-format flexo printing machines are indispensable in the market.
