Focusing on the electronic shaft transmission technology

normal align=left> internationally, as a new generation of products, the electronic shaft transmission gravure printing machine has been expected to replace the traditional mechanical transmission gravure printing machine

cello pack's mi reduced the energy consumption of 100 million tons of standard coal. LLS said, "we purchased PCMC's 50 inch Infiniti electronic axis printing machine, which provides us with leading technology. The sleeve system is also very valuable for us to reduce refueling downtime."

normal> Application of electronic shaft transmission technology

normal> over the years, the printing manufacturing industry is constantly exploring safety, environmental protection, humanization and other aspects, and pursuing personalization, modularization and scientization in product structure. At present, users and manufacturers of printing enterprises all over the world are focusing on the development of electronic shaft transmission technology

electronic shaft transmission is also known as servo transmission, or independent transmission, no mechanical transmission, etc. its development is the product of the combination of mechanical transmission and the wide application of electronic technology

the electronic shaft transmission technology uses a separate servo motor drive to replace the original mechanical long shaft transmission to improve the channel in the island. The internal virtual electronic shaft is formed through the program (software). The data transmission between the electronic shafts is carried out through the high-speed field bus. Each plate roller runs with the virtual electronic shaft to ensure the strict synchronization of the plate roller phase

transmission control companies are basically the first to bring this technology to the market, such as Rexroth and Lenz in Germany, Sumitomo in Japan, and begalay in Austria. At drupa 2004, the application of electronic shaft transmission technology is everywhere

the combination of electronic shaft transmission technology and various printing methods will bring great changes to the printing industry, and it is also the best solution to deal with the growing short edition

in addition to using less or no plate cylinder and its related equipment to fully reduce costs, the electronic axis printing machine can maximize flexibility. The infinite variability of the drum makes flexible packaging processors such as cello pack achieve high-quality printing results by using intaglio printing, so that they are more competitive in the market. <" He Minghui, head of Zhejiang Wansheng plastic packaging Co., Ltd., told reporters that according to Tom Jacques, global business development manager of PCMC, electronic axis printing machines can help processors avoid problems caused by misoperation in processing

Fredman company, a flexible packaging processing enterprise, produced better quality products after introducing emerald825 eight color electronic axis printing machine, which increased its order volume by 30% over the previous year. The company also predicts that the application of electronic axis printing machine in the market will reach a peak within five years

comparison between electronic shaft and mechanical shaft

the electronic shaft (electronic shaft) transmission technology is applied to the gravure printing machine. Each printing unit is independently driven by a High-Performance AC servo motor, and all printing operations are synchronously controlled by the central controller. Because the electronic shaft (electronic shaft) transmission technology is used to replace the mechanical shaft transmission, the gravure printing machine has the advantages of fast initial registration, fast speed, low lifting speed and waste material loss, The unit has the characteristics of flexible use, shortened printing preparation time and simplified mechanical structure

advantages of electronic shaft

compared with ordinary mechanical shaft transmission, the advantages of electronic shaft (electronic shaft) transmission are obvious:

1. High precision and high-speed chromatic function

the motor has millions of pulses per revolution, which can be used for very precise positioning, proportion and speed control. Coupled with intelligent drivers and high-speed microprocessors, the control of registration accuracy can be greatly improved. This kind of ELS system (electronic line shafting) with electronic circuit instead of shaft rod transmission enables the concept of unit drive to be realized

2. Quick pre registration function

the inevitable torque instability and the hysteresis of the gear when using the gear and shaft rod transmission system will cause the registration to drift, especially when accelerating or decelerating. In the process of use, mechanical wear is inevitable, and the error will increase. Gear is also the main source of stripe (or bar) failure in printing

3. Simple mechanical structure and high precision

the rotation of the drum on the printing machine is no longer limited by the gear pitch, and the repetition length of the printed matter is not fixed, but can be adjusted at will

4. High automation of machine control

in addition to eliminating high-power drive motors, the monthly production capacity has reached 6500 tons to reduce power consumption, a series of mechanical transmission mechanisms have been cancelled at the same time

5 Waste and substandard products are reduced, and production efficiency is improved

servo motor and synchronous motor provide highly constant torque during the whole operation process, and have low inertia or hysteresis when changing speed quickly. As a result, especially in the case of more flexible short version, it shows its advantages


aspects that need to be broken

at present, the efforts of the electronic shaft driven gravure press are as follows:

1 Reduce the cost of gravure printing machine driven by electronic shaft

2. Improve the reliability of the system

3. Improve system solutions

4. Assist users to formulate and implement more appropriate training plans and improve the supply of spare parts to ensure continuous production

5. Strive to expand product exports
