Shanghai Liuxiang General Equipment Co., Ltd. alliance of Giga-LX International Group, specializes in the manufacturing and distributing of the Corrugated Cardboard Production Line (Corrugator) and Computerized High Speed Flexo Printer Slotter Die-Cutter (Flexos, or flexographic machine).

With the leading-edge feeder of AC servo controller launching successfully, we have now recently researched and developed an extended pressure-less leading-edge feeder. Based on the principle of AC servo control, we continue the extension function development to solve the problem of flute impression, maintain the original physical index of the corrugated box, and operate efficiently while saving time adjusting. We have shown this new product concept at the SinoCorrugated 2009 which is held in Shanghai New International Expo Center, and received very positive feedback from our customers.

This is an industrial revolution for carton printing machines, which went from chain feeding to automatically feeding via the transmitting rollers, an industry first. Not only does this reduce the labor load intensity, but it also improves the speed of paper feeding.

However, we have discovered a new problem. The transfer through the paper guide roll causes the physical index of the corrugated board to decline due to the amount of pressure on the board. The general level of compressive strength loss is roughly 20%, resulting in a decline in compressive strength as well as bearing capacity, leading to the thinning of the corrugated cardboard and causing the surface liner to appear convex corrugated. Not only is the compressive strength of the corrugated box compromised, but it also seriously affects the carton printing quality.

Manufacturers initially tried to improve the paper guide roller to solve this dilemma. At first, they slotted the paper guide roller to reduce the pressure area on the cardboard but failed; then, they adopted double-layer rubber wrapped rolls, whose soft inside and hard outside can reduce the extent of damage to the cardboard. However, it’s useless in the humid southern regions.

In addition, it’s easy to for the paper guide roller to collide when transporting wrapped cardboard, causing the cardboard to group together and wrinkle. This produces waste, affects the production speed, and occasionally damages the rubber rollers and other components, thus increasing costs and the frequency of maintenance.

A lot of CEOs of carton enterprises often complain that the automatic printing press is not even as good as the chain press, especially when the board thickness changes and becomes a high-energy consuming, inefficient machine.

For example, Mr. Chang’s enterprise in Zhejiang purchased three automatic feeder packaging printers, and later bought seven units of chain-feed presses at one time. However, leaders are still looking forward to top quality, efficient presses every day. Previously, when the carton enterprise communicates with their carton printing machine supplier, they were focused on how to reduce the paper guide roller damage to the cardboard, and thus had no choice but to resolve this international problem.

We will continue to improve as long as we can still find problems. Our company has enhanced and emphasized developing aims to market needs, and we have adopted the established technique of an AC servo-controlled leading-edge feeder, to further extensive research and successfully solve the difficult problem of destroying the cardboard during the transmission by the rubber roller. First of all, by making use of the precisely positioned function of an AC servo controller, we’ve added the upgraded paper-feeding system, which completely avoids damage from the paper-transmitting rubber roller and guarantees 100% physical index accuracy. It facilitates the production of corrugated cardboard cartons to have a wider number of options for the paper. Thanks to cancel the paper-transmitting rubber roller, it avoids the damage to the paper while transmitting and achieve the accuracy of the overprinting, which other leading edge feeder can not compete. As there is no need to adjust the pressure of the rubber roller, the adjusting time is negligible and operates with ease. Furthermore, it could completely ensure the production speed is maintained, especially playing a vital role in the wrapped smooth cardboard production as well as with regard to the stability of the fixed frame on the servo control leading-edge feeder, ensuring the color is correct as well as accurate.

By making use of the pressure release feature of the leading-edge feeder controlled by the servo motor, there will be no pressure on the cardboard, and no signs of corrugation on the paper, thus improving the quality of the printing cartons. Even with the same quality level of paper, the effect is a printing quality that exceeds others of the same product.

In addition, enlarging the dust suction angle is makes it easier to clear the dust on the cardboard, which can help decrease the amount of time needed to clean the printing plate. In these respects, you can improve your manufacturing ability by 20%, which makes significant strides in efficiency and high-quality printing.

With this way can resolve “international” problems, and at the same time, not only improve the turnover, but also decrease maintenance costs, saving on waste and achieving maximum optimization.

We can at the very least assist you in saving 1% of your paper, improve product efficiency by 10%, lessen maintenance expenses, and improve printing quality.

Talk must have action, action must have the results. Although we have no glorious reputation, we fulfill our promises and are able to bring about honest, concrete benefits for you. AC servo control leading-edge feeders have been applied successfully, resulting in more efficient and stable production. And the machines equipped with pressure release have succeeded in commissioning extended feeders, which will allow a manufacturer of corrugated cartons to discover a new vision. Now we warmly welcome your comments on our machine and respectfully await the opportunity to exchange guidance.
