How to Treat the Production Speed ​​of Corrugated Cardboard Production Line

In the past two years, the development of the corrugated machinery manufacturing industry in mainland China can be described as rapid progress. On the one hand, emerging manufacturing companies emerge in an endless stream. On the other hand, almost all Taiwanese counterparts set up factories on the mainland, and some well-known foreign brands have come to invest in China. Development, looking at the development trend of the ascendant Wazhao machinery industry, can be said to be mixed with the inherent corrugated machinery manufacturing companies in mainland China. The joy is that in the course of competition, many companies have the opportunity to continuously infiltrate and absorb advanced technologies at home and abroad, which greatly reduces the technological gap between the two camps. The worry is that the direct purchase and production of overseas companies in the mainland is very large. To the extent that their product prices are not as elusive as they were a few years ago. Obviously, with the further narrowing of the technological gap and price gap, the customer groups of the three camps have become increasingly blurred, and this fierce competitive situation in front of them is inevitable. However, speaking from another perspective, this competition will also promote the technological upgrading of China's entire packaging industry and accelerate the internationalization of China's packaging industry.

The author's company as a manufacturing company of corrugated paperboard lines developed in recent years, in the fierce market competition in recent years continue to digest the world's advanced technology, combined with the actual situation of the Chinese industry to carry out technological innovation, many design concepts through the company's associated Enterprise Nantong Emma Packing Products Co., Ltd. practical application, summed up some experience, the following author mainly on the speed of the tile line with some of the views with everyone.

Regarding the definition of the high, medium and low speeds of tile lines, there is currently no clear positioning. However, in the traditional sense of the industry, production speeds below 120m/min should be regarded as low-speed lines, and the maximum production speed can reach 200m. /min can be regarded as a mid-speed line. Normal production speed can be maintained at 200m/min or more for a long time.

In the past two years, due to the ever-increasing competition in the industry, many carton factories in economically developed regions are faced with the problem of retiring old equipment. However, many companies are often indecisive when selecting equipment. The author believes that the speed at which a tile line can be opened has at least the following factors: 1. The design speed of the tile line; 2. The user's order structure; 3. The user's paper structure. The user's order structure and the quality of the paper directly have a decisive influence on the operating speed of the tile. If orders are small and miscellaneous, frequently changing orders will inevitably affect the speed of tile lines, and the structure of paper is a necessary condition for the speed of high-speed tile lines. From the relationship between these three elements, the production efficiency of carton enterprises can be directly affected. Analysis of production efficiency.

From the author's point of view, the improvement of tile line speed will undoubtedly increase the output and thus increase the production efficiency of tile lines. The increase in yield and efficiency will certainly reduce the consumption of coal, electricity, and other units, as well as other constant costs such as labor and finance. However, the tile line speed is too high, and the variable cost of paperboard production, such as the purchase cost of the base paper, will increase, because the high-speed assembly line often puts forward special requirements on paper quality, such as tensile strength and moisture content. From this point of view, when the speed of the tile line is increased to a certain degree, the speed and paper cost input may be inversely proportional. And the excessively high production speed is also a challenge for the effective control of the quality and scrap rate of the cardboard. Because the tile line must maintain a relatively high operating speed, it must provide a higher steam temperature, and the over-low temperature cardboard will be soft, and In the high-temperature production state, once the speed fluctuations occur, it will inevitably cause the board to bend and squat, and it will be brittle and cracked to cause waste. At the same time, paper breaks occur at high speeds, and the resulting loss can multiply exponentially. From this point of view, the improvement of production efficiency does not fully improve the production efficiency. If you value the speed of the tile lines too much, you may miss them.

To sum up, for the vast majority of domestic users, the primary consideration when purchasing equipment is how to effectively control scrap and reduce labor costs. Therefore, a highly automated medium-speed assembly line is not only cost-effective, but also practical. In terms of efficiency and effectiveness of use, it should be more appropriate for most users.
