As early as 151 years ago, the British discovered the corrugated structure and invented corrugated packaging.
The corrugated box industry in today's world is undergoing rapid changes. The corrugated board production line is an assembly line composed of the reel base paper after corrugating, gluing, bonding and shaping, paper separation and pressing, cross-cutting into specification board, and finally stacking and outputting. From structure, speed, specification to control, corrugated cardboard production line has experienced a century-old development process from simple to modern, from low speed to high speed and from mechanization to computer digital control mechatronics.
(1) Early manual corrugated packaging technology
Corrugated paper was recorded in England in 1856. The English brothers Edward Healy (edwadciley) and Edward Allen (edwadellen) pressed the paper into corrugated corrugated shapes as the lining of hats to breathe and absorb sweat. Today's corrugated packaging technology, regardless of material selection, structural form, production method, and performance mechanism, all originate from this. Therefore, this has pioneering significance for the invention and development of corrugated packaging technology.
Fifteen years later, in 1871, American Albert Jones (albertjones) invented single-sided corrugated cardboard to process cardboard boxes for packaging glass lampshades and similar fragile items, and obtained the first packaging in the United States. Patent right for corrugated paper. The successful development and application of this single-face corrugated board material has brought corrugated technology into the field of packaging materials for the first time.
Another major breakthrough in corrugated packaging technology was in 1874. Oliver Long in the United States started to paste a layer of lining paper on the other side of single-sided corrugated paper to make double-sided corrugated cardboard and obtain single-sided corrugated cardboard. Corrugated cardboard patent. Thereby, the strength of the corrugated cardboard is greatly enhanced, and the corrugated cardboard is expanded from a single-function liner material to the production of corrugated packaging containers.
Patented in 1874. The product combines cushioning properties, horizontal elasticity and vertical strength, and is suitable as an outer packaging material for glass bottles, lamps and china. All of this corrugated paper was made from the thin straw paper that was used as a paper packaging material at the time.
Robertthompson began producing double-sided corrugated cardboard in 1875. In 1878, henrydnorris partnered with rober to also produce double-sided corrugated cardboard. Soon after, American robergair also began to produce double-sided corrugated cardboard and developed the first die-cutting and creasing machine, but he had a 10-year patent dispute with thompson and norris, and finally was in an unfavorable situation. The problem was resolved satisfactorily in 1888, when gair admitted that thompson and norris had patent rights and paid royalties to obtain the right to produce corrugated board. In 1881, oliverlong patented the first use of tissue paper to support corrugated structures. In 1882, rhthompson patented a machine for the production of double-sided corrugated board in two stages. Each face paper is coated with a layer of glue, and the double-sided corrugated cardboard is pulled in the extension direction of the clamp on the pulling rope through the gluing machine and the brush roller. Variable speed drives seem to do double duty. In 1889, the United States accepted the first patent application for double-sided corrugated cardboard. In 1890, rhthompson patented an improved single-sided machine using steam to heat corrugating rolls and corrugating tip gluing. Extended contact system for better corrugation formation. (Over 100 years later, he was "rediscovered")
Design engineer cflangston immigrated from Wales, England to Philadelphia in 1888 and opened a machine manufacturing factory there. His first design was the shear slitting machine, from which the langston paper roll machine was born. In 1895, the davidweber company commissioned langston to produce single-sided machines. Made the world's first single-sided corrugating machine with a width of 0.5 meters and a moderate 6 meters per minute. It is worth mentioning that it was the first machine manufacturer to dabble in the design of corrugated machines, perhaps because the patent protection for this product has always been particularly strict. In 1895, the first slotted corrugated box came out. In the same year, hinde and dauch introduced the patented climax bottle corrugated packaging, which was then used to package glass lampshades for shipping. Their pioneering work has played a very important role in introducing the article protection function of corrugated paper into railway transportation.
In 1894, the A-type corrugated cardboard developed by Robert Guya was successful, so that the corrugated cardboard can be used as the outer packaging of corrugated boxes for transportation packaging needs. After the corrugated box made of A-type corrugated cardboard first appeared in the United States, it emerged in the packaging industry and was widely recognized by packaging users, and soon became popular in the United States and other places. In 1895, corrugated box packaging began to gain importance in the rail transportation system in the United States.
(2) Develop corrugated packaging technology produced by a single machine
After the corrugated structure was discovered by the British, it began to be produced by hand, and then manufactured equipment, using machinery to produce cartons, and developed into a corrugated production line from a single machine to a single-sided machine. In 1895, the Sefton Manufacturing Company in Anderson, Indiana, installed a landmark corrugated board production line, a machine designed and built by jeffersontferres. It uses gas flame-heated corrugating rollers and claims to be the first sustainable corrugated board production line, which was patented that year. However, the machine broke down frequently, so it was updated in 1900 to use steam heating, but the cross-cutting still required a male worker with a ruler and a sharp knife to operate. The maximum speed is 10 inches (3 meters) per minute, and the width is about 18 inches (450 mm).
In 1897, the hide & dauch paper company produced its first single-sided cardboard using locally made machines in the sandusky, Ohio area. The core paper is pressed between corrugating rolls and rolled into paper rolls, and then processed together with the face paper through a second process called "gluing device" (that is, applying glue to the corrugated tip), the face paper and the core are processed. The paper is thus bonded into single-sided corrugated cardboard. These single-sided cardboards are then re-rolled into rolls. In the following years, hinde&dauch expanded its product range and started producing double-sided corrugated cardboard and cartons. georgewswiftjr also entered the field of tile wire production in 1901. And sell machines to wdcoil, barkley and walker in Indiana.
In 1902, corrugated packaging cartons were officially approved for use in American rail transportation packaging; in 1903, the United States statutory freight classification organization revised regulations to accept corrugated cartons as transport packaging containers. In this year, the French made double-sided corrugated boxes for the shipment of grains and foodstuffs.
Several more double-sided machines were sold to the Fortewayne Corrugated Company around 1906. swift designed the first rotary cutter for tile wire. In the first decade of the 20th century, the width of the tile line reached 1 meter. In 1907, in the United Kingdom, where the corrugated technology originally originated, the corrugated packaging technology developed by the Americans began to be introduced, and the first corrugated boxes produced in the United Kingdom appeared in the market. Japan started producing corrugated boxes in 1914. In 1918, mdknowlton's corrugated board production line was patented.
(3) Rotary single-sided corrugating unit
In 1920, double corrugated cardboard came out, and the manufacturing technology and use of corrugated packaging products developed very rapidly. The "Prideham Case" in the early 20th century marked the real rise of carton packaging, suggesting the defects and deficiencies of wooden box packaging. During the First World War, wooden boxes accounted for 80% of transport packaging, while corrugated boxes only accounted for 20%. During World War II, corrugated boxes accounted for 80% of transport packaging. The use of wooden boxes has dropped sharply, and corrugated boxes have become the most important shipping packaging containers. The production technology and equipment of corrugated packaging products are developing simultaneously with the application of corrugated boxes. In the early 1920s, the production technology of corrugated products began to replace the early manual operation with stand-alone production.
In 1922, the electric single-sided corrugating machine with a width of 1.32 meters was born.
In 1923, a single-sided corrugating machine with a width of 1.6 meters appeared.
In 1925, a single-sided corrugating machine with a width of 1.88 meters came out.
In 1938, a single-sided corrugating machine with a width of 2.2 meters was launched.
In the 1940s, the continuous rotary single-sided corrugating machine came out. In the 1950s, driven by the rapid development of the world economy and trade, a double-sided corrugated cardboard production line that connected multiple processes appeared. The width of the cardboard production line in the initial period is generally only 1000~1600mm, and the running speed is only 60~100m/min. After the advent of single-sided corrugated cardboard, after 64 years of development, in 1950, the double-wafer composite corrugated cardboard assembly line was born. In 1959, a mechanically linked corrugated board production line was created.
(4) The rapid development period of corrugated board production line
After the 1960s, corrugated packaging technology has made great progress, and some more advanced technical equipment have been launched one after another, and many high-efficiency and highly automated corrugated cardboard production lines have appeared. In 1968, a width of 2.2 meters and a speed of 212 meters were introduced. /min for a modern corrugated board line with a single-sided corrugator without guide jaws and a "double chopper" cross-cutting machine. Since then, the technological progress of the corrugated board production line has entered a period of rapid development. With the vigorous development from 1970 to 2000, the carton factory was able to reduce costs and increase profits. Good operation coupled with advanced corrugated lines increased corrugated box production from 10,000 square meters per hour in 1972 to 17,000 square meters per hour in 1985, and even reached 30,000 square meters per hour in 2000. In addition, some machinery suppliers design their machines as components so that when equipment is upgraded, operator disruption to production is minimized and production costs are reduced. In addition, the rapid development of digital electronic technology has an increasingly obvious impact on various industries, and is applied to the entire tile wire processing process.
In the 1980s, as machinery manufacturers became more experienced and their design concepts became more stable and mature, those new products introduced in the 1970s were continuously improved. Over the next 10 years, machinery suppliers saw this as an opportunity to increase product yield and quality, and doubled their focus on research and development of new machines. Improved web tension control on the tile line and precise alignment of the web became another goal of theirs. From the 1980s to the 1990s, machinery suppliers and carton plant operators were immersed in solving these technical challenges and the central control of the corrugated box processing process. Although many technologies were in the experimental stage in the 1980s, and experimental errors occurred from time to time, some progress had been made in improving the performance of gluing and gluing and its control. Coupled with improved and more precise drive motor control and mechanical design and the application of various new materials, paperboard quality and production speed have been greatly improved.
In the mid-1980s, driven by the two emerging technologies of mechanical design and electronic control, there was a new wave of innovation in the field of tile wire production. The new tile line runs faster, with wider width and more reliable performance, and improves productivity with the same or less labor. Because it is equipped with an automatic detection system for defective products and an automatic control system for equipment maintenance, the rejection rate is high. In order to reduce, product quality has been greatly improved.
These breakthroughs benefit from improvements in the precision and strength of mechanical hardware, as well as breakthrough innovations brought about by new digital electronic controls, stepper motor drives and frequency-controlled AC drives. At the same time, people have a deeper understanding of the physical and chemical processes in the corrugated process, the reasons for the vibration of the machine and the control inside the machine.

At present, there are generally three types of equipment for manufacturing corrugated cardboard and corrugated boxes in my country. One is the traditional stand-alone. It is a corrugating machine that forms corrugated base paper into a corrugated paper. A glue machine that glues the face paper, lining paper, core paper and corrugated corrugated paper to complete the manufacturing process of corrugated board. It is matched with a single machine to manufacture corrugated boxes. The equipment combined with corrugated paper also needs to complete the processes of batching, cutting, printing, splicing, slitting, grooving, corner cutting and forming. The whole single-machine assembly line has many equipment and process links, the product quality is not well controlled, and the consumption is high. The other is a single-sided corrugated paper machine, which first produces single-sided corrugated cardboard, and then processes it through a single-machine glue car to produce different structures and corrugated cardboard. The single-sided corrugated paper machine is a semi-automatic production line composed of a reel bracket, a single-sided corrugated machine and a rotary bracket type paper cutter. It has the characteristics of high efficiency, good product quality and strong adaptability. Another is to use the corrugated cardboard automatic continuous production line to complete. Various equipments organically combine the entire corrugated board production process to make it continuous production. The traditional method of combined production of many single machines not only has high production efficiency and low labor intensity, but also centralized control of operation, which is simple, safe and low in noise; the most important thing is the high quality of corrugated cardboard produced. The corrugated and corrugated shapes are standardized and standardized. The packaging containers produced by this equipment are neat, beautiful and flat. Appearance and physical properties are superior to products produced by single machine or combined single machine linkage line.
