Description

Track type corrugated cardboard

The present invention relates to a corrugated cardboard, in particular to a random and windable property, which can be cut into various sizes or shapes according to actual needs, and is suitable as a packaging cushioning material, heat preservation or heat insulation material, protective pad, .. . Materials such as various uses.

The conventional corrugated board is a board made of surface paper and corrugated paper formed by processing corrugated sticks of the machine. It is generally divided into two types: single corrugated cardboard and double corrugated cardboard, which are classified according to the size of corrugated. : Five types of A, B, C, E, and F.

The paper is pressed into a corrugated shape during the production process, and the final corrugated cardboard will provide cardboard elasticity, flat compressive strength, and affect the vertical compressive strength and other properties. The requirements for corrugated paper include that the paper should be flat, the thickness should be consistent, and there should be no paper defects such as wrinkles, cracks and holes. Otherwise, the production process is prone to failure and affects product quality.

Corrugated paperboard has a significant growth due to its light weight and low cost, wide range of uses, ease of manufacture, and the ability to recycle or even reuse. By the beginning of the 20th century, it has become a comprehensive level of generalization, promotion and use of all kinds of commodity packaging materials. Since packaging containers made of corrugated cardboard have unique properties and advantages for beautifying and protecting the interior goods, they have achieved great success in competition with various packaging materials. It has become one of the main materials for making packaging containers that have been used up to date and are rapidly developing.

Corrugated cardboard is made of paper, paper, core paper and corrugated paper processed into corrugated corrugated. According to the requirements of commodity packaging, corrugated cardboard can be processed into single-faced corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer corrugated paperboard. Single-faced corrugated cardboard is generally used as a lining protective layer for commercial packaging or as a lightweight backing sheet to protect the goods from shock or impact during storage or transportation; three-layer and five-layer corrugated cardboard are commonly used in making corrugated boxes. Many merchandise packages are beautifully packaged in three or five layers of corrugated cardboard. Seven-layer or eleven-layer corrugated cardboard is mainly used for making packaging boxes for electromechanical, furniture, locomotives, and large household appliances. In a specific product, the corrugated cardboard combination can be used to make the inner and outer casings, which is convenient for production and convenient for the storage, storage and transportation of the goods. In recent years, according to the needs of environmental protection and the requirements of relevant national policies, the packaging of such corrugated cardboard products has gradually replaced the trend of wooden packaging.

At present, there are four types of corrugated shapes commonly used in the world, which are A-type C, C-type 楞, B-type E and E-type 楞. Corrugated cardboard made of type A enamel has good cushioning property and a certain elasticity, and type C 楞 is second to A. However, the stiffness and impact resistance are better than that of the A-type crucible; the B-type crucible has a high density of arrangement, the surface of the corrugated cardboard produced is flat, and the bearing pressure is high, which is suitable for printing; the E-shaped crucible is thin and dense, and presents its just strength.

The corrugated shape of the corrugated cardboard constituting the corrugated cardboard is divided into a V shape, a U shape, and a UV shape. The characteristics of the V-shaped corrugated waveform are: the flat anti-pressure value is high, the amount of the adhesive is saved during use, and the corrugated base paper is saved. However, the corrugated cardboard made of this corrugated corrugated board has poor cushioning properties, and the corrugated fabric is not easily restored after being pressed or subjected to impact.

The U-shaped corrugated waveform is characterized by a large rubber area, a firm bond and a certain elasticity. When subjected to an external force, it is not as fragile as a V-shaped cymbal, but the plane expansion pressure is not as strong as a V-shaped 楞.

According to the performance characteristics of the V-shaped U and the U-shaped 楞, UV-shaped corrugating rolls made by combining the advantages of both are generally used. The processed corrugated paper not only maintains the high pressure resistance of the V-shaped cymbal, but also has the U-shaped 楞 high bonding strength and a certain elasticity. At present, corrugated rolls of corrugated board production lines at home and abroad use this UV-shaped corrugated roll.

However, no matter which shape is formed, the conventional corrugated board is flat after being manufactured. When it is stored or transported, it must be cut into a specific size in advance, and therefore, according to the actual needs of the user. The arbitrariness of cutting is insufficient.

The purpose of the present invention is to provide a corrugated cardboard which can be wound up, which has higher mobility for storage or transportation, and can be cut into various sizes or shapes according to actual needs and has better randomness.

The feature of the present invention is that the corrugated paper is formed into a substrate having a suitable thickness, and one side of the substrate is formed with a plurality of ridges parallel to each other, so as to have a winding function and a similar track shape, and then affixed to the ridges. Combine the surface paper to form a corrugated cardboard.

The technical means for creating the corrugated cardboard comprises a corrugated paper and a surface paper, wherein the corrugated paper is continuously formed on one side of the forming roller as a ridge having a plurality of protrusions and parallel to each other, and the ribs are between the substrates, so that The corrugated paper is formed into a windable crawler shape which is attached to the top of the corrugated paper to form a corrugated cardboard.

In order to obtain the effect of winding the corrugated cardboard under sufficient conditions, the distance between the two ridges is a pitch, and the optimum range of the pitch is 10 mm to 14 mm.

Similarly, in order to make the corrugated board obtain sufficient strength, The effect of the winding is that the height of the ridge formed on the upper surface of the substrate to the top surface of the ridge is 1.8 mm to 2.2 mm.

In order to provide the corrugated board of the present invention with good windable properties, the preferred thickness of the substrate ranges from 0.3 mm to 0.5 mm.

Based on the fact that the ridge formed on the corrugated cardboard has sufficient strength, the side end of the ridge is set to be a relatively narrow upper and a relatively wide lower trapezoid shape, and the upper width and the lower width of the ridge A preferred ratio is 0.5 to 0.9.
