Corrugated board pressure line problem solving - precise size (on)

Due to deviations in manufacturing size adjustments that have not been issued in accordance with production orders, or inaccurate longitudinal dimensions due to the lack of fixation of the slitting pressure reel, and inaccurate horizontal cutting due to vehicle speeds and conveyor belts, they have a great impact on board production. the quality of. Therefore, the accuracy of the pressure lines and dimensions of the cardboard can be grasped to ensure that the user is provided with a high quality carton. Next, the journal will provide you with solutions to problems in the press line. Because, precisely made of high-quality corrugated cardboard.

The second precise size brings high quality corrugated cardboard

In the structural design of the corrugated box, it is determined according to the manufacturing equipment used, the different production processes, the different types of corrugated paper used, and the types and properties of the contained products. Only the structure of all corrugated boxes is grasped. , Size-related content, can be manufactured to protect the goods, beautify the corrugated boxes. Under the condition that the external size of the corrugated cardboard box is determined, the internal length of the container is different, that is, the internal effective length is different. In general, the inside and outside width of the box always differ by two cardboard thicknesses.

The inner diameter of the carton is generally affected by the following factors

â—†Maximum outside diameter of the product and number of assembled products â—†Characteristics of packaged goods â—†Consider equipment limitations â—†Arrangement of packaging â—†Relevant dimensions of box liner and cushioning articles

Corrugated box size calculation formula (see figure)

In the formula:
Xi--Carton Inner Diameter (mm)
Xmax--Package Maximum Outer Diameter Size (mm)
Nx - number of wrappers arranged in a certain direction in the carton d - wrapper tolerance factor K - wrapper inner diameter size correction factor (adding a lot) (mm)
Total thickness of T-grid or cushioning The above formula is a general formula for the inner diameter size of a corrugated box.

For a one-piece package with a lining or cushioning, and a one-piece package with no lining or cushioning, the expression of the inside diameter of the carton is:

The tolerance factor of the packaging (adding a large amount) mainly considers that a certain degree of protrusion occurs in the inner packaging, so it is also called the clearance coefficient of the middle packaging. (See Table 1)

Corrugated carton manufacturing size design calculation

Corrugated box manufacturing size is the box size of the blank. Its value should be larger than the inner diameter size, which is the basis for calculating and designing the outer diameter size. If only from the geometric considerations, according to the size of the inner diameter of the material, the resulting carton volume is likely to be less than the required size of the product packaging, and ultimately scrapped.

Therefore, when calculating the manufacturing dimensions of corrugated boxes, it is also necessary to consider various factors such as processing methods, materials, cassettes, and boxes.
