Carton machinery and equipment skills technical mechanical knowledge new commodity supporting equipment the tension imbalance of each layer of paperboard will also lead to the longitudinal warpage of paperboard. Pay attention to adjusting the transportation tension of face paper and each layer of paperboard. The paper produced by different production equipment and technology and the paper from different producing areas will have different shortening direction differences and shortening rates. The difference between the paper and stacking conditions of different incoming batches will make the moisture content of the paper different. The old conveyor belt will affect the moisture evaporation of the upper paperboard due to poor air permeability, and will make the upper paperboard absorb the steam from the base paperboard and cause moisture absorption and deformation. The old production line should pay attention to avoid neglecting this factor. If you know the principle and the conditioning methods on the production line, after careful investigation and careful analysis, and adopt appropriate methods for adjustment, you can clean it quickly. You must know the stable high economic operation speed of the drying channel on the production line and the normal temperature of the hot plate.

The skill level of China’s carton machinery is 20 years behind that of advanced countries, and is at a disadvantage in the competition in commodity development, function, quality, reliability and service. Packaging machinery products should be developed in the direction of multi-function and single high-speed; For candy packaging, pillow type, special-shaped and conjoined are needed. Such commodities require a series of commodity packaging to be completed on a packaging machine. Paperboard warping is a common phenomenon in the production process of corrugated paperboard. Each company has accumulated certain experience. It is necessary to determine the appropriate humidity of all levels, inner and core paper before compounding in the production process of paperboard with a stable and high economic operation speed and control it reliably.
