Carton machinery and equipment skills and common sense of process machinery new commodity supporting equipment the tension imbalance of paperboard layer will also lead to longitudinal warpage of paperboard. Pay attention to adjusting the conveying tension of face paper and paperboard layer. The paper produced by different production equipment and technology and the paper from different producing areas will have different shortening direction and shortening rate. Buying different batches of paper and stacking conditions will make the water content of paper different. The old belt will affect the water evaporation on the upper plate due to poor ventilation, and will also make the upper plate absorb the steam of the bottom plate and absorb moisture and deform. The old production line should pay attention to avoid the negligence of this element. If you know the synchronization principle and method of each recuperation on the production line, after careful investigation and analysis, and adopt appropriate methods for adjustment, you can sweep quickly. You must know that the production line is used to bake high economic operation speed at room temperature with stable road surface and hot plate.

From the technical level of China’s  carton machinery from all advanced countries, the competition in product development, function, quality, reliability and service is at a disadvantage, which makes the technical level of all 20 years backward. Packaging machinery products should develop towards multi-function and single high-speed polarization; Pillow shaped and conjoined pillows are needed on the straight board packaging, and this kind of goods are needed in a series of commodity packaging at the end of the packaging machine. Warpage of paperboard is a common phenomenon in the production process of corrugated paperboard. Each company has accumulated certain experience. All levels of paperboard production process should be determined at a stable and high economic operation speed. Appropriate humidity should be maintained and firmly controlled before core paper.
