Description

[0002] As an important part of modern logistics and packaging field, the production quality and efficiency of corrugated box directly affect the smooth operation of the whole industry chain. In the production process of corrugated box, the paper feeding device undoubtedly occupies a pivotal position. It is responsible for accurately and stably feeding corrugated paperboard into subsequent processing links such as printing, slotting, line pressing, die cutting, etc., and the performance of the paper feeding device is directly related to the appearance, quality and production efficiency of the carton.

[0003] The existing paper feeding device has poor stability when conveying corrugated paperboard, and is easily affected by factors such as paper thickness, material, humidity, etc., resulting in paper deviation and wrinkles. The thickness of corrugated paperboard has a tolerance, and the traditional paper feeding device is difficult to adapt to the stable conveying of paperboard of different thickness. When the paperboard is thicker, the frictional resistance increases, and it is easy to be stuck, while when the paperboard is thinner, the uneven stress leads to unstable conveying. Different materials also affect the conveying effect, for example, high-density paperboard is hard and has low bending degree, but low-density paperboard is soft and easily deformed under external force, which reduces the conveying accuracy. Changes in humidity further exacerbate this problem. After the paperboard is soaked, its flexibility increases, but its strength decreases, and it is easy to deform or wrinkle during conveying, which reduces the accuracy of subsequent printing and die cutting.
