How does the dry-end corrugator work

Corrugated cardboard is die-cut, creased, nailed, or glued into corrugated boxes. Corrugated cardboard is one of the most widely used packaging products, and its usage has been at the top of all kinds of packaging products. This includes calcium-plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing properties, becoming the mainstay of transport packaging. Therefore the market prospect of dry-end corrugators is very big, so do you know what is the working principle of a dry-end corrugator?

corrugated machine

The corrugated machine works on the principle that the corrugated base paper is pressed into shape by the upper and lower corrugated rolls, and is then glued onto the paste by the glue roller. The face paper and the formed corrugated paper are laminated into a two-layer corrugated board at the tangent line between the pressure roller and the lower corrugated roller, and then on to the catwalk via the traction belt of the  corrugated machine to the double-sided machine part to be laminated with other single corrugated boards and face paper. The pressure roller of the new  corrugated machine is at the top, while the pressure roller of the old  corrugated machine is at the bottom. When the pressure roller is on top, the top paper is fed from above and the corrugated paper is fed from below. There is a difference in the pressure adjustment between positive and negative pressure corrugated machine. The pressure roller of a positive pressure machine is on top and the pressure roller itself has its weight, so pressure adjustment is very simple. Negative pressure machines, on the other hand, have the pressure roller on the bottom and need to rely on a certain amount of force to push the pressure roller upwards, which, combined with the self-weight of the pressure roller, makes it difficult to control the pressure, which has a significant impact on the paper's resistance to breakage.

CNC corrugator

The CNC corrugator is generally composed of the following parts: the main machine, which is the main body of the CNC corrugator, which is the mechanical components used to complete various machining. The numerical control unit, which is the core of the CNC corrugator and includes the hardware (CRT display, key box, etc.) as well as the corresponding software, which is used to input the digitized part program and to complete the transformation of the stored data of the input information, interpolation operations and the realization of various control functions. The drive unit, which is the driving part of the CNC corrugator actuator. The auxiliary device, refers to the CNC corrugator some necessary supporting components, to ensure the operation of CNC machine tools, such as cooling, lubrication, lighting, monitoring, etc... It also has programming and other ancillary equipment. When these parts are linked, the CNC corrugator can complete the machining of the corrugated cardboard.
