What is The Working Principle of Corrugator Roll ?

The Working Principle of Corrugator Roll

The corrugator roller is divided into top corrugator roll and bottom corrugator roll, both of which have tooth shaped surfaces and are matched and engaged for assembly. The bottom corrugator roll is the active roll, and the shaft end is equipped with gears. The motor drives the lower corrugator roll to rotate through a reduction device. The top corrugator roll is a driven roll, which relies on the meshing transmission between the teeth of the top corrugator roll and the teeth of the bottom corrugator roll.

In order to press the corrugated paper into shape between the top and bottom corrugator rollers, a certain pressure must be applied on the top corrugateor roll. So the top corrugator roll can not only rotate around its own axis, but also move along the direction of the line connecting the axes of the top and bottom corrugator rolls. This movement is achieved by applying radial pressure to both ends of the corrugator rolls through a cylinder, causing the interlocking corrugator rolls to generate biting pressure.

Paired corrugator rolls operate in combination with coating rollers and pressure rollers on a single-sided machine, and their functions include a complete two-layer corrugated cardboard production process including ironing, gluing, gelatinization, and composite drying.

In order to ensure that the formed corrugated paper completes the gluing and composite drying process at high speed, it is necessary to make the formed corrugated paper tightly adhere to the corrugated roller profile and run at high speed. The use of claw plates or gas to tightly adhere corrugated paper to the corrugator rolls has led to the development of various paper guiding forms such as claw guide, vacuum internal adsorption, outer cover vacuum adsorption, and air cushion positive pressure.
