What Should You Know Before Purchasing a Corrugator Conveyor Belt?

The Importance of Corrugator Conveyor Belt

The corrugated cardboard production process covers multiple stages, including unwinding of base paper, corrugating, gluing, slitting, printing, and forming.

So, the corrugator conveyor belt plays one of the most important components of a corrugated cardboard production line. Its quality has a decisive impact on the quality of corrugated cardboard you produce and has always been a focus of attention for corrugated cardboard factories and manufacturers.

Usually, there are three core roles of the corrugator conveyor belt: continuous transport, precise positioning, and buffering connection.

Continuous transport: Operating at a constant speed, the corrugator belt can smoothly transport the cardboard from one process to the next, avoiding production interruptions and ensuring the continuity of the corrugated cardboard line.

Precise positioning: In high precision processes such as printing and die-cutting, the corrugator conveyor belt needs to work with equipment to accurately position the cardboard and ensure processing accuracy.

Buffering connection: When different devices operate at different speeds, the corrugator conveyor belt can create a buffer zone through tension adjustment to balance the rhythm of each stage.

Essential Characteristics of Corrugator Conveyor Belt

High Strength Load Bearing

Corrugated cardboard (especially multi layer cardboard) can weigh several kilograms per sheet, placing extremely high demands on the load bearing capacity of conveyor belts during bulk transport. High quality conveyor belts typically use a polyester fiber skeleton or Kevlar reinforcement layer, combined with a highly elastic rubber base material. This is capable the corrugator conveyor belt withstanding  50 to 100 kg per square meter while maintaining smooth transport.

Anti Slip & Wear Resistant Properties

The cardboard surface is smooth and easy to slide, so the conveyor belt surface often features a diamond pattern or grid design to increase friction and prevent cardboard deviation.

Moisture Resistance & Temperature Resistance

The production environment may contain moisture (such as steam from the bonding process), so the corrugator conveyor belt needs to have a certain degree of moisture resistance to prevent structural aging due to dampness.

At the same time, the cardboard temperature is high in some stages (such as after drying), so the corrugator conveyor belt needs to withstand short term high temperatures of 60 to 80℃.

Customizable Corrugator Conveyor Belt

The width (ranging from 1.6 meters to 3.2 meters), speed (10 to 30 meters/minute), and connection methods of different corrugator cardboard production lines vary greatly. Professional corrugator conveyor belt manufacturers can provide customized sizes and add guide strips, baffles, or perforation designs as needed to adapt to special transmission scenarios.

Corrugator Conveyor Belt Key Technical Parameters

Air Permeability of Corrugator Conveyor Belt

Air permeability refers to the ability of air to pass through the corrugator conveyor belt structure. It is a crucial indicator of the operation of corrugated paper conveyor belts and affects the uniformity of corrugated board drying.

Choosing a suitable corrugator conveyor belt with appropriate air permeability is essential. Insufficient air permeability will prevent steam from escaping in time, causing foaming of the corrugated paper and affecting the bonding effect of the material. But, if the air permeability is too high, it will also lead to a decrease in the support strength of the conveyor belt, making the corrugated cardboard more prone to deformation.

Mechanical Strength

Mechanical strength refers to the ability of a corrugator conveyor belt to resist tension, impact, and fatigue during operation. Insufficient mechanical strength can lead to various problems, such as belt stretching, joint breakage, or edge cracking.

Mechanical strength determines whether the corrugator belt can maintain dimensional stability under dynamic production loads.

Corrugator Conveyor Belt Heat Resistance

In the high temperature zone of a corrugated paper machine, temperatures can typically reach 120°C to 200°C. This requires the corrugator conveyor belt to maintain its structural and performance stability under such continuous high temperatures, without deforming or hardening due to the heat.

Seam Integrity of Corrugator Conveyor Belt

You should understand that in corrugator conveyor belts, the seams are the structural weak points of the entire belt.

During the operation of the corrugator conveyor belt, structural asymmetry, insufficient strength, or susceptibility to humid and hot environments will all lead to problems with the belt, such as periodic belt misalignment, belt vibration, or belt breakage. All of these issues will reduce the quality of the corrugated paper produced.
