Corrugated Cardboard Conveyor Belt: The Core Conveyor System for Efficient Production

In the modern packaging industry, the production efficiency of corrugated cardboard is closely linked to the performance of the conveyor system. As a key equipment connecting various production links, the corrugated cardboard conveyor belt directly affects the capacity and product quality of the entire production line with its stability, durability and adaptability. This article will deeply analyze the core characteristics, technical advantages and application scenarios of corrugated cardboard conveyor belts, providing references for industry practitioners.

Core Functions of Corrugated Cardboard Conveyor Belts

The production process of corrugated cardboard includes multiple links such as base paper unwinding, corrugating, gluing, slitting, printing and forming. The conveyor belt undertakes three core functions: continuous conveying, precision positioning and buffer connection:

• Continuous conveying: It transports cardboard from one process to the next stably at a constant speed, avoiding production interruptions and ensuring the continuity of the assembly line.

• 

• Precision positioning: In high-precision processes such as printing and die-cutting, the conveyor belt needs to cooperate with equipment to achieve accurate positioning of cardboard, ensuring processing precision.

• Buffer connection: When there are differences in the operating speeds of different equipment, the conveyor belt can form a buffer zone through tension adjustment to balance the rhythm of each link.

Technical Characteristics of Corrugated Cardboard Conveyor Belts

Targeting the material characteristics of corrugated cardboard (heavy weight, easy to get damp, surface needs protection), professional conveyor belts must have the following characteristics:

1. High-strength load-bearing design

Corrugated cardboard, especially multi-layer cardboard, can weigh several kilograms per sheet, requiring high load-bearing capacity of the conveyor belt during batch transportation. High-quality conveyor belts usually adopt polyester fiber framework or Kevlar reinforcement layer, combined with high-elastic rubber base material, which can bear a load of 50-100kg per square meter while maintaining stable conveying.

2. Anti-slip and wear-resistant performance

The surface of cardboard is smooth and easy to slide. The surface of the conveyor belt is mostly designed with diamond pattern or grid pattern to prevent cardboard deviation by increasing friction. In addition, the contact layer is made of wear-resistant nitrile rubber or polyurethane material, with a service life of 1-3 years (depending on production intensity).

3. Moisture resistance and temperature resistance

There may be water vapor in the production environment (such as steam in the gluing process). The conveyor belt must have a certain degree of moisture resistance to avoid structural aging caused by dampness. At the same time, the cardboard temperature in some links (such as after drying) is relatively high, and the conveyor belt needs to withstand short-term high temperatures of 60-80℃.

4. Customizable adaptability

Different production lines have great differences in width (from 1.6 meters to 3.2 meters), speed (10-30 meters per minute) and connection methods. Professional manufacturers can provide customized sizes, and install guide strips, baffles or punching designs according to needs to adapt to special conveying scenarios.

Selection and Maintenance Suggestions

Key points for reasonable selection

• Choose according to cardboard type: Lightweight conveyor belts are suitable for three-layer corrugated cardboard, while high-strength models are required for five-layer and above heavy cardboard.

• Pay attention to speed matching: The speed of the conveyor belt must be synchronized with the linear speed of the front and rear equipment, with an error controlled within ±0.5 meters per minute.

• Consider environmental factors: Prioritize water-resistant materials in humid environments, and add temperature-resistant coatings in high-temperature environments.

Daily maintenance skills

• Regularly clean paper scraps and glue stains on the surface of the conveyor belt to avoid wear caused by foreign objects.

• Check the conveyor belt tension monthly; excessive looseness may cause slipping, while excessive tightness will accelerate framework aging.

• Timely repair local wear or loose joints to avoid expanded failures affecting production.

Application Scenarios and Industry Value

Corrugated cardboard conveyor belts are widely used in:

• Corrugated cardboard production lines (full-process conveying from base paper lamination to cardboard slitting);

• Carton printing linkage lines (cooperating with printing machines and die-cutting machines to realize integrated production);

• Automated warehousing systems (stacking and transferring of finished cardboard).

Its core value lies in: improving the efficiency of each process by 15%-30% through stable conveying performance, while reducing the waste rate caused by cardboard collision and deviation (which can be reduced by 5%-8%), creating significant economic benefits for packaging enterprises.

Choosing a suitable corrugated cardboard conveyor belt is the foundation for efficient and stable production. It is recommended to cooperate with professional manufacturers for scheme design according to the actual needs of the production line, and pay attention to daily maintenance to extend equipment life and maintain optimal operating conditions.
