Introduction to Conveyor Belts
Definition and Overview
A conveyor belt, often termed as a transport belt, is a pivotal product in the realm of material handling, renowned for its vital role in efficiently carrying and transporting materials within a belt conveyor system. Crafted meticulously by blending rubber with fibers, metals, and other structural materials, or by combining plastics with fabrics, it stands as a cornerstone in the architecture of automated production lines.
Development History
- The evolutionary journey began with its predecessor, the transmission belt, and witnessed the emergence of canvas belts in 1795.
- By 1858, the integration of reinforced skeletons marked a significant advancement, leading to the debut of the two-layer-skeleton rubber conveyor belt in 1868.
- 1892 was a landmark year, as it addressed the trough-forming challenge of rubber conveyor belts. This breakthrough was followed by the introduction of synthetic fibers, which remarkably enhanced the trough-forming capability and tensile strength, and saw the invention of flame-retardant belts.
- A leap into the late 1920s brought about the advent of aramid belts, revolutionizing the feasibility of ultra-long-distance transportation.
Basic Structure
- Cover Layer: Comprised of an upper and lower rubber layer, this essential component is adhered around the belt core. Rubber formulations are meticulously chosen based on operational requirements, offering properties such as oil-resistance, abrasion-resistance, cold-resistance, flame-retardance, heat-resistance, and ozone-resistance.
- Belt Core Layer: The backbone of the conveyor belt, it carries the load with its robust construction. Depending on the desired belt strength, it can be crafted from cotton canvas, nylon, polyester, aramid fabrics, or even steel wire ropes, available in single-layer or multi-layer configurations.
- Isolation Layer: This layer is integral for bonding the belt core, with formulations tailored to match the specific belt core materials utilized.
Basic Functions
Within an automated production line, the conveyor belt seamlessly transfers workpieces between workstations for various processing operations. When utilizing a pallet fixture, not only does it transport the workpiece sequentially to each workstation, but it also dutifully returns the pallet fixture from the line's end back to its starting point. Its design and performance are critical, directly influencing the production efficiency of the automatic line. Thus, enhancing the reliability of the conveyor device is paramount to ensuring the seamless operation of the production line.
Classification
- By Style: Ranging from roller-type variations (including free-conveying and driven roller types), to chain-types (ideal for returning pallet fixtures to the start of the line, operable intermittently or continuously), and step-types (which intermittently move workpieces or fixtures with mechanical or hydraulic assistance).
- By Purpose: Encompassing general-purpose belts and those designed for specialized functions such as flame-retardant, anti-static, heat-resistant, chemical-resistant, oil-resistant, low-temperature-resistant, and food-grade applications.
- By Surface Shape: Spanning a diverse array of configurations including planar, trough, deep trough, corrugated side-wall, partition, round tube, flat tube, and embossed types.
- By Belt Core Type: Categorized into fabric types (such as cotton canvas and synthetic fibers), and steel types (comprising steel wire ropes, steel fibers, steel strips, and steel wire cords).
- By Strength: Offering a spectrum of strength levels from low-strength (<300kN/m), to medium-strength (300 - 1250kN/m), and high-strength (>1250kN/m).
- By Working Department: Our conveyor belts are meticulously engineered for diverse applications. In underground mining scenarios, they are predominantly high-strength and flame-retardant, ensuring both safety and reliability. For open-pit mining, the preference is for steel wire cord reinforced, high-strength belts tailored for robust applications. On construction sites, versatile low-to-medium strength belts cater to various demands. Within factories, we offer an array of low-to-medium strength belts, each designed for specific purposes. Agricultural engineering benefits from our cotton canvas and synthetic fiber options, favoring low-to-medium strength uses. The transportation industry, including airports, relies on our general-purpose planar belts to ensure seamless operations. The packaging industry thrives on our low-strength general-purpose belts, while passenger transportation is supported by our durable general-purpose and steel-type belts, designed to meet rigorous demands.
