Introduction to Conveyor Belts
Definition and Overview
A conveyor belt, affectionately termed the 'transport belt', serves as the lifeline for material movement within a belt conveyor system. Crafted meticulously from a combination of rubber, fiber, and metal, or optionally using plastic with a fabric blend, it stands as the cornerstone of automated production lines, driving efficiency and precision.
Development History
- It traced its origins from the transmission belt, with the revolutionary introduction of canvas belts in 1795 marking a new era.
- The introduction of reinforced skeletons in 1858 was pivotal, followed by the advent of two-layer skeleton rubber conveyor belts in 1868, setting a new standard for durability.
- 1892 was a landmark year as it addressed the trough-forming challenge of rubber conveyor belts. The subsequent adoption of synthetic fibers enhanced both the trough-forming capability and strength, leading to the innovation of flame-retardant belts.
- The late 1920s witnessed the emergence of aramid belts, unlocking the potential for ultra-long-distance transportation, and expanding the horizons of industrial operations.
Basic Structure
- Cover Layer: Encompassing the belt core, it comprises an upper and lower rubber layer. Tailored rubber formulations, offering properties like oil-resistance, abrasion-resistance, and more, are selected to meet specific service requirements, ensuring adaptability across diverse environments.
- Belt Core Layer: Acting as the robust skeleton, this layer shoulders the load, with options ranging from cotton canvas to steel wire rope cores. Depending on strength requirements, it is crafted into either single-layer or multi-layer configurations, guaranteeing resilience and strength.
- Isolation Layer: This essential bonding layer varies in formulation to suit different belt cores, ensuring cohesion and structural integrity.
Basic Functions
Within an automated production line, the conveyor belt seamlessly transitions workpieces from station to station for subsequent processing. When paired with a pallet fixture, it not only transports workpieces but also returns the fixtures back to the starting point. The structure and performance of the conveyor belt are vital for optimizing production efficiency, and enhancing its reliability is crucial for the smooth operation of automated lines.
Classification
- By Style: Options include roller-type (encompassing free-conveying and driven roller types), chain-type (ideal for returning pallet fixtures to the line's start, functioning both intermittently and continuously), and step-type (utilizing mechanical or hydraulic mechanisms for intermittent operation).
- By Purpose: Encompasses general-purpose belts alongside specialized variants like flame-retardant, anti-static, heat-resistant, chemical-resistant, oil-resistant, low-temperature-resistant, and food-grade belts, meeting a spectrum of industrial needs.
- By Surface Shape: Variants include planar, trough, deep trough, corrugated side-wall, partition, round tube, flat tube, and embossed types, catering to specific material handling requirements.
- By Belt Core Type: Encompasses fabric types (like cotton canvas and synthetic fibers) and steel types (including steel wire rope, steel fiber, and steel wire cord), each offering unique benefits.
- By Strength: Categorized into low-strength (<300kN/m), medium-strength (300-1250kN/m), and high-strength (>1250kN/m) to match the demands of various industrial applications.
- By Working Department: Our versatile range of belts serves an array of sectors, including underground mining, where high-strength, flame-retardant types are indispensable. For open-pit mining, we offer belts reinforced with robust steel wire cords to withstand extreme pressure. Construction sites benefit from our low to medium-strength belts, while within factories, a diverse selection caters to various manufacturing needs. Agricultural engineering utilizes our durable cotton canvas and synthetic fiber belts, ideal for low to medium-strength requirements. In the transportation industry, such as airports, our general-purpose, planar belts are the go-to solution. The packaging industry relies on our low-strength, general-purpose belts, while passenger transportation sectors often choose our general-purpose and steel-type belts for reliability and performance.
