Introduction to Conveyor Belts
Definition and Overview
A conveyor belt, often referred to as a transport belt, is an indispensable component in the realm of modern industrial transportation within a belt conveyor system. Crafted ingeniously by blending rubber with robust materials like fiber and metal, or using plastic and fabric, it serves as the lifeline of automated production lines, facilitating seamless material flow.
Development History
- Originating from simple transmission belts, the journey began with canvas belts in 1795.
- The introduction of reinforced skeletons in 1858 marked a significant leap, leading to the creation of two-layer-skeleton rubber conveyor belts by 1868.
- By 1892, advancements resolved the trough-forming challenges of rubber conveyor belts. The adoption of synthetic fibers further enhanced their strength, culminating in the invention of flame-retardant belts.
- The late 1920s witnessed the advent of aramid belts, revolutionizing the industry by enabling ultra-long-distance transportation.
Basic Structure
- Cover Layer: Comprised of upper and lower rubber layers enveloping the belt core, this layer is critical. Tailored rubber formulations offer oil-resistance, abrasion-resistance, cold-resistance, flame-retardance, heat-resistance, and ozone-resistance, selected based on service needs.
- Belt Core Layer: Acting as the backbone, this layer bears the primary load. Depending on required strength, options include cotton canvas, nylon, polyester, aramid fabric, or steel wire rope core, available in single or multi-layer configurations.
- Isolation Layer: Essential for bonding the belt core, it uses specific formulations to complement various belt cores.
Basic Functions
Within an automatic production line, the conveyor belt is vital for transferring workpieces between successive workstations. When pallet fixtures are employed, they convey both the workpiece and the fixture, which then returns to the line's start. The belt's structural integrity and performance are pivotal, directly influencing production efficiency, and ensuring the reliability of this device is crucial for smooth operational continuity.
Classification
- By Style: Comprising roller-type (free or driven), chain-type (for returning pallet fixtures, functioning either intermittently or continuously), and step-type (moving items with mechanical or hydraulic assistance).
- By Purpose: Encompassing general-use belts and those designed for specialized needs such as flame-retardant, anti-static, heat, chemical, oil, low-temperature resistance, and food-grade applications.
- By Surface Shape: Featuring designs such as planar, trough, deep trough, corrugated side-wall, partition, round tube, flat tube, and embossed types.
- By Belt Core Type: Including fabric types like cotton canvas or synthetic fibers, and steel types such as wire rope, steel fiber, strip, or cord.
- By Strength: Ranging from low-strength (<300kN/m), medium-strength (300-1250kN/m), to high-strength (>1250kN/m).
- By Working Department: Encompassing a diverse array of sectors, our products shine in underground mining, championed by high-strength, flame-retardant belts specifically designed for subterranean safety. In open-pit mining, the emphasis is on reinforcement with steel wire cords for unmatched durability. Construction sites benefit from low to medium-strength solutions tailored for diverse demands. Within factories, our belts cater to a spectrum of applications with both low and medium-strength options. Agricultural engineering sees innovation through cotton canvas and synthetic fiber belts, ensuring reliability. In the transportation industry, including airports, our general-purpose planar belts are indispensable. The packaging industry relies on our low-strength general-purpose belts, while in passenger transportation, we offer versatile solutions, including steel-type belts, to meet varied needs.
