What is rubber conveyor belt
Rubber conveyor belt is an important part of belt conveyor that plays the role of carrying objects. It mainly transports a large number of raw materials, sharp heavy materials, dry materials or metals and other materials, and is used in coal, mining, metallurgy, chemical, construction and transportation industries. superior.
The rubber conveyor belt is structurally composed of three parts: the top cover rubber, the carcass and the bottom cover rubber. The specific thickness is determined by the actual use scene of the rubber conveyor belt. The carcass plays a role in providing strength and determining the shape of the belt body in the rubber conveyor belt. Generally, there are two types of fabric layers and steel wire ropes.
Common fabric layers are polyester, nylon, cotton, etc. The fabric layer is composed of warp and weft. The warp determines the resistance and elasticity of the rubber conveyor belt; the weft provides the rubber conveyor belt with resistance to cutting, tearing and impact.
The steel wire rope has high tensile strength, good impact resistance, long service life, small elongation, good grooving, good flexural resistance, and is suitable for making long-distance, long-distance, high-speed rubber conveyor belts
Rubber conveyor belts can be divided into: common type, flame-retardant type, energy-saving type, heat-resistant type, wear-resistant type, cold-resistant type, acid-alkali-resistant type, oil-resistant type, etc.
⒈ Avoid the idler being covered by the material, causing the rotation to be ineffective, to prevent the leakage of the material from being stuck between the roller and conveyor belt, pay attention to the lubrication of the moving part of the conveyor belt, but do not contaminate the rubber conveyor belt;
⒉ Prevent rubber conveyor belt load from starting;
3. If the rubber conveyor belt deviates, measures should be taken to correct it in time;
⒋When the rubber conveyor belt is found to be damaged locally, repair materials in time to avoid expansion;
⒌ Prevent the rubber conveyor belt from being blocked by the frame, pillars or block materials, and prevent it from being broken and torn.
1. Local wear (skin damage)
Fabric core rubber conveyor belts and steel core rubber conveyor belts are prone to such damage. The main reason is that the transfer place, the material guide trough, the failed idler and other parts are easily stuck with large material blocks. Once the rubber conveyor belt is running, it will definitely cause excessive wear of the rubber conveyor belt.
2. Partial fragmentation (penetrating injury)
Fabric core rubber conveyor belts and steel core rubber conveyor belts have such damage. When the rubber conveyor belt is transporting materials, there are often larger stones and sharper material blocks mixed in. These material blocks break through the rubber conveyor belt with a large impact force at the transition because of insufficient buffering, forming holes. If the material is mixed with sharp objects, such as iron crowbars, it is very easy to scratch the rubber conveyor belt, resulting in large-area tearing of the rubber conveyor belt.
3. Damage to the glued part
The adhesive part of the rubber conveyor belt is formed by re-lap vulcanization when the tape is installed. If the joints are not handled properly, it is easy to cause premature wear of the joints, peeling and other phenomena. If it is not dealt with in time, the damage and deterioration of the joint part will be faster, and the belt breakage accident will easily occur.
4. Longitudinal crack of steel wire rubber conveyor belt
Some steel-core rubber conveyor belts often have longitudinal penetrating scratches, which can be as long as tens of meters or even hundreds of meters. Such damages are generally called longitudinal cracks. Most of the reasons are that the sharp object is stuck in some places, such as the scraper cleaner, and the operator does not clean it up in time. After the belt runs, the rubber conveyor belt is scratched and torn over a long distance.
During the use of conveyor belts, there are also many forms of damage, such as: edge delamination, festering, defects and cracks; long-distance longitudinal tears, deep scratches, holes, large areas of wear, covering rubber drums or peeling, joints Internal defects, etc. Among them, the longitudinal tear is the most urgent, the edge damage is the most common, the inherent defects of the joint are unavoidable, and the service life after repair is the most concerned.
The commonly used repair methods for conveyor belts mainly include the following three
⒈Hot repair method: Usually, special repairers, vulcanizers and hot vulcanization materials suitable for conveyor belts are used to repair the damaged parts of the conveyor belt with equal strength “no trace”. This kind of repair can completely eliminate the damage of the conveyor belt and restore it to its original state. It is suitable for more important, long-distance, high-speed, and large-volume transportation systems. Completing this type of maintenance requires specialized equipment and professionals. The hot repair method is the most reliable and ideal method for the maintenance of rubber conveyor belts.
⒉Cold repair method: Usually, special cold adhesives, repair films and special tools for conveyor belts must be used to fill in the damaged parts of the conveyor belt to achieve the purpose of continuous operation. Obviously, this infill repair is a stopgap measure. Therefore, its main purpose is: when the conveyor belt is damaged, timely cold repair can prevent the damaged part of the conveyor belt from continuing to expand and extend, so as to effectively protect the core of the conveyor belt from damage, so as to wait and obtain Time and opportunity for repairs.
⒊Mechanical repair method: Usually, clips, nails, connecting plates and screws or metal cords and special appliances made of metal materials are used to fix or connect the damaged parts of the conveyor belt to achieve the purpose of maintaining operation. Even in many times and many occasions today, this seemingly simple, rough, and even ugly treatment method can play an emergency function and achieve twice the result with half the effort.
