What is the working principle of belt conveyor?
The composition of belt conveyor: the components of belt conveyor are: machine head (including motor, transmission device, drum, etc.), machine body (including frame, roller), machine tail, belt, accessory device (including tension device, cleaning device, braking device, etc.). The working principle of the belt conveyor: the conveyor belt (or wire rope) is connected into a closed ring, and they are tensioned by a tensioning device, driven by an electric motor, relying on the friction between the conveyor belt (or wire rope) and the driving roller (or driving wheel). Make the conveyor belt (or wire rope) run continuously, so as to achieve the purpose of transporting the cargo from the loading end to the unloading end. The structure of belt conveyor: taking the drum-driven belt conveyor as an example, this paper briefly introduces the basic structure of belt conveyor. The main components of belt conveyor are: conveyor belt, bracket and frame, transmission device, tension device, belt storage device and cleaning device and so on. Conveyor belt, conveyor belt is not only a bearing mechanism, but also a traction mechanism. There are many kinds of conveyor belts.
According to the belt core structure material, it is divided into steel wire rope core conveyor belt, nylon core conveyor belt, cotton core conveyor belt and canvas core conveyor belt. Conveyor belts are divided into rubber belts, rubber-plastic belts and plastic belts according to the materials used in the covering layer; conveyor belts are divided into heat-resistant, cold-resistant, oil-resistant, acid-resistant, alkali-resistant and patterned conveyor belts according to their uses; and non-flame retardant belts and flame retardant belts are divided according to their flame retardancy. There are three types of commonly used conveyors, namely, ordinary conveyor belt, steel wire core conveyor belt and wire rope traction conveyor belt. Only the structure of the first two kinds of conveyor belts are introduced here. Ordinary conveyor belt. Ordinary conveyor belts can be used in fixed, rope hanging and retractable belt conveyors. The sandwich conveyor belt uses several layers of canvas as the belt core, the layers are bonded together with rubber, and then the outer surface is protected by a rubber cover. Canvas is made of cotton, nylon and other fibers or is a blend. The canvas layer is used to bear the load and transmit traction, while the rubber protective layer is used to prevent damage to the canvas layer by external objects and corrosion of harmful substances.
What are the types of conveyor belts?
1. Conveyor belts are generally classified according to whether there are traction parts or not: conveyor belt equipment with traction parts and conveyor belt equipment without traction parts.
2. There are many kinds of conveyor belt equipment with traction parts, such as belt conveyor, plate conveyor, trolley conveyor, escalator, automatic sidewalk, scraper conveyor, buried scraper conveyor, bucket conveyor, bucket elevator, suspension conveyor and aerial ropeway.
3. The common conveyor belt equipment without traction parts is roller rotating motion and screw conveyor.
Composition and characteristics of conveyor belt equipment with traction parts:
Conveyor belts with traction parts generally include: traction parts, bearing members, driving devices, tightening devices, reversing devices and supporting parts, etc. The traction parts are used to transmit the traction force, and the conveyor belt, traction chain or wire rope can be used.
The load-bearing component is used to hold and put materials, such as hopper, bracket or hanger, etc.; the driving device gives power to the conveyor, which is generally composed of motor, reducer and brake (stop); the tightening device generally has screw type and heavy hammer type, which can make the traction parts maintain a certain tension and sag to ensure the normal operation of the conveyor belt; the supporting parts are used to support the traction parts or load-bearing components, such as rollers and rollers.
The structure of the conveyor belt equipment with traction parts is as follows: the transported material is installed in a load-bearing member connected with the traction part, or directly on the traction part (such as the conveyor belt), and the traction part is connected around the end of each drum or sprocket to form a closed loop including a loaded branch for transporting material and an unloaded branch for not transporting material, and the material is transported by the continuous movement of the traction part.

What are the categories of belt telescopic conveyors?
Belt conveyor is usually used for the transportation of loose materials or finished articles. Generally, it is divided into types and types according to the technology of conveying materials and conveyors. We have sorted out four common types of belt conveyors as follows:
Please click to enter a picture description
1. Mobile belt conveyor
Mobile belt conveyor is a kind of continuous conveying loading and unloading equipment with high working efficiency, flexible movement and good mobility. The mobile belt conveyor can design the use length and lifting height according to the actual conditions such as the conveying requirements of users, and the general conveying height can reach 1.2-1.8m according to the difference of belt bandwidth and conveying length.
two。 Large inclination angle belt conveyor
Through the free retractable rubber waveform vertical “skirt” glued to both sides of the flat rubber transport belt, and with the help of diaphragms with certain strength and elasticity between the skirt to form a box-shaped bucket, so as to realize the continuous transportation of materials in the bucket, this is the high-angle belt conveyor. In general, high-angle belt conveyor is suitable for dispersed powder, particles and fine paste and liquid materials, such as coal, gravel, limestone, sand, clay, sand sintered powder, sawdust and so on.
3. Climbing belt conveyor
Climbing belt conveyor is a kind of belt conveyor which can lift objects at a large angle by adding strips, metallurgical tools, skirts and other ways on the belt. The climbing type can not only be used for ordinary material transportation, but also can meet the special requirements of oil resistance, anti-corrosion, anti-static and so on.
4. Retractable belt conveyor
As the name implies, the difference between the telescopic belt conveyor and other conveyors is that it can achieve free expansion to control the conveying length of the belt conveyor. Retractable belt conveyor can not only achieve efficient transportation, but also can be used with other conveying equipment, so it is widely used in automatic production. It is suitable for the transportation of materials with high temperature, large weight, large volume and wear, such as ash, cement clinker, iron slag, slag, limestone, coke, macadam and so on.
The above content is to explain the characteristics of common belt conveyor types and applicable scenarios, I hope it can be helpful to you!
What are the characteristics of the telescopic conveyor zy12?
The telescopic conveyor can reduce the scope of space use and can carry out loading and unloading truck transportation for any vehicle. A telescopic mechanism is added to the ordinary belt conveyor so that the belt conveyor can stretch freely in the length direction. Users can adjust the button according to their own requirements and control the length of the telescopic belt machine at any time. On the model with automatic lifting device, the user can also control the height of the end of the conveyor at any time. Telescopic belt conveyor is mainly used in vehicle loading and unloading and material transmission system with telescopic requirements. It greatly shortens the distance of manual transportation of materials, shortens the loading and unloading time, reduces labor intensity, reduces goods damage, reduces loading and unloading costs, and improves work efficiency. The telescopic belt conveyor can transport materials in both directions. Telescopic belt conveyor can be used in conjunction with other conveying equipment and material sorting system to realize the automatic production of materials in and out of warehouse or vehicle loading and unloading, especially in the tobacco industry. The working principle of the telescopic roller conveyor is the same as that of the ordinary roller conveyor, which uses the roller as the continuous transport equipment of the traction load-bearing machine. compared with the ordinary roller conveyor, it adds a belt storage device and a retractable roller device compared with the ordinary roller conveyor. when one end of the machine tail moves backward, the roller enters the belt storage device and the tail retracts; otherwise, the tail extends, so that the conveyor has a retractable performance.
An overview of the structure of telescopic conveyor the telescopic roller conveyor is divided into three parts: fixed part, non-fixed part and electric control part. The fixed part is composed of head transmission device, storage device, retractable roller device, etc.; the non-fixed part is composed of fast detachable bracket without bolt connection, tail, etc.; the electric control part is composed of control cabinet, wireless control device, intelligent telescopic length controller and so on.
What is the working principle of belt conveyor
The belt conveyor is mainly composed of two end rollers and a closed conveyor belt on the tight sleeve. The drum that drives the rotation of the conveyor belt is called the drive drum (drive drum).
Another drum that only changes the direction of movement of the conveyor belt is called a reversing drum. The driving drum is driven by the motor through the reducer, and the conveyor belt is driven by the friction between the driving drum and the conveyor belt. The driving drum is generally installed at the unloading end to increase the traction force and facilitate the drag. The material is fed by the feeding end, falls on the rotating conveyor belt, and is transported to the unloading end by the friction of the conveyor belt.
The main feature of the belt conveyor is that the fuselage can be easily retractable, with a belt storage bin, the tail of the machine can be lengthened or shortened with the advance of the coal mining face, the structure is compact, it can be laid directly on the roadway floor, and the frame is light and convenient to disassemble and assemble.
When the conveying capacity and distance are large, the intermediate driving device can be equipped to meet the requirements. According to the requirements of the conveying process, it can be transported by a single machine or by multi-unit synthesis of horizontal or inclined transportation system.
Belt conveyor is widely used in metallurgy, coal, transportation, hydropower, chemical and other departments, because it has the advantages of large transport capacity, simple structure, convenient maintenance, low cost, strong versatility and so on.
