Belt conveyor and belt conveyor
, widely used in household appliances, electronics, electrical appliances, machinery, tobacco, molding, post and telecommunications, printing, food and so on all walks of life, the objects of assembly, testing, debugging, packaging and shipping, etc.
Lines conveying can be selected according to the technological requirements: ordinary continuous operation, tempo run, variable speed operation and so on the many kinds of control mode;
Line body adjust measures to local conditions to choose: straight line and curve, slope line body forms such as conveying equipment including: belt conveyor is also called or belt conveyor belt conveyor and so on, is composed of rhythmic assembly line indispensable economic logistics transportation equipment.
Belt conveyor according to the transmission capacity can be divided into heavy belt conveyor such as mine belt conveyor, light belt conveyor such as used in electronic plastics, food and light industry, chemical pharmaceutical and other industries.
Belt conveyor with strong ability of conveyor conveying distance, simple in structure, easy maintenance, can easily implement procedural control and automation.
Using continuous or intermittent conveyor belt movement to deliver 100 kg goods or powder, of the following items, its high speed, stable operation, low noise, and can be sent on a downhill.
Working principle: drum of belt conveyor is mainly composed of two endpoints and tight set its closed conveyor belt [
Driven in conveyor belt, known as the driving drum drum (
The transmission drum)
Another is to change only the direction of the cylinder is called redirection roller conveyor belt movement.
Drive roller driven by the motor through reducer, relying on the driving drum and belt conveyor belt between the friction drag.
Driving drum is generally installed on the discharge end, to increase the traction, is conducive to drag.
Material feeding by feed end, on the rotating conveyor belt, relying on the conveyor belt friction drive to the discharge end of the discharge.
Scope of application can be used for horizontal transportation or tilted, use very convenient, is widely used in modern all kinds of industrial enterprises, such as: mine underground roadway, mine ground transportation system, the open stope and concentrator.
According to the conveying process requirements, can be a single delivery, can also be more than one component or with other conveying equipment to form horizontal or inclined conveyor system, in order to satisfy different layout of production line.
Transmission principle features: (1) the traction belt conveyor is passed by driving drum and the friction between tape, so you must use tape tension device taut, make the tape in the drum drum separation has certain initial tension.
2 tape on the roller run together with cargo.
Tape is a traction mechanism, and carrying institutions, there is no relative movement between load and tape, eliminate the frictional resistance in the operation of the tape with the cargo.
Because in a rolling bearing roller, adhesive tape and is rolling friction between rollers, thus greatly reduce the running resistance, thereby reducing the power consumption, increasing the distance of transportation.
For a belt conveyor, the traction transmission capacity, the size of the is decided by the tension of adhesive tape, adhesive tape on the transmission drum circumference Angle and coefficient of friction between belt and the transmission drum.
To ensure that the tape in the drive the roller belt conveyor is not sliding, normal operation, in the production practice to take corresponding measures according to different situations.
Improve the traction transmission capacity can be obtain from the following several aspects: (1) increasing the tensioning force (
Belt conveyor in running, the adhesive tape to elongation, cause the loss of the traction, so according to the situation, using properly the tension device will tape tension, increase the tension of belt, in order to improve the traction.
2 increase the coefficient of friction.
Its specific measures are: to protect the transmission roller covering wood liner or rubber gasket, to increase the coefficient of friction, less water coal on the other hand, to prevent friction coefficient decreases.
(3) increase the circumference Angle.
Mine belt conveyor due to poor working conditions, the traction force is big, so we adopt double drum drive, to increase the circumference Angle.
Belt conveyor is a kind of mechanical friction drive with continuous way transport material.
Is mainly composed of frame, conveyor belt, roller, roller, tensioning device, transmission device, etc.
It can be material in certain transportation on-line, from the original material feeding point to the final discharge point is formed between a material conveying process.
It can break bulk material transporting, can also be transmitted into items.
Except for pure material conveying, can also with various industrial enterprise production process match the process requirement, the formation of rhythmic flow process route.
Belt conveyor and belt conveyor, conveyor belt according to the principle of friction drive and movement, and is suitable for conveying is easy to take out the low grinding powder, granular, small block cut materials, or packaged materials, such as coal, gravel, sand, cement, chemical fertilizer, food, etc.
Belt conveyor at ambient temperature
Used 20 ℃ to + 40 ℃, temperature less than 60 ℃ was sent material.
The captain and assembly form according to customers' requirement, the transmission can use electric drum, also can use tape drive rack driving devices.
