Idler roller driving belt type conveyor

Abstract

The invention relates to a roller driving belt conveyer, which comprises reversing rollers, bearing rollers, bearing drive rollers, return rollers, return drive rollers, a conveying belt, a structural bearing and an electric control system. The belt conveyer adopts a plurality of bearing drive rollers to directly drive the conveying belt, designs the specification, the rotating speed and the number of the required bearing drive rollers according to the carrying capacity requirement of the belt conveyer, determines whether the return rollers are required to be provided with the return drive rollers according to the design requirement of the longitudinal tension of the conveying belt, determines the number of the return drive rollers according to the design requirement of the longitudinal tension of the conveying belt, connects all the bearing drive rollers 1 and all the return drive rollers in series, and uses the electric control system to control and complete synchronized motion. The roller driving belt conveyer has the advantages of simple structure, reduction of a tension device, large reduction of the tension of the conveying belt and the cost, stable operation, long service life and so on.

Description

technical field [0001] The invention relates to a belt conveyor used in the fields of metallurgy, coal, transportation, electric power, building materials, chemical industry, light industry, grain, machinery, storage and the like, in particular to a belt conveyor driven by rollers. Background technique [0002] The belt conveyor is a device used to convey various bulk materials and finished items. It is generally composed of a drive roller, a reversing roller, a load roller, a return roller, a conveyor belt, a structural support and an electrical control system. The drive control It is mainly driven by the transmission drum. Generally, there are single-drive, double-drive or triple-drive drums to realize functions such as starting, running, and stopping (including emergency stop). The working characteristics of the driving mechanism are: the motor is connected to the reducer (including brake, reverse stopper) to drive the transmission drum, and under the conduction traction ...

AI Technical Summary

Problems solved by technology

Generally, under the action of a certain tension and wrap angle of the conveyor belt, the drive roller operates by friction to overcome the various resistances of the conveyor. This driving method requires the conveyor belt to have a tensioning device, and the conveyor belt should have a large Longitudinal tensile strength makes the belt conveyor have the disadvantages of complex structure, large volume, high weight, high conveyor belt cost and high maintenance rate
