Application Of Web Guiding System In Belt Conveyor

[Abstract] The belt conveyor passive correction method completely solves the problem that the guiding device needs power supply, the action is not sensitive, the system is cumbersome, the maintenance and installation is inconvenient, the environment temperature is affected, the oil leakage and the like are mainly applied to the belt conveyor.

Belt conveyor rectification devices have been widely used in belt conveyors in metallurgy, chemical, electric power, coal mining and other industries. The quality of the rectification system has directly affected the normal operation and service life of the conveyor. At present, the simple mechanical rectification used on the belt conveyor and the relatively complicated four-link swing arm type rectification are passive rectification, and there is a problem that the action is insensitive and the rectification effect is not good. The passive hydraulic rectification invented in recent years, although the rectification effect is good, is susceptible to the working environment temperature. When the outdoor low temperature, the hydraulic oil has poor fluidity, which will cause slow guiding. The active hydraulic or electric alignment system is cumbersome, requires power supply, high installation cost, and is inconvenient for maintenance and installation.

In order to solve the above-mentioned defects, a passive web guide system for a belt conveyor with a sensitive action, a good correcting effect, a low installation cost and convenient maintenance can be realized. The industrial application scheme is: the passive electric rectifying device for the belt conveyor includes the conveying frame and the rectifying roller, the conveyor belt is arranged on the rectifying roller, the rotary reducer is arranged on the frame, and the rectifying roller is mounted on the rotary reducer On the output shaft, the input shaft of the reducer is connected with the guiding motor; the control box is respectively connected with the detecting switch, the generator and the correcting motor, and the two detecting wheels are mounted on the rotating shaft of the generator, and are installed near the outer end of the correcting roller. Outside.

The main working process of the belt conveyor passive guiding method is: the detection wheel with the generator is installed left and right, and its symmetry center is consistent with the conveyor center. During the operation of the conveyor, when the conveyor belt deviates from the center of the conveyor, it touches any one of the detection wheels disposed on both sides, and then drives the motor to generate electricity; at the same time, the detection switch on the corresponding side controls the rotation direction of the guiding motor through the control box. The drive rotates with the rotary reducer, and the guiding roller rotates to give the belt a lateral friction force, so that the belt center with the deviation returns to the center of the conveyor until the deviation disappears; the detection wheel leaves the belt, the generator stops generating electricity, and the correcting motor When the work stops, the rotary reducer stops at the same time and the correction ends.

The belt conveyor passive correction method completely solves the problems that the web guiding system needs power supply, the action is not sensitive, the system is cumbersome, the maintenance and installation is inconvenient, the environment temperature is affected, the oil leakage is caused, and the main application is on the belt conveyor. The most beneficial effect of this method is that its generator and detection switch are connected through the junction box and the rectifying motor. The whole system relies on two low-speed DC generators to drive the rotary reducer to drive the revolving idler roller to rotate. The passive electric rectifying device of the belt conveyor is sensitive, the overall structure is simple, easy to install and maintain, the user purchase cost is low, and the application prospect is very broad!
