Belt conveyor is a kind of strongadaptability, widely used in conveying machinery. The belt conveyor has theadvantages of high productivity, long transport distance, multi-point loadingand unloading, various parts of frictional resistance, low power consumption,simple structure, stable and reliable operation, and convenient operation, andis thus widely used.
First, the working principle of the beltconveyor
1. Working principle of belt conveyor
The belt conveyor is a continuous conveyingdevice using the tape as a material carrier and a traction device. According tothe principle of friction, the belt is driven by the drive roller to transportthe material to the desired place. The belt is wound around the active rollerat the head and the redirecting roller at the rear to form an infinite belt. Theupper and lower belts are supported on the idler. The tensioning deviceprovides the belt with the necessary tension for normal operation. During work,the driving roller drives the belt through the friction between it and thebelt, and the material moves together with the belt on the belt.
Second, the belt machine deviation reason andtreatment
1. Reason:Thematerial is not correctly positioned in the feeding mouth. Treatment method:correct the position of the falling point, timely adjust or replace the fence,adjust the roller for adjusting the bias near the feeding port, or add thematerial baffle in the feeding port.
2. Reason: Materialfeed in the mouth. Treatment method: clean up the feed material in time.
3. Reason: Thebelt tension is not suitable or the tension is biased. Treatment method: adjustthe weight or tighten the screw in time and make both sides of the belt even.
4. Reasons: Localwear and tear on the rollers, head and tail wheels, reversal roller materialaccumulation or wear-resistance encapsulation. Treatment method: clean up thematerial in time; replace the drum wear-resistant plastic.
5. Reason: Theskin and the guide groove are worn out. Treatment method: replace or repair intime.
6. Reason: Careroll damage, loss, stent deformation. Treatment method: replace or adjust intime.
7. Reason: Thehead and tail wheels and belt brackets are not installed on the samecenterline. Treatment method: recalibrate.
8. Reasons: Theweather is affected by rain on the belt, localized sunlight, etc. Treatmentmethod: do a good job of protecting the rain, protecting the belt and so on.
9. Reason: Thebelt joint is not correct. Treatment method: re-vulcanized adhesive.
10. Reason: Thefoundation sinks. Treatment method: re-elevate.
Third, main damage factors of belt machine
1. The belt is easily injured by the rotatingparts such as the head and the tail wheel during the belt operation.
2. Suddenly starting to hurt people when beltconveyors are being maintained.
3. Clean up the roller on the belt whilerunning to make it easy to hurt people.
4. The belt running across the bottom lineeasy to hurt people.
5. Belt conveyor load is too large, thetransmission fluid even explosive and hurt.
6. Belt conveyor weight falling vulnerable toinjury.
7. The belt can not start up or slippery,with ankle, hand-pull, pressure pole and other methods to deal with easy tohurt people.
8. The inspection channel is uneven, miscellaneousobjects fall or slide easily hurt people.
9. Too narrow patrol access, insufficientlight, etc., can easily lead to accidental contact and wounding.
10. In the operation of the belt on a largeblock, through the roller to adjust the belt is easy to hurt when running.
