A wrap angle is too small or too small to cause friction roller rubber surface unglued
  Analysis shows that the belt slip , roll wrap angle a is small, the friction coefficient is small, the belt away from the point greater minimum tensile Fmin , the more slippery tape . Therefore, the design should be appropriate to increase between the drum and the tape around corners, in the production process , try to avoid the mixture of water and materials attached to this tape , reducing the coefficient of friction.
 2 tape tension is too small to cause the plastic surface unglued tape roller
  Belt tensioning with weight , weight distribution by adding weight to the address , add up to not slip , it should be noted that should not add too much so as not to unnecessarily excessive belt tension and reduce the life of the tape .
  Using screw tensioning device and the belt tensioner hydraulic slip tape , by adjusting the tensioning stroke to increase the tension , but sometimes not enough tension stroke , a permanent deformation of the tape , then the tape may a truncated , then vulcanized .
 3 sweeper roller unglued failures have led to
  Sweeper for cleaning conveyor belt adhesion materials. If the sweeper function failure will cause the adhesion of the material on the conveyor belt into the drum and between the particles and the resulting material is generated between the tape wear , resulting in drum unglued plastic surface , and reduce the life of the tape .
 Failure of sweeper
    1 ) sweeper installation used for some time , due to the frequent sweeper alloy head with a tape surface friction wear a certain extent , resulting in cleaner lapse.
    2 ) In the sweeping phenomenon occurring at blocking material will cause deform sweeper , sweeper with tape so that the mounting angle between a change in the sweeper failure .
 Measures to prevent failure of sweeper
    1 ) clean sweep often perform an inspection on badly worn sweeper alloy sheet for a replacement.

2 ) promptly clean up the head inside the funnel sediment material to prevent blocking materials , cleaner and adhesive tape on the mounting angle between changes , to re- adjust . Always check the bottom of the slow sweeper ; in rollers, tape and on badly worn roller, be replaced.
