Apron roller in one installation to improve installation density; second is to always check the timely replacement of damaged idlers. For blanking gap larger buffer conveyor recommend installing air lock, buffer the buffer roller bed instead. Put forward the following points in the purchase of Notes in accordance with the buffer roller features: radial runout roller, roller flexibility, axial runout, roller dustproof, waterproof, roller axial bearing capacity, buffer roller impact properties.
(1) Temperature protection buffer roller
Belt conveyor belt friction to a temperature gauge, the detection device is installed close to the drive roller to issue over-temperature signal, after the signal received by the receiver, after 3s delay, so the operative part of moves to cut off the motor power supply, conveyor automatically stop, play a protective effect of temperature.
(2) roller speed protection group
If the conveyor malfunction, such as the motor burned, partially damaged mechanical transmission, belt or chain pull off, belt slippage, mounted on the conveyor passive parts of the accident sensor SG magnetic switch can not be closed or not closed at normal speed then the control system will be inverse time characteristics after a certain delay, the speed protection circuit functions, so that the operative part of moves to cut off the motor power supply in order to avoid accidents to expand.
