Abstract
A warning device (1) of abnormal operation of belt conveyor (2) has a pair of rotating mechanisms (10) disposed oppositely at two sides of a conveyor belt (2). The rotating mechanism (10) includes a rotating component (11) and a rotating body 12. The rotating body 12 has a fixed end (121) and a movable end (122). A pair of first sensor switches (20) is disposed on the rotating bodies (12). The first sensor switch (20) emits a first signal when activated and emits a second signal when being triggered. The rotating body (12) triggers the first sensor switch (20) when the conveyor belt (2) is abnormal. The first sensor switch (20) is triggered and emits the second signal for warning.
