AI Technical Summary
The existing conveyor belt emergency stop protection device lacks early warning function, which means that when the hopper overflows, it cannot remind the operator to adjust the conveying rhythm in time, which can easily lead to production interruption.
An emergency stop protection device for conveyor belts was designed to prevent hopper overflow. When the hopper is full, the emergency stop button is pulled to cut off the power to the conveyor belt through mechanical triggering. The device also triggers an alarm by driving a motor to engage a gear and rack. Combined with a dust removal mechanism, the device purifies the working environment.
This system enables timely stopping of the conveyor belt when the hopper is full, reducing production interruptions, improving the reliability and safety of the equipment, and purifying the working environment through the dust removal mechanism.
