AI Technical Summary

Technical Problem

The existing monitoring methods for glass raw material elevators are limited and cannot effectively compare the belt speed with the hopper frequency dynamically. Furthermore, the sensors are difficult to maintain.

Method used

It adopts a combination of photosensitive coating and photoelectric sensor to measure belt speed by measuring the change in reflectivity or transmittance of the photosensitive coating, and monitors hopper frequency by combining proximity switch to drive motor to control the operation of conveyor belt. It is equipped with transparent protective cover and detachable maintenance structure for easy maintenance.

Benefits of technology

It enables real-time monitoring and protection of conveyor belts, prevents abnormal situations from occurring, simplifies the sensor maintenance process, and improves the reliability and ease of maintenance of the equipment.

Abstract

This utility model provides a shutdown alarm device for a glass raw material hoist, relating to the field of glass production hoisting technology. It includes a frame housing, with a main roller and a driven roller rotatably connected to both ends inside the frame housing. The main roller and the driven roller are connected by a conveyor belt. Multiple hoppers are fixedly connected to the outer surface of the conveyor belt. A feeding port and a discharge port are fixedly connected to the frame housing. By driving the main roller to rotate, the conveyor belt is driven between the main roller and the driven roller. The linear speed of the conveyor belt is measured by a photosensitive coating and a photoelectric sensor, and then compared with the rotational speed of the main roller. In conjunction with a proximity switch, it provides real-time monitoring and feedback on any abnormalities such as belt slack, belt breakage, and material accumulation, effectively protecting the operation of the hoist.
