Description

Technical Field

[0001] The utility model relates to the technical field of production transportation, in particular to a novel buffer device for a feeding section of a belt conveyor. Background Art

[0002] The belt conveyor is a transport machine that relies on the inner surface of the belt to generate friction between the rollers at both ends, and drives the conveyor belt to make periodic movements through the motor to transport objects to the designated location. It is a transport machine with a simple structure, stable rotation, and impact mitigation, and can transport materials over long distances. The feed section of the belt conveyor generally uses a whole spring roller instead of a bracket-type trough roller composed of three sections as a buffer device to buffer the impact of the feed on the conveyor belt and achieve the purpose of protecting the belt.

[0003] The entire spring roller is not linear but circular. When the spring is rotated by the friction of the conveyor belt, it is in a high-frequency and large-scale compression and stretching conversion state. This high-frequency and large-scale compression and stretching conversion easily leads to spring breakage, and the buffer device needs to replace the spring frequently, which seriously affects production efficiency and maintenance costs.
