AI Technical Summary

Technical Problem

Existing wheel-type belt pressing devices are prone to belt slippage at the concave arc section of belt conveyors, increasing power loss and failing to effectively prevent material spillage, thus failing to meet the requirements of special working conditions.

Method used

Design a belt pressing device for the concave arc section of a belt conveyor. The main frame is arranged with a lower front and higher rear angle. It combines a front pressing pulley, a rear pressing pulley and a floating pressing assembly. The tension of the cover belt is controlled by an adjusting rod. The elastic pressing part and the floating pressing assembly make the cover belt fit with the material and provide power support.

Benefits of technology

It effectively prevents ribbon spillage, reduces tension, improves material adhesion, prevents spillage, and provides power support in the concave arc section to improve conveying efficiency.

Abstract

A belt conveyor concave arc section belt pressing device, comprising a front support frame, a belt pressing mechanism, a rear support frame arranged higher than the front support frame; the belt pressing mechanism comprises a main body frame, a front belt pressing wheel, a rear belt pressing wheel, a floating type belt pressing assembly and a covering belt; the main body frame is hinged to the top of the front support frame and the rear support frame, the front belt pressing wheel is rotatably installed at the front end of the main body frame, the rear belt pressing wheel is rotatably installed at the rear end of the main body frame, the floating type belt pressing assembly is arranged below the main body frame, and the floating type belt pressing assembly can make the covering belt always adhere to the material; a guide groove is arranged on the main body frame, and an adjusting rod for controlling the rear belt pressing wheel to move along the guide groove is arranged on the main body frame. The front belt pressing wheel and the rear belt pressing wheel drive the covering belt to form a circular rotating track, and the floating type belt pressing assembly presses the covering belt downward, so that the covering belt always adheres to the material on the conveying belt, and the belt pressing and the prevention of material scattering can be realized. A belt conveyor is also provided.
