Feeding mechanism of baking equipment for powder metallurgy

Abstract

The invention discloses feeding mechanism of baking equipment for powder metallurgy. The feeding mechanism comprises a rack and a conveyor belt assembly, wherein the conveyor belt assembly comprises afeeding roller, a discharging roller, and a conveyor belt; the feeding roller and the discharging roller are horizontally arranged on the rack and sleeved by the conveyor belt; the conveyor belt circularly turns along with the rotation of the feeding roller and that of the discharging roller, so that a feeding section positioned at the upper part, a returning section positioned at the lower part,and turning sections wound around the feeding roller and the discharging roller can be formed; the discharging roller is mounted on the rack through a bearing; the feeding roller is connected with atensioning mechanism; a conveyor belt outer surface cleaning mechanism is arranged at the end where the discharging roller is positioned; and a conveyor belt flattening mechanism is arranged in the returning section. By adoption of the feeding mechanism disclosed by the invention, the following beneficial effects are achieved: the tension, the flatness and the outer surface cleanliness of the conveyor belt can be kept; the effective operation of the conveyor belt can be kept generally; the normal work of the conveyor belt can be kept; the service life of the conveyor belt can be prolonged; andthe reliability of the whole feeding mechanism can be improved.

Description

technical field [0001] The invention relates to the field of powder metallurgy devices, in particular to a feeding mechanism for powder metallurgy baking equipment. Background technique [0002] Powder metallurgy is a molding technology that has rapidly matured and been widely used in recent years. In order to control product quality, metallurgical powder raw materials must be pretreated. Due to the small powder particles and large specific surface area, it is easy to absorb water molecules, so baking is a common dehumidification process. In the production workshop, the raw material powder stored in the barrel is transported into the baking equipment through the feeding device and the transportation device. The conveyor belt is a common transportation device, which uses a closed conveyor belt as the traction part and the carrying part. The conveyor belt device has the following problems: First, after long-term loading and operation, the conveyor belt is easily stretched a...

AI Technical Summary

Problems solved by technology

The conveyor belt device has the following problems: First, after long-term loading and operation, the conveyor belt is easily stretched and deformed, and the conveyor belt cannot be tensioned when idling, resulting in a decrease in transmission efficiency; The sides are easy to warp and the tension is uneven, which leads to a decrease in transmission efficiency, affects loading and transportation, reduces the life of the conveyor belt and even causes accidents; in addition, because the powder particles are easily adsorbed on the surface of the conveyor belt, the unloading is not complete, which not only wastes raw materials, but also easily causes accidents. Cause dust to fly in the workshop, pollute the environment and bring safety hazards
