Description

TECHNICAL FIELD

[0001] The utility model relates to the field of powder metallurgy, in particular to a copper tin alloy powder conveying belt cleaning device. BACKGROUND

[0002] In the production and processing of copper tin alloy powder, the conveying belt is a key material conveying equipment. Due to the fine and easy adhesion characteristics of copper tin powder, it is easy to remain on the surface of the conveying belt during the conveying process. If accumulated for a long time, not only will it cause material waste, but also it may affect the running efficiency of the conveying belt, and even cause the equipment to wear out. Therefore, the conveying belt must be cleaned regularly to ensure the continuity of the conveying process and the stability of the product quality.

[0003] The existing publication CN213355935U discloses a sodium nitrate conveying device capable of cleaning the belt, which includes a rack, a conveying belt, a cleaning roller, and a dust cover. The conveying belt is installed inside the rack, and a horizontal plate is fixed below the inside of the rack. An installation groove is formed in the inside of the horizontal plate, and a material receiving box is installed on the top of the horizontal plate. The end of the material receiving box is embeddedly installed in the inside of the installation groove. A cleaning roller is installed inside one side of the rack, and a brush is fixed to the surface of the cleaning roller. The cleaning roller is located below the conveying belt, and a guide plate is arranged on the outside of the cleaning roller. The surface of the guide plate is connected to the surface of the rack.

[0004] The existing technology sets a cleaning roller with a brush on one end or below the conveying belt to remove the residual sodium nitrate powder by the friction between the brush and the conveying belt. However, this structure has obvious drawbacks. During long-term operation, the cleaning roller and the brush surface will gradually accumulate powder, resulting in a decrease in the cleaning efficiency of the brush. As the accumulation increases, the contact pressure between the brush and the conveying belt is uneven, the cleaning effect is reduced, and manual cleaning is eventually required, which not only affects the production efficiency but also increases the maintenance cost.
