Powder high-precision weighing device and method thereof

Abstract

The invention discloses a powder high-precision weighing device and a method of the powder high-precision weighing device. The powder high-precision weighing device comprises a powder measuring hopperand a spiral conveyor. The spiral conveyor is arranged in an inclined mode and located on one side of the powder measuring hopper. A discharging pipe communicates with one side of the bottom of the spiral conveyor, is fixed to one side of the bottom of the spiral conveyor and is located above the powder measuring hopper. A rectangular base is arranged on the top of the powder measuring hopper, acircular groove is formed in the top of the rectangular base, a square feeding hole is formed in the inner wall of the bottom of the circular groove, and the bottom end of the discharging pipe penetrates through the circular groove and extends into the square feeding hole. The powder high-precision weighing device is reasonable in design, the discharging speed of the bottom end of the dischargingpipe can be conveniently adjusted in a remote control mode according to actual requirements, the process that a worker climbs the device to deal with the situation is not required, the tail feeding portion can be effectively, accurately and stably controlled as the previous rapid feeding operation can be guaranteed, the frequency of the phenomenon that fed materials are excessive due to the fact that the feeding speed is excessively high is reduced, the purpose that the feeding quantity is within the required range is finally achieved, and usage is facilitated.

Description

technical field [0001] The invention relates to the technical field of high-precision weighing equipment for powder materials, in particular to a high-precision weighing device for powder materials and a method thereof. Background technique [0002] When various powder processing equipment processes powder, it is often necessary to install a powder metering hopper at the feed inlet of the equipment for powder metering. The powder metering hopper is specially used for accurate metering at the entrance of powder equipment on the market. Metering equipment, which is often used with a screw conveyor, in which the screw conveyor is a feeding device used to convey materials upwards, and the lower end of the outlet nozzle of the screw conveyor is aligned with the top inlet of the powder metering hopper; For example, the vertical soybean peptide powder automatic metering and packaging machine model CB-4230 on the market also uses a screw conveyor to transport the powder by setting a...

AI Technical Summary

Problems solved by technology

[0003] The existing powder high-precision weighing device has the disadvantage that it is not convenient to remotely adjust the discharge nozzle of the screw conveyor. The speed of the material metering hopper is fast and difficult to control, (if it is too fast, it will cause too much powder feeding if it cannot be stopped in time, and the position of the powder metering hopper is relatively high, requiring workers to climb up to remove the excess powder, wh
