AI Technical Summary

Technical Problem

Existing powder coating methods suffer from component segregation and unevenness. Furthermore, dual-drive conveying is costly and prone to accumulation, resulting in uneven diaphragm thickness. It also fails to achieve simultaneous conveying and slag removal, thus affecting the quality of dry electrodes.

Method used

A gravity-type automatic powder conveying device was designed, including a buffer tank, a feeder, a screening component, a smoothing component, and a baffle component. Through the combination of gravity feeding, screening, and smoothing components, uniform material conveying and slag removal are achieved. It is suitable for pressure rollers of different widths and uses a limit component to automatically adjust the size of the discharge port, thereby improving the degree of automation.

Benefits of technology

It achieves uniform material spreading, reduces conveying costs, improves the thickness uniformity and continuity of the diaphragm, enhances product quality, has a wide range of applications, and a high degree of automation.

Abstract

This utility model belongs to the technical field of conveying devices, specifically relating to a gravity-type automatic powder conveying device. The utility model includes a frame, a buffer tank mounted on the frame, a feeder mounted below the buffer tank, a screening component mounted below the feeder, a smoothing component and a baffle component mounted below the screening component, and a controller for controlling the operation of each component. The feeder's inlet is sealed to the buffer tank's outlet, and the screening component's inlet is sealed to the feeder's outlet. The screening component includes a screening box, a screen, a power component, and two limiting components symmetrically mounted on both sides of the screening component. By arranging the buffer tank, feeder, screening component, smoothing component, and baffle component sequentially from top to bottom, this utility model saves floor space, allows materials to be conveyed downwards under gravity, accelerates material conveying speed, and saves conveying costs.
