Processing method capable of making electric conduction roller obtain uniform coating and dip coating apparatus

Abstract

The invention provides a processing method and a dip-coated device which can lead a conductive roller to obtain uniform coating, comprising a mixing container which is internally filled by coating, a mixing shaft and a mixing vane which is driven to rotate by a motor, a coating container which is communicated with the mixing container and used for dip-coated the conductive roller and internal provided with uniformly mixed coating, a movable clamping mechanism, a movable component which is used for clamping closely the conductive roller and driving the conductive roller to move upwards and downwards above the coating container and connected with a swing arm, the swing arm, and a component which is connected with the motor and used for driving the movable clamping component to rotate; the processing method leads the mixing container and the coating container to be separated from each other; furthermore, a filter is arranged between the mixing container and the coating container, therefore, the mixed coating can be sufficiently mixed uniformly and bubbles generated due to the mixing in the coating process are avoided, thus obtaining coating with uniform consistency during the dip-coated process of the conductive roller and avoiding the error of the film thickness in the axis line direction of the conductive roller due to the non-enough coating in the dip-coated process, thereby improving the coating quality.

Description

【Technical field】 [0001] The invention relates to the processing field of conductive rollers (developing rollers) of printers and duplicators, and in particular relates to a processing method and a dipping device for obtaining uniform coating on conductive rollers. 【Background technique】 [0002] The conductive roller (developing roller, transfer roller) is a common developing component on printers or copiers. It can absorb toner and charge it, and then transfer the toner to the surface of the photoconductive drum / photosensitive drum. The existing conductive roller structure includes a roller core made of a metal conductive material. The roller core is covered with a conductive adhesive layer. The conductive adhesive layer is provided with a conductive rubber elastic body with a certain thickness. The conductive rubber elastic body The upper outer surface is covered with a conductive coating. When coating the conductive coating on the outer surface of the conductive roller ...

AI Technical Summary

Problems solved by technology

If the method of coating while stirring is used during dip coating, although a solution with uniform concentration can be obtained, a large number of air bubbles will be generated during stirring, so that the coating coated at this time has voids, which will cause quality defects.

At the same time, when the paint in the container decreases, the concentration of the paint will also be uneven, causing errors in the film thickness along the axis of the conductive roller.
