AI Technical Summary

Technical Problem

Traditional coating equipment cannot guarantee the consistency of extrusion speed in the coating width direction for each type of slurry when coating different slurries, which affects the coating quality.

Method used

A coating die head is designed, including a first die head and a second die head that are set separately to form a receiving cavity. An adjustable flow-delineating component and the cavity wall define the flow channel. The shape of the flow channel can be adjusted to match slurries of different viscosities to ensure the consistency of extrusion speed.

Benefits of technology

By adjusting the position, shape, and number of the turbulence-disrupting components, the extrusion speed of slurries with different viscosities was made consistent in the coating width direction, thus improving the coating quality.

Abstract

This application relates to a coating die and a coating machine, comprising: a coating body including a first die and a second die separately disposed therefrom, the first die and the second die being joined and defining a receiving cavity; a coating inlet and a coating outlet communicating with the receiving cavity are respectively opened at opposite ends of the coating body; a flow-deflecting component defining a flow channel with the cavity wall of the receiving cavity; the flow-deflecting component is adjustablely disposed in the receiving cavity. With the above configuration, since the flow-deflecting component is adjustablely disposed in the receiving cavity, the flow channel defined by the flow-deflecting component and the cavity wall of the receiving cavity varies with the adjustment of the flow-deflecting component in the receiving cavity, thereby meeting the requirements for coating slurries of different viscosities.
