AI Technical Summary
Technical Problem
Existing coating dies cannot dynamically adjust the internal pressure of the cavity, resulting in uneven coating and thick edges, making it difficult to meet the needs of different coating widths.
Method used
An adjustable coating die head is designed. Through the detachable connection of the upper die head, the gasket assembly and the lower die head, the width of the discharge trough is dynamically adjusted by the adjustment block and the pressure sensor to achieve pressure uniformity and avoid uneven slurry and thick edge phenomenon.
Benefits of technology
It improves coating efficiency, reduces the complexity of manual operation, and enables dynamic adjustment of the pressure inside the coating die head, ensuring coating quality and precision.

Abstract
本发明提供了一种可调节涂布模头，包括依次可拆卸地连接的上模头、垫片组件和下模头，下模头包括下模头壳体，下模头壳体的靠近垫片组件的一侧设置有出料腔；垫片组件包括：垫片基体，其上设置有沿第一方向依次连接的连通槽和出料口，出料口位于连通槽靠近待涂布工件的一侧，连通槽在第二方向上的宽度大于出料口在第二方向上的宽度；两个调节块体，沿第二方向可相互靠近或远离地设置在连通槽内，以将连通槽分隔为与出料口连通的出料槽体和分别位于出料槽体的相对两侧的两个侧部槽体，以调节出料槽体在第二方向上的宽度；其中，第一方向和第二方向相互垂直且均平行于垫片基体，以解决现有技术中的涂布模头无法对腔体内部的压力进行动态调节的问题。
