一种新型逗号刮刀涂布装置的应用

Application of a New Type of Comma Scraper Coating Device

概述了传统逗号刮刀涂布装置结构、上胶工艺及应用的特点。介绍了新型逗号刮刀涂布装置的结构包括底辊、逗号刮刀辊、挡膜固定轴和导辊,底辊和逗号刮刀辊呈夹辊组设置且底辊和逗号刮刀辊之间设有涂胶间隙,两个挡膜固定轴用于固定相切于底辊两侧的挡膜,两个导辊在底辊的前后两侧用于传输基材;通过刮刀辊与底辊及两侧挡板自形成储胶区,基材由上而下运行,形成涂层面,通过刮刀辊与底辊之间的涂胶间隙控制涂层厚度,两侧挡膜使得基材的涂布边的两边留有白边,同时防止胶水渗入底辊;与传统逗号刮刀涂布装置比较具有环保、稳定、自动化程度高、效率高等优点。

The structure, the process and the characteristics of the application of the traditional comma scraper coating device are summarized. The structure of a new comma blade coating device includes a bottom roller, roller, block comma scraper film fixed shaft and the guide roller, roller and the bottom roller is provided with glue clearance comma scraper roller group arranged and clamped between the bottom roller and roller gear two comma scraper, film for a fixed film fixed axis tangent to the two side of the bottom roller the two guide roller for the transmission of material in the front and rear sides of the bottom roller; through the scraper roller and the bottom roller and both sides of the baffle since the formation of the glue storage area, the substrate from top to bottom, forming a coating surface, coating thickness control through the gap between the roller and the glue scraper bottom roller, block on both sides of the two sides of the base material coated film making the edge of the left margin, while preventing the glue into the bottom roller; compared with the traditional comma scraper coating device has the advantages of environmental protection, stability, high degree of automation, high efficiency etc..
