热敏纸高速涂布整饰设备

Thermal Paper High-Speed Coating&Finishing Equipment

针对目前热敏纸涂布及整饰设备在适应热敏纸高速生产时存在上料辊涂料易于飞溅、涂层稳定性差及纸幅在运行过程中张力波动大等缺点,笔者基于热敏纸的应用范围及使用特性,阐述了采用新型喷射上料组合刮刀涂布器和帘式涂布器等涂布关键设备可消除涂料飞溅,并保持涂层质量稳定性;阐述了采用真空牵引装置和可控中高软辊压光机来解决纸幅张力波动和提高纸幅表面平滑度。文中所论述的新型高速热敏纸涂布机不仅使热敏纸高速和稳定的运行,而且满足纸幅涂层质量好的要求。

In view of the shortcomings of the current thermal paper coating and finishing equipment in adapting to the high-speed production of thermal paper,such as easy splashing of coating of the feeding roller,poor coating stability and large tension fluctuation of paper web in operation,based on the application scope and characteristics of thermal paper,the solution that adopting the key coating equipment such as the new spray feeding combined-blade coater and the curtain coater to eliminate coating splash and maintain coating quality stability was described.The method of solving web tension fluctuation and improving web surface smoothness by using medium vacuum traction device and controllable medium and high soft roller calender was introduced.The described new high-speed thermal paper coater can not only make the high-speed and stable operation of thermal paper,but also meet the requirements of the good coating quality.
