After the thermal base paper is coated with multiple layers of pigment, the functional coating in the paint is applied. Under the action of heat energy, the material becomes colored and transforms into a paper that records information—thermal paper. Based on usage, thermal paper can be categorized into "transmission paper" for fax machines, "tag paper" for food and luggage, and "printing paper" for POS machines, ATM machines, portable terminal printers, lottery tickets, tickets, boarding passes, and electrocardiograms. With the expanding application of thermal paper, its varieties are increasing, and the requirements for coating and finishing equipment are becoming more demanding. Equipment must be designed to handle stable high-speed transport lines and diverse production needs, making the design and manufacture of high-speed coating and finishing equipment highly significant.

To address the current shortcomings in thermal paper coating and finishing equipment, such as coating splashing from the feeding roller, poor coating stability, and large tension fluctuations of the paper web during operation, new high-speed coating finishing equipment has been developed. This equipment incorporates key technologies like the new spray feeding combined-blade coater and the curtain coater, which eliminate coating splashes and maintain coating quality stability. Additionally, medium vacuum traction devices and controllable medium and high soft roller calenders are used to resolve web tension fluctuations and improve web surface smoothness. This new high-speed thermal paper coater ensures the high-speed and stable operation of thermal paper production while maintaining high coating quality standards.

With domestic jet feeding combination scraper coaters, curtain coaters, vacuum traction rollers, and controllable medium and high soft roll calenders as key components, the successful development and application of this coating finishing equipment have significantly improved thermal paper production. The equipment addresses issues like unstable coating and splattering during high-speed production, providing a reliable guarantee for the stable operation of thermal paper coating production lines. It also meets market demands for diverse thermal paper varieties and high-quality standards, playing a crucial role in advancing high-speed coating finishing equipment for thermal paper.
