[0002] With the continuous advancement of technology, more and more materials are appearing in our lives, providing convenience for people. Among them, thermal paper is also called thermal fax paper, thermal recording paper, and thermal copy paper. Thermal paper is a kind of processed paper. When thermal paper is heated, the colorless dye reacts with the developer to produce color. Therefore, when the thermal paper is used to receive the signal on the fax machine or directly print with a thermal printer, the picture and text will be displayed. Since there are many varieties of colorless dyes, the colors of the displayed handwriting are different, including blue, purple, black, etc.

[0003] The thermal paper processing equipment used in the research and development of combustion-supporting label self-adhesive labels lacks protective devices. When unloading, the thermal paper is usually required to be handled manually, because the thermal paper will change when exposed to heat.
