Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal sheet processing, in particular to a thermal sheet flattening mechanism. Background Art
[0002] The thermal print head of a thermal printer is made of thermal elements. The thermal sheet on the printing device is mainly composed of a ceramic substrate as a carrier. Rows of densely packed elements are encapsulated on the thermal sheet. However, the thermal elements will quickly generate high temperatures when a certain current passes through them. When the medium coating encounters these elements, it will heat up in a very short time, causing the coating to react and display color, thereby achieving the printing effect.
[0003] After searching, it is found that the thermal film for printers needs to be glued during production and processing, but due to the long length of the thermal film, it will be deformed in the middle, so that during the glue dispensing process, the glue will flow due to the arch, resulting in uneven glue dispensing, which is easy to cause poor quality.
