[0002] Leather tanning refers to the production of leather that is not easy to rot, flexible, breathable, etc. by processing animal raw hides through physical and chemical methods such as depilation and tanning, and then through coating and finishing. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster and feels comfortable. Retanning occupies a very important position in the modern leather industry and is the most critical process in leather production. The quality of retanning determines the quality of leather retanning.

[0003] In the process of using the existing constant temperature heating device for leather retanning, the leather is laid flat, and there is a problem of local heating, which leads to uneven heating of the leather. If the same place of the leather is heated for a long time, it is easy to cause certain damage to the leather, affecting the effect of leather retanning. Therefore, we propose a constant temperature heating device for leather retanning. Utility Model Content
