TECHNICAL FIELD

[0001] The utility model relates to the technical field of veneer dyeing, in particular to a heating equipment for veneer dyeing. BACKGROUND

[0002] Dyed veneer is a new type of decorative material made of natural veneer after defect treatment and coloring by high-tech processing technology, which is collectively referred to as dyed veneer. It is a beneficial supplement to natural veneer. Due to the flexibility of its color, it leaves color imagination space for designers, and adds a lot of color to the living environment. Dyed veneer first needs to select suitable veneer (some veneer cannot be done due to its nature), then to the factory for bleaching (usually about 6 hours, and the wood quality is determined by the time), the purpose is to unify the color for the next step, then after soaking in the pre-prepared pigment (dye), the basic veneer has color, then fix the color, dry, hot-press flat, cut, package. Before the veneer is immersed in the dye, the dyeing agent is usually poured into hot water and stirred, and then the veneer is put in. However, during production, the water usually needs to be heated first, and then the hot water and the dyeing agent are poured into the container for manual stirring. The process is more and the efficiency is lower. In the process of hot water delivery, a part of heat will be lost. Therefore, an equipment that can heat and stir at the same time is needed to assist the veneer dyeing operation.
