Description
TECHNICAL FIELD

[0002] Wood pallets are pallets made of natural wood, which are the most widely used type of pallets today. Due to their simple structure, they are widely used for transporting unit goods and small quantities of goods. Wood pallets have a wide range of applications in the logistics, warehousing and other industries, and their quality and performance are crucial to the safe storage and transportation of goods. In the production process of wood pallets, drying is a key step. Many drying equipment uses a single heating method and a simple ventilation structure. For example, some drying boxes only have a heating source at the bottom, and the heat gradually dissipates during upward transmission, resulting in a significant temperature gradient in the vertical direction of the wood pallet. The wood near the bottom is heated more, while the wood at the top is not heated enough. In addition, due to uneven ventilation, there are also local temperature differences in the horizontal direction. This uneven drying can cause uneven stress in the wood, which can easily cause wood deformation, warping, cracking and other problems. In severe cases, it may cause the wood pallet to be unable to function properly, increasing the scrap rate and production cost. CONTENT OF THE UTILITY MODEL
