Description

Technical Field

[0001] The invention relates to the technical field of particleboard processing, in particular to a particleboard multi-channel drying device. Background Art

[0002] As a widely used composite board, particleboard is widely used in furniture manufacturing, building decoration and home furnishing materials due to its advantages such as low cost, easy processing and uniform density. In its production process, sufficient drying treatment is one of the essential key steps, not only to ensure the quality of the finished product, but also to ensure the structural stability of the particleboard in long-term use. Particleboard that has not been fully dried often contains a high moisture content, which will cause a series of quality problems in the finished product during use, such as cracking, warping, deformation, etc., seriously affecting the physical properties and appearance of the board. Especially in a high humidity or dry environment, the moisture change inside the board may cause its size to change, thereby affecting its fixation and service life in furniture or construction. Therefore, reasonable drying treatment in the production process not only helps to improve the strength and stability of the particleboard, but also effectively reduces the deformation rate during subsequent processing and use.

[0003] In practice, during the drying process, as the moisture content of the particleboard gradually decreases and shrinks, the common clamping device often finds it difficult to stably fix the board, causing the particleboard to shake during the drying process. In addition, the traditional clamping device is prone to leave indentations on the surface of the particleboard, affecting the appearance quality of the finished product. In practice, particleboard drying usually adopts single-channel hot air drying or natural air drying, but there are significant deficiencies in meeting large-scale production needs. The single-channel drying method is prone to uneven drying, especially the different evaporation rates of the moisture in the inner and outer layers of the particleboard, which can easily cause quality problems such as cracking or warping.
