Description

Technical Field

[0001] This application relates to the technical field of solid wood board processing, and in particular to a wood drying device for multi-layer board processing. Background Art

[0002] A multi-layer board is a three-layer or multi-layer board-shaped material formed by slicing a wood segment into veneers or planing a wooden square into thin woods, and then gluing them with an adhesive. Usually, odd-numbered layers of veneers are used, and the fiber directions of adjacent layers of veneers are glued perpendicular to each other. The multi-layer board is also called plywood and is one of the commonly used materials for furniture.

[0003] During the processing of multi-layer boards, it is necessary to dry the inside of the multi-layer boards for processing to prevent moisture from remaining inside the boards, which may cause the boards to crack after processing, affecting the overall efficiency and aesthetics of board processing.

[0004] When the wood board is dried in a drying device, since the position of the air outlet in a general drying device is fixed, the air flow direction is fixed, so that there may be problems of uneven drying or incomplete drying of the moisture in the board during the drying process of the wood board.

The two supporting frames 60 support a plurality of multi-layer boards 70 and are inserted into the gaps between the four positioning frames 80, so that a plurality of multi-layer boards 70 are located between several groups of side air supply components 30 and simultaneously above the bottom air supply component 20. The bottom air supply component 20 and the side air supply components 30 can be used to dry the multi-layer boards 70 in multiple directions and positions.

[0021] In this embodiment, a grid plate 11 is formed on the top of the drying chamber 10, and a plurality of exhaust slots penetrating the grid plate 11 are formed on the grid plate 11. During the process of drying the multi-layer boards 70, the hot air flow and water vapor can be discharged upward through the exhaust slots. A base 12 is formed at the bottom of the drying chamber 10, and an installation slot 13 for installing the bottom air supply component 20 is formed in the middle of the base 12. A cabinet door is also hinged to the front of the drying chamber 10, and after opening the cabinet door, the multi-layer boards 70 can be taken out or placed into the drying chamber 10.

The eccentric shaft 36 is formed at the outer edge of the side of the turntable 35 facing away from the fixed seat 31. Both ends of the movable arm 37 are rotatably connected to the eccentric shaft 36 and the bottom of the swing seat 38 respectively. The swing seat 38 is rotatably connected to the fixed seat 31 by the positioning shaft 39. When the turntable 35 drives the eccentric shaft 36 to rotate, the eccentric shaft 36 can drive the movable arm 37 to move, and the movable arm 37 drives the swing seat 38 to swing by the positioning shaft 39. The swing seat 38 constitutes the movable end of the side air supply assembly 30, and the side air supply duct 50 is inserted on the movable end of the side air supply assembly 30, so that the side air supply duct 50 can be arranged to swing and supply air to the side of the multi-layer board 70 to be dried in the drying chamber 10 for drying treatment.
