[0002] A veneer drying device is a specialized piece of equipment used to dry veneer, reducing its moisture content to a suitable level to meet the requirements of subsequent processing and use.

[0003] Currently, the conveyor belts of wood veneer dryers are arranged horizontally. The wood veneer is fed onto the conveyor belt, dried in the drying chamber, and cooled in the cooling chamber before being discharged. In order to ensure the drying quality of the wood veneer, it needs to stay in the drying chamber for a sufficient amount of time. One solution is to increase the span of the drying chamber, which results in a larger space occupied by the drying equipment. Another solution is to reduce the speed of the conveyor belt, which will reduce the drying efficiency of the wood veneer. Utility Model Content

[0031] The chassis 1 contains a drying chamber 2 and a cooling chamber 3.

[0032] A vertical circulating elevator 4 is installed inside the drying chamber 2, and each basket 5 of the vertical circulating elevator 4 is equipped with a transfer mechanism 6.

[0033] Two sets of roller conveyors 7 are connected to opposite sides of the vertical circulating elevator 4, with one set of roller conveyors 7 located inside the cooling chamber 3;

[0034] The dryer 8 is fixedly installed on the housing 1 and is connected to the interior of the drying chamber 2;

[0035] The air cooler 9 is fixedly installed on the casing 1, and the air cooler 9 is connected to the interior of the cooling chamber 3;

[0036] The transposition mechanism 6 includes a lead screw 61, a servo motor 62, and a support plate 63. The lead screw 61 is hinged to the hanging basket 5, the servo motor 62 is fixedly connected to the hanging basket 5, and the servo motor 62 is connected to and drives the lead screw 61. The support plate 63 is slidably connected to the hanging basket 5, and the support plate 63 is screwed to the lead screw 61. The rotation of the servo motor 62 drives the lead screw 61 to rotate, and the screw connection between the lead screw 61 and the support plate 63 drives the support plate 63 to slide horizontally on the hanging basket 5. This allows it to receive wood veneer conveyed by one set of roller conveyors 7, or to send the dried wood veneer to another set of roller conveyors 7, facilitating the conveying operation of wood veneer.

[0037] The suspended basket 5 is provided with two sliding rods 10, and the support plate 63 is slidably connected to the sliding rods 10 to ensure the stability of the sliding of the support plate 63;

[0038] The roller conveyor 7 includes a fixed frame 71, multiple support rollers 72, a drive shaft 73, and a drive motor 74. The multiple support rollers 72 are arranged in a straight line and hinged to the fixed frame 71. The drive shaft 73 is hinged to the fixed frame 71, and the axis of the drive shaft 73 is perpendicular to the axis of the support rollers 72. The drive motor 74 is fixedly connected to the fixed frame 71. The drive motor 74 is connected to and drives the drive shaft 73 through a chain and a sprocket. The multiple support rollers 72 are connected to the drive shaft 73 through multiple belts. When the drive motor 74 rotates, the drive shaft 73 rotates under the transmission action of the sprocket and the chain. The drive shaft 73 drives the multiple support rollers 72 to rotate synchronously through the multiple belts, thereby smoothly conveying the wood veneer.

[0039] Working principle: First, a structure similar to a safe vertical circulating parking garage disclosed in Chinese patent (CN201820792259.8) is selected as the vertical circulating lift 4. Second, the wood veneer is placed on a set of roller conveyors 7, and the drive motor 74 rotates. Under the transmission action of sprockets and chains, the drive shaft 73 rotates. The drive shaft 73 drives multiple support rollers 72 to rotate synchronously through multiple belts, thereby sending the wood veneer to a certain basket 5. The servo motor 62 rotates, driving the lead screw 61 to rotate. The screw connection between the lead screw 61 and the support plate 63 drives the support plate 63 to slide horizontally on the basket 5, thereby adjusting the position of the wood veneer on the basket 5. As the vertical circulating lift 4 operates, the wood veneer is continuously fed up. The wood veneer is placed on multiple hanging baskets 5. Then, the dryer 8 injects hot air into the drying chamber 2 to dry the wood veneer on the hanging baskets 5. The wood veneer on the hanging baskets 5 can stay in the drying chamber 2 for a sufficient amount of time. Finally, the servo motor 62 rotates, driving the lead screw 61 to rotate. The screw connection between the lead screw 61 and the support plate 63 drives the support plate 63 to slide horizontally on the hanging baskets 5, moving the wood veneer on the hanging baskets 5 to the roller conveyor 7 located in the cooling chamber 3. The drive motor 74 rotates, and the drive shaft 73 rotates under the transmission action of the sprocket and chain. The drive shaft 73 drives multiple support rollers 72 to rotate synchronously through multiple belts, thereby realizing the conveying of wood veneer. The cold air fan 9 injects cold air into the cooling chamber 3 to cool the wood veneer, and then the cooled wood veneer can be unloaded.
