[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figure 1-7 This utility model provides a technical solution: a multi-layer roller cylindrical wood veneer drying device, comprising:

[0043] A fixed frame 1 is provided with a hot air box 2;

[0044] A multi-layer conveying mechanism 3 is arranged vertically and installed on the fixed frame 1;

[0045] Drying mechanism 4 is installed on the hot air box 2 and extends to the multi-layer conveying mechanism 3;

[0046] Cooling mechanism 5 is mounted on the fixed frame 1 and is located on one side of the hot air box 2;

[0047] The conveying mechanism 3 includes a driver 31 and multiple double-layer rollers 32. The multiple double-layer rollers 32 are arranged horizontally and installed on the fixed frame 1. The driver 31 is installed on the fixed frame 1 and is connected to and drives the multiple double-layer rollers 32. The driver 31 drives the multiple double-layer rollers 32 to roll, thereby synchronously conveying the wood veneer.

[0048] The double-layer roller 32 includes two support frames 321 and two drive rollers 322. The two support frames 321 are fixedly connected to the fixed frame 1. Limit bearings 6 are sleeved at opposite ends of the drive rollers 322, and the two limit bearings 6 are respectively inserted into the two fixed frames 1. Driven gears 7 and driven sprockets 8 are respectively connected to opposite ends of the lower drive roller 322. A driven gear 7 is provided at one end of the upper drive roller 322. The two driven gears 7 mesh with each other. A drive sprocket 9 is provided on the driver 31, and the drive sprocket 9... Chain 10 connects multiple driven sprockets 8. The drive 31 rotates, driving the drive sprocket 9 to rotate. Under the transmission action of chain 10, multiple driven sprockets 8 rotate synchronously, thereby driving the lower drive roller 322 on the double-layer roller 32 to rotate. Due to the meshing action between the driven gears 7, the upper drive roller 322 rotates in the opposite direction to the lower drive roller 322, thereby realizing that the two drive rollers 322 clamp the veneer to transport the veneer. The modular structure design makes the drive roller 322 easier to expand, install, repair and replace compared to the traditional drive roller 322 welded to the fixed frame 1.

[0049] The surface of the limiting bearing 6 is provided with a limiting groove 11, and the support frame 321 is provided with a U-shaped groove 12. The limiting bearing 6 is inserted into the U-shaped groove 12, and the inner wall of the U-shaped groove 12 is inserted into the limiting groove 11, which facilitates the snap-fit ​​installation between the drive roller 322 and the support frame 321.

[0050] Two limiting pins 13 are inserted into the support frame 321. The two limiting pins 13 are located above the driven sprocket 8 and the limiting bearing 6. The limiting plate 14 is inserted into the two limiting pins 13 to limit the position of the drive roller 322 on the support frame 321 and prevent the drive roller 322 from falling off.

[0051] The drying mechanism 4 includes a hot air blower 41 and multiple air ducts 42. The hot air blower 41 is fixedly connected to the hot air box 2. The multiple air ducts 42 are connected to the air outlet of the hot air blower 41 through a first transition box 15, and the multiple air ducts 42 extend to the drive roller 322. The hot air generated by the hot air blower 41 is sent into the multiple air ducts 42 after passing through the first transition box 15. The multiple air ducts 42 accurately deliver the hot air to the wood veneer conveyed by the drive roller 322, so as to achieve fast and accurate drying.

[0052] The cooling mechanism 5 includes a cooler 51 and multiple air ducts 52. The cooler 51 is fixedly connected to the fixed frame 1. The multiple air ducts 52 are connected to the air outlet of the cooler 51 through a second transition box 16, and the multiple air ducts 52 extend to the drive roller 322. The cold air generated by the cooler 51 is sent into the multiple air ducts 52 after passing through the second transition box 16. The multiple air ducts 52 accurately deliver the cold air to the wood veneer conveyed by the drive roller 322, so as to achieve rapid and accurate cooling.

[0053] Both the first transition box 15 and the second transition box 16 are provided with multiple expansion ports 17. The air duct 52 and the air duct 42 are inserted into the expansion ports 17. The number of air ducts 52 or air ducts 42 can be increased or decreased according to the specific usage, which facilitates the assembly installation of air ducts 52 and air ducts 42. Plugs can be screwed onto the expansion ports 17 where air ducts 52 or air ducts 42 are not installed.

[0054] Both the air duct 42 and the air pipe 52 are provided with multiple air outlets 18. During operation, hot or cold air blown out from the air outlets 18 is directed at the wood veneer conveyed between the drive rollers 322 to dry or cool it evenly, resulting in good performance.

[0055] The drive roller 322 located inside the hot air box 2 is an electromagnetic heating roller, which allows the wood veneer to be heated while being conveyed on the drive roller 322, thus accelerating the drying of the wood veneer and improving the drying efficiency.

[0056] Working principle: First, the veneer is fed into the middle of the double-layer roller 32. The drive 31 rotates, driving the drive sprocket 9 to rotate. Under the transmission of the chain 10, multiple driven sprockets 8 rotate synchronously, thereby driving the lower drive roller 322 on the double-layer roller 32 to rotate. Due to the meshing action between the driven gears 7, the upper drive roller 322 rotates in the opposite direction to the lower drive roller 322, thus achieving the two drive rollers 322 clamping the veneer for conveying the veneer. The drive roller 322 located in the hot air box 2 is an electromagnetic heating roller to heat the veneer. Next, the hot air generated by the hot air blower 41 passes through the first transition box 1. After passing through the transition box 5, the hot air is sent into multiple air ducts 42. The multiple air ducts 42 precisely deliver the hot air to the wood veneer conveyed by the drive roller 322, achieving rapid and precise drying. After the wood veneer exits the hot air box 2, the cold air generated by the cold air blower 51 is sent into multiple air ducts 52 after passing through the second transition box 16. The multiple air ducts 52 precisely deliver the cold air to the wood veneer conveyed by the drive roller 322, achieving rapid and precise cooling. Finally, if it is necessary to inspect and maintain the drive roller 322, simply remove the corresponding limit plate 14 and limit pin 13, and take the drive roller 322 and the corresponding limit bearing 6 out of the support frame 321.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
