Description

Technical Field

[0001] The utility model relates to plate processing auxiliary equipment, in particular to an improvement of a wood veneer auxiliary drying device. Background Art

[0002] Wood veneer is a veneer made by peeling logs into specific sizes. Since the moisture content of logs cut down from the mountains is high, usually more than 40%, the wood veneer needs to be dried before it can be processed by gluing and hot pressing.

[0003] Traditionally, wood veneers are dried by natural airing, which is limited by natural conditions and requires a lot of manpower and is inefficient throughout the drying process.

[0004] At present, in order to improve efficiency, many board companies adopt various veneer drying methods such as static drying room, batch trolley drying room, flip drying line, drum drying line, etc. These drying processes all use the heat exchanger in the drying room to transfer heat to the air, and then the air dries the veneer; such drying process has the disadvantages of large drying equipment footprint, expensive equipment, low output, high energy consumption, and high drying cost. Utility Model Content

[0005] The purpose of the utility model is to provide a novel wood veneer drum drying machine in view of the defects and shortcomings of the prior art. The utility model allows a heat source to pass into the interior of the roller, and the roller directly clamps and contacts the wood veneer. The heat on the roller is directly conducted and acts on the wood veneer, thereby achieving the effect of rapid heating and rapid drying of the veneer, reducing intermediate heat loss, improving heat conduction efficiency, reducing equipment footprint, and reducing energy consumption and improving production efficiency.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises an equipment support 1, a driving motor 2, and multiple groups of heating rollers 3; the multiple groups of heating rollers 3 are arranged in parallel on the equipment support 1, and each group of heating rollers 3 comprises two single rollers 31, the two single rollers 31 are arranged up and down, and a gap 32 is arranged between the two single rollers 31; double-row sprockets 311 are arranged at both ends of the two single rollers 31, the double-row sprockets 311 of the upper and lower single rollers 31 are meshed with each other, and each lower row of double-row sprockets 311 is connected to the driving end of the driving motor 2 through a transmission chain 4; the two ends of the single roller 31 are respectively a heat source inlet 312 and a heat source outlet 313, each heat source inlet 312 is connected to a total heat source inlet pipe 5, and each heat source outlet 313 is connected to a total heat source outlet pipe 6.

[0007] The total heat source inlet pipe 5 is connected to an external heat source, which may be heat transfer oil, hot steam or other heat media; the total heat source outlet 6 is used as a heat source loop to return to the external heat source. It transmits heat media to each single roller 31 through the external heat source, bringing heat to each single roller 31.

[0008] The single roller 31 includes a seamless steel pipe 314, a T-shaped plug 315, a skeleton oil seal 316, a hollow support shaft 317, and a heat source pipe joint 318. The T-shaped plug 315 is arranged at both ends of the seamless steel pipe 314, the hollow support shaft 317 is inserted in the T-shaped plug 315, and the hollow support shaft 317 and the T-shaped plug 315 are supported by two bearings 319. A skeleton oil seal 316 is arranged at the joint between the hollow support shaft 317 and the T-shaped plug 315, a double-row sprocket 311 is sleeved on the outer side of the T-shaped plug 315, and the heat source pipe joint 318 is inserted at the outer joint of the T-shaped plug 315.

[0009] A box 7 is provided outside the equipment support 1, and the wood inlet end and the driving motor 2 in the plurality of heating rollers 3 extend out and are arranged outside the box 7. By providing the box 7, the heat emitted by the internal single roller 31 can be enclosed and preserved, so that the wood veneer can have a better heating effect inside.

[0010] Several fans 71 are arranged in the box 7. The fans 7 can accelerate the flow of air in the box 7, thereby accelerating the volatilization of water in the wood veneer and ensuring the drying effect.

[0011] The working principle of the utility model is as follows: when in use, the staff turns on the external heat source and introduces the heat source into the multiple groups of heating rollers 3, and starts the driving motor 2, thereby driving each group of heating rollers 3 to rotate, and the upper and lower single rollers 31 of the same group of heating rollers 3 rotate in opposite directions; the staff puts the peeled wood veneer through the gap 32 set between the two single rollers 31 at the entrance, and the wood veneer slowly passes through the multiple groups of heating rollers 3 under the rotation of the upper and lower single rollers 31. Since the heating rollers 3 are in a high temperature state, in this state, the wood veneer passes through the multiple groups of heating rollers 3, and the effect of dehumidification and drying is achieved. It can adjust the number of groups of heating rollers 3 according to the moisture level of the wood veneer, and can also achieve the speed of dehumidification and drying by adjusting the rotation speed.

[0012] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: it passes the heat source into the inside of the roller, the roller directly clamps and contacts the wood veneer, and the heat on the roller is directly conducted and acts on the wood veneer, thereby achieving the effect of rapid heating and rapid drying of the veneer, reducing intermediate heat loss, improving heat conduction efficiency, reducing equipment footprint, and reducing energy consumption and improving production efficiency.
