[0023] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Combined with reference Figure 1-Figure 4 The utility model provides a platen-type wood drying machine, including a drying box 1, a pair of supporting ear plates 2 are fixedly connected to the bottom of the drying box 1, and the supporting ear plates 2 can be used to suspend the drying box 1 to avoid moisture. A sealing door 3 is rotatably connected to the drying box 1 through a hinge, and the sealing door 3 can ensure the dryness and sealing of the inside of the drying box 1. A pair of lower support plates 4 are arranged at the inner bottom of the drying box 1, and a plate support plate 41 is fixedly connected to each lower support plate 4, and the plate support plate 41 can be used to support wood. A pair of lower support plates 4 are provided with a spacing adjustment structure 5, and each lower support plate 4 A pair of columns 6 are fixedly connected on the top, and a plurality of pressure plate gaskets 8 are movably connected on the pair of columns 6. The pressure plate gaskets 8 are arranged to overlap with the wood. The pressure plate gaskets 8 can be padded between adjacent woods, so that gaps can be provided for adjacent woods. The gaps are convenient for air circulation, which can improve the efficiency and uniformity of wood drying. A sliding support assembly 7 is arranged on the inner top of the drying box 1. The sliding support assembly 7 is connected to the columns 6. A gasket storage structure 9 for storing the pressure plate gaskets 8 is arranged on the sliding support assembly 7. The drying box 1 is provided with a drying circulation system.

[0025] The spacing adjustment structure 5 includes a pair of slide rails 51 fixedly connected to the bottom of the drying box 1, a bidirectional screw rod 52 threadedly connected to a pair of lower support plates 4, and a rotating motor 53 fixedly connected to the side of the drying box 1. The pair of lower support plates 4 are slidably connected to the pair of slide rails 51, and the output end of the rotating motor 53 is fixedly connected to one end of the bidirectional screw rod 52.

[0026] Specifically, by rotating the motor 53 to drive the bidirectional lead screw 52 to rotate forward and backward, and under the guidance of the first slide rail 51 for the lower support plate 4 to slide, a pair of lower support plates 4 can move closer to or away from each other, so as to adjust the distance between a pair of plate pallets 41 for supporting the wood, to meet the dimensional requirements of different batches of wood specifications.

[0027] The pressing plate gasket 8 is arranged in a "C" shape. The protruding settings at both ends of the pressing plate gasket 8 can reduce the contact area with the wood, so as to maximize and reserve a ventilation space. In this application, the thickness of the pressing plate gasket 8 is set at 1.5 - 2.0 mm. Under the condition of effectively reserving the space between the woods, the occupied thickness of the pressing plate gasket 8 can be maximally reduced to meet the requirements of the wood drying amount.

[0028] The sliding support assembly 7 includes a pair of second slide rails 71 fixedly connected to the inner top of the drying box 1 and a pair of upper support plates 72 slidably connected to the pair of second slide rails 71. The upper support plates 72 and the lower support plates 4 are on the same horizontal plane. One end of the column 6 facing away from the lower support plate 4 is fixedly connected to the upper support plate 72. When the lower support plate 4 moves, it can drive the upper support plate 72 to slide on the second slide rail 71 through the column 6. In this way, both ends of the column 6 are supported by the upper support plate 72 and the lower support plate 4, so as to stabilize the standing position of the column 6.

[0029] The number of the gasket storage structures 9 is a pair. The gasket storage structure 9 includes a fixed block 91 fixedly connected to one side of the upper support plate 72, a rotating rod 92 rotatably connected to the fixed block 91, and a hanging plate 93 fixedly connected to the bottom end of the rotating rod 92. The hanging plate 93 is used to support the pressing plate gasket 8.

[0030] Specifically, when it is necessary to dry the wood or not, several pressing plate gaskets 8 on the column 6 can be centrally collected and pushed upward at this time. Then the hanging plate 93 can be rotated to let the pressing plate gasket 8 pass over the hanging plate 93, and then the hanging plate 93 is rotated back to the bottom of the pressing plate gasket 8, so that the pressing plate gasket 8 can be stored. Subsequently, by peeling off the pressing plate gaskets 8 one by one and sliding them down on the column 6, the requirements for padding during wood drying can be met.

[0031] The drying circulation system includes a pair of air heaters 11 fixedly penetrating through one side of the drying box 1, a pair of blowers 10 fixedly connected to the inner wall of the other side of the drying box 1, an exhaust fan 12 fixedly penetrating through the top of the drying box 1, and a circulation air duct 13 fixedly communicated with the discharge port of the exhaust fan 12. In this setting, the exhaust fan 12 is located above the blower 10.

[0032] A supply air duct 14 fixedly communicated with the air inlet of the air heater 11 is fixedly connected to the circulation air duct 13. The hot air source recovered by the circulation air duct 13 can be blown to the air inlet of the air heater 11, so as to facilitate and quickly preheat the air, thereby improving the stability of the drying heat source.

[0033] Specifically, when the wood pressing plates are stacked, the sealing door 3 can be closed, and the air heater 11, the hair dryer 10 and the exhaust fan 12 can be started at this time. A pair of hair dryers 10 are arranged on the right side of the wood, so that the setting of the hair dryer 10 blowing upward can speed up the flow of air at the wood drying position. The air heater 11 is used to heat the air, and the hair dryer 10 can introduce the heated air into the drying box 1 and circulate it around the wood and in the gaps, so as to ensure that the wood is dried comprehensively and evenly. At the same time, due to the exhaust setting of the exhaust fan 12, the hot air blown by the hair dryer 10 can be drawn out, and the hot air can be sent to the air inlet area of ​​the air heater 11 through the circulating air duct 13. By advancing the waste heat air, the heating stability of the air heater 11 can be improved.
