Description

Technical Field

[0001] The invention relates to the technical field of solid wood board processing, in particular to a device for preventing deformation of solid wood board after processing and forming. Background Art

[0002] After the solid wood board is formed, it needs to be treated to prevent deformation, so as to avoid bending, deformation, cracking and other problems during the later use of the solid wood board. The moisture content in the solid wood board is the main factor controlling whether the solid wood board will deform. Therefore, when performing anti-deformation treatment on the solid wood board, the moisture content in the solid wood board needs to be reduced.

[0003] The traditional anti-deformation treatment method for solid wood boards is to stack the solid wood boards in a dedicated drying room, and by controlling the humidity, temperature and flow rate of the air inside the drying room, the moisture content of the solid wood boards reaches the specified standard.

[0004] Solid wood boards are stacked in the drying room. The gaps between the stacked solid wood boards are small. When the gas inside the drying room circulates, it is difficult for it to enter the stacked solid wood boards. The gas fluidity inside the stacked solid wood boards is poor, resulting in low efficiency of the solid wood board drying process, uneven control of the moisture content in the solid wood boards, and certain bending deformation of the solid wood boards after treatment. The anti-bending treatment effect of the solid wood boards is not good. Summary of the Invention

[0005] In order to solve the problems of low efficiency of solid wood board drying in traditional drying rooms, uneven control of moisture content in solid wood board, certain bending deformation of solid wood board after treatment, and poor anti-bending treatment effect of solid wood board, the present invention is achieved through the following technical solutions: A device for anti-deformation treatment of solid wood board after processing and forming, comprising a processing box and several groups of support platforms and a group of pressing plates, wherein square bars are slidably mounted on the upper surface of the support platforms, and a sealed cavity is provided below the square bars, and the cavity is connected to a hydraulic system or a pneumatic system for hydraulic or pneumatic expansion and contraction control of the square bars. When the solid wood board is subjected to anti-deformation treatment, the solid wood board is placed on the upper surface of the square bars, and several groups of support platforms are distributed vertically inside the processing box, and the pressing plate is located above the uppermost support platform, and the lowermost support platform is fixedly installed inside the processing box, and the remaining support platforms and pressing plates are slidably mounted inside the processing box. When the square bars are retracted into the inside of the support platforms, the support platforms or pressing plates are moved downward to press the solid wood board tightly between the two support platforms or between the support platforms and the pressing plates.

[0006] The upper surface of the lowest support platform and the lower surface of the pressure plate are both provided with multiple sets of air supply ports and return air ports, and the upper and lower surfaces of the remaining support platforms are both provided with multiple sets of air supply ports and return air ports;

[0007] The solid wood boards are divided into multiple drying areas by using multiple groups of air delivery ports and return air outlets. The heated air is output through the air delivery ports and enters the return air outlets in the same group after flowing through the surface of the solid wood boards, so as to dry the solid wood boards in the divided drying areas.

[0008] Furthermore, the upper side of the interior of the lowest support platform and the lower side of the interior of the pressure plate are fixedly installed with guide plates, and the upper and lower sides of the interiors of the remaining support platforms are fixedly installed with guide plates;

[0010] Several groups of air inlet ducts, return ducts and return channels are fixedly installed inside the support platform. The air inlet duct is internally installed with a fan. One end of the air inlet duct is connected to the air delivery port, and the other end can be connected to the air inlet channel. When the air inlet duct is connected to the air inlet channel, the hot air inside the air inlet channel enters the air inlet duct and is output from the air delivery port. The pipe body of the air inlet duct near the air delivery port is a V-shaped pipe, and the output pipe of the V-shaped pipe is inclined in the direction of the return air port, so as to guide the hot air to the surface of the solid wood board;

[0011] One end of the return pipe is connected to the return channel, and the other end is connected to the outlet channel through the air guide port. The end of the return channel away from the return pipe is connected to the return air port. The hot air output from the air outlet flows through the surface of the solid wood board, enters the return channel through the return air port, and then enters the outlet channel through the return pipe, and is discharged from the processing box through the outlet channel.

[0012] Furthermore, a plurality of strip-shaped ventilation slots are provided on the surface of the air inlet channel and the air outlet channel away from the inner cavity of the support platform, and baffles are installed inside the air inlet channel and the air outlet channel, and the baffles control the opening and closing of the ventilation slots and the air inlet channel and the air outlet channel. When the square bars extend out of the surface of the support platform, the ventilation slots and the air inlet channel and the air outlet channel are in a closed state. When the solid wood board is pressed by using the support platform or the pressing plate, the ventilation slots and the air inlet channel and the air outlet channel are in an open state. In this state, the air flowing through the air inlet channel and the air outlet channel can continue to dry the surface of the solid wood board.

[0013] The baffle is rotatably installed in the inner wall of the air inlet channel or the air outlet channel, and a transmission gear is fixedly installed on the adapter end of the baffle. A rack is slidably installed in the inner wall of the air inlet channel and the air outlet channel, and the rack is engaged with the transmission gear. The rack is controlled to move by an adjustment cylinder installed on the inner wall of the air inlet channel or the air outlet channel.

[0014] A plurality of drainage pipes are fixedly installed inside the support platform, and the drainage pipes are used to control the direction of hot air transportation inside the air inlet channel. One end of the drainage pipe is connected to the air inlet channel, and the other end is connected to the return pipe. The connection end of the drainage pipe and the air inlet channel passes through the interior of the air inlet pipe, and the drainage pipe is located on the pipe surface of the inner section of the air inlet pipe and has an air outlet;

[0015] When the air inlet channel is connected to the air inlet pipe through the air outlet, the air inlet channel is not connected to the return pipe; when the air inlet channel is connected to the return pipe through the drainage pipe, the air inlet channel is not connected to the air inlet pipe.

[0016] Furthermore, a second fan is installed inside the return pipe, and the second fan is located between the connection port and the air guide port of the drainage pipe and the return pipe.

[0017] Furthermore, a retaining ring is slidably installed inside the drainage tube, and the retaining ring can be sealed with the air outlet when it moves. When the retaining ring is sealed with the air outlet, the air inlet channel is connected with the return tube through the drainage tube. A blocking block is fixedly installed inside the drainage tube, and the blocking block is located on the side of the air outlet away from the air inlet channel. The retaining ring can be sealed with the blocking block when it moves. When the retaining ring is sealed with the blocking block, the air inlet channel is connected with the air inlet tube through the drainage tube. A hydraulic telescopic rod or a pneumatic telescopic rod is installed inside the drainage tube, and the movement of the retaining ring is controlled by the hydraulic telescopic rod or the pneumatic telescopic rod.

[0018] Furthermore, a threaded rod is rotatably installed inside the processing box, and the rotation of the threaded rod is controlled by a motor device. The surface of the threaded rod is covered with a plurality of connecting blocks, and the connecting blocks are fixedly installed with the side surfaces of the slidable support platform and the pressure plate;

[0019] A threaded ring is provided inside the connection block, and the threaded ring is composed of at least two half-ring structures, and the half-ring structures of the threaded ring are slidably installed inside the connection block;

[0020] When the half-ring structure of the threaded ring engages with the threaded rod, the threaded rod rotates to drive the support platform or pressure plate to move upward or downward. When the half-ring structure of the threaded ring disengages from the threaded rod, two adjacent support platforms or support platforms cooperate with the pressure plate to press the solid wood board.

[0021] Furthermore, a connecting block is also fixedly installed on the side surface of the lowermost support platform, and a limiting rod is slidably installed on the lower surface of the connecting block of the slidable support platform and the side surface of the pressing plate, and a return spring is provided between the limiting rod and the connecting block. When the lower end of the limiting rod moves down to contact the next connecting block, the support platform or the pressing plate presses the solid wood board;

[0022] An inner rod is slidably mounted inside the limit rod, and the lower end of the inner rod is fixedly connected to the next connecting block. An adjusting rod is slidably mounted on one end of the limit rod located inside the connecting block, and a supporting spring is provided between the adjusting rod and the inner rod. When the inner rod slides toward the inner direction of the limit rod, it can contact the adjusting rod.

[0023] A compression spring is provided between the semi-ring structure of the threaded ring and the inner wall of the connecting block. A rotating rod is rotatably installed on the inner wall of the connecting block. The end of the rotating rod away from the connecting block is slidably installed on the outer surface of the semi-ring structure. The end of the adjusting rod away from the limiting rod is slidably connected to the rotating rod. When the rotating rod is in a horizontal state, the semi-ring structure of the threaded ring is threadedly engaged with the threaded rod.

[0024] When the inner rod slides toward the inside of the limit rod and contacts the adjusting rod to push the adjusting rod to move, the movement of the adjusting rod will push the rotating rod to rotate, and the rotating rod drives the semi-ring structure of the threaded ring to move, so that the semi-ring structure is separated from the threaded rod. At this time, when the threaded rod rotates, it will not engage with the threaded ring; when the limit rod slides in the direction away from the connecting block, the limit rod will drive the adjusting rod to move through the supporting spring, and the movement of the adjusting rod will push the rotating rod to rotate, and the rotating rod drives the semi-ring structure of the threaded ring to move, so that the semi-ring structure is separated from the threaded rod. At this time, when the threaded rod rotates, it will not engage with the threaded ring.

[0025] A method for preventing deformation of a solid wood board after processing and forming, comprising the following specific steps:

[0026] S1. Place the solid wood board on the surface of the square bar inside the processing box. At this time, there is a gap between the upper and lower surfaces of the solid wood board and the corresponding support platform or pressing plate;

[0027] S2. Heat the air to 50-70°C, and then deliver the heated air to the air inlet channel. The hot air inside the air inlet channel enters the air inlet pipe through the air outlet and is output through the air outlet. After flowing through the surface of the solid wood board, the hot air enters the return channel through the return air outlet;

[0028] S21, using air inlets and return air outlets to divide the solid wood board into multiple drying zones, and using hot air to dry each drying zone;

[0030] S4. Connect the air inlet channel and the air outlet channel to the ventilation slots, and connect the air inlet channel to the return channel and the air outlet channel through the drainage pipe. At this time, the hot air entering the air inlet channel enters the return channel through the drainage pipe, then enters the air outlet channel through the air guide port, and is output from the air outlet channel. While the hot air flows through the air inlet channel and the air outlet channel, it continues to dry the solid wood board.

[0031] S5. When the moisture content of the solid wood board is reduced to 8-13%, the anti-deformation treatment of the solid wood board is completed.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The device for preventing deformation of solid wood boards after processing and forming can divide the surface of the solid wood boards into several drying areas through the combined design of several support platforms and pressing plates inside the processing box and the combined design of the air inlet and air outlet channels inside the guide plates in the support platforms and pressing plates and the air inlet and return pipes. The hot air returning from the air supply port and the return air port can dry the surfaces of the solid wood boards in the corresponding areas.

When the moisture content of the solid wood board drops to 20%, the square bar 3 is retracted into the inside of the support platform 2, and the support platform 2 and the pressing plate 101 are moved downward until two adjacent support platforms 2 or the support platform 2 and the pressing plate 101 press the solid wood board tightly;

[0081] S4. Connect the air inlet channel 41 and the air outlet channel 42 to the ventilation slot 43, and use the drainage pipe 7 to connect the air inlet channel 41 to the return pipe 9 and the air outlet channel 42. At this time, the hot air entering the air inlet channel 41 enters the return pipe 9 through the drainage pipe 7, and then enters the air outlet channel 42 through the air guide port 92 and is output from the air outlet channel 42. When the hot air flows in the air inlet channel 41 and the air outlet channel 42, the solid wood board continues to be dried.

[0082] S5. When the moisture content of the solid wood board is reduced to 8%, the anti-deformation treatment of the solid wood board is completed.

[0083] Working principle of solid wood board anti-deformation treatment device:

[0084] refer to Figure 1-Figure 2 After the solid wood board is formed, it is placed in the processing box 1. At this time, the square bars 3 on the surface of the support platform 2 are in an extended state, and the solid wood board is placed on the surface of the square bars 3. There is a certain distance between the upper and lower surfaces of the solid wood board and the corresponding support platform 2 or the pressing plate 101. At this time, the baffle 5 inside the guide plate 4 is in a coordinated state with the ventilation slots 43 in the air inlet channel 41 and the air outlet channel 42.

[0085] refer to Figure 3-Figure 10Start the air heating equipment to transport the heated air into the air inlet channel 41, and start the fan 1 61 inside the air inlet pipe 6 and the fan 2 91 inside the return pipe 9. Under the action of the fan 1 61, the hot air inside the air inlet channel 41 enters the air inlet pipe 6 through the air outlet 71 and is output through the air delivery port 21. The hot air will flow through the surface of the solid wood board. Under the action of the fan 2 91, a negative pressure will appear at the return air port 22. When the hot air flowing through the solid wood board approaches the return air port 22, it will enter the return channel 10 through the return air port 22 and will enter the air outlet channel 42 through the return pipe 9. In this way, the air delivery port 21 and the return air port 22 can be used to divide the solid wood board into multiple drying areas, and each drying area can be dried with hot air to reduce the moisture content in the solid wood board.

[0086] refer to Figure 11-13 When the moisture content in the solid wood board drops to a set range, the cavity 31 is used to shrink the square bar 3 into the inside of the support platform 2. At this time, the threaded rod 13 is driven to rotate by the relevant motor equipment, and the threaded rod 13 engages with the threaded ring 12 inside the connecting block 11, driving the movable support platform 2 and the pressing plate 101 to move downward.

[0087] When the lowest movable support platform 2 moves downward, the inner rod 141 inside the limiting rod 14 on the lower surface of its corresponding connecting block 11 will slide toward the inner direction of the limiting rod 14 until the inner rod 141 pushes the adjustment rod 142 to move, causing the adjustment rod 142 to drive the semi-ring structure of the threaded ring 12 to move through the rotating rod 143, and the semi-ring structure of the threaded ring 12 is separated from the threaded rod 13. At this time, the lower end of the limiting rod 14 contacts the surface of the next connecting block 11, and the solid wood board below this support platform 2 is just pressed by the two support platforms 2. Similarly, several movable support platforms 2 and pressing plates 101 will cooperate with the corresponding support platforms 2 in sequence to press the solid wood board.

[0088] After the solid wood board is pressed, the adjusting cylinder 53 is started at this time, and the engagement of the rack 52 and the transmission gear 51 is used to drive the baffle 5 to rotate, so that the air inlet channel 41 and the air outlet channel 42 are connected to the ventilation slot 43. At the same time, the hydraulic telescopic rod or the starting telescopic rod is used to drive the baffle ring 8 to move, so that the baffle ring 8 is sealed with the air outlet 71. At this time, the hot air entering the air inlet channel 41 will enter the return pipe 9 through the drainage pipe 7, and under the action of the fan 2 91 in the return pipe 9, it enters the air outlet channel 42 through the air guide port 92 and is output from the air outlet channel 42. When the hot air flows in the air inlet channel 41 and the air outlet channel 42, the solid wood board will be further dried until the moisture content in the solid wood board reaches the qualified range, and the anti-deformation treatment of the solid wood board is completed in sequence.

[0089] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
