Description

Technical Field

[0001] The invention belongs to the technical field of wood board processing equipment, and specifically refers to a wood board drying and airing device. Background Art

[0002] When the moisture content in the wood board is in the range of 20%-50%, mold is very likely to form, causing the wood board to become moldy, decayed, and worm-eaten. Drying the moisture content of the wood board to below 20% can destroy the conditions for mold growth, enhance the wood board's ability to resist mold, decay, and worms, and maintain the original characteristics and service life of the wood board. Therefore, after the raw materials are cut into boards, they need to be deeply dried for a long time. After deep drying, during storage, the surface of the wood board will absorb moisture from the air. Before the wood board is processed into furniture for the second time, the moisture on the surface of the wood board needs to be dried to improve the quality of subsequent gluing and laminating of the wood board. After drying, the board needs to be air-dried to cool the board to avoid high temperature affecting the solidification of the paint in the subsequent spraying process.

[0003] At present, during the continuous and rapid drying process of the wooden boards, the wooden boards are not clamped by any clamps. During the drying process, the moisture in the wooden boards gradually evaporates, resulting in a decrease in the adsorption force between the wooden board fibers, thereby causing the wooden boards to shrink. The shrinkage of the wooden boards is not uniform. Due to the uneven shrinkage of the wooden boards in different directions and the shrinkage of the central part of the wooden boards being restricted by the surface layer of the wooden boards, the wooden boards are prone to warping and deformation, resulting in the wooden boards being unable to meet subsequent processing requirements and an increased scrap rate. Summary of the invention

The air inlet end of the fan is connected to the cold air hood through an air duct, so that the cold air hood can draw air in the clamping gap through the air holes.

[0007] Furthermore, a plurality of lifting components are provided between the two driving brackets, and the two driving brackets are connected via the lifting components, so that the height of the clamping gap between the two plate conveyor belts can be adjusted.

[0008] Furthermore, the driving bracket includes a mounting frame and two supporting rollers, the two supporting rollers are respectively connected to the two ends of the mounting frame, the plate conveyor belt is wound around the two supporting rollers, one end of the mounting frame is provided with a driving component, the output end of the driving component is connected to the supporting roller at one end, and the driving component drives the supporting roller to rotate, so that the supporting roller can pull the plate conveyor belt to operate.

[0009] Furthermore, a connecting frame is provided on the mounting frame, and the hot air hood and the cold air hood are both installed on the connecting frame.

[0010] Furthermore, the plate conveyor belt is composed of a plurality of mutually hinged chain plates, and a shaft seat and a support lug are respectively provided on both sides of the chain plate, and the shaft seat and the support lug of two adjacent chain plates are hinged through a connecting shaft to form a joint; The support roller is provided with a groove corresponding to the joint, and when the support roller pulls the plate conveyor belt to operate, the joint engages with the groove.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0023] like Figure 1 and Figure 2 As shown, the present invention proposes a wooden board drying and airing device, comprising two plate conveyor belts 1 and two driving brackets, the two plate conveyor belts 1 are arranged up and down, so that a clamping gap 103 is formed between the two plate conveyor belts 1, and the height of the clamping gap 103 is adapted to the thickness of the wooden board, and the wooden board can be clamped by the two plate conveyor belts 1 when in the clamping gap 103; the two plate conveyor belts 1 are respectively wound around two driving brackets, and the plate conveyor belts 1 are driven to operate by the driving brackets, and the conveying directions of the two plate conveyor belts 1 in the clamping gap 103 are consistent, so that the wooden board can be clamped by the two plate conveyor belts 1 when in the clamping gap 103, and the two plate conveyor belts 1 convey the wooden board from one end of the clamping gap 103 to the other end.

[0024] Combination Figure 3 and Figure 4As shown, a hot air hood 6 is provided on both the upper and lower sides of the clamping gap 103 near one end of the incoming material direction. The hot air hood 6 is located on the inner side of the plate conveyor belt 1. The hot air hood 6 is a rectangular shell with an opening on one side, and the opening of the hot air hood 6 faces the clamping gap 103. An array of air holes 101 are provided on the plate conveyor belt 1.

[0025] A fan 8 is provided on the inner side of the two plate conveyor belts 1. The output ends of the two fans 8 are connected to a heater 9 capable of heating air. The air outlet end of the heater 9 is connected to the hot air hood 6 through an air supply pipe 91. The fan 8 supplies air into the heater 9. After being heated by the heater 9, the air is transported to the hot air hood 6 through the air supply pipe 91. Since the opening of the hot air hood 6 faces the clamping gap 103 and the plate conveyor belt 1 is provided with an air hole 101, the hot air in the hot air hood 6 can be transported to the clamping gap 103 through the air hole 101, so that the wooden board in the clamping gap 103 is dried with hot air.

[0026] Furthermore, a cold air hood 7 is provided on the upper and lower sides of the clamping gap 103 near one end of the feeding direction. The cold air hood 7 is arranged on the inner side of the plate conveyor belt 1. The cold air hood 7 is a rectangular shell with an opening on one side, and the opening of the cold air hood 7 faces the clamping gap 103. The air inlet end of the fan 8 is connected to the cold air hood 7 through the air duct 81. When the output end of the fan 8 supplies air to the heater 9, the input end of the fan 8 draws air from the cold air hood 7 through the air duct 81, and a negative pressure is formed in the cold air hood 7, so that the air in the clamping gap 103 flows into the cold air hood 7 through the air hole 101, and the cold air in the external environment is replenished into the clamping gap 103.

[0027] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the hot air hood 6 and the cold air hood 7 are attached to the inner side of the plate conveyor belt 1 on both sides of the clamping gap 103, and a plurality of support rods 61 are fixed to the open ends of the hot air hood 6 and the cold air hood 7, which can support the plate conveyor belt 1 and maintain the plate conveyor belt 1 on both sides of the clamping gap 103 in a straight state, so that the plate conveyor belt 1 can apply pressure to the wooden board in the clamping gap 103.

[0028] In this way, when the wooden board in the clamping gap 103 is transported and moved to the hot air hood 6 area, the hot air in the hot air hood 6 can be blown onto the wooden board through the air holes 101 to dry the wooden board. During the drying process, the wooden board is clamped by the plate conveyor belts 1 arranged above and below, which can avoid bending of the wooden board due to different shrinkage rates.

[0029] When the wooden board in the clamping gap 103 is dried in the hot air hood 6 area and then conveyed to the cold air hood 7 area, the negative pressure inside the cold air hood 7 allows the cold air in the external environment to be replenished into the clamping gap 103, thereby playing a role in cooling the wooden board. While cooling, the wooden board is clamped by the plate conveyor belt 1 arranged above and below, which can avoid bending of the board due to different shrinkage rates.

[0030] After the cold air in the external environment completes heat exchange with the wooden board, the cold air is heated, and then introduced into the heater 9 by the fan 8 for heating and then transported to the hot air hood 6. The waste heat of the wooden board is used to preheat the air introduced by the fan 8, thereby increasing the temperature of the air introduced by the fan 8 and reducing the energy consumption of the heater 9.

[0031] Furthermore, there is no restriction on the conveying length of the plate conveyor belt 1 , and there is no restriction on the coverage area of ​​the hot air hood 6 and the cold air hood 7 , and they can be flexibly adjusted according to production requirements.

[0032] Combination Figure 7 As shown, a grid air groove 102 is provided on the side of the chain plate 11 that contacts the wooden board, and the air holes 101 distributed in an array are all connected to the grid air groove 102, and the grid air grooves 102 extend to the side of the chain plate 11. When the wooden board covers the chain plate 11, the air holes 101 covered by the wooden board are connected to the external environment through the grid air grooves 102.

[0033] In this way, when the hot air hood 6 delivers hot air, the hot air is blown to the surface of the wooden board through the air holes 101, and can flow along the grid air grooves 102, and finally discharged to the external environment, which can also increase the contact area between the hot air and the wooden board, thereby improving the drying effect. Correspondingly, when negative pressure is formed inside the cold air hood 7, the air holes 101 covered by the wooden board draw cold air from the external environment through the grid air grooves 102, and the cold air flowing through the grid air grooves 102 can increase the contact area with the wooden board, thereby improving the drying speed of the wooden board.

[0034] Combination Figure 2 As shown, a plurality of lifting components 5 are provided between the two driving brackets, and the two driving brackets are connected by the lifting components 5. The plurality of lifting components 5 are extended and retracted synchronously, so that the two driving brackets can be moved closer or farther away, so that the height of the clamping gap 103 between the two plate conveyor belts 1 can be adjusted to adapt to the drying of wood boards of different thicknesses.

[0035] In an optional embodiment, the lifting component 5 adopts one of a telescopic cylinder, a pneumatic cylinder or an electric push rod. The lifting component 5 preferably adopts a telescopic cylinder, which has a strong carrying capacity and can meet the lifting and lowering of the driving bracket and the plate conveyor belt 1.

[0036] In a specific embodiment, the driving bracket includes a mounting frame 2 and two supporting rollers 3, the two supporting rollers 3 are respectively connected to the two ends of the mounting frame 2, the plate conveyor belt 1 is wound around the two supporting rollers 3, one end of the mounting frame 2 is provided with a driving component 4, the output end of the driving component 4 is connected to the supporting roller 3 at one end, and the driving component 4 drives the supporting roller 3 to rotate, so that the supporting roller 3 can pull the plate conveyor belt 1 to operate.

[0037] Furthermore, the driving component 4 includes a motor and a reducer. The motor drives the support roller 3 to rotate after being decelerated and torque increased by the reducer.

[0038] Combination Figure 2 and Figure 3 As shown, a connecting frame 21 is provided on the mounting frame 2, the hot air hood 6 and the cold air hood 7 are both installed on the connecting frame 21, and the fan 8 and the heater 9 are fixed on the cold air hood 7, so that the hot air hood 6, the cold air hood 7, the fan 8 and the heater 9 can rise or fall synchronously with the driving bracket.

[0039] Combination Figure 7 and Figure 8 As shown, the plate conveyor belt 1 is composed of a plurality of chain plates 11 hinged to each other, with an axle seat 12 and a support ear 13 respectively provided on both sides of the chain plate 11, and the axle seat 12 and the support ear 13 of two adjacent chain plates 11 are hinged by a connecting shaft, so that the two chain plates 11 can swing relative to each other and form a joint 14, and the joint 14 formed by the axle seat 12 and the support ear 13 is located on the side of the chain plate 11 that does not contact the wooden board, and is located on the flat conveying surface of the chain plate 11.

[0040] Combination Fig. 9 As shown, a groove 301 corresponding to the joint 14 is provided on the support roller 3. When the support roller 3 pulls the plate conveyor belt 1 to operate, the joint 14 engages with the groove 301. The cooperation between the joint 14 and the groove 301 enables the support roller 3 to stably pull the plate conveyor belt 1 to avoid slipping.

[0041] Combination Figure 4 , Figure 5 and Figure 6 As shown, a clearance opening 601 for the joint 14 to pass through is provided at the middle position of the opening ends of the hot air hood 6 and the cold air hood 7, so that when the plate conveyor belt 1 is running, the joint 14 can smoothly pass through the hot air hood 6 and the cold air hood 7 to avoid interference with the joint 14 caused by the hot air hood 6 and the cold air hood 7.

[0042] Combination Figure 1 As shown, the present invention also includes a chassis 100, and the chassis 100 cover is arranged on the outer side of one end of the two plate conveyor belts 1 close to the hot air hood 6, which can reduce heat loss and play a role in heat preservation. At the same time, the cold air hood 7 is not covered, so that the cold air from the external environment can be smoothly introduced into the clamping gap 103.

[0043] Furthermore, the mounting frame 2 at the bottom is provided with supporting legs for stabilizing the supporting device as a whole.

[0044] The working principle of the present invention is as follows: according to the thickness of the wooden board, the clamping gap 103 is adjusted by the lifting component 5, the wooden board is put into the clamping gap 103 at one end of the hot air hood 6, and the wooden board is transported to the direction of the cold air hood 7 by the plate conveyor belt 1. During the transportation process, the wooden board first passes through the hot air hood 6 area, and the air transported by the fan 8 is heated by the heater 9 and then transported to the hot air hood 6 through the air supply pipe 91, so that the hot air in the hot air hood 6 is transported to the clamping gap 103 through the air holes 101, and the wooden board in the clamping gap 103 is dried by hot air. Then, the wooden board passes through the cold air hood 7 area, and the input end of the fan 8 draws the air in the cold air hood 7 through the air duct 81, and a negative pressure is formed in the cold air hood 7. The negative pressure inside the cold air hood 7 is used to make the cold air in the external environment replenish the clamping gap 103, thereby playing a role in cooling the wooden board. During the drying and cooling process, the wooden board is clamped by the plate conveyor belts 1 arranged up and down, which can avoid the bending of the board due to different shrinkage rates.

[0045] In summary of the above embodiments: by setting up two upper and lower plate conveyor belts 1, the two plate conveyor belts 1 can form a clamping gap 103 for clamping the wooden board, and the two plate conveyor belts 1 can convey the wooden board clamped in the clamping gap 103, so that the wooden board is sent from one end of the clamping gap 103 to the other end, and the wooden board can be continuously dried and aired, and the wooden board is clamped during the drying process to avoid bending of the wooden board due to different shrinkage rates.

[0046] When cooling the wooden boards, the fan 8 draws air around the wooden boards, forming a negative pressure around the wooden boards. Under the action of the negative pressure, the cold air in the external environment flows along the wooden boards to cool the wooden boards. After the cold air in the external environment contacts and completes the heat exchange with the wooden boards, the cold air is heated and then introduced into the heater 9 by the fan 8 to be heated and then dry the wooden boards. The waste heat of the wooden boards is used to preheat the air introduced by the fan 8, thereby increasing the temperature of the air introduced by the fan 8 and reducing the energy consumption of the heater 9.
