Description

Technical Field

[0001] The present invention relates to the technical field of log board deformation prevention, in particular to a log board deformation prevention processing device and a processing method thereof. Background Art

[0002] In the wood processing industry, the deformation problem of log boards has always been a key problem that has troubled producers. Log boards are easily deformed during processing or use due to the influence of various factors. This not only affects the appearance quality of the boards, but more seriously reduces their performance, causing economic losses to related industries.

[0003] Wood itself is a natural material with a complex stress structure. After harvesting, the moisture distribution inside the wood is uneven, and during processing, operations such as cutting and drying will further change the stress balance inside the wood. When the stress exceeds the bearing capacity of the wood fiber, the board will deform. Traditional treatment methods are often unable to effectively solve this problem, or the treatment process is not perfect, resulting in the frequent occurrence of deformation problems.

[0004] In addition, the moisture content of wood has a crucial impact on its stability. If the moisture content cannot be accurately controlled during the processing process, or if targeted treatment is not carried out according to the moisture content of different parts of the board, it is easy to cause the local moisture content to be too high or too low, which in turn causes deformation. Moreover, in treatment processes such as heating, simple heating alone is often unable to fully release the internal stress of the wood, and may also cause new stress problems due to local uneven heating. At the same time, excessive water vapor generated during the heating process or failure to be discharged in time may cause the wood to deform. In local areas, excessive water vapor accumulation may cause the wood fibers to over-expand, exceeding their elastic limit. When the water vapor cools or escapes, the wood will leave permanent deformation.

[0020] The present invention provides a device and method for preventing deformation of log boards. Compared with the prior art, it has the following advantages:

[0021] 1. The anti-deformation treatment device and treatment method for log boards use a moisture sensor to continuously detect the moisture content of various parts of the board. The controller accurately adjusts the power of the heating plate according to the detection results to achieve zoned heating. This method can avoid insufficient or excessive heating of certain parts of the board, making the internal fibers of the wood more flexible under moderate heating, which is conducive to stress adjustment, thereby effectively preventing deformation of the board due to stress problems.

[0022] 2. The device and method for preventing deformation of log boards work by squeezing the vibration component during the heating process. The first motor drives the cam to rotate and generate vibration. The cam hits the vibration plate and cooperates with the second spring to greatly increase the vibration of the pressure plate. Vibration is applied to the board during heating, which promotes partial release of internal stress of the board and prevents deformation of the board due to local stress concentration.

[0023] 3. The anti-deformation treatment device and treatment method for log boards, the pretreatment component uses an exhaust pump to extract the water vapor generated by heating, so that it enters the roller and the jet plate in sequence through the first connecting pipe and the rotary joint. On the one hand, the water vapor can heat the roller, and on the other hand, the jet plate can preheat and pre-moisten the surface of the next board to be processed. This method can not only utilize waste water vapor resources, but also balance the moisture content inside and outside the wood, further ensure stress release, and improve treatment efficiency and quality. The roller can automatically adjust its position according to the thickness of the board to ensure that boards of different thicknesses can be effectively treated. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] The present application will be further described in detail below through the accompanying drawings and examples.

[0035] Reference Figures 1 to 7, an embodiment of the present application provides an anti-deformation processing device for log boards, including a processing box 1, a first conveyor belt 6 and a second conveyor belt 7, automatic sealing doors 5 are provided on both sides of the processing box 1, an extrusion vibration component 4 is provided inside the processing box 1, a pretreatment component 2 is provided on the top of the first conveyor belt 6, a heating component 3 is provided between the processing box 1 and the first conveyor belt 6, the heating component 3 includes a bracket 31, the bracket 31 is fixedly installed on the top of the first conveyor belt 6, a moisture content sensor 32 is fixedly installed on the bottom of the bracket 31, a third conveyor belt 9 is fixedly installed on the inner bottom of the processing box 1, a pressing plate 34 is provided above the third conveyor belt 9, a heating plate 35 is fixedly installed on the bottom of the pressing plate 34, a controller 33 is fixedly installed on the top of the processing box 1, the controller 33 is electrically connected to the heating plate 35, and the controller 33 is electrically connected to the moisture content sensor 32. A second motor 48 is fixedly installed on the inner bottom of the processing box 1, and a screw 47 is rotatably connected between the output end of the second motor 48 and the side wall of the processing box 1. The screw 47 is rotatably connected to the processing box 1 and is fixedly connected to the output end of the second motor 48. A moving block 46 is screwed on the outer side of the screw 47. The moving block 46 is slidably connected to the inner bottom of the processing box 1, and a connecting rod 41 is hinged between the moving block 46 and the pressure plate 34.

[0036] In this embodiment, when the stress of the plate is eliminated, the plate is transported by the first conveyor belt 6. When the plate is transported, the plate is transported to the inside of the processing box 1 in conjunction with the third conveyor belt 9. When the plate is transported, the moisture content inside the plate can be detected by the moisture content sensor 32 above, and by continuously detecting the plate, the moisture content of each part of the plate can be detected separately. When the heating plate 35 is started by the controller 33, the heating power of the heating plate 35 can be adjusted according to the moisture content of different positions of the plate. The heating plate 35 can ensure that some parts are not insufficiently heated or overheated during heating by zoned heating of the plates with different moisture contents. After the plate moves to the position, the screw 47 is driven to rotate by starting the second motor 48. The rotation of the screw 47 can drive the moving block 46 on it to move in the opposite direction synchronously. The synchronous reverse movement of the moving block 46 can cooperate with the connecting rod 41 to realize the downward movement of the pressing plate 34. The downward movement of the pressing plate 34 drives the heating plate 35 to fit above the plate. By squeezing and heating the plate, the plate is moderately heated, making the fibers inside the wood more flexible and convenient for stress adjustment.

[0037] Reference Figures 1 to 7In one aspect of this embodiment, the pretreatment assembly 2 includes an air jet plate 25. Support plates 28 are fixedly mounted on either side of the air jet plate 25. A rotary joint 29 is fixedly mounted inside the support plates 28. A roller 26 is fixedly mounted between the two rotary joints 29. The outer section of the rotary joint 29 is fixedly mounted inside the support plates 28, while the inner section of the rotary joint 29 is located inside the support plates 28. The roller 26 is hollow and connected to the rotary joint 29. A second connecting pipe 27 is fixedly mounted between the rotary joint 29 and the air jet plate 25. The second connecting pipe 27 is connected to the rotary joint 29 and the interior of the air jet plate 25. A spray hole is defined at the bottom of the air jet plate 25, and the second connecting pipe 27 and the spray hole are connected to the treatment tank 1. An air pump 21 is fixedly mounted on the top of the treatment tank 1. A first connecting pipe 22 is fixedly mounted between the outlet of the air pump 21 and the rotary joint 29. The first connecting pipe 22 is connected to the interior of the rotary joint 29, and the inlet of the air pump 21 is connected to the interior of the treatment tank 1.

[0038] Side blocks 23 are fixedly mounted on both sides of the first conveyor belt 6. A side frame 24 is fixedly mounted on the top of the side block 23. Sliders 211 are slidably connected to the inside of the side frame 24. The sliders 211 are fixedly mounted on the front and rear sides of the jet plate 25. A slide bar 212 is fixedly mounted inside the side frame 24. The slide bar 212 movably passes through the inside of the slide bar 211. A first spring 210 is fixedly mounted between the bottom of the slide bar 211 and the top of the side block 23. The first spring 210 is sleeved on the outside of the slide bar 212.

[0039] The extrusion vibration assembly 4 includes a vibration plate 42, and second springs 43 are fixedly installed at the four corners of the bottom of the vibration plate 42. The second spring 43 is fixedly installed on the top of the pressure plate 34. A first motor 44 is fixedly installed on the top of the pressure plate 34, and a cam 45 is fixedly installed at the output end of the first motor 44.

[0040] In this embodiment, when the plate is heated, the first motor 44 is started, which drives the cam 45 to rotate. The rotation of the cam 45 generates vibration, and the cam 45 strikes the upper vibration plate 42. In combination with the second spring 43, the vibration generated by the pressing plate 34 can be greatly increased. During the heating process of the plate, the vibration applied by the pressing plate 34 to the plate can partially release the internal stress of the wood, thereby preventing the plate from being deformed due to local stress concentration.

[0041] During heating, more water vapor will be generated, and the generated water vapor will be extracted by the vacuum pump 21. The extracted water vapor will enter the inside of the roller 26 through the first connecting pipe 22 and the rotary joint 29, and heat the roller. The water vapor will then enter the inside of the jet plate 25 through the second connecting pipe 27, and will be ejected through the jet plate 25 to the top of the next plate to be processed above the first conveyor belt 6. When the plate is transported on the first conveyor belt 6, when the plate passes through the roller 26, the roller 26 can be squeezed upward according to the thickness of the wood board, the jet plate 25 and the slider 211 move up along the side frame 24, and the roller 26 can move along the plate. The top of the wood is rotated, and in this way it is ensured that the roller 26 of plates of different thicknesses can roll thereon, and the jet plate 25 can be attached to the top of the plate. The plate can be preheated by the roller 26 and the jet plate 25, and the gas ejected by the jet plate 25 can pre-wet the surface of the plate to a certain extent. A certain amount of moisture on the surface of the wood can balance the moisture content inside and outside the wood, ensuring that there is no large difference in moisture content when the inside and outside are heated, and further ensuring the release of stress; after the processing is completed, the plate is discharged through the second conveyor belt 7 and cooled by the cooling mechanism 8.

[0042] This embodiment also discloses a method for processing a log board anti-deformation processing device, comprising the following steps:

[0043] Step 1: The plate is conveyed to the interior of the processing box 1 via the first conveyor belt 6 and the third conveyor belt 9. The moisture content of the plate is detected by the moisture sensor 32, and the multiple heating plates 35 are controlled to enable different powers.

[0044] Step 2: By pressing the pressing plate 34 and the heating plate 35 against the wooden board, the wooden board is heated and pressed, thereby eliminating the stress inside the board and preventing the board from deforming;

[0045] Step 3: The high-temperature water vapor generated by heating is extracted by the vacuum pump 21 and passed into the roller 26 and the air jet plate 25. By preheating the plate and moistening the surface, the stress relief effect is further improved.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] Working principle: When the plate is undergoing stress elimination, the plate is transported by the first conveyor belt 6, and the plate is transported to the inside of the processing box 1 in conjunction with the third conveyor belt 9. When the plate is being transported, the moisture content inside the plate can be detected by the moisture content sensor 32 above, and by continuously detecting the plate, the moisture content of each part of the plate can be detected separately, and when the heating plate 35 is started by the controller 33, the heating power of the heating plate 35 can be adjusted according to the moisture content of different positions of the plate. The heating plate 35 can ensure that some parts will not be insufficiently heated or overheated during heating by zoned heating of the plate with different moisture contents. After the plate moves to the position, the second motor 48 is started to drive the screw 47 to rotate, and the rotation of the screw 47 can bring The movable block 46 on it moves synchronously in the opposite direction. The synchronous reverse movement of the movable block 46 can cooperate with the connecting rod 41 to realize the downward movement of the pressing plate 34. The downward movement of the pressing plate 34 drives the heating plate 35 to fit above the plate. By squeezing and heating the plate, the plate is moderately heated, making the fibers inside the wood more flexible and easy to adjust the stress. When the plate is heated, the first motor 44 is started, and the first motor 44 drives the cam 45 to rotate. The rotation of the cam 45 generates vibration, and the cam 45 knocks the vibration plate 42 above and cooperates with the second spring 43 to greatly increase the vibration generated by the pressing plate 34. In the process of heating the plate, the vibration applied to the plate by the pressing plate 34 is used to partially release the stress inside the wood, thereby preventing the plate from being deformed due to local stress concentration.

[0048] During heating, more water vapor will be generated, and the generated water vapor will be extracted by the vacuum pump 21. The extracted water vapor will enter the inside of the roller 26 through the first connecting pipe 22 and the rotary joint 29, and heat the roller. The water vapor will then enter the inside of the jet plate 25 through the second connecting pipe 27, and will be ejected through the jet plate 25 to the top of the next plate to be processed above the first conveyor belt 6. When the plate is transported on the first conveyor belt 6, when the plate passes through the roller 26, the roller 26 can be squeezed upward according to the thickness of the wood board, the jet plate 25 and the slider 211 move up along the side frame 24, and the roller 26 can move along the plate. The top of the wood is rotated, and in this way it is ensured that the roller 26 of plates of different thicknesses can roll thereon, and the jet plate 25 can be attached to the top of the plate. The plate can be preheated by the roller 26 and the jet plate 25, and the gas ejected by the jet plate 25 can pre-wet the surface of the plate to a certain extent. A certain amount of moisture on the surface of the wood can balance the moisture content inside and outside the wood, ensuring that there is no large difference in moisture content when the inside and outside are heated, and further ensuring the release of stress; after the processing is completed, the plate is discharged through the second conveyor belt 7 and cooled by the cooling mechanism 8.
