Description

Technical Field

[0001] The present invention belongs to the technical field of coating curing, and specifically relates to an environment-friendly method and device for rapid curing of wood product surface coatings. Background Art

[0002] In order to rapidly cure the surface coating of wood products and ensure efficient curing of the coating while reducing the emission of volatile organic compounds, it is necessary to use an environment-friendly rapid curing device for wood product surface coatings, optimize the process and waste gas treatment technology to achieve environment-friendly production.

[0003] In the prior art, according to a high-temperature resistant coating for wood products and its preparation method with the application number CN201911081987.3, the coating of this high-temperature resistant coating for wood products includes the following raw materials: methyltrimethoxysilane, natural plant resin, silica sol, glass powder, hydroxy silicone oil, ethanol, animal hide glue, water-soluble amino resin, curing agent, dibutyl phthalate, tackifier, polyvinyl alcohol, corn starch, deionized water. By mixing methyltrimethoxysilane with hydroxy silicone oil due to the methyl group carried by methyltrimethoxysilane itself, the silane is hydrolyzed and polymerized to form silicon-oxygen bonds, improving the weather resistance and temperature resistance of the coating. At the same time, during the mechanical grinding process of the silica sol and glass powder in a nano sand mill, similar compatible chemical bonds are generated, which plays a role in increasing the hardness of the coating and improving the adhesion of the glue. Through this transparent coating system, it can help the moisture attached to the surface quickly form water droplets and promote their detachment from the coating surface, and can protect the coating surface to the greatest extent. Although the high-temperature resistance performance and environmental friendliness of the coating have been significantly improved by optimizing the coating formula, under the conditions of high-temperature rapid curing process, volatile components in the coating, including plasticizers such as hydroxy silicone oil and dibutyl phthalate, solvents such as ethanol, and some unreacted curing agents will still volatilize rapidly, not only producing irritating odors, but also possibly releasing trace amounts of harmful substances. The concentration of harmful substances generated during the centralized curing of wood products is relatively high, and the operation of the filtration system is time-consuming, which is not conducive to the efficiency of curing. Therefore, it is necessary to improve the existing coating rapid curing device. Summary of the Invention

[0012] Preferably, a cylinder is fixedly connected to the middle of the mounting frame, a drying hood is fixedly connected to the output end of the cylinder, and a side wall of the moving block is fixedly connected to the drying hood.

[0013] Preferably, the delayed disturbance mechanism includes an electric heating plate fixed to the inner cavity at the top of the drying hood, the upper inner cavity of the drying hood is slidably connected with a frame, the frame is elastically connected to the drying hood through a second spring, and a plurality of second springs are symmetrically arranged on both sides of the inner cavity of the supporting slot plate.

[0014] Preferably, a plurality of long paddles are equidistantly arranged in the middle of the frame, and the plurality of long paddles are rotatably connected to the frame.

[0015] Preferably, the support groove plate is symmetrically fixed with limit rods on both sides, the outer walls of a pair of limit rods are slidably abutted against the inner cavity of the drying hood, the top inner cavity of the limit rods is rotatably connected with arc edge hooks, and the hook heads of the pair of arc edge hooks are located below the frame.

[0016] Preferably, the arc edge hooks are elastically connected to the limiting rod via a first spring, and the telescopic motion trajectory of the first spring is an arc path that matches the motion trajectory of the arc edge hook.

[0017] Preferably, the cross section of the long strip paddle is arranged in an asymmetric cross shape, and the outer contour of the long strip paddle is ground to form a continuous and smooth curved surface.

[0018] The present application also proposes an environmentally friendly method for rapid curing of a wood product surface coating, the curing method being as follows:

[0019] S1. The painted wood product is first transported to the bottom of the drying hood by the transport assembly. At this time, the cylinder is started to press down the drying hood, and the outer wall of the drying hood is clamped in the middle inner cavity of the supporting slot plate to cover the entire wood product. At the same time, during the pressing process of the drying hood, the moving block slides downward in the slide slot synchronously until the filter group switch is pressed to start the filter assembly, and then the filter assembly is started to circulate and filter the air in the inner cavity of the drying hood, effectively absorbing the odor volatilized during the curing process of the wood product coating;

[0020] S2. While the drying hood is being pressed down, the push rod can also be pressed down synchronously by the moving block. The push rod applies radial pressure to the spiral column sleeve through the spherical protrusion, causing the spiral column sleeve to rotate, thereby pushing the threaded rod connected to the inner wall of the spiral column sleeve to perform upward axial movement. The threaded rod then causes the heat insulation board to move in the same direction through the slider. With the assistance of a pair of running wheels, the heat insulation board moves smoothly upward in the inner cavity of the supporting groove plate until the top of the heat insulation board abuts against the edge of the drying hood, and the wood product is clamped between the heat insulation board and the drying hood in a relatively sealed manner to accelerate the curing effect of the wood product coating.

[0021] S3. When the drying hood is pressed down, its inner cavity and the limit rod slide together to ensure the movement accuracy. At this time, the arc hook is kept extending obliquely under the action of the first spring. When the frame contacts the arc hook, the first spring has a larger elastic force, which pushes the frame upward and stretches the second spring. After the frame reaches the upper limit position and is stuck by the drying hood, continuing to press down will cause the frame to press it back into the limit rod along the arc surface of the arc hook, compressing the first spring until it is detached. After detachment, the arc hook is reset, and the frame vibrates up and down under the action of the second spring and gravity. The asymmetric cross-shaped long strip paddle on it performs a compound motion, moving up and down and rotating back and forth, thereby efficiently diffusing the heat of the electric heating plate to the surrounding of the wooden product and accelerating the curing of the coating.

[0022] S4. The surface coating of the wood product is cured by rapid heat in a relatively sealed environment, and after absorbing the volatile toxic substances, the drying hood is moved upward by contraction of the cylinder. The above steps are reversed to turn off the filter group switch, and the insulation board is moved down and reset to wait for the next operation. Then the transport component continues to transport the cured wood product forward to enter the product cooling and quality inspection stage.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention facilitates the effect of accelerating the curing of the coating on the wood products by arranging the coordination of structures such as a drying hood and a heat insulation board. When the drying hood is pressed down, the push rod applies radial pressure to the spiral column sleeve through the spherical protrusion, causing the spiral column sleeve to rotate, thereby pushing the threaded rod threadedly connected to the inner wall thereof to perform an upward axial movement, and then the heat insulation board is smoothly moved upward in the inner cavity of the supporting groove plate, and the wood products are clamped between the heat insulation board and the drying hood in a relatively sealed manner, so as to achieve the purpose of independently and quickly curing the coating during the transportation of the wood products, and effectively avoid the high concentration of harmful substances generated during the centralized curing of the wood products, thereby reducing the curing efficiency.

[0025] The present invention facilitates the rapid diffusion of heat by arranging the coordination of structures such as arc-edge hooks and long strips of paddles. When the drying hood is pressed down, the frame can also be pushed to contact the arc-edge hooks. Since the elastic force of the first spring is relatively large, after the frame reaches the upper limit position and is stuck by the drying hood, continuing to press down will press the arc-edge hook back into the limit rod. At this time, the frame vibrates up and down under the action of the second spring and gravity, and the asymmetric cross-shaped long strip of paddles thereon performs a compound motion, moving up and down and rotating back and forth, thereby efficiently diffusing the heat of the electric heating plate to the surrounding area of ​​the wooden product, further accelerating the curing of the coating.

[0026] The present invention facilitates the effect of real-time circulation filtering by setting up the cooperation of structures such as moving blocks. When the drying hood is pressed down, the moving block slides downward in the slide groove synchronously until the filter group switch is pressed to start the filter assembly, thereby starting the filter assembly to circulate and filter the air in the inner cavity of the drying hood, and the heat preservation hose of the filter assembly is used to reduce heat loss during the circulation process.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figures 1 to 13 shown, the present invention provides an environmentally friendly rapid curing device for the surface coating of wood products, including a support groove plate 1, a transportation component 2 is installed in the inner cavity of the support groove plate 1, a mounting frame 3 is fixedly connected to the outer wall of the support groove plate 1, a filter component 4 is fixedly connected to the side wall of the mounting frame 3, and further includes:

[0044] The closed and quick-drying mechanism 5 is located in the middle of the mounting frame 3;

[0045] The delay and disturbance mechanism 6 is arranged between the support groove plate 1 and the closed and quick-drying mechanism 5;

[0046] Among them, the closed and quick-drying mechanism 5 includes a downward moving part 51 and an upward moving part 52;

[0047] The upward moving part 52 includes a push rod 521 slidably connected to the inner cavity of the support groove plate 1. The push rod 521 is slidably abutted against a spiral column sleeve 522 through a spherical convex block 525, and the outer wall of the spiral column sleeve 522 is rotatably connected to the inner cavity of the support groove plate 1.

[0048] Adopting the above scheme: The transportation component 2 is mainly composed of components such as a driving motor, a driving wheel, a chain, and a moving roller, and is used for intermittently transporting wood products. The transportation direction of the wood products is Figure 1 the direction of the upper left arrow of the shown transportation component 2. When the wood product is transported below the downward moving part 51, the transportation component 2 stops transporting. After the surface coating of the wood product is quickly cured, the transportation component 2 continues to transport the wood product, and so on, for a streamlined operation.

[0049] As Figure 7 、 Figure 9 and Figure 10 shown, a threaded rod 526 is threadedly connected to the inner cavity of the spiral column sleeve 522. The top of the threaded rod 526 is fixedly connected with a slider 523. The slider 523 is slidably connected to the inner cavity of the support groove plate 1. A heat insulation plate 524 is fixedly connected to the side wall of the slider 523. The heat insulation plate 524 is slidably connected to the middle of the inner cavity of the support groove plate 1 through a walking wheel 527.

[0050] Adopting the above scheme: When the slider 523 pushes the heat insulation plate 524 to move upward, with the auxiliary effect of a pair of walking wheels 527, the heat insulation plate 524 moves smoothly upward in the inner cavity of the support groove plate 1. Through the guiding and auxiliary effect of the walking wheels 527, the heat insulation plate 524 forms a three-point positioning constraint in the inner cavity of the support groove plate 1, effectively suppressing radial yaw and axial movement. And the surface of the heat insulation plate 524 is provided with an arc-shaped groove adapted to the moving roller of the transportation component 2. While increasing the tightness of the fit between the heat insulation plate 524 and the drying hood 512, it can also limit the position of the moving roller to ensure the effective positioning of the wood product placed on the moving roller.

[0051] As Figures 3 to 6As shown in the figure, the downward moving part 51 includes a moving block 513 fixedly connected to the top of the push rod 521. A sliding groove 514 is formed in the side wall of the mounting frame 3. The moving block 513 slides through the sliding groove 514. A filter group switch 515 is fixedly connected to the outer wall of the mounting frame 3 near the bottom of the sliding groove 514. The moving block 513 is located above the filter group switch 515. A cylinder 511 is fixedly connected to the middle of the mounting frame 3. The output end of the cylinder 511 is fixedly connected with a drying hood 512. The side wall of the moving block 513 is fixedly connected to the drying hood 512.

[0052] Adopting the above scheme: The filtering component 4 is mainly composed of an air pump, a filter and a heat preservation hose. The filtering component 4 is circularly connected to the drying hood 512 through a pair of heat preservation hoses, and the air flow circulation direction is as Figure 1 and Figure 3 shown by the arrows. The air enters the heat preservation hose from one side of the drying hood 512, and after passing through the filter to filter out harmful substances, it is continuously pumped into the heat preservation hose on the other side by the air pump, and finally flows back into the drying hood 512 to ensure that the harmful substances volatilized during the curing of the wood product coating are absorbed in time. The heat preservation hose can ensure that the drying hood 512 is always effectively connected to the filtering component 4 during the movement process. Open slots for clamping the chains on both sides of the transportation component 2 are symmetrically arranged at the bottom of the drying hood 512, so that the drying hood 512 can be clamped in the middle inner cavity of the support groove plate 1, reducing the heat loss in the inner cavity of the drying hood 512. The filter group switch 515 is electrically connected to the filtering component 4, and the height and size of components such as the drying hood 512 are configured according to the actual size of the wood product.

[0053] As Figure 5 、 Figure 8 、 Figures 11 to 13 shown in the figure, the delay disturbance mechanism 6 includes an electric heating plate 67 fixedly connected to the inner cavity of the top of the drying hood 512. A frame 64 is slidably connected to the upper inner cavity of the drying hood 512. The frame 64 is elastically connected to the drying hood 512 through a second spring 65. A plurality of second springs 65 are symmetrically arranged on both sides of the inner cavity of the support groove plate 1. Preferably, a plurality of long strip paddles 66 are arranged at equal intervals in the middle of the frame 64. A plurality of long strip paddles 66 are all rotatably connected to the frame 64. The cross section of the long strip paddle 66 is arranged in an asymmetric cross shape, and the outer contour of the long strip paddle 66 is ground to form a continuous and smooth curved surface.

[0054] As Figure 5 and Figure 8 shown in the figure, limiting rods 61 are symmetrically fixedly connected to both sides of the support groove plate 1. The outer walls of a pair of limiting rods 61 are all slidably abutted against the inner cavity of the drying hood 512. Arc-shaped hooks 62 are rotatably connected to the inner cavities of the tops of the limiting rods 61. The hook heads of a pair of arc-shaped hooks 62 are both located below the frame 64. The arc-shaped hooks 62 are all elastically connected to the limiting rods 61 through first springs 63. The telescopic movement track of the first spring 63 is an arc path matching the movement track of the arc-shaped hook 62.

[0055] Adopting the above solution: The elastic force of the first spring 63 is greater than that of the second spring 65, which is used to ensure that the arc-edge hook 62 remains in the extended state and pushes the frame 64 upward, achieving the effect of delayed release. In cooperation with the cross-section of the long strip flap 66 on the frame 64 being arranged in an asymmetric cross shape, when the frame 64 reciprocates up and down, it can drive the long strip flap 66 to move up and down, and at the same time, the long strip flap 66 itself also makes a reciprocating rotational swing motion, achieving the effect of evenly disturbing the air flow in the inner cavity of the drying hood 512, so that the surface of the wooden product is quickly heated.

[0056] The working principle and usage process of the present invention:

[0057] S1. The wooden product coated with paint is first transported by the transportation component 2 to the lower part of the drying hood 512. At this time, the air cylinder 511 is started to press down the drying hood 512. The outer wall of the drying hood 512 is clamped in the middle inner cavity of the support groove plate 1 to cover the entire wooden product. At the same time, during the downward pressing process of the drying hood 512, the moving block 513 slides downward in the sliding groove 514 synchronously until the filter group switch 515 is pressed to start, and then the filtering component 4 is started to circulate and filter the air in the inner cavity of the drying hood 512, effectively absorbing the odor volatilized during the curing process of the wooden product coating.

[0058] S2. While the drying hood 512 is being pressed down, the push rod 521 can also be synchronously pressed down by the moving block 513. The push rod 521 applies a radial pressure to the spiral column sleeve 522 through the spherical convex block 525, causing the spiral column sleeve 522 to rotate, and then pushing the threaded rod 526 threadedly connected to its inner wall to move axially upward. The threaded rod 526 then drives the heat insulation plate 524 to move in the same direction through the slider 523. With the assistance of a pair of traveling wheels 527, the heat insulation plate 524 moves smoothly upward in the inner cavity of the support groove plate 1 until the top of the heat insulation plate 524 abuts against the edge of the drying hood 512, clamping the wooden product between the heat insulation plate 524 and the drying hood 512 in a relatively sealed manner to accelerate the curing effect of the wooden product coating.

[0059] S3. When the drying hood 512 is pressed down, its inner cavity is in sliding fit with the limit rod 61 to ensure the movement accuracy. At this time, the arc-edge hook 62 remains obliquely extended under the action of the first spring 63. When the frame 64 contacts the arc-edge hook 62, due to the greater elastic force of the first spring 63, it pushes the frame 64 upward and stretches the second spring 65. After the frame 64 reaches the upper limit position and is stuck by the drying hood 512, continuing to press down will cause the frame 64 to press the arc-edge hook 62 back into the limit rod 61 along the arc surface of the arc-edge hook 62, compressing the first spring 63 until it disengages. After disengagement, the arc-edge hook 62 resets, and the frame 64 vibrates up and down under the action of the second spring 65 and gravity, and the asymmetric cross-shaped long strip flap 66 on it makes a compound motion, moving up and down and reciprocatingly rotating, so as to efficiently spread the heat of the electric heating plate 67 to the surrounding of the wooden product, further accelerating the coating curing.

[0060] S4. Under a relatively sealed environment, the surface coating of the wood product is rapidly heated and cured. After absorbing the volatile toxic substances, the drying hood 512 is lifted by the contraction of the air cylinder 511. By operating in the reverse direction in the same way as the above steps, the filter group switch 515 is closed, and the heat insulation plate 524 moves downward to reset, waiting for the next operation. Then, the transportation component 2 continues to transport the cured wood product forward and enters the product cooling and quality inspection stage.

The push rod (521) applies radial pressure to the spiral column sleeve (522) through the spherical protrusion (525), causing the spiral column sleeve (522) to rotate, thereby pushing the threaded rod (526) connected to the inner wall of the spiral column sleeve to perform an upward axial movement. The threaded rod (526) then drives the heat insulation board (524) to move in the same direction through the slider (523). With the assistance of a pair of running wheels (527), the heat insulation board (524) moves smoothly upward in the inner cavity of the supporting groove plate (1) until the top of the heat insulation board (524) abuts against the edge of the drying hood (512), and the wooden product is sandwiched between the heat insulation board (524) and the drying hood (512) in a relatively sealed manner, so as to accelerate the curing effect of the coating on the wooden product. S3, when the drying cover (512) is pressed down, its inner cavity and the limit rod (61) slide together to ensure the movement accuracy. At this time, the arc hook (62) keeps extending obliquely under the action of the first spring (63). When the frame (64) contacts the arc hook (62), the first spring (63) has a large elastic force, which pushes the frame (64) upward and stretches the second spring (65). After the frame (64) reaches the upper limit position and is stuck by the drying cover (512), continuing to press down will cause the frame (64) to press the arc hook (62) back into the limit rod (61) along the arc surface, compressing the first spring (63) until it is detached. After detachment, the arc hook (62) is reset, and the frame (64) vibrates up and down under the action of the second spring (65) and gravity. The asymmetric cross-shaped long strip paddle (66) thereon performs a compound motion, moving up and down and rotating back and forth, thereby efficiently diffusing the heat of the electric heating plate (67) to the surrounding of the wooden product, accelerating the curing of the coating; S4. The coating on the surface of the wood product is cured by rapid heat in a relatively sealed environment and absorbs the volatile toxic substances. The cylinder (511) is retracted to move the drying cover (512) upward. The operation is reversed in the same way as the above steps. The filter group switch (515) is turned off and the heat insulation board (524) is moved downward to reset and wait for the next operation. Then, the transport component (2) continues to transport the cured wood product forward and enters the product cooling and quality inspection stage.
