Description

Technical Field

[0001] This utility model relates to the field of flooring production technology, and in particular to a wood-plastic composite flooring composite device. Background Technology

[0002] Flooring is used extensively in people's daily lives. Among them, wood-plastic composite boards made of wood-plastic composite materials are widely used due to their good water resistance and corrosion resistance. After the wood-plastic composite board is processed and formed, a thin film material is often laminated on the surface to enhance the various properties of the composite board. At this time, a lamination device is needed to laminate the wood-plastic composite board and the film.

[0003] Chinese patent CN221249884U discloses a wood-plastic composite flooring composite device, including a base plate. A self-stirring uniform heating roller assembly is fixedly connected to the top right end of the base plate, and a self-stirring uniform heating roller assembly is rotatably connected to the lower end of the base plate. A linkage drive spacing adjustment assembly includes a spacing adjustment component and a linkage drive component. By activating the spacing adjustment component, the spacing adjustment component drives the self-stirring uniform heating roller assembly to adjust the spacing between the upper and lower parts of the self-stirring uniform heating roller assembly. The linkage drive component drives the upper and lower parts of the self-stirring uniform heating roller assembly to move synchronously without being affected by the spacing adjustment of the self-stirring uniform heating roller assembly. Thus, only one drive device is needed to drive the upper and lower parts of the self-stirring uniform heating roller assembly to rotate synchronously without being affected by the spacing adjustment of the self-stirring uniform heating roller assembly.

[0004] However, the aforementioned patents do not provide effective limiting and guiding mechanisms for the conveying and extrusion lamination of wood-plastic composite substrates. During conveying, the substrate is prone to lateral deviation due to its own flexibility and the influence of thickness deviation and speed fluctuation on the conveying mechanism, making it difficult to accurately align with the lamination area of ​​the extrusion rollers. During the extrusion lamination stage, the uneven force on the offset substrate can easily lead to defects such as edge warping, insufficient interlayer bonding, bubbles, and delamination. The offset can also cause uneven edges and dimensional deviations in the formed flooring, requiring additional cutting. Uneven interlayer force can easily lead to the peeling of the flooring decorative surface and cracking of the substrate, shortening the service life. Quality fluctuations also increase production costs and quality inspection pressure. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 A wood-plastic composite flooring assembly, comprising: A base plate 1 is fixedly connected to one side of the surface of the base plate 1. Two parallel extrusion rollers 34 are rotatably arranged on the inner side of the first frame 2. The lower extrusion roller is rotatably connected between the two ends of the inner cavity of the first frame 2 through bearings. The extrusion rollers 34 are used to perform composite pressing on the wood-plastic flooring substrate. A transmission mechanism is provided between the same end of the two extrusion rollers 34 and the first frame 2 to drive the two extrusion rollers 34 to rotate synchronously in opposite directions; The conveying mechanism is fixedly installed on the base plate 1 on one side of the first frame 2, and is used to convey the floor substrate to be laminated to the extrusion roller 34; The limiting mechanism consists of limiting frames 6 symmetrically slidably mounted on the outside of the two extrusion rollers 34. Both limiting frames 6 are U-shaped structures with openings facing upwards. A limiting plate 26 is fixedly connected to one end of each limiting frame 6 near the conveying mechanism, and the bottom ends of both limiting plates 26 are in contact with the conveying surface of the conveying mechanism. The limiting plates 26 are used to limit and guide the side of the floor substrate on the conveying mechanism. An introduction mechanism is fixedly installed on the base plate 1 on one side of the first frame 2 and located outside the conveying mechanism, guiding the floor substrate to be laminated onto the conveying mechanism.

[0019] In the example of this application, the rotatable parallel extrusion rollers 34 can achieve stable composite pressing of the substrate. With the help of the transmission mechanism, the two extrusion rollers 34 are driven to rotate synchronously in opposite directions, avoiding uneven force on the substrate due to inconsistent roller speeds, and ensuring tight bonding between composite layers. The conveying mechanism can stably transport the substrate to be composited to the extrusion rollers 34, reducing substrate shaking during the conveying process. Crucially, the U-shaped limiting frame 6, together with the limiting plate 26 whose bottom end is attached to the conveying surface, can effectively limit and guide the side of the substrate, directly solving the problem of lateral offset of the substrate caused by the lack of limiting in the prior art, ensuring that the substrate is accurately aligned with the composite area of ​​the extrusion rollers 34. The introduction mechanism can smoothly guide the substrate to the conveying mechanism, avoiding subsequent offset caused by initial position deviation when the substrate enters the conveying stage. The whole process of substrate introduction, conveying to extrusion and composite is precisely controlled, improving the molding quality and appearance regularity of wood-plastic composite flooring.

[0020] As a preferred example of this utility model, the transmission mechanism includes a first sprocket 11 fixedly connected to the same end of the two extrusion rollers 34 and a connecting plate 13 fixedly connected to the first frame 2. A second sprocket 12 is connected to the connecting plate 13 via an adjustment component. A chain 18 meshes between the two first sprockets 11 and the second sprocket 12.

[0021] In the example of this application, a stable synchronous transmission structure is constructed through the cooperation of the first sprocket 11, the second sprocket 12 and the chain 18, ensuring that the two extrusion rollers 34 can continuously maintain synchronous rotation in opposite directions, avoiding the slippage or speed deviation problems that are prone to occur in existing transmission structures; at the same time, the adjustment component on the connecting plate 13 can adjust the position of the second sprocket 12, and can adjust it in time according to the tension changes of the chain 18 during use, preventing the chain 18 from failing due to slack, ensuring the long-term stable operation of the transmission mechanism, thereby avoiding uneven extrusion force on the substrate caused by unstable transmission, ensuring the consistency of the composite pressing effect, and reducing defects such as bubbles and delamination caused by transmission problems.

[0022] As a preferred example of this utility model, the adjustment assembly includes an adjustment groove 14 formed on the connecting plate 13 and an adjustment block 17 that is slidably adjusted within the adjustment groove 14. A first lead screw 16 is rotatably connected between the two sides of the inner cavity of the adjustment groove 14, and the adjustment block 17 is threaded onto the outside of the first lead screw 16. The second sprocket 12 is rotatably connected to the adjustment block 17. A first motor 15 is fixedly installed at the end of the connecting plate 13 away from the first frame 2. The drive end of the first motor 15 is connected to the first lead screw 16 via a coupling.

[0023] In the example of this application, the position adjustment of the second sprocket 12 is transformed into a precise mechanical motion driven by the motor through the cooperation of the first lead screw 16, the adjusting block 17 and the first motor 15. No manual adjustment is required, which not only reduces the difficulty of operation, but also avoids the errors that are easy to be generated by manual adjustment. The threaded cooperation between the first lead screw 16 and the adjusting block 17 can realize the smooth fine adjustment of the position of the second sprocket 12, ensuring that the tension of the chain 18 changes gradually during the adjustment process, and will not cause sudden fluctuations in transmission due to excessive adjustment range. This ensures the continuous and stable operation of the transmission mechanism, further improves the stability of the synchronous rotation of the extrusion roller 34, and provides a reliable transmission guarantee for the uniform pressing of the substrate.

[0024] As a preferred example of this utility model, the conveying mechanism includes a mounting frame 27 fixedly connected to the surface of the base plate 1. Two drive rollers 29 are rotatably connected to the inner side of the mounting frame 27. A conveyor belt 30 is provided between the outer sides of the two drive rollers 29. A second motor 28 is fixedly installed at one outer end of the mounting frame 27. The drive end of the second motor 28 is connected to the center of one of the drive rollers 29.

[0025] In the example of this application, the second motor 28 drives the drive roller 29 to drive the conveyor belt 30, which can achieve uniform and stable conveying of the substrate to be laminated. This avoids the speed fluctuation caused by unstable driving in the existing conveying structure and reduces the substrate offset caused by speed changes. The cooperation between the conveyor belt 30 and the drive roller 29 can provide stable support for the substrate and prevent the substrate from warping due to uneven support during the conveying process. With the side limit of the limiting mechanism, it can further ensure that the substrate is accurately conveyed to the extrusion roller 34 along the set path, laying the foundation for accurate alignment in subsequent extrusion lamination and reducing the impact of the conveying process on the lamination quality.

[0026] As a preferred example of this utility model, the introduction mechanism includes a second frame 21 fixedly connected to the base plate 1, a first hydraulic cylinder 22 is mounted on the top of the second frame 21, an installation plate 23 is mounted on the drive end of the first hydraulic cylinder 22, and two staggered introduction rollers 25 are provided at the bottom end of the installation plate 23.

[0027] In the example of this application, the height of the mounting plate 23 and the guide roller 25 can be flexibly adjusted by the first hydraulic cylinder 22, which can adapt to wood-plastic substrates of different thicknesses. This avoids the problem that existing devices cannot adapt to a variety of substrates due to the fixed guide height. The staggered guide rollers 25 can guide substrates of more widths, ensuring that the substrates maintain the correct posture before entering the conveying mechanism and preventing subsequent conveying deviations caused by positional deviations of the substrates during the guide stage.

[0028] As a preferred example of this utility model, a second hydraulic cylinder 4 is fixedly installed on the top of the first frame 2, and an inverted U-shaped frame 3 is fixedly connected to the drive end of the second hydraulic cylinder 4. One of the extrusion rollers 34 is rotatably connected to the inner side of the inverted U-shaped frame 3. A third motor 5 is installed at one end of the inverted U-shaped frame 3, and the drive end of the third motor 5 is connected to the center of one end of the extrusion roller 34 on the inner side of the inverted U-shaped frame 3.

[0029] In the example of this application, the inverted U-shaped frame is driven to move up and down by the second hydraulic cylinder 4, which can flexibly adjust the distance between the two extrusion rollers 34, adapting to the composite needs of wood-plastic flooring substrates of different thicknesses, and solving the problem of fixed distance between extrusion rollers 34 and narrow applicable range in existing devices; the third motor 5 directly drives the extrusion rollers 34 inside the inverted U-shaped frame to rotate, and works with the transmission mechanism to ensure that the two extrusion rollers 34 always rotate in opposite directions synchronously, avoiding damage to transmission synchronization due to distance adjustment, ensuring that substrates of different thicknesses can be subjected to uniform composite pressing force, preventing insufficient pressing of thin substrates or excessive pressing of thick substrates, improving the adaptability of the device to substrates of different specifications and the stability of composite quality, and during adjustment, by adjusting the position of the second sprocket 12, the traction of the chain 18 is prevented from affecting the distance adjustment between the two extrusion rollers 34.

[0030] As a preferred example of this utility model, a sliding groove 7 is provided on the base plate 1 below the two limiting frames 6. Two sliders 10 are slidably connected to the inner cavity of the sliding groove 7. A connecting rod 9 is fixedly connected between the two sliders 10 and the two limiting frames 6. A bidirectional lead screw A8 is threadedly rotatably connected between the two limiting frames 6. The two ends of the bidirectional lead screw A8 are rotatably connected to the inner side of the first frame 2. A fourth motor 20 is installed at one end of the outer side of the first frame 2. The drive end of the fourth motor 20 is connected to one end of the bidirectional lead screw A8 through a coupling.

[0031] In the example of this application, the fourth motor 20 drives the bidirectional lead screw A8 to rotate, causing the two sliders 10 to slide synchronously in opposite directions along the slide groove 7. Then, the connecting rod 9 drives the two limiting frames 6 to adjust the spacing, which can flexibly adapt to wood-plastic substrates of different widths and various specifications of substrates. The cooperation between the slide groove 7 and the slider 10 can ensure that the limiting frame 6 moves smoothly and avoids the limiting frame 6 from deviating during the adjustment process, which would cause the limiting frame to fail. Width adjustment can be achieved without replacing the limiting components. The operation is convenient and can maintain the limiting accuracy for a long time, ensuring that substrates of different widths can be accurately limited, further reducing the lateral deviation of the substrate and ensuring the consistency of composite quality.

[0032] As a preferred example of this utility model, the bottom end of the mounting plate 23 is provided with a limiting groove 31, and two limiting blocks 33 are slidably connected in the limiting groove 31. The bottom ends of the two limiting blocks 33 are fixedly connected to support plates 24. The two guide rollers 25 are respectively rotatably connected to the opposite ends of the two support plates 24. A bidirectional lead screw B19 is rotatably connected between the two sides of the inner cavity of the limiting groove 31, and the two limiting blocks 33 are respectively threaded on the outside of the bidirectional lead screw B19. A fifth motor 32 is fixedly installed at one end of the mounting plate 23, and the drive end of the fifth motor 32 is connected to one end of the bidirectional lead screw B19 through a coupling.

[0033] In the example of this application, the fifth motor 32 drives the bidirectional lead screw B19 to rotate, causing the two limit blocks 33 to slide along the limit groove 31. Then, the support plate 24 adjusts the length between the two staggered ends of the two guide rollers 25 to match the distance between the two limit plates 26, which can adapt to wood-plastic substrates of different widths and avoid the inability to accurately guide wide substrates due to the fixed distance of the existing guide rollers 25.

[0034] Working principle: First, the substrate to be laminated is initially guided by the introduction mechanism. Based on the substrate thickness, the first hydraulic cylinder 22 drives the mounting plate 23 to adjust the height of the introduction roller 25, ensuring the roller 25 adapts to the substrate thickness. Simultaneously, the fifth motor 32 drives the bidirectional lead screw B19 to rotate, causing the limiting block 33 and support plate 24 to adjust the connection length of the two staggered introduction rollers 25. This ensures the staggered introduction rollers 25 provide comprehensive limiting for substrates of different widths, smoothly guiding the substrate to the conveying mechanism. The conveying mechanism then starts, with the second motor 28 driving the drive roller 29 to rotate, causing the conveyor belt 30 to rotate at a uniform speed, conveying the substrate along the set path towards the extrusion roller 34. During this process, the fourth motor 20 drives the bidirectional lead screw A to rotate, which, through the slider 10 and connecting rod 9, drives the two U-shaped rollers... The limiting frame 6 slides synchronously in the opposite direction along the slide groove 7. The spacing of the limiting frame 6 is adjusted to match the width of the substrate. The limiting plate 26 at one end of the limiting frame 6 is attached to the surface of the conveyor belt 30, forming a continuous limiting guide for the side of the substrate, preventing lateral displacement during substrate conveying, and ensuring that the substrate is accurately aligned with the composite area of ​​the extrusion roller 34. When the substrate is conveyed to the extrusion roller 34, according to the substrate thickness requirements, the second hydraulic cylinder 4 drives the U-shaped inverted... The frame moves up and down to adjust the distance between the two extrusion rollers 34. Then, the third motor 5 starts and, in conjunction with the transmission mechanism, drives the two extrusion rollers 34 to rotate synchronously in opposite directions. In the transmission mechanism, the first sprocket 11, the second sprocket 12, and the chain 18 mesh to achieve synchronous transmission. If the chain 18 becomes slack, the first motor 15 can drive the first lead screw 16 to rotate, driving the adjusting block 17 and the second sprocket 12 to move to adjust the tension of the chain 18 and ensure stable transmission. Finally, the two extrusion rollers 34 apply a uniform composite pressing force to the substrate that has been precisely positioned and conveyed, completing the composite pressing operation of the wood-plastic flooring substrate. Throughout the process, the coordinated cooperation of various mechanisms enables precise control of the entire process from substrate introduction and conveying to composite, ensuring the forming quality and appearance regularity of the composite flooring.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
