Description

Technical Field

[0001] This invention relates to the field of board manufacturing technology, and specifically to a glue-free composite board manufacturing method based on multiple waste materials. Background Technology

[0002] Traditional MDF production requires large quantities of timber, and with the continuous depletion of global forest resources, timber supply is becoming increasingly strained. Furthermore, the production process involves the use of large amounts of glue, which contains harmful substances such as formaldehyde, posing a threat to both the environment and human health. Therefore, finding a new material that can replace both timber and glue has become an urgent problem to solve.

[0003] With increasing environmental awareness and the demand for sustainable development, glue-free composite board manufacturing technology using waste materials is gradually becoming a new method to replace traditional MDF production. Glue-free composite board manufacturing technology is a novel technology for producing boards using waste materials. This technology uses various waste materials, such as cotton, linen, and auxiliary materials like plastic granules and fibers, to transform them into reusable fiber materials through physical and chemical treatment. After mixing, molding, drying, and high-temperature, high-pressure processing, these fiber materials form boards with ultra-high strength and a certain degree of toughness, which can replace MDF. Because this technology does not require the use of glue, it can effectively reduce the emission of harmful substances such as formaldehyde, reduce environmental pollution, solve some waste disposal problems, and improve resource utilization. Therefore, those skilled in the art provide a glue-free composite board manufacturing method based on multiple waste materials to solve the problems mentioned in the background art. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a method for producing adhesive-free composite boards based on multiple waste materials. The method includes a device base, with a heating module fixedly installed at the upper center of the base. Steel frames are positioned at both ends of the heating module and are fixedly installed on the upper part of the device base. The front and rear ends of the steel frames are symmetrically fixed with bolts. A hydraulic device is fixedly installed on the upper end of the fixed steel frame on the same side. A hydraulic mold is placed between the hydraulic device and the heating module. A locking module is fixedly installed at the center of the side end face of the hydraulic mold. A decompression module is connected to the locking module and is fixedly installed on the device base. An unlocking module is fixedly installed on the lower side between the fixed steel frames. The unlocking module releases the locking module, causing the hydraulic mold to separate.

[0005] This invention is achieved through the following technical solution:

[0006] S1. First, the plastic substrate made of PET fiber formed by processing bamboo fiber, cotton linen, and polyester and low melting point modified fiber is added into the bottom pressure groove plate and waited for pressing to form a plate.

[0007] S2. Next, the heating module is electrically heated until the plastic substrate melts. The hydraulic device is activated so that the upper pressure plate covers the bottom pressure groove plate and the molding plate presses down on the plastic substrate. The plastic substrate is compressed and composited under pressure. The gas in its cavity enters the pressure groove through the overflow groove to ensure that no air bubbles are generated in the composite pressing plate, which would affect the strength of the plate.

[0008] S3. Next, after the hydraulic mold compresses the plastic substrate to the set thickness of the board, the hooks on its upper and lower symmetrical locking seats rotate around a fixed axis to achieve the interlocking correspondence between the hooks.

[0009] S4. Then, drive the servo motor to rotate the threaded bolt. The threaded bolt engages with the limit seat, which causes the threaded seat to drive the limit rod in the upper sliding hole plate of the top seat to slide in the long hole and push the locking pin to slide inward in the through hole. The notch on the hook and the locking pin are used to lock together to ensure the stable pressure of the locking mold.

[0010] S5. Next, the heating module is heated by temperature control through an external control terminal to make the materials stick together tightly until the plate making is completed. Then, the heating module is turned off and the material plate is taken out of the mold.

[0011] S6. Finally, the drive cylinder pushes the movable seat on the movable sleeve shaft to drive the ring to rotate circumferentially, thereby causing the sleeve teeth to rotate. The sleeve teeth mesh and rotate with the meshing teeth on the lower side, and the meshing teeth mesh and rotate with each other. This causes the optical shaft to drive the cam on the limit tube clamp two to rotate. According to the change of the cam radius, the locking pin deformed by pressure is disengaged from the through hole, releasing the hook lock of the locking module and taking out the plate that has been made.

[0012] Preferably, the hydraulic mold includes an upper pressure plate, a bottom pressure groove plate, a molding plate, an overflow groove, and a pressure groove.

[0015] Preferably, the movable locking groove has a through hole in the middle of the bottom, and a slidable locking pin is provided in the through hole. A locking clip is fixedly installed on the inner end of the locking pin. The locking clip is set in accordance with the notch. By pushing the locking clip on the locking pin to slide inward on one side of the through hole, the notch on the hook and the locking clip are locked together to ensure the stable pressure of the locking mold. A through elongated hole is provided in the middle of the outer end of the locking pin, and the elongated hole corresponds to the decompression module.

[0016] Preferably, the decompression module includes a fixed base, a connector, a limiting groove, a threaded rod, a servo motor, a positioning seat, a telescopic rod, a limiting female seat, a top seat, a sliding plate, a long sliding hole, and a limiting rod. The fixed base is fixed to the periphery of the heating module and is located outside the locking module. Connectors are symmetrically fixed at both ends of the fixed base. The connectors are fixedly connected to the heating module and the frame steel. A limiting groove is opened in the middle of the upper end face of the fixed base. A threaded rod is provided in the limiting groove. The end of the threaded rod passes through the fixed base and is fixedly connected to the output shaft of the servo motor. A limiting female seat is placed in the limiting groove. The limiting female seat and the threaded rod are threadedly engaged, so that the limiting female seat can slide freely in the limiting groove.

[0017] Preferably, a top seat is fixedly installed on the upper end of the limiting female seat, and a sliding hole plate is fixedly installed on the upper end face of the top seat with bolts on both sides. A long sliding hole is opened in the middle of the sliding hole plate, and a limiting rod is symmetrically set between the long sliding holes. The limiting rod slides corresponding to the long hole.

[0018] Preferably, a positioning seat is fixedly installed in the middle of the fixed seat, and a telescopic rod is slidably installed on the inner end face of the positioning seat, and the telescopic rod is fixedly connected to the locking pin.

[0019] Preferably, the unlocking module includes a fixed shaft plate, a fixed shaft, a sleeve tooth, a ring, a movable seat, a movable sleeve shaft, a propulsion cylinder, a light shaft, a first limiting tube clamp, a meshing tooth, a second limiting tube clamp, and a cam. A symmetrical light shaft is provided between the lower parts of adjacent fixed steel frames. The second limiting tube clamp is locked and installed in the middle of the light shaft.

By controlling the propulsion cylinder to push the movable seat on the movable sleeve shaft, the ring rotates circumferentially, thereby causing the sleeve tooth to rotate. The sleeve tooth meshes and rotates with the meshing teeth on the lower side, and the meshing teeth mesh and rotate with each other. This causes the optical axis to drive the cam on the second limiting tube clamp to rotate. According to the change in the radius of the cam, the locking pin deformed by pressure is disengaged from the through hole, releasing the hook lock of the locking module and taking out the plate after the plate making is completed.

[0021] The technical effects and advantages of this invention are as follows:

[0022] 1. When using this invention, by employing multiple fibers to make the board, waste resources can be effectively recycled and reused. Furthermore, the plastic fiber substrate used in the board making process isolates the colloid, replacing the emission of harmful substances and gases produced by other materials in board making. It also combines the advantages of multiple fiber materials to form a material with high strength and toughness.

[0023] 2. When using this invention, during the plate-making process, the locking pin is pushed to slide inward on one side of the through hole, thereby using the notch on the hook to lock against the locking pin, ensuring stable pressure on the locking mold and achieving pressure holding. This helps to improve the structural density of the material, reduce the internal porosity of the material, and make the metallographic structure of the material more compact. This not only enhances the mechanical properties of the material, such as toughness, strength, and rigidity, but also optimizes the material's microstructure, promotes grain homogenization, and thus improves the overall performance of the material. Furthermore, it can prevent deformation, separation, and damage during the processing of the material, thereby improving the service life and stability of the material. At the same time, it can also avoid the generation of cracks and defects in the material, ensuring the stability and reliability of product quality, and helping to reduce production costs and improve production efficiency.

[0024] 3. When using this invention, the heating module is heated by an external control terminal, which helps to maintain the internal temperature stability of the board and ensures that the material is not affected by temperature fluctuations during processing. The stable temperature environment helps to promote the chemical reaction and physical change inside the material, making the structure of the board more uniform and dense, thereby improving its overall performance and reducing the internal stress and shrinkage deformation generated during the cooling process.

[0025] 4. In use, this invention uses a propulsion cylinder to drive a cam to push the locking pin out of the through hole, mechanically opening the mold. Compared to traditional manual mold opening, this is faster and more accurate, significantly reducing mold opening time and accelerating the entire production process. This is especially important for large-scale, high-frequency production needs, helping companies improve capacity and efficiency. It also ensures product precision and quality. Through precisely controlled mechanical movement, the mold opens accurately, ensuring the product is smoothly removed from the mold without damage. This helps maintain product consistency, reduce defect rates, and improve overall product quality. Attached Figure Description

[0042] Please see Figure 6As shown, the unlocking module 8 includes a fixed shaft plate 81, a fixed shaft 82, a sleeve tooth 83, a ring 84, a movable seat 85, a movable sleeve shaft 86, a propulsion cylinder 87, an optical shaft 88, a first limiting clamp 89, a meshing tooth 810, a second limiting clamp 811, and a cam 812. Optical shafts 88 are symmetrically arranged between the lower parts of adjacent fixed steel frames 4. The second limiting clamp 811 is locked and installed in the middle of the optical shaft 88. A cam 812 is sleeved on the second limiting clamp 811, and the cam 812 abuts against the locking piece 69. A first limiting clamp 89 is locked and installed on one side of the optical shaft 88. A meshing tooth 810 is sleeved on the upper end of the first limiting clamp 89, and the meshing teeth 810 mesh and rotate with each other.

The push cylinder 87 is fixedly installed on the device base 1. By controlling the push cylinder 87 to push the movable seat 85 on the movable sleeve shaft 86, the ring 84 is driven to rotate circumferentially, thereby causing the sleeve tooth 83 to rotate. The sleeve tooth 83 meshes and rotates with the meshing tooth 810 on the lower side. The meshing teeth 810 mesh and rotate with each other, thereby causing the optical shaft 88 to drive the cam 812 on the limit tube clamp 811 to rotate. According to the change of the radius of the cam 812, the locking pin 68 deformed by pressure is disengaged from the through hole 64, releasing the hook lock of the locking module 6 and taking out the plate after the plate making is completed.

[0043] The device of the present invention is implemented through the following technical solution, including the following steps:

[0044] S1. First, the plastic substrate made of PET fiber formed by processing bamboo fiber, cotton linen, and polyester and low melting point modified fiber is placed into the bottom pressure groove plate 92 and waited for pressing to form a plate.

[0045] S2. Next, the heating module 2 is electrically heated until the plastic substrate is melted. The hydraulic device 5 is activated so that the upper pressing template 91 covers the bottom pressing groove plate 92 and the molding plate 93 presses down on the plastic substrate. The plastic substrate is compressed and composited under pressure. The gas in its cavity enters the pressure groove 95 through the overflow groove 94 to ensure that no air bubbles are generated in the composite pressing plate, which would affect the strength of the plate.

[0046] S3. Next, when the hydraulic mold 9 compresses the plastic substrate to the set thickness of the board, the hooks 66 on its upper and lower symmetrical locking seats 62 rotate around the fixed axis 65 to realize the interlocking correspondence between the hooks 66.

[0047] S4. Then, drive the servo motor 75 to rotate the threaded bolt 74. The threaded bolt 74 engages with the limit seat 78, so that the threaded seat 78 drives the limit rod 712 in the upper sliding hole plate 710 of the top seat 79 to slide in the long hole 610, and pushes the locking piece 69 on the locking pin 68 to slide inward in the through hole 64. Thus, the notch 67 on the hook 66 and the locking piece 69 are locked together to ensure the stable pressure of the locking mold.

[0048] S5. Next, the heating module 2 is heated by the external control terminal to make the materials stick together tightly until the plate making is completed. Then, the heating module 2 is turned off and the material plate is taken out from the mold.

[0049] S6. Finally, the drive cylinder 87 pushes the movable seat 85 on the movable sleeve shaft 86 to drive the ring 84 to rotate circumferentially, thereby causing the sleeve tooth 83 to rotate. The sleeve tooth 83 meshes and rotates with the meshing tooth 810 on the lower side, and the meshing teeth 810 mesh and rotate with each other, thereby causing the optical shaft 88 to drive the cam 812 on the limit tube clamp 811 to rotate. According to the change in the radius of the cam 812, the locking pin 68 deformed by pressure is disengaged from the through hole 64, releasing the hook lock of the locking module 6 and taking out the plate that has been made.

[0050] In this invention, multiple fibers are used for board making, which can effectively recycle waste resources. The plastic fiber substrate used in the board making process isolates the colloid, replacing the emission of harmful substances and gases produced by other materials. It combines the advantages of multiple fiber materials to form a material with high strength and toughness. During the board making process, the locking element 69 on the locking pin 68 slides inwards through the through hole 64, thereby using the notch 67 on the hook 66 to engage with the locking element 69, ensuring stable pressure on the locking mold and achieving pressure holding. This helps to improve the structural density of the material, reduce the internal porosity, and make the metallographic structure of the material more compact. This not only enhances the mechanical properties of the material, such as toughness, strength, and rigidity, but also optimizes the material's microstructure, promotes grain homogenization, and thus improves the overall performance of the material. Furthermore, it can prevent deformation, separation, and damage during processing, thereby improving the material's service life and stability. Simultaneously, it can avoid the generation of cracks and defects in the material, ensuring stable product quality. The high performance and reliability of the heating module 2 help reduce production costs and improve production efficiency. Simultaneously, the external control terminal provides temperature control for the heating module 2, helping to maintain stable internal temperatures in the material. This ensures that the material is not affected by temperature fluctuations during processing. A stable temperature environment promotes chemical reactions and physical changes within the material, resulting in a more uniform and dense structure, thus improving overall performance and reducing internal stress and shrinkage deformation during cooling. Finally, the cylinder 87 drives the cam 812 to push out the locking pin 68 from the through hole 64, mechanically opening the mold. This is faster and more accurate than traditional manual mold opening, significantly shortening opening time and accelerating the entire production process. This is particularly important for large-scale, high-frequency production needs, helping companies improve capacity and efficiency, and ensuring product precision and quality. Through precisely controlled mechanical movement, the mold opens accurately, ensuring the product is smoothly removed from the mold without damage. This helps maintain product consistency, reduce defect rates, and improve overall product quality.

5. The method for producing adhesive-free composite boards based on multiple waste materials according to claim 4, characterized in that, The method includes the following steps: S1. First, the plastic substrate made of PET fiber formed by processing bamboo fiber, cotton linen, and polyester and low melting point modified fiber is placed into the bottom pressure groove plate (92) and waited for pressing to form a plate. S2. Next, the heating module (2) is electrically heated until the plastic substrate is melted. The hydraulic device (5) is started so that the upper pressure plate (91) covers the bottom pressure groove plate (92) and the molding plate (93) presses down on the plastic substrate. The plastic substrate is compressed and composited under pressure. The gas in its cavity enters the pressure groove (95) through the overflow groove (94) to ensure that no bubbles are generated in the composite pressing plate, which affects the strength of the plate. S3. Next, when the hydraulic mold (9) compresses the plastic substrate to the set thickness of the board, the hooks (66) on its upper and lower symmetrical locking seats (62) rotate around the fixed axis (65) to realize the buckling correspondence between the hooks (66); S4. Then, drive the servo motor (75) to rotate the threaded rod (74). The threaded rod (74) and the limiting female seat (78) are threadedly engaged, so that the threaded female seat (78) drives the limiting rod (712) in the upper sliding hole plate (710) of the top seat (79) to slide in the long hole (610) and push the locking piece (69) on the locking pin (68) to slide inward in the through hole (64). Thus, the notch (67) on the hook (66) and the locking piece (69) are locked together to ensure the stable pressure of the locking mold. S5. Next, the heating module (2) is heated by the external control terminal to make the materials stick together tightly until the plate making is completed. Then, the heating module (2) is turned off and the material plate is taken out from the mold. S6. Finally, the drive cylinder (87) pushes the movable seat (85) on the movable sleeve shaft (86) to drive the ring (84) to rotate circumferentially, thereby causing the sleeve tooth (83) to rotate. The sleeve tooth (83) meshes and rotates with the meshing tooth (810) on the lower side, thereby causing the optical shaft (88) to drive the cam (812) on the limit tube clamp (811) to rotate. According to the change in the radius of the cam (812), the pressure-deformed locking pin (68) is disengaged from the through hole (64), the hook lock of the locking module (6) is released, and the plate material that has been made is taken out.
