[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0055] Example 1

[0056] like Figures 1 to 3 As shown, a high-density laminated fiberboard based on cotton stalks includes a board body 100, the board body 100 is provided with multiple layers to form a composite layered structure, the multiple layers of the board body 100 are provided with a pattern group, the pattern group includes a first pattern 101 and a second pattern 102, the first pattern 101 and the second pattern 102 are respectively provided on different board bodies 100, and the stress in the board body 100 is absorbed by providing the first pattern 101 and the second pattern 102;

[0057] The multi-layer board body 100 includes a first decorative layer, a core layer, and a second decorative layer from top to bottom, and a bottom plate pad is provided at the bottom of each layer. The bottom plate pad at the bottom of the second decorative layer is smooth on the side away from the decorative layer, and the bottom plate pad at the bottom of the first decorative layer and the core layer is rough on both sides. The core layer is made of thermoplastic adhesive fibers and base fibers bonded together. The thermoplastic adhesive fibers are melted and connected to the base fibers after being heated, and form a fiber structure with the base fibers after cooling. The thermoplastic adhesive fibers include high-density polyethylene fibers, which have high strength and rigidity to increase the overall strength, the length of the high-density polyethylene fiber is in the range of 5mm to 15mm, the base fiber includes cotton stalk fiber, the length of the cotton stalk fiber is in the range of 2mm to 6mm, and the cotton stalk fiber accounts for 32% to 48% of the weight of the core layer, the base fiber also includes short PET fiber and long PET fiber, the length of the short PET fiber is in the range of 2mm to 10mm, the length of the long PET fiber is in the range of 10mm to 20mm, and the short PET fiber accounts for 38% to 58% of the weight of the core layer, and the first pattern 101 and the second pattern 102 represent the arrangement direction of the thermoplastic bonding fiber or the base fiber;

[0058] The bottom plate pad is attached to the lower surface of the first decorative layer, the second decorative layer and the core layer to provide a flat and / or solid surface to support the integral fiberboard and to constitute protection and buffering vibration isolation. The bottom plate pad can be foam, particle board, cork or felt sheet. The thickness of the bottom plate pad is in the range of 3 mm to 6 mm.

[0059] The first decorative layer and the second decorative layer are made directly of base fibers. In order to manufacture the first decorative layer and the second decorative layer, the base fibers are laid on the bottom plate pad. The base fibers can flow under the influence of external force to form the first pattern 101, wherein the surface of the first decorative layer is also provided with a wear-resistant layer, which is protected from scratches and stains by the wear-resistant layer. The wear-resistant layer is made of aluminum oxide or polyurethane.

[0060] In order to manufacture the core layer, the thermoplastic bonding fibers are randomly distributed within the base fibers to form a fiber mixture, and the fiber mixture is compressed by a compression type oven. The oven compresses the fiber mixture while heating the fiber mixture. When the oven heats the fiber mixture, the thermoplastic bonding fibers melt and bond the base fibers in the mixture. After the fiber mixture leaves the oven, the fiber mixture cools, and the melted thermoplastic bonding fibers solidify and bond the base fibers together to form a fiber structure, which has flexibility so that the second pattern 102 can be formed by an external force.

[0061] like Figures 1 to 3As shown, in a specific embodiment, the first patterns 101 are arranged in concentric rings, and the circular arrangement of the first patterns 101 is used to absorb the stress generated by the plate body 100 and ensure the uniform strength of the plate body 100;

[0062] The second pattern 102 is V-shaped and arranged in a rectangular shape along the board 100. The V-shape of the second pattern 102 is used to form a skeleton structure of the board 100, and the rectangular arrangement of the second pattern 102 is used to ensure that the strength of the board 100 is uniform to the edge position;

[0063] The bending stress generated when the plate body 100 where the second pattern 102 is located is bent and deformed is transferred to the plate body 100 where the first pattern 101 is located, and the bending stress is absorbed under the action of the first pattern 101. The tensile force generated when the plate body 100 where the first pattern 101 is stretched is transferred to the plate body 100 where the second pattern 102 is located, and acts on the skeleton structure formed by the second pattern 102. In this setting, the circular arrangement of the first pattern 101 makes the tensile strength of the plate body 100 in any direction the same, greatly strengthens the tensile strength of the plate body 100, and reduces the internal stress of the plate body 100 itself; the skeleton structure formed by the second pattern 102 is conducive to enhancing the overall bending resistance of the plate body 100.

In this configuration, the fourth sliding device 602 is started, the fourth sliding device 602 drives the mounting block 700 to move, and the mounting block 700 drives the clamping plate 703 to move. When the clamping plate 703 abuts against the third sliding device 601, the mounting block 700 continues to move and pushes the clamping plate 703 through the push plate 705. At this time, the clamping plate 703 moves to one side and extends toward the plate body 100. At the same time, relative sliding occurs between the insertion block 701 and the mounting block 700. When the rotating plate 710 is staggered with the mounting block 700 and is in the torsion spring 711, When it pops up under the action, the rotating plate 710 presses against the mounting block 700, and the fourth sliding device 602 is moved in the opposite direction, and the board body 100 is driven to move to the second laminator 604 through the clamping plate 703. When the board body 100 completely enters the second laminator 604, the support plate 712 presses against the rotating plate 710 to reset it, so that the insert block 701 can enter the mounting block 700 and can be reset by the spring 708. At the same time, the second laminator 604 laminates multiple board bodies 100 to form a composite layered structure.

[0082] The first sliding device 500 , the second sliding device 600 , the third sliding device 601 and the fourth sliding device 602 all use electric slide rails.

[0083] The electric slide rail, the permanent magnet motor, the first laminator 402 and the second laminator 604 are all programmed and controlled by a PLC control circuit.

[0084] The implementation principle of the laminating device of the high-density laminated fiberboard based on cotton stalks in this embodiment is as follows: when working, add cotton stalk fibers into the placement frame 503, start the power source 400, and drive the first flower making unit and the second flower making unit to work through the chain device 401;

[0085] When the first pattern making unit is working, the transmission shaft 202 drives the first bottom plate 203 to rotate, and the first bottom plate 203 drives the slider 205 to rotate. At this time, the slider 205 drives the guide rod 206 to slide in the guide rail 201. At the same time, the slider 205 moves with the roller 207. The roller 207 rotates under the action of the first mounting shell 200 and drives the pick needle 209 to move up and down through the connecting rod 208. At this time, the pick needle 209 moves up and down while moving along the guide rail 201 to form the second pattern 102;

[0086] When the second flower making unit is working, the belt column 304 drives the drum 302 to rotate through the belt 303. Since the diameters of the drums 302 are different, when the belt column 304 engages with the drums 302 of different diameters through the belt 303, the angular velocities of the drum 302 are different, thereby causing a misalignment phenomenon, and the cotton stalk fibers are moved to form the first pattern 101.

[0087] The cotton stalk fibers processed by the first flower making unit and the second flower making unit are transported to the bottom of the first laminator 402 under the action of the first sliding device 500. At this time, the first laminator 402 performs preliminary lamination on the cotton stalk fibers and forms a plate body 100. At the same time, the first printing 403 and the second printing 404 at the bottom of the first laminator 402 press the plate body 100, and after the lamination is completed, the electric push rod 504 is controlled to move. The electric push rod 504 drives the plug plate 506 to move through the synchronous plate 505, so that the laminated plate body 100 falls onto the support plate 603;

[0088] At this time, the second sliding device 600 drives the third sliding device 601 and the support plate 603 to move, and the third sliding device 601 drives the support plate 603 to move, and aligns the multiple support plates 603 with each other;

[0089] The fourth sliding device 602 is started, and the fourth sliding device 602 drives the mounting block 700 to move, and the mounting block 700 drives the clamping plate 703 to move. When the clamping plate 703 abuts the third sliding device 601, the mounting block 700 continues to move and pushes the clamping plate 703 through the push plate 705. At this time, the clamping plate 703 moves to one side and extends toward the plate body 100. At the same time, relative sliding occurs between the insertion block 701 and the mounting block 700. When the rotating plate 710 is offset from the mounting block 700 and pops out under the action of the torsion spring 711, the rotating plate 710 The mounting block 700 is pressed against, and the fourth sliding device 602 is moved in the opposite direction. The board body 100 is driven to move to the second laminator 604 through the clamping plate 703. When the board body 100 completely enters the second laminator 604, the support plate 712 presses against the rotating plate 710 to reset it, so that the insert block 701 can enter the mounting block 700 and can be reset by the spring 708. At the same time, the second laminator 604 laminates multiple board bodies 100 to form a composite layered structure to obtain a high-density laminated fiberboard based on cotton stalks.
