[0028] The invention discloses a bamboo-wood composite board production line with a shavings device, which realizes the continuous production of the bamboo-wood composite board.

[0029] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] like Figure 1-Figure 3 As shown, Figure 1 Schematic diagram of the conveying structure of the bamboo-wood composite board production line with shaving equipment provided in this application; Figure 2 for Figure 1 Schematic diagram of the structure of the continuous winder; Figure 3 This is a schematic structural diagram of the laminating device of the bamboo-wood composite board production line with shaving equipment provided in this application.

[0031] The present application provides a bamboo-wood composite board production line with a shavings device, including a core arranging and assembling machine 1 for arranging, assembling and conveying bamboo-wood units, the core arranging and assembling machine 1 having a conveyor belt 101 for conveying bamboo-wood units; a continuous winder 2 mounted above the conveyor belt 101 for continuously laying bamboo curtains on the conveyor belt; a multifunctional paving machine 3 cooperating with the continuous winder 2 to continue laying shavings on the conveyor belt 101 on which the bamboo curtains are laid; a sawing device 4 for sawing the bamboo curtains and shavings laid in layers on the conveyor belt 101 to obtain slabs; and a laminating and forming device for laminating and heating the slabs so that the slabs are bonded together. The laminated bamboo curtains and wood shavings are conveyed by the core assembling machine 1, wherein the bamboo curtains are continuously laid on the conveyor belt 101 by the continuous winder 2, and while the conveyor belt is conveying the bamboo curtains, the wood shavings are laid by the multifunctional laying machine 3, and the bamboo curtains and wood shavings form a stacked bamboo-wood unit, which is sawn and divided by the sawing device 4 to form a slab of stacked bamboo curtains and wood shavings, and the bamboo curtains and wood shavings are bonded to form a bamboo-wood composite board by laminating and heating the slabs, and by the thermosetting resin adhesive pre-coated in the bamboo-wood unit, thereby realizing continuous processing of the bamboo-wood composite board.

[0032] In this embodiment, the shavings are planed wood or wood products in the form of sheets or strips. When paving, the shavings can be evenly scattered and cross-stacked to increase stability.

[0033] In this embodiment, the conveyor belt 101 needs to meet the requirements of conveying and bearing the bamboo curtain and particle board. The conveyor belt 101 can adopt a smooth conveyor belt, a mesh belt, a metal mesh conveyor belt or a metal chain or metal plate conveyor belt to meet the conveying requirements of the bamboo curtain and particle board.

[0034] In a specific embodiment of the present case, the continuous winder 2 includes a wind-up frame 201 mounted across the conveyor belt, and a rotating support roller group 201 provided on the top of the wind-up frame 201; the bamboo curtain is a continuously wound bamboo curtain drum 203, which is rotated by the rotating support roller group to maintain continuous transportation.

[0035] Furthermore, the bamboo curtain reel 23 is a continuous reel formed by a single-layer bamboo curtain, a multi-layer bamboo curtain, a continuous single board or a continuous bamboo-based new material board.

[0036] The bamboo curtain is wound to form a bamboo curtain drum 23. The bamboo curtain is woven from bamboo warp yarn and then wound to form the bamboo curtain drum 23. The bamboo curtain can be woven from a single layer of bamboo to form a single-layer bamboo curtain, or it can be woven from multiple layers of bamboo to form a multi-layer bamboo curtain. The drum can also be wound from a continuous single board, such as a composite board or a bamboo-based new material board.

[0037] The wound bamboo curtain drum 23 can be continuously transported by rotation during the conveying process. The continuous winding machine is provided with a winding frame mounted across the conveyor belt, and the top of the winding frame is provided with an arc-shaped rotating roller support roller group composed of multiple rotating rollers, thereby realizing rotation support during the rotation of the bamboo curtain drum.

[0038] Since the bamboo curtain drum gradually becomes smaller as the output diameter of the bamboo curtain decreases, by adopting a rotating roller support roller group structure, a stable output line speed that is the same as the shaving equipment production line 102 can be achieved, rather than accelerating the rotation speed as the drum diameter becomes smaller, thereby adapting to the rotation and transportation of bamboo curtain drums of different diameters.

[0039] Furthermore, a rotating center roller for rotatably supporting the bamboo curtain drum is provided on the winding frame 21. The rotating center roller is a single roller structure. When the bamboo curtain drum 23 is placed above the rotating support rod group 22, the rotating center roller is inserted into the middle of the bamboo curtain drum from one side of the winding frame, and its position is adjusted as the diameter of the bamboo curtain drum changes, thereby achieving stable support of the bamboo curtain drum by the rotating support roller group and the rotating center roller.

[0040] In a specific embodiment of this case, the multifunctional paving machine 3 includes a wood shavings storage bin and a wood shavings paving channel connected to the storage bin to continuously output wood shavings and evenly distribute them onto the conveyor belt after the bamboo curtain is laid. Wood shavings are wood planks processed by shaving. The wood shavings are spread onto the bamboo curtain on the conveyor belt by the multifunctional paving machine, forming a layered structure of bamboo curtain and wood shavings.

[0041] The multifunctional paving machine 3 is used to lay wood shavings. A storage bin is provided for preloading the shavings into the multifunctional paving machine, and the shavings in the bin are continuously conveyed through a shavings paving channel. The shavings paving channel is adapted to have a certain span in the width direction of the conveyor belt, and has a shavings discharge outlet corresponding to the width direction of the conveyor belt. The shavings discharge channel can be configured as a horizontal shavings conveyor belt and an inclined shavings discharge channel. Multiple sets of roller ratchet structures can be intermittently arranged on the shavings discharge channel to form a hooking and pulling conveying structure for the shavings, arranged in a longitudinal or transverse arrangement.

[0042] In a specific embodiment of this case, the continuous unwinder 2 and the multifunctional paving machine 3 comprise multiple groups arranged along the conveyor belt's conveying direction. Bamboo-wood composite panels can have multiple layers of bamboo curtains and wood shavings, depending on their specifications and thickness. To accommodate the multi-layer structure of bamboo-wood composite panels, the provision of multiple groups of continuous unwinders and multifunctional paving machines allows for the laying of different layers of bamboo curtains and wood shavings when preparing bamboo-wood composite panels of varying specifications, thus meeting the requirements for producing multi-layer bamboo-wood composite panels.

[0043] In a specific embodiment of the present case, the core-distributing and assembling machine 1 further includes a dynamic weighing device 6, which is arranged at the front end of the wood shavings paving channel and dynamically weighs the weight of the paved bamboo curtains and wood shavings. For multi-layer bamboo-wood composite boards, multiple layers of bamboo curtains are staggered between the wood shavings to form a layered structure. The thickness of the formed bamboo-wood composite board can be controlled by the stacking thickness of the bamboo curtains and wood shavings during the paving stage. Since the bamboo curtains and wood shavings are conveyed continuously, a dynamic weighing device 6 is arranged below the conveyor belt of the core-distributing and assembling machine 1 to weigh the paved bamboo curtains and wood shavings during the conveying process, thereby controlling the paving thickness of the continuously laid wood shavings.

[0044] It can be understood that for multiple groups of continuous unwinders 1 and multifunctional paving machines 2, the dynamic weighing device 6 is arranged at the front end of the wood shavings paving channel of the multifunctional paving machine 2, so that after obtaining the weighing data of the dynamic weighing device, the weight of the paved wood shavings can be adjusted immediately. When there are multiple groups of continuous unwinders 1 and multifunctional paving machines 2, the dynamic weighing device is preferably arranged corresponding to the multifunctional paving machine at the rear end of the conveying direction. For example, if there are preferably three groups of continuous unwinders 2 and multifunctional paving machines 3, the dynamic weighing device 6 is preferably arranged corresponding to the second and third groups of multifunctional paving machines in the conveying direction. For multiple groups of continuous unwinders 2 and multifunctional paving machines 3, continuous unwinders are arranged at the front and rear ends of the conveying direction, so that the bamboo curtain covers the bottom and top surfaces to prevent the surface wood shavings from being loose and scattered.

[0045] In a specific embodiment of the present case, it also includes a first control device electrically connected to the dynamic weighing equipment and the multifunctional paving machine. The first control device obtains the weighing data of the dynamic weighing equipment and adjusts the amount of wood shavings paving material of the multifunctional paving machine.

[0046] In a specific embodiment of this case, the laminating and forming apparatus includes a flat-plate pre-pressing machine 5 for compacting the slabs along their thickness, and a hot pressing unit 7 for performing long-term, multi-layer hot pressing on the pre-pressed slabs. Because wood shavings have a loose structure and are relatively thick after being laid down in multiple layers, the sawn slabs are physically laminated by the flat-plate pre-pressing machine 5 to achieve a tighter, more compact structure along their thickness, reducing their thickness. The hot pressing and lamination process is then performed by the multi-layer hot pressing device within the hot pressing unit 7, allowing more slabs to be hot-pressed at once within the unit, improving work efficiency.

[0047] Furthermore, a variable-speed conveyor is provided between the sawing device and the flat-plate pre-pressing machine 5 for variable-speed conveying of the slabs, so as to transport the continuous slabs in sections. Laminating and compacting the slabs requires a certain lamination time, which affects the continuous conveying of the slabs. By providing a variable-speed conveyor for variable-speed conveying between the sawing device and the flat-plate pre-pressing machine, the slabs can be quickly fed into the flat-plate pre-pressing machine for physical lamination after sawing, thereby ensuring the continuity of slab transportation. Preferably, the sawing device is a mobile cross-cutting saw that can move synchronously with the stacked bamboo curtains and particleboards, and during the movement, the mobile cross-cutting saw performs transverse sawing along the width direction, and after cutting is completed, returns to the initial position to continue sawing the next section of the slab.

[0048] Furthermore, the variable-speed conveyor is equipped with a static weighing device for statically weighing the slabs conveyed in sections. After sawing, the slabs are hot-pressed to produce bamboo-wood composite panels. The difference between the weight of the slabs and the weight of the hot-pressed bamboo-wood composite panels can be measured. The static weighing device is used to weigh the slabs accurately.

[0049] Furthermore, the system includes a second control device electrically connected to the static weighing device. The second control device receives static weighing data of the slabs and feeds it back to the slab assembly process of the front-end core assembly machine and the hot pressing process of the hot pressing unit. The second control device obtains static weighing data from the static weighing device. When the static weighing data exceeds a threshold, the static weighing data can be fed back to the slab assembly process according to the static weighing structure to correct the stacking weight of the bamboo curtain and wood shavings. The data is also fed back to the hot pressing unit to adjust the hot pressing parameters to ensure that the weight of the bamboo-wood composite board after hot pressing is within a predetermined range. This achieves dynamic adjustment of the slab weight and makes the quality of the hot-pressed bamboo-wood composite board controllable.

[0050] In a specific embodiment of the present case, a telescopic conveyor 8 is also provided between the flat plate pre-pressing machine 5 and the hot pressing unit 7. The telescopic conveyor 8 has a telescopic table 81 that connects the output end of the flat plate pre-pressing machine 5 and the material input end of the hot pressing unit 7, and moves the pre-pressed slab to a predetermined position for transportation.

[0051] The slab after physical lamination by the flat-plate pre-pressing machine 5 needs to be sent to the hot press bed 71 of the hot press unit 7. Since the hot press bed 71 is recycled in the hot press unit 7, a fixed conveyor belt cannot be set between the flat-plate pre-pressing machine 5 and the hot press unit 7. A telescopic conveyor 8 is set behind the flat-plate pre-pressing machine 5. The telescopic conveyor 8 includes a machine body and a telescopic table 81 arranged on the machine body. When the slab after pre-pressing needs to be transported, the slab output by the flat-plate pre-pressing machine 5 is received by the telescopic table 81. The telescopic table 81 extends to the material input end of the hot press unit 7, and the slab is sent to the hot press bed 71 through the telescopic table, thereby realizing continuous transportation of the slab.

[0052] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
