Description

Technical Field

[0001] The present invention relates to the field of reconstituted plate manufacturing, in particular to a continuous production line and a production method for reconstituted plate. Background Art

[0002] Reconstructed boards (such as reconstructed bamboo, reconstructed wood, etc.) are a high-performance, high-value-added green, low-carbon and environmentally friendly composite material made of bamboo or wood through directional reconstructed technology and compounded with glue. Due to its excellent physical and mechanical properties and environmental protection characteristics, it is widely used in construction, furniture, landscaping, transportation and other fields.

[0003] The current reconstituted board production process includes debonding, gluing, drying, paving, assembly, and pressing. Equipment is distributed in a scattered manner, sometimes requiring manual transport. Companies primarily use an intermittent cage gluing process, where veneers are placed in a specialized cage and then placed in a gluing tank for a period of time before being removed. Excess glue is then drained and allowed to equilibrate for four to seven days before drying, resulting in a long production cycle.

[0004] Furthermore, poor integration between process steps can lead to adhesive dripping and contamination during transfer, or changes in the adhesive layer (e.g., partial pre-curing of the adhesive), impacting process stability and product quality. These issues hinder further improvements in the quality of reconstituted board products and the reduction of production costs.

[0005] Therefore, it is urgent to develop new, integrated production technologies to improve the production efficiency and green level of reconstituted boards. Summary of the Invention

[0074] The preparation process of bamboo strips is as follows:

[0075] The bamboo tube is split by a bamboo splitting machine to obtain bamboo strips; the bamboo strips are graded according to their location and wall thickness; the same bamboo strip is divided into three sections along its length: upper section, middle section, and lower section; the sections are secondary graded according to their wall thickness; the graded bamboo strips are stacked, ensuring that the green side and yellow side of all bamboo strips face the same direction, and the larger and smaller diameter ends of the bamboo strips face the same direction; in subsequent processes, the bamboo strips or bamboo strip sections of the same grade are continuously processed;

[0078] S2, placing the stacked veneers on the feeding device 1; the veneers output by the feeding device 1 are sent to the decomposition device 2 for processing into fiberized veneers;

[0079] S3, the fiberized veneer is sent to the dipping device 3 via the conveying device 9, and glue is applied on the fiberized veneer to obtain a dipping product;

[0080] S4, the impregnated product is subjected to debinding in the debinding device 4 to remove excess glue to obtain a debinding product;

This integrated design ensures the quality stability of the reconstituted board, improves production efficiency, and reduces manual intervention and waiting time between processes.

[0086] (2) The alternating buffer mechanism of the rolling mechanism and the first cutting mechanism in the whole-sheet veneer equipment effectively solves the speed matching problem between the continuity of the sewing / weaving process and the downstream cutting device or the subsequent hot pressing process, so that the downstream equipment can run more smoothly and reduce the downtime caused by upstream feeding speed fluctuations or downstream processing speed limitations, thereby improving the efficiency and continuity of the entire production line.

[0087] (3) The debinding device in the continuous production line of reconstituted board of the present invention realizes contact-type and gentle debinding through adsorption force, absorbs and collects excess glue on the surface of the impregnated product, and effectively avoids material damage, thereby ensuring the uniformity of debinding and the stability of quality of the impregnated product.

[0128] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described with reference to the accompanying drawings. Figures 1 to 31The technical solutions of the present invention are clearly and completely described in detail with reference to the accompanying drawings and specific embodiments.

[0129] The present application provides a continuous production line for reconstituted sheet materials (hereinafter referred to as the "production line"), such as Figure 1 As shown in FIG, the production line is arranged in an L shape. The production line includes a feeding device 1 for placing veneers and feeding them to a debonding device 2; along the horizontal direction of the feeding device 1, there are arranged in sequence a debonding device 2 for debonding the veneers, a dipping device 3 for dipping the fiberized veneers into glue, and a debonding device 4 for discharging excess glue from the dipping product. Figure 2 Along the vertical direction of the conveying device 9 are arranged sequentially with a drying device 5, a whole sheet of single board equipment 6, a cutting device 7 and a forming device 8, as shown Figure 3 The debonding device 2 and the impregnation device 3, as well as the debonding device 4 and the drying device 5 are connected via a conveying device 9.

[0130] Specifically, if Figure 6 and Figure 7 As shown, the feeding device 1 includes a feeder frame 11, on which a main feeder belt conveyor 12 is mounted. The main feeder belt conveyor 12 includes a first conveyor bracket 121 fixed to the feeder frame 11, rollers disposed at both ends of the first conveyor bracket 121, and a first conveyor belt 122 mounted on the rollers. The rollers are driven by a motor to rotate, thereby driving the first conveyor belt. An operator places a single board on the first conveyor belt 122 of the main feeder belt conveyor 12, which then drives the single board to the defragmenting device 2. Furthermore, the feeding device 1 includes side feeder belt conveyors 13 mounted on the feeder frame 11 and located on both sides of the main feeder belt conveyor 12. The side feeder belt conveyors 13 include a second conveyor bracket 131 fixed to the feeder frame 11, rollers disposed at both ends of the second conveyor bracket 131, and a second conveyor belt 132 mounted on the rollers. The discharging end of the side feeding belt conveyor 13 faces the main feeding belt conveyor 12. By controlling the discharge sequence and the rotation speed of the second conveyor belt 132, the two side feeding belt conveyors 13 alternately feed the main feeding belt conveyor 12.

[0131] Furthermore, the first conveyor bracket 121 includes a vertical portion 121a and an inclined portion 121b. The bottom end of the vertical portion 121a is fixedly connected to the feeder frame 11, the fixed end of the inclined portion 121b is located at the top of the inclined portion 121a, and the free end of the inclined portion 121b faces the second conveyor belt 132. A guide groove is formed between the first conveyor brackets 121 on both sides, ensuring that the veneers are conveyed smoothly on the feeder 1, providing quality assurance for subsequent debonding, dipping, and debinding.

[0132] Furthermore, the feeding device 1 includes a storage frame 14 positioned above the side-feeding belt conveyor 13, within which single boards are stacked. Second conveyor brackets 131 on either side of the side-feeding belt conveyor 13 are fixedly provided with support plates 15, which extend upward perpendicularly to the horizontal plane of the second conveyor belt 132. The support plates 15 support the storage frame 14, and the distance between the bottom end of the storage frame 14 and the second conveyor belt 132 is greater than the thickness of one single board and less than the thickness of two single boards. When the side-feeding belt conveyor 13 is in operation, the single boards at the bottom of the storage frame 14 are pulled out via the second conveyor belt 132 and brought onto the first conveyor belt 122. The second conveyor belt 132 may be provided with push plates along the conveying direction to push the single boards out.

[0133] Taking into account that when the reconstructed board is made of reconstructed bamboo material, the diameter of the bamboo along the growth direction is different, and the prepared bamboo pieces have large width edges and small width edges, the large width edges and the small width edges are ensured to be in the same direction when stacking the materials. During the use of the feeding device 1, the large width edge of the veneer in one storage frame 14 faces forward, and the small width edge of the veneer in the other storage frame 14 faces forward. The side feeding belt conveyor 13 alternately feeds the main feeding belt conveyor 12. Through the above-mentioned alternating feeding method, the dried products entering the integrated veneer equipment 6 are complementary in the width direction, thereby ensuring that the overall width of the woven continuous curtain is uniform.

[0134] In actual application, in combination with some of the above embodiments, the debonding device 2, the glue dipping device 3, and the glue removal device 4 all adopt a double-roller structure.

[0135] The debonding device 2 is provided with a set of debonding rollers in parallel, and each set of debonding rollers includes an upper debonding roller and a lower debonding roller corresponding to each other, both of which are provided with a tooth structure on their surfaces. The debonding device 2 is also provided with a driving mechanism for driving the upper debonding roller and the lower debonding roller to rotate. During operation, the upper debonding roller and the lower debonding roller cooperate with each other to promote the separation and extension of the fibers by applying a rolling action to the sheet material and supplemented by a kneading effect, thereby making the sheet material expand uniformly in the lateral direction. The debonding device 2 is a conventional setting of the prior art and is not within the scope of protection of the present invention. The embodiments of the present invention will not be described in detail.

[0136] The drying device 5 includes a drying box 51 and a drying conveying mechanism 52. The drying box 51 is provided with a drying feed port and a drying discharge port at opposite ends. The feed end of the drying conveying mechanism 52 extends out of the drying feed port, and the discharge end of the drying conveying mechanism 52 extends out of the drying discharge port. The discharge end of the conveying device 9 between the debinding device 4 and the drying device 5 is laterally docked with the feed end of the drying conveying mechanism 52. The veneer is conveyed from the feeding device 1 to the conveying device 9 along the length direction of the plate, and is conveyed along the width direction of the plate on the drying conveying mechanism 52. A hot air mechanism is provided inside the drying box 51 for blowing hot air to dry the debinding product. Specifically, the hot air mechanism includes a heater and a plurality of fans, and the fans are arranged along the conveying direction. The drying conveying mechanism 52 has the same conveying structure as the conveying device 9, and the motor drives the roller to rotate and then drives the belt to operate. To keep the debinding product delivered from conveyor 9 moving along the width of the sheet material, the belt of drying conveyor 52 is provided with grooves or protrusions whose edges correspond to the shape of the sheet material. Furthermore, ventilation holes are provided on the belt within the grooves or protrusions to ensure uniform drying of the debinding product.

[0137] like Figure 3 As shown, the sheeting equipment 6 includes an intermediate conveyor 61, a sewing mechanism 62, and a rolling mechanism 63. Both the intermediate conveyor 61 and the sewing mechanism 62 are securely mounted on the equipment frame to ensure operational stability. The intermediate conveyor 61 is positioned vertically below the discharge end of the drying conveyor 52 to receive the dried product after drying. The sewing mechanism 62 is fixedly mounted on the frame and precisely positioned above the intermediate conveyor 61. Its function is to sew the edges of the individual dried products conveyed by the intermediate conveyor 61 together to form a continuous curtain. The sewing mechanism 62 efficiently stitches and weaves discrete individual dried products into a continuous curtain-like material, providing a continuous flow of raw materials for subsequent processes. The rolling mechanism 63 is located outside the discharge end of the intermediate conveyor 61 to receive and wind up the woven continuous curtain. The core feature of this mechanism is the inclusion of two alternating receiving trays 631. The first cutting mechanism 64 is positioned between the discharge end of the intermediate conveyor 61 and the rolling mechanism 63. A dried product leveling mechanism is provided before the sewing mechanism 62 so that the dried products are evenly spaced.

[0138] The workflow and alternating mechanism of the sheet-forming veneer device 6: The sewing mechanism 62 continuously stitches the individual sheets into a continuous curtain. The continuous curtain is then fed to the winding mechanism 63. The two receiving trays 631 operate in alternating modes: one receiving tray 631 is in the rewinding state, continuously winding the continuous curtain woven and output by the sewing mechanism 62; the other receiving tray 631 is in the supplying state, releasing the already wound continuous curtain to the downstream slicing device 7. When the rewinding receiving tray 631 (the one closest to the sewing mechanism 62) reaches full material, a switching process is triggered. The first cutting mechanism 64 activates, severing the continuous curtain woven and output by the sewing mechanism 62. The rewinding operation switches from the full receiving tray 631 to the other ready (usually empty or partially full) receiving tray 631, which then enters the rewinding state. Simultaneously, the previously full receiving tray 631 switches to the supplying state and begins feeding the downstream slicing device 7.

[0139] The alternating buffer mechanism of the sheeting unit 6 effectively addresses the speed matching issue between the relatively fast and continuous sewing / weaving process and the slower or intermittent operation of the downstream sheeting unit 7 or subsequent hot press forming process. This provides buffer time for downstream processes (particularly hot press forming), enabling smoother operation of downstream equipment and reducing downtime caused by upstream feed rate fluctuations or downstream processing speed limitations, significantly improving the efficiency and continuity of the entire production line.

[0140] The transition conveyor 61 is configured to have a speed lower than that of the drying conveyor 52. The vertical height difference and speed difference between the transition conveyor 61 and the drying conveyor 52 are suitable for forming an overlapping arrangement of the dried products on the transition conveyor 61. Figure 4 The overlap distance between the dried products is 2-5 mm (the overlap distance of the reconstituted boards in the same batch is consistent).

[0141] like Figure 3 As shown, the cutting device 7 includes a front conveying mechanism 71 and a rear conveying mechanism 72 arranged in sequence in the conveying direction of the continuous curtain. A second cutting mechanism 73 is provided between the front conveying mechanism 71 and the rear conveying mechanism 72 for cutting the continuous curtain into curtain sheets.

[0142] The structures of the single board unit 6 and the slicing device 7 are prior art and will not be described in detail in this embodiment. For details, reference may be made to the relevant technology disclosed in the Chinese patent publication number CN 120206594 A.

[0143] The forming device 8 includes a forming frame 81, on which is disposed a transfer mechanism 82. One end of the transfer mechanism 82 is located below the rear-end conveyor mechanism 72. A lower pressing plate 83 is slidably disposed on the transfer mechanism 82. The lower pressing plate 83 receives the curtain pieces transmitted from the discharge end of the rear-end conveyor mechanism 72. Due to the height difference between the transfer mechanism 82 and the rear-end conveyor mechanism 72, multiple curtain pieces are stacked and assembled on the lower pressing plate 83. A hot pressing bracket 84 is fixedly disposed in the middle of the forming frame 81. The hot pressing bracket 84 is provided with an upper pressing plate lifting drive mechanism 85. The output end of the upper pressing plate lifting drive mechanism 85 is provided with an upper pressing plate 86. The lower pressing plate 83 and the upper pressing plate 86 each have a built-in heater, which is a metal resistance wire.

[0144] A first position sensor 87 is provided at the end of the forming frame 81 corresponding to the rear conveyor mechanism 72, a second position sensor 88 is provided at the position of the forming frame 81 corresponding to the hot pressing bracket 84, and a third position sensor 89 is provided at the end of the forming frame 81 away from the rear conveyor mechanism 72. These position sensors detect the position of the lower platen 83 and transmit signals to the control system, thereby controlling the operation or stop of the transfer mechanism 82. The position sensors are preferably photoelectric switches that can detect the position and clearance of the lower platen.

[0145] In the initial state, the lower pressing plate 83 is located at one end of the transfer mechanism below the rear end conveying mechanism 72, as shown in FIG. Figure 8 As shown, the first position sensor 87 detects that the lower pressing plate 83 is in place, and the lower pressing plate 83 receives the curtain pieces transmitted from the discharge end of the rear end conveying mechanism 72 and stacks the blanks on the lower pressing plate 83, as shown in FIG. Figure 5 When the number of curtain pieces stacked reaches the designed number, the transfer mechanism 82 drives the lower pressing plate 83 to move horizontally toward the upper pressing plate 86. When the second position sensor 88 detects that the lower pressing plate 83 is in place, the transfer mechanism 82 stops running, and the upper pressing plate lifting drive mechanism 85 drives the upper pressing plate 86 to descend. The upper pressing plate 86 and the lower pressing plate 83 heat and press the stacked curtain pieces to form. Figure 9 After heating and pressurizing for a preset time, the upper platen lift drive mechanism 85 drives the upper platen 86 upward, and the transfer mechanism 82 operates to drive the lower platen 83 forward. When the third position sensor 89 detects that the lower platen 83 is in position, the transfer mechanism 82 stops, and the operator removes the formed reconstituted sheet from the lower platen 83, completing the reconstituted sheet preparation process. The transfer mechanism 82 drives the lower platen 83 back to one end of the transfer mechanism located below the rear conveyor mechanism 72 for the next material receiving process.

[0146] Among them, the upper pressure plate lifting drive mechanism 85 includes but is not limited to linear drive elements such as air cylinders, oil cylinders, and electric push rods, and the transfer mechanism 82 includes but is not limited to linear drive elements such as screw slide structures, gear rack transmission structures, and synchronous belt structures, and only needs to be able to provide linear driving force.

[0147] The conveyor 9 can be constructed using multiple sets of conveyor rollers, driven by a conveyor frame motor and synchronously rotated via a chain drive system to ensure smooth transport of the sheet materials. The conveyor 9 can also be a belt conveyor. The upper surface height of the conveying plane of the conveyor 9 is strictly aligned with the discharge port of the debonding device 2 and the feed port of the impregnation device 3. The upper surface height of the conveying plane of the conveyor 9 is also strictly aligned with the discharge port of the debonding device 4 and the feed port of the drying device 5. As the key transmission unit connecting the debonding device 2 with the impregnation device 3, and the debonding device 4 with the drying device 5, the conveyor 9 enables continuous conveying of the sheet materials, buffering adjustment, and speed matching. By dynamically adjusting the transmission rate, the conveyor 9 effectively coordinates the production rhythm differences between the upstream debonding device 2 and the downstream impregnation device 3, and between the debonding device 4 and the drying device 5. Furthermore, the conveyor 9 can provide short pauses during the conveying process to facilitate online quality inspection of the fiberized veneer and debonding products, and to promptly remove unqualified products.

[0148] The fiberized veneer is glued in the glue impregnation device 3, and the glue (such as phenolic resin, etc.) is introduced into the decomposed wood or bamboo units through penetration, so that it is combined with the fibers, thereby enhancing the structural strength and stability of the board.

[0149] The structure of the dipping device 3 is as follows Figures 10 to 24 The dipping device 3 comprises a dipping frame 31 , a glue tank 32 , a dipping roller assembly 33 and a dipping roller rotation drive mechanism 34 .

[0150] The dipping machine frame 31 provides a solid foundation support for the glue pool 32, the dipping roller assembly 33 and the dipping roller rotation drive mechanism 34, ensuring the rigidity and stability of the equipment during the extrusion process.

[0151] The glue tank 32 is mounted on the dipping machine frame 31, and the glue used for dipping is stored in the tank. Specifically, the tank 32 comprises a box structure with an upper opening and a closed bottom and perimeter, formed by side panels 321 and a bottom panel 322. The bottom panel 322 is provided with a glue inlet pipe 323 and a slag discharge pipe 324. The glue inlet pipe 323 is connected to the glue supply mechanism 37, and the slag discharge pipe 324 is connected to the slag discharge mechanism 38. Roller sealing plates 325 are provided on opposite sides of the side panels 321 along the sheet material conveying direction. The roller sealing plates 325 have through-holes 325a, which provide a passage for the rotating shaft to pass through. A ring 325b is provided on the side of the through-hole 325a, and a sealing ring is disposed within the ring 325b. The ring 325b provides a chamber for accommodating and securing the sealing ring. The provision of the sealing ring prevents glue leakage at the connection point. The lower dipping roller shaft 336 passes through the through hole 325a of the roller sealing plate 325 and is sealed with the sealing ring in the ring sleeve 325b.

[0152] The sealing ring tightly wraps the rotating lower dipping roller shaft 336, forming an effective dynamic sealing barrier between the shaft and the ring sleeve / roller sealing plate. The structural combination design prevents the glue in the glue pool from leaking outward along the gap between the shaft and the through hole, ensuring the stability of the glue composition and uniform dipping depth.

[0153] The glue supply mechanism 37 includes a glue liquid tank 371 and a power pump 372 connected by a pipeline. The output port of the power pump 372 is connected to the glue inlet pipe 323 through a pipeline.

[0154] The slag discharge mechanism 38 comprises a slag receiving hopper 381 and a slag discharge guide cylinder 382, ​​located below the slag discharge liquid pipe 324. One end of the slag discharge guide cylinder 382 is located within the slag receiving hopper 381 and has a filter hole. A propeller 383 is installed within the slag discharge guide cylinder 382, ​​and a rotational drive motor is installed at the end of the propeller 383. A downward-facing slag discharge port 384 is defined in the middle of the slag discharge guide cylinder 382. The slag receiving hopper 381 receives the residue and waste rubber discharged from the slag discharge liquid pipe 324. The waste rubber is discharged through the filter hole, and the residue is driven by the propeller 383 and discharged from the slag discharge port 384.

[0155] At least three dipping roller assemblies 33 are arranged on the dipping machine frame 31 in a distributed manner along the conveying direction of the fiberized veneer. The dipping roller assemblies 33 are located in the glue tank 32 and are used to squeeze and dip the fiberized veneer. The dipping roller assemblies 33 include an upper dipping roller 331 and a lower dipping roller 332, positioned in a corresponding upper and lower position. The fiberized veneer passes between the upper and lower dipping rollers 331 and 332 for squeeze dipping.

[0156] The dipping roller assembly 33 also includes: a first frame 333, including a first side plate 333a and a second side plate 333b fixed on the dipping machine frame 31; two first slide plates 334 are provided, which are respectively connected to the first side plate 333a and the second side plate 333b for sliding up and down; an upper dipping roller shaft 335, whose two ends are respectively connected to the first slide plates 334 on the left and right sides through bearings; the upper dipping roller 331 is coaxially fixed on the upper dipping roller shaft 335; the lower dipping roller shaft 336, whose two ends are respectively connected to the first side plate 333a and the second side plate 333b through bearings; the lower dipping roller 332 is coaxially fixed on the lower dipping roller shaft 336; a first gear plate group 337, including a coaxial fixed The first upper gear plate 337a is on the upper dipping roller shaft 335 and located on the outside of the first slide 334, and the first lower gear plate 337b is coaxially fixed on the lower dipping roller shaft 336 and engaged with the first upper gear plate 337a; the first lifting drive assembly 338 is arranged on the first frame 333 and connected to the first slide 334; the first lifting drive assembly 338 drives the first slide 334 to move up and down, thereby moving the upper dipping roller 331 toward or away from the lower dipping roller 332. The extrusion gap formed by the upper and lower dipping rollers corresponding to each other exerts controllable pressure on the fiberized veneer, which not only promotes the penetration of the glue, but also squeezes out the air inside the fiberized veneer, avoiding the residual bubbles and causing uneven dipping.

[0157] The first upper gear plate 337a is fixed to the upper glue roller shaft 335, and the first lower gear plate 337b is fixed to the lower glue roller shaft 336. The two gear plates are always meshed. Regardless of the height of the upper glue roller 331 (that is, regardless of the roller gap), this meshing pair of gear plates ensures that the upper and lower glue rollers 331 and 332 rotate in opposite directions at the same linear speed (rotational speed). When the fiberized veneer is clamped between the upper and lower rollers for conveyance, inconsistent speeds can cause the material to stretch, wrinkle, or even tear. Forced synchronization completely eliminates this risk. Speed ​​synchronization ensures consistent traction and impregnation of the material in the roller gap, resulting in uniform glue impregnation. It is only necessary to drive one of the dipping roller shafts (such as the lower dipping roller shaft 336) to drive the other dipping roller shaft (the upper dipping roller shaft 335) to rotate synchronously through gear engagement. There is no need to configure a complex floating drive mechanism (such as a universal coupling, a transmission belt tensioning adjustment mechanism, etc.) for the upper roller separately, which simplifies the drive system design and cost.

[0158] The linear drive source of the first lift drive assembly 338 and the second lift drive assembly 428 includes, but is not limited to, linear drive elements such as air cylinders, oil cylinders, and electric push rods, and only needs to be able to provide linear driving force. The output end of the linear drive source is connected to the slide to transmit the force. In some specific embodiments, the first frame 333 also includes an upper cross plate 333c, the ends of which are respectively fixed to the top of the first side plate 333a and the top of the second side plate 333b. The specific component structure of the first lift drive assembly 338 is described in detail below.

[0159] The first lift drive assembly 338 is a linked worm gear elevator, the output of which is fixedly connected to the first slide 334. The worm gear elevator also incorporates a self-locking mechanism to prevent the pressure roller from experiencing height fluctuations during operation, thereby affecting pressure changes. Both the upper and lower positions of the first slide 334 are equipped with limit switches to prevent the pressure roller from exceeding its operating stroke and potentially damaging the equipment. This worm gear elevator is conventional technology and will not be further described in detail in the present embodiment.

[0160] The sturdy frame, slide guides, and bearing supports provide the necessary rigidity, stability, and reliability for the entire assembly's operation (especially lifting and rotation). The use of bearings ensures smooth, low-friction rotation of the upper and lower roller shafts, withstanding radial loads (primarily material pressure and gear meshing forces) while allowing a certain degree of axial float or positioning. This is the foundation for long-term, stable operation of the equipment.

[0161] The dipping roller rotation drive mechanism 34 includes a rotation drive assembly and a rotation transmission assembly disposed on the dipping machine frame 31. The rotation drive assembly is used to provide rotational driving force to the rotation transmission assembly. The rotation drive assembly is a device capable of outputting rotation, such as an electric motor, an engine, a hydraulic motor, or a combination of one of these and a speed reducer.

[0162] The rotary drive assembly of the embodiment of the present invention comprises a servo motor 341 and a speed reducer 342 connected to the servo motor 341 via a belt. The rotary transmission assembly connects the rotary drive assembly and the dipping roller assembly 33. The rotary transmission assembly is a belt drive or chain gear drive assembly, connected to the speed reducer 342 and in transmission connection with the lower dipping roller shaft 336.

[0163] The rotary transmission assembly of this embodiment of the present invention includes a driving gear 343 disposed at the output end of a speed reducer 342; the driving gear 343 directly meshes with the first lower gear plates 337b of two adjacent sets of dipping roller assemblies 33; and a first driven wheel 344 and a second driven wheel 345 disposed at the ends of the lower dipping roller shafts 336 and located outside the first lower gear plates 337b. Between dipping roller assemblies 33 not directly meshed with the driving gear 343, interlocking transmission is achieved via the first driven wheel 344, the second driven wheel 345 at the ends of the lower dipping roller shafts 336 of the adjacent assemblies, and a transmission belt 346 wrapped around them.

[0164] In the embodiment of the present invention, Figures 13 to 18 As shown, the first driven wheel 344 and the second driven wheel 345 are sprockets, and the transmission belt 346 is a chain that matches the first and second driven wheels 344 and 345. It is suitable for high-torque scenarios and matches the sprockets. Five groups of dipping roller assemblies 33 are arranged from front to back. The driving gear 343 directly meshes with the first lower gear plate 337b of the third and fourth groups of dipping roller assemblies 33, respectively. The dipping roller assemblies 33 not directly meshed with the driving gear 343 (between the first and second groups of dipping roller assemblies 33, between the second and third groups of dipping roller assemblies 33, and between the fourth and fifth groups of dipping roller assemblies 33) are linked by the first driven wheel 344, the second driven wheel 345, and the transmission belt 346.

[0165] The first driven wheel 344 and the second driven wheel 345 can be synchronous pulleys, and the transmission belt 346 is a synchronous belt that matches the first driven wheel 344 and the second driven wheel 345, which is suitable for scenes requiring noise reduction and anti-slip, and matches the synchronous pulleys.

[0166] The driving gear 343 directly drives two sets of adjacent dipping roller assemblies 33 to form the main transmission core, ensuring large torque output and avoiding single-point drive overload; the driving gear 343 is directly engaged with the first lower gear plate 337b to provide a reference speed, and the transmission belt linkage group follows synchronously to avoid speed deviation of the multi-roller group caused by an overly long transmission chain.

[0167] The driving gear 343 drives the two sets of pressure rollers in the middle position, so that the power input is located in the middle of the system, reducing the difference in the length of the transmission chains on both sides and reducing the vibration caused by uneven torque transmission. The intermediate drive mode disperses the load on the transmission belt and avoids the problem of transmission belt wear caused by the excessively long transmission path of the end pressure roller groups. In addition, the first lower gear plate 337b, the first driven wheel 344, and the second driven wheel 345 are coaxially fixed to the end of the lower dipping roller shaft 336, eliminating the need for an additional drive shaft, compressing the lateral installation space, and being suitable for compact equipment. The rotary transmission assembly adopts a hybrid drive mode of "direct engagement-graded transmission belt drive", which achieves efficient power distribution while simplifying the structure.

[0168] At least three dipping roller assemblies 33, positioned sequentially along the conveying direction, perform multiple, continuous extrusion and dipping operations on the fiberized veneer, ensuring that the adhesive fully and evenly penetrates the fiberized veneer's internal structure. A portion of the upper dipping roller 331 and the entire lower dipping roller 332 are positioned within the adhesive in the adhesive pool 32. The fiberized veneer passes between the upper and lower dipping rollers 331 and 332, achieving extrusion and dipping, ensuring that the fiberized veneer remains in contact with the adhesive throughout the dipping process.

[0169] The dipping device 3 also includes a feed bracket 35 and a discharge bracket 36 for supporting the board materials. The feed bracket 35 and the discharge bracket 36 are respectively arranged at opposite ends of the dipping machine frame 31 and are flush with the position between the upper dipping roller 331 and the lower dipping roller 332. The free end of the feed bracket 35 is docked with the discharge end of the conveyor 9 to guide the fiberized veneer accurately into the roller gap. Its bearing surface forms a smooth transition with the roller gap to prevent the fiberized veneer from getting stuck. The free end of the discharge bracket 36 is docked with the feed port of the degumming device 4, facing between the upper degumming roller 421 and the lower degumming roller 422, to receive the board materials that have been dipped. Its horizontal extension length needs to take into account the sagging characteristics of the material. The feed bracket 35 and the discharge bracket 36 together form a continuous support surface to prevent the board materials from warping and deformation and maintain the flatness of the board materials during the dipping process. The height of the fixed end of the discharge bracket 36 is lower than the height of the free end. During the process of conveying the impregnated product to the glue discharge device 4 , part of the glue liquid can flow back to the glue pool 32 along the discharge bracket 36 , so as to avoid excess glue liquid being brought into the glue discharge device 4 and causing glue liquid waste.

[0170] The dipping device 3 provided in the embodiment of the present invention is suitable for industrial dipping equipment that requires precise control of dipping process parameters (such as pressure and roller gap) and ensures synchronization of material transportation.

[0171] The structure of the debinding device 4 is as follows: Figures 25 to 26 The debonding device 4 includes a debonding frame 41, a debonding roller assembly 42, and a debonding roller rotation drive mechanism 43. The debonding frame 41 provides a solid foundation for the debonding roller assembly 42 and the debonding roller rotation drive mechanism 43, ensuring the rigidity and stability of the device during the extrusion process.

[0172] At least two debonding roller assemblies 42 are arranged on the debonding frame 41 in a distributed manner along the conveying direction of the dipped product. These debonding roller assemblies 42 are used to remove excess glue from the dipped product. The debonding roller assemblies 42 include an upper debonding roller 421 and a lower debonding roller 422, positioned correspondingly above and below each other. The dipped product passes between the upper and lower debonding rollers 421 and 422.

[0173] The upper de-glue roller 421 and the lower de-glue roller 422 squeeze the dipped product to remove the glue. The squeeze-type de-glue structure is consistent with the structure of the dipped roller assembly 33. In addition, the upper de-glue roller 421 and the lower de-glue roller 422 can also use negative pressure to remove the glue from the dipped product. Specifically, the negative pressure de-glue structure is as follows:

[0174] like Figures 27 to 31 As shown, the glue removal roller assembly 42 further includes a second frame 423 , a second slide plate 424 , an upper glue removal roller shaft 425 , a lower glue removal roller shaft 426 , a second gear plate assembly 427 and a second lifting drive assembly 428 .

[0175] The second frame 423 includes a third side plate 423a and a fourth side plate 423b that are oppositely positioned and fixed to the debonding frame 41, and are used to support the second slide plate 424, the upper debonding roller shaft 425, and the lower debonding roller shaft 426. Two second slide plates 424 are provided, and are slidably connected to the third side plate 423a and the fourth side plate 423b respectively.

[0176] The upper and lower de-glue roller shafts 425 and 426 are hollow structures. A first air intake port 425a is provided at one or both ends of the upper de-glue roller shaft 425, while a second air intake port 426a is provided at one or both ends of the lower de-glue roller shaft 426. The first and second air intake ports 425a and 426a are connected to an external air extraction device. A first notch 425b is defined in the middle of the upper de-glue roller shaft 425, communicating with the first air intake port 425a. A second notch 426b is defined in the middle of the lower de-glue roller shaft 426, communicating with the second air intake port 426a. The first and second notches 425b and 426b are positioned opposite each other. Both ends of the upper de-glue roller shaft 425 are fixedly connected to the second slide plate 424, while both ends of the lower de-glue roller shaft 426 are fixed to the third and fourth side plates 423a and 423b, respectively. The second gear plate assembly 427 includes an upper gear end cap 427a fixedly mounted on one end face of the upper de-glue roller 421 and a lower gear end cap 427b fixedly mounted on one end face of the lower de-glue roller 422. The upper gear end cap 427a meshes with the lower gear end cap 427b. A second lifting drive assembly 428 is mounted on the second frame 423 and connected to the second slide 424. The second lifting drive assembly 428 drives the second slide 424 up and down, thereby moving the upper de-glue roller 421 toward or away from the lower de-glue roller 422. The upper and lower de-glue rollers, positioned correspondingly above and below each other, form a precise gap, effectively removing excess glue while preventing damage to the dipping product due to excessive squeezing or excessive glue loss that could affect bonding strength.

[0177] The upper de-glue roller 421 is a solid cylinder, coaxially mounted on the upper de-glue roller shaft 425 and rotating relative thereto. The sidewall of the upper de-glue roller 421 is provided with first through-holes 421a arranged in a circumferential and axial array. When the upper de-glue roller 421 rotates, the first notches 425b communicate with the corresponding first through-holes 421a. The lower de-glue roller 422 is a solid cylinder, coaxially mounted on the lower de-glue roller shaft 426 and rotating relative thereto. The sidewall of the lower de-glue roller 422 is provided with second through-holes 422a arranged in a circumferential and axial array. When the lower de-glue roller 422 rotates, the second notches 426b communicate with the corresponding second through-holes 422a.

[0178] The upper de-glue roller 421 has a central, axial through-hole. The upper de-glue roller shaft 425 passes through this through-hole, with the outer wall of the shaft 425 conforming to the inner wall of the upper de-glue roller 421. The lower de-glue roller 422 has a central, axial through-hole. The lower de-glue roller shaft 426 passes through this through-hole, with the outer wall of the shaft 426 conforming to the inner wall of the lower de-glue roller 422. Both the upper de-glue roller shaft 425 and the lower de-glue roller shaft 426 are hollow, serving as both a channel for transferring glue and the central axis of rotation for the upper and lower de-glue rollers 421 and 422.

[0179] The other end face of the upper rubber removal roller 421 opposite to the upper gear end cover 427a is fixedly connected to a roller end cover. The other end face of the lower rubber removal roller 422 opposite to the lower gear end cover 427b is fixedly connected to a sprocket end cover for connecting to the external second rotation transmission assembly 240.

[0180] The upper gear end cap 427a and the roller end cap rotate relative to the upper rubber roller shaft 425, while the lower gear end cap 427b and the sprocket end cap rotate relative to the lower rubber roller shaft 426. Specifically, the upper gear end cap 427a and the roller end cap are each equipped with bearings, with the upper rubber roller shaft 425 passing through two bearings. The lower gear end cap 427b and the sprocket end cap are each equipped with bearings, with the lower rubber roller shaft 426 passing through two bearings.

[0181] Roller seals are installed on the outer wall of the upper de-bonding roller shaft 425, between the upper gear end cover 427a and the upper de-bonding roller 421, and between the roller end cover and the upper de-bonding roller 421. Roller seals are installed on the outer wall of the lower de-bonding roller shaft 426, between the lower gear end cover 427b and the lower de-bonding roller 422, and between the sprocket end cover and the lower de-bonding roller 422. The roller seals improve the sealing of the assembly connection and provide effective suction force for the upper de-bonding roller 421 and the lower de-bonding roller 422.

[0182] The meshing transmission between the upper gear end cover 427a and the lower gear end cover 427b also has the same technical effect as the meshing transmission between the first upper gear plate 337a and the first lower gear plate 337b, which will not be repeated here.

[0183] The sidewall of the upper debonding roller 421 is provided with a circumferential and axial array of first through holes 421a, while the lower debonding roller 422 is provided with a plurality of second through holes 422a. The diameters of the first and second through holes 421a, 422a can be tailored to the design requirements of the dipping product. It is understood that when the diameters of the first and second through holes 421a, 422a are larger, the adsorption force at the locations where the diameters of the first and second through holes 421a, 422a are located is greater; when the diameters of the first and second through holes 421a, 422a are smaller, the adsorption force at the locations where the diameters of the first and second through holes 421a, 422a are located is less.

[0184] The upper debonding roller 421 has a set of axially arranged first through holes 421a forming a row. Similarly, the lower debonding roller 422 has a set of axially arranged second through holes 422a forming a row. The distance between adjacent rows of first through holes 421a and / or second through holes 422a can be designed based on the design requirements of the dipping product. It is understood that when the distance between adjacent rows of first through holes 421a and / or second through holes 422a is greater, the suction force of the debonding roller assembly is weaker; when the distance between adjacent rows of first through holes 421a and / or second through holes 422a is smaller, the suction force of the debonding roller assembly is stronger.

[0185] The upper gear end cap 427a and the roller end cap rotate relative to the upper debonding roller shaft 425, while the lower gear end cap 427b and the sprocket end cap rotate relative to the lower debonding roller shaft 426. Specifically, the upper gear end cap 427a and the roller end cap are each equipped with bearings, with the upper debonding roller shaft 425 passing through two bearings. The lower gear end cap 427b and the sprocket end cap are each equipped with bearings, with the lower debonding roller shaft 426 passing through two bearings. The first notch 425b of the upper debonding roller shaft 425 faces downward, while the second notch 426b of the lower debonding roller shaft 426 faces upward. During roller rotation, the two through-holes remain opposite each other, facing the dipped product. As the upper and lower debonding rollers 421 and 422 rotate, portions of the first through-hole 421a always align with the first notch 425b, and the second through-hole 422a always align with the second notch 426b, ensuring a continuous debonding process. External vacuuming equipment operates through first and second suction ports 425a, 426a, creating an adsorption force on the roller surface, selectively removing some of the adhesive from the dipped product. Compared to traditional direct pressure debinding methods, this solution uses adsorption force to achieve a contact-based, gentle debinding action, removing and collecting excess adhesive from the surface of the dipped product while effectively preventing material damage and ensuring uniform debinding and consistent quality.

[0186] The debonding roller rotary drive mechanism 43 is mounted on the debonding frame 41 and includes a rotary drive assembly and a rotary transmission assembly. The debonding roller rotary drive mechanism 43 operates in the same manner as the dipping roller rotary drive mechanism 34. The rotary transmission assembly connects the rotary drive assembly and the debonding roller assembly 42. The rotary transmission assembly is a belt drive or chain gear drive assembly, and is in driving connection with the sprocket end cap on one side of the lower debonding roller 422.

[0187] Furthermore, the debonding roller assembly 42 also includes expansion sleeves 429 disposed at both ends of the upper debonding roller shaft 425 and the lower debonding roller shaft 426. The expansion sleeves 429 are connected to the second slide 424 and can lock or unlock the upper debonding roller shaft 425 from the second slide 424. The expansion sleeves 429 are connected to the third and fourth side plates 423a, 423b and can lock or unlock the lower debonding roller shaft 426 from the third and fourth side plates 423a, 423b.

[0188] The structure of the second lifting drive assembly 428 is consistent with that of the first lifting drive assembly 338 described above, and will not be repeated here.

[0189] In the production line of the present invention, the dipping unit 3 and the debinding unit 4 are each equipped with an independent rotary drive device and transmission assembly. This design allows the rotational speed / linear speed of the dipping roller and the rotational speed / linear speed of the debinding roller to be independently adjusted and controlled, achieving optimal process conditions for each of the dipping and debinding processes.

[0190] In the production line of the present invention, a feeding device, a glue dipping device, a glue removal device, a drying device, a whole-sheet veneer equipment, a slice cutting device and a forming device are arranged in a front-and-rear manner. Through the synergistic effect of roller-pressing glue dipping, dynamic glue removal and drying and hot pressing, a continuous and automated production process is formed. This integrated design ensures the quality stability of the reconstituted board, improves production efficiency, and reduces manual intervention and waiting time between processes.

[0191] The production line of the embodiment of the present invention is suitable for low-quality raw materials such as fast-growing forest wood, bamboo and shrubs. It forms homogeneous high-strength reconstituted boards through directional assembly and hot pressing, broadening the industrial application scenarios of biomass resources.

[0192] An embodiment of the present invention further provides a method for producing a reconstituted plate, the method applying the aforementioned production line, the method comprising the following steps:

[0193] S1. Preparation of veneer: veneer includes bamboo strips and wood strips;

[0194] The preparation process of bamboo strips is as follows:

[0195] The bamboo tube is split by a bamboo splitting machine to obtain bamboo strips; the bamboo strips are graded according to their location and wall thickness; the same bamboo strip is divided into three sections along its length: upper section, middle section, and lower section; the sections are secondary graded according to their wall thickness; the graded bamboo strips are stacked, ensuring that the green side and yellow side of all bamboo strips face the same direction, and the larger and smaller diameter ends of the bamboo strips face the same direction; in subsequent processes, the bamboo strips or bamboo strip sections of the same grade are continuously processed;

[0196] The preparation process of the wood strips is as follows:

[0197] The logs are cut into segments according to the length required for production; after the segments are rounded, they are peeled into veneers of a certain thickness using a peeling machine;

[0198] S2, placing the stacked veneers on the feeding device 1; the veneers output by the feeding device 1 are sent to the decomposition device 2 for processing into fiberized veneers;

[0199] S3. The fiberized veneer is conveyed via conveyor 9 to the dipping unit 3, where glue is applied to the fiberized veneer to produce a dipping product. The fiberized veneer passes sequentially through the roller gap formed by the upper dipping roller 331 and the lower dipping roller 332 in the dipping unit 3. A phenolic resin glue can be used as the glue, with a solids content of 25%. During the roller dipping process in the dipping unit 3, the compression ratio of the veneer is controlled at 50% to fully open the fiber channels and facilitate glue penetration. The roller speed is controlled at 40 m / min.

[0200] S4. The excess glue liquid of the impregnated product is discharged in the discharge device 4 to obtain a discharged product; the amount of glue applied to the discharged product is controlled at 15% to 16%.

[0201] S5, the debinding product is dried in the drying device 5 via the conveying device 9 to obtain a dried product. The debinding product is placed in the drying equipment and dried to a moisture content of 10% to 12% to meet the process requirements of hot pressing molding.

[0202] S6. The dried product is woven into a continuous curtain by the veneer unit 6. The continuous curtain is then cut into sheets by the sheeting unit 7. The dried product is delivered by the drying conveyor 52 and overlapped on the intermediate conveyor 61. The overlap distance between the dried products is 2-5 mm.

[0203] S7. The curtain sheets are stacked and laid on the lower pressing plate 83 to form slabs, and then transferred to the bottom of the upper pressing plate 86 through the transfer mechanism 82. The upper pressing plate 86 and the lower pressing plate 83 press the slabs into reconstituted plates.

[0204] The lower platen 83 receives curtain slats from the discharge end of the rear conveyor 72 and stacks the assembled sheets on it. When the stacked curtain slats reach the required number, the transfer mechanism 82 operates, driving the lower platen 83 horizontally toward the upper platen 86. When the second position sensor 88 detects that the lower platen 83 is in place, the transfer mechanism 82 stops, and the upper platen lift drive 85 lowers the upper platen 86. The upper and lower plates 86 and 83 heat and pressurize the stacked curtain slats. After the heating and pressurization period has expired, the upper platen lift drive 85 raises the upper platen 86, and the transfer mechanism 82 continues to move the lower platen 83 forward. When the third position sensor 89 detects that the lower platen 83 is in place, the transfer mechanism 82 stops, and an operator removes the formed reassembled sheet from the lower platen 83, completing the reassembled sheet preparation process. The transfer mechanism 82 returns the lower platen 83 to one end of the transfer mechanism located below the rear conveyor 72 for the next material receiving process.

[0205] The hot pressing conditions are: a temperature of 130-150°C, a pressure of 2.0-8.0 MPa, and a time of 1.0-2.0 min / mm of sheet thickness. The density of the reconstituted sheet after pressing is 0.70-1.30 g / cm³.

[0206] Furthermore, during the dipping and degumming process, a 50% veneer compression ratio, combined with a 40 m / min roller speed and degumming roller rotation speed, can achieve a gluing rate of 800-1000 kg / hour for the fiberized veneer. The degummed product can then be directly fed into the dryer for drying. In contrast, during the traditional cage-type dipping process, a cage holds approximately 300-450 kg of fiberized veneer, with dipping and draining times of approximately 30-40 minutes, followed by a 4-hour equilibration period. This technology significantly increases gluing speed.

[0207] The reconstituted board production method of this invention improves product performance and production efficiency by optimizing moisture content control, roller-pressing impregnation, dynamic debinding, and the synergistic effects of drying and hot pressing. The resulting reconstituted board exhibits enhanced dimensional stability, with a water absorption thickness expansion of 4.40% after a 28-hour cycle test (4 hours of boiling in water, 20 hours of drying at 63°C, and 4 hours of boiling). This represents a reduction of over 50% compared to reconstituted board produced using the cage-type impregnation method.
