Description

Technical Field

[0001] This invention relates to the field of reconstituted board manufacturing, and in particular to a continuous production line and method for reconstituted board. Background Technology

[0002] Reconstituted boards (such as reconstituted bamboo and reconstituted wood) are high-performance, high-value-added, green, low-carbon, and environmentally friendly composite materials made by combining bamboo or wood with adhesives through directional recombination technology. Due to their excellent physical and mechanical properties and environmental characteristics, they are widely used in construction, furniture, landscaping, transportation, and other fields.

[0003] Current reconstituted plywood production processes include delamination, glue impregnation, drying, piling and assembly, and pressing. Equipment is scattered, and manual handling is sometimes necessary. Companies primarily use an intermittent cage-type glue application process, where veneers are placed in a specially designed cage, left in a glue tank for a period, then lifted out to drain excess glue. After equilibration for 4 hours to 7 days, they are dried again, resulting in a long production cycle.

[0004] Furthermore, poor coordination between processes can lead to adhesive dripping and environmental contamination during the transfer of the impregnated product, or changes in the adhesive layer's condition (such as partial pre-curing of the adhesive), affecting process stability and product quality stability. These issues hinder further improvements in the quality of reconstituted board products and the reduction of production costs.

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

[0072] In a second aspect, the present invention provides a method for producing reconstituted plywood, the method utilizing the continuous production line for reconstituted plywood of the first aspect of the present invention, the method comprising the following steps:

[0073] S1. Veneer preparation: Veneers consist of bamboo strips and wood strips;

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

[0075] Bamboo tubes are split into bamboo strips using a bamboo splitting machine. The bamboo strips are graded according to their location and wall thickness. Each bamboo strip is divided into three sections along its length: upper, middle, and lower. Sub-grading is performed based on the wall thickness of each section. The graded bamboo strips are then stacked, ensuring that the green and yellow sides of all strips face the same direction, and that the larger and smaller diameter ends of the strips face the same direction. In subsequent processes, bamboo strips or strip sections of the same grade are processed continuously.

[0076] The preparation process of the wooden strips is as follows:

[0077] The logs are cut into segments according to the required length for production; after the segments are rounded, they are veneered into a certain thickness using a rotary cutter.

[0078] S2. Place the stacked veneers on the feeding device 1; the veneers output from the feeding device 1 are sent to the delamination device 2 to be processed into fiberized veneers.

[0079] S3. The fiber veneer is conveyed to the impregnation device 3 via the conveying device 9, and the impregnation product is obtained by applying glue to the fiber veneer.

[0080] S4. The excess adhesive is discharged from the adhesive discharge device 4 to obtain the discharged product.

[0081] S5. The degummed product is dried in the drying device 5 via the conveying device 9 to obtain the dried product.

[0082] S6. The dried product is woven into a continuous curtain in the sheet-forming equipment 6; the continuous curtain is then cut into sheets by the sheet-cutting device 7 to form curtain slats.

[0083] S7. After the slats are stacked and laid on the lower pressure plate 83 to form a slab, they are conveyed to the area below the upper pressure plate 86 by the transfer mechanism 82. The upper pressure plate 86 and the lower pressure plate 83 press the slab into a reconstituted board.

[0084] The continuous production line and method for reconstituted boards provided by this invention have at least the following advantages compared with the prior art:

[0085] (1) In the continuous production line of the reconstituted board of the present invention, the feeding device, the glue dipping device, the glue discharging device, the drying device, the whole sheet veneer equipment, the cutting and sheeting device and the forming device are arranged in front and behind, forming a continuous and automated production process. 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 problem of speed matching between the continuity of the sewing / weaving process and the downstream cutting sheet device or subsequent hot pressing forming process, so that the downstream equipment can operate more smoothly and reduce downtime caused by fluctuations in upstream material supply speed or downstream processing speed limitations, thereby improving the efficiency and continuity of the entire production line.

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

[0128] To make the technical problem to be solved, the technical solution and advantages of the present invention clearer, the following description will be provided in conjunction with the accompanying drawings. Figures 1 to 31The technical solution of the present invention will be clearly and completely described in conjunction with specific embodiments.

[0129] This application provides a continuous production line for reconstituted board (hereinafter referred to as the "production line"), such as Figure 1 As shown, 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 separating device 2; arranged sequentially along the horizontal direction of the feeding device 1 are a separating device 2 for separating the veneers, a resin impregnation device 3 for impregnating the fiberized veneers with resin, and a resin discharge device 4 for discharging excess resin from the impregnated product. Figure 2 As shown; along the vertical direction of the conveying device 9, a drying device 5, a sheet-forming device 6, a sheet-cutting device 7, and a forming device 8 are arranged sequentially, as follows: Figure 3 As shown. The dispersing device 2 and the impregnation device 3, and the glue discharge device 4 and the drying device 5 are connected by a conveying device 9.

[0130] Specifically, such as Figure 6 and Figure 7 As shown, the feeding device 1 includes a feeding frame 11, on which a main feeding belt conveyor 12 is mounted. The main feeding belt conveyor 12 includes a first conveyor support 121 fixed to the feeding frame 11, rotating rollers disposed at both ends of the first conveyor support 121, and a first conveyor belt 122 sleeved on the rotating rollers. The rotating rollers are driven to rotate by a motor, thereby driving the first conveyor belt to rotate. The operator places the veneer on the first conveyor belt 122 of the main feeding belt conveyor 12, and the first conveyor belt 122 carries the veneer to the unloading device 2. Further, the feeding device 1 also includes side feeding belt conveyors 13 disposed on the feeding frame 11 and located on both sides of the main feeding belt conveyor 12. The side feeding belt conveyor 13 includes a second conveyor support 131 fixed to the feeding frame 11, rotating rollers disposed at both ends of the second conveyor support 131, and a second conveyor belt 132 sleeved on the rotating rollers. The discharge end of the side feed belt conveyor 13 faces the main feed belt conveyor 12. By controlling the feeding sequence and the rotation speed of the second conveyor belt 132, the two side feed belt conveyors 13 alternately feed material to the main feed belt conveyor 12.

[0131] Furthermore, the first conveyor support 121 includes a vertical support portion 121a and an inclined support portion 121b. The bottom end of the vertical support portion 121a is fixedly connected to the feeder frame 11, the fixed end of the inclined support portion 121b is located at the top end of the vertical support portion 121a, and the free end of the inclined support portion 121b faces the second conveyor belt 132. A guide groove is formed between the two first conveyor supports 121 on both sides to ensure that the veneer is conveyed on the feeding device 1 without deviation, providing quality assurance for subsequent stripping, impregnation, and glue discharge.

[0132] Furthermore, the feeding device 1 also includes a storage frame 14 disposed above the side feeding belt conveyor 13, in which veneers are stacked. Support plates 15 are fixedly mounted on the second conveyor supports 131 on both sides of the side feeding belt conveyor 13. The support plates 15 extend upwards perpendicular to the horizontal plane of the second conveyor belt 132 and support the storage frame 14. The distance between the bottom end of the storage frame 14 and the second conveyor belt 132 is greater than the thickness of one veneer but less than the thickness of two veneers. When the side feeding belt conveyor 13 is running, it pulls the bottom veneer of the storage frame 14 onto the first conveyor belt 122 via the second conveyor belt 132. A pusher plate can be disposed on the second conveyor belt 132 along the conveying direction to push the veneer out.

[0133] Considering that the diameter of bamboo varies along its growth direction when the reconstituted board is made of reconstituted bamboo material, the prepared bamboo strips have a large width edge and a small width edge. When stacking the materials, it is ensured that the large width edge and the small width edge face the same direction. 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 material to the main feeding belt conveyor 12. Through the above-mentioned alternating feeding method, the dried product entering the whole sheet veneer equipment 6 is arranged in a complementary manner in the width direction, thereby ensuring that the overall width of the continuous curtain formed by weaving is uniform.

[0134] In practical applications, in conjunction with the above embodiments, the unwinding device 2, the glue-impregnating device 3, and the glue-discharging device 4 all adopt a roller structure.

[0135] The debonding device 2 comprises parallel debonding roller groups, each group including an upper debonding roller and a lower debonding roller, both with toothed surfaces. The debonding device 2 also includes a drive mechanism for rotating the upper and lower debonding rollers. During operation, the upper and lower debonding rollers cooperate, applying a rolling and kneading effect to the board to promote fiber separation and extension, thereby causing the board to expand uniformly in the transverse direction. The debonding device 2 is a conventional setup in the prior art and is not within the scope of this invention; therefore, it will not be described further in the embodiments of this invention.

[0136] The drying device 5 includes a drying chamber 51 and a drying conveying mechanism 52. The drying chamber 51 has a drying inlet and a drying outlet at opposite ends. The drying conveying mechanism 52 extends from its inlet end to its outlet end. The outlet end of the conveying device 9 between the glue discharge device 4 and the drying device 5 is laterally connected to the inlet end of the drying conveying mechanism 52. The veneer self-feeding device 1 conveys the veneer along its length to the conveying device 9 and along its width on the drying conveying mechanism 52. A hot air mechanism is installed inside the drying chamber 51 to dry the glue-discharged product with hot air. Specifically, the hot air mechanism includes a heater and multiple fans arranged along the conveying direction. The drying conveying mechanism 52 has the same conveying structure as the conveying device 9, consisting of a motor-driven rotating roller that drives a belt. To ensure that the glue-removed product from the conveyor 9 moves along the width of the sheet in the drying conveyor 52, the belt of the drying conveyor 52 is provided with grooves or protrusions, the edges of which correspond to the shape of the sheet. Additionally, ventilation holes are provided on the belt within the grooves or protrusions to ensure uniform drying of the glue-removed product.

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

[0138] The workflow and alternation mechanism of the single-sheet veneer equipment 6: The sewing mechanism 62 continuously sews single sheets of veneer into a continuous curtain. The continuous curtain is conveyed to the winding mechanism 63. The two take-up trays 631 operate alternately: one take-up tray 631 is in the winding state, continuously winding up the continuous curtain woven by the sewing mechanism 62; the other take-up tray 631 is in the supply state, releasing the wound continuous curtain in the reverse direction to supply the downstream cutting and sizing device 7. When the take-up tray 631 that is winding up (i.e., the one closer to the sewing mechanism 62) reaches a full state, a switching process is triggered. The first cutting mechanism 64 actuates, cutting the continuous curtain woven by the sewing mechanism 62. The winding action switches from the full take-up tray 631 to another prepared (usually empty or not full) take-up tray 631, which enters the winding state. At the same time, the previously full take-up tray 631 switches to the supply state and begins to supply material to the downstream cutting and sizing device 7.

[0139] The alternating buffer mechanism of the sheet-forming equipment 6 effectively solves the speed matching problem between the continuous (relatively fast) sewing / weaving process and the downstream sheet-cutting device 7 or subsequent hot-pressing process (relatively slow or requiring intermittent operation). It provides buffer time for downstream processes (especially hot-pressing), enabling downstream equipment to operate more smoothly and reducing downtime caused by fluctuations in upstream material supply speed or limitations in downstream processing speed, thereby significantly improving the efficiency and continuity of the entire production line.

[0140] The transition conveyor 61 is configured to have a lower speed than the drying conveyor 52. The vertical height difference and speed difference between the transition conveyor 61 and the drying conveyor 52 are suitable for causing the dried product to overlap on the transition conveyor 61. Figure 4 As shown. The overlap distance between dried products is 2~5mm (the overlap distance is consistent for reconstituted boards in the same batch).

[0141] like Figure 3 As shown, the slitting device 7 includes a front conveying mechanism 71 and a rear conveying mechanism 72 arranged sequentially in the continuous curtain conveying direction. 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 slitting pieces.

[0142] The structure of the sheet-forming equipment 6 and the sheet-cutting device 7 is existing technology and will not be described in detail in this embodiment. For reference, please refer to the relevant technology disclosed in Chinese Patent No. CN 120206594 A.

[0143] The forming device 8 includes a forming frame 81, on which a transfer mechanism 82 is mounted. One end of the transfer mechanism 82 is located below the rear conveyor mechanism 72. A lower pressure plate 83 is slidably mounted on the transfer mechanism 82. The lower pressure plate 83 receives the curtain sheets transferred from the discharge end of the rear conveyor mechanism 72. Due to the height difference between the transfer mechanism 82 and the rear conveyor mechanism 72, multiple curtain sheets are stacked on the lower pressure plate 83 to form blanks. A hot press support 84 is fixedly mounted in the middle of the forming frame 81. The hot press support 84 is equipped with an upper pressure plate lifting drive mechanism 85. An upper pressure plate 86 is mounted at the output end of the upper pressure plate lifting drive mechanism 85. Both the lower pressure plate 83 and the upper pressure plate 86 have built-in heaters, which are metal resistance wires.

[0144] A first position sensor 87 is installed at one end of the forming frame 81 below the rear conveyor mechanism 72, a second position sensor 88 is installed at the position of the forming frame 81 corresponding to the hot press bracket 84, and a third position sensor 89 is installed at the end of the forming frame 81 away from the rear conveyor mechanism 72. The position sensors detect the position of the lower pressure plate 83 and transmit the signal to the control system, thereby controlling the transfer mechanism 82 to operate or stop. The position sensors are preferably photoelectric switches, which can detect the arrival and departure of the lower pressure plate.

[0145] In its initial state, the lower pressure plate 83 is located at one end of the transfer mechanism below the rear conveyor mechanism 72, as shown below. Figure 8 As shown, the first position sensor 87 detects that the lower pressure plate 83 is in position. The lower pressure plate 83 receives the slats conveyed from the discharge end of the rear conveying mechanism 72 and stacks the blanks on the lower pressure plate 83, as shown. Figure 5 As shown. When the stacked curtain slats reach the designed number of slats, the transfer mechanism 82 drives the lower pressure plate 83 to move horizontally towards the upper pressure plate 86. When the second position sensor 88 detects that the lower pressure plate 83 has reached its position, the transfer mechanism 82 stops operating, and the upper pressure plate lifting drive mechanism 85 drives the upper pressure plate 86 to descend. The upper pressure plate 86 and the lower pressure plate 83 heat and press the stacked curtain slats to form them, as shown. Figure 9 As shown. After heating and pressurizing to a preset time, the upper pressure plate lifting drive mechanism 85 drives the upper pressure plate 86 to rise. The transfer mechanism 82 operates, driving the lower pressure plate 83 to continue moving forward. When the third position sensor 89 detects that the lower pressure plate 83 has reached its position, the transfer mechanism 82 stops operating. The operator removes the formed reconstituted sheet from the lower pressure plate 83, completing the reconstituted sheet preparation process. The transfer mechanism 82 drives the lower pressure plate 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 components such as cylinders, oil cylinders, and electric push rods, and the transfer mechanism 82 includes, but is not limited to, linear drive components such as screw slide structure, gear and rack transmission structure, and synchronous belt structure, as long as they can provide linear driving force.

[0147] The conveying device 9 can employ a multi-set conveyor roller structure, driven by a conveyor frame motor and synchronized via a chain drive system to ensure smooth board transport. Alternatively, the conveying device 9 can be a belt conveyor. The upper surface of the conveying plane of the conveying device 9 is strictly aligned with the outlet of the sizing device 2 and the inlet of the glue-dip device 3, and also strictly aligned with the outlet of the glue-discharging device 4 and the inlet of the drying device 5. As a key transmission unit connecting the sizing device 2 and the glue-dip device 3, and the glue-discharging device 4 and the drying device 5, the conveying device 9 achieves continuous board transport, buffer adjustment, and speed matching. By dynamically adjusting the transmission rate, the conveying device 9 effectively coordinates the production rhythm differences between the upstream sizing device 2 and the downstream glue-dip device 3, and between the glue-discharging device 4 and the drying device 5. Furthermore, the conveying device 9 can provide short intervals during transport, facilitating online quality inspection of the fiberized veneer and glue-discharging products and timely removal of defective products.

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

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

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

[0151] A glue tank 32 is mounted on the glue dipping frame 31, and the glue solution for dipping is contained within the glue tank 32. Specifically, the glue tank 32 includes a box structure formed by side panels 321 and a bottom panel 322, with an opening at the top and closed on all sides and bottom. 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 the opposite sides of the side panels 321 along the board conveying direction. The roller sealing plates 325 have through holes 325a, which provide a channel 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 provided inside the ring 325b. The ring 325b provides a chamber for accommodating and fixing the sealing ring, and the sealing ring prevents glue leakage at the connection point. The lower dip roller shaft 336 passes through the through hole 325a of the roller sealing plate 325 and is sealed and connected to the sealing ring inside the ring sleeve 325b.

[0152] The sealing ring tightly wraps around the rotating lower dip 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 the uniformity of the dip depth.

[0153] The glue supply mechanism 37 includes a glue tank 371 connected by a pipeline and a power pump 372. 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 includes a slag receiving hopper 381 and a slag discharge guide cylinder 382 disposed below the slag discharge outlet pipe 324. One end of the slag discharge guide cylinder 382 is located inside the slag receiving hopper 381 and has filter holes. A propeller 383 is disposed inside the slag discharge guide cylinder 382, ​​and a rotary drive motor is disposed at the end of the propeller 383. A downward-facing slag outlet 384 is opened in the middle of the slag discharge guide cylinder 382. The slag receiving hopper 381 receives the residue and waste glue discharged from the slag discharge outlet pipe 324. The waste glue is discharged from the filter holes, and the residue is discharged from the slag outlet 384 by the propeller 383.

[0155] There are at least three dip roller assemblies 33, all of which are sequentially arranged on the dip roller frame 31 along the conveying direction of the fiberized veneer. The dip roller assemblies 33 are located in the glue tank 32 and are used for extruding and impregnating the fiberized veneer with glue. The dip roller assembly 33 includes an upper dip roller 331 and a lower dip roller 332 arranged vertically, and the fiberized veneer is extruded and impregnated with glue between the upper dip roller 331 and the lower dip roller 332.

[0156] The dip roller assembly 33 further includes: a first frame 333, including a first side plate 333a and a second side plate 333b fixedly mounted on the dip frame 31; two first sliding plates 334, which are slidably connected to the first side plate 333a and the second side plate 333b respectively; an upper dip roller shaft 335, whose two ends are respectively connected to the first sliding plates 334 on the left and right sides via bearings; an upper dip roller 331 coaxially fixedly mounted on the upper dip roller shaft 335; a lower dip roller shaft 336, whose two ends are respectively connected to the first side plate 333a and the second side plate 333b via bearings; a lower dip roller 332 coaxially fixedly mounted on the lower dip roller shaft 336; and a first gear disc assembly 337, including a coaxially fixed... A first upper gear disk 337a is mounted on the upper impregnation roller shaft 335 and located outside the first slide plate 334, and a first lower gear disk 337b is coaxially fixed on the lower impregnation roller shaft 336 and meshes with the first upper gear disk 337a; a first lifting drive assembly 338 is mounted on the first frame 333 and connected to the first slide plate 334; the first lifting drive assembly 338 drives the first slide plate 334 to move up and down, thereby causing the upper impregnation roller 331 to move toward or away from the lower impregnation roller 332. The extrusion gap formed by the upper and lower impregnation rollers, which are arranged vertically and vertically, applies controllable pressure to the fiber veneer, which not only promotes the penetration of the glue, but also squeezes out the air inside the fiber veneer, avoiding the residual air bubbles that cause uneven impregnation.

[0157] The first upper gear disk 337a is fixed on the upper impregnation roller shaft 335, and the first lower gear disk 337b is fixed on the lower impregnation roller shaft 336, and the two are always in a meshed state. Regardless of the height of the upper impregnation roller 331 (i.e., regardless of the change in the roller gap), this pair of meshing gear disks forcibly ensures that the upper impregnation roller 331 and the lower impregnation roller 332 rotate in opposite directions at exactly the same linear speed (rotational speed). When the fiber veneer is held between the upper and lower rollers for conveying, if the speeds of the two rollers are inconsistent, it can cause the material to be stretched, wrinkled, or even torn. Forced synchronization completely eliminates this risk. Speed ​​synchronization ensures that the traction force and impregnation effect on the material in the roller gap are consistent, thereby obtaining uniform glue impregnation. Only one dip roller shaft (lower dip roller shaft 336) needs to be driven to drive the other dip roller shaft (upper dip roller shaft 335) to rotate synchronously through gear meshing. There is no need to configure a complex floating drive mechanism (such as universal coupling, transmission belt tension adjustment mechanism, etc.) separately for the upper roller, which simplifies the design and cost of the drive system.

[0158] The linear drive sources of the first lifting drive assembly 338 and the second lifting drive assembly 428 include, but are not limited to, linear drive components such as cylinders, hydraulic cylinders, and electric actuators, as long as they can provide linear driving force. The output end of the linear drive source is connected to the slide plate to transmit the force. In some specific embodiments, the first frame 333 also includes an upper horizontal plate 333c, the two ends of which are fixed to the top ends of the first side plate 333a and the second side plate 333b, respectively. The specific composition and structure of the first lifting drive assembly 338 will be described in detail below.

[0159] The first lifting drive assembly 338 is a linked worm gear jack, and the output end of the worm gear jack is fixedly connected to the first slide plate 334. The worm gear jack also has a position self-locking device to ensure that the height of the pressure roller does not change due to the force on the pressure roller during operation, thus affecting the pressure change. Limit switches are installed at both the upper and lower positions of the first slide plate 334 to prevent the pressure roller from exceeding its working stroke and damaging the equipment. Worm gear jacks are existing technology, and will not be described further in this embodiment.

[0160] The robust frame, sliding plate guides, and bearing supports provide the necessary rigidity, stability, and reliability for the entire assembly's operation (especially lifting and rotation). The bearings ensure smooth, low-friction rotation of both upper and lower roller shafts, allowing for radial loads (primarily material pressure and gear meshing forces) while permitting a degree of axial float or positioning. This is fundamental to ensuring the long-term stable operation of the equipment.

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

[0162] In this embodiment of the invention, the rotary drive assembly consists of a servo motor 341 and a reducer 342 connected to the servo motor 341 via a belt. A rotary transmission assembly connects the rotary drive assembly and the dip roller assembly 33. This rotary transmission assembly is either a belt drive or a chain and gear drive assembly, connected to the reducer 342 and driven by the lower dip roller shaft 336.

[0163] The rotary transmission assembly of this invention includes: a drive gear 343 disposed at the output end of a reducer 342; the drive gear 343 directly meshes with a first lower gear disc 337b of two adjacent dipped roller assemblies 33; a first driven wheel 344 and a second driven wheel 345 are disposed at the end of the lower dipped roller shaft 336 and located outside the first lower gear disc 337b. The dipped roller assemblies 33 not directly meshed with the drive gear 343 achieve linkage transmission through the first driven wheel 344, the second driven wheel 345 at the end of the lower dipped roller shaft 336 of adjacent assemblies, and a transmission belt 346 surrounding them.

[0164] In embodiments of the present invention, such as 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 driven wheel 344 and the second driven wheel 345. It is suitable for high torque scenarios and matches the sprockets. The dip roller assembly 33 is arranged in five groups from front to back. The driving gear 343 directly meshes with the first lower gear disk 337b of the third and fourth dip roller assemblies 33, respectively. The dip roller assemblies 33 that are not directly meshed by the driving gear 343 (between the first and second dip roller assemblies 33, between the second and third dip roller assemblies 33, and between the fourth and fifth dip roller assemblies 33) achieve linkage transmission through the first driven wheel 344, the second driven wheel 345, and the transmission belt 346.

[0165] The first driven pulley 344 and the second driven pulley 345 can be synchronous pulleys, and the transmission belt 346 is a synchronous belt that matches the first driven pulley 344 and the second driven pulley 345. It is suitable for scenarios that require noise reduction and anti-slip, and is matched with the synchronous pulley.

[0166] The drive gear 343 directly drives two adjacent sets of dipped roller assemblies 33 to form the main transmission core, ensuring high torque output and avoiding single-point drive overload; the drive gear 343 directly meshes with the first lower gear disk 337b to provide a reference speed, and the transmission belt linkage group follows synchronously, avoiding speed deviation caused by excessively long transmission chains in multi-roller groups.

[0167] The drive gear 343 drives the two sets of pressure rollers in the middle position, placing the power input in the middle of the system, reducing the difference in transmission chain length on both sides, and reducing vibration caused by uneven torque transmission. The middle drive mode distributes the load on the transmission belt, avoiding transmission belt wear problems caused by excessively long transmission paths at the end pressure rollers. In addition, the first lower gear disc 337b, the first driven pulley 344, and the second driven pulley 345 are coaxially fixed to the end of the lower dip roller shaft 336, eliminating the need for an additional transmission shaft, reducing lateral installation space, and making it suitable for compact equipment. The rotary transmission assembly adopts a hybrid drive mode of "direct meshing-stage transmission belt drive", which simplifies the structure while achieving efficient power distribution.

[0168] The fiber veneer is subjected to multiple continuous pressure impregnations using at least three impregnation roller assemblies 33 arranged sequentially along the conveying direction, ensuring that the adhesive fully and evenly penetrates the internal structure of the fiber veneer. A portion of the upper impregnation roller 331 and the entire lower impregnation roller 332 are immersed in the adhesive in the adhesive pool 32. The fiber veneer is impregnated by pressure between the upper and lower impregnation rollers 331 and 332, ensuring that the fiber veneer remains in contact with the adhesive throughout the entire impregnation process.

[0169] The impregnation device 3 also includes a feed bracket 35 and a discharge bracket 36 for supporting the veneer. The feed bracket 35 and discharge bracket 36 are respectively located at opposite ends of the impregnation frame 31, and are flush with the upper impregnation roller 331 and the lower impregnation roller 332. The free end of the feed bracket 35 connects to the discharge end of the conveying device 9, guiding the veneer precisely into the roller gap. Its bearing surface forms a smooth transition with the roller gap, preventing the veneer from getting stuck. The free end of the discharge bracket 36 connects to the feed inlet of the glue discharge device 4, facing between the upper glue discharge roller 421 and the lower glue discharge roller 422, receiving the impregnated veneer. Its horizontal extension length needs to take into account the material's sag characteristics. The feed bracket 35 and discharge bracket 36 together form a continuous support surface, preventing warping and deformation of the veneer and maintaining its flatness during the impregnation process. The height of the fixed end of the discharge bracket 36 is lower than the height of its free end. During the process of conveying the dipped product to the glue discharge device 4, some of the glue liquid can flow back to the glue tank 32 along the discharge bracket 36, avoiding excess glue liquid from being carried into the glue discharge device 4 and causing glue liquid waste.

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

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

[0172] There are at least two glue discharge roller assemblies 42, and all glue discharge roller assemblies 42 are sequentially arranged on the glue discharge frame 41 along the conveying direction of the glue-impregnated product, for discharging excess glue from the glue-impregnated product. The glue discharge roller assembly 42 includes an upper glue discharge roller 421 and a lower glue discharge roller 422 arranged vertically, and the glue-impregnated product passes between the upper glue discharge roller 421 and the lower glue discharge roller 422.

[0173] The upper and lower glue-discharging rollers 421 and 422 discharge the glue from the impregnated product by extrusion, and the extrusion-type glue discharge structure is consistent with the structure of the impregnating roller assembly 33. Alternatively, the upper and lower glue-discharging rollers 421 and 422 can also discharge the glue from the impregnated product using a negative pressure method. Specifically, the negative pressure glue discharge structure is as follows:

[0174] like Figures 27 to 31 As shown, the glue discharge roller assembly 42 also includes a second frame 423, a second slide plate 424, an upper glue discharge roller shaft 425, a lower glue discharge roller shaft 426, a second gear disk 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 fixedly mounted on the glue dispensing frame 41, which are opposite to each other and are used to support the second slide plate 424, the upper glue dispensing roller shaft 425 and the lower glue dispensing roller shaft 426. There are two second slide plates 424, which are slidably connected to the third side plate 423a and the fourth side plate 423b respectively.

[0176] The upper and lower rubber roller shafts 425 and 426 are hollow structures. The upper roller shaft 425 has a first air intake 425a at one or both ends, and the lower roller shaft 426 has a second air intake 426a at one or both ends. Both air intakes 425a and 426a are connected to an external air extraction device. The upper roller shaft 425 has a first groove 425b in its middle, communicating with the first air intake 425a. The lower roller shaft 426 has a second groove 426b in its middle, communicating with the second air intake 426a. The first and second grooves 425b are positioned opposite each other. Both ends of the upper roller shaft 425 are fixedly connected to the second sliding plate 424, and both ends of the lower roller shaft 426 are fixed to the third side plate 423a and the fourth side plate 423b, respectively. The second gear assembly 427 includes an upper gear end cap 427a fixedly disposed on one side of the upper rubber roller 421 and a lower gear end cap 427b fixedly disposed on one side of the lower rubber roller 422, with the upper gear end cap 427a and the lower gear end cap 427b meshing together. A second lifting drive assembly 428 is disposed on the second frame 423 and connected to the second slide plate 424; the second lifting drive assembly 428 drives the second slide plate 424 to move up and down, thereby causing the upper rubber roller 421 to move toward or away from the lower rubber roller 422. The upper and lower rubber rollers, arranged vertically and vertically, form a precise gap, which effectively removes excess adhesive and prevents excessive compression that could damage the structure of the impregnated product or cause excessive adhesive loss, thus affecting the bonding strength.

[0177] The upper rubber roller 421 is a solid cylinder, coaxially sleeved on the upper rubber roller shaft 425 and rotating relative to it; the side wall of the upper rubber roller 421 has a first through hole 421a arranged in a circumferential and axial array; when the upper rubber roller 421 rotates, the first groove 425b communicates with the corresponding first through hole 421a. The lower rubber roller 422 is a solid cylinder, coaxially sleeved on the lower rubber roller shaft 426 and rotating relative to it; the side wall of the lower rubber roller 422 has a second through hole 422a arranged in a circumferential and axial array; when the lower rubber roller 422 rotates, the second groove 426b communicates with the corresponding second through hole 422a.

[0178] The upper roller 421 has an axial through hole at its center, through which the upper roller shaft 425 passes, with its outer wall fitting against the inner wall of the upper roller 421. The lower roller 422 has an axial through hole at its center, through which the lower roller shaft 426 passes, with its outer wall fitting against the inner wall of the lower roller 422. Both the upper and lower roller shafts 425 and 426 are hollow, serving as channels for conveying adhesive and also as the rotational axes of the upper and lower rollers 421 and 422, respectively.

[0179] A roller end cap is fixedly connected to the other end face of the upper rubber roller 421 opposite to the upper gear end cap 427a. A sprocket end cap is fixedly connected to the other end face of the lower rubber roller 422 opposite to the lower gear end cap 427b. The sprocket end cap is used to connect to the external second rotary transmission assembly 240.

[0180] The upper gear end cover 427a and the roller end cover rotate relative to the upper row of rubber roller shafts 425, while the lower gear end cover 427b and the sprocket end cover rotate relative to the lower row of rubber roller shafts 426. Specifically, bearings are provided on the upper gear end cover 427a and the roller end cover, and the upper row of rubber roller shafts 425 passes through two bearings. Bearings are provided on the lower gear end cover 427b and the sprocket end cover, and the lower row of rubber roller shafts 426 passes through two bearings.

[0181] Roller seals are provided on the outer wall of the upper roller shaft 425 between the upper gear end cover 427a and the upper roller 421, and between the roller end cover and the upper roller 421. Roller seals are also provided on the outer wall of the lower roller shaft 426 between the lower gear end cover 427b and the lower roller 422, and between the sprocket end cover and the lower roller 422. The roller seals improve the sealing of the component connection and provide effective adsorption force for the upper roller 421 and the lower roller 422.

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

[0183] The upper roller 421 has a first through hole 421a arranged in a circumferential and axial array on its side wall, and the lower roller 422 has a plurality of second through holes 422a. The diameters of the first through holes 421a and the second through holes 422a can be designed according to the design requirements of the impregnated product. It can be understood that when the diameters of the first through holes 421a and the second through holes 422a are large, the adsorption force at the location of the first through holes 421a and the second through holes 422a is large; when the diameters of the first through holes 421a and the second through holes 422a are small, the adsorption force at the location of the first through holes 421a and the second through holes 422a is small.

[0184] The upper roller 421 has a set of first through holes 421a arranged axially in one row, and similarly, the lower roller 422 has a set of second through holes 422a arranged axially in one row. The distance between adjacent rows of first through holes 421a and / or second through holes 422a can be designed according to the design requirements of the dipped product. It can be understood that when the distance between adjacent rows of first through holes 421a and / or second through holes 422a is large, the adsorption force of the roller assembly is small; when the distance between adjacent rows of first through holes 421a and / or second through holes 422a is small, the adsorption force of the roller assembly is large.

[0185] The upper gear end cover 427a and the roller end cover rotate relative to the upper rubber discharge roller shaft 425, while the lower gear end cover 427b and the sprocket end cover rotate relative to the lower rubber discharge roller shaft 426. Specifically, bearings are provided on the upper gear end cover 427a and the roller end cover, and the upper rubber discharge roller shaft 425 passes through two bearings. Bearings are provided on the lower gear end cover 427b and the sprocket end cover, and the lower rubber discharge roller shaft 426 passes through two bearings. The first slot 425b of the upper rubber discharge roller shaft 425 opens downwards, and the second slot 426b of the lower rubber discharge roller shaft 426 opens upwards. During the rotation of the rollers, the two slots always remain in a relative state, both facing the glue-impregnated product. As the upper rubber discharge roller 421 and the lower rubber discharge roller 422 rotate, a portion of the first through hole 421a always corresponds to the first slot 425b, and the second through hole 422a always corresponds to the second slot 426b, thus achieving continuity in the glue discharge process. The external suction device operates through the first suction port 425a and the second suction port 426a, forming an adsorption force on the roller surface to selectively remove some of the adhesive liquid from the inside of the dipped product. Compared with the traditional direct pressure adhesive removal method, this solution achieves a contact-type and gentle adhesive removal effect through adsorption force, absorbing and collecting excess adhesive liquid from the surface of the dipped product, while effectively avoiding material damage and ensuring the uniformity of adhesive removal and the stability of the quality of the dipped product.

[0186] The glue-discharging roller rotation drive mechanism 43 is mounted on the glue-discharging frame 41. The glue-discharging roller rotation drive mechanism 43 includes a rotation drive assembly and a rotation transmission assembly. The driving method of the glue-discharging roller rotation drive mechanism 43 is the same as that of the glue-dipping roller rotation drive mechanism 34. The rotation transmission assembly connects the rotation drive assembly and the glue-discharging roller assembly 42. The rotation transmission assembly is a belt drive or chain gear drive assembly, and is connected to the sprocket end cap on one side of the lower glue-discharging roller 422.

[0187] Furthermore, the glue discharge roller assembly 42 also includes tension sleeves 429 respectively disposed at both ends of the upper glue discharge roller shaft 425 and the lower glue discharge roller shaft 426. The tension sleeves 429 are connected to the second slide plate 424, enabling the upper glue discharge roller shaft 425 to be locked or unlocked from the second slide plate 424. The tension sleeves 429 are connected to the third side plate 423a and the fourth side plate 423b, enabling the lower glue discharge roller shaft 426 to be locked or unlocked from the third side plate 423a and the fourth side plate 423b.

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

[0189] In the production line of this invention, the dipping device 3 and the discharging device 4 are each equipped with independent rotary drive devices and transmission components. This design allows for independent adjustment and control of the rotational speed / linear velocity of the dipping roller and the rotational speed / linear velocity of the discharging roller, enabling the dipping and discharging processes to achieve their respective optimal process conditions.

[0190] In the production line of this invention, the feeding device, impregnation device, glue discharge device, drying device, sheet-forming equipment, cutting and forming device are arranged in front and behind. Through the synergistic effect of roller impregnation, dynamic glue discharge and drying 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 this invention is suitable for low-quality raw materials such as fast-growing timber, bamboo and shrubs. It forms homogeneous, high-strength reconstituted boards through directional hot pressing, thus broadening the industrial application scenarios of biomass resources.

[0192] This invention also provides a method for producing reconstituted board, the method using the aforementioned production line, the method comprising the following steps:

[0193] S1. Veneer preparation: Veneers consist of bamboo strips and wood strips;

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

[0195] Bamboo tubes are split into bamboo strips using a bamboo splitting machine. The bamboo strips are graded according to their location and wall thickness. Each bamboo strip is divided into three sections along its length: upper, middle, and lower. Sub-grading is performed based on the wall thickness of each section. The graded bamboo strips are then stacked, ensuring that the green and yellow sides of all strips face the same direction, and that the larger and smaller diameter ends of the strips face the same direction. In subsequent processes, bamboo strips or strip sections of the same grade are processed continuously.

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

[0197] The logs are cut into segments according to the required length for production; after the segments are rounded, they are veneered into a certain thickness using a rotary cutter.

[0198] S2. Place the stacked veneers on the feeding device 1; the veneers output from the feeding device 1 are sent to the delamination device 2 to be processed into fiberized veneers.

[0199] S3. The fiber veneer is conveyed to the impregnation device 3 via the conveying device 9, where resin is applied to the fiber veneer to obtain the impregnated product. The fiber veneer passes sequentially through the roller gap formed by the upper impregnation roller 331 and the lower impregnation roller 332 in the impregnation device 3. Phenolic resin can be used as the resin, and the solid content in the resin is controlled at 25%. During the roller impregnation process in the impregnation device 3, the veneer compression rate is controlled at 50% to fully open the fiber channels and promote resin penetration. The roller speed is controlled at 40 m / min.

[0200] S4. The excess adhesive is discharged from the adhesive discharge device 4 to obtain the discharged adhesive product; the amount of adhesive applied to the discharged adhesive product is controlled at 15%~16%.

[0201] S5. The degummed product is conveyed by the conveying device 9 and dried in the drying device 5 to obtain a dried product. The degummed product is placed in the drying equipment and dried until the moisture content is 10%~12% to meet the process requirements of hot pressing.

[0202] S6. The dried product is woven into a continuous curtain in the sheet-forming equipment 6; the continuous curtain is then cut into sheets by the cutting device 7. After being output by the drying conveyor 52, the dried product overlaps on the transition conveyor 61, with an overlap distance of 2~5mm between the dried products.

[0203] S7. After the slats are stacked and laid on the lower pressure plate 83 to form a slab, they are conveyed to the area below the upper pressure plate 86 by the transfer mechanism 82. The upper pressure plate 86 and the lower pressure plate 83 press the slab into a reconstituted board.

[0204] The lower pressure plate 83 receives the slats conveyed from the discharge end of the rear conveyor mechanism 72 and stacks them on the lower pressure plate 83. When the stacked slats reach the designed number, the transfer mechanism 82 moves the lower pressure plate 83 horizontally toward the upper pressure plate 86. When the second position sensor 88 detects that the lower pressure plate 83 is in position, the transfer mechanism 82 stops, and the upper pressure plate lifting drive mechanism 85 drives the upper pressure plate 86 to descend. The upper pressure plate 86 and the lower pressure plate 83 heat and pressurize the stacked slats to form the slats. After heating and pressurizing for a preset time, the upper pressure plate lifting drive mechanism 85 drives the upper pressure plate 86 to rise, and the transfer mechanism 82 continues to move the lower pressure plate 83 forward. When the third position sensor 89 detects that the lower pressure plate 83 is in position, the transfer mechanism 82 stops, and the operator removes the formed reconstituted sheet from the lower pressure plate 83, completing the reconstituted sheet preparation process. The transfer mechanism 82 drives the lower pressure plate 83 back to one end of the transfer mechanism located below the rear conveyor mechanism 72 for the next receiving process.

[0205] The hot-pressing conditions are as follows: hot-pressing temperature: 130~150℃; hot-pressing pressure: 2.0~8.0 MPa; hot-pressing time: 1.0~2.0 min / mm thickness. The density of the pressed reconstituted board is 0.70~1.30 g / cm³.

[0206] Furthermore, during the impregnation and discharge processes, a 50% veneer compression rate combined with a roller speed of 40 m / min and a discharge roller speed allows for an application rate of 800-1000 kg / hour for the fiberized veneer. The discharged product can then be directly fed into a dryer for drying. In contrast, the traditional cage-type impregnation method involves approximately 300-450 kg of fiberized veneer per cage, with impregnation and discharge times of about 30-40 minutes, followed by a balancing period of over 4 hours. Therefore, this technology significantly increases the application speed.

[0207] The reconstituted board production method of this invention improves product performance and production efficiency through the synergistic effects of optimized moisture content control, roller impregnation, dynamic glue discharge, and drying hot pressing. The dimensional stability of the prepared reconstituted board is improved, and the water absorption thickness swelling rate after 28-hour cycle testing (4-hour boiling in water + 20-hour drying at 63℃ + 4-hour boiling in water) reaches 4.40%, which is more than 50% lower than the water absorption thickness swelling rate of reconstituted boards prepared by the cage impregnation method.
