Description

Technical Field

[0001] This invention relates to the field of bamboo processing, and in particular to an apparatus and method for preparing highly weather-resistant reconstituted bamboo. Background Technology

[0002] High-weather-resistant reconstituted bamboo is a type of artificial bamboo material with strong weather resistance and durability. Reconstituted bamboo is a new type of building material made from natural bamboo through special treatment and modification. Its manufacturing process typically involves treating the bamboo for rot, insects, and corrosion, and using high-temperature, high-pressure technology to recombine multiple bamboo stalks into a homogeneous structure.

[0003] The existing equipment typically involves first treating the bamboo with anti-corrosion and anti-mildew measures, then moving the treated bamboo to a glue-impregnation tank for glue impregnation, and finally moving it to a high-temperature pressing device for hot pressing. However, the existing equipment requires separate stations for glue impregnation and pressing, which results in repeated transportation of the bamboo. During the transportation process, the glue gradually solidifies, affecting the pressing operation during subsequent bonding work.

[0004] Therefore, a one-stop impregnation and hot-pressing structure has been developed to facilitate the preparation of highly weather-resistant reconstituted bamboo and avoid repeated handling of bamboo materials. Summary of the Invention

[0005] To overcome the shortcomings of existing devices that require separate stations for impregnation and pressing, resulting in repeated transportation of bamboo and the gradual solidification of glue during transportation affecting subsequent bonding pressing operations, this invention provides a one-stop impregnation and hot pressing structure, which facilitates the preparation of highly weather-resistant reconstituted bamboo and avoids the need for repeated handling of bamboo.

[0006] The technical solution is: a preparation device and method for highly weather-resistant reconstituted bamboo, including a base, a stationary frame, a drying balance processor, a feeding mechanism and a hot pressing mechanism. The stationary frame is connected to the upper left side of the base, the drying balance processor is connected to the upper right side of the base, the feeding mechanism for conveying bamboo raw materials is provided at the top of the base, and the hot pressing mechanism for hot pressing and shaping the bamboo is provided at the upper right side of the base.

[0007] Furthermore, the feeding mechanism includes a first sliding frame, a drive assembly, sliding blocks, and a placement frame. The first sliding frame is connected to the upper sides of both the front and rear of the base. The drive assembly is connected to the front first sliding frame. Sliding blocks are slidably connected to the right side of each first sliding frame. The drive assembly includes a motor and a lead screw. The motor is connected to the front first sliding frame, and the lead screw is connected to the motor output shaft. The lead screw is rotatably connected to the first sliding frame and threadedly connected to the adjacent sliding blocks. Placement frames are slidably connected to the upper parts of each sliding block. The placement frames are slidably connected to the first sliding frame. The left side of the first sliding frame, near the stationary frame, has a recessed structure, so that when the placement frame moves above the stationary frame, it slides downwards on the sliding blocks, carrying the bamboo material into the stationary frame for resin impregnation. The drive assembly controls the sliding blocks to move the placement frames, causing the placement frames to move on the first sliding frame to transport the bamboo material.

[0008] Furthermore, the hot pressing mechanism includes a multi-stage hydraulic cylinder, a hot pressing plate, guide rods, a rotating disk, a connecting plate, a docking plate, a rotating column, a sliding plate, a moving plate, a second sliding frame, a pressing plate, a first spring, a pushing plate, an extrusion component, a pull rod, a second spring, and a third spring. The multi-stage hydraulic cylinder is connected to the upper right side of the base. The front and rear ends of the multi-stage hydraulic cylinder are slidably connected to the hot pressing plate. Multiple guide rods are connected to the upper right side of the base, each guide rod having a threaded groove. Connecting plates are rotatably connected to the lower left and right sides of the hot pressing plate. A rotating disk is connected between the bottoms of adjacent connecting plates, and each rotating disk is slidably connected to an adjacent guide rod. The rotating disk moves upwards along the guide rod. Guided by the threaded grooves on the rod, rotation occurs, pulling the hot-pressing plates together via the connecting plate. This causes the hot-pressing plates to come closer together, clamping the bamboo material. Both sides of the hot-pressing plates are slidably connected to butt plates. When the hot-pressing plates move upwards or come closer together, they move the butt plates along with them. Multiple rotating columns are rotatably connected to the right side of the base. Each rotating column also has threaded grooves on its upper and lower parts. A sliding plate is slidably connected to the lower part of each rotating column, and a moving plate is slidably connected to the upper part of each sliding plate. The top of each moving plate is slidably connected to the adjacent butt plate. A second sliding frame is slidably connected between the upper parts of the rotating columns, and a pressure plate is slidably connected to the second sliding frame. The pressure plate is slidably connected to the left and right sides of the second sliding frame. Both upper sides are connected to the second sliding frame by a first spring. Multiple push plates are connected to the upper part of the base. Extrusion components are connected to the lower sides of both the front and rear sides of the mating plate. Each extrusion component is in pressure engagement with an adjacent push plate. A pull rod is slidably connected between adjacent extrusion components. A second spring is connected to both the front and rear sides of the pull rod and an adjacent extrusion component. The pull rod is slidably connected to an adjacent push plate and a third spring is connected to an adjacent extrusion component. The mating plate moves upward, causing the sliding plate to move upward along the rotating column. Under the action of the threaded groove on the rotating column, the rotating column rotates. Rotating the upper threaded groove causes the second sliding frame to move the pressing plate downwards, cooperating with the hot pressing plate to press the upper part of the bamboo material. When the connecting plate moves upwards, it drives the extrusion component to move upwards. The extrusion component moves upwards and compresses with the pushing component, causing the connecting plates on the left and right sides to approach each other and connect with the hot pressing plate. Under the action of the hot pressing plate, the connecting plates of the front and rear parts close together, pressing the left and right ends of the bamboo material. When the connecting plate connects with the hot pressing plate, it causes the pull rod to compress the third spring. When the connecting plate closes and presses the bamboo material, it compresses the second spring through the pull rod. The third spring and the second spring are used to assist the connecting plate in resetting.

[0009] Furthermore, it also includes a glue removal mechanism for scraping off excess glue from bamboo raw materials. The glue removal mechanism includes a first mounting frame, a scraper, and a fourth spring. The first mounting frame is connected to the left side of the drying balance processor. The first mounting frame and the right side of the stationary frame are both slidably connected to scrapers. Each scraper is connected to multiple fourth springs between it and the adjacent first mounting frame and stationary frame. The scrapers move close to each other to scrape off excess glue from the bamboo raw materials after glue impregnation.

[0010] Furthermore, it also includes an extrusion mechanism that ejects bamboo material adhered to the hot press plate. The extrusion mechanism includes a support frame, a rotating plate, a first torsion spring, an extruder, and a second torsion spring. Multiple support frames are connected to the upper right side of the base. Rotating plates are rotatably connected to the upper front and rear sides of the support frames. First torsion springs are connected to the adjacent support frames on both sides of the rotating plates. Extruders are rotatably connected to the lower left and right sides of the hot press plate. The extruders are pressed against the adjacent rotating plates. Second torsion springs are connected to the adjacent hot press plates on both sides of the extruders. The extruders move upward with the hot press plate, pressing the rotating plates and causing them to rotate. After passing the rotating plates, the hot press plate closes. When the hot press plate returns to its lower position, the rotating plates rotate in one direction, pressing the extruders and causing them to rotate. This lifts the hot-pressed and shaped bamboo material adhered to the hot press plate for easy handling. The hot press plate continues to return to its lower position until the extruders detach from the rotating plates. Under the rebound of the first and second torsion springs, the extruders and rotating plates rotate and return to their original positions.

[0011] Furthermore, it also includes a heat dissipation mechanism to accelerate the cooling and shaping of bamboo. The heat dissipation mechanism includes a second mounting frame and nozzles. The second mounting frame is connected to the right side of the first sliding frame that is far apart from each other. The nozzles are connected to the second mounting frame. The nozzles deliver air to the bamboo raw material for hot pressing and shaping, thereby accelerating the cooling and shaping of bamboo.

[0012] Furthermore, it also includes a dust removal mechanism for cleaning dust from the surface of bamboo raw materials. The dust removal mechanism includes a third mounting frame, brushes, servo motors, and transmission components. The third mounting frame is connected to the left side of the first sliding frame and the upper left side of the base. Brushes are rotatably connected to both the front and rear parts of the third mounting frame. A servo motor is connected to the rear part of the third mounting frame. The output shaft of the servo motor is connected to the adjacent brushes. A transmission component is connected between the adjacent brushes. The transmission component includes pulleys and belts. Pulleys are connected to the brushes. Belts are wound between adjacent pulleys. The rotation of the servo motor output shaft drives the brushes to rotate through the transmission component. The rotation of the brushes cleans the dust from the surface of the bamboo raw materials.

[0013] Furthermore, it also includes the following steps:

[0014] S1: Bamboo is treated for corrosion and mildew prevention. This is achieved by subjecting one side of the bamboo unit to high-temperature steam sterilization, biological pretreatment, primary steaming, saturated steam carbonization, and secondary steaming to obtain a mildew- and corrosion-resistant bamboo unit. The preparation method of the anti-corrosion and mildew agent is as follows: First, by using boron-based materials and nano-titanium dioxide to replace the commonly used copper salt and alkylammonium compound system, the environmental pollution problem is solved, achieving a green and environmentally friendly effect. Second, by utilizing the blending and film-forming properties of highly water-based molecules and functionalized small molecules, the technical problem of poor coating permeability is solved, achieving pore-curing and mildew prevention in the bamboo substrate. Third, through the strong interaction between polymer materials and functional component molecules, the problem of poor compatibility in conventional bamboo treatment agents is solved.

[0015] S2: The bamboo unit is impregnated with glue. The resulting mildew-proof and anti-corrosion bamboo unit is placed on the placement rack. The placement rack is moved by the drive component. The placement rack is controlled to move the bamboo unit into the stationary frame. With the concave structure of the first sliding frame, the bamboo unit enters the stationary frame to be impregnated with glue.

[0016] S3: The bamboo units after impregnation are dried and balanced. The drive component controls the placement rack to move the bamboo units after impregnation into the drying and balancing processor for drying and balancing.

[0017] S4: The bamboo unit after drying and balancing is pressed and shaped. The drive assembly controls the placement frame to move the bamboo unit after drying and balancing to the position of the hot press plate. The hot press plate is lifted upward by a multi-stage hydraulic cylinder. The cooperation of the rotating plate and the guide rod, and the connection plate control the hot press plates to move closer to each other to clamp and press the bamboo. The sliding plate drives the rotating column to rotate, so that the second sliding frame drives the pressing plate to move downward to press the top of the bamboo. Under the action of the hot press plate, the connecting plates of the front and rear parts close together to press the left and right ends of the bamboo raw material. After the bamboo unit cools down, a high weather-resistant bamboo reconstituted material is obtained.

[0018] The present invention has the following advantages: 1. The present invention controls the placement frame to move by driving the bamboo unit to perform impregnation and hot pressing to form a one-stop structure, which can facilitate the preparation of high weather-resistant reconstituted bamboo, avoid repeated handling of bamboo, and improve the preparation efficiency of high weather-resistant reconstituted bamboo.

[0019] 2. This invention uses scrapers that come close together to scrape off excess adhesive from bamboo raw materials after impregnation, thus avoiding waste caused by excessive adhesive residue on bamboo units.

[0020] 3. The present invention uses a rotating plate to squeeze the extruded part, causing the extruded part to rotate and lift the hot-pressed bamboo material that is adhered to the hot press plate. This operation can achieve the effect of pushing out the bamboo material that is adhered to the hot press plate, making it easier to transport and remove the highly weather-resistant reconstituted bamboo.

[0021] 4. This invention uses nozzles to heat-press and shape bamboo raw materials by supplying air, which accelerates the cooling and shaping of bamboo, thereby achieving the effect of accelerating the cooling and shaping of bamboo and improving the efficiency of preparing high weather-resistant reconstituted bamboo.

[0022] 5. The present invention cleans the surface dust of bamboo raw materials by rotating a brush, which can achieve the effect of cleaning bamboo units before impregnation and improving the quality of bamboo preparation. Attached Figure Description

Detailed Implementation

[0038] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0039] An apparatus and method for preparing highly weather-resistant reconstituted bamboo, such as Figure 1 and Figure 2 As shown, it includes a base 1, a stationary frame 2, a drying balance processor 3, a feeding mechanism 4, and a hot pressing mechanism 5. The stationary frame 2 is connected to the upper left side of the base 1, the drying balance processor 3 is connected to the upper right side of the base 1, the feeding mechanism 4 is provided on the top of the base 1, and the hot pressing mechanism 5 is provided on the upper right side of the base 1.

[0040] like Figures 1-4As shown, the feeding mechanism 4 includes a first sliding frame 41, a drive assembly 42, a sliding block 43, and a placement frame 44. The first sliding frame 41 is connected to the upper sides of both the front and rear parts of the base 1. The drive assembly 42 is connected to the first sliding frame 41 at the front. The sliding block 43 is slidably connected to the right side of the first sliding frame 41. The drive assembly 42 includes a motor and a lead screw. The motor is connected to the first sliding frame 41 at the front. The lead screw is connected to the output shaft of the motor. The lead screw is rotatably connected to the first sliding frame 41. The lead screw is threadedly connected to the adjacent sliding block 43. The placement frame 44 is slidably connected to the upper part of the sliding block 43. The placement frame 44 is slidably connected to the first sliding frame 41. The left side of the first sliding frame 41 near the stationary frame 2 has a recessed structure, so that when the placement frame 44 moves above the stationary frame 2, it will slide down on the sliding block 43, driving the bamboo raw material into the stationary frame 2 for bamboo raw material impregnation treatment.

[0041] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the hot pressing mechanism 5 includes a multi-stage hydraulic cylinder 51, a hot pressing plate 52, a guide rod 53, a rotating disk 531, a connecting plate 54, a docking plate 55, a rotating column 56, a sliding plate 57, a moving plate 58, a second sliding frame 59, a pressing plate 510, a first spring 511, a pushing plate 512, an extrusion piece 513, a pull rod 514, a second spring 515, and a third spring 516. The multi-stage hydraulic cylinder 51 is connected to the upper right side of the base 1. The multi-stage hydraulic cylinder 51 has extension and retraction ends at both the front and rear ends. A sliding connection is provided with a hot press plate 52. Two guide rods 53 are connected to the upper right of the base 1, each with a threaded groove. Connecting plates 54 are rotatably connected to the lower left and right sides of the hot press plate 52. A rotating disk 531 is connected between the bottoms of adjacent connecting plates 54, and each rotating disk 531 is slidably connected to the adjacent guide rod 53. A mating plate 55 is slidably connected to the left and right sides of the hot press plate 52. Four rotating columns 56 are rotatably connected to the right side of the base 1. The rotating columns 56 are positioned vertically and horizontally. Both parts are also provided with threaded grooves. A sliding plate 57 is slidably connected to the lower part of each rotating column 56. A moving plate 58 is slidably connected to the upper part of each sliding plate 57. The top of each moving plate 58 is slidably connected to an adjacent mating plate 55. A second sliding frame 59 is slidably connected to the upper part of each rotating column 56. A pressure plate 510 is slidably connected to the second sliding frame 59. A first spring 511 is connected to the upper sides of both sides of the pressure plate 510 between it and the second sliding frame 59. The upper part of the base 1 is connected to... Two push plates 512 and two lower parts of the mating plate 55 are connected to extrusion parts 513. The extrusion parts 513 are in extrusion fit with the adjacent push plates 512. The adjacent extrusion parts 513 are slidably connected to the pull rods 514. The front and rear parts of the pull rods 514 are connected to the adjacent extrusion parts 513 with second springs 515. The pull rods 514 are slidably connected to the adjacent push plates 512. The pull rods 514 are connected to the adjacent extrusion parts 513 with third springs 516.

[0042] In use, the obtained anti-mildew and anti-corrosion bamboo unit is first placed on the placement rack 44. The drive assembly 42 moves the placement rack 44 to move the bamboo unit into the stationary frame 2. The left side of the first sliding frame 41, near the stationary frame 2, has a recessed structure, so when the placement rack 44 moves above the stationary frame 2, it slides down on the sliding block 43, bringing the bamboo raw material into the stationary frame 2 for resin impregnation. Then, the drive assembly 42 controls the placement rack 44 to move the resin-impregnated bamboo unit into the drying and balancing processor 3 for drying and balancing. After the drying and balancing process is completed, the drive assembly 42 controls the placement rack 44 to move the bamboo unit to the position of the hot press plate 52. Multi-stage hydraulic cylinder 51 pushes hot press plate 52 upward to clamp bamboo units on placement rack 44. As hot press plate 52 moves upward, it drives rotating disk 531 upward via connecting plate 54. Guided by the threaded groove on guide rod 53, rotating disk 531 pulls hot press plate 52 closer together to clamp the bamboo raw material. Furthermore, as hot press plate 52 moves upward or approaches each other, it drives mating plate 55 to move upward. The upward movement of mating plate 55 drives sliding plate 57 upward via moving plate 58. Sliding plate 57 slides upward along rotating column 56, rotating under the action of threaded groove on rotating column 56. The column 56 rotates, and the rotating upper threaded groove of the column 56 causes the second sliding frame 59 to move the pressing plate 510 downward, cooperating with the hot pressing plate 52 to press the upper part of the bamboo material. When the connecting plate 55 moves upward, it drives the extrusion member 513 to move upward. The extrusion member 513 moves upward and compresses with the pushing member, causing the connecting plates 55 on the left and right sides to come closer together and connect with the hot pressing plate 52. Under the action of the hot pressing plate 52, the front and rear connecting plates 55 close together, pressing the left and right ends of the bamboo material. When the connecting plate 55 connects with the hot pressing plate 52, it causes the pull rod 514 to compress the third spring 516. And when the connecting plate 55 closes to press the bamboo material, it compresses the second spring 515 through the pull rod 514. The third spring 516 and the second spring 515 are used to assist the docking plate 55 in resetting. After hot pressing, the extension end of the multi-stage hydraulic cylinder 51 moves downward, causing the hot pressing plate 52 to reset downward. The rotating disk 531 also resets downward and rotates, causing the hot pressing plates 52 to move away from each other and no longer clamp the bamboo unit. The resetting of the hot pressing plate 52 will drive the docking plate 55 to reset together. After the resetting is completed, the obtained high weather-resistant reconstituted bamboo can be taken out from the repeated placement rack 44. The placement rack 44 is moved by the drive component 42 to drive the bamboo unit to undergo glue impregnation and hot pressing to form a one-stop structure operation, which can facilitate the preparation of high weather-resistant reconstituted bamboo, avoid repeated handling of bamboo, and improve the preparation efficiency of high weather-resistant reconstituted bamboo.

[0043] like Figure 2 and Figure 9 As shown, it also includes a degumming mechanism 6, which includes a first mounting bracket 61, a scraper 62 and a fourth spring 63. The first mounting bracket 61 is connected to the left side of the drying balance processor 3. The first mounting bracket 61 and the right side of the stationary frame 2 are both slidably connected to the scraper 62. Each scraper 62 is connected to two fourth springs 63 between it and the adjacent first mounting bracket 61 and stationary frame 2.

[0044] Using the glue removal mechanism 6 of the present invention, excess glue on the bamboo raw material can be scraped off. When the placement rack 44 transports the bamboo unit after glue impregnation, the scrapers 62 move close to each other to scrape off excess glue on the bamboo raw material after glue impregnation, thus avoiding excessive glue residue on the bamboo unit. By scraping off excess glue on the bamboo raw material after glue impregnation by moving close to each other, the effect of scraping off excess glue on the bamboo raw material can be achieved, thus avoiding excessive glue residue on the bamboo unit and causing waste.

[0045] like Figure 1 , Figure 2 , Figure 10 , Figure 11 and Figure 12 As shown, it also includes an extrusion mechanism 7, which includes a support frame 71, a rotating plate 72, a first torsion spring 73, an extruder 74, and a second torsion spring 75. Two support frames 71 are connected to the upper right side of the base 1. The upper front and rear sides of the support frame 71 are rotatably connected to the rotating plate 72. The left and right sides of the rotating plate 72 are connected to the adjacent support frame 71 with the first torsion spring 73. The lower left and right sides of the hot press plate 52 are rotatably connected to the extruder 74. The extruder 74 is pressed and engaged with the adjacent rotating plate 72. The left and right sides of the extruder 74 are connected to the adjacent hot press plate 52 with the second torsion spring 75.

[0046] Using the extrusion mechanism 7 of the present invention, bamboo material adhered to the hot press plate 52 can be ejected. The extruded part 74 moves upward with the hot press plate 52, squeezing the rotating plate 72 and causing the rotating plate 72 to rotate. After passing the rotating plate 72, the hot press plate 52 closes. When the hot press plate 52 returns to its original position downward, since the rotating plate 72 rotates in one direction, it squeezes the extruded part 74, causing the extruded part 74 to rotate. This lifts the hot-pressed and shaped bamboo material adhered to the hot press plate 52 for easy handling. As the hot press plate 52 continues to reset downwards, until the extruder 74 disengages from the rotating plate 72, the extruder 74 and the rotating plate 72 rotate and reset under the action of the first torsion spring 73 and the second torsion spring 75. The rotating plate 72 squeezes the extruder 74, causing it to rotate and lift the hot-pressed bamboo material that is adhered to the hot press plate 52. This operation can push out the bamboo material that is adhered to the hot press plate 52, making it easier to transport and remove the highly weather-resistant reconstituted bamboo.

[0047] like Figure 1 , Figure 2 and Figure 13 As shown, it also includes a heat dissipation mechanism 8, which includes a second mounting bracket 81 and a nozzle 82. The second mounting bracket 81 is connected to the right side of the first sliding bracket 41 that is far apart from each other, and the nozzle 82 is connected to the second mounting bracket 81.

[0048] Using the heat dissipation mechanism 8 of the present invention, the cooling and molding of bamboo can be accelerated. Through the external air guiding device of the nozzle 82, the gas enters the nozzle 82 and is ejected through the nozzle 82. The nozzle 82 heat-pressing and shaping causes air to be delivered to the bamboo raw material, thereby accelerating the cooling and molding of bamboo. By using the nozzle 82 heat-pressing and shaping to deliver air to the bamboo raw material, the cooling and molding of bamboo can be accelerated, thereby achieving the effect of accelerating the cooling and molding of bamboo and improving the efficiency of preparing high weather-resistant reconstituted bamboo.

[0049] like Figure 1 , Figure 2 and Figure 14 As shown, it also includes a dust removal mechanism 9, which includes a third mounting bracket 91, a brush 92, a servo motor 93, and a transmission assembly 94. The third mounting bracket 91 is connected to the left side of the first sliding bracket 41 and the upper left side of the base 1. The brush 92 is rotatably connected to both the front and rear parts of the third mounting bracket 91. The servo motor 93 is connected to the rear part of the third mounting bracket 91. The output shaft of the servo motor 93 is connected to the adjacent brush 92. The transmission assembly 94 is connected between the adjacent brushes 92. The transmission assembly 94 includes a pulley and a belt. The brush 92 is connected to a pulley, and a belt is wound between the adjacent pulleys.

[0050] Using the cleaning mechanism 9 of the present invention, the bamboo unit can be cleaned before impregnation with glue. The output shaft of the servo motor 93 rotates and drives the brush 92 to rotate through the transmission component 94. The brush 92 rotates to clean the dust on the surface of the bamboo raw material. By cleaning the dust on the surface of the bamboo raw material by rotating the brush 92, the bamboo unit can be cleaned before impregnation with glue, thereby improving the quality of bamboo preparation.

[0051] like Figures 1-14 As shown, it also includes the following steps:

[0052] S1: Bamboo is treated for corrosion and mildew prevention. This is achieved by subjecting one side of the bamboo unit to high-temperature steam sterilization, biological pretreatment, primary steaming, saturated steam carbonization, and secondary steaming to obtain a mildew- and corrosion-resistant bamboo unit. The preparation method of the anti-corrosion and mildew agent is as follows: First, by using boron-based materials and nano-titanium dioxide to replace the commonly used copper salt and alkylammonium compound system, the environmental pollution problem is solved, achieving a green and environmentally friendly effect. Second, by utilizing the blending and film-forming properties of highly water-based molecules and functionalized small molecules, the technical problem of poor coating permeability is solved, achieving pore-curing and mildew prevention in the bamboo substrate. Third, through the strong interaction between polymer materials and functional component molecules, the problem of poor compatibility in conventional bamboo treatment agents is solved.

[0053] S2: The bamboo unit is impregnated with glue. The resulting mildew-proof and anti-corrosion bamboo unit is placed on the placement rack 44. The placement rack 44 is moved by the drive component 42. The placement rack 44 is controlled to move the bamboo unit into the stationary frame 2. With the concave structure of the first sliding frame 41, the bamboo unit enters the stationary frame 2 to be impregnated with glue.
