Description

Technical Field

[0001] This invention relates to the field of bamboo processing technology, specifically to an automated bamboo bundle weaving and reconstituted bamboo preparation device and method. Background Technology

[0002] Reconstituted bamboo (also known as reconstituted bamboo) is a high-performance bamboo composite material made from bamboo through processes such as decomposition, drying, impregnation, assembly, and hot pressing. It has excellent properties such as high strength, good dimensional stability, corrosion resistance, and mildew resistance. It has broad application prospects in building structural materials, indoor and outdoor flooring, furniture, and decorative materials, and has been included in the latest catalog of typical "bamboo-based plastic" products.

[0003] However, traditional reconstituted bamboo manufacturing processes have significant limitations: each process is separate, resulting in low production efficiency, high labor intensity for workers, and easy waste of raw materials during transportation. In addition, reconstituted bamboo products for different purposes (such as wall panel decoration materials, flooring, etc.) have different requirements for material density. In traditional production processes, the process parameters are adjusted manually based on experience to achieve the target density, which is complicated and difficult to guarantee accuracy. At the same time, the manual assembly method not only limits the size of reconstituted bamboo, but also makes the density control process cumbersome. The cumulative loss rate of small-format boards is significantly higher than that of large-format boards when preparing the final product in subsequent processes such as edge trimming, slicing, and width determination, resulting in low raw material utilization. Summary of the Invention

[0004] The purpose of this invention is to provide an automated bamboo bundle weaving and preparation device and method for reconstituted bamboo, addressing the significant limitations of traditional reconstituted bamboo manufacturing processes mentioned in the background: each process is independent, resulting in low production efficiency, high labor intensity for workers, and easy waste of raw materials during transportation. Furthermore, different applications of reconstituted bamboo products (such as wall panel decoration materials, flooring, etc.) have different requirements for material density. Traditional production processes rely on manual experience to adjust process parameters to achieve the target density, which is complex and difficult to guarantee accuracy. Simultaneously, the reliance on manual assembly not only limits the size of the reconstituted bamboo but also makes density control cumbersome. The cumulative loss rate of small-format bamboo sheets during subsequent edge trimming, slicing, and width determination processes is significantly higher than that of large-format sheets. This solution addresses the problem of low raw material utilization by enabling fully automated operation. It allows for coordinated and centralized processing of various steps, facilitating large-scale production, reducing costs, and increasing efficiency. The elimination of excessive transport reduces losses during transit. Fully automated production eliminates the need for users to adjust process parameters based on experience or perform excessive manual operations, significantly simplifying the user's workflow, reducing workload and operational difficulty, improving precision, controlling the size of reconstituted bamboo as needed, minimizing bamboo loss, and increasing raw material utilization. Furthermore, the device can adjust the density of products according to their intended use, reducing production limitations and expanding its application range.

[0013] Automated method for preparing reconstituted bamboo by bamboo bundle weaving:

[0014] Step 1: Thinning and drying. Place bamboo strips with a thickness of four to eight millimeters on the first conveyor belt and thin them through the thinning machine to obtain thinned bamboo bundles. Then, transport them through the first conveyor belt to one end of the second conveyor belt and then through the second conveyor belt for further transport. The bamboo bundles are then dried and cooled through the dryer to adjust them to the required moisture content.

[0015] Step Two: Grouping. The user controls the width of the bamboo bundles using the first motor, first threaded rod, first slider, and positioning sensor. The user controls the tilting direction of the layering frame and the third conveyor belt using the first electric push rod and the first connecting rod to facilitate loading and unloading. After the first electric push rod extends, the bamboo bundles are loaded via the third conveyor belt until they move to the position obtained by the positioning sensor. Then, the bamboo bundles are unloaded. The first electric push rod shortens, so that the bottom end of one side of the third conveyor belt is higher than the height of the bamboo bundles on the surface of the second conveyor belt. The bamboo bundles are moved onto the bamboo bundles on the surface of the second conveyor belt via the third conveyor belt. At the same time, the second conveyor belt continues to transport the bamboo bundles. At this point, the bamboo bundle stacking work is completed, making the bamboo bundle layer thicker.

[0016] Step 3: Weaving. The thickened bamboo bundles are moved to one side of the weaving frame by the second conveyor belt. The feeding frame and feeding needles automatically feed the bamboo bundles intermittently. During weaving, the pressure plate can press the bamboo bundles that have moved to one end of the support. The top plate and hook needles move up and down, and together with the thread plate and thread block, the weaving is finally achieved, and the single bamboo bundles are woven into a whole.

[0017] Step 4: Stacking. The bamboo bundles are counted by an infrared counting sensor. When the required number of bamboo bundles is reached, the cutter cuts the threads. The fourth motor and the second threaded rod drive the moving plate and the placement plate to move, so that the bamboo bundles can be laid flat on the surface of the placement plate. After one layer is laid, the fifth motor and the third threaded rod can move the placement plate down to facilitate the subsequent laying of bamboo bundles. The speed of the third conveyor belt can control the density of the woven bamboo bundles. Combined with the infrared counting sensor and the cutter to control the number of layers of bamboo bundles, the density of the reconstituted bamboo can be controlled.

[0018] Step 5: Impregnation. After the bamboo bundles are laid flat inside the material cage, they are placed inside the impregnation tank for impregnation, and then transported by the fourth conveyor belt.

[0019] Step Six: Secondary drying, using a dryer for drying;

[0020] Step 7: Shaping. Finally, the bamboo is hot-pressed to obtain reconstituted bamboo. After trimming and fine planing, the final product is obtained.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The user places bamboo strips, 4 to 8 millimeters thick, onto the first conveyor belt. These strips are then separated by a splitting machine to obtain split bamboo bundles. These bundles are then conveyed via the first conveyor belt to one end of the second conveyor belt, where they are further transported. A dryer dries and cools the bundles, adjusting their moisture content to a suitable level. The bundles are then grouped into upper and lower groups by an automatic grouping mechanism. The tilting direction of the layering frame and the third conveyor belt is controlled by a first electric push rod and a first connecting rod, causing a set of first limit rods and limit blocks to abut against each other, thus limiting the feeding. The extension of the first electric push rod allows the bamboo bundles at the top of the second conveyor belt to move through one end of the third conveyor belt to the top of the layering frame. The user controls the movement via a first motor, a first threaded rod, a first slider, and a positioning sensor. When the positioning sensor detects a bamboo bundle, the first electric push rod shortens, resetting the layering frame until another set of first limit rods contacts another set of limit blocks, completing the positioning for unloading. At this point, the bottom end of one side of the third conveyor belt is higher than the height of the bamboo bundles on the surface of the second conveyor belt. The third conveyor belt then moves the bamboo bundles onto the surface of the second conveyor belt, while the second conveyor belt continues to transport the bamboo bundles, completing the stacking of the bamboo bundles and thickening the bamboo bundle layer. Once all the bamboo bundles on the surface of the layering frame have been unloaded, the first electric push rod again controls one end of the layering frame to move downwards, repeating the loading and unloading process. This continuous automatic layering and stacking ensures the thickness of the bamboo bundles. Because the stacking of bamboo bundles creates gaps between the two sets of bamboo bundle layers, this process is repeated. The gap serves as a folding point between the two layers of bamboo bundles during stacking. The length of the bamboo strips determines the length of the reconstituted bamboo, and the length of the woven bamboo bundle determines the width of the reconstituted bamboo. The length of the woven bamboo bundle is determined by a positioning sensor installed on the layering frame. The second conveyor belt moves the bamboo bundle layer to one end of the weaving frame. The user inserts the thread spool onto the thread rod, so that one end of the thread bundle passes through the thread hole and wraps around the hook groove at the top of the crochet hook, leaving one end of the thread on the weaving frame for automatic weaving. When the second conveyor belt moves the bamboo bundle to the bottom of the thread frame, the second motor starts working. The working second motor causes the first and third gears to rotate through the second gear and toothed belt. The first gear drives the rotating rod to rotate through the transmission rod, and the rotating rod drives one end of the fifth connecting rod to perform a circular motion. The other end of the fifth connecting rod is restricted in its movement trajectory by the second limiting rod. At this time, the connection between the second limiting rod and the fifth connecting rod is in an arc-shaped movement trajectory. The top rod allows the feeding frame and feeding needle to move in an elliptical movement trajectory, thus enabling the feeding frame and feeding needle to move upwards and forwards, thereby achieving intermittent movement of the bamboo bundle. Simultaneously, one end of a set of second limiting rods drives the fourth and second connecting rods to reciprocate, causing the pressure rod and pressure plate to reciprocate in an arc shape. This causes the pressure plate to continuously press down and lift, thus pressing the bamboo bundle that has moved to one end of the support member. When the feeding frame and feeding needle move upwards, the pressure plate lifts, facilitating the movement of the bamboo bundle. The third gear drives the turntable to rotate.The turntable and the sixth connecting rod cause the top plate and hook to move back and forth continuously. The first telescopic rod ensures that the movement of the top plate and hook remains vertical. When the bamboo bundle moves to one end of the support, the upward-moving hook passes through the support and the bamboo bundle. As the top plate moves the hook downward, it pulls the ball, the eighth connecting rod, and the inclined block downward. The inclined block and the inclined groove allow the reciprocating block and the seventh connecting rod to rotate. The rotating seventh connecting rod causes the thread plate and the thread hole to move, thus bringing the single strand of thread into contact with the tip of the hook, thereby... As the hook pulls the single strand of yarn, when the hook groove at the tip of the hook moves to the single strand of yarn, the hook pulls the single strand of yarn downwards through the hook groove and the protruding rod. Since one end of the yarn is on the braiding frame, when the yarn pulled by the hook passes through the support, the yarn is in two strands. When the hook pulls the two strands of yarn between the slide plates, the third motor, which is now working, moves the slide plate and the yarn block through the reciprocating screw and the reciprocating slider. This causes the yarn block to pull the two strands of yarn through the groove, forming two separate strands of yarn. At this point, the two strands of yarn are in two strands of yarn. The hook is moved to one end of the block, then to the bottom of the block. The hook then moves upwards, passing between the two strands of thread on one side of the block. The upward movement of the hook causes the two strands of thread on one side of the block to separate, leaving them at opposite ends of the hook. The movement of the bamboo bundle tightens the two strands at the bottom. When the two strands of thread move to the middle of the bamboo bundle with the hook, the single strand of thread comes into contact with the hook through the thread board. The hook then moves the single strand of thread downwards, passing between the separated two strands. At this point, the single strand of thread and the double strand of thread are connected. Located in the middle of the bamboo bundle, a knot is formed, and through continuous operation, the bamboo bundles are braided together, connecting individual bamboo pieces into a single unit. The bamboo bundles are continuously conveyed by a feeding frame and feeding needles, moving them to one end of an inclined conveyor belt. As the bamboo bundles pass through the gantry frame, an infrared counting sensor on one side of the gantry counts the number of bundles. When the required quantity is reached, an electric slider drives a cutter to cut the fibers. For example, to prepare a 3 cm thick bundle with a density of 1.1... Reconstituted bamboo with a density of g / cm³ requires seven layers of woven bamboo bundles. After the seventh woven bamboo bundle passes through, a cutter separates the woven threads. Combined with the limiting mold of the hot press, the thickness and density of the reconstituted bamboo are controlled. The fourth motor and the second threaded rod drive the moving plate and the placement plate to move, allowing the bamboo bundles to be laid flat on the surface of the placement plate. After one layer is laid, the fifth motor and the third threaded rod move the placement plate down, facilitating the subsequent laying of bamboo bundles. During stacking, the bamboo bundles are stacked in a "Z" shape. By controlling the speed of the third conveyor belt on the layering rack, the density of the woven bamboo bundles can be controlled. Combined with the above layer control, the density of the reconstituted bamboo can be controlled, which is very simple and convenient. After the flattened bamboo bundles are placed inside the material cage, they are placed in the impregnation tank for impregnation, and then transported by the fourth conveyor belt.Reconstituted bamboo is produced by drying in a dryer and then hot-pressing in a hot press. This fully automated system allows for coordinated operation of each process, facilitating large-scale production, reducing costs, and increasing efficiency. It eliminates the need for excessive handling, minimizing losses during transport. The fully automated process eliminates the need for user-based parameter adjustments and manual operation, significantly simplifying the workflow, reducing workload and difficulty, improving precision, controlling the size of the reconstituted bamboo as needed, reducing material waste, and increasing raw material utilization. Furthermore, the system can adjust the density of the bamboo according to different applications, reducing production limitations and expanding its range of uses. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-13 One embodiment provided by the present invention:

[0039] An automated bamboo bundle braiding and reconstituted bamboo preparation device and preparation method are disclosed. The device includes a first conveyor belt 1, a second conveyor belt 3 at one end of the first conveyor belt 1, an automatic grouping mechanism for automatic grouping and layering at the middle of the second conveyor belt 3, a braiding mechanism for automatic bamboo bundle braiding at one end of the second conveyor belt 3, and an automatic stacking mechanism at one end of the braiding mechanism.

[0040] Please see Figures 1-3In this embodiment, the automatic grouping mechanism includes a support plate 5. Support plates 5 are symmetrically arranged in the middle of the second conveyor belt 3. A layered frame 6, connected to the support plate 5 via bearings, is provided at the top of the second conveyor belt 3. Third conveyor belts 7 are provided at both ends of the layered frame 6. A first electric push rod 9 is connected to the middle of a set of support plates 5 via a rotating shaft. The output end of the first electric push rod 9 is connected to a first connecting rod 8 via a rotating shaft, and one end of the first connecting rod 8 is connected to one end of the support plate 5 via a rotating shaft. An adjustment groove 10 is provided at one end of the support plate 5. A first motor 11 is provided at one end of the adjustment groove 10. A first threaded rod 12, connected to the inner wall of the adjustment groove 10 via bearings, is fixedly connected to the output end of the first motor 11. The inner wall of the adjustment groove 10... A first slider 13 is slidably connected to the first threaded rod 12 via a thread. A positioning sensor 14 is provided at one end of the first slider 13. Two sets of limiting blocks 15 are fixedly connected to one side of a set of support plates 5. Two sets of first limiting rods 16 are fixedly connected to one end of the layering frame 6, and each of the first limiting rods 16 corresponds to a limiting block 15. The bamboo bundles are grouped by an automatic grouping mechanism, dividing the bamboo bundles into upper and lower groups. The output end of the first electric push rod 9 drives the first connecting rod 8 to move. The first connecting rod 8 controls the tilting direction of the layering frame 6 and the third conveyor belt 7. A set of first limiting rods 16 and limiting blocks 15 on the side closer to the dryer 4 abut against each other, completing the limiting of the feeding. After the third conveyor belt 7 starts working, the second conveyor belt 3 tops... The bamboo bundle at one end is moved to the top of the layering rack 6 via the third conveyor belt 7. The user controls the first threaded rod 12 to rotate via the first motor 11, and controls the first slider 13 and positioning sensor 14 to move via the first threaded rod 12. Thus, the width of the bamboo bundle is controlled by the first motor 11, the first threaded rod 12, the first slider 13, and the positioning sensor 14. The user moves the positioning sensor 14 to the desired position. When the positioning sensor 14 detects the bamboo bundle, the first electric push rod 9 shortens, controlling the layering rack 6 to reset until another set of first limit rods 16 abuts against another set of limit blocks 15. At this point, the positioning of the unloading is completed. At this time, the bottom end of one side of the third conveyor belt 7 is higher than the height of the bamboo bundle on the surface of the second conveyor belt 3. Then, the bamboo bundle is moved through the third conveyor belt 7. The conveyor belt 7 moves the bamboo bundles onto the surface of the second conveyor belt 3, while the second conveyor belt 3 continues to convey the bamboo bundles. At this time, the stacking of the bamboo bundles is completed, making the bamboo bundle layer thicker. After all the bamboo bundles on the surface of the layering frame 6 are unloaded, the first electric push rod 9 controls one end of the layering frame 6 to move down again, and the loading and unloading work is carried out again. At this time, the automatic layering and stacking work is continuously carried out to ensure the thickness of the bamboo bundles. Since the stacking of bamboo bundles will create gaps between the two sets of bamboo bundle layers, the function of these gaps is to serve as the fold lines between the two layers of bamboo bundles when stacking. The length of the bamboo strips can determine the length of the reconstituted bamboo, and the length of the woven bamboo bundles can determine the width of the reconstituted bamboo. The length of the woven bamboo bundles is determined by the positioning sensor 14 set on the layering frame 6, which can automatically perform layering and length determination.

One end of each third gear 42 is fixedly connected to a turntable 43. One end of each sixth connecting rod 44 is connected to the edge of the turntable 43 via a pivot. Hooks 45 are evenly fixedly connected to the top of the top plate 40, and each hook 45 is located in the middle of a grooved plate at one end of the support member 39. Each hook 45 has a hook groove 46 at its top, and protruding rods are evenly fixedly connected to the inner wall of the top of the hook groove 46. A through groove 47 is symmetrically opened on the top of each hook 45, and the through grooves 47 are located at the top of the hook groove 46. A wire plate 48 is provided at the top of the braided frame 17, and the wire plate 48 is located at the top of the pressure plate 80. One side of the top plate 40 has evenly spaced thread holes 49 corresponding to the hook 45. Both ends of the thread plate 48 are connected to a seventh connecting rod 50 via a pivot. The bottom end of each seventh connecting rod 50 is connected to the knitting frame 17 via a pivot and fixedly connected to the reciprocating block 51. The reciprocating block 51 is located at both ends of the top plate 40. Inclined grooves 52 are formed inside each reciprocating block 51, and inclined blocks 53 are slidably connected inside each groove 52. Both ends of the top plate 40 are rotatably connected to spheres 54. One end of each inclined block 53 is fixedly connected to an eighth connecting rod 55, which is also fixedly connected to the sphere 54. A first fixing rod 56 is provided at the top of the knitting frame 17. Fixing plates 57 are evenly fixedly connected to one side of the first fixing rod 56, and each fixing plate 57 corresponds to a hook 45. The internal components of each slide plate 58 are slidably connected to a slide plate 58. One end of each slide plate 58 is fixedly connected to a reciprocating slider 59. The reciprocating slider 59 is internally connected to a reciprocating lead screw 61 via a reciprocating crescent-shaped thread. A third motor 60, fixedly connected to the reciprocating lead screw 61, is installed inside each fixed plate 57. A line block 62 is symmetrically arranged at one end of each slide plate 58. A second fixing rod 63, fixedly connected to the slide plate 58, is installed inside each line block 62. A torsion spring 64 is installed inside each line block 62, with both ends fixedly connected to the second fixing rod 63 and the line block 62, respectively. One end of each line block 62 is in contact with the slide plate 58. Crochet hooks 45 are located at the center of one end of each slide plate 58. The control terminals of the third motor 60 are electrically connected to an external power source.The upward and forward movements of the feeding frame 37 and the feeding needle 38 intermittently move the bamboo bundle. Simultaneously, one end of a set of second limiting rods 33 drives the fourth connecting rod 26 and the second connecting rod 25 to reciprocate, causing the pressure rod 24 and the pressure plate 80 to reciprocate in an arc shape. This causes the pressure plate 80 to continuously press down and lift, thus pressing the bamboo bundle that has moved to one end of the support member 39. When the feeding frame 37 and the feeding needle 38 move upward, the pressure plate 80 lifts, facilitating the movement of the bamboo bundle. The third gear 42 drives the turntable 43 to rotate. Through the turntable 43 and the sixth connecting rod 44, the top plate 40 and the hook 45 continuously reciprocate up and down. The first telescopic rod 41 ensures... The top plate 40 and hook 45 always move in a vertical position. When the bamboo bundle moves to one end of the support 39, the upward-moving hook 45 passes through the support 39 and the bamboo bundle. When the top plate 40 drives the hook 45 to move downward, the top plate 40 pulls the ball 54, the eighth connecting rod 55, and the inclined block 53 downward. The inclined surface of the inclined block 53 abuts against the inclined surface of the inclined groove 52, which allows the reciprocating block 51 and the seventh connecting rod 50 to rotate. At the same time, the reciprocating block 51 drives the eighth connecting rod 55 and the ball 54 to rotate through the inclined block 53. The ball 54 rotates at both ends of the top plate 40. The rotating seventh connecting rod 50 causes the line plate 48 and the line hole 49 to move, so that the single strand of thread abuts against the top of the hook 45, which facilitates the subsequent movement of the single strand of thread by the hook 45. When the hook groove 46 at the top of the lower hook 45 moves to the single strand of thread, the lower hook 45 pulls the single strand of thread downward through the hook groove 46 and the protruding rod. Since one end of the thread is on the braiding frame 17, when the thread pulled by the hook 45 passes through the support 39, the thread is in two strands. When the hook 45 pulls the two strands of thread to the space between the slide plates 58, the third motor 60, which is working at this time, moves the slide plates 58 and the line block 62 through the reciprocating lead screw 61 and the reciprocating slider 59, so that the line block 62 pulls the two strands of thread through the through groove 47 to move, forming two separate strands of thread. At this time, the two strands of thread are at one end of the line block 62. Then the hook 45 moves to the bottom of the line block 62, and then the hook 45 moves upward, passing through the space between the two strands of thread on one side of the line block 62. The upward-moving hook 45 causes the two strands of thread on one side of the line block 62 to separate. At this time, the two strands of thread are located at the two ends of the hook 45 respectively. Under the action of moving the bamboo bundle, the two strands of thread at its bottom end tighten. When the two strands of thread move with the hook 45 to the middle of the bamboo bundle, the single strand of thread comes into contact with the hook 45 through the line plate 48. At this time, the hook 45 drives the single strand of thread to move down, and the single strand of thread passes between the separated two strands of thread. At this time, the connection point of the single strand of thread and the double strand of thread is in the middle of the bamboo bundle, thus forming a knot. By continuously working in this way, the bamboo bundle can be braided together, so that the single bamboo bundles are braided into a whole. After the bamboo bundle passes through the gantry frame 20, the electric slider 21 drives the cutter 22 to work, and the cutter 22 cuts the thread.This facilitates the automatic weaving process of this device;

[0044] Please see Figure 13 In this embodiment, the stacking mechanism includes an inclined conveyor belt 65. One end of the braided frame 17 is provided with the inclined conveyor belt 65, and one end of the inclined conveyor belt 65 is provided with a positioning base plate 66. One end of the positioning base plate 66 is provided with a fourth motor 67.

A movable plate 69 is slidably connected to the top of the positioning base plate 66, and the bottom end of the movable plate 69 is connected to the second threaded rod 68 via a thread. A placement plate 70 is provided at the top of the movable plate 69. Both ends of the movable plate 69 are symmetrically and fixedly connected with second telescopic rods 71 ​​fixedly connected to the placement plate 70. A threaded sleeve 72 is provided in the middle of the bottom end of the placement plate 70, and the bottom end of the threaded sleeve 72 is connected to a third threaded rod 74 via a thread. A fifth motor 73, which is fixedly connected to the third threaded rod 74, is fixedly connected to the middle of the moving plate 69. The control ends of the inclined conveyor belt 65, the fourth motor 67, and the fifth motor 73 are all electrically connected to an external power source. The bamboo bundles are continuously conveyed by the feeding rack 37 and the feeding needle 38, so that they move to one end of the inclined conveyor belt 65 and are then conveyed by the inclined conveyor belt 65. The output end of the fourth motor 67 can move the moving plate 69 and the placement plate 70 through the second threaded rod 68. The bamboo bundles can be laid flat on the surface of the placement plate 70 by the moving placement plate 70. After one layer is laid, the placement plate 70 can be moved down by the fifth motor 73 and the third threaded rod 74, so that subsequent bamboo bundles can be laid flat again, which facilitates the automatic stacking work of this device.

[0045] It should be noted that a loosening machine 2 is installed in the middle of the first conveyor belt 1, a dryer 4 is installed at one end of the second conveyor belt 3, a material cage 75 is installed at one end of the stacking mechanism, an impregnation tank 76 is installed at one end of the material cage 75, a fourth conveyor belt 77 is installed at one end of the impregnation tank 76, a dryer 78 is installed in the middle of the fourth conveyor belt 77, and a hot press 79 is installed at one end of the fourth conveyor belt 77. The control terminals of the first conveyor belt 1, loosening machine 2, second conveyor belt 3, dryer 4, material cage 75, impregnation tank 76, fourth conveyor belt 77, dryer 78, and hot press 79 are all electrically connected to an external power source to facilitate the operation of subsequent processes. The bottoms of both ends of the layering frame 6 are sloped, and the sides of the layering frame 6 that are close to each other are also sloped to facilitate the movement of bamboo bundles. The control terminals of the third conveyor belt 7, the first electric push rod 9, the first motor 11, and the positioning sensor 14 are all electrically connected to an external power source through an external switch to facilitate the automatic operation of this device.

[0046] Automated method for preparing reconstituted bamboo by bamboo bundle weaving:

[0047] Step 1: Thinning and drying. Place bamboo strips with a thickness of four to eight millimeters on the first conveyor belt 1 and thin them through the thinning machine 2 to obtain thinned bamboo bundles. Then, convey them through the first conveyor belt 1 to one end of the second conveyor belt 3 and convey them through the second conveyor belt 3 again. Dry and cool them through the dryer 4 and adjust the bamboo bundles to the required moisture content through the dryer 4.

[0048] Step 2: Grouping. The user controls the width of the bamboo bundle through the first motor 11, the first threaded rod 12, the first slider 13, and the positioning sensor 14. The user controls the tilting direction of the layering frame 6 and the third conveyor belt 7 through the first electric push rod 9 and the first connecting rod 8 to facilitate loading and unloading. After the first electric push rod 9 extends, the bamboo bundle is loaded through the third conveyor belt 7 until it moves to the position obtained by the positioning sensor 14. Then, the bamboo bundle is unloaded. The first electric push rod 9 shortens so that the bottom end of one side of the third conveyor belt 7 is higher than the height of the bamboo bundle on the surface of the second conveyor belt 3. The bamboo bundle is moved onto the bamboo bundle on the surface of the second conveyor belt 3 through the third conveyor belt 7. At the same time, the second conveyor belt 3 continues to transport the bamboo bundle. At this time, the bamboo bundle stacking work is completed, making the bamboo bundle layer thicker.

[0049] Step 3: Weaving. The thickened bamboo bundles are moved to one side of the weaving frame 17 by the second conveyor belt 3. The feeding frame 37 and feeding needle 38 automatically feed the bamboo bundles intermittently. During weaving, the pressure plate 80 can press the bamboo bundles that have moved to one end of the support 39. The top plate 40 and hook 45 move up and down, and together with the thread plate 48 and thread block 62, the weaving is finally achieved, and the single bamboo bundles are woven into a whole.

[0050] Step 4: Stacking. The infrared counting sensor 81 counts the bamboo bundles. When the required number of bamboo bundles is reached, the cutter 22 cuts the threads. The fourth motor 67 and the second threaded rod 68 drive the moving plate 69 and the placement plate 70 to move, so that the bamboo bundles can be laid flat on the surface of the placement plate 70. After one layer is laid, the fifth motor 73 and the third threaded rod 74 can move the placement plate 70 down to facilitate the subsequent laying of bamboo bundles. The speed of the third conveyor belt 7 can control the density of the woven bamboo bundles. The infrared counting sensor 81 and the cutter 22 control the number of layers of bamboo bundles, thereby controlling the density of the reconstituted bamboo.

[0051] Step 5: Impregnation. After the bamboo bundles are laid flat inside the material cage 75, they are placed inside the impregnation tank 76 for impregnation, and then transported by the fourth conveyor belt 77.

[0052] Step Six: Secondary drying, using dryer 78 for drying;

[0053] Step 7: Shaping. Finally, the bamboo is hot-pressed using a hot press 79 to obtain reconstituted bamboo. After trimming and fine planing, the final product is obtained.

[0054] Working principle: The user places bamboo strips with a thickness of four to eight millimeters on the first conveyor belt 1, which are then loosened by the loosening machine 2 to obtain loosened bamboo bundles. These bundles are then conveyed by the first conveyor belt 1 to one end of the second conveyor belt 3, where they are further conveyed and dried by the dryer 4. The dryer 4 adjusts the bamboo bundles to a suitable moisture content. The bamboo bundles are then grouped by an automatic grouping mechanism, separating them into upper and lower groups. The output end of the first electric push rod 9 drives the first connecting rod 8 to move, controlling the tilt direction of the layering frame 6 and the third conveyor belt 7. A set of first limiting rods 16 and limiting blocks 15 near the dryer 4 abut against each other, limiting the feeding. After the third conveyor belt 7 starts working, the bamboo bundles at the top of the second conveyor belt 3 are... The third conveyor belt 7 moves to the top of the layering rack 6. The user controls the first threaded rod 12 to rotate via the first motor 11, and controls the first slider 13 and positioning sensor 14 to move via the first threaded rod 12. Thus, the width of the bamboo bundle is controlled by the first motor 11, the first threaded rod 12, the first slider 13, and the positioning sensor 14. The user moves the positioning sensor 14 to the desired position. When the positioning sensor 14 detects the bamboo bundle, the first electric push rod 9 shortens, controlling the layering rack 6 to reset until another set of first limit rods 16 abuts against another set of limit blocks 15. At this point, the positioning for unloading is completed. At this time, the bottom end of one side of the third conveyor belt 7 is higher than the height of the bamboo bundle on the surface of the second conveyor belt 3. Then, the bamboo bundle is moved to the surface of the second conveyor belt 3 by the third conveyor belt 7. On the bamboo bundles, the second conveyor belt 3 continues to transport the bamboo bundles, completing the stacking of the bamboo bundles and thickening the bamboo bundle layer. After all the bamboo bundles on the surface of the layering frame 6 have been unloaded, the first electric push rod 9 controls one end of the layering frame 6 to move down again, performing loading and unloading operations again. At this time, automatic layering and stacking work is continuously performed to ensure the thickness of the bamboo bundles. Since the stacking of bamboo bundles will create gaps between the two sets of bamboo bundle layers, the function of these gaps is to serve as the fold lines between the two layers of bamboo bundles during stacking. The length of the bamboo strips determines the length of the reconstituted bamboo, and the length of the woven bamboo bundles determines the width of the reconstituted bamboo. The length of the woven bamboo bundles is determined by the positioning sensor 14 installed on the layering frame 6. The second conveyor belt 3 can move the bamboo bundle layer to one end of the braiding frame 17, where the user inserts the wire spool into the wire rod 1. On the 9th, one end of the wire bundle passes through the wire hole 49 and wraps around the hook groove 46 at the top of the hook 45, leaving one end of the wire on the braiding frame 17 for automatic weaving. When the second conveyor belt 3 moves the bamboo bundle to the bottom of the wire frame 18, the second motor 34 starts working. The output end of the second motor 34 drives the second gear 35 to rotate. The rotating second gear 35 causes the first gear 29 and the third gear 42 to rotate through the toothed belt 36. The first gear 29 drives the rotating rod 30 to rotate through the transmission rod 28. The rotating rod 30 drives one end of the fifth connecting rod 31 to perform a circular motion. At the same time, the other end of the fifth connecting rod 31 is restricted in its movement trajectory by the second limiting rod 33. At this time, the connection between the second limiting rod 33 and the fifth connecting rod 31 is in an arc-shaped movement trajectory.At this time, the top rod 32 enables the feeding frame 37 and the feeding needle 38 to move in an elliptical trajectory, thus allowing the feeding frame 37 and the feeding needle 38 to move upward and forward, thereby achieving intermittent movement of the bamboo bundle. Simultaneously, one end of a set of second limiting rods 33 drives the fourth connecting rod 26 and the second connecting rod 25 to reciprocate, causing the pressure rod 24 and the pressure plate 80 to reciprocate in an arc shape, causing the pressure plate 80 to continuously press down and lift. The pressure plate 80 can press the bamboo bundle that has moved to one end of the support member 39. When the feeding frame 37 and the feeding needle 38 move upward, the pressure plate 80 lifts, facilitating the movement of the bamboo bundle. The third gear 42 drives the turntable 43 to rotate, and through the turntable 43 and the sixth connecting rod 4... 4. This causes the top plate 40 and hook 45 to continuously move up and down. The first telescopic rod 41 ensures that the movement of the top plate 40 and hook 45 remains vertical. When the bamboo bundle moves to one end of the support member 39, the upward-moving hook 45 passes through the support member 39 and the bamboo bundle. When the top plate 40 moves the hook 45 downward, it pulls the ball 54, the eighth connecting rod 55, and the inclined block 53 downward. The inclined surface of the inclined block 53 abuts against the inclined surface of the inclined groove 52, causing the reciprocating block 51 and the seventh connecting rod 50 to rotate. At the same time, the reciprocating block 51 drives the eighth connecting rod 55 and the ball 54 to rotate through the inclined block 53. The ball 54 rotates at both ends of the top plate 40. The rotating seventh connecting rod 50 causes the line plate 48 and the line hole 49 to move, thereby making... The single strand of yarn abuts against the tip of the hook 45, facilitating the subsequent movement of the single strand of yarn by the hook 45. When the hook groove 46 at the tip of the hook 45 moves to the single strand of yarn, the hook 45 pulls the single strand of yarn downward through the hook groove 46 and the protruding rod. Since one end of the yarn is on the braiding frame 17, when the yarn pulled by the hook 45 passes through the support 39, the yarn is in two strands. When the hook 45 pulls the two strands of yarn to the space between the slide plates 58, the third motor 60, which is working at this time, moves the slide plates 58 and the line block 62 through the reciprocating screw 61 and the reciprocating slider 59, causing the line block 62 to pull the two strands of yarn through the through groove 47, forming two separate strands of yarn. At this time, the two strands of yarn are at one end of the line block 62, and then the hook 45 moves to... At the bottom of line block 62, hook 45 moves upward, passing between the two strands of thread on one side of line block 62. The upward movement of hook 45 causes the two strands of thread on one side of line block 62 to separate. At this time, the two strands of thread are located at opposite ends of hook 45. Under the action of moving the bamboo bundle, the two strands of thread at its bottom end tighten. When the two strands of thread move with hook 45 to the middle of the bamboo bundle, the single strand of thread comes into contact with hook 45 through the thread plate 48. At this time, hook 45 drives the single strand of thread to move downward, allowing the single strand of thread to pass between the separated two strands of thread. At this time, the connection point of the single strand of thread and the double strand of thread is in the middle of the bamboo bundle, thus forming a knot. By continuously working in this way, the bamboo bundle can be braided together, so that the single bamboo bundles are braided into a whole. When the bamboo bundle passes through the gantry frame 20,At this time, the infrared counting sensor 81 on one side of the gantry frame 20 counts the bamboo bundles. When the required quantity is reached, the electric slider 21 drives the cutter 22 to cut the fibers. For example, to prepare a 3 cm thick bundle with a density of 1.1 g / cm³, 3 The reconstituted bamboo requires seven layers of woven bamboo bundles. After the seventh woven bamboo bundle passes through, the woven threads are cut by a cutter 22. Combined with the limiting mold of the hot press 79, the thickness and density of the reconstituted bamboo are controlled. The bamboo bundles are continuously conveyed by the feeding rack 37 and feeding needle 38, moving them to one end of the inclined conveyor belt 65. The inclined conveyor belt 65 then conveys them. The output end of the fourth motor 67, through the second threaded rod 68, enables the moving plate 69 and the placement plate 70 to move. The moving placement plate 70 allows the bamboo bundles to be laid flat on its surface. After one layer is laid, the fifth motor 73 and the third threaded rod 74 move the placement plate 70 downward, facilitating the subsequent laying of bamboo bundles. During stacking, the bamboo bundles are stacked in a "Z" shape. By controlling the speed of the third conveyor belt 7 on the layering rack 6, the density of the woven bamboo bundles can be controlled. Combined with the above-mentioned layer control, the density of the reconstituted bamboo can be controlled, which is very simple and convenient. After the bamboo bundles are laid flat inside the material cage 75, they are placed inside the impregnation tank 76 for impregnation with resin. Then, they are conveyed by the fourth conveyor belt 77, dried by the dryer 78, and finally hot-pressed by the hot press 79 to obtain reconstituted bamboo. This device can operate fully automatically, allowing each process to cooperate and work together, facilitating large-scale production, reducing production costs, and improving production efficiency. It also reduces losses during transportation by eliminating the need for excessive transfer. Through fully automated production, users do not need to adjust process parameters based on experience or perform excessive operations, which not only greatly simplifies the user's operation process but also reduces the user's workload and operational difficulty, improves precision, and allows for control of the size of the reconstituted bamboo according to needs. It also reduces bamboo loss and improves raw material utilization. At the same time, this device can also adjust the density of the product according to different uses, reducing production limitations and expanding the scope of application.

7. A method for preparing an automated bamboo bundle braiding and reconstituted bamboo apparatus as described in claim 6, characterized in that: Step 1: Thinning and drying. Place bamboo strips with a thickness of four to eight millimeters on the first conveyor belt (1) and thin them through the thinning machine (2) to obtain thinned bamboo bundles. Then, convey them through the first conveyor belt (1) to one end of the second conveyor belt (3) and convey them through the second conveyor belt (3) again. Dry them and cool them through the dryer (4) to adjust the bamboo bundles to the required moisture content. Step 2: Grouping. The user controls the width of the bamboo bundle through the first motor (11), the first threaded rod (12), the first slider (13) and the positioning sensor (14), and controls the tilting direction of the layering frame (6) and the third conveyor belt (7) through the first electric push rod (9) and the first connecting rod (8) to facilitate loading and unloading. After the first electric push rod (9) extends, it loads the bamboo bundle through the third conveyor belt (7) until the bamboo bundle moves to the position obtained by the positioning sensor (14), and then unloads the bamboo bundle. The first electric push rod (9) shortens so that the bottom of one side of the third conveyor belt (7) is higher than the height of the bamboo bundle on the surface of the second conveyor belt (3). The bamboo bundle is moved to the bamboo bundle on the surface of the second conveyor belt (3) through the third conveyor belt (7), while the second conveyor belt (3) continues to transport the bamboo bundle. At this time, the bamboo bundle stacking work is completed, making the bamboo bundle layer thicker. Step 3: Weaving.

During weaving, the pressure plate (80) can press the bamboo bundles that have moved to one end of the support (39). The top plate (40) and hook (45) move up and down, and with the help of the thread plate (48) and thread block (62), weaving is finally achieved, and the single bamboo bundles are woven into a whole. Step 4: Stacking. The count is performed by the infrared counting sensor (81). When the bamboo bundles reach the required quantity, the cutter (22) cuts the threads. The fourth motor (67) and the second threaded rod (68) drive the moving plate (69) and the placement plate (70) to move, so that the bamboo bundles can be laid flat on the surface of the placement plate (70). After one layer is laid, the fifth motor (73) and the third threaded rod (74) can move the placement plate (70) down, so that the subsequent bamboo bundles can be laid flat again. The speed of the third conveyor belt (7) can control the density of the woven bamboo bundles. The infrared counting sensor (81) and the cutter (22) control the number of layers of bamboo bundles, and thus control the density of the reconstituted bamboo. Step 5: Impregnation. After the bamboo bundles are laid flat inside the material cage (75), they are impregnated inside the impregnation tank (76) and then transported by the fourth conveyor belt (77). Step 6: Secondary drying, using a dryer (78) for drying; Step 7: Shaping. Finally, the bamboo is hot-pressed by a hot press (79) to obtain reconstituted bamboo. After trimming and fine planing, the final product is obtained.
