Description

Technical Field

[0001] This invention relates to the field of reconstituted bamboo production technology, and more specifically, to an intelligent reconstituted bamboo production system and method. Background Technology

[0002] Reconstituted bamboo, also known as resilient bamboo, is a new bamboo material that is reorganized and strengthened. It involves processing bamboo into long strips, shreds, or crushed bundles, drying them, impregnating them with resin, drying them again to the required moisture content, and then laying them in a mold for high-temperature, high-pressure thermosetting to form profiles. Currently, in the production process of reconstituted bamboo, bamboo strips are generally simply screened visually, without any screening of the bamboo mats (woven from processed bamboo strips). After being cut, the bamboo mats enter the cold-pressing and shaping process. The quality of the bamboo mats directly affects the quality of the finished product. However, the bamboo mats are only cut according to their length. Although the cut bamboo mats appear to be similar in size, their actual quality varies, sometimes significantly, making standardized production of the boards difficult. If weighing is only done after the final hot-pressing, the large number of boards makes weighing and sorting extremely time-consuming and labor-intensive, resulting in losses. Automated weighing and sorting during the production process, along with intelligent manufacturing, would greatly benefit the industry's development. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an intelligent production system and method for reconstituted bamboo, which can automatically weigh bamboo curtains and automatically remove bamboo curtains that do not meet the weight requirements, so that the weighing and screening of bamboo curtains and the transportation and production of bamboo curtains are not interfered with each other, thus optimizing the production process of reconstituted bamboo and improving product quality.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A reconstituted bamboo intelligent production system includes a panel weaving module, a weighing module, a cold pressing and shaping module, a hot pressing module, and a panel output module. The panel weaving module weaves bamboo strips into bamboo curtains and cuts the bamboo curtains. The panel weaving module is connected to the cold pressing and shaping device module through the weighing module. The hot pressing module is connected to the cold pressing and shaping module through a conveyor belt. The panel output module is located behind the hot pressing module and removes the hot-pressed panels.

[0006] The weighing module includes a first conveyor belt, a weighing device, and a second conveyor belt. The first conveyor belt is connected to the board weaving module, and the second conveyor belt is connected to the cold pressing and shaping module. The weighing device includes a weighing roller conveyor and a temporary storage mechanism. The weighing roller conveyor is located between the first and second conveyor belts. First detection sensors are respectively installed at the front and rear ends of the weighing roller conveyor. The length of the weighing roller conveyor is greater than or equal to the length of the bamboo curtain. A first transverse gap is provided between the weighing roller conveyors to cooperate with the temporary storage mechanism. The temporary storage mechanism includes a first lifting mechanism and a multi-layer temporary storage grid. Two sets of first lifting mechanisms are respectively installed on the left and right sides of the weighing roller conveyor. The multi-layer temporary storage grid is installed from bottom to top between the two sets of first lifting mechanisms. The multi-layer temporary storage grid is controlled by the first lifting mechanism to freely move up and down through the first transverse gap of the temporary storage mechanism.

[0007] In one embodiment, the temporary storage mechanism is also equipped with an early warning device.

[0008] In one embodiment, the weighing module further includes an auxiliary storage device, which includes a transport roller conveyor and a storage mechanism. The transport roller conveyor is located between the weighing roller conveyor and the second transport belt. Second detection sensors are respectively installed at the front and rear ends of the transport roller conveyor. The length of the transport roller conveyor is greater than or equal to the length of the bamboo curtain. A second lateral gap is provided between the transport roller conveyors to cooperate with the storage mechanism. The storage mechanism includes a second lifting mechanism and a multi-layer storage grid. Two sets of second lifting mechanisms are respectively installed on the left and right sides of the transport roller conveyor. The multi-layer storage grid is installed from bottom to top between the two sets of second lifting mechanisms. The multi-layer storage grid is controlled by the second lifting mechanism to freely move up and down through the second lateral gap of the storage mechanism.

[0009] In one embodiment, the outlet of the panel weaving module is provided with an outlet conveyor belt and a fixed-length sawing mechanism. The outlet conveyor belt is located between the outlet of the panel weaving module and a first conveyor belt, and the fixed-length sawing mechanism is located between the outlet conveyor belt and the panel weaving module to saw the completed woven long bamboo curtain into bamboo curtains of a specific length according to the specification requirements.

[0010] The fixed-length sawing mechanism includes a clamping device and a sawing device. The clamping device is located above the discharge conveyor belt and the board weaving module, and the sawing device is located below the discharge conveyor belt and the board weaving module.

[0011] In one embodiment, the discharge conveyor belt is equipped with a weight sensor to measure the weight of the bamboo curtain after sawing.

[0012] In one embodiment, the board unloading module includes an automatic unloading robot and a vision recognition device. The vision recognition device detects the thickness and gloss of the board, while the automatic unloading robot realizes automatic unloading and automatic stacking of the board.

[0013] A method for intelligent production of reconstituted bamboo, comprising the following steps:

[0014] Bamboo strips are continuously placed on the panel weaving module, which weaves the bamboo strips into a bamboo curtain. The panel weaving module then cuts the continuous bamboo curtain to the required length.

[0015] After being cut, the bamboo curtains enter the first conveyor belt, which then sends them onto the weighing roller conveyor. When only one bamboo curtain remains on the weighing roller conveyor, the first conveyor belt, the weighing roller conveyor, and the second conveyor belt stop, preventing subsequent bamboo curtains from entering the weighing roller conveyor. The weighing roller conveyor monitors the weight of the bamboo curtains in real time.

[0016] When the weight of the bamboo curtain is detected to be outside the preset weight range, the first lifting mechanism drives the temporary storage grid to rise, lifting the bamboo curtain away from the weighing roller conveyor. Then the first conveyor belt and the weighing roller conveyor start first, so that the next bamboo curtain enters the weighing roller conveyor.

[0017] When the weight of the bamboo curtain is detected to be within the preset weight range, the first conveyor belt, the weighing roller conveyor, and the second conveyor belt are restarted to transport the qualified bamboo curtain away from the weighing roller conveyor and allow the next bamboo curtain to enter the weighing roller conveyor. The qualified bamboo curtains then enter the cold pressing and shaping module and the hot pressing module in sequence to be pressed and shaped, and finally the unloading device completes the unloading.

[0018] In one embodiment, when an auxiliary storage device is provided, the method is as follows:

[0019] After being cut, the bamboo curtains enter the first conveyor belt, which then sends them onto the weighing roller conveyor. When only one bamboo curtain remains on the weighing roller conveyor, the first conveyor belt, the weighing roller conveyor, the transport roller conveyor, and the second conveyor belt stop, preventing subsequent bamboo curtains from entering the weighing roller conveyor. The weighing roller conveyor monitors the weight of the bamboo curtains in real time.

[0020] When the weight of the bamboo curtain is detected to be higher than the preset weight range, the first lifting mechanism drives the temporary storage grid to rise, lifting the bamboo curtain away from the weighing roller conveyor. Then the first conveyor belt and the weighing roller conveyor start first, so that the next bamboo curtain enters the weighing roller conveyor.

[0021] When the weight of the bamboo curtain is detected to be lower than the preset weight range, the first conveyor belt, weighing roller and transport roller start first, the next bamboo curtain fully enters the weighing roller for weighing, at the same time, the bamboo curtain that is too light leaves the weighing roller and fully enters the transport roller. Then the first conveyor belt, weighing roller and transport roller, the weighing roller weigh the bamboo curtain above, at the same time, the second lifting mechanism drives the storage grid to rise, lifting the bamboo curtain that is too light away from the transport roller.

[0022] When the weight of the bamboo curtain is detected to be within the preset weight range, the first conveyor belt, weighing roller, transport roller and second conveyor belt are restarted. The bamboo curtain that meets the requirements is transported away from the weighing roller and transport roller and enters the second conveyor belt. The next bamboo curtain enters the weighing roller. The bamboo curtain that meets the requirements then enters the cold pressing and shaping module and the hot pressing module in sequence to be pressed and shaped. Finally, the material is unloaded by the board unloading device.

[0023] In one embodiment, a preset weight range for the bamboo curtain is set using a weight sensor on the discharge conveyor belt, as follows:

[0024] Collect the weight data of the first 3-5 bamboo curtains after sawing, take the average weight data, and use this average value as a baseline with a positive or negative fluctuation of 1-5% as the weight range for the weighing roller to measure the bamboo curtains.

[0025] In summary, the present invention has the following beneficial effects:

[0026] This invention can automatically weigh bamboo curtains and automatically remove bamboo curtains that do not meet the weight requirements, so that the weighing and screening of bamboo curtains and the transportation and production of bamboo curtains do not interfere with each other, thus optimizing the production process of reconstituted bamboo and improving product quality.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.

[0034] A recombinant bamboo intelligent production system, such as Figure 1-3 As shown, it includes a panel weaving module 1, a weighing module 2, a cold pressing and shaping module 3, a hot pressing module 4, and a panel output module 5. The panel weaving module 1 weaves bamboo strips into bamboo curtains and cuts the bamboo curtains. The panel weaving module 1 is connected to the cold pressing and shaping device module through the weighing module 2. The hot pressing module 4 is connected to the cold pressing and shaping module 3 through a conveyor belt. The panel output module 5 is located behind the hot pressing module 4 and removes the hot-pressed panels.

[0035] The weighing module 2 includes a first conveyor belt 201, a weighing device, and a second conveyor belt 202. The first conveyor belt 201 is connected to the board weaving module 1, and the second conveyor belt 202 is connected to the cold pressing and shaping module 3. The weighing device includes a weighing roller conveyor 203 and a temporary storage mechanism. The weighing roller conveyor 203 is located between the first conveyor belt 201 and the second conveyor belt 202. First detection sensors are respectively installed at the front and rear ends of the weighing roller conveyor 203. The length of the weighing roller conveyor 203 is greater than or equal to the length of the bamboo curtain. A first transverse gap is provided between the weighing roller conveyors 203 to cooperate with the temporary storage mechanism. The temporary storage mechanism includes a first lifting mechanism 205 and a multi-layer temporary storage grid 204. Two sets of first lifting mechanisms 205 are respectively installed on the left and right sides of the weighing roller conveyor 203. The multi-layer temporary storage grid 204 is installed from bottom to top between the two sets of first lifting mechanisms 205. The multi-layer temporary storage grid 204 is controlled by the first lifting mechanism 205 to freely move up and down through the first transverse gap of the temporary storage mechanism.

[0036] The weighing roller conveyor 203 is powered by itself and can transport the bamboo curtain into and out of the roller conveyor. The weighing sensor is set at the bottom of the weighing roller conveyor 203. When the bamboo curtain is completely above the weighing roller conveyor 203, the weighing sensor can detect the weight change of the weighing roller conveyor 203, thereby detecting the weight of the bamboo curtain.

[0037] When weighing the bamboo curtain, only one bamboo curtain is allowed to stay on the weighing roller 203. That is, the weighing roller 203 will only measure and record the bamboo curtain above when the first detection sensor at the front end detects that the next bamboo curtain has completely entered the weighing roller 203 and the first detection sensor at the rear end does not detect the bamboo curtain.

[0038] In this invention, the weighing module 2 can weigh the passing bamboo curtains and remove those that do not meet the requirements from the production line. The specific production method of this invention is as follows:

[0039] Bamboo strips are continuously placed on the panel weaving module 1, which weaves the bamboo strips into a bamboo curtain. The panel weaving module 1 then cuts the continuous bamboo curtain to the required length.

[0040] After being cut, the bamboo curtain enters the first conveyor belt 201, and then the first conveyor belt 201 sends the bamboo curtain onto the weighing roller conveyor 203. When only one bamboo curtain remains on the weighing roller conveyor 203, the first conveyor belt 201, the weighing roller conveyor 203 and the second conveyor belt 202 stop, restricting the subsequent bamboo curtains from entering the weighing roller conveyor 203. The weighing roller conveyor 203 detects the weight of the bamboo curtain in real time.

[0041] When the weight of the bamboo curtain is detected to be outside the preset weight range, the first lifting mechanism 205 drives the temporary storage grid 204 to rise, lifting the bamboo curtain away from the weighing roller conveyor 203. Then the first conveyor belt 201 and the weighing roller conveyor 203 start first, so that the next bamboo curtain enters the weighing roller conveyor 203.

[0042] When the weight of the bamboo curtain is detected to be within the preset weight range, the first conveyor belt 201, the weighing roller 203 and the second conveyor belt 202 are restarted to transport the qualified bamboo curtain away from the weighing roller 203 and allow the next bamboo curtain to enter the weighing roller 203. The qualified bamboo curtains then enter the cold pressing and shaping module 3 and the hot pressing module 4 in sequence to be pressed and shaped, and finally the unloading device completes the unloading.

[0043] Furthermore, the temporary storage mechanism is also equipped with an early warning device. When the lowest temporary storage grid 204 rises above the first weighing roller conveyor 203, the early warning device sounds an alarm, and the first conveyor belt 201, the weighing roller conveyor 203 and the second conveyor belt 202 stop, so that the operator can remove all the bamboo curtains on the temporary storage grid 204. After multiple temporary storage grids 204 have descended and reset, the first conveyor belt 201, the weighing roller conveyor 203 and the second conveyor belt 202 are restarted.

[0044] During the weighing process, the entire transport mechanism of the intelligent reconstituted bamboo production system stops. After the weighing is completed, the transport mechanism of the intelligent reconstituted bamboo production system restarts when the weight of the bamboo curtain meets the standard. When the weight of the bamboo curtain does not meet the standard, the transport mechanism located in front of the second transport belt 202 starts first. Only after the bamboo curtain that meets the standard is detected will the entire transport mechanism of the intelligent reconstituted bamboo production system start up again simultaneously to ensure the continuity of production.

[0045] This invention uses a temporary storage mechanism to automatically remove bamboo curtains that do not meet the weight requirements from the production system, ensuring the consistency of the board quality. The temporary storage mechanism, together with the first conveyor belt 201, the weighing roller conveyor 203, and the second conveyor belt 202, enables online weighing and screening during the production process without affecting the continuous production of reconstituted bamboo.

[0046] Furthermore, the weighing module 2 also includes an auxiliary storage device, which includes a transport roller conveyor 206 and a storage mechanism. The transport roller conveyor 206 is located between the weighing roller conveyor 203 and the second transport belt 202. Second detection sensors are respectively installed at the front and rear ends of the transport roller conveyor 206. The length of the transport roller conveyor 206 is greater than or equal to the length of the bamboo curtain. A second transverse gap is provided between the transport roller conveyors 206 to cooperate with the storage mechanism. The storage mechanism includes a second lifting mechanism 207 and a multi-layer storage grid 208. Two sets of second lifting mechanisms 207 are respectively installed on the left and right sides of the transport roller conveyor 206. The multi-layer storage grid 208 is installed from bottom to top between the two sets of second lifting mechanisms 207. The multi-layer storage grid 208 is controlled by the second lifting mechanism 207 to freely rise and fall through the second transverse gap of the storage mechanism.

[0047] The weight inspection of bamboo curtains includes three scenarios: bamboo curtains that are too heavy, bamboo curtains that are too light, and bamboo curtains that meet the weight standard. This invention uses a weighing device and an auxiliary storage device to store excessively heavy or light bamboo curtains separately. The specific method is improved as follows:

[0048] After being cut, the bamboo curtain enters the first conveyor belt 201, which then sends the bamboo curtain onto the weighing roller conveyor 203. When only one bamboo curtain remains on the weighing roller conveyor 203, the first conveyor belt 201, the weighing roller conveyor 203, the transport roller conveyor 206, and the second conveyor belt 202 stop, restricting subsequent bamboo curtains from entering the weighing roller conveyor 203. The weighing roller conveyor 203 monitors the weight of the bamboo curtain in real time.

[0049] When the weight of the bamboo curtain is detected to be higher than the preset weight range, the first lifting mechanism 205 drives the temporary storage grid 204 to rise, lifting the bamboo curtain away from the weighing roller conveyor 203. Then the first conveyor belt 201 and the weighing roller conveyor 203 start first, so that the next bamboo curtain enters the weighing roller conveyor 203.

[0050] When the weight of the bamboo curtain is detected to be lower than the preset weight range, the first conveyor belt 201, weighing roller 203 and transport roller 206 are started first. The next bamboo curtain fully enters the weighing roller 203 for weighing. At the same time, the bamboo curtain that is too light leaves the weighing roller 203 and fully enters the transport roller 206. Then the first conveyor belt 201, weighing roller 203 and transport roller 206, and the weighing roller 203 weigh the bamboo curtain above. At the same time, the second lifting mechanism 207 drives the storage grid 208 to rise, lifting the bamboo curtain that is too light and leaving the transport roller 206.

[0051] When the weight of the bamboo curtain is detected to be within the preset weight range, the first conveyor belt 201, weighing roller 203, transport roller 206 and the second conveyor belt 202 are restarted. The bamboo curtain that meets the requirements is transported away from the weighing roller 203 and transport roller 206 and enters the second conveyor belt 202. The next bamboo curtain enters the weighing roller 203. The bamboo curtain that meets the requirements then enters the cold pressing and shaping module 3 and the hot pressing module 4 in sequence to be pressed and shaped. Finally, the material is unloaded by the board unloading device.

[0052] This invention separates excessively light and excessively heavy bamboo curtains for easy classification and processing. After adjusting the preset weight range for weighing in the next production run, the excessively light or excessively heavy bamboo curtains are put back into production accordingly.

[0053] In this invention, the first lifting mechanism 205 and the second lifting mechanism 207 are both conventional lifting mechanisms, such as cylinder mechanisms, screw lifting mechanisms, etc.

[0054] In this invention, the bamboo weaving module 1 is a conventional bamboo weaving device, which works on a principle similar to a sewing machine, connecting multiple bamboo strips with needle and thread to form a bamboo curtain.

[0055] Furthermore, the outlet of the panel weaving module 1 is equipped with an outlet conveyor belt and a fixed-length sawing mechanism. The outlet conveyor belt is located between the outlet of the panel weaving module 1 and the first conveyor belt 201. The fixed-length sawing mechanism is located between the outlet conveyor belt and the panel weaving module 1 to cut the completed woven long bamboo curtain into bamboo curtains of a specific length according to the specifications.

[0056] The fixed-length sawing mechanism includes a clamping device and a sawing device. The clamping device is positioned above the material conveyor belt and the panel weaving module 1, while the sawing device is positioned below the material conveyor belt and the panel weaving module 1. When sawing is required, the clamping device presses the bamboo curtain downwards, and the sawing device cuts the bamboo curtain. The fixed-length sawing mechanism is a conventional sawing mechanism that uses sensors to measure the length and the clamping device and sawing device to perform the sawing.

[0057] Furthermore, a weight sensor is installed on the discharge conveyor belt to measure the weight of the bamboo curtain after sawing. The weight range of the bamboo curtain can be automatically set by the weight sensor, as follows:

[0058] Collect the weight data of the first 3-5 bamboo curtains after sawing, take the average value of the weight data, and use this average value as a baseline with a positive or negative fluctuation of 1-5% as the weight range for the weighing roller 203 to measure the bamboo curtains.

[0059] For example, assuming the average of the first five bamboo curtain weight data is X, and using this average as a baseline with a ±5% fluctuation, then the weighing roller 203 measures the weight range of the bamboo curtain from 0.95X to 1.05X. Bamboo curtains with a weight below 0.95X are considered too light, while bamboo curtains with a weight above 1.05X are considered too heavy.

[0060] Specifically, when the weighing roller 203 continuously weighs five bamboo curtains and all of them are overweight or underweight, the weight range of the weighing roller 203 for measuring the bamboo curtains is adjusted. The new benchmark is the sum of the weight data of the five bamboo curtains with abnormal weights continuously weighed by the weighing roller 203 and the original benchmark average value X, and the average value X' is taken as the new benchmark. The new benchmark is adjusted by a margin of ±5% to form the new weight range for measuring the bamboo curtains by the weighing roller 203. Moreover, within the same batch of production, the weight range is only adjusted once. After this adjustment, if subsequent continuous weighings of multiple bamboo curtains show that they are overweight or underweight, no further adjustment to the weight range will be made.

[0061] Furthermore, based on the weighing device and auxiliary storage device, this invention can also automatically return bamboo curtains that do not meet the weight requirements to the production line. The specific steps are as follows:

[0062] In the weighing device, the overweight bamboo curtains are stored by the temporary storage grid 204. The weight data of each layer of bamboo curtains on the temporary storage grid 204 is recorded, corresponding to the number of layers of the temporary storage grid 204. When the weighing roller 203 weighs five bamboo curtains consecutively for the first time and all of them are overweight, a new weight range for measurement is automatically set.

[0063] When the weight of the bamboo curtain closest to the weighing roller 203 on the temporary storage grid 204 is within the new weight range, similar to the operation when the temporary storage grid 204 rises, the first conveyor belt 201, the weighing roller 203, the transport roller 206 and the second conveyor belt 202 cooperate. At the same time, the temporary storage grid 204 descends, so that the bamboo curtain closest to the weighing roller 203 returns to the weighing roller 203 and is transported backward.

[0064] Repeat the above operation until the weight of the bamboo curtain closest to the weighing roller 203 on the temporary grid 204 is no longer within the new weight range.

[0065] Similarly, in the auxiliary storage device, the bamboo curtains that are too light are stored by the storage grid 208. The weight data of each layer of bamboo curtains on the storage grid 208 is recorded and corresponds to the number of layers in the storage grid 208. When the weighing roller 203 weighs five bamboo curtains consecutively for the first time and all of them are too light, a new weight range for measurement is automatically set.

[0066] When the weight of the bamboo curtain closest to the transport roller 206 on the storage grid 208 is within the new weight range, similar to the operation when the storage grid 208 rises, the first transport belt 201, the weighing roller 203, the transport roller 206 and the second transport belt 202 cooperate. At the same time, the storage grid 208 descends, so that the bamboo curtain closest to the transport roller 206 returns to the transport roller 206 and is transported backward.

[0067] Repeat the above operation until the weight of the bamboo curtain on the storage grid 208 closest to the transport roller 206 is no longer within the new weight range.

[0068] In addition, since the weight data of the bamboo curtains on the temporary storage grid 204 and the storage grid 208 are recorded, during other batches of production, when the weight of the bamboo curtain closest to the weighing roller 203 on the temporary storage grid 204 or the weight of the bamboo curtain closest to the transport roller 206 on the storage grid 208 is within the measured weight range, the first transport belt 201, the weighing roller 203, the transport roller 206 and the second transport belt 202 work together to lower the temporary storage grid 204 or the storage grid 208, so that the bamboo curtains that meet the weight requirements are lowered back into the production system.

[0069] Furthermore, the board unloading module 5 includes an automatic unloading robot and a vision recognition device. The vision recognition device detects the thickness and gloss of the board, while the automatic unloading robot realizes automatic unloading and automatic stacking of the board.

When only one bamboo curtain remains on the weighing roller conveyor (203), the first conveyor belt (201), the weighing roller conveyor (203), and the second conveyor belt (202) stop, restricting subsequent bamboo curtains from entering the weighing roller conveyor (203). The weighing roller conveyor (203) detects the weight of the bamboo curtain in real time. When the weight of the bamboo curtain is detected to be outside the preset weight range, the first lifting mechanism (205) drives the temporary storage grid (204) to rise, lifting the bamboo curtain away from the weighing roller conveyor (203). Then the first conveyor belt (201) and the weighing roller conveyor (203) start first, so that the next bamboo curtain enters the weighing roller conveyor (203). When the weight of the bamboo curtain is detected to be within the preset weight range, the first conveyor belt (201), the weighing roller (203), and the second conveyor belt (202) are restarted to transport the qualified bamboo curtain away from the weighing roller (203) and allow the next bamboo curtain to enter the weighing roller (203). The qualified bamboo curtains then enter the cold pressing and shaping module (3) and the hot pressing module (4) in sequence to be pressed and shaped, and finally the unloading is completed through the plate unloading module.

6. The intelligent production method for reconstituted bamboo as described in claim 5, characterized in that, When setting up an auxiliary storage device, the method is as follows: After being cut, the bamboo curtain enters the first conveyor belt (201). The first conveyor belt (201) then sends the bamboo curtain onto the weighing roller conveyor (203). When only one bamboo curtain remains on the weighing roller conveyor (203), the first conveyor belt (201), the weighing roller conveyor (203), the transport roller conveyor (206), and the second conveyor belt (202) stop, restricting subsequent bamboo curtains from entering the weighing roller conveyor (203). The weighing roller conveyor (203) detects the weight of the bamboo curtain in real time. When the weight of the bamboo curtain is detected to be higher than the preset weight range, the first lifting mechanism (205) drives the temporary storage grid (204) to rise, lifting the bamboo curtain away from the weighing roller conveyor (203). Then the first conveyor belt (201) and the weighing roller conveyor (203) start first, so that the next bamboo curtain enters the weighing roller conveyor (203). When the weight of the bamboo curtain is detected to be lower than the preset weight range, the first conveyor belt (201), weighing roller (203) and transport roller (206) are started first. The next bamboo curtain is fully entered into the weighing roller (203) for weighing. At the same time, the bamboo curtain that is too light leaves the weighing roller (203) and fully enters the transport roller (206). Then the first conveyor belt (201), weighing roller (203) and transport roller (206) stop. The weighing roller (203) weighs the bamboo curtain above. At the same time, the second lifting mechanism (207) drives the storage grid (208) to rise, lifting the bamboo curtain that is too light away from the transport roller (206). When the weight of the bamboo curtain is detected to be within the preset weight range, the first conveyor belt (201), weighing roller (203), transport roller (206) and second conveyor belt (202) are restarted to transport the bamboo curtain that meets the requirements away from the weighing roller (203) and transport roller (206) and into the second conveyor belt (202), and the next bamboo curtain enters the weighing roller (203). The bamboo curtain that meets the requirements then enters the cold pressing and shaping module (3) and the hot pressing module (4) in sequence to be pressed and shaped, and finally the unloading is completed by the plate unloading module.

7. The intelligent production method for reconstituted bamboo as described in claim 5, characterized in that, The preset weight range of the bamboo curtain is set using a weight sensor on the discharge conveyor belt, as follows: The weight data of the first 3-5 bamboo curtains after sawing are statistically analyzed. The average value of the weight data is taken as the benchmark, and the weight range of the bamboo curtains is determined by a positive or negative fluctuation of 1-5% on the weighing roller (203).
