[0035] Preferably, the biomass fiber fabric is obtained by using a method for preparing a biomass fiber fabric with good toughness.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The present invention uses a temperature sensor and a humidity sensor to monitor the temperature and humidity of the biomass fiber raw material in the crushing and drying stages in real time, thereby switching between drying and screening. When the humidity is too high, the controller increases the output of the hot air blower 1 and the hot air blower 2 to speed up the drying speed. When the humidity is close to or reaches a preset value, the controller reduces the output of the hot air blower 1 and the hot air blower 2 to avoid excessive drying and resulting in a decrease in the quality of the biomass fiber raw material. At the same time, the temperature sensor can monitor the temperature change during the drying process to prevent the biomass fiber raw material from being burned or deteriorated due to excessive temperature. In the screening stage, by understanding the humidity state of the raw material, it can be determined whether further drying or adjustment of the screening conditions is required. Through the method of real-time monitoring and dynamic adjustment, the drying and screening processes can be significantly optimized, energy waste and biomass fiber raw material loss can be reduced, and the preparation efficiency of biomass fiber fabrics can be improved. At the same time, since the controller can automatically adjust the operating parameters according to real-time data, the risk of human operating errors can also be reduced, and the safety of production can be improved. Therefore, the problem of how to optimize the drying and screening processes can be solved, thereby improving the preparation efficiency and safety of biomass fiber fabrics.

[0038] 2. The present invention uses a rotating arc baffle, a rotating circular baffle and a rotating screen plate for multiple screening, and unqualified biomass fiber raw materials fall back for re-crushing and screening. The rotating arc baffle, the rotating circular baffle and the rotating screen plate each have different screening functions and characteristics. Working together, they can effectively separate fibers of different sizes and qualities in the raw materials, which helps to reduce the mixing of unqualified fibers, thereby improving the utilization rate of biomass fiber raw materials. During the screening process, unqualified raw materials will be blocked and fall back to the secondary crushing module for re-crushing, and then screened. This process is repeated until the raw materials meet the qualified screening standards. In this way, unqualified raw materials can be fully utilized and the waste of raw materials is reduced. The screening mechanism of the present invention can ensure the consistency of biomass fiber fabrics. Since the raw materials are subjected to multiple screening and re-crushing processes, the final fiber size and quality are more consistent, which helps to reduce the differences and defects of the fabrics in subsequent processing and use. Therefore, it can solve the problem of how to improve the utilization rate of biomass fiber raw materials and ensure the improvement of the consistency of biomass fiber fabrics.

[0039] 3. The present invention crushes the biomass fiber raw material multiple times through the primary crushing module and the secondary crushing module. First, the primary crushing module performs preliminary crushing treatment on the biomass fiber raw material to crush it into smaller particles, which helps to reduce the size of the raw material and facilitates subsequent processing. Then, the secondary crushing module further crushes and refines the raw material that has been initially crushed to ensure that the raw material reaches a smaller particle size and a more uniform particle size distribution. Through multiple crushing treatments, the quality and performance of the biomass fiber fabric can be effectively improved. In addition, multiple crushing treatments can also help solve the storage and transportation problems of the biomass fiber raw material. The smaller particle size makes the biomass fiber raw material easier to stack and compress, reducing the storage space occupied. At the same time, the uniform particle size distribution also improves the fluidity of the biomass fiber raw material, which is convenient for loading and unloading and handling during transportation, helping to reduce storage and transportation costs, and improving the utilization rate and economy of the biomass fiber raw material. Therefore, it can solve the problem of how to improve the quality and performance of the prepared biomass fiber fabric and facilitate the storage and transportation of the biomass fiber raw material.

[0040] 4. The present invention senses the presence of biomass fiber raw materials by installing an infrared sensor, and then starts to prepare biomass fiber fabrics. When the infrared sensor detects the presence of biomass fiber raw materials, it will transmit the detection information to the controller, and the controller controls other power devices to start the preparation of biomass fiber fabrics, ensuring the continuity of production and avoiding production interruptions or delays caused by human factors. Secondly, through automatic control, the present invention significantly saves human resources. In traditional production methods, workers are usually required to manually monitor the entry of raw materials and start the preparation process, which is not only time-consuming and labor-intensive, but also easily affected by human factors. The automation mechanism of the present invention can replace this part of human work, allowing workers to focus on other more valuable tasks, thereby improving overall production efficiency. In addition, automatic control also helps to reduce human operation errors. Human operation is often affected by multiple factors such as experience, skills, fatigue, etc., and is prone to errors or omissions. Infrared sensors and controllers can perform precise and stable operations according to preset procedures and conditions, avoiding the uncertainty caused by human factors. Therefore, it can solve the problem of how to ensure the continuity of production, save human resources, and reduce human operation errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The screening module includes a screening drum 9 installed inside the fixed frame 2, and a servo motor 10 arranged evenly is installed inside the screening drum 9, and a rotating arc baffle 11 is installed at the output end of the servo motor 10, and the output end of the rotating arc baffle 11 is installed inside the screening drum 9, and a guide drum 13 is installed at the bottom of the screening drum 9, and a servo motor 2 14 is installed on one side of the guide drum 13, and a rotating circular baffle 15 is installed at the output end of the servo motor 2 14, and the rotating circular baffle 15 is located inside the guide drum 13;

[0054] A servo motor 3 16 is installed on the top of the screening drum 9, a rotating shaft 17 is installed on the output end of the servo motor 3 16, and the rotating shaft 17 is installed inside the screening drum 9, the rotating shaft 17 is located on the inner side of the rotating arc baffle 11, and a rotating screen plate 18 is installed at the bottom of the rotating shaft 17, a discharging drum 19 is installed on one side of the screening drum 9, and the discharging drum 19 is installed on the top of the biomass fiber raw material processing body 1, and a hot air blower 20 is installed inside the discharging drum 19.

[0055] Further, the fixing frame 2 is used to install and fix key components such as the screening module. The fixing frame 2 provides the necessary stability and strength to ensure the safety and reliability of the screening module during operation. The screening module is responsible for screening the crushed biomass fiber raw materials, separating the fiber raw materials that meet the standards, and screening out the materials that do not meet the standards or are too large, so as to carry out subsequent secondary crushing or other processing. The partition plate 3 is located inside the biomass fiber raw material processing body 1, separating the crushing and drying chamber 4 from the area where the servo motor 21 and the vertical reducer 22 are installed;

[0056] The crushing and drying chamber 4 is the main place for raw material crushing and drying, where the biomass fiber raw materials are crushed into smaller particles and the moisture is removed by hot air for subsequent processing or making into fabrics. The secondary crushing module is responsible for further crushing the biomass fibers crushed by the primary crushing module and the unqualified or oversized biomass fiber raw materials screened out by the screening module to achieve the required particle size or fiber length;

[0057] A ventilation duct 5 is installed on one side of the biomass fiber raw material processing body 1, and a hot air blower 6 is installed inside the ventilation duct 5. One end of the ventilation duct 5 is installed on the back of the biomass fiber raw material processing body 1, which helps to optimize the air flow circulation and temperature distribution during the drying process, improve the drying efficiency and ensure the uniform heat inside the processing body. At the same time, the hot air blower 6 is connected to the controller through an electrical signal, and the operating state of the hot air blower 6 can be accurately controlled by the controller, including starting, stopping and wind speed adjustment, so as to adjust the drying process according to real-time feedback to maintain the optimal working conditions in the crushing and drying chamber 4;

[0058] A temperature sensor 7 and a humidity sensor 8 are installed on the inner wall of the biomass fiber raw material processing body 1. These two sensors are used to monitor the temperature and humidity inside the crushing and drying chamber 4. Because hot air tends to rise, placing the temperature sensor 7 above the humidity sensor 8 can more accurately reflect the temperature distribution inside the drying chamber. The arrangement of the temperature sensor 7 and the humidity sensor 8 can monitor the key environmental parameters inside the crushing and drying chamber 4 in real time and transmit these data to the controller. The controller can automatically adjust the working state of the hot air blower 6 to keep the temperature and humidity in the crushing and drying chamber 4 within an ideal range, which can not only improve the drying efficiency and reduce energy consumption, but also prevent overheating or overhumidification from adversely affecting the quality of biomass fibers, thereby ensuring the quality of the final product;

[0059] The screening drum 9 is the main part of the screening module, which is used to accommodate the biomass fiber raw materials to be screened and provide a closed environment to complete the screening process. The servo motor 10 is evenly arranged inside the screening drum 9, and is responsible for driving the rotating arc baffle 11, thereby changing the rotation angle of the rotating arc baffle 11 and adjusting the distance between the rotating arc baffles 11. When the distance between the rotating arc baffles 11 is adjusted to be larger, larger-sized biomass fibers are allowed to pass through. If finer screening is required, the servo motor 10 can adjust the rotating arc baffles 11 to reduce the interval between them, so as to ensure that only small-sized biomass fibers can pass through;

[0060] The guide cylinder 13 is installed at the bottom of the screening cylinder 9, and is used to guide the unqualified biomass fiber raw materials to fall back and be crushed again. The guide cylinder 13 helps to control the flow and direction of the biomass fiber raw materials. The servo motor 14 is installed on one side of the guide cylinder 13, and is responsible for driving the rotating circular baffle 15. The servo motor 14 ensures that the rotating circular baffle 15 can adjust the flow of biomass fibers in the guide cylinder 13 as needed, so as to achieve fine management of the biomass fiber raw materials.

[0061] A servo motor 3 16 is installed on the top of the screening drum 9, and the servo motor 3 16 is responsible for driving a rotating shaft 17. The rotating shaft 17 extends to the inside of the screening drum 9, and a rotating screen plate 18 is installed at the bottom thereof, which is used to achieve stirring and dispersion of the biomass fiber raw materials in the screening drum 9, thereby improving the screening efficiency. A discharge drum 19 is installed on one side of the screening drum 9, and the discharge drum 19 is located at the top of the biomass fiber raw material processing body 1. A hot air blower 20 is installed inside the discharge drum 19, which is used to further dry the screened biomass fiber raw materials before they are discharged, thereby helping to ensure that the screened biomass fibers reach the required degree of dryness before being discharged, thereby improving product quality;

[0062] The screening module allows for effective screening and preliminary drying of biomass fiber raw materials while maintaining automation and precise control. Through the integrated hot air blower 6, controller, temperature sensor 7, humidity sensor 8, servo motor 10, servo motor 2 14, servo motor 3 16 and hot air blower 2 20, the screening module can improve screening efficiency, reduce clogging of biomass fiber raw materials, and ensure that the material meets the drying requirements before discharge through the hot air blower 20, making the entire screening and preliminary drying process smoother and more efficient, and reducing dependence on manual operation.

[0063] See also Figure 2 An embodiment of the present invention is: a biomass fiber fabric with good toughness and a preparation device, wherein a filter core is installed inside the ventilation duct 5, and the filter core is used to prevent external impurities and broken biomass fibers inside the drying chamber 4 from clogging the ventilation duct 5.

[0064] Furthermore, the main function of the filter element is to prevent external impurities and biomass fibers from inside the crushing and drying chamber 4 from clogging the ventilation duct 5. During the processing of the biomass fiber raw materials, some fine fiber particles may be generated. If these fiber particles directly enter the ventilation duct 5 without being filtered, they will gradually accumulate and clog the ventilation duct 5, affecting the ventilation effect. By installing the filter element, these impurities and fibers can be effectively blocked from entering the ventilation duct 5, which can not only improve the ventilation effect and ensure the normal progress of the biomass fiber raw material processing process, but also extend the service life of the ventilation duct 5 and reduce the frequency of maintenance and cleaning.

[0066] Furthermore, a servo motor 4 21 is installed on the bottom wall of the biomass fiber raw material processing body 1 to provide the required power for the secondary crushing operation. The vertical reducer 22 converts the high speed of the servo motor 4 21 into a lower but higher torque output to meet the needs of the crushing operation. The rotating shaft 23 passes through the partition plate 3 and rotates under the drive of the vertical reducer 22, thereby driving the crushing knife 2 24 installed on its outside to perform the crushing operation. The crushing knife 2 24 rotates with the rotation of the rotating shaft 23 to cut and crush the biomass fiber raw material. The evenly arranged design can ensure the uniformity and consistency of the crushing effect.

The support plate 26 is located on one side of the biomass fiber raw material processing body 1, and plays a role in supporting and fixing the primary crushing module. The support plate 26 can also withstand the weight of the primary crushing module and the vibration during operation. The primary crushing module is used to perform preliminary crushing treatment on the biomass fiber raw material, and crush the biomass fiber raw material into smaller particles through mechanical action for subsequent processing or processing.

[0070] Furthermore, the main body of the primary crushing module is a crushing box 27, which is installed on the top of the support plate 26. The crushing box 27 is used to accommodate the biomass fiber raw material and perform crushing operations to prevent dust or fragments generated during the crushing process from scattering. Two groups of evenly arranged servo motors 5 28 are installed inside the crushing box 27. The output end of each servo motor 5 28 is installed with a rotating shaft 3 29. The rotating shaft 3 29 is a key component of the crushing operation. It rotates with the rotation of the servo motor 5 28, driving the crushing knife 1 30 installed on its outer side to cut and crush the biomass fiber raw material. The evenly arranged crushing knife 1 30 can ensure that the biomass fiber raw material can be evenly crushed at all positions.

[0071] A discharge pipe 31 is installed at the bottom of the crushing box 27, and the discharge pipe runs through the biomass fiber raw material processing body 1. The discharge pipe 31 is used to guide the crushed biomass fiber raw material out of the crushing box 27 and into the crushing and drying chamber 4. A protective door is also installed on the top of the crushing box 27 through a hinge.
