Description

Technical Field

[0001] This utility model relates to the field of plant fiber treatment technology, and in particular to a plant fiber surface treatment layer structure. Background Technology

[0002] In the field of plant fiber processing, the quality of plant fiber surface treatment has a crucial impact on the performance of subsequent products. Traditional plant fiber surface treatment processes often employ single steps of cleaning, drying, or humidification, which are not only inefficient but also difficult to precisely control the moisture content and surface cleanliness of the plant fibers. For example, during the cleaning process, conventional methods are insufficient to effectively remove fine impurities adhering to the plant fiber surface; the drying process cannot flexibly adjust the degree of drying according to different fiber characteristics; and the humidification process lacks effective recycling of excess moisture. These problems result in poor plant fiber treatment effects, significant resource waste, and an inability to meet the demands of modern production for high-quality and efficient plant fiber processing.

[0003] Therefore, we propose a plant fiber surface treatment layer structure. Utility Model Content

[0004] The main objective of this invention is to provide a plant fiber surface treatment layer structure to prevent problems such as low processing efficiency, difficulty in accurately controlling the moisture content and surface cleanliness of plant fibers in traditional plant fiber surface treatment processes, including the inability to effectively remove fine impurities, the inability to flexibly adjust the degree of drying according to fiber characteristics, and the lack of effective recycling of excess moisture. This invention aims to improve the surface treatment effect of plant fibers, reduce resource waste, and meet the demands of modern production for high-quality and efficient processing of plant fibers, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A plant fiber surface treatment layer structure includes a pretreatment box, with an inlet and an outlet at both ends of the pretreatment box. Inside the pretreatment box, from the inlet to the outlet, there are a cleaning chamber, a drying chamber, and a humidifying chamber. Smart sensors are installed adjacent to the cleaning chamber, drying chamber, and humidifying chamber. A cleaning device, a drying device, and a humidifying device are respectively installed above the interior of the cleaning chamber, drying chamber, and humidifying chamber. An air compressor, a fan, and a water tank are fixedly installed at the top of the pretreatment box and near the cleaning chamber, drying chamber, and humidifying chamber, respectively.

[0007] Both ends of the pretreatment box are fixedly connected to support plates. Conveyor belts are installed on the support plates and pass through the feed inlet, cleaning chamber, drying chamber, humidifying chamber and discharge outlet. Baffles are fixedly connected to the top of the support plates and at both ends of the conveyor belts.

[0008] The cleaning chamber and humidification chamber are respectively equipped with a debris collection box and a water collection box at the bottom. A filter screen is fixedly installed on the upper part of the inner wall of the water collection box. A water pump is fixedly installed on one side of the outer wall of the pretreatment box. The suction end of the water pump is fixedly connected to a first water pipe. The end of the first water pipe away from the water pump passes through the pretreatment box and is connected to the inside of the water collection box. A second water pipe is fixedly installed on the discharge end of the water pump. One end of the second water pipe is connected to the inside of the water storage tank.

[0009] By adopting the above technical solution, plant fibers are driven by the conveyor belt and enter the pretreatment box from the feed inlet. After being supported by the support plate and protected by the baffle, they pass through each treatment chamber in sequence. After entering the cleaning chamber, the cleaning roller first cleans the impurities on the surface of the plant fibers. The cleaned impurities fall into the collection box below the cleaning chamber for collection. Then, the air compressor provides power to the cleaning device, and the air blower blows the plant fibers to remove the residual dust and other impurities, further ensuring the cleanliness of the plant fibers.

[0010] After cleaning, the plant fibers are tested for moisture content by a smart sensor between the cleaning chamber and the drying chamber. If the detected moisture content is higher than the set value, it means that the plant fibers have too much moisture. At this time, the fan provides power to the drying device, and the plant fibers enter the drying chamber for hot air drying to remove excess moisture. If the moisture content meets the standard, they directly enter the humidification chamber for the next step of processing.

[0011] After the plant fibers have been dried, the intelligent sensor between the drying chamber and the humidification chamber will detect their moisture content again. When the detection result shows that the moisture content meets the requirements, the water tank provides water to the humidification device. The plant fibers enter the humidification chamber, and the humidification device humidifies them to restore the humidity of the plant fibers to a suitable range to meet the requirements of subsequent processing. During the humidification process, excess water will drip into the water collection tank below the humidification chamber. The filter screen on the upper part of the inner wall of the water collection tank filters impurities in the water.

[0012] The water pump draws the filtered water from the collection tank through the first water pipe, and then sends the water back to the storage tank through the second water pipe, realizing the recycling of water, improving the water resource utilization rate, and reducing water resource consumption in the pretreatment process.

[0013] After being cleaned, dried, and humidified, the plant fibers are discharged from the outlet, completing the entire pretreatment process and providing qualified raw materials for subsequent processing and production.

[0014] Furthermore, the cleaning device includes a sweeping mechanism and a blowing mechanism. The sweeping mechanism includes two sets of cylinders connected to the inner wall of the top of the cleaning chamber. A telescopic rod is fixedly connected to the telescopic end of the cylinder. A bracket is fixedly connected to the bottom end of the telescopic rod. A spring is sleeved on the outside of the telescopic rod and fixedly connected between the cylinder and the bracket. A cleaning roller is rotatably connected to the inner side of the bracket. A motor is fixedly installed on the outer wall of one end of the bracket. The output shaft of the motor is coaxially connected to one end of the cleaning roller.

[0015] By adopting the above technical solution, the cylinder serves as the main driving component for the up and down position of the cleaning roller. When it is necessary to adjust the distance between the cleaning roller and the plant fiber, the telescopic end of the cylinder will drive the telescopic rod to move up and down. The spring sleeved on the outside of the telescopic rod plays a role in buffering and auxiliary support. The spring is fixedly connected between the cylinder and the bracket. When the cleaning roller is subjected to the reaction force of the plant fiber or vibrates during the operation of the equipment, the spring can absorb some energy, so that the cleaning roller can better adapt to the thickness changes of the plant fiber and ensure that there is a suitable contact pressure between the cleaning roller and the plant fiber.

[0016] The motor is mounted on the outer wall of one end of the bracket, and the output shaft of the motor is coaxially connected to one end of the cleaning roller. When the motor starts, it drives the cleaning roller to rotate inside the bracket. The rotating cleaning roller comes into contact with the plant fibers on the conveyor belt, and the brushes on the surface of the cleaning roller clean the surface of the plant fibers, removing dust, impurities and other pollutants, thus achieving preliminary cleaning of the plant fibers. During the cleaning process, the rotation direction of the cleaning roller and the conveying direction of the conveyor belt can be designed according to the actual cleaning effect. For example, using reverse rotation can increase the cleaning force.

[0017] Furthermore, the blowing mechanism includes an air outlet pipe connected to an air compressor, the bottom end of which is connected to an air guide pipe, and a plurality of blowing heads are arranged at equal intervals at the bottom end of the air guide pipe.

[0018] By adopting the above technical solution, the air compressor is the power source of the entire blowing mechanism. The air compressor compresses the outside air to give it a certain pressure and flow rate, and then delivers the compressed air through the air outlet pipe. The air outlet pipe connects the air compressor and the air guide pipe, guiding the compressed air to the air guide pipe. The air guide pipe receives the compressed air from the air outlet pipe and distributes it evenly to multiple air blowers arranged at equal intervals. The design of multiple air blowers is to comprehensively blow away the plant fibers on the conveyor belt. When the compressed air is blown out from the air blower, a high-speed airflow is generated. This airflow directly acts on the surface of the plant fibers, blowing away the lighter dust, impurities, etc., that remain on the surface of the plant fibers after cleaning by the sweeping mechanism, or some small debris mixed between the fibers. The arrangement and angle of the air blowers can be optimized according to the conveying direction and distribution of the plant fibers to achieve the best blowing effect. For example, setting the angle of the air blower to be slightly inclined to the conveying direction of the plant fibers can make the impurities blow away along the conveying direction, making it easier to collect them.

[0019] Furthermore, the drying device includes an air supply pipe connected to a fan, the bottom end of the air supply pipe being connected to a heating box, and the bottom end of the heating box being connected to an air outlet hood.

[0020] By adopting the above technical solution, a fan acts as a power source, drawing in outside air and transporting it through an air supply duct. The duct guides the airflow generated by the fan to the heating chamber, providing a continuous airflow for the subsequent drying process. The heating chamber is a key component in the drying process. When air flows through the heating chamber, heating elements inside, such as heating wires, heat the air. The heating principle is based on the conversion of electrical energy into heat energy, raising the air temperature through heat conduction and convection. The temperature of the air inside the heating chamber can be controlled by adjusting the power of the heating elements, according to the temperature required for drying plant fibers. Generally, the air is heated to a certain temperature. The temperature range that can effectively evaporate moisture from plant fibers is usually determined based on factors such as the type and moisture content of the plant fibers. After being heated, hot air is evenly blown onto the plant fibers on the conveyor belt through the air outlet at the bottom of the heating chamber. The hot air comes into full contact with the surface of the plant fibers, and the heat of the hot air causes the moisture in the plant fibers to evaporate. After the moisture evaporates into water vapor, it is carried away by the flowing hot air, thereby reducing the moisture content of the plant fibers and achieving the purpose of drying. The design of the air outlet is usually to ensure that the hot air can evenly cover the plant fibers, ensuring that all parts of the plant fibers are effectively dried.

[0021] Furthermore, the humidification device includes a water outlet pipe connected to a water storage tank, and a water distribution pipe is connected to the bottom end of the water outlet pipe. Multiple sets of spray heads are arranged at equal intervals at the bottom end of the water distribution pipe.

[0022] By adopting the above technical solution, the water storage tank serves as a storage container for humidification water, providing a water source for the entire humidification process. Water flows out from the water storage tank through the water outlet pipe, which guides the direction of water flow and delivers the water to the water distribution pipe. The water distribution pipe disperses the water from the water outlet pipe to multiple sets of spray heads arranged at equal intervals. This design enables the water to be evenly distributed to each spray head, ensuring the uniformity of humidification.

[0023] The spray head is a key component of humidification. When water reaches the spray head, it sprays the water out in the form of a mist. The principle of spraying is usually to use special structures inside the spray head, such as small holes and nozzles, to break the water into small droplets under a certain pressure, thus creating a spray effect. The mist-like water droplets are evenly sprayed onto the surface of the dried plant fibers on the conveyor belt. The plant fiber surface absorbs these small water droplets, thereby increasing its own humidity. By controlling factors such as the spray volume, spray angle, and spray time of the spray head, the degree of humidification of the plant fibers can be precisely adjusted to achieve the humidity range required by subsequent processing processes.

[0024] Furthermore, a water inlet pipe is provided at the top of the water storage tank, a water outlet pipe is provided at one end of the water collection tank, the other end of the water outlet pipe extends through the pretreatment tank to the outside, and a valve is provided on the water outlet pipe.

[0025] By adopting the above technical solution, the water inlet pipe is located at the top of the water storage tank and is mainly used to replenish the water source to the water storage tank. Water can be introduced into the water storage tank from the outside through external water supply equipment such as water pipes and water pumps. In this way, during the operation of the humidification device, there can be enough water for the humidification operation of plant fibers.

[0026] The water collection tank is used to collect excess water dripping from the surface of the plant fibers during the humidification process. The water outlet pipe at one end of the water collection tank extends through the pretreatment tank to the outside. When it is necessary to clean the water in the water collection tank, the valve on the water outlet pipe is opened, and the water is discharged through the water outlet pipe to the drainage system outside the pretreatment tank, such as a floor drain or drainage pipe, under the action of gravity. The valve plays a role in controlling the drainage and can be used for drainage operations as needed, such as when the water level in the water collection tank reaches a certain height or after a certain working cycle.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) This utility model provides a plant fiber surface treatment layer structure. By sequentially setting a cleaning chamber, a drying chamber and a humidifying chamber in the pretreatment box, and cooperating with the conveyor belt to make the plant fiber complete the cleaning, drying and humidification treatment in sequence, the plant fiber surface treatment is integrated and streamlined. The air compressor, fan and water tank provide power and resources for the cleaning device, drying device and humidifying device respectively. The intelligent sensor monitors the fiber moisture content in real time to ensure that the treatment process is accurate and efficient, which greatly improves the efficiency and quality of plant fiber surface treatment.

[0029] (2) The present invention provides a plant fiber surface treatment layer structure. After humidification treatment, excess water falls into the water collection tank. Through the circulation system composed of water pump and water pipe, the water in the water collection tank is pumped back to the storage tank for reuse, which effectively reduces water waste. At the same time, impurities are collected in the impurity collection box during the cleaning process to avoid secondary pollution from impurities. While improving environmental protection benefits, it also reduces production costs and conforms to the production concept of sustainable development. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0036] To prevent the problems of low processing efficiency, difficulty in accurately controlling the moisture content and surface cleanliness of plant fibers in traditional plant fiber surface treatment processes, including the inability to effectively remove fine impurities, the inability to flexibly adjust the drying degree according to fiber characteristics, and the lack of effective recycling of excess moisture, and to improve the surface treatment effect of plant fibers and reduce resource waste, so as to meet the demands of modern production for high-quality and efficient processing of plant fibers, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a plant fiber surface treatment layer structure includes a pretreatment box 1. The pretreatment box 1 has an inlet 2 and an outlet 3 at both ends. Inside the pretreatment box 1, from the inlet 2 to the outlet 3, there are a cleaning chamber 4, a drying chamber 5, and a humidifying chamber 6. Smart sensors 23 are installed at adjacent positions of the cleaning chamber 4, the drying chamber 5, and the humidifying chamber 6. A cleaning device, a drying device, and a humidifying device are respectively installed above the interior of the cleaning chamber 4, the drying chamber 5, and the humidifying chamber 6. An air compressor 20, a fan 21, and a water tank 22 are fixedly installed at the top of the pretreatment box 1 and at positions close to the cleaning chamber 4, the drying chamber 5, and the humidifying chamber 6, respectively.

[0037] The pretreatment box 1 has support plates 7 fixedly connected to both outer walls. A conveyor belt 8 is provided on the support plate 7, and the conveyor belt 8 passes through the feed inlet 2, cleaning chamber 4, drying chamber 5, humidifying chamber 6 and discharge outlet 3. Baffles 34 are fixedly connected to the top of the support plate 7 and at both ends of the conveyor belt 8.

[0038] The cleaning chamber 4 and the humidification chamber 6 are respectively provided with a debris collection box 33 and a water collection box 14 at the bottom of the interior. A filter screen 15 is fixedly installed on the upper part of the inner wall of the water collection box 14. A water pump 16 is fixedly installed on one side of the outer wall of the pretreatment box 1. The suction end of the water pump 16 is fixedly connected to a first water pipe 17. The end of the first water pipe 17 away from the water pump 16 passes through the pretreatment box 1 and is connected to the interior of the water collection box 14. A second water pipe 18 is fixedly installed on the discharge end of the water pump 16. One end of the second water pipe 18 is connected to the interior of the water storage tank 22.

[0039] During use, the plant fibers are driven by the conveyor belt 8 and enter the pretreatment box 1 from the feed port 2. After being supported by the support plate 7 and protected by the baffle 34, they pass through each treatment chamber in sequence. After entering the cleaning chamber 4, the cleaning roller 12 first cleans the impurities on the surface of the plant fibers. The cleaned impurities fall into the collection box 33 below the cleaning chamber 4 for collection. Then, the air compressor 20 provides power to the cleaning device, and the air blower 26 blows the plant fibers to remove residual dust and other impurities, further ensuring the cleanliness of the plant fibers.

[0040] After cleaning, the plant fiber is tested for moisture content by the smart sensor 23 between the cleaning chamber 4 and the drying chamber 5. If the detected moisture content is higher than the set value, it means that the plant fiber has too much moisture. At this time, the fan 21 provides power to the drying device, and the plant fiber enters the drying chamber 5 for hot air drying to remove excess moisture. If the moisture content meets the standard, it directly enters the humidification chamber 6 for the next step of processing.

[0041] After the plant fiber has been dried, the intelligent sensor 23 between the drying chamber 5 and the humidification chamber 6 will detect its moisture content again. When the detection result shows that the moisture content meets the requirements, the water storage tank 22 provides water to the humidification device. The plant fiber enters the humidification chamber 6, and the humidification device humidifies it to restore the humidity of the plant fiber to a suitable range to meet the requirements of subsequent processing. During the humidification process, excess water will drip into the water collection tank 14 below the humidification chamber 6. The filter screen 15 on the upper part of the inner wall of the water collection tank 14 filters impurities in the water.

[0042] The water pump 16 draws the filtered water out of the water collection tank 14 through the first water pipe 17, and then sends the water back to the water storage tank 22 through the second water pipe 18, so as to realize the recycling of water, improve the water resource utilization rate, and reduce the water resource consumption in the pretreatment process.

[0043] After being cleaned, dried, and humidified, the plant fibers are discharged from outlet 3, completing the entire pretreatment process and providing qualified raw materials for subsequent processing and production.

[0044]

[0045] For example, such as Figure 4 As shown, this utility model also includes a cleaning device comprising a sweeping mechanism and a blowing mechanism. The sweeping mechanism includes two sets of cylinders 19 connected to the inner wall of the top of the cleaning chamber 4. A telescopic rod 9 is fixedly connected to the telescopic end of the cylinder 19. A bracket 10 is fixedly connected to the bottom end of the telescopic rod 9. A spring 11 is sleeved on the outside of the telescopic rod 9 and is fixedly connected between the cylinder 19 and the bracket 10. A cleaning roller 12 is rotatably connected to the inner side of the bracket 10. A motor 13 is fixedly installed on the outer wall of one end of the bracket 10. The output shaft of the motor 13 is coaxially connected to one end of the cleaning roller 12.

[0046] In use, the cylinder 19 serves as the main driving component for the up and down position of the cleaning roller 12. When it is necessary to adjust the distance between the cleaning roller 12 and the plant fiber, the telescopic end of the cylinder 19 will drive the telescopic rod 9 to move up and down. The spring 11 sleeved on the outside of the telescopic rod 9 plays a role in buffering and auxiliary support. The spring 11 is fixedly connected between the cylinder 19 and the bracket 10. When the cleaning roller 12 is subjected to the reaction force of the plant fiber or vibrates during the operation of the equipment, the spring 11 can absorb some energy, so that the cleaning roller 12 can better adapt to the thickness changes of the plant fiber and ensure that there is a suitable contact pressure between the cleaning roller 12 and the plant fiber.

[0047] The motor 13 is installed on the outer wall of one end of the bracket 10. The output shaft of the motor 13 is coaxially connected to one end of the cleaning roller 12. When the motor 13 starts, it drives the cleaning roller 12 to rotate inside the bracket 10. The rotating cleaning roller 12 comes into contact with the plant fibers on the conveyor belt. The brush bristles on the surface of the cleaning roller 12 clean the surface of the plant fibers, removing dust, impurities and other pollutants, thus achieving preliminary cleaning of the plant fibers. During the cleaning process, the rotation direction of the cleaning roller 12 and the conveying direction of the conveyor belt 8 can be designed according to the actual cleaning effect. For example, reverse rotation can increase the cleaning force.

[0048] For example, such as Figure 2 As shown, the present invention also includes a blower mechanism comprising an air outlet pipe 24 connected to an air compressor 20, the bottom end of the air outlet pipe 24 being connected to an air guide pipe 25, and a plurality of blower heads 26 being arranged at equal intervals at the bottom end of the air guide pipe 25.

[0049] In operation, the air compressor 20 is the power source for the entire blowing mechanism. The air compressor 20 compresses outside air to achieve a certain pressure and flow rate, then delivers the compressed air through the outlet pipe 24. The outlet pipe 24 connects the air compressor 20 and the air guide pipe 25, guiding the compressed air to the air guide pipe 25. The air guide pipe 25 receives the compressed air from the outlet pipe 24 and evenly distributes it to multiple equally spaced blowing heads 26. The multiple blowing heads 26 are designed to thoroughly blow away the plant fibers on the conveyor belt. When compressed air is blown out from the air head 26, a high-speed airflow is generated. This airflow acts directly on the surface of the plant fiber. The airflow can blow away the lighter dust, impurities, etc., that remain on the surface of the plant fiber after cleaning by the sweeping mechanism, or some small debris mixed between the fibers. The arrangement and angle of the air head 26 can be optimized according to the conveying direction and distribution of the plant fiber to achieve the best blowing effect. For example, the angle of the air head 26 can be set to be slightly inclined to the conveying direction of the plant fiber, so that the impurities can be blown away along the conveying direction and are easy to collect.

[0050] For example, such as Figure 2 As shown, the present invention also includes a drying device comprising an air supply pipe 27 connected to a fan 21, the bottom end of the air supply pipe 27 being connected to a heating box 28, and the bottom end of the heating box 28 being connected to an air outlet hood 29.

[0051] In operation, the fan 21 acts as a power source, drawing in outside air and delivering it through the air supply duct 27. The air supply duct 27 guides the airflow generated by the fan 21 to the heating chamber 28, providing a continuous airflow for the subsequent drying process. The heating chamber 28 is a key component in the drying process. When air flows through the heating chamber 28, heating elements inside, such as heating wires, heat the air. The heating principle is based on the conversion of electrical energy into heat energy, raising the air temperature through heat conduction and convection. The temperature of the air inside the heating chamber 28 can be controlled by adjusting the power of the heating elements according to the temperature required for drying the plant fibers. Generally, the air... The heating process involves heating the plant fibers to a temperature range that effectively evaporates moisture. This temperature range is typically determined based on factors such as the type and moisture content of the plant fibers. After heating, the hot air is evenly blown onto the plant fibers on the conveyor belt 8 through the air outlet hood 29 at the bottom of the heating chamber 28. The hot air makes full contact with the surface of the plant fibers, and the heat of the hot air causes the moisture in the plant fibers to evaporate. After the moisture evaporates into water vapor, it is carried away by the flowing hot air, thereby reducing the moisture content of the plant fibers and achieving the purpose of drying. The air outlet hood 29 is designed to ensure that the hot air can evenly cover the plant fibers, ensuring that all parts of the plant fibers are effectively dried.

[0052] For example, such as Figure 2 As shown, the present invention also includes a humidification device comprising a water outlet pipe 30 connected to a water storage tank 22, the bottom end of the water outlet pipe 30 being connected to a water distribution pipe 31, and a plurality of spray nozzles 32 being arranged at equal intervals at the bottom end of the water distribution pipe 31.

[0053] When in use, the water storage tank 22 serves as a storage container for humidification water, providing a water source for the entire humidification process. Water flows out from the water storage tank 22 through the water outlet pipe 30, which guides the direction of water flow and delivers the water to the water distribution pipe 31. The function of the water distribution pipe 31 is to disperse the water from the water outlet pipe 30 to multiple sets of spray heads 32 arranged at equal intervals. This design enables the water to be evenly distributed to each spray head 32, ensuring the uniformity of humidification.

[0054] The spray head 32 is a key component for humidification. When water reaches the spray head 32, it sprays the water out in the form of a mist. The principle of spraying is usually to use special structures inside the spray head, such as small holes and nozzles, to break the water into small droplets under a certain pressure, thus creating a spray effect. The mist-like water droplets are evenly sprayed onto the surface of the dried plant fibers on the conveyor belt 8. The plant fiber surface absorbs these small water droplets, thereby increasing its own humidity. By controlling factors such as the spray volume, spray angle, and spray time of the spray head 32, the humidification degree of the plant fibers can be precisely adjusted to achieve the humidity range required by subsequent processing.

[0055] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes a water inlet pipe 35 provided at the top of the water storage tank 22, a water outlet pipe 36 provided at one end of the water collection tank 14, the other end of the water outlet pipe 36 extending through the pretreatment tank 1 to the outside, and a valve provided on the water outlet pipe 36.

[0056] When in use, the water inlet pipe 35 is located at the top of the water storage tank 22 and is mainly used to replenish the water storage tank 22. Water can be introduced into the water storage tank 22 from the outside through external water supply equipment such as water pipes and water pumps. In this way, during the operation of the humidification device, there can be enough water for the humidification operation of plant fibers.

[0057] The water collection tank 14 is used to collect excess water dripping from the surface of the plant fibers during the humidification process. The water outlet pipe 36 at one end of the water collection tank 14 extends through the pretreatment tank 1 to the outside. When it is necessary to clean the water in the water collection tank 14, the valve on the water outlet pipe 36 is opened. Under the action of gravity, the water is discharged through the water outlet pipe 36 to the drainage system outside the pretreatment tank 1, such as a floor drain or drainage pipe. The valve plays the role of controlling drainage and can be used for drainage operation according to actual needs, such as when the water level in the water collection tank 14 reaches a certain height or after a certain working cycle.

[0058] It should be noted that this utility model is a plant fiber surface treatment layer structure, which replenishes water to the water storage tank 22 through the water supply pipe 35 to ensure that the humidification device has enough water for subsequent operation;

[0059] Plant fibers are placed on conveyor belt 8 and enter pretreatment box 1 from feed port 2 via conveyor belt 8. Conveyor belt 8 is supported by support plate 7 and baffles 34 at both ends prevent plant fibers from falling.

[0060] The air compressor 20 provides power to the cleaning device. The sweeping mechanism in the cleaning device works first. The cylinder 19 adjusts the distance between the cleaning roller 12 and the plant fiber as needed. The motor 13 drives the cleaning roller 12 to rotate. The brushes sweep away dust, impurities and other debris from the surface of the plant fiber. Then the blowing mechanism works. The air compressor 20 delivers compressed air to multiple blowing heads 26 through the air outlet pipe 24 and the air guide pipe 25. The high-speed airflow blows away the lighter dust and impurities remaining on the surface of the plant fiber. The impurities generated during the cleaning process fall into the collection box 33 below the cleaning chamber 4 for collection.

[0061] The intelligent sensor 23 detects parameters such as the moisture content of the plant fiber. If drying is required, the fan 21 acts as a power source to draw in outside air and deliver it to the heating box 28 through the air supply pipe 27. The heating element inside the heating box 28 heats the air. The heated air is then blown evenly onto the plant fiber on the conveyor belt 8 through the air outlet hood 29, causing the moisture in the plant fiber to evaporate and reducing its moisture content.

[0062] The intelligent sensor 23 detects parameters such as the moisture content of the plant fibers. If humidification is required, water in the storage tank 22 is delivered to multiple spray nozzles 32 through the outlet pipe 30 and the distribution pipe 31. The spray nozzles 32 spray water in a mist form, evenly spraying it onto the surface of the dried plant fibers to increase their humidity. Excess water drips into the water collection tank 14 below the humidification chamber 6. The filter screen 15 on the upper part of the inner wall of the water collection tank 14 filters out impurities in the water. The water pump 16 draws water from the water collection tank 14 through the first water pipe 17 and sends it back to the storage tank 22 through the second water pipe 18, realizing water recycling. (The intelligent sensor 23 continuously monitors the moisture content data of the plant fibers and compares it with the pre-set data.) The sensor compares the measured value with the standard moisture content range. When the measured value is lower than the lower limit of the standard, the sensor immediately sends a drying demand signal to the control system. After receiving the signal, the control system triggers the fan 21 and the heating box 28 to start working. Outside air is drawn in by the fan, heated by the heating element in the heating box, and then blown evenly onto the plant fibers through the air outlet hood to promote moisture evaporation and reduce the moisture content. When the measured value is higher than the upper limit of the standard, the sensor sends a humidification demand signal. The control system controls the water outlet pipe 30 and the water distribution pipe 31 of the water storage tank 22 to open. The spray head 32 atomizes the water and sprays it onto the surface of the plant fibers to increase humidity. At the same time, excess water falls into the water collection tank 14 and is circulated back to the water storage tank 22 through the water pump 16 and water pipes.

[0063] In terms of hardware, the control system is based on a microcontroller (PLC, single-chip microcomputer, etc.) and is equipped with data acquisition, signal processing and drive modules. The data acquisition module converts the analog signal of the intelligent sensor 23 into a digital signal and transmits it to the microcontroller. After processing and judgment, the drive module controls the operation of the actuator.

[0064] The software design adopts modular programming, including sensor data acquisition, data processing and judgment, and actuator control program. The program presets various threshold parameters and sets the priority and working sequence of the actuator. Through human-computer interaction interfaces such as touch screen and host computer, it realizes parameter modification, equipment status monitoring and fault alarm, which facilitates operation and management.

[0065] After being cleaned, dried, and humidified, the plant fibers are conveyed out from the discharge port 3 by the conveyor belt 8, completing the pretreatment process.

[0066] When the water level in the water collection tank 14 reaches a certain height or after a certain working cycle, the valve on the water outlet pipe 36 is opened to discharge the water in the water collection tank 14 to the drainage system outside the pretreatment tank 1.
