Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric processing technology, and more specifically, to a raw material conveying device and method for nonwoven fabric processing. Background Technology

[0002] Nonwoven fabrics are made from chemical fibers and various plant fibers, using water or air as a suspension medium on wet or dry papermaking machines. Although they are cloths, they are not woven, hence the name nonwoven fabric. Common agricultural nonwoven fabrics include crop protection cloths, seedling raising cloths, irrigation cloths, and thermal insulation curtains. They also have wide applications in the hygiene products field, such as sanitary napkins and diapers, utilizing the environmentally friendly and skin-friendly properties of natural fibers. In the processing of agricultural nonwoven fabrics, the transportation of natural plant fiber raw materials is one of the key links. Its efficiency and stability directly affect the operating quality of the entire production line and the performance of the products. Traditional nonwoven fabric raw material transportation methods mostly use manual handling or simple mechanical conveying equipment. Currently, common transportation methods mainly include two categories: mechanical transportation and pneumatic transportation. In mechanical transportation, screw conveyors (auger conveyors) and belt conveyors are widely used for transporting granular or short fiber raw materials, with advantages such as simple structure, convenient operation, and low maintenance costs. These transportation equipment are used to varying degrees in current nonwoven fabric production lines and can meet the transportation needs of conventional raw materials.

[0003] Chinese Patent Publication No. CN119929552A discloses a raw material conveying device for non-woven fabric processing. It mainly includes a conveying pipe with a discharge pipe fixedly installed through the outer wall of one end and a feed pipe fixedly installed through the outer wall of the other end. It also includes a dispersing mechanism located above the feed pipe, comprising a feed frame fixedly installed on the top surface of the feed pipe and a screening mechanism located inside the feed frame. When a motor is turned on, it drives a rotating shaft, a rotating bar, and a fixed column to rotate. The fixed column drives a block to move within a trough, causing a moving frame and an adjusting plate to reciprocate. The inclined trough drives a cylinder and a moving bar to reciprocate. The moving bar drives two dispersing rods (dispersing rod one and dispersing rod two) below to reciprocate. The dispersing rods disperse polypropylene particles, preventing them from bridging and clogging in the feed frame, ensuring the polypropylene particles fall normally and evenly, and improving conveying efficiency.

[0004] In practical applications, existing technologies often encounter problems. Nonwoven fabrics are made from long fibers or irregularly shaped natural plant fibers, which are prone to entanglement, jamming between the spiral blades and the pipe wall, or localized accumulation during transport, leading to blockages that severely affect conveying efficiency and system stability. Furthermore, the fibers are prone to static electricity during transport, further exacerbating the mutual adsorption and entanglement between fibers. This not only affects the smooth flow of materials but may also interfere with the normal operation of production equipment. Therefore, to address these technical problems, it is necessary to provide a raw material conveying device and method for nonwoven fabric processing. Summary of the Invention

[0005] The purpose of this invention is to provide a raw material conveying device and method for nonwoven fabric processing, so as to solve the above-mentioned problems.

[0006] To achieve the above objectives, an embodiment of the present invention provides the following technical solution: A raw material conveying device and method for nonwoven fabric processing includes a shell, a pre-dispersing component, a conveying anti-blocking component, and a dispersing component. An air inlet pipe is connected to the outer surface of the shell. The pre-dispersing component includes a feed pipe fixedly connected to the inner cavity of the shell. A dispersing frame is fixedly connected to and communicates with the upper end of the feed pipe. A rotating pipe is symmetrically rotatably connected to the inner cavity of the dispersing frame. Multiple dispersing pipes are uniformly fixedly connected to and communicate with the outer surface of the rotating pipe. A breathable membrane is fixedly connected to the opening of each dispersing pipe. A fixing ring is fixedly connected to the inner cavity of each dispersing pipe, and the inner cavity of the fixing ring abuts against... The ionization air ball includes a conveying anti-blocking component comprising a conveying cylinder fixedly connected to the inner cavity of the outer shell. The outer surface of the conveying cylinder is evenly provided with multiple oblique air holes. A waterproof and breathable membrane is fixedly connected to the inner cavity of the oblique air holes. A spiral conveying rod is rotatably connected to the inner cavity of the conveying cylinder. The agitation component includes multiple sleeves fixedly connected to the outer shell and the inner cavity of the conveying cylinder. An electromagnet is fixedly connected to the bottom of the inner cavity of each sleeve. A agitation rod is slidably connected to the inner cavity of each sleeve. A magnetic block is fixedly connected to the end of the agitation rod near the electromagnet. Multiple moisture holes are provided on the end of the agitation rod away from the magnetic block and on its outer surface.

[0007] As a further improvement of the present invention, a fixing ring is fixedly connected to the outer surfaces of both ends of the outer shell, and a mounting rod is fixedly connected to the outer surface of the fixing ring.

[0008] As a further improvement of the present invention, the lower end of the feed pipe is fixedly connected to and communicates with the outer surface of the conveying cylinder, a motor is fixedly connected to the outer surface of the dispersing frame, and the output shaft end of the motor passes through the dispersing frame and is fixedly connected to the rotating pipe.

[0009] As a further improvement of the present invention, the end of the rotating tube away from the motor passes through the disassembly frame and is fixedly connected with a gear on its outer surface. There are two gears that are meshed together, and one end of the rotating tube is connected to an air inlet pipe II through a rotating joint.

[0010] As a further improvement of the present invention, a drive motor is fixedly connected to the outer surface of the conveying cylinder, the output shaft of the drive motor passes through the conveying cylinder and is fixedly connected to the spiral conveying rod, and a cavity is provided between the outer shell and the conveying cylinder and is respectively connected to the air inlet pipe and the inclined air hole.

[0011] As a further improvement of the present invention, the inner cavity of the conveying cylinder is divided into multiple continuous conveying chambers by the spiral blades of the spiral conveying rod, and the inclined air hole is inclined upward with the spiral conveying rod as the reference line and the inclination angle is between 30-60°.

[0012] As a further improvement of the present invention, the electromagnet is magnetically connected to the magnetic block, and the moisture hole located on the outer surface of the stirring rod abuts against the inner wall of the sleeve.

[0013] As a further improvement of the present invention, one end of the stirring rod is connected to a moisture connection pipe, the outer surface of the moisture connection pipe is fixedly connected to the inner wall of the magnetic block, and the moisture connection pipe moves within the sleeve and the inner cavity of the electromagnet.

[0014] As a further improvement of the present invention, the other end of the moisture connection pipe is located outside the sleeve and is connected to the moisture main pipe, the moisture main pipe is a flexible hose, the inner cavity of the moisture hole is fixedly connected to a waterproof and breathable membrane, and the stirring rod is made of elastic material.

[0015] A method for conveying raw materials for nonwoven fabric processing includes the following steps: S1: The two rotating tubes and the dispersing tube rotate inward simultaneously to mechanically disperse the clumps of nonwoven fabric fiber raw materials. When compressed air flows inside the dispersing tube, it is evenly sprayed out through the breathable membrane, forming a strong blowing effect on the fibers. The ion wind ball generates a large number of positive and negative ions that quickly attach to the fiber surface with the airflow, neutralizing the static charge accumulated due to friction and helping the fibers to loosen quickly.

[0016] S2: The drive motor drives the spiral conveyor to rotate and convey the pre-dispersed fibers. Compressed air enters the cavity between the outer shell and the conveyor cylinder and is sprayed along the conveying direction through the oblique air holes to prevent the fibers from getting stuck on the edge of the blades or accumulating at the bottom of the conveying cavity. An infrared detector is embedded inside the conveyor cylinder to detect changes in the transmittance of infrared light in real time to determine whether there is fiber accumulation in the area.

[0017] S3: When the electromagnet inside the sleeve is energized, the stirring rod moves outward and vibrates at high frequency under the action of the airflow injected by the inclined air hole, which helps to loosen and clear the fibers. The moisture holes opened on the outer surface of the stirring rod provide moisture as needed, reducing the risk of electrostatic adsorption, while softening the fiber surface, reducing entanglement, and making it easier to separate and redisperse.

[0018] Compared with the prior art, the advantages of this invention are: (1) This scheme uses a starting motor to drive two rotating tubes and a dispersing tube to rotate inward simultaneously, mechanically dispersing the clumps of nonwoven fabric fiber raw materials. For fiber materials that are often in a clump or entangled state, it effectively performs preliminary physical dispersal. Then, the ion wind ball is dynamically moved by air pressure, so that the ion wind directly acts on the fibers during the dispersal process, forming a strong blowing effect on the fibers. Moreover, these ions are quickly attached to the fiber surface with the airflow, neutralizing the static charge accumulated due to friction, and significantly reducing the electrostatic adsorption force between fibers. This process not only helps the fibers to loosen quickly, but also effectively prevents the static electricity between long fibers from causing agglomeration. The entanglement and clumping phenomena of the fibers are eliminated. The dual anti-entanglement mechanism of "mechanical separation + electrostatic elimination" reduces the entanglement rate of fiber conveying. (2) This scheme drives the screw conveyor to rotate by the drive motor, pushes the pre-dispersed fibers along the conveying cavity to the discharge pipe, introduces compressed air into the air inlet pipe, and sprays it along the conveying direction through the inclined air hole. The inclined air hole is at an angle of 30-60° with the screw conveying direction, forming an upward airflow. The airflow direction is consistent with the screw conveying direction, forming a "air flotation + mechanical" composite propulsion mechanism. The airflow forms a dynamic air film between the fiber and the blade, reducing frictional resistance and preventing the fiber from getting stuck on the blade. The edges or accumulation at the bottom of the conveying chamber can effectively prevent local blockage caused by entanglement and accumulation, and ensure continuous and stable operation; (3) This solution uses an infrared detector embedded inside the conveying cylinder to detect the change in the transmittance of infrared light in real time to determine whether there is fiber accumulation in the area. Once the transmittance of a certain area drops below the set threshold, the corresponding fault response mechanism is immediately activated, the electromagnet in the sleeve is activated, and the stirring rod is pushed outward by magnetic repulsion to enter the corresponding conveying chamber area for physical stirring. It forms high-frequency vibration with the airflow sprayed from the inclined air hole, and quickly clears the blockage. During normal operation, the moisture hole at the end of the stirring rod slowly The slow release of trace amounts of moisture forms a thin water film on the fiber surface, reducing its electrostatic potential and preventing the fibers from adsorbing and entangled due to static electricity. When blockage occurs, the agitator moves outward, exposing multiple moisture pores on the outer wall. A large amount of moisture is concentrated and sprayed onto the blockage area, locally increasing the fiber humidity, softening the fiber surface, reducing its rigidity and adhesion, making it easier to separate and redisperse. This "on-demand humidification" strategy not only improves the blockage treatment effect but also avoids other problems that may be caused by excessive humidification throughout the entire process (such as clumping, mold, etc.). It is energy-efficient and highly effective, greatly enhancing the device's adaptability to complex fiber materials and its anti-blockage performance. Attached Figure Description

[0021] The technical solution 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 A raw material conveying device and method for nonwoven fabric processing includes a shell 1, a pre-dispersing component 2, a conveying anti-blocking component 3, and a dispersing component 4. An air inlet pipe 103 is connected to the outer surface of the shell 1. The pre-dispersing component 2 includes a feed pipe 201 fixedly connected to the inner cavity of the shell 1. A dispersing frame 202 is fixedly connected to and connected to the upper end of the feed pipe 201. A rotating pipe 204 is symmetrically rotatably connected to the inner cavity of the dispersing frame 202. A plurality of dispersing pipes 207 are uniformly fixedly connected to and connected to the outer surface of the rotating pipe 204. A breathable membrane 208 is fixedly connected to the opening of the dispersing pipe 207. A fixing ring 209 is fixedly connected to the inner cavity of the dispersing pipe 207. An ion wind ball 210 abuts against the inner cavity of the fixing ring 209. A fixing ring 101 is fixedly connected to the outer surface of both ends of the outer shell 1. A mounting rod 102 is fixedly connected to the outer surface of the fixing ring 101. The lower end of the feed pipe 201 is fixedly connected to and communicates with the outer surface of the conveying cylinder 301. A motor 203 is fixedly connected to the outer surface of the dispersing frame 202. The output shaft end of the motor 203 passes through the dispersing frame 202 and is fixedly connected to the rotating pipe 204. The end of the rotating pipe 204 away from the motor 203 passes through the dispersing frame 202 and has a gear 206 fixedly connected to its outer surface. There are two gears 206 that are meshed together. One end of the rotating pipe 204 is connected to an air inlet pipe 205 through a rotating joint.

[0023] Nonwoven fabric fiber raw materials are put into the dispersing frame 202, and at the same time, the upper end of the air inlet pipe 205 is connected to the external air compression device to introduce compressed air.

[0024] Next, the motor 203 is started to drive a rotating tube 204 to rotate, and through the meshing of two gears 206, the two rotating tubes 204 and the dispersing tube 207 are driven to rotate inward simultaneously, mechanically dispersing the clumps of nonwoven fabric fiber raw materials. This dispersing action is uniform, efficient and covers the entire dispersing area, effectively performing preliminary physical dispersing of fiber materials that are often in a clump or entangled state.

[0025] The rotating pipe 204 is connected to the air inlet pipe 205 through a rotating joint with a sealing function, so that compressed air can flow steadily into the dispersing pipe 207. When the compressed air flows inside the dispersing pipe 207, the airflow pressure will drive the ion air ball 210 to move outward in a straight line with the cooperation of the sliding rod 212, and drive the spring 213 to extend. At this time, the ion air ball 210 leaves the fixed ring 209, and the airflow flows out from the gap between the ion air ball 210 and the fixed ring 209, and is evenly sprayed out through the breathable membrane 208. The breathable membrane 208 adopts a high-density microporous structure, which can not only ensure the smooth passage of airflow, but also effectively prevent fiber particles from entering the dispersing pipe and causing blockage, thereby playing a filtering and protection role and forming a strong blowing effect on the fibers.

[0026] The ion wind ball 210 generates a large number of positive and negative ions. These ions quickly attach to the fiber surface with the airflow, neutralizing the static charge accumulated by friction and significantly reducing the electrostatic adsorption force between fibers. This process not only helps the fibers to loosen quickly, but also effectively prevents the entanglement and clumping of long fibers due to static electricity, providing a good material foundation for subsequent conveying. Example

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 A raw material conveying device and method for nonwoven fabric processing includes a conveying anti-blocking component 3, which includes a conveying cylinder 301 fixedly connected to the inner cavity of the outer shell 1. The outer surface of the conveying cylinder 301 is evenly provided with a plurality of oblique air holes 304. A waterproof and breathable membrane 3041 is fixedly connected to the inner cavity of the oblique air holes 304. A spiral conveying rod 305 is rotatably connected to the inner cavity of the conveying cylinder 301.

[0028] A drive motor 303 is fixedly connected to the outer surface of the conveying cylinder 301. The output shaft of the drive motor 303 passes through the conveying cylinder 301 and is fixedly connected to the spiral conveying rod 305. A cavity is provided between the outer shell 1 and the conveying cylinder 301 and is connected to the air inlet pipe 103 and the inclined air hole 304 respectively. The inner cavity of the conveying cylinder 301 is divided into multiple continuous conveying cavities 306 by the spiral blades of the spiral conveying rod 305. The inclined air hole 304 is inclined upward with the spiral conveying rod 305 as the reference line and the inclination angle is between 30-60°.

[0029] The pre-treated and dispersed fiber raw material enters the conveying cylinder 301 through the feed pipe 201. At this time, the drive motor 303 drives the spiral conveying rod 305 to push the pre-dispersed fiber along the conveying chamber 306 to the discharge pipe 302 for discharge. The speed is controlled within a reasonable range to ensure that the fiber is pushed forward smoothly without being excessively squeezed.

[0030] The spiral conveyor 305 is divided into multiple continuous conveying chambers 306 by the spiral arrangement of the blades (each conveying chamber 306 represents a single conveying area, and multiple chambers are connected together to form a continuous conveying area; each conveying chamber 306 is responsible for pushing a section of fiber, and multiple conveying chambers 306 are connected in series to form an overall continuous conveying channel). At the same time, the upper end of the air inlet pipe 103 is also connected to an external air compression device to introduce compressed air. The compressed air enters the cavity between the outer shell 1 and the conveying cylinder 301 and is sprayed along the conveying direction through the inclined air hole 304. The inclined air hole 304 is set at an angle of 30-60° with the spiral conveyor 305 as the reference line, forming an upward airflow. This makes the airflow direction consistent with the spiral conveying direction, forming a "air flotation + mechanical" composite propulsion mechanism. The airflow forms a dynamic air film between the fiber and the blades, reducing frictional resistance and preventing the fiber from getting stuck at the edge of the blade or accumulating at the bottom of the conveying chamber, which significantly improves the anti-clogging capability of the system.

[0031] The waterproof and breathable membrane 3041 can prevent fibers and water vapor from flowing back into the air path and ensure stable airflow. An infrared detector is embedded inside the conveying cylinder 301 (installed in each independent conveying chamber 306 area). Each infrared detector corresponds to one conveying chamber 306. By detecting the change in infrared light transmittance in real time, it can be determined whether there is fiber accumulation in the area. Once the transmittance of a certain area drops below the set threshold, it indicates that the area may be blocked or locally accumulated, and the corresponding fault response mechanism is immediately activated. Example

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 9 A raw material conveying device and method for nonwoven fabric processing includes a stirring assembly 4, comprising multiple sleeves 401 fixedly connected to the inner cavity of the outer shell 1 and the conveying cylinder 301. An electromagnet 402 is fixedly connected to the bottom of the inner cavity of the sleeve 401, and a stirring rod 403 is slidably connected to the inner cavity of the sleeve 401. A magnetic block 404 is fixedly connected to the end of the stirring rod 403 near the electromagnet 402. Multiple moisture holes 4031 are provided on the end of the stirring rod 403 away from the magnetic block 404 and on its outer surface.

[0033] Electromagnet 402 and magnetic block 404 are magnetically connected. Moisture vent 4031 on the outer surface of stirring rod 403 abuts against the inner wall of sleeve 401. One end of stirring rod 403 is connected to moisture connection pipe 405. The outer surface of moisture connection pipe 405 is fixedly connected to the inner wall of magnetic block 404. Moisture connection pipe 405 moves within the inner cavity of sleeve 401 and electromagnet 402. The other end of moisture connection pipe 405 is located outside sleeve 401 and is connected to moisture main pipe 406. Moisture main pipe 406 is a flexible hose. Waterproof and breathable membrane 3041 is fixedly connected to the inner cavity of moisture vent 4031. Stirring rod 403 is made of elastic material.

[0034] When the electromagnet 402 inside the sleeve 401 is energized, it generates magnetic repulsion with the magnetic block 404 at one end of the stirring rod 403, causing the stirring rod 403 to move outward and enter the conveying chamber 306 area. Under the action of the airflow ejected by the inclined air hole 304, it vibrates at high frequency, further assisting in the loosening and unblocking of the fibers, and preventing them from re-aggregating or getting stuck in the conveying path.

[0035] The moisture main pipe 406 supplies moisture to the agitator 403 through the moisture connecting pipe 405. Under normal circumstances, the moisture is discharged through a moisture hole 4031 opened at one end of the agitator 403. The moisture hole 4031 opened on the outer surface of the agitator 403 is blocked by the sleeve 401, forming a thin water film on the surface of the normally conveyed fiber, reducing electrostatic adsorption. When blockage occurs, the agitator 403 moves outward. At this time, the moisture hole 4031 opened on the outer surface of the agitator 403 is unblocked. Multiple moisture holes 4031 simultaneously deliver moisture to the blocked area, increasing the fiber humidity in the blocked area, reducing the risk of electrostatic adsorption, softening the fiber surface, reducing entanglement, and making it easier to separate and redisperse.

[0036] The stirring rod 403 extends into the spiral blade when it rotates to a specific angle, and then retracts in time before the next blade arrives. The speed at which the stirring rod 403 extends and retracts must be much faster than the rotation speed of the spiral blade to ensure that the operation is completed within the safety window. For example, if the spiral shaft rotates at 60 RPM, which is 1 revolution per second, then each 30° angle takes only about 55 milliseconds. The action response time must be below this. A sensor is embedded inside the stirring rod 403 to detect whether the stirring rod 403 returns to its position on time. If it does not retract in time, the machine should stop immediately and an alarm should be triggered to prevent collision.

[0037] Working principle: During operation, the nonwoven fabric fiber material is fed into the dispersing frame 202. Simultaneously, the upper end of the second air inlet pipe 205 is connected to an external air compressor to introduce compressed air. Then, the motor 203 is started, driving a rotating pipe 204 to rotate. Through the meshing of two gears 206, both rotating pipes 204 and the dispersing pipe 207 rotate inwards simultaneously, mechanically dispersing the clumps of nonwoven fabric fiber material. The rotating pipe 204 remains connected to the second air inlet pipe 205 via a rotating joint with a sealing function, ensuring a stable flow of compressed air into the dispersing pipe 207. Inside, when compressed air flows inside the dispersing tube 207, the airflow pressure drives the ion air ball 210 to move outward in a straight line with the cooperation of the sliding rod 212, and drives the spring 213 to extend. At this time, the ion air ball 210 leaves the fixing ring 209, and the airflow flows out from the gap between the ion air ball 210 and the fixing ring 209, and is evenly sprayed out through the breathable membrane 208, forming a strong blowing effect on the fibers. The ion air ball 210 generates a large number of positive and negative ions. These ions quickly attach to the fiber surface with the airflow, neutralizing the static charge accumulated by friction and helping the fibers to loosen quickly.

[0038] The pre-treated and dispersed fiber raw material enters the conveying cylinder 301 through the feed pipe 201. At this time, the drive motor 303 drives the spiral conveyor 305 to rotate, pushing the pre-dispersed fiber along the conveying cavity 306 to the discharge pipe 302 for discharge. Simultaneously, the upper end of the air inlet pipe 103 is also connected to an external air compression device to introduce compressed air. The compressed air enters the cavity between the outer shell 1 and the conveying cylinder 301 and is sprayed along the conveying direction through the inclined air hole 304 to prevent the fiber from getting stuck on the blade edge or accumulating at the bottom of the conveying cavity. An infrared detector is embedded inside the conveying cylinder 301 to determine whether there is fiber accumulation in the area by detecting changes in the transmittance of infrared light in real time, and to activate the corresponding fault response mechanism. At this time, the electromagnet 402 in the inner cavity of the sleeve 401 is energized and interacts with the agitator. The magnetic block 404 at one end of the dispersing rod 403 generates magnetic repulsion, causing the dispersing rod 403 to move outward and enter the conveying chamber 306 area. Under the action of the airflow ejected by the inclined air hole 304, it undergoes high-frequency vibration, further assisting in the loosening and unblocking of the fibers. Under normal circumstances, moisture is discharged through a moisture hole 4031 at one end of the dispersing rod 403. The moisture hole 4031 on the outer surface of the dispersing rod 403 is blocked by the sleeve 401, forming a thin water film on the surface of the normally conveyed fibers, reducing electrostatic adsorption. When blockage occurs, the dispersing rod 403 moves outward. At this time, the moisture hole 4031 on the outer surface of the dispersing rod 403 is unblocked, and multiple moisture holes 4031 simultaneously deliver moisture to the blocked area, increasing the fiber humidity in the blocked area, making it easier to separate and redisperse.

10. A method for conveying raw materials for nonwoven fabric processing, comprising a raw material conveying device for nonwoven fabric processing as described in any one of claims 1-9, characterized in that: Includes the following steps; S1: The two rotating tubes (204) and the dispersing tube (207) rotate inward simultaneously to mechanically disperse the clumps of nonwoven fabric fiber raw materials. When compressed air flows inside the dispersing tube (207), it is evenly sprayed out through the breathable membrane (208) to form a strong blowing effect on the fibers. The ion wind ball (210) will generate a large number of positive and negative ions that quickly attach to the fiber surface with the airflow, neutralizing the static charge accumulated by friction, which helps the fibers to loosen quickly. S2: The drive motor (303) drives the spiral conveyor (305) to rotate and convey the pre-dispersed fibers. Compressed air enters the cavity between the outer shell (1) and the conveyor cylinder (301) and is sprayed along the conveying direction through the inclined air hole (304) to prevent the fibers from getting stuck on the edge of the blades or accumulating at the bottom of the conveying cavity. An infrared detector is embedded inside the conveyor cylinder (301) to detect the change in the transmittance of infrared light in real time to determine whether there is fiber accumulation in the area. S3: When the electromagnet (402) inside the sleeve (401) is energized, the stirring rod (403) moves outward. Under the action of the airflow ejected by the inclined air hole (304), it vibrates at high frequency to assist in the loosening and unblocking of the fibers. The moisture hole (4031) opened on the outer surface of the stirring rod (403) provides moisture as needed, reducing the risk of electrostatic adsorption. At the same time, it softens the fiber surface, reduces entanglement, and makes it easier to separate and redisperse.
