Description

Technical Field

[0001] This invention relates to the field of dust removal technology in textile machinery, specifically a collection device and method for textile dust based on a textile machine. Background Technology

[0002] As the core equipment for processing raw materials such as yarn, silk, and hemp into fabric, the development of textile machinery has closely revolved around the characteristics of textile raw materials. From the ancient human-powered spinning wheels, spinning spools, and pedal looms to the modern highly automated mechanical looms and CNC automatic looms, the evolution of textile technology has always been committed to improving production efficiency and product quality. Given that ancient textiles mainly relied on natural short fibers such as wool, hemp, and cotton, while modern textile technology has widely covered various chemical fibers and blended materials, the structural design of equipment needs to be precisely adapted to the physical properties of different raw materials. Therefore, raw materials occupy a fundamental position in the textile technology system. The iterative upgrading of textile machinery is not only a change in power sources, but also a continuous response to the refinement and intelligence of fiber processing technology, aiming to meet the increasingly diversified needs of fabric production.

[0003] However, existing textile machines inevitably generate a large amount of fine lint and fiber impurities during high-speed operation. These suspended particles not only easily diffuse into the workshop air and harm the respiratory health of workers when inhaled, posing an occupational safety hazard, but also, if not cleaned in a timely and effective manner, the accumulated lint will adhere to the fabric surface, seriously reducing the smoothness of the fabric and the quality of the finished product. In addition, long-term accumulation of fiber dust may also penetrate into the precision mechanical parts, leading to increased transmission resistance, poor heat dissipation, or even short circuits, thereby accelerating equipment wear and shortening its service life. To address this, we propose a textile dust collection device and its collection method based on textile machines. Summary of the Invention

[0004] The purpose of this invention is to provide a collection device and method for textile dust based on a textile machine, so as to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions: A textile dust collection device based on a textile machine includes: a textile machine body and a mounting support frame, characterized in that: the textile machine body further includes: The collection component is mounted on the side of the textile machine body via the mounting support frame. The collection component is provided with a first dust collection chamber, a second dust collection chamber, and a dust collection chamber located below the first dust collection chamber and the second dust collection chamber. A first filter bag is provided in the first dust collection chamber, and a second filter bag is provided in the second dust collection chamber. A negative pressure drive component is provided on the collection component. A dust collection hood mechanism is located above the textile machine body. The dust collection hood mechanism includes a dust collection mounting base, a drive motor, a drive shaft, a cleaning scraper, and a first gear. The dust collection mounting base is mounted on the textile machine body, and the drive motor is mounted on one side of the dust collection mounting base and drives the cleaning scraper to perform a rotary scraping motion through the drive shaft. A dust collection assembly is disposed on the fabric output side of the textile machine body. The dust collection assembly includes an adjusting seat, a drive cylinder, a rotating shaft, a second gear, an electrostatic generator, and an electrostatic adsorption roller. The drive cylinder is mounted on the adjusting seat and is used to drive the rotating shaft and the electrostatic adsorption roller to move to adjust the working position. The electrostatic generator is electrically connected to the electrostatic adsorption roller. The second gear is driven by the first gear and is used to drive the rotating shaft and the electrostatic adsorption roller to rotate.

[0006] As a further preferred embodiment of this technical solution: the negative pressure drive assembly includes a negative pressure fan and a negative pressure impeller that is driven and connected to the power output end of the negative pressure fan, for forming a negative pressure airflow in the collection assembly. The collection assembly is connected to a dust collection pipe and an exhaust pipe. The exhaust pipe is connected to the air outlet end of the negative pressure drive assembly for discharging filtered clean airflow to the outside. The air inlet end of the dust collection pipe is connected to a dust guide hood, and the dust guide hood is fixed to the inside of the dust collection mounting base by a suspension mounting base.

[0007] As a further preferred embodiment of this technical solution: the first dust collection chamber and the second dust collection chamber are arranged in series along the airflow direction, and the first filter bag and the second filter bag together constitute a two-stage filtration structure for graded interception of textile lint and dust particles in the airflow.

[0008] As a further preferred embodiment of this technical solution: the dust collection mounting base is fixed to the top of the inner wall of the dust guide hood, the drive motor is fixedly mounted on the dust collection mounting base, the drive shaft is arranged vertically, the cleaning scraper is fixedly connected to the side wall of the drive shaft, and the outer edge of the cleaning scraper is in contact with the inner wall surface of the dust guide hood.

[0009] As a further preferred embodiment of this technical solution: the electrostatic adsorption roller includes a conductive base layer and a dielectric insulating layer covering the outer surface of the conductive base layer. The high-voltage output terminal of the electrostatic generator is electrically connected to the conductive base layer and is used to apply high-voltage static electricity to the conductive base layer, so that an electrostatic adsorption field is formed on the outer surface of the dielectric insulating layer to capture textile fibers and lint. The outer surface of the dielectric insulating layer is provided with a fine uneven microstructure to increase the effective contact area with suspended fibers and lint and enhance the electrostatic adsorption and capture effect.

[0010] As a further preferred embodiment of this technical solution: a conductive slip ring is provided between the rotating shaft and the electrostatic adsorption roller. The stator side of the conductive slip ring is electrically connected to the high-voltage output terminal of the electrostatic generator, and the rotor side of the conductive slip ring is electrically connected to the conductive base layer. This is used to continuously and stably transmit high-voltage static electricity when the electrostatic adsorption roller rotates with the rotating shaft.

[0011] As a further preferred embodiment of this technical solution: the rotating shaft is provided with an insulated wiring cavity, and a high-voltage lead is arranged in the insulated wiring cavity. One end of the high-voltage lead is connected to the high-voltage output terminal of the electrostatic generator, and the other end of the high-voltage lead is connected to the stator side of the conductive slip ring. An insulated support is fitted on the outer wall of the rotating shaft, and the electrostatic adsorption roller is rotatably assembled to the outside of the rotating shaft through the insulated support.

[0012] As a further preferred embodiment of this technical solution: multiple cleaning scrapers are provided, and the array of multiple cleaning scrapers is installed on the side wall of the drive shaft. The cleaning scrapers are made of conductive material and grounded. The ends of the cleaning scrapers abut against the outer surface of the dielectric insulating layer, which is used to discharge the residual static electricity on the surface of the dielectric insulating layer while scraping off the adsorbed lint fibers, thereby reducing the adhesion of the lint and facilitating its removal.

[0013] As a further preferred embodiment of this technical solution, the textile dust collection method based on a textile machine includes the following steps: S1. Negative pressure dust collection: Start the negative pressure drive component, and the negative pressure impeller will be driven by the negative pressure fan to form a negative pressure environment in the collection component; the lint and dust generated by the operation of the textile machine body will enter the dust guide hood with the airflow and be transported to the collection component through the dust collection pipe. S2, Two-stage filtration and dust removal: The dust-laden airflow flows sequentially through the first filter bag in the first dust collection chamber and the second filter bag in the second dust collection chamber, where lint and dust are intercepted in stages; the filtered airflow is discharged through the exhaust pipe, and the intercepted dust and lint settle into the dust collection chamber. S3, Electrostatic Adsorption Supplement: Start the electrostatic generator and apply high voltage static electricity to the conductive base layer of the electrostatic adsorption roller through high voltage output, so that a stable electrostatic field is formed on the surface of the dielectric insulating layer, adsorbing the fine fibers suspended on the surface and surrounding of the fabric. Adjust the electrostatic adsorption roller to the appropriate working position by driving the cylinder. S4. Linked Cleaning and Maintenance: Start the drive motor to rotate the cleaning scraper and remove dust accumulated on the inner wall of the dust guide hood and the electrostatic adsorption roller. At the same time, the second gear meshes with the first gear to drive the electrostatic adsorption roller to rotate, achieving uniform adsorption on the circumference. The cleaning scraper simultaneously removes the lint accumulated on the surface of the roller and releases the residual static electricity on the surface, allowing the lint to enter the dust collection pipeline with the airflow for collection.

[0014] The beneficial effects of this invention are: 1. This invention, by setting an electrostatic adsorption roller on the fabric output side and using a conductive slip ring to stably transmit high-voltage static electricity while the roller is continuously rotating, forms a uniform electrostatic field on the surface of the dielectric insulation layer, which can efficiently adsorb microfibers suspended on and around the fabric surface. This overcomes the shortcomings of simple negative pressure filtration in terms of the insufficient capture efficiency of ultrafine fibers. At the same time, a current-limiting resistor is connected in series in the high-voltage output circuit of the electrostatic generator, and an insulating mounting structure fixed to the bearing seat is set on the stator side of the conductive slip ring, which comprehensively ensures the stability of high-voltage static electricity transmission and the safety of equipment operation, and significantly improves the cleanliness of the fabric surface and the quality of the finished product.

[0015] 2. This invention integrates the drive motor, drive shaft, cleaning scraper, and first gear into a linked cleaning unit. The same drive shaft simultaneously drives the inner wall scraper of the dust guide hood and the surface scraper of the electrostatic adsorption roller to perform a rotary scraping motion, achieving a "one-shaft, two-clean" coordinated operation. The electrostatic adsorption roller continues to rotate through the meshing transmission of the first and second gears, requiring no additional power source. This results in a compact structure that is energy-efficient and highly effective. Furthermore, the cleaning scraper is made of conductive material and grounded, rapidly dissipating residual static electricity while scraping off the lint layer, reducing lint adhesion. Combined with the sealed bearing and oil seal at the drive shaft's penetration point to prevent air leakage in the negative pressure system, the detached lint is promptly sucked into the dust collection pipe under the action of negative pressure airflow, effectively avoiding secondary dust pollution.

[0016] 3. This invention, by setting up a collection assembly consisting of a negative pressure fan and two-stage filter bags, in conjunction with a dust guide hood located above the textile machine body, can form a stable and controllable negative pressure airflow field above the textile operation area. This allows large-particle lint and fine dust to be intercepted by filter bags of different precision levels, extending the service life of the filter bags and ensuring the cleanliness of the exhaust airflow. At the same time, by adjusting the distance between the electrostatic adsorption roller and the fabric through a drive cylinder, and in conjunction with the variable frequency speed control of the negative pressure fan, the adsorption distance and dust collection airflow can be flexibly adjusted according to different fabric types and production conditions, reducing occupational health risks.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-5 As shown, a textile dust collection device based on a textile machine includes a textile machine body 1 and a mounting support frame 21. The textile machine body 1 is equipped with a collection component 2, a dust collection hood mechanism 3 and a dust collection component 4. The collection component 2 serves as a negative pressure filtration core, the dust collection hood mechanism 3 serves as a top dust collection and cleaning unit, and the dust collection component 4 serves as a microfiber electrostatic adsorption unit on the fabric outlet side. The three components work together to achieve comprehensive collection and treatment of lint and dust of different particle sizes and sources in the textile workshop.

[0021] In specific implementation, the collection assembly 2 is fixedly mounted to the side of the textile machine body 1 via a mounting support frame 21. The interior of the collection assembly 2, along the airflow direction, sequentially comprises a first dust collection chamber 22, a second dust collection chamber 24, and a dust collection chamber 25 located below these two chambers. A first filter bag 221 is detachably installed in the first dust collection chamber 22, and a second filter bag 241 is detachably installed in the second dust collection chamber 24. A negative pressure drive assembly 23 is also provided on the top of the collection assembly 2. This negative pressure drive assembly 23 includes a negative pressure fan 231 and a negative pressure impeller 232 that is driven by the power output end of the negative pressure fan 231. After the negative pressure fan 231 starts, it drives the negative pressure impeller 232 to rotate at high speed, forming dust inside the collection assembly 2. In a continuous negative pressure environment, the dust-laden airflow enters the collection assembly 2 through the dust collection pipe 27 under the pressure difference. After passing through the first filter bag 221 and the second filter bag 241 in sequence, the clean airflow is discharged to the outside of the workshop through the exhaust pipe 26. The trapped lint and dust particles settle to the dust collection chamber 25 at the bottom under the action of gravity and are stored there. In this process, the first filter bag 221 is preferably made of needle-punched felt filter material with a large pore size to trap textile lint and coarse fibers with a large particle size. The second filter bag 241 is preferably made of membrane filter material with a small pore size to trap the fine dust particles remaining after filtration by the first filter bag 221. The two-stage filter bags are arranged in series to form a gradient filtration structure, which can significantly extend the filter bag cleaning cycle and reduce the dust concentration in the exhaust air.

[0022] As a technical optimization of the present invention, the air inlet end of the dust collection pipe 27 is connected to a dust guide hood 29. The dust guide hood 29 has a funnel-shaped structure, with its large-diameter end facing downwards and directly facing the working area of ​​the textile machine body 1. It is used to capture the lint and dust flying during the textile process to the maximum extent. The dust guide hood 29 is fixed to the inner side of the dust collection mounting base 31 by a suspension mounting base 28. The suspension mounting base 28 is preferably a rigid frame structure welded from channel steel and reinforcing ribs, which can effectively support the weight of the dust guide hood 29 and the internal dust collection hood mechanism 3 and resist the vibration caused by negative pressure fluctuations. It should be noted that a soft rubber skirt is added to the bottom opening edge of the dust guide hood 29 to be close to the upper surface of the textile machine body 1, reducing the amount of external air entrained, thereby increasing the effective air volume for dust collection.

[0023] In specific implementation, the dust collection hood mechanism 3 is located above the textile machine body 1 and inside the dust guide hood 29. The dust collection hood mechanism 3 includes a dust collection mounting base 31, a drive motor 32, a drive shaft 33, a cleaning scraper 34, and a first gear 35. The dust collection mounting base 31 is fixedly connected to the top of the inner wall of the dust guide hood 29. The drive motor 32 is fixedly mounted to one side of the dust collection mounting base 31 by bolts. The drive shaft 33 is arranged horizontally, with one end connected to the power output end of the drive motor 32 via a coupling, and the other end penetrating the interior of the dust guide hood 29 and extending to one side of the dust collection assembly 4. The drive shaft 33 guides the dust... A first set of scraper arms is fixedly installed on the shaft section inside the cover 29. The first set of scraper arms is an extension of the cleaning scraper 34. The outer edge of the first set of scraper arms is adapted to and fits the conical shape of the inner wall of the dust guide cover 29. It is used to scrape off the dust accumulated on the inner wall during the rotation. At the same time, a cleaning scraper 34 is fixedly installed at the end of the drive shaft 33 extending to the dust collection assembly 4. The end of the cleaning scraper 34 periodically abuts against the outer circumferential surface of the electrostatic adsorption roller 46 during the rotation of the drive shaft 33. When the drive motor 32 runs, the drive shaft 33 drives the two sets of scrapers to rotate and scrape synchronously, thereby achieving the linkage effect of "one shaft, two cleaning".

[0024] As a technical optimization of the present invention, a first gear 35 is fixedly installed in the middle section or extension end of the drive shaft 33. The first gear 35 corresponds in space to the second gear 44 provided at the end of the rotating shaft 43 in the subsequent dust collection assembly 4 and forms a meshing transmission cooperation. The gear ratio of the first gear 35 and the second gear 44 is set according to the actual required speed matching relationship so that the speed of the electrostatic adsorption roller 46 is slightly higher than or equal to the speed of the cleaning scraper 34, ensuring that each area of ​​the surface of the electrostatic adsorption roller 46 can obtain sufficient adsorption and cleaning. It should be noted that when the drive shaft 33 passes through the dust guide hood 29 laterally, a sealed bearing and a graphite packing sealing structure are provided at the penetration point between the drive shaft 33 and the wall of the dust guide hood 29 to prevent a large amount of external air from being sucked in from the unsealed shaft hole and affecting the dust collection negative pressure.

[0025] In specific implementation, the dust collection component 4 is set on the fabric output side of the textile machine body 1, and is used to electrostatically adsorb and capture the fine fibers suspended on the surface of the woven fabric and in the surrounding environment. The dust collection component 4 includes an adjusting seat 41, a driving cylinder 42, a rotating shaft 43, a second gear 44, an electrostatic generator 45, and an electrostatic adsorption roller 46. The adjusting seat 41 is fixedly installed on the frame on the fabric output side of the textile machine body 1. The cylinder end of the driving cylinder 42 is installed on the adjusting seat 41 through a hinge seat. The piston rod end of the driving cylinder 42 is rotatably connected to the end of the rotating shaft 43 through a connector. Under the pushing action of the driving cylinder 42, the rotating shaft 43 and the electrostatic adsorption roller 46 assembled outside it can move relative to the fabric surface, thereby adjusting the gap distance between the electrostatic adsorption roller 46 and the fabric to adapt to the dust removal needs of fabrics of different thicknesses.

[0026] As a technical optimization of the present invention, the electrostatic adsorption roller 46 includes a conductive base layer and a dielectric insulating layer covering the outer surface of the conductive base layer. The conductive base layer is a hollow cylindrical structure made of stainless steel or copper metal material. The dielectric insulating layer is made of polytetrafluoroethylene or polyimide and other polymer insulating materials and is tightly wrapped around the outside of the conductive base layer in the form of a heat-shrink tubing. The high-voltage output terminal of the electrostatic generator 45 is electrically connected to the conductive base layer through a high-voltage wire. When the electrostatic generator 45 is started, a high-voltage static electricity of 5kV to 30kV is applied to the conductive base layer, so that a uniform and stable electrostatic field is formed on the outer surface of the dielectric insulating layer. When the microfibers suspended in the air pass through the electrostatic field area, they are polarized and adsorbed onto the surface of the dielectric insulating layer. In order to further enhance the adsorption effect, the outer surface of the dielectric insulating layer is provided with a fine uneven microstructure by knurling or etching process. The roughness Ra value of the uneven microstructure is preferably 3.2μm to 12.5μm, which can significantly increase the effective contact area with suspended fibers and lint, and enhance the electrostatic adsorption and capture effect.

[0027] In specific implementation, a conductive slip ring is provided between the rotating shaft 43 and the electrostatic adsorption roller 46. The stator side of the conductive slip ring is fixed to the part of the rotating shaft 43 that does not rotate with the roller by a bracket, and the terminal on the stator side is electrically connected to the high-voltage output terminal of the electrostatic generator 45 through a high-voltage lead. The rotor side of the conductive slip ring is embedded inside the end cap of the electrostatic adsorption roller 46, and the terminal on the rotor side is electrically connected to the conductive base layer through a conductive spring contact that abuts against the conductive base layer. When the electrostatic adsorption roller 46 rotates continuously with the rotating shaft 43, the conductive slip ring can continuously and stably transmit high-voltage static electricity from the stationary stator side to the rotating rotor side, ensuring that the surface electrostatic field strength of the electrostatic adsorption roller 46 remains stable during rotation. Furthermore... An insulated wiring cavity is provided axially inside the rotating shaft 43. A high-voltage lead is arranged in the insulated wiring cavity. One end of the high-voltage lead passes through the inlet of the insulated wiring cavity and is connected to the high-voltage output terminal of the electrostatic generator 45. The other end of the high-voltage lead passes through the outlet of the insulated wiring cavity and is connected to the stator side of the conductive slip ring. The inner wall of the insulated wiring cavity is also coated with an organosilicon insulating coating to prevent the high-voltage lead from breaking down and discharging with the metal inner wall of the rotating shaft 43 during movement. An insulating support seat is also fitted on the outer wall of the rotating shaft 43. The insulating support seat is preferably made of ceramic or polyetheretherketone material. The electrostatic adsorption roller 46 is rotatably mounted on the outside of the insulating support seat through rolling bearings set in both ends of the roller, thereby realizing the free rotation of the electrostatic adsorption roller 46 relative to the rotating shaft 43.

[0028] As a more preferred embodiment of the present invention, the cleaning scraper 34 is made of conductive material, preferably stainless steel or galvanized steel. The cleaning scraper 34 is reliably grounded by a soft copper braided wire. During the rotation of the drive shaft 33, the end of the cleaning scraper 34 periodically contacts the outer surface of the dielectric insulating layer of the electrostatic adsorption roller 46. The contact pressure is controlled by adjusting the installation angle and length of the cleaning scraper 34. When the lint fiber layer adsorbed on the surface of the electrostatic adsorption roller 46 reaches a certain thickness, the end of the cleaning scraper 34 first physically scrapes off the adsorbed layer. At the same time, during the scraping process, the grounded cleaning scraper 34 can quickly release the residual static electricity on the surface of the dielectric insulating layer, which greatly reduces the electrostatic adsorption force between the lint fiber and the roller surface. Under the combined action of its own weight and the negative pressure airflow in the dust collection pipe 27, the lint is smoothly sucked into the dust collection pipe and finally enters the collection assembly 2 for collection.

[0029] It should be noted that the contact position between the cleaning scraper 34 and the electrostatic adsorption roller 46 is preferably set on the side of the electrostatic adsorption roller 46 facing away from the fabric, that is, on the upper side away from the fabric output direction, so as to avoid the scraping action interfering with the adsorption effect of the electrostatic adsorption roller 46 on the area facing the fabric.

[0030] In use, the present invention firstly fixes the collection component 2 to the side of the textile machine body 1 via the mounting support frame 21, fixes the dust guide hood 29 above the textile machine body 1 via the hanging mounting seat 28, installs the dust collection component 4 on the fabric output side frame, and completes all electrical wiring and air circuit connections. The negative pressure fan 231 is started, and the negative pressure impeller 232 rotates at high speed, creating negative pressure within the collection component 2. The lint and dust generated during the operation of the textile machine body 1 are carried by the induced airflow through the dust guide hood 29 into the dust collection pipe 27, and then into the first dust collection chamber 22. Larger lint particles are trapped by the first filter bag 221, and the airflow containing fine dust continues into the second dust collection chamber 24, where tiny dust particles are trapped by the second filter bag 241. The clean airflow is discharged from the workshop via the exhaust pipe 26. During the negative pressure dust collection process, the electrostatic generator 45 is started, and the high voltage static electricity is stably transmitted to the conductive base layer of the electrostatic adsorption roller 46 through the conductive slip ring, forming an electrostatic field on the surface of the dielectric insulating layer, which adsorbs and collects the fine fibers suspended on the surface and surrounding of the fabric on the fabric side. Then, the drive motor 32 is started, and the drive shaft 33 drives the scraper arm in the dust guide hood 29 to rotate continuously, scraping off the dust accumulated on the inner wall to keep the airflow channel smooth. At the same time, the first gear 35 at the end of the drive shaft 33 drives the second gear 44 to rotate, so that the electrostatic adsorption roller 46 rotates continuously to ensure that its circumferential surface is uniformly adsorbed with lint. Meanwhile, the cleaning scraper 34 at the end of the drive shaft 33 periodically contacts the surface of the electrostatic adsorption roller 46 during the rotation, scraping off the rich lint layer and simultaneously releasing the residual static electricity. The scraped-off lint enters the collection assembly 2 through the dust collection pipe 27 with the negative pressure airflow and finally settles in the dust collection chamber 25. Operators can adjust the distance between the electrostatic adsorption roller 46 and the fabric by driving cylinder 42 according to the fabric type and production conditions, and control the dust collection air volume by frequency conversion adjustment of negative pressure fan 231 to achieve flexible adaptation. In the whole process, the scraping action of cleaning scraper 34, the rotation action of electrostatic adsorption roller 46 and the negative pressure dust collection action form a stable coordinated operation cycle through mechanical linkage and airflow coupling. There is no need for frequent manual intervention. Through the multiple coordinated effects of negative pressure filtration and collection, electrostatic adsorption and replenishment and linkage cleaning and maintenance, lint and dust in the textile workshop can be efficiently removed, significantly improving the working environment and fabric quality.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

9. A method for collecting textile dust based on a textile machine, comprising the textile dust collection device based on a textile machine as described in any one of claims 1 to 8, characterized in that, Includes the following steps: S1, Negative pressure dust collection: Start the negative pressure drive component (23), drive the negative pressure impeller (232) to run through the negative pressure fan (231), and form a negative pressure environment in the collection component (2); the lint and dust generated by the operation of the textile machine body (1) enter the dust guide hood (29) with the airflow, and are transported to the collection component (2) through the dust collection pipe (27); S2, Two-stage filtration and dust removal: The dust-laden airflow flows sequentially through the first filter bag (221) in the first dust collection chamber (22) and the second filter bag (241) in the second dust collection chamber (24), where lint and dust are intercepted in stages; the filtered airflow is discharged through the exhaust pipe (26), and the intercepted dust and lint settle into the dust collection chamber (25). S3, electrostatic adsorption replenishment: Start the electrostatic generator (45) and apply high voltage static electricity to the conductive base layer of the electrostatic adsorption roller (46) through high voltage output, so that a stable electrostatic field is formed on the surface of the dielectric insulating layer, adsorbing the fine fibers suspended on the surface and surrounding of the fabric.
