Description

Technical Field

[0001] This invention relates to the field of rapier loom technology, specifically to a rapier loom with a waste selvage collection function. Background Technology

[0002] During the weaving process of a rapier loom, after the weft yarn is introduced into the warp layer, excess selvage is formed on both sides of the fabric. To ensure the normal operation of the loom, the stability of fabric quality, and the cleanliness of the production environment, this excess selvage needs to be treated to prevent it from scattering and entangled in equipment parts, causing loom malfunctions, or resulting in defects on the fabric surface.

[0003] In existing technologies, waste edge treatment often employs a combination of cutting and negative pressure suction. A waste edge cutting component trims the fabric edges, creating uniform short segments to prevent long strips from tangling around the equipment. The cut waste edges are then transferred using a negative pressure suction system. This system, powered by a fan, generates negative pressure to create airflow. This airflow carries the waste edges along suction pipes, ultimately transferring them to a collection box for final disposal.

[0004] The stable operation of a negative pressure suction system depends on a complete closed-loop airflow circulation. Its working logic is as follows: the fan generates negative pressure, the airflow carries the waste material into the collection box, and it is necessary to separate the air from the waste material so that the air can be discharged smoothly while the waste material is retained in the collection box to maintain the stability of the negative pressure in the pipeline and ensure the continuous effectiveness of the suction function.

[0005] However, existing waste edge collection devices have many problems that urgently need to be solved in practical applications. Due to the light nature of the waste edge itself, it is difficult for it to settle stably after entering the collection box. It tends to remain suspended and fly around repeatedly in the box, making it impossible to achieve uniform accumulation. This leads to a series of chain problems. Some of the suspended waste edge is drawn back into the suction pipe by the turbulent airflow in the box, forming waste edge backflow. The backflowing waste edge will gradually adhere to and accumulate on the inner wall of the pipe, reducing the flow cross-section of the pipe and increasing airflow resistance. This not only reduces suction efficiency but also gradually causes pipe blockage. Even the light waste edge may overflow and scatter around the loom and in the production workshop, polluting the production environment, increasing the workload of workshop cleaning, and adhering to the surface of the core moving parts of the loom, such as the rapier, beater reed, warp feed roller, and take-up roller. This can cause the parts to jam and wear more quickly. Long-term accumulation can also lead to parts jamming and breakage, causing unplanned downtime of the loom. This not only increases equipment maintenance costs but also disrupts the production rhythm. Meanwhile, scattered waste edges can easily become entangled and intertwined with normally woven fabrics, leading to breakage of warp and weft yarns, resulting in fabric defects, reducing fabric qualification rate, and increasing production losses. For chemical fiber waste edges, the flying and scattered short filaments also pose a safety hazard of contacting high-temperature parts of the loom and causing a fire, further increasing production risks. More critically, during gas-solid separation, suspended and airborne waste edges are continuously carried by the airflow and adhere to the surface of the filter screen, gradually forming a dense membrane. This can cause localized or even complete blockage of the filter screen pores. Once the filter screen is clogged, the air permeability resistance increases significantly, preventing smooth airflow and disrupting the pressure balance within the collection box. This leads to increased pressure within the collection box and a sudden drop in negative pressure within the pipes, ultimately causing the suction function to fail and preventing the proper transfer and collection of waste edges. After suction failure, the cut waste edges continue to accumulate in the cutting area, entangled in the cutting blades and shafts, resulting in increased cutting resistance and decreased precision. This leads to problems such as uncut or unevenly cut waste edges, creating a vicious cycle of "poor cutting → waste edge accumulation → suction failure → even worse cutting." Furthermore, long-term filter screen blockage and sudden pressure drops can cause abnormally high fan loads. Prolonged overload operation can easily cause overheating of the fan motor and impeller deformation, further exacerbating the risk of equipment failure.

[0006] The aforementioned problems overlap, severely disrupting the continuity of waste edge collection, interfering with the normal weaving process of the loom, and significantly reducing production efficiency. Therefore, there is an urgent need for a rapier loom with waste edge collection function that can controllably, orderly, and stably accumulate waste edges in the collection box, avoiding blockages and backflows at the suction port that affect equipment operation and cause a decrease in fabric qualification rate; reducing clogging of the filter screen and ensuring stable negative pressure, thereby improving the reliability of waste edge collection.

The housing has through holes at equal intervals. A vertical rod is slidably connected inside the housing. The vertical rod is hollow and has a spring-type insert on it. The bottom end of the vertical rod is fixedly connected to a material distribution plate, and a flow diffuser is fixedly connected to the center of the upper surface of the material distribution plate. The top of the collection bin is provided with a material inlet, and the flow diffuser and the material inlet are on the same vertical line. Blades are fixedly connected at equal intervals on the outer ring of the bulk material tray, and anti-backflow components are fixedly connected to the inner ring wall of the collection bin.

[0009] Preferably, the first component includes a set of shearing blades distributed on both sides of the fabric, the set of shearing blades being fixedly connected to the main machine, and a cover being provided on one side of the set of shearing blades. The cover is located at a position away from the fabric and is fixedly connected to the main machine.

[0010] As a preferred option, a third component is also included; The third component includes an annular groove formed on the inner wall of the collection bin, an auxiliary rod slidably connected in the annular groove, and the top end of the auxiliary rod being fixedly connected to the bottom surface of the bulk material tray; A support rod is fixedly connected to the bottom of the auxiliary rod, and a brush body is fixedly connected to the top of the support rod near the inner ring wall of the collection chamber.

[0017] Compared with the prior art, the present invention provides a rapier loom with a waste selvage collection function, which has the following beneficial effects: 1. The design of the second component in this invention provides the following advantages: Optimize airflow, stabilize the negative pressure environment, and improve the stability of waste edge collection: Unlike the defects of existing technologies where the airflow in the collection chamber is turbulent and the negative pressure is easily unbalanced, the second component can effectively disperse the airflow entering the collection chamber, avoiding the waste edge flying due to the direct airflow. At the same time, by reasonably guiding the material drop, the airflow and waste edge are separated in an orderly manner, ensuring smooth air discharge and stable settling of waste edge, thereby maintaining the closed-loop stability of the negative pressure suction system. This completely solves the problems of suction efficiency fluctuation and sudden drop in negative pressure caused by airflow turbulence in existing technologies, ensuring the continuity of the entire waste edge collection process. Avoiding waste edge backflow blockage and overflow, reducing equipment failure risk: Compared with the shortcomings of existing technology where waste edge is easily rolled back into the suction pipe by turbulent airflow, causing pipe blockage, and light waste edge is easy to overflow and scatter, the second component can effectively block the backflow of airflow and waste edge material, avoid the suction pipe being blocked, and prevent waste edge overflow from contaminating the core components of the loom. It fundamentally avoids the problems of waste edge adhering to the surface of moving parts such as rapier, beater reed, warp feed roller, and take-up roller, which can cause component movement jamming, accelerated wear, and component jamming and breakage due to long-term use. It reduces the number of unplanned downtimes of the loom, reduces equipment maintenance costs, and ensures the long-term stable operation of the loom. Protecting fabric weaving quality and reducing production losses: Unlike existing technologies where scattered waste edges can easily become entangled and intertwined with normally woven fabric, leading to warp and weft yarn breakage, fabric defects, and reduced fabric yield, the second component suppresses waste edge flying and prevents waste edge overflow and scattering, thus avoiding interference with the normal weaving process, reducing warp and weft yarn breakage and fabric defects, significantly improving fabric yield, reducing production losses caused by fabric defects, and improving production efficiency.

[0018] 2. The present invention, through the design of the diffuser and blades, can bring the following advantages: The auxiliary material distribution disc rotates smoothly and efficiently, reducing rotational resistance and improving rotational reliability: The conical diffuser adopts a conical structure, which can accurately and evenly disperse the airflow entering the collection chamber, avoiding concentrated airflow impact on a certain area, and providing a stable airflow foundation for the rotation of the material distribution disc; at the same time, after the airflow is dispersed by the diffuser, when it flows downward along the gap between the outer ring wall of the material distribution disc and the inner wall of the collection chamber, it will accurately act on the added blades, indirectly assisting the rotation of the material distribution disc with the thrust of the airflow, which can contribute to the drive, effectively make up for and avoid the defects of rotation jamming and uneven speed of the material distribution disc, ensuring the continuous and stable rotation of the material distribution disc, and providing a guarantee for the uniform transfer of waste edges; Optimizing airflow trajectory enhances material distribution and discharge effects, further suppressing waste edge scattering: The conical diffuser disperses the direct airflow into multiple uniform airflows. Combined with the rotation of the material distribution disc, this allows the airflow to diffuse more orderly towards the inner wall of the collection bin, avoiding waste edge suspension and scattering caused by turbulent airflow. Simultaneously, as the airflow acts on the blade-assisted material distribution disc, it drives the waste edge on the disc to rotate synchronously. Using centrifugal force, the waste edge is evenly thrown towards the inner wall of the collection bin, guiding it downward along the inner wall and achieving orderly transfer of the waste edge. Furthermore, when the airflow flows downward through the gaps, it creates a downward airflow thrust, assisting the waste edge to settle towards the bottom of the collection bin cavity, further suppressing waste edge scattering and solving the problems of easy suspension and unstable settling of waste edge in existing technologies. Indirectly enhancing negative pressure stability, reducing backflow risk, and further protecting equipment components: The conical diffuser disperses airflow, preventing negative pressure fluctuations caused by localized airflow turbulence. Combined with the orderly airflow brought about by the rotation of the blade-assisted material distribution disc, it ensures smooth airflow circulation within the collection bin and maintains a stable negative pressure environment. Simultaneously, the orderly downward airflow generates reverse thrust, effectively preventing waste edges from being rolled back by turbulent airflow. Combined with the rotation of the material distribution disc, it enables rapid transfer of waste edges, further preventing waste edges from flowing back into the suction pipe and causing blockage. It also prevents waste edges from overflowing and contaminating core moving parts such as the loom rapier and beater reed, indirectly extending the equipment's service life and reducing the probability of unplanned loom downtime.

[0019] 3. The design of the third component in this invention brings the following advantages: Effectively removes waste filaments adhering to the filter device, prevents the formation of a dense film, and ensures the normal operation of the filter device: Unlike existing technologies, where suspended and flying waste filaments tend to continuously adhere to the surface of the filter device's mesh plate, gradually forming a dense film that causes local or even overall blockage of the filter screen pores, the third component can perform timely and effective cleaning and maintenance of the filter device in the collection chamber. It can quickly peel off the waste filaments adhering to the filter screen, preventing the formation of a film from the root cause, ensuring that the filter screen pores remain unobstructed, and ensuring the stable operation of the gas-solid separation function of the filter device. This solves the core defects of existing technologies, such as easy clogging of the filter device and rapid decline in air permeability. Maintaining stable air permeability resistance of the filter device ensures air pressure balance in the collection chamber and stable negative pressure in the suction pipe: Compared with the existing technology where air permeability resistance increases significantly after the filter screen becomes clogged, leading to air not being able to escape smoothly, air pressure imbalance in the collection chamber, and a sudden drop in negative pressure in the suction pipe, the third component can keep the air permeability resistance of the filter device within a reasonable range by removing the waste filaments on the filter screen. This ensures that air can pass through the filter screen smoothly and escape smoothly, thereby stabilizing the air pressure balance in the collection chamber and avoiding situations where pressure rises or negative pressure drops suddenly. This provides a core guarantee for the closed-loop stable operation of the negative pressure suction system and completely solves the problem of negative pressure imbalance caused by filter screen clogging in the existing technology. Indirectly breaking the vicious cycle and protecting and reducing equipment failure risks: Compared to existing technologies where waste edges accumulate in the cutting area after suction failure, entanglement of blades and shafts leading to poor cutting, and sudden drops in negative pressure causing abnormal increases in fan load, motor overheating, and impeller deformation, the third component, by ensuring stable suction function, indirectly avoids the production risks caused by waste edge accumulation and backflow in the cutting area, protects the normal operation of cutting components, and prevents waste edges from overflowing and scattering around the loom, contaminating and adhering to core moving parts such as rapiers, beaters, warp rollers, and take-up rollers, reducing problems such as component jamming, wear, sticking, and breakage, and lowering the probability of unplanned loom downtime; at the same time, it prevents scattered waste edges from hooking and entangled with normally woven fabric, reducing warp and weft yarn breakage and fabric defects, improving fabric qualification rate, reducing production losses, and solving various production risks indirectly caused by filter clogging in existing technologies.

[0020] 4. The design of the auxiliary rod in this invention brings the following advantages: Achieving dual functions in a single component simplifies the overall structure and reduces manufacturing costs and assembly difficulty: Unlike existing technologies that require separate material tray rotation guide components, support rod components, and drive force transmission components, resulting in cumbersome component structures, numerous parts, and complex assembly processes, the auxiliary rod, through a single structural design, serves both as a guide for the rotation of the material tray and as a support rod and drive force transmission function. This eliminates the need for additional redundant components, effectively simplifying the overall structure of the second and third components, reducing parts processing and assembly costs, and minimizing errors during assembly, thereby improving the overall compactness of the waste edge collection device. Stable support and reliable force transmission ensure coordinated operation of the third and second components: As a supporting component of the support rod, the auxiliary rod provides stable support force, preventing deformation and swaying of the support rod, ensuring the working stability of the third component, and providing structural protection for the normal filtration and maintenance work of the third component; at the same time, the auxiliary rod can efficiently transmit the driving force from the drive wheel, stably transmitting the driving force to the material distribution disc, ensuring that the material distribution disc can rotate continuously and stably, realizing efficient transmission of driving force, avoiding the problem of weak rotation of the material distribution disc caused by poor transmission of driving force and excessive loss in the existing technology; in addition, the combination of its support and force transmission functions can realize the coordinated linkage between the second and third components, ensuring that the material distribution, airflow dispersion and filtration and maintenance work are carried out simultaneously and smoothly.

Detailed Implementation

[0023] 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.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Please refer to Figures 1 to 6As shown: To address the problems mentioned in the technical solutions, this invention provides a rapier loom with a waste selvage collection function, comprising: a main machine 1, fabric 2, and further comprising: a collection chamber 305 within a first component and a second component; The collection chamber 305 is disposed within the inner cavity of the main body 1; the second component includes a support ring 401 fixedly connected to the top wall of the inner cavity of the collection chamber 305, a drive wheel 402 symmetrically fixedly connected within the support ring 401, a driven ring 403 slidably connected within the support ring 401, and the drive wheel 402 and the driven ring 403 being attached to each other; a sleeve 404 is fixedly connected at equal intervals to the bottom surface of the driven ring 403, and through holes 405 are equidistantly opened on the sleeve 404, and a vertical [unclear] is slidably connected within the sleeve 404. The vertical rod 406 is hollow and has a spring-loaded insert 407 on it. A material distribution plate 408 is fixedly connected to the bottom of the vertical rod 406. A flow diffuser 409 is fixedly connected to the center of the upper surface of the material distribution plate 408. An inlet is opened at the top of the collection bin 305. The flow diffuser 409 and the inlet are on the same vertical line. Blades 410 are fixedly connected at equal intervals on the outer ring of the material distribution plate 408. An anti-backflow component 411 is fixedly connected to the inner ring wall of the collection bin 305. The first component includes shearing blade assembly 301 distributed on both sides of the fabric 2. The shearing blade assembly 301 is fixedly connected to the main machine 1. A cover 302 is provided on one side of the shearing blade assembly 301. The cover 302 is located away from the fabric 2 and is fixedly connected to the main machine 1. A suction pipe 303 is fixedly connected through the tail end of the cover 302. A negative pressure pipe 304 is fixedly connected through the suction end wall of the suction pipe 303. The end of the suction pipe 303 away from the cover 302 is connected to the collection chamber 305.

[0026] in: The first component is used to cut and transfer the waste edges of the fabric 2. Specifically, the shearing blade assembly 301 cuts the waste edges of the fabric 2 by opening and closing under electronic control, so that the waste edges are formed into uniform short segments, avoiding long strips of waste edges from tangling with the equipment. The cut waste edges are transferred to the collection chamber 305 through the cover 302 and the suction pipe 303 by a negative pressure suction system consisting of a negative pressure pipe 304 and a connected negative pressure machine.

[0027] The negative pressure pipe 304 is connected to an external negative pressure unit to provide negative pressure support for the waste transfer assembly consisting of the cover 302 and the suction pipe 303.

[0028] The bottom of the collection chamber 305 is equipped with a sealing plate, and staff will regularly collect and transfer the waste edges by opening and closing the sealing plate.

[0029] The second component is used to disperse the airflow entering the collection chamber 305 and guide the falling material, suppressing its flying and stabilizing the negative pressure; it effectively prevents the airflow and waste material from flowing back and clogging the conveying pipe (suction pipe 303), or even overflowing and contaminating the surface of the core moving parts of the loom such as the rapier, beater reed, warp feed roller, and take-up roller, causing the parts to jam, wear to increase, and eventually leading to the parts jamming and breaking, causing unplanned downtime of the loom; and it also prevents the scattered waste material from getting caught and tangled with the normally woven fabric, causing the warp and weft yarns to break, producing fabric defects, reducing the fabric qualification rate, and increasing production losses and other production risks.

[0030] The drive wheel 402 is driven by a motor, and its drive column surface is provided with a protrusion to increase the friction with the surface of the driven ring 403.

[0031] The driven ring 403 has a groove on its upper surface. The spacing of the groove matches the spacing of the protrusions on the drive wheel 402, thereby ensuring that the driven ring 403 can rotate effectively under the drive of the drive wheel 402.

[0032] The sleeve 404, through hole 405, vertical rod 406, and spring-type insert 407 form a rod height adjustable assembly.

[0033] The vertical rod 406 is hollow, and the pressable spring-type insert 407 on it is compatible with the through hole 405. In use, the distance between the material distribution plate 408 and the top inlet of the collection bin 305 can be indirectly adjusted by adjusting the spring-type insert 407 at different heights in the through hole 405 on the housing 404. This adapts to the speed at which the airflow carries the waste edge into and impacts the diffuser 409 under different negative pressures, improves the stability of waste edge collection, and avoids the situation where the waste edge material is too close to the top inlet of the collection bin 305, causing the waste edge material to be congested near the inlet and overflowing.

[0034] The bulk material tray 408 will rotate slowly under the drive of the drive wheel 402, the driven coil 403 and the adjustable rod height assembly.

[0035] The rotating material tray 408 can centrifugally throw off the waste material on it; at the same time, the material tray 408 is located at the upper part of the inner cavity of the collection bin 305, which can block the airflow from the bottom of the inner cavity of the collection bin 305, and prevent the airflow from carrying the waste material into the suction pipe 303 in the opposite direction, which would cause adverse effects.

[0036] The outer diameter of the bulk material tray 408 is smaller than the inner diameter of the collection bin 305.

[0037] The diffuser 409 is cone-shaped.

[0038] When the airflow carrying the waste edge enters the collection bin 305, the airflow will be dispersed under the influence of the conical diffuser 409, and centrifugally transferred with the assistance of the rotating material distribution plate 408. Finally, it will be turned by the obstruction of the inner wall of the collection bin 305 and transferred towards the bottom of the collection bin 305.

[0039] When the conical diffuser 409 disperses the airflow entering the collection chamber 305, the airflow, with the assistance of the material distribution plate 408, impacts the inner wall of the collection chamber 305 and moves towards the bottom of the inner cavity of the collection chamber 305. That is, when the airflow flows downward from the gap between the outer ring wall of the material distribution plate 408 and the inner wall of the collection chamber 305, the airflow will act on the blades 410, thereby indirectly assisting the rotation of the material distribution plate 408.

[0040] The anti-backflow component 411 can be used to prevent airflow from surging upward from the bottom of the collection chamber 305, reducing the situation where the airflow carries waste edges flying around in the collection chamber 305.

[0041] A further embodiment: Please refer to Figures 7 to 12 As shown: The third component includes an annular groove 501 formed on the inner wall of the collection chamber 305, an auxiliary rod 502 slidably connected in the annular groove 501, the top end of the auxiliary rod 502 being fixedly connected to the bottom surface of the material tray 408; a support rod 503 being fixedly connected to the bottom of the auxiliary rod 502, a brush body 504 being fixedly connected to the top of the support rod 503 near the inner wall of the collection chamber 305, cleaning needle plates 505 being fixedly connected at equal intervals on the inner wall of the collection chamber 305, the cleaning needle plates 505 and the brush body 504 being on the same horizontal plane, a secondary chamber 506 being fixedly connected to the outer surface of the collection chamber 305, a strip groove 507 being formed through the secondary chamber 506, a filter plate 508 being inserted into the strip groove 507, and a mesh plate 509 being fixedly connected to the secondary chamber 506.

[0042] in: The third component is used to clean and maintain the waste threads attached to the filter device on the collection chamber 305, so as to prevent the waste threads from forming a dense film on the filter device, causing partial or even complete blockage of the filter screen pores of the filter plate 508, which greatly increases the air permeability resistance, prevents air from being discharged smoothly, breaks the air pressure balance in the collection chamber 305, and then causes the pressure in the collection chamber 305 to rise and the negative pressure in the suction pipe 303 to drop sharply, ultimately causing the suction function to fail and the waste threads to be unable to be transferred and collected normally.

[0043] The straight bottom end of the auxiliary rod 502 slides into the annular groove 501.

[0044] The auxiliary rod 502 can provide rotational guidance for the rotation of the material tray 408; it can also be used as a support component for the support rod 503 and transmit the driving force brought by the drive wheel 402 that drives the material tray 408, thus realizing the dual function of one component.

[0045] The brush body 504 can be attached to clean the waste edges adhering to the screen plate 509, avoiding the long-term accumulation of waste edges forming a dense yarn film and disrupting the air pressure balance in the collection chamber 305.

[0046] The cleaning needle plate 505 consists of a fixed plate and a needle body, with the needle body fixed obliquely on the fixed plate. When the brush body 504, which has been cleaning the mesh plate 509, passes by, the needle body will remove the waste edge wires carried on the brush body 504, ensuring the effectiveness of its subsequent cleaning.

[0047] The outer wall of the auxiliary chamber 506 has through holes. After the air and waste are separated by the filter plate 508, the air can be smoothly discharged from the collection chamber 305 to maintain a stable negative pressure and ensure that the suction function is continuously effective.

[0048] The filter plate 508 is inserted into the auxiliary chamber 506 through the strip groove 507, and a sealing ring is provided on the filter plate 508 to ensure the sealing of the insertion strip groove 507 between it and the auxiliary chamber 506.

[0049] Filter plate 508 can be replaced depending on the specific situation and usage time.

[0050] The working process of all the content in the above embodiments is as follows: Waste edge cutting stage: When the main machine 1 is running, the shearing blade group 301 on both sides of the fabric 2 opens and closes under the electronic control, and cuts the waste edge of the fabric 2 into uniform short segments to avoid long strips of waste edge from tangling with the equipment.

[0051] Waste edge transfer stage: After cutting, the waste edge is negatively pressured by the negative pressure suction system composed of negative pressure pipe 304 and external negative pressure machine. Under the action of negative pressure, it enters the suction pipe 303 through the cover 302 and is transported to the collection chamber 305 through the suction pipe 303.

[0052] Airflow dispersion and waste edge guiding stage: The waste edge enters from the top inlet of the collection bin 305 with the airflow and first contacts the conical diffuser 409, where the airflow is evenly dispersed. At the same time, the drive wheel 402 drives the driven ring 403 to rotate, which in turn drives the housing 404, the vertical rod 406 and the material distribution plate 408 to rotate synchronously. The dispersed airflow acts on the blades 410 of the outer ring of the material distribution plate 408, which assists the material distribution plate 408 to rotate smoothly and efficiently. Under the centrifugal force of the rotation of the material distribution plate 408, the waste edge is thrown towards the inner ring wall of the collection bin 305 and moves downward along the inner wall. At this time, the anti-backflow component 411 of the inner ring wall of the collection bin 305 blocks the airflow from surging upward, preventing the waste edge from flowing back or flying away.

[0053] Filtration maintenance and air pressure stabilization stage: When the material tray 408 rotates, the auxiliary rod 502 on its bottom surface slides along the annular groove 501, driving the support rod 503 and brush body 504 to rotate synchronously. The brush body 504 attaches to the mesh plate 509 to clean the waste edge fibers attached to it, preventing the formation of a dense yarn film. When the brush body 504 passes through the cleaning needle plate 505, the needles of the cleaning needle plate 505 remove the waste edge fibers carried on the brush body 504, ensuring the cleaning effect. The airflow achieves gas-solid separation through the filter plate 508. The waste edge fibers are retained in the collection chamber 305, and the air is discharged through the holes in the outer wall of the auxiliary chamber 506, maintaining the air pressure balance and negative pressure stability in the collection chamber 305.
