Description

Technical Field

[0001] The invention relates to the technical field of textile dust separation, in particular to a textile dust collecting device for textile use. Background Art

[0002] In the textile industry, textile products are easily produced during production and processing. A lot of textile dust such as flying catkins and cotton wool is generated. This kind of textile dust will float in the air due to its light weight, seriously endangering the health of workshop workers. In addition, a large amount of textile dust floating in the air is flammable. Once burned, it will cause serious safety accidents. Therefore, it is necessary to separate and remove the textile dust in the air.

[0003] In the prior art, textile dust is generally separated from the air through a filter assembly to achieve the purpose of removing textile dust. However, since the filter assembly will become clogged after being used for a long time and affect the subsequent filtering effect, the staff is required to regularly disassemble the filter assembly for processing. Since the textile dust content in the air is random, the time of large-scale filter blockage is also random, and the staff cannot deal with the filter assembly in time.

[0004] In response to the above technical problems, the present invention discloses a textile dust collection device for textile use. The present invention has the advantages of separating textile dust in the air from the air through a filter assembly, and can perform self-cleaning treatment according to the blockage condition of the filter assembly, so that the blockage of the filter assembly can be dealt with in time. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a textile dust collection device for textile use, so as to solve the technical problems in the prior art that, when filtering and separating textile dust in the air, the filter assembly will become clogged after being used for a long time, affecting the subsequent filtering effect, and the staff need to regularly disassemble the filter assembly for processing, while the textile dust content in the air is random, and the staff cannot process the filter assembly in time. The present invention has the advantages that when separating the textile dust in the air from the air through the filter assembly, the filter assembly can be self-cleaned according to the blockage condition of the filter assembly, so that the blockage of the filter assembly can be processed in time.

[0006] The present invention is implemented by the following technical scheme: The present invention discloses a textile dust collection device for textile use, comprising a collection box, one end of the collection box is provided with an exhaust port, the exhaust port is connected to a fan assembly, the other end of the collection box is provided with an air inlet, and the air inlet is provided with a filter assembly;

[0007] The filter screen assembly includes a fixed frame and a filter screen body. The fixed frame is slidably arranged inside the collection box. The outer wall of the fixed frame is in contact with and slidably engaged with the inner wall of the collection box. Inside the fixed frame, there are multiple fan-shaped filter screen bodies, and the multiple filter screen bodies are arranged in a circular array with the center of the fixed frame as the center of the circle. A central shaft is fixedly arranged at the center of the fixed frame;

[0008] A rotating shaft is concentrically and rotatably arranged inside the central shaft. Both ends of the rotating shaft extend to both ends of the central shaft. On the outer wall of the end of the rotating shaft facing the air inlet direction, there are fixed rods, and there are multiple fixed rods. The fixed rods are arranged in a circular array on the outer wall of the rotating shaft with the center of the rotating shaft as the center. On the side of the fixed rod facing the filter screen body, there are bristles, and one end of the bristles facing the filter screen body contacts the surface of the filter screen body;

[0009] The rotation of the rotating shaft is driven by a conversion component, and the conversion component is used to convert the linear motion of the filter screen body into the circumferential rotation of the rotating shaft.

[0010] Furthermore, a collection groove is formed at the partition between two adjacent filter screen bodies on the fixed frame, and a collection bin is also fixedly arranged at the partition between two adjacent filter screen bodies. The collection bin is arranged on the fixed frame facing the air outlet direction. The inside of the collection bin is communicated with the inside of the collection groove. One end of the collection bin facing the inner wall of the collection box is open, and a dust removal port is formed at the position of the collection box wall corresponding to the open end of the collection bin.

[0011] Furthermore, the conversion component includes a limit ring, a connecting shaft, a plugging shaft, a plugging pipe, a clamping part and a guiding groove. The limit ring is fixedly arranged inside the collection box through a support rod, and the connecting shaft is slidably inserted inside the limit ring. Positioning discs are arranged at both ends of the connecting shaft to limit the movement of the connecting shaft. A support spring is sleeved outside the connecting shaft to rebound the connecting shaft towards the filter screen body direction. A plugging pipe is also arranged between the limit ring and the filter screen assembly, and the plugging pipe is fixedly arranged inside the collection box through a support rod. A plugging shaft is slidably inserted inside the plugging pipe, and the outer wall of the plugging shaft is in contact with the inner wall of the plugging pipe. The plugging shaft is rotatably connected to and concentric with the positioning disc at one end of the connecting shaft facing the filter screen assembly. One end of the plugging shaft facing the filter screen assembly is fixedly connected to the rotating shaft and is concentric with each other. A clamping part is fixedly arranged on the outer circumferential wall of one end of the plugging shaft. A guiding groove is formed on the inner wall of the plugging pipe. The clamping part on the outer wall of the plugging shaft is movably inserted inside the guiding groove. The guiding groove extends from one end of the plugging pipe to the other end of the plugging pipe, and the guiding groove is in an inclined state.

[0012] Furthermore, the clamping part and the guiding groove are configured such that when the plugging shaft axially inserts and moves inside the plugging pipe, the clamping part moves along the guiding groove to drive the plugging shaft to rotate while axially moving.

[0013] Furthermore, a torsion spring is arranged at the rotating shaft, and the torsion spring is used to store energy for the rotation of the rotating shaft.

[0014] Further, the rotating shaft includes an upper shaft and a lower shaft which are concentrically arranged. Both the upper shaft and the lower shaft are rotatably connected to the central shaft. The lower shaft is rotatably connected to the upper shaft through a support shaft. The upper shaft and the lower shaft are elastically connected by a torsion spring, and the torsion spring is sleeved outside the support shaft. A clamping component is arranged at the upper shaft for circumferentially limiting the upper shaft.

[0015] Further, the clamping component includes a plugging hole, a locking shaft, a control cavity, a connecting hole, a locking jack, a locking plug shaft, a return spring, a pull rope and a circumferential limiting component. An upper part inside the upper shaft is provided with the plugging hole. The upper shaft is rotatably sleeved outside the locking shaft through the plugging hole, and the locking shaft can only rotate inside the plugging hole and cannot move axially. One end of the locking shaft extends outside the upper shaft. A control cavity is also provided inside the locking shaft. A locking jack is provided on the inner wall of the plugging hole. A connecting hole is provided at a position corresponding to the locking jack on the outer wall of the locking shaft. A locking plug shaft is slidably inserted inside the connecting hole, and one end of the locking plug shaft is inserted inside the locking jack. The other end of the locking plug shaft extends into the control cavity. A return spring is arranged at one end of the locking plug shaft located inside the control cavity. The return spring is used to bounce the locking plug shaft towards the locking jack. One end of the return spring is provided with a guide tube, and one end of the guide tube is fixedly connected to the inner wall of the control cavity. A pull rope is fixedly arranged at one end of the locking plug shaft located inside the control cavity, and the other end of the pull rope passes through the guide tube and is guided by a guide post inside the guide tube and extends outside the locking shaft. A circumferential limiting component is fixedly arranged at one end of the locking shaft located outside the plugging hole.

[0016] Further, the circumferential limiting component includes a circumferential limiting rod and a limiting sleeve. The circumferential limiting rod is square-shaped, and the inner hole of the limiting sleeve is also square-shaped. The circumferential limiting rod is slidably inserted inside the limiting sleeve, and the limiting sleeve is fixedly arranged at the air inlet of the collection box through a support rod. One end of the pull rope located outside the locking shaft is fixedly connected to the limiting sleeve, and the pull rope is in a slack state.

[0017] The present invention has the following advantages:

[0018] The present invention sets up a filter screen assembly and sets the filter screen assembly to be in a slidable state. Then, during actual operation, when the filter screen assembly is severely blocked, the filter screen body cannot ventilate. Due to the increased pressure difference between the upper and lower parts, the fixing plate is sucked by the suction force of the fan assembly, causing the filter screen assembly to move towards the air outlet direction. Furthermore, through the conversion assembly, the movement of the filter screen assembly is converted into the rotation of the rotating shaft. When the rotating shaft rotates, the filter screen surface is cleaned by the brush bristles, enabling the filter screen assembly to perform self-cleaning according to its own blockage situation. Additionally, by setting a torsion spring, energy is stored through the cooperation of the torsion spring and the clamping assembly. When the filter screen body is blocked and the blockage area gradually increases, the filter screen body will also gradually move towards the air outlet direction as the pressure difference increases. When the rotation angle of the rotating shaft is greater than the angle of the sector-shaped filter screen body, the torsion spring releases, causing the fixed rod to rotate. The fixed rod drives the brush bristles to comprehensively clean the sector-shaped filter screen body, improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The embodiments of the present invention will be described in detail below. These embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, terms indicating orientation or position relationship such as "front", "rear", "left", "right", etc. are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0030] Embodiment 1

[0031] Embodiment 1 discloses a textile dust collection device for textile use, as Figures 1 - 9 shown, including a collection box 1, as Figure 1 and Figure 2 shown, the collection box 1 can be installed at the textile machine through the bracket 2, and then the textile dust such as flying flocs generated by the textile machine can be filtered and collected through the collection box 1;

[0032] One end of the collection box 1 is provided with a fan assembly 3. Specifically, an air outlet 5 is opened at one end of the collection box 1, and the fan assembly 3 is connected to the air outlet 5 through a flange;

[0033] On the other end of the collection box 1, an air inlet 4 is provided. The air inlet 4 is in communication with the air outlet 5, and a filter assembly 6 is provided at the air inlet 4. When the fan assembly 3 is turned on, the fan assembly 3 can suck external air from the air inlet and discharge it through the air outlet 5. When the external air enters through the air inlet 4, it will be filtered by the filter assembly 6, thereby separating the textile dust in the air from the air, causing the textile dust to be intercepted on the surface of the filter assembly 6, and the separated air is discharged through the air outlet 5;

[0034] Considering that after long-term operation, a large amount of textile dust will accumulate on the surface of the filter assembly 6, and the textile dust will wind and accumulate to cover and block the filter holes, reducing the ventilation rate of the filter assembly 6 and thus reducing the filtering effect. Therefore, the filter assembly 6 needs to be cleaned in a timely manner;

[0035] In order to clean the filter assembly 6, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 shown, the filter assembly 6 is specifically set to include a fixed frame 601 and a filter mesh body 602. The fixed frame 601 is arranged inside the collection box 1. The fixed frame 601 includes a fixing plate 611, a sector-shaped groove 612, and a central shaft 613. Among them, the fixing plate 611 is arranged inside the collection box 1, and a sector-shaped groove 612 is formed inside the fixing plate 611. A plurality of sector-shaped grooves 612 are provided, and the plurality of sector-shaped grooves 612 are arranged in a circular array with the central position of the fixing plate 611 as the center. A central shaft 613 is also fixedly arranged at the central position of the fixing plate 611. A filter mesh body 602 is fixedly arranged inside each sector-shaped groove 612. The filter mesh body 602 is also set to be sector-shaped. In this embodiment, four sector-shaped grooves 612 are provided;

[0036] A rotating shaft 614 is rotatably arranged concentrically inside the central shaft 613. The two ends of the rotating shaft 614 respectively extend to the two ends of the central shaft 613. A fixing rod 7 is fixedly arranged on the outer circumferential wall of one end of the rotating shaft 614 in the direction of the air inlet 4. A plurality of fixing rods 7 are provided, and the number of fixing rods 7 is the same as that of the sector-shaped grooves 612, so that one fixing rod 7 can correspond to one sector-shaped groove 612. In this embodiment, four fixing rods 7 are provided, and the four fixing rods 7 are arranged in a circular array on the outer wall of the rotating shaft 614 with the center of the rotating shaft 614 as the center. A plurality of bristles 8 are fixedly arranged on the four fixing rods 7 facing the direction of the filter mesh body 602, and the end of the bristle 8 facing the filter mesh body 602 is in contact with the surface of the filter mesh body 602;

[0037] Therefore, when the filter screen body 602 needs to be cleaned, the rotating shaft 614 is rotated. The rotation of the rotating shaft 614 drives the fixing rod 7 to rotate, and then each fixing rod 7 drives the brush hair 8 to brush and transfer the textile dust such as flying fluffs on the surface of the corresponding sector of the filter screen body 602, so that the textile dust covering the filter holes on the surface of the filter screen body 602 is scraped off, thereby enabling the filter screen body 602 to ventilate again. It should be noted that by scraping the textile dust on the surface of the filter screen body 602 with the brush hair 8, in other embodiments, the brush hair 8 can also be set as a scraper, and then the textile dust on the surface of the filter screen body 602 is scraped off by the scraper;

[0038] In order to collect the textile dust after cleaning, and thus prevent the flying fluffs after cleaning from continuing to fall on the surface of the filter screen body 602 and re-blocking the filter screen body 602, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 shown, a collection groove 9 is formed at the partition between two adjacent sector grooves 612 on the fixing plate 611. The collection groove 9 penetrates through the upper and lower end faces of the fixing plate 611. In addition, a collection bin 10 is fixedly arranged at the partition between each adjacent sector groove 612, and the collection bin 10 is arranged in the direction of the air outlet 5 of the fixing plate 611. The inside of the collection bin 10 is communicated with the inside of the collection groove 9. One end of the collection bin 10 is fixedly connected to the central shaft 613. One end of the collection bin 10 facing the inner wall of the collection box 1 is an open end, and a dust taking port 11 is formed at the position of the box wall of the collection box 1 corresponding to the open end. The open end is communicated with the dust taking port 11. In addition, it should also be noted that the fixing rod 7 is normally aligned parallel to the collection groove 9. Therefore, when the rotating shaft 614 rotates, the rotating shaft 614 is rotated by an angle, so that the rotating shaft 614 drives the fixing rod 7 to move from the mutually parallel collection groove 9 to the next collection groove 9. In this embodiment, four fixing rods 7 are arranged in a circular array. Therefore, the rotation angle of the rotating shaft 614 is 90 degrees. Then, the rotating shaft 614 is rotated 90 degrees, so that the fixing rod 7 drives the brush hair 8 to move to the next collection groove 9. During the movement of the brush hair 8, the textile dust on the surface of the sector-shaped filter screen body 602 can be brushed and transferred into the interior of the collection groove 9. Thus, by rotating the rotating shaft 614 to drive the fixing rod 7 and the brush hair 8 to displace, the textile dust on the surface of the filter screen body 602 is brushed and the textile dust is swept into the interior of the collection groove 9. Then, the textile dust enters the interior of the collection bin 10 from the collection groove 9, and the staff can regularly take out the textile dust inside the collection bin 10 through the dust taking port 11;

[0039] In order to improve the simplicity of cleaning the filter screen body 602, so that the cleaning of the filter screen body 602 can be self-cleaned without the need for the staff to start it. The cleaning of the filter screen body 602 can be started according to its own blockage situation, as Figure 1 、Figure 2 , Figure 4 , Figure 5 As shown in Figure 2 , Figure 4 , and Figure 5 , the cross-sectional shape of the fixed frame 601 is the same as that of the collection box 1. The cross-sectional shapes of both the fixed frame 601 and the collection box 1 are set to be square. The outer walls of the four sides of the fixing plate 611 are respectively in contact with and slidably engaged with the inner walls of the four sides of the collection box 1. To improve the sealing performance, a sealing gasket can be selected to be provided on the outer walls of the four sides of the fixing plate 611, thereby improving the sliding sealing performance, and further enabling the fixed frame 601 to slide within the inner cavity of the collection box 1. Correspondingly, one end of the collection bin 10 facing the inner wall of the collection box 1 is also in contact with and slidably engaged with the inner wall of the collection box 1. By means of the fixed frame 601, the filter assembly 6 is set to be movable within the inner cavity of the collection box 1. Furthermore, after the filter element 602 becomes blocked, and as the blockage worsens, the air permeability of the filter element 602 decreases, resulting in a larger pressure difference between the upper and lower sides. The suction force of the fan assembly 3 can suck the fixed frame 601 and cause the fixed frame 601 to move towards the air outlet 5;

[0040] When the filter element 602 is blocked and the filter assembly 6 is displaced by the suction force of the fan assembly 3, the rotation of the rotating shaft 614 is set to be driven by the displacement of the filter assembly 6, and specifically, the displacement of the filter assembly 6 is converted into the rotation of the rotating shaft 614 through the conversion assembly 12;

[0041] More specifically, as Figure 4 , Figure 5 and Figure 7As shown in the figure, the conversion component 12 includes a limit ring 121, a connecting shaft 122, a plug shaft 123, a plugging pipe 124, a clamping member 125, and a guide groove 126. Among them, the limit ring 121 is arranged between the air outlet 5 and the fixing plate 611. A support rod 13 is fixedly arranged on the outer circumferential outer wall of the limit ring 121, and a plurality of support rods 13 are provided. The other end of the support rod 13 is fixedly connected to the inner wall of the collection box 1. The connecting shaft 122 is slidably inserted into the limit ring 121. Positioning disks 15 are fixedly arranged at both ends of the connecting shaft 122 respectively. The insertion of the connecting shaft 122 and the limit ring 121 is limited by the positioning disks 15. A support spring 14 is arranged between the two positioning disks 15, and the support spring 14 is sleeved outside the connecting shaft 122. One end of the support spring 14 abuts against the positioning disk 15, and the other end abuts against the limit ring 121. Thus, the connecting shaft 122 is rebounded towards the filter screen body 602 by the support spring 14. A plugging pipe 124 is further arranged between the limit ring 121 and the filter screen assembly 6, and the plugging pipe 124 and the positioning disk 15 are both fixedly arranged inside the collection box 1 through the support rod 13. A plug shaft 123 is slidably inserted into the plugging pipe 124, and the outer wall of the plug shaft 123 fits with the inner wall of the plugging pipe 124. One end of the plug shaft 123 is rotatably connected to the positioning disk 15 at one end of the connecting shaft 122 facing the filter screen assembly 6, and the plug shaft 123 and the connecting shaft 122 are concentrically arranged. One end of the plug shaft 123 facing the filter screen assembly 6 is fixedly connected concentrically to one end of the rotating shaft 614. A clamping member 125 is fixedly arranged on the outer circumferential outer wall of one end of the plug shaft 123. The clamping member 125 is specifically a cylindrical shaft body. A guide groove 126 is opened on the inner wall of the plugging pipe 124, and the guide groove 126 extends from one end of the plugging pipe 124 to the other end of the plugging pipe 124. The guide groove 126 is in an inclined state;

[0042] Specifically, the guide groove 126 extends along the circumferential direction of the plugging pipe 124 while extending along the axis of the plugging pipe 124, and then extends to the opening at the other end of the plugging pipe 124. The two ends of the guide groove 126 are vertically staggered, and the two ends of the guide groove 126 are at different positions on the circumferential line of the plugging pipe 124. The clamping member 125 on the outer wall of the plug shaft 123 is movably inserted into the guide groove 126. When the plug shaft 123 is axially inserted and moved along the inside of the plugging pipe 124, the setting of the clamping member 125 and the guide groove 126 can make the plug shaft 123 rotate while axially moving, thereby realizing the conversion of the longitudinal movement of the filter screen assembly 6 into the rotation of the rotating shaft 614;

[0043] Through the above settings, the displacement of the filter screen assembly 6 is limited by the cooperation of the connecting shaft 122 and the limit ring 121, and the reset of the filter screen assembly 6 is elastically forced by the setting of the support spring 14;

[0044] Therefore, after the filter screen body 602 is severely blocked, the filter screen body 602 cannot pass air. Due to the increased pressure difference between the upper and lower parts, the fixing plate 611 is sucked by the suction force of the fan assembly 3, causing the fixing plate 611 to move towards the air outlet 5. When the fixing plate 611 moves, it drives the central shaft 613 to move synchronously. Here, it should be noted that the rotational connection between the rotating shaft 614 and the central shaft 613 is set such that the rotating shaft 614 can only rotate circumferentially inside the central shaft 613 and cannot move axially. Therefore, the movement of the central shaft 613 causes the rotating shaft 614 to move synchronously. Furthermore, the rotating shaft 614 drives the insertion shaft 123 to perform insertion movement inside the insertion pipe 124. Through the settings of the clamping member 125 and the guiding groove 126, when the insertion shaft 123 moves, the insertion shaft 123 rotates, and the insertion shaft 123 drives the rotating shaft 614 to rotate. Thus, the rotating shaft 614 drives the fixing rod 7 and the brush 8 to move to clean the surface of the filter screen body 602. After the filter screen body 602 is cleaned, the filter screen body 602 can pass air again, and the pressure difference between the upper and lower parts returns to normal. Through the action of the support spring 14, the connecting shaft 122 rebounds towards the air inlet 4, causing the fixing plate 611 to reset. At the same time, the fixing rod 7 and the brush 8 also reset;

[0045] Embodiment 2

[0046] On the basis of Embodiment 1, a textile dust collection device for textile use is disclosed. As shown in Figure 1 , Figure 4 , Figure 5 it includes a torsion spring 16. When the rotating shaft 614 rotates as the insertion shaft 123 moves axially, the torsion spring 16 can store energy, so that only when the filter screen assembly 6 moves to the lower limit position, the torsion spring 16 releases, causing the rotating shaft 614 to drive the fixing rod 7 and the brush 8 to clean the filter screen body 602;

[0047] In Embodiment 1, since the blockage of the filter screen body 602 gradually worsens, the pressure difference between the upper and lower sides of the filter screen body 602 gradually increases. When the filter screen body 602 just starts to be blocked, the filter screen body 602 will be sucked and moved due to the pressure difference, causing the filter screen body 602 to move slightly towards the air outlet 5. At this time, the rotating shaft 614 rotates slightly synchronously, and then the fixing rod 7 moves slightly to clean the filter screen body 602 within a small range. However, the cleaning area of the filter screen body 602 by the brush bristles 8 is relatively small and cannot cover the entire filter screen body 602, affecting the cleaning effect of the filter screen body 602. If the angle of the fan-shaped filter screen body 602 is set to be smaller to match the relatively small displacement of the brush bristles 8, it means that the partitions between adjacent filter screen bodies 602 increase, reducing the effective filtration area on the fixing plate 611 and affecting the filtration efficiency. Therefore, by setting the torsion spring 16, after the filter screen body 602 is blocked and the blockage area gradually increases, the filter screen body 602 will also gradually move towards the air outlet 5 as the pressure difference increases. When the rotation angle of the rotating shaft 614 is greater than the angle of the fan-shaped filter screen body 602, the torsion spring 16 stores and releases energy, causing the fixing rod 7 to rotate. The fixing rod 7 drives the brush bristles 8 to comprehensively clean the fan-shaped filter screen body 602, improving the cleaning effect;

[0048] In order for the torsion spring 16 to store energy for the rotation of the rotating shaft 614, in this embodiment, as Figure 5As shown, the rotating shaft 614 is set to include an upper shaft 641 and a lower shaft 642, and the upper shaft 641 and the lower shaft 642 are concentrically arranged. Both the upper shaft 641 and the lower shaft 642 are rotatably connected to the central shaft 613. A support shaft 17 is fixedly arranged at one end of the lower shaft 642 facing the upper shaft 641, and the other end of the support shaft 17 is rotatably connected to the upper shaft 641. One end of the torsion spring 16 is fixedly connected to the upper shaft 641, and the other end of the torsion spring 16 is fixedly connected to the lower shaft 642. The torsion spring 16 is sleeved outside the support shaft 17, so that the upper shaft 641 and the lower shaft 642 are elastically connected through the torsion spring 16. In addition, a clamping component 18 is arranged at the upper shaft 641. The clamping component 18 is used for circumferentially locking the upper shaft 641. First, the upper shaft 641 is locked by the clamping component 18. When the filter screen body 602 is displaced, the plug shaft 123 will first drive the lower shaft 642 to rotate. The rotation of the lower shaft 642 will cause the torsion spring 16 to twist and store energy. And due to the limitation of the clamping component 18, the upper shaft 641 cannot rotate, so energy is stored. Then when the filter screen body 602 moves to the lower limit position, the clamping component 18 is released. Through the stored energy of the torsion spring 16, the upper shaft 641 can immediately rotate, so as to drive the fixing rod 7 and the brush 8 to clean the sector-shaped filter screen body 602. Here, it should be noted that the lower limit position is set as when the plug shaft 123 is inserted and moved and rotated inside the plug tube 124, and the rotation angle is greater than the angle of the sector-shaped filter screen body 602, the clamping component 18 is released;

[0049] As Figure 4 , Figure 5 ,, Figure 8 and Figure 9As shown, the snap - fit component 18 specifically includes a socket hole 181, a locking shaft 182, a control cavity 183, a connection hole 184, a locking socket 185, a locking plug shaft 186, a return spring 187, a pull rope 188, and a circumferential limit component 189. Among them, a socket hole 181 is opened above the inside of the upper shaft 641, and a locking shaft 182 is rotatably arranged inside the socket hole 181. The upper shaft 641 is rotatably sleeved outside the locking shaft 182 through the socket hole 181, and the locking shaft 182 can only rotate inside the socket hole 181 and cannot move axially. One end of the locking shaft 182 extends outside the upper shaft 641. A control cavity 183 is also opened inside the locking shaft 182. A locking socket 185 is opened on the inner wall of the socket hole 181, and a connection hole 184 is opened at a position corresponding to the outer wall of the locking shaft 182 for communicating the locking socket 185 and the control cavity 183. The connection between the locking socket 185 and the connection hole 184 has a smooth transition. A locking plug shaft 186 is slidably inserted inside the connection hole 184. One end of the locking plug shaft 186 is inserted inside the locking socket 185, and the other end extends into the control cavity 183. A return spring 187 is arranged at one end of the locking plug shaft 186 located inside the control cavity 183, and a guide tube 19 is arranged at one end of the return spring 187. The return spring 187 is used to bounce the locking plug shaft 186 towards the locking socket 185. One end of the guide tube 19 is fixedly connected to the inner wall of the control cavity 183. In addition, a pull rope 188 is fixedly arranged at one end of the locking plug shaft 186 located inside the control cavity 183, and the other end of the pull rope 188 passes through the guide tube 19 and extends outside the locking shaft 182 through the outer circumferential wall of the guide tube 19. The pull rope 188 is guided by a guide post 20 inside the guide tube 19. A circumferential limit component 189 is fixedly arranged at one end of the locking shaft 182 located outside the socket hole 181 to circumferentially limit the locking shaft 182.

[0050] The circumferential limit component 189 includes a circumferential limit rod 1891 and a limit sleeve 1892. The circumferential limit rod 1891 is square - shaped, and the inner hole of the limit sleeve 1892 is also square - shaped. The circumferential limit rod 1891 is slidably inserted inside the limit sleeve 1892. The limit sleeve 1892 is fixedly arranged at the air inlet 4 of the collection box 1 through a support rod 13. One end of the pull rope 188 located outside the locking shaft 182 is fixedly connected to the limit sleeve 1892, and the pull rope 188 is in a slack state.

[0051] Therefore, under normal conditions, the locking plug shaft 186 is inserted into the locking socket 185 by the rebound of the return spring 187. When the filter screen assembly 6 is displaced, the central shaft 613 drives the upper shaft 641 to displace, and the upper shaft 641 drives the locking shaft 182 to displace. Since the locking shaft 182 is fixedly connected to the circumferential limiting rod 1891, the circumferential limiting rod 1891 will displace with the upper shaft 641 and cannot rotate under the limitation of the limiting sleeve 1892. Through the cooperation of the locking plug shaft 186 and the locking socket 185, the upper shaft 641 cannot rotate following the lower shaft 642, thereby locking the upper shaft 641. As the upper shaft 641 moves, the pull rope 188 will gradually become taut, and then the pull rope 188 will pull the locking plug shaft 186 to separate the locking plug shaft 186 from the locking socket 185, thereby releasing the upper shaft 641. The upper shaft 641 will immediately rotate under the action of the torsion spring 16 to clean the filter screen body 602. It should be noted that when the filter screen body 602 moves to the lower limit, the pull rope 188 becomes taut and separates the locking plug shaft 186 from the locking socket 185. After the filter screen body 602 is cleaned, the filter screen body 602 is ventilated again, and the pressure difference becomes smaller. Through the action of the support spring 14, the filter screen body 602 is reset, and the insertion shaft 123 is reset and moves inside the insertion pipe 124, thereby causing the lower shaft 642 to reverse. When the lower shaft 642 reverses, the locking socket 185 of the upper shaft 641 is separated from the locking plug shaft 186 and cannot be limited. Therefore, the lower shaft 642 drives the upper shaft 641 to rotate, causing the fixed rod 7 to drive the brush hair 8 to clean the filter screen body 602 in the reverse direction again. When the upper shaft 641 is reset, the locking socket 185 will move to align with the locking plug shaft 186. At this time, the pull rope 188 is slack, and through the action of the return spring 187, the locking plug shaft 186 continues to be inserted into the locking socket 185 to limit the upper shaft 641.

[0052] The principle of the present invention is as follows: When the present invention performs air separation treatment on the textile dust generated by a textile machine, the fan assembly 3 is first started. The fan assembly 3 sucks external air from the air inlet and discharges it through the air outlet 5. When the external air enters through the air inlet, it will be filtered by the filter assembly 6, thereby separating the textile dust in the air from the air, so that the textile dust is intercepted on the surface of the filter assembly 6, and the separated air is discharged through the air outlet 5. When the filter body 602 is severely blocked, the filter body 602 cannot pass air. Due to the increased pressure difference between the upper and lower parts, the fixing plate 611 is sucked by the suction force of the fan assembly 3, causing the fixing plate 611 to move towards the air outlet 5. When the fixing plate 611 moves, it will drive the central shaft 613 to move synchronously. The movement of the central shaft 613 will cause the rotating shaft 614 to move synchronously. Furthermore, the rotating shaft 614 will drive the insertion shaft 123 to perform insertion movement inside the insertion pipe 124. Through the settings of the clamping member 125 and the guiding groove 126, when the insertion shaft 123 moves, the insertion shaft 123 rotates. The insertion shaft 123 drives the rotating shaft 614 to rotate. When the rotating shaft 614 rotates, first, the insertion shaft 123 drives the lower shaft 642 to rotate, and the rotation of the lower shaft 642 causes the torsion spring 16 to twist. And through the clamping assembly 18, the upper shaft is locked, thereby storing energy. After that, when the filter body 602 moves to the lower limit position, the clamping assembly 18 is released. Due to the energy stored in the torsion spring 16, the upper shaft 641 can immediately rotate, thereby driving the fixing rod 7 and the brush 8 to clean the fan-shaped filter body 602.
