Specifically, an exhaust port 5 is opened at one end of the collection box 1, and the fan assembly 3 is connected to the exhaust port 5 through a flange; The other end of the collecting box 1 is provided with an air inlet 4, and the air inlet 4 and the air outlet 5 are interconnected, and a filter assembly 6 is provided at the air inlet 4, and then when the fan assembly 3 is turned on, the fan assembly 3 can inhale external air from the air inlet and discharge it through the air outlet 5, and the external air will be filtered through the filter assembly 6 after entering through the air inlet 4, and then the textile dust in the air will be separated from the air, so that the textile dust is intercepted on the surface of the filter assembly 6, and the separated air is discharged from the air outlet 5; Considering that after working for a long time, a large amount of textile dust will be retained on the surface of the filter assembly 6, and the textile dust will be entangled and accumulated to cover and block the filter holes, so that the air permeability of the filter assembly 6 is reduced, and then the filtering effect is reduced. Therefore, the filter assembly 6 needs to be cleaned in time; In order to clean the filter assembly 6, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the filter assembly 6 is specifically configured to include a fixed frame 601 and a filter body 602, the fixed frame 601 is arranged inside the collection box 1, the fixed frame 601 includes a fixed plate 611, a fan-shaped groove 612 and a central axis 613, wherein the fixed plate 611 is arranged inside the collection box 1, and a fan-shaped groove 612 is opened inside the fixed plate 611, and a plurality of fan-shaped grooves 612 are provided, and the plurality of fan-shaped grooves 612 are arranged in an annular array with the center position of the fixed plate 611 as the center of the circle, and a central axis 613 is also fixedly provided at the center position of the fixed plate 611, and a filter body 602 is fixedly provided inside each fan-shaped groove 612, and the filter body 602 is also arranged in a fan shape, and in this embodiment, four fan-shaped grooves 612 are provided; A rotating shaft 614 is coaxially arranged inside the central shaft 613, and both ends of the rotating shaft 614 extend to both ends of the central shaft 613 respectively. A fixing rod 7 is fixedly arranged on the outer wall of the outer circumference of one end of the rotating shaft 614 located in the direction of the air inlet 4, and there are multiple fixing rods 7, and the number of the fixing rods 7 is the same as the fan-shaped groove 612, so that one fixing rod 7 can correspond to one fan-shaped groove 612. In this embodiment, four fixing rods 7 are arranged, 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, and the four fixing rods 7 are fixedly arranged with bristles 8 facing the filter body 602, and there are a plurality of bristles 8, and the end of the bristles 8 facing the filter body 602 is in contact with the surface of the filter body 602; Therefore, when the filter body 602 needs to be cleaned, the rotating shaft 614 is rotated, and the rotation of the rotating shaft 614 drives the fixed rod 7 to rotate, so that each fixed rod 7 drives the bristles 8 to clean and transfer the textile dust such as flying catkins on the surface of the corresponding fan-shaped filter body 602, so that the textile dust covering the filter holes on the surface of the filter body 602 is scraped off, so that the filter body 602 is ventilated again. It should be noted that the textile dust on the surface of the filter body 602 is scraped off by the bristles 8. In other embodiments, the bristles 8 can also be set as a scraper, and the textile dust on the surface of the filter body 602 is scraped off by the scraper; In order to collect the textile dust after cleaning, and thus prevent the flying cotton wool after cleaning from continuing to fall on the surface of the filter body 602 and blocking the filter body 602 again, as shown in FIG. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a collecting groove 9 is provided at the partition between two adjacent fan-shaped grooves 612 on the fixed plate 611, and the collecting groove 9 runs through the upper and lower end surfaces of the fixed plate 611. In addition, a collecting bin 10 is fixedly provided at the partition between each adjacent fan-shaped groove 612, and the collecting bin 10 is provided on the fixed plate 611 toward the exhaust port 5, the interior of the collecting bin 10 is connected with the interior of the collecting groove 9, one end of the collecting bin 10 is fixedly connected with the central axis 613, and the end of the collecting bin 10 facing the inner wall of the collecting box 1 is set to be open, and a dust collecting port 11 is provided at the corresponding position of the box wall of the collecting box 1 and the opening, and the opening is connected with the dust collecting port 11. In addition, it should be noted that the fixing rod 7 is normally aligned parallel to the collecting groove 9, so that when the rotating shaft 614 rotates, the rotating shaft 614 is rotated by an angle so that the rotating shaft 614 rotates. The shaft 614 drives the fixed rod 7 to move from the mutually parallel collecting slots 9 to the next collecting slot 9. In the present embodiment, four fixed rods 7 are arranged in a circular array. Therefore, the rotation angle of the rotating shaft 614 is ninety degrees. Then, the rotating shaft 614 is rotated ninety degrees, so that the fixed rod 7 drives the bristles 8 to move to the next collecting slot 9. During the movement, the bristles 8 can clean the textile dust on the surface of the fan-shaped filter body 602 and transfer it to the inside of the collecting slot 9. Thus, the rotation of the rotating shaft 614 drives the fixed rod 7 and the bristles 8 to move to clean the textile dust on the surface of the filter body 602 and sweep the textile dust into the inside of the collecting slot 9. After that, the textile dust enters the inside of the collecting bin 10 from the collecting slot 9. The staff can regularly take out the textile dust inside the collecting bin 10 through the dust removal port 11. In order to improve the convenience of cleaning the filter body 602, the cleaning of the filter body 602 can be self-cleaning without the need for staff to start. The cleaning of the filter body 602 can be started according to its own blockage situation, such as Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the cross-sectional shape of the fixed frame 601 is the same as that of the collecting box 1, and the cross-sectional shapes of the fixed frame 601 and the collecting box 1 are both set to be square, and the four outer walls of the fixed plate 611 are respectively fitted and slidably matched with the four inner walls of the collecting box 1. In order to improve the sealing performance, sealing pads can be optionally provided on the four outer walls of the fixed plate 611 to improve the sliding sealing performance, so that the fixed frame 601 can slide in the inner cavity of the collecting box 1, and accordingly, the end of the collecting bin 10 facing the inner wall of the collecting box 1 is also fitted and slidably matched with the inner wall of the collecting box 1, and the filter assembly 6 is set to be movable in the inner cavity of the collecting box 1 through the fixed frame 601, so that after the filter body 602 is blocked and as the blockage worsens, the air permeability of the filter body 602 decreases, so that the upper and lower pressure differences become larger, and the suction force of the fan assembly 3 can suck the fixed frame 601 and move the fixed frame 601 toward the exhaust port 5; When the filter body 602 is blocked, 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 the displacement of the filter assembly 6 is converted into the rotation of the rotating shaft 614 by the conversion assembly 12; More specifically, Figure 4 , Figure 5 and Figure 7As shown, the conversion assembly 12 includes a limiting ring 121, a connecting shaft 122, a plug-in shaft 123, a plug-in tube 124, a clamp 125 and a guide groove 126, wherein the limiting ring 121 is arranged between the exhaust port 5 and the fixed plate 611, and a support rod 13 is fixedly arranged on the outer circumferential outer wall of the limiting ring 121, and a plurality of support rods 13 are arranged, and the other end of the support rod 13 is fixedly connected to the inner wall of the collection box 1, and the connecting shaft 122 is slidably plugged into the interior of the limiting ring 121, and positioning plates 15 are fixedly arranged at both ends of the connecting shaft 122, and the plugging of the connecting shaft 122 and the limiting ring 121 is limited by the positioning plates 15, and a support spring 14 is arranged between the two positioning plates 15, and the support spring 14 is sleeved on the outside of the connecting shaft 122, one end of the support spring 14 is against the positioning plate 15, and the other end is against the limiting ring 121, and then the connecting shaft 122 is directed toward the filter body 602 through the support spring 14. The limit ring 121 and the filter assembly 6 are also provided with a plug-in tube 124, and the plug-in tube 124 and the positioning plate 15 are both fixedly arranged inside the collection box 1 through the support rod 13, and the plug-in tube 124 is slidably plugged with a plug-in shaft 123 inside, and the outer wall of the plug-in shaft 123 fits with the inner wall of the plug-in tube 124, and one end of the plug-in shaft 123 is rotatably connected with the positioning plate 15 at one end of the connecting shaft 122 toward the filter assembly 6, and the plug-in shaft 123 is rotatably connected with the positioning plate 15 at one end of the connecting shaft 122. The connecting shaft 123 is arranged concentrically with the connecting shaft 122, and one end of the plug-in shaft 123 facing the filter assembly 6 is fixedly connected to one end of the rotating shaft 614 concentrically, and a clamp 125 is fixedly arranged on the outer wall of the outer circumference of one end of the plug-in shaft 123, and the clamp 125 is specifically a cylindrical shaft body, and a guide groove 126 is opened on the inner wall of the plug-in tube 124, and the guide groove 126 extends from one end of the plug-in tube 124 to the other end of the plug-in tube 124, and the guide groove 126 is in an inclined state; Specifically, one end of the guide groove 126 extends along the circumferential direction of the plug-in tube 124 and extends along the axis of the plug-in tube 124, and then extends to the opening of the other end of the plug-in tube 124, and the two ends of the guide groove 126 are staggered up and down, and the two ends of the guide groove 126 are at different positions on the circumferential line of the plug-in tube 124, and the clamping member 125 on the outer wall of the plug-in shaft 123 is movably plugged into the inside of the guide groove 126. When the plug-in shaft 123 is plugged and moved axially along the inside of the plug-in tube 124, the arrangement of the clamping member 125 and the guide groove 126 can make the plug-in shaft 123 rotate while moving axially, thereby realizing the conversion of the longitudinal movement of the filter assembly 6 into the rotation of the rotating shaft 614; Through the above arrangement, the displacement of the filter assembly 6 is limited by the cooperation of the connecting shaft 122 and the limiting ring 121, and the filter assembly 6 is reset by the setting of the supporting spring 14; Therefore, when a large area of ​​the filter body 602 is blocked, the filter body 602 cannot be ventilated. Due to the increase in the pressure difference between the upper and lower parts, the suction force of the fan assembly 3 sucks the fixed plate 611, so that the fixed plate 611 moves toward the exhaust port 5. When the fixed plate 611 moves, it will drive the central axis 613 to move synchronously. It should be noted that the rotation connection between the rotating shaft 614 and the central axis 613 is set so that the rotating shaft 614 can only rotate in a circle inside the central axis 613 and cannot move axially. Therefore, the movement of the central axis 613 will cause the rotating shaft 614 to move synchronously, and then the rotating shaft 614 will drive the plug-in shaft 123 is inserted and moved inside the plug-in tube 124. The arrangement of the clamp 125 and the guide groove 126 allows the plug-in shaft 123 to rotate when it moves, and the plug-in shaft 123 drives the rotating shaft 614 to rotate, so that the rotating shaft 614 drives the fixing rod 7 and the bristles 8 to move and clean the surface of the filter body 602. After the cleaning of the filter body 602 is completed, the filter body 602 is ventilated again, and the upper and lower pressure differences return to normal. The supporting spring 14 rebounds the connecting shaft 122 toward the air inlet 4, so that the fixing plate 611 is reset, and the fixing rod 7 and the bristles 8 are also reset at the same time. Example 2 Based on Example 1, a textile dust collecting device for textile use is disclosed, such as Figure 1 , Figure 4 , Figure 5 As shown, it includes a torsion spring 16, through which the torsion spring 16 can store force when the rotating shaft 614 rotates along with the axial movement of the plug-in shaft 123, so that only when the filter assembly 6 moves to the lower limit position, the torsion spring 16 is released, so that the rotating shaft 614 drives the fixing rod 7 and the bristles 8 to clean the filter body 602; In Example 1, since the blockage of the filter body 602 is gradually aggravated, the upper and lower pressure differences of the filter body 602 are gradually increased. When the filter body 602 is just blocked, the filter body 602 will be sucked due to the pressure difference, causing the filter body 602 to move slightly toward the exhaust port 5. At this time, the rotating shaft 614 simultaneously rotates slightly, so that the fixing rod 7 is slightly displaced to clean the filter body 602 in a small range. The cleaning area of ​​the filter body 602 by the bristles 8 is small and cannot cover the entire filter body 602, affecting the cleaning effect of the filter body 602. If the fan-shaped filter body 602 is rotated at an angle If a smaller displacement of the brush 8 is arranged to match a smaller displacement, it means that the number of partitions between two adjacent filter bodies 602 increases, which reduces the effective filtering area on the fixed plate 611 and affects the filtering efficiency. Therefore, by arranging the torsion spring 16, after the filter body 602 is blocked and the blocked area gradually increases, the filter body 602 will also gradually move toward the exhaust port 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 body 602, the torsion spring 16 is released to rotate the fixed rod 7, and the fixed rod 7 drives the brush 8 to comprehensively clean the fan-shaped filter body 602, thereby improving the cleaning effect. In order to store force for the rotation of the rotating shaft 614 in the torsion spring 16, in this embodiment, Figure 5As shown, the rotating shaft 614 is configured to include an upper shaft 641 and a lower shaft 642, and the upper shaft 641 and the lower shaft 642 are concentrically arranged, and the upper shaft 641 and the lower shaft 642 are both rotatably connected to the central shaft 613, and 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, and 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, and the torsion spring 16 is sleeved on the outside of the support shaft 17, and then the upper shaft 641 and the lower shaft 642 are elastically connected through the torsion spring 16, and in addition, a clamping assembly 18 is provided at the upper shaft 641, and the clamping assembly 18 is used to circumferentially lock the upper shaft 641, and the clamping assembly 18 is first The upper shaft 641 is locked first. When the filter body 602 is displaced, the plug-in shaft 123 will first drive the lower shaft 642 to rotate, and the rotation of the lower shaft 642 will cause the torsion spring 16 to twist to accumulate force, and due to the limit of the clamping assembly 18, the upper shaft 641 cannot rotate, thereby accumulating force. After that, when the filter body 602 moves to the lower limit, the clamping assembly 18 is released, and the upper shaft 641 can rotate immediately through the force accumulated by the torsion spring 16, thereby driving the fixing rod 7 and the bristles 8 to clean the fan-shaped filter body 602. It should be noted here that the lower limit is set to be when the plug-in shaft 123 is inserted, moved and rotated inside the plug-in tube 124, and the rotation angle is greater than the angle of the fan-shaped filter body 602, the clamping assembly 18 is released; like Figure 4 , Figure 5 ,, Figure 8 and Fig. 9As shown, the card assembly 18 specifically includes a plug hole 181, a locking shaft 182, a control chamber 183, a connecting hole 184, a locking plug hole 185, a locking plug shaft 186, a reset spring 187, a pull rope 188 and a circumferential limit assembly 189, wherein a plug hole 181 is opened at the top of the upper shaft 641, and a locking shaft 182 is rotatably arranged inside the plug hole 181, and the upper shaft 641 is rotatably sleeved on the outside of the locking shaft 182 through the plug hole 181, and the locking shaft 182 is only The locking shaft 182 can rotate inside the plug hole 181 but cannot move axially. One end of the locking shaft 182 extends to the outside of the upper shaft 641. A control cavity 183 is also provided inside the locking shaft 182. A locking plug hole 185 is provided on the inner wall of the plug hole 181. A connecting hole 184 is provided on the outer wall of the locking shaft 182 at a position corresponding to the locking plug hole 185, which is used to connect the locking plug hole 185 with the control cavity 183. The locking plug hole 185 and the connecting hole 184 have a smooth transition at the joint. A locking plug shaft 186 is slidably inserted into the interior of the control chamber 183, and one end of the locking plug shaft 186 is inserted into the locking socket 185, and the other end extends into the control chamber 183, and a return spring 187 is provided at one end of the locking plug shaft 186 located in the control chamber 183, and a guide tube 19 is provided at one end of the return spring 187, and the return spring 187 is used to rebound the locking plug shaft 186 toward the locking socket 185, and one end of the guide tube 19 is fixedly connected to the inner wall of the control chamber 183. In addition, a pull rope 188 is fixedly provided at one end of the locking plug shaft 186 located inside the control chamber 183, and the other end of the pull rope 188 passes through the guide tube 19 and the outer circumferential outer wall of the guide tube 19 to extend to the outside of the locking shaft 182. The pull rope 188 is guided by the guide column 20 inside the guide tube 19, and a circumferential limit assembly 189 is fixedly provided at one end of the locking shaft 182 located outside the plug hole 181, and the locking shaft 182 is circumferentially limited by the circumferential limit assembly 189. The circumferential limiting assembly 189 includes a circumferential limiting rod 1891 and a limiting sleeve 1892, and the circumferential limiting rod 1891 is set to be square, and the inner hole of the limiting sleeve 1892 is also set to be square, the circumferential limiting rod 1891 is slidably inserted in the limiting sleeve 1892, and the limiting sleeve 1892 is fixedly arranged at the air inlet 4 of the collection box 1 through the support rod 13, and the end of the pull rope 188 located outside the locking shaft 182 is fixedly connected to the limiting sleeve 1892, and the pull rope 188 is in a loose state; Therefore, under normal conditions, the locking plug shaft 186 is inserted into the locking plug hole 185 through the rebound of the return spring 187, and when the filter 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 limit rod 1891, the circumferential limit rod 1891 will displace with the upper shaft 641, and the circumferential limit rod 1891 will not be able to move under the limit of the limit sleeve 1892. The locking plug shaft 186 and the locking socket 185 cooperate to prevent the upper shaft 641 from rotating with the lower shaft 642, thereby locking the upper shaft 641. As the upper shaft 641 moves, the pull rope 188 gradually tightens, and then the pull rope 188 pulls the locking plug shaft 186, so that the locking plug shaft 186 is separated from the locking socket 185, thereby releasing the upper shaft 641. The upper shaft 641 will immediately rotate through the action of the torsion spring 16, thereby locking the filter screen. The main body 602 is cleaned, and it should be noted that when the filter body 602 moves to the lower limit, the pull rope 188 is tightened and the locking plug shaft 186 is separated from the locking plug hole 185. When the filter body 602 is cleaned, the filter body 602 is ventilated again, the pressure difference becomes smaller, and the filter body 602 is reset through the action of the support spring 14, and the plug shaft 123 is reset and moved inside the plug tube 124, thereby reversing the lower shaft 642. At this time, the lower shaft 642 is reversed. The locking socket 185 of the upper shaft 641 is separated from the locking plug shaft 186 and cannot be limited. Then the lower shaft 642 drives the upper shaft 641 to rotate so that the fixing rod 7 drives the bristles 8 to brush the filter body 602 in the opposite direction again. When the upper shaft 641 is reset, the locking socket 185 will move to be aligned with the locking plug shaft 186. At this time, the pull rope 188 is relaxed, and the locking plug shaft 186 continues to be inserted into the locking socket 185 through the action of the reset spring 187 to limit the upper shaft 641.

[0019] The principle of the present invention is as follows: when the present invention performs air separation processing on the textile dust generated by the textile machine, the fan assembly 3 is first started, and the fan assembly 3 sucks in the external air from the air inlet and discharges it through the exhaust port 5. After the external air enters from the air inlet, it will be filtered through the filter assembly 6, and then the textile dust in the air will be separated from the air, so that the textile dust is intercepted on the surface of the filter assembly 6, and the separated air is discharged from the exhaust port 5. When the filter body 602 is blocked in a large area, the filter body 602 cannot be ventilated. Due to the increase in the pressure difference between the upper and lower parts, the suction force of the fan assembly 3 will suck the fixed plate 611, so that the fixed plate 611 moves toward the exhaust port 5. When the fixed plate 611 moves, it will drive the central axis 613 to move synchronously. The movement of the central axis 613 will make The rotating shaft 614 moves synchronously, and then the rotating shaft 614 drives the plug-in shaft 123 to move in the plug-in tube 124. Through the arrangement of the clamp 125 and the guide groove 126, when the plug-in shaft 123 moves, the plug-in shaft 123 rotates, and the plug-in shaft 123 drives the rotating shaft 614 to rotate. When the rotating shaft 614 rotates, the plug-in shaft 123 first drives the lower shaft 642 to rotate, and the rotation of the lower shaft 642 causes the torsion spring 16 to twist, and the upper shaft is locked through the clamping assembly 18, thereby accumulating force. After that, when the filter body 602 moves to the lower limit position, the clamping assembly 18 is released, and the upper shaft 641 can rotate immediately through the accumulated force of the torsion spring 16, thereby driving the fixing rod 7 and the bristles 8 to clean the fan-shaped filter body 602.
