Technical Field
[0001] The invention relates to the technical field of textiles, in particular to a textile dust collecting device for a textile machine. Background Art
[0002] In the textile industry, fiber dust, yarn debris, and other dust particles generated during the operation of textile machines, if not collected promptly, will not only affect fabric quality but can also cause equipment failure and pollute the workshop environment. Traditional textile dust collection systems often use fan-driven negative pressure dust removal technology, requiring the fan and front-end filter components to be installed near the dust collection end. This results in bulky equipment and limited installation space. This is especially true for textile machines with precise layouts, where the large size increases installation difficulty, congests operating space, and hinders equipment maintenance. Furthermore, long-term exposure to high-dust environments can lead to a high risk of dust accumulation on the fan impeller, significantly increasing maintenance costs. Summary of the Invention
[0003] The object of the present invention is to provide a textile dust collecting device for a textile machine for textile use, so as to solve the problems raised in the above background technology.
[0004] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:
[0005] The present invention provides a textile dust collecting device for a textile machine, comprising a housing mounted above the textile machine, a rotating member rotatably disposed within the housing, and a textile dust exhaust pipe group and an air injection pipe group connected to the interior of the housing;
[0006] The shell is in the shape of an elongated strip as a whole, and the cross section of the shell includes a horizontal bottom edge, an inclined bottom edge and an arc top edge. The horizontal bottom edge, the inclined bottom edge and the arc top edge together form an arc-shaped cavity inside the shell. The inclined bottom edge of the shell is open so that the bottom of the shell forms a strip-shaped opening. The rotating component includes a rotating shaft coaxially mounted inside the cavity, and a flip plate fixed on the rotating shaft. The circumferential side of the flip plate is in sliding sealing cooperation with the inner wall of the cavity. The flip plate has a horizontal first terminal posture and a vertical second terminal posture. The flip plate can maintain the first terminal posture under the action of the reset element. The cavity on one side of the flip plate in the direction of rotation of the strip opening forms a dust suction channel, and the cavity on the other side of the flip plate forms an air jet channel.
[0007] The textile dust exhaust pipe group includes an exhaust pipe uniformly and vertically arranged on the top of the shell along the length direction of the shell, the bottom end of the exhaust pipe is connected to the mold cavity, the top end of the exhaust pipe is connected to the dust collection pipeline through a connecting flange, and the central axis of the exhaust pipe is in a vertical plane passing through one side of the central axis of the mold cavity; the jet pipe group is used to inject high-speed airflow into the jet channel, so that the flip plate rotates from the first posture to the second posture to complete the connection between the jet channel and the exhaust pipe.
[0008] Furthermore, the shell includes an arc top plate, a sealing plate horizontally welded on one side of the arc top plate in the arc direction, a first end plate welded at one end of the circular top plate in the length direction, and a second end plate detachably mounted at the other end of the circular top plate in the length direction. The sealing plate is provided with an arc sealing strip extending away from one side of the circular top plate to a position directly below the central axis of the circular top plate, and a sealing structure is provided between the arc sealing strip and the rotating shaft.
[0009] Furthermore, both ends of the rotating shaft respectively pass through the first end plate and the second end plate and are connected to a reset element, and the reset element includes a swing arm fixed to the end of the rotating shaft, and the end of the swing arm away from the rotating shaft is fixed with a counterweight by a bolt, when the flip plate is in the first terminal posture, the swing arm is in a vertical downward state; when the flip plate is in the second terminal posture, the swing arm is in a horizontal state.
[0010] Furthermore, with the center line of the rotating shaft as the dividing line, the two sides of the flip plate are respectively the first plate-shaped portion and the second plate-shaped portion. When the flip plate is in the first terminal posture, a guide assembly is provided on the top of the flip plate. The guide assembly includes a partition evenly and vertically arranged on the first plate-shaped portion along the length direction of the first plate-shaped portion, and a conical guide channel evenly separated on the second plate-shaped portion by a partition member, and the small mouth end of the conical guide channel corresponds to the bottom end of the exhaust pipe, and the outer edges of the partition and the partition member are both arc surfaces matching the inner circumferential surface of the cavity.
[0011] Furthermore, the jet pipe group includes a jet main pipe extending horizontally to just below the jet channel, and jet branch pipes evenly arranged on the top of the jet main pipe along the length direction of the jet main pipe, the top of the jet branch pipe is connected to the jet channel, and a first valve is provided on the jet main pipe.
[0012] Furthermore, when the jet channel is connected to the exhaust pipe, the dust suction channel is connected to the outside world through the strip-shaped dust suction port; a pressure relief assembly is provided between the first plate-shaped part and the jet channel, and the pressure relief assembly includes a cleaning pipe fixed to the outside of the first plate-shaped part, and the cleaning pipe is connected to the area between adjacent partitions through the jet pipe passing through the first plate-shaped part, and the middle part of the cleaning pipe is connected to the jet channel through a hose, and a second valve is provided on the hose, and the first valve and the second valve are interlocked and controlled.
[0013] Furthermore, a mounting base plate is detachably mounted on a side of the housing away from the strip-shaped opening, and mounting holes are evenly arranged on the mounting base plate.
[0014] Furthermore, the surface of the flip plate is covered with an antistatic coating, which is made of a composite of conductive polymer material and polytetrafluoroethylene, and has a surface resistivity of less than 10 9 Ω, and the coating thickness is 0.1-0.3mm.
[0015] Furthermore, a torque sensor is provided between the swing arm and the rotating shaft, and the torque sensor is electrically connected to the textile machine control system. When an abnormal fluctuation in the torque value of the swing arm is detected, an alarm signal is automatically triggered and the air supply pressure of the jet pipe group is adjusted.
[0016] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects:
[0017] 1. This invention eliminates the fan-driven design and instead utilizes the Bernoulli principle to create negative pressure within the exhaust duct, reducing the size of the core device and eliminating the need for front-end filtration components. This significantly saves installation space, making it suitable for narrow areas above textile machines and enhancing accessibility around the equipment. Furthermore, the elongated housing and exhaust ducts, evenly distributed along the length, precisely match the dust source across the width of the textile machine. By flexibly increasing or decreasing the housing length or the number of exhaust ducts, it can be quickly adapted to different machine models, demonstrating strong scalability.
[0018] 2. The high-speed airflow of the jet tube group of the present invention directly drives the flip plate to rotate, synchronously realizing channel switching and negative pressure dust collection without the need for additional valves. The power transmission and airflow drive are combined into one, which reduces energy consumption and prevents dust from escaping after shutdown, thus structurally ensuring the stability of the collection efficiency.
[0019] 3. The partition of the present invention divides the wide dust suction channel into narrow sub-channels, so that the dust in the width direction of the textile machine is evenly sucked into each exhaust pipe, solving the problem of insufficient suction in the edge area of the traditional single channel. The conical guide channel design reduces the air pressure requirement of the jet pipe group under the same dust suction volume, or extends the dust suction distance under the same air pressure, which is suitable for wide textile machines; when the flip plate is reset during shutdown, the partition scrapes the inner wall of the cavity to achieve integrated diversion and self-cleaning, thereby extending its maintenance cycle.
[0020] 4. The present invention adopts a counterweight block to replace the fatigue-prone spring, and uses pure mechanical gravity torque to achieve the reset of the flip plate, completely eliminating the problems of dust blockage and elastic attenuation, and improving the reset reliability in high-frequency vibration and temperature and humidity fluctuation environments.
[0021] 5. The pressure relief assembly of the present invention uses the residual airflow in the jet channel to sweep the dust at the bottom of the sub-channel, and cooperates with the partition to scrape the inner wall of the cavity when the flip plate is reset, thereby realizing the integration of airflow sweeping and mechanical cleaning, reducing the amount of dust retention and extending the maintenance cycle.
[0022] 6. The conductive polymer / polytetrafluoroethylene composite coating on the surface of the flip plate of the present invention effectively dissipates static electricity, avoids the risk of dust adsorption and static sparks, and is suitable for flammable and explosive textile scenarios. In addition, the torque sensor of the present invention collects rotational torque in real time and dynamically adjusts the air supply pressure, which can provide early warning of abnormalities such as dust blockage and sealing failure, thereby reducing the failure rate of the flip plate stuck.

DETAILED DESCRIPTION
[0036] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0037] See also Figures 1-9 The present invention provides a textile dust collecting device for a textile machine, comprising a housing 1 mounted above the textile machine, a rotating member 2 (such as a Figure 2 As shown), and a textile dust exhaust pipe group 3 and an air injection pipe group 4 communicated with the interior of the housing 1;
[0038] like Figure 1-Figure 3 As shown, the shell 1 is in the shape of an elongated strip, and the cross section of the shell 1 includes a horizontal bottom edge 141, an inclined bottom edge 121 and an arc top edge 131. The horizontal bottom edge 141, the inclined bottom edge 121 and the arc top edge 131 together form an arc-shaped cavity 11 (such as Figure 9 As shown in FIG, the inclined bottom edge 121 of the housing 1 is openly provided so that a strip-shaped opening 12 is formed at the bottom of the housing 1. The rotating member 2 includes a rotating shaft 21 coaxially mounted on the interior of the cavity 11, and a flip plate 22 fixed on the rotating shaft 21. The peripheral side of the flip plate 22 is in sliding sealing cooperation with the inner wall of the cavity 11. The flip plate 22 has a horizontal first terminal posture (as shown in FIG2 ) and a vertical second terminal posture (as shown in FIG2 ). Figure 7As shown), the flip plate 22 can maintain the first terminal posture under the action of the reset element 5, the cavity 11 on one side of the flip plate 22 rotating toward the strip opening 12 forms a dust suction channel 111, and the cavity 11 on the other side of the flip plate 22 forms an air injection channel 112;
[0039] like Figure 1 、 Figure 2 and Figure 7 As shown, the textile dust exhaust pipe group 3 includes an exhaust pipe 31 uniformly and vertically arranged on the top of the shell 1 along the length direction of the shell 1, the bottom end of the exhaust pipe 31 is connected to the cavity 11, and the top end of the exhaust pipe 31 is connected to the dust collection pipeline through a connecting flange 32, and the central axis of the exhaust pipe 31 is in a vertical plane passing through one side of the central axis of the cavity 11; the jet pipe group 4 is used to inject high-speed airflow into the jet channel 112, so that the flip plate 22 rotates from the first posture to the second posture to complete the connection between the jet channel 112 and the exhaust pipe 31.
[0040] This embodiment is based on the above-mentioned setting: Figure 2 As shown, when the jet tube assembly 4 is not started, the flip plate 22 is in a horizontal first terminal posture under the action of the reset element 5. At this time, the flip plate 22 is blocked between the strip opening 12 and the exhaust pipe 31. The dust suction channel 111 has a semicircular cross-section and is located above the jet channel 112. The jet channel 112 is slit-shaped. When the dust removal program is started, the high-speed airflow of the jet tube assembly 4 enters the jet channel 112 to increase the internal air pressure, and pushes the flip plate 22 to rotate around the rotation axis 21 to the vertical second terminal posture (reference Figure 7 As shown), at this time, the volume of the jet channel 112 increases and the volume of the dust suction channel 111 remains unchanged. As the flip plate 22 continues to rotate, when the jet channel 112 is connected with the exhaust pipe 31, the volume of the dust suction channel 111 becomes smaller (the bottom end of the dust suction channel 111 is connected with the outside through the strip opening 12, and the top end of the dust suction channel 111 is connected with the exhaust pipe 31). When the jet channel 112 is connected with the exhaust pipe 31, the gas in the jet channel 112 enters the exhaust pipe 31 and flows rapidly. The Bernoulli principle is used to form a negative pressure at the connection between the exhaust pipe 31 and the cavity 11, and then the external air carries the textile dust through the strip opening 12 and the dust suction channel 111 into the exhaust pipe 31, and the textile dust enters the filter assembly together with the high-speed airflow to complete the collection; when the machine is shut down, the jet pipe group 4 stops supplying air, and the flip plate 22 returns to the first posture under the action of the reset element 5, and is re-sealed to form a blockage to prevent the textile dust from escaping.
[0041] Compared with the traditional fan negative pressure dust removal system, the above design needs to be close to the dust collection end to ensure that the suction force can meet the dust collection requirements, and a filter component needs to be set at the front end of the fan (to eliminate the risk of dust accumulation on the fan impeller), resulting in a bloated equipment volume and limited installation space. Especially in equipment with precise layout such as textile machines, excessive volume will increase the difficulty of installation, occupy the operating space and affect equipment maintenance. The present invention uses the Bernoulli principle to provide the exhaust pipe 31 with the premise of meeting the dust collection requirements (under appropriate negative pressure), greatly reducing the volume of the core device, making the overall structure compact and light, saving equipment installation space and improving the convenience of operation around the textile machine, and reducing the restrictions of the equipment layout on the site. At the same time, it avoids the maintenance difficulties caused by dust accumulation of traditional fans, and has both high efficiency and practicality.
[0042] In addition, the design realizes automatic control of dust collection and blocking through the dynamic posture switching of the flip plate 22 without the need for additional valves. That is, the high-speed airflow of the jet pipe 72 drives the flip plate 22 to rotate and switch channels, while directly generating negative pressure dust collection through the flow rate difference, combining power transmission and airflow drive into one, simplifying the power system architecture and reducing energy consumption; at the same time, it avoids dust escape after shutdown, and structurally ensures the stability of the collection efficiency; and in addition, the layout of the long strip shell 1 and the exhaust pipe 31 evenly distributed along the length direction is also precisely adapted to the dust source distribution characteristics in the width direction of the textile machine. It can be adapted to different models by flexibly increasing the length of the shell 1 or the number of exhaust pipes 31, significantly enhancing the versatility and expansion capability of the device, ensuring efficient and stable collection of textile dust, and providing full-process guarantee for the clean operation of the textile machine.
[0043] like Figure 2 and Figure 6 As shown, in this embodiment, the shell 1 includes an arc top plate 13, a sealing plate 14 horizontally welded on one side of the arc direction of the arc top plate 13, a first end plate 15 welded at one end of the length direction of the circular top plate, and a second end plate 16 detachably installed at the other end of the length direction of the circular top plate. The sealing plate 14 extends away from one side of the arc top plate 13 to a position directly below the central axis of the arc top plate 13, and a sealing structure 18 is provided between the arc sealing strip 17 and the rotating shaft 21.
[0044] Based on the above-mentioned arrangement, the arc top plate 13, the sealing plate 14 and the first end plate 15 are welded to form an integrated main structure, and the second end plate 16 is detachably connected to the other end of the main structure to form a closed cavity (cavity 11) in the length direction of the shell 1, which is convenient for assembling the rotating component 2 during installation; and the circumferential side of the flip plate 22 is tightly attached to the arc top plate 13, the sealing plate 14, the first end plate 15 and the second end plate 16, and the design of the arc sealing strip 17 and the sealing structure 18 of the rotating shaft 21 can construct a dynamic sealing interface during the rotation of the flip plate 22 to ensure the sealed isolation of the dust suction channel 111 and the jet channel 112. For example, the lip sealing ring and the sealing structure 18 can be made of elastic silicone material, and small deformations are compensated by flexible sealing to ensure sealing.
[0045] like Figure 1 He Ru Figure 6 As shown, in this embodiment, both ends of the rotating shaft 21 pass through the first end plate 15 and the second end plate 16 respectively and are connected to the reset element 5. The reset element 5 includes a swing arm 51 fixed to the end of the rotating shaft 21. The end of the swing arm 51 away from the rotating shaft 21 is fixed with a counterweight 52 by a bolt. When the flip plate 22 is in the first terminal posture, the swing arm 51 is in a vertical downward state (refer to Figure 1 When the flip plate 22 is in the second terminal posture, the swing arm 51 is in a horizontal state (reference Figure 4 shown).
[0046] Based on the above configuration, when the flip plate 22 is in the first terminal position (horizontally blocked), the swing arm 51 points vertically downward (directly below the rotating shaft 21), and the vertical distance between the center of gravity of the counterweight 52 and the center of the rotating shaft 21 reaches a minimum. At this point, the gravitational torque is zero, and the system is in an initial equilibrium state. After the jet tube assembly 4 is activated, the high-speed airflow pushes the flip plate 22 to rotate counterclockwise, and the swing arm 51 rotates synchronously with the rotating shaft 21. When the flip plate 22 reaches the second terminal position, the swing arm 51 extends horizontally to one side of the rotating shaft 21, and the horizontal distance between the center of gravity of the counterweight 52 and the center of the rotating shaft 21 reaches a maximum value, forming a clockwise gravitational torque. When the jet tube assembly 4 stops supplying air, the air pressure in the jet channel 112 drops sharply, and the clockwise gravitational torque becomes the dominant force, driving the rotating shaft 21 to rotate in the opposite direction, causing the flip plate 22 to return to the first position. During this process, the swing arm 51 gradually falls back from the horizontal position to the vertical position, ensuring a smooth and impact-free reset process.
[0047] The present invention replaces fatigue-prone components such as springs and torsion springs, utilizing purely mechanical gravity reset. This eliminates reset failures caused by dust clogging the spring gap and elasticity attenuation. Furthermore, the gravitational properties of the counterweight 52 remain unaffected by the high-frequency vibrations and temperature and humidity fluctuations of textile machines, providing a constant reset torque and ensuring operational stability (whereas springs may experience temperature fluctuations leading to spring coefficient drift).
[0048] Furthermore, in view of the harsh environment of high dust and high fiber content in the textile workshop, the counterweight 52 can be made of stainless steel or sprayed with Teflon on the surface to improve its corrosion resistance; and a dust cover (not shown) can be provided at the bolted connection part between the swing arm 51 and the rotating shaft 21 to prevent the fiber entanglement from affecting the rotation.
[0049] like Figure 2 、 Figure 7 and Figure 9 As shown, in this embodiment, the center line of the rotating shaft 21 is used as the dividing line. Figure 9 As shown, the two sides of the flip plate 22 are respectively the first plate-shaped portion 221 and the second plate-shaped portion 222. When the flip plate 22 is in the first terminal posture, a guide component 6 is provided on the top of the flip plate 22. The guide component 6 includes a partition 61 uniformly and vertically arranged on the first plate-shaped portion 221 along the length direction of the first plate-shaped portion 221, and a conical guide channel 63 uniformly separated on the second plate-shaped portion by a partition member 62, and the small mouth end of the conical guide channel 63 corresponds to the bottom end of the exhaust pipe 31, and the outer edges of the partition 61 and the partition member 62 are both arc surfaces matching the inner circumferential surface of the cavity 11.
[0050] Based on the above arrangement, a partition 61 is evenly and vertically arranged on the first plate-shaped portion 221 along the length direction, dividing the dust collection channel 111 into a number of equally spaced independent sub-channels along the length direction of the shell 1. The cross section of each sub-channel is formed by the partition 61, the arc top plate 13, and the inner wall of the first plate-shaped portion 221. When the dust-laden airflow enters the dust collection channel 111 through the strip-shaped opening 12, the partition 61 forces the airflow to be evenly distributed to each sub-channel, avoiding a local low-pressure area caused by excessive flow on one side, and reducing the deviation of the dust collection amount per unit length (reference Figure 5 (as shown); the second plate-shaped portion 222 is evenly divided into tapered flow channels 63 by a partition member 62. The larger end of the channel faces the independent sub-channel, while the smaller end corresponds to the bottom end of the exhaust pipe 31. This tapered shape reduces airflow diffusion losses and improves energy utilization. Both the partition plates 61 and the partition member 62 have arcuate surfaces that closely contact the inner wall of the cavity 11, preventing airflow from flowing between the sub-channels.
[0051] In terms of dust collection efficiency, the partition 61 of the present invention divides the wide dust collection channel 111 into narrow sub-channels, so that the dust in the width direction of the textile machine is evenly sucked into each exhaust pipe 31, solving the problem of insufficient suction in the edge area of the traditional single channel. The design of the conical guide channel 63 reduces the air pressure requirement of the jet pipe group 4 under the same dust collection amount, or extends the dust collection distance under the same air pressure, which is suitable for wide textile machines; when the flip plate 22 is reset during shutdown, the partition 61 scrapes the inner wall of the cavity 11, realizing the integration of diversion and self-cleaning, and extending its maintenance cycle.
[0052] Furthermore, in order to improve structural reliability and sealing, the partition 61 is welded and fixed to the flip plate 22 using a stainless steel plate with a thickness of 3-5 mm and a yield strength of ≥205 MPa, thereby enhancing its overall rigidity and deformation deflection to prevent the partition 61 from bending due to airflow impact.
[0053] like Figure 5 As shown, in this embodiment, the jet pipe group 4 includes a jet main pipe 41 extending horizontally to just below the jet channel 112, and jet branch pipes 42 evenly arranged at the top of the jet main pipe 41 along the length direction of the jet main pipe 41. The top end of the jet branch pipe 42 is connected to the jet channel 112, and a first valve 43 is provided on the jet main pipe 41.
[0054] Based on the above-mentioned setting, the external air source (such as the compressed air output by the air compressor) is collected through the jet main pipe 41 extending horizontally to the bottom of the jet channel 112. After the pressure is stabilized in the main pipe, the high-speed airflow is vertically injected into the bottom of the jet channel 112 by the jet branch pipes 42 evenly arranged along its length. When the first valve 43 is opened, the compressed air is diverted to each branch pipe through the main pipe, and synchronously impacts the second plate-shaped portion 222 of the flip plate 22 with equal pressure, forming a uniform thrust torque, driving the flip plate 22 to rotate at a uniform speed around the rotating shaft 21, avoiding uneven force on one side of the flip plate 22 caused by single-point air supply; when the dust removal program is completed, the first valve 43 is closed to cut off the air source, the air pressure in the jet channel 112 drops sharply, and under the action of the gravity torque of the counterweight block 52, the flip plate 22 quickly returns to the first posture.
[0055] like Figure 8 As shown, in this embodiment, when the jet channel 112 is connected to the exhaust pipe 31, the dust suction channel 111 is connected to the outside through the strip dust suction port; a pressure relief component 7 is provided between the first plate-shaped portion 221 and the jet channel 112, and the pressure relief component 7 includes a cleaning pipe 71 fixed to the outside of the first plate-shaped portion 221, and the cleaning pipe 71 is connected to the area between the adjacent partitions 61 through the jet pipe 72 passing through the first plate-shaped portion 221, and the middle part of the cleaning pipe 71 is connected to the jet channel 112 through a hose 74, and a second valve 73 is provided on the hose 74, and the first valve 43 and the second valve 73 are interlocked and controlled.
[0056] Based on the above configuration, the design of the pressure relief assembly 7 cleverly utilizes the residual airflow of the jet channel 112 to achieve self-cleaning of the dust collection channel 111. Its working logic can be divided into two stages:
[0057] Dust removal phase (first valve 43 open): When the jet pipe assembly 4 injects high-speed airflow into the jet channel 112 through the first valve 43, the flip plate 22 rotates to the second position, connecting the jet channel 112 with the exhaust pipe 31 to achieve negative pressure dust collection. At this point, the second valve 73 is closed, isolating the cleaning pipe 71 from the jet channel 112, preventing the high-pressure airflow from interfering with the dust collection process. The dust-laden airflow within the dust collection channel 111 is drawn in through the strip opening 12 and evenly enters each exhaust pipe 31 through the sub-channels divided by the partition 61, completing dust collection.
[0058] Pressure relief cleaning stage (the first valve 43 is closed): After the dust removal program is completed, the first valve 43 is closed to cut off the air supply, and the flip plate 22 begins to reset under the action of the counterweight 52. At this time, the second valve 73 opens automatically, and the residual high-pressure airflow that has not yet completely dissipated in the jet channel 112 is introduced into the cleaning pipe 71 through the hose 74. The cleaning pipe 71 is arranged along the length direction of the first plate-shaped portion 221. The side close to the flip plate 22 is provided with a jet pipe 72 that passes through the first plate-shaped portion 221, and the outlet of the jet pipe 72 is precisely aligned with the gap between the adjacent partitions 61 (i.e., the bottom of the sub-channel). High-speed airflow is ejected from the jet pipe 72 to form a sweeping force, blowing the residual dust (such as fiber lint, yarn debris) accumulated between the adjacent partitions 61 into the conical channel to avoid dust retention and clogging the sub-channel, thereby extending the maintenance cycle.
[0059] In this embodiment, a mounting base plate 19 is detachably mounted on the side of the housing 1 away from the strip-shaped opening 12. The mounting base plate 19 is evenly distributed with mounting holes 191. When the collection device is to be integrated into a textile machine, the base plate is fastened to a frame crossbeam (or a custom bracket) at the top of the textile machine through the mounting holes 191.
[0060] In this embodiment, the surface of the flip plate 22 is covered with an antistatic coating, which is made of a conductive polymer material and polytetrafluoroethylene, and has a surface resistivity of less than 10 9 Ω, and the coating thickness is 0.1-0.3mm. The composite coating is made of polytetrafluoroethylene as the matrix material, providing an extremely low surface friction coefficient, making it difficult for dust particles to adhere. When the flip plate 22 rubs against the high-speed airflow and dust particles to generate static electricity, the surface charge can be quickly conducted to the housing 1 (housing 1 is grounded) through the coating. The surface resistivity of the coating is controlled at 10 9 Below Ω·cm, it can avoid static electricity accumulation causing dust adsorption and prevent static electricity sparks from igniting combustible dust, which is suitable for the environment of textile workshops.
[0061] In this embodiment, a torque sensor (not shown) is provided between the swing arm 51 and the rotating shaft 21. The torque sensor is electrically connected to the textile machine control system. When abnormal fluctuations in the torque value of the swing arm 51 are detected, an alarm signal is automatically triggered and the air supply pressure of the air jet assembly 4 is adjusted. A high-precision strain gauge torque sensor is provided at the connection between the swing arm 51 and the rotating shaft 21. Its detection end is connected to the swing arm 51, and its signal end is connected to the textile machine control system via a shielded cable. This torque sensor collects the torque signal of the swing arm 51 in real time. When dust blockage or seal failure causes the torque peak to exceed the limit but does not persist, the air supply pressure is automatically increased to maintain the rotational angular velocity of the flip plate 22. If the torque still does not meet the standard after adjustment, a mechanical failure is determined, and a shutdown command is issued to lock the air jet assembly 4 to prevent structural damage.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
