Description
Technical Field
[0001] This invention belongs to the field of textile machinery technology, and in particular relates to an automatic yarn clearing structure for a spinning machine and its usage method. Background Technology
[0002] With the automation upgrade of the textile industry, the ring spinning machine, as the core equipment in yarn production, directly affects product quality through its operating efficiency and stability. During the spinning process, the spindle (or spindle itself) is a key component for yarn winding, and its surface accumulates yarn tails due to yarn breakage and doffing operations. If these tails are not cleaned in time, the friction between the spindle and the yarn will decrease, making the yarn prone to slippage during subsequent doffing, affecting the continuity and uniformity of spinning. Furthermore, the accumulated yarn tails may become entangled on other components, causing equipment malfunctions and even safety hazards.
[0003] Traditional manual cleaning methods require machine shutdown, are inefficient, rely heavily on operator experience, and are prone to incomplete cleaning or damage to the spindle surface, thus affecting yarn quality. While some automatic yarn cleaning devices have emerged, they still suffer from the following drawbacks: First, their complex structure requires multiple sensors to coordinate and control the feeding and cutting positions, resulting in high costs and maintenance difficulties. Furthermore, they have a high failure rate in the high-flying, high-humidity environment of textile workshops, making maintenance challenging. Second, the dust collection mechanism's filtration system is prone to clogging, and the negative pressure adsorption effect decays rapidly, requiring frequent manual intervention and cleaning, thus disrupting production continuity.
[0004] To address these issues, we provide an automatic yarn clearing structure for a spinning machine and its usage method. Summary of the Invention
[0005] The purpose of this invention is to provide an automatic yarn clearing structure for a spinning frame and its usage method. By cooperating with a yarn clearing mechanism and a self-cleaning mechanism, the invention solves the problems of complex structure, low yarn clearing efficiency, and high cost of existing automatic yarn clearing structures for spinning frames.
[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.
[0007] This invention relates to an automatic yarn clearing structure for a spinning frame, comprising a spinning frame body, a spindle disc on one side of the spinning frame body, and a spindle rod on one side of the spindle disc; a yarn clearing mechanism on one side of the spinning frame body, the yarn clearing mechanism including a guide rail bolted to one side of the spinning frame body, a support frame slidably connected to the guide rail, a support plate fixedly connected to one side of the support frame, a fixed box fixedly connected to one side of the support plate, a mounting frame disposed within the cavity of the fixed box, a dust collection cylinder fixedly connected to the inner side of the mounting frame, and a cutter fixedly connected to the surface of the dust collection cylinder; a self-cleaning mechanism on one side of the support plate, the self-cleaning mechanism including a filter box fixedly connected to one side of the support plate, a negative pressure fan fixedly connected to the top of the filter box, and a filter cylinder rotatably connected to the cavity of the filter box via a bearing seat.
[0008] The invention is further configured such that a pulley is fixedly connected to the inner side of the support frame, and grooves adapted to the pulleys are opened at the top and bottom of the guide rail. A toothed plate is fixedly connected to the front of the guide rail, and the length of the guide rail covers the distribution range of multiple spindles. The support frame is slidably connected to the grooves of the guide rail through the inner pulley. There are two sets of pulleys, three in each set, to ensure that the support frame moves smoothly along the axial direction of the guide rail, while reducing the frictional resistance of the support frame movement. The toothed plate on the front of the guide rail meshes with the gear set inside the support frame to drive the support frame to feed axially.
[0009] The invention is further configured such that the inner wall of the support frame is connected to a first rotating shaft via a bearing seat shaft, and a first gear and a second gear are fixedly connected sequentially from top to bottom on the surface of the first rotating shaft. A third gear meshes with the surface of the second gear, and a second rotating shaft is fixedly connected to the shaft center of the third gear. A fourth gear is fixedly connected to the surface of the second rotating shaft. The first gear and the third gear are small gears, and the second gear and the fourth gear are large gears. The small-amplitude rotation of the first gear can be amplified by the gear set to the large-amplitude rotation of the fourth gear, ensuring that the fourth gear moves one workstation distance for each revolution on the toothed plate, matching the spacing of the spindle disc.
[0010] The present invention is further configured such that a drive motor is fixedly connected to the bottom of the support frame, and a sector gear is fixedly connected to the surface of the output shaft of the drive motor. The sector gear only intermittently meshes with the adjacent first gear to realize the periodic axial feed of the support frame (the support frame moves one station for each revolution).
[0011] The present invention is further configured such that a first bevel gear is fixedly connected to the end of the output shaft of the drive motor, a second bevel gear meshes with the surface of the first bevel gear, a reciprocating lead screw is fixedly connected to the shaft center of the second bevel gear, a threaded sleeve is sleeved on the surface of the reciprocating lead screw, a drive wheel is fixedly connected to the surface of the threaded sleeve, the first bevel gear meshes with the second bevel gear, converting the horizontal rotation of the drive motor into the vertical rotation of the reciprocating lead screw, and the threaded sleeve is threadedly engaged with the reciprocating lead screw.
[0012] The invention is further configured such that a sliding hole is provided on one side of the mounting bracket, a sliding rod is slidably connected to the inner cavity of the sliding hole, a first spring is sleeved on the sliding rod, one end of the sliding rod is fixedly connected to the inner cavity of the fixed box, a driving block is fixedly connected to one side of the mounting bracket, the first spring is sleeved on the outer side of the sliding rod, one end abuts against the inner wall of the fixed box, and the other end abuts against the side of the mounting bracket, providing an outward rebound force for the mounting bracket.
[0013] The invention is further configured such that a servo motor is fixedly connected to the top of the filter box, a worm gear is fixedly connected to the output shaft of the servo motor, a worm wheel meshes with the surface of the worm gear, and the other end of the worm gear is fixedly connected to the power shaft of the negative pressure fan. The worm wheel and worm gear are a reduction mechanism that converts the high-speed rotation of the servo motor into the low-speed stable rotation of the filter cartridge.
[0014] The invention is further configured such that a baffle is fixedly connected to the inner cavity of the filter box, a conveying cylinder is fixedly connected to the inner cavity of the filter box, a conveying roller is rotatably connected to the inner cavity of the conveying cylinder via a bearing seat, a scraper is rotatably connected to the surface of the conveying cylinder, a second spring is fixedly connected to one side of the scraper, the other end of the second spring is fixedly connected to the surface of the conveying cylinder, a feeding groove is opened on the surface of the conveying cylinder, the bottom of the conveying cylinder extends through to the other side of the baffle, the bottom of the conveying cylinder is a through-type design, one end of the conveying roller extends through to the outside of the filter box and is fixedly connected to a fifth gear, a sixth gear meshes on the surface of the fifth gear, and the shaft of the sixth gear is fixedly connected to the surface of the filter cylinder. When the filter cylinder rotates under the drive of the worm gear, the fifth gear and the sixth gear, the scraper pushes the wire ends outside the filter holes to the feeding groove, and during the rotation of the conveying roller, the wire ends that enter the inner cavity of the conveying cylinder through the feeding groove are conveyed downward to the collection box, realizing the self-cleaning of the filter cylinder, ensuring that its filter holes are not blocked, so that the negative pressure fan always maintains a stable adsorption force, and avoiding the secondary flying of wire ends due to filtration failure.
[0015] The invention is further configured such that the air inlet of the negative pressure fan is connected to the top of the filter cartridge via a pipe and a universal joint; a collection box is provided inside the filter box; a control panel is provided on the front of the filter box; suction pipes are connected to both sides of the filter box and one side of each of the two dust collection cylinders; when the negative pressure fan is running, a negative pressure is formed inside the dust collection cylinder, which attracts the wire ends cut by the cutter to the dust collection cylinder inlet, and then transports them to the inner cavity of the filter box via the suction pipes; the collection box is installed at the bottom of the filter box via a pull-out structure, and can be removed for cleaning through the side door when full; the control panel integrates start / stop buttons for the drive motor and servo motor, as well as a speed adjustment knob; the end of the suction pipe is designed as a telescopic flexible hose to avoid operational interference.
[0016] A method for using an automatic yarn clearing structure for a spinning machine includes the following steps;
[0017] A: When the spinning bobbin is fully wound with yarn, the spindle plate falls, and the yarn will wrap around the spindle a certain number of times (as a starter). At this time, the fully wound spinning bobbin is pulled away, the yarn is broken, and a new empty bobbin is installed on the spindle. Then the spindle plate moves up, and with the high-speed rotation of the spindle, the yarn automatically winds onto the empty bobbin to start the next cycle of spinning production. After multiple doffing cycles, a layer of yarn will accumulate on the spindle. At this time, it needs to be cleaned to prevent the spindle from losing friction, which would cause the yarn to slip and not wind around during subsequent doffing, affecting spinning production.
[0018] B: Fix the guide rail to the side of the spinning machine body with mounting bolts. The guide rail is modularly designed, and several guide rails can be spliced together as needed to improve the applicability of the mechanism. Then, slide the inner pulley of the support frame through the sliding groove side of the top and bottom of the guide rail.
[0019] C: Start the drive motor and servo motor through the control panel. The output shaft of the servo motor drives the negative pressure fan through the worm gear. The output shaft of the drive motor drives the sector gear and the first bevel gear to rotate. During the rotation of the sector gear, its gap drives the first gear to rotate. The first gear drives the third gear to rotate through the first shaft and the second gear. The third gear drives the fourth gear to rotate through the second shaft (the first gear and the third gear are small gears, and the second gear and the fourth gear are large gears. The speed is increased by the gear set to increase the small rotation of the first gear to the large rotation of the fourth gear, ensuring that the fourth gear moves a distance of one station on the toothed plate in one cycle). The fourth gear drives the support frame to move axially one station through the toothed plate.
[0020] D: The first bevel gear drives the reciprocating screw to rotate through the second bevel gear. The reciprocating screw drives the drive wheel to rotate through the screw sleeve. The drive wheel drives the mounting frame to move outward through the drive block (the contact surface between the drive block and the drive wheel is divided into three sections: the first plane, the inclined plane, and the second plane. The first plane is the area where the drive wheel runs when the sector gear meshes with the first gear. The inclined plane and the second plane are the areas where the drive wheel runs when the sector gear separates from the first gear. The second plane ensures that the cutter stays in the area closest to the spindle for a period of time to ensure the cleaning effect of the thread end) so that the dust collection cylinder and the cutter are close to the spindle. The cutter cuts the thread end on the surface of the spindle. The dust collection cylinder, together with the negative pressure fan, picks up the cut thread end and transports it to the inner cavity of the filter box through the suction pipe. The slide bar limits the mounting frame, and the first spring provides the mounting frame with the rebound force to facilitate its reset.
[0021] E: The wire ends entering the inner cavity of the filter box are intercepted by the filter cylinder. At this time, the worm gear drives the conveyor roller to rotate through the worm wheel. The conveyor roller drives the filter cylinder to rotate through the fifth and sixth gears. Since the conveyor cylinder is in a fixed state, and the scraper connected to the surface is in close contact with the surface of the filter cylinder under the action of the second spring, together with the rotation of the filter screen, the wire ends on its surface are pushed into the inner cavity of the conveyor cylinder. At the same time, the rotation of the conveyor roller will transport the wire ends downward and make them fall into the inner cavity of the collection box, keeping the surface of the filter cylinder clean and ensuring the suction force generated by the negative pressure fan, thereby ensuring the cleaning effect. The collection box makes it easy to remove the wire ends.
[0022] F: For every revolution of the drive motor, the support frame completes one axial feed (one station), and the cutter and the dust collection cylinder complete one "switching and adsorption" action, cleaning the tail yarn of multiple spindles in sequence until the cleaning task of all spindles is completed. Throughout the process, the motor only needs to be started and stopped through the control panel, without the need for manual intervention to adjust the position or clean the filter system, thus achieving efficient and stable automated yarn cleaning operation.
[0023] The present invention has the following beneficial effects.
[0024] 1. This invention uses a single drive motor to simultaneously control the axial stepping movement of the yarn clearing mechanism and the radial cutting action of the cutter. The output shaft of the drive motor drives the sector gear to intermittently mesh with the first gear, and the speed-increasing gear set drives the fourth gear to move precisely one station along the tooth plate. Simultaneously, the bevel gear set drives the reciprocating screw, so that the cutter periodically approaches the spindle to cut the tail yarn. The dual-action linkage ensures efficient cleaning of each spindle position without manual intervention, thus improving production efficiency.
[0025] 2. This invention solves the problem of easy clogging of traditional filters by integrating a negative pressure fan, a rotating filter cylinder, and a scraper into a self-cleaning mechanism. The servo motor synchronously drives the negative pressure fan and the conveying roller through a worm gear, which in turn drives the filter cylinder to rotate through a gear set. The scraper, under the action of the second spring, adheres tightly to the surface of the filter cylinder, scraping the intercepted wire ends into the conveying cylinder, and then discharges them into the collection box by the spiral conveying roller. The adsorption force is kept stable throughout the process, avoiding secondary flying of wire ends.
[0026] 3. This invention requires only two motors to achieve the entire process of yarn clearing, dust collection, and self-cleaning, without the need for electronic sensors or complex control programs. It has strong anti-interference capabilities and low cost. The guide rail adopts a modular splicing structure, which can be flexibly adapted to different specifications of spinning machines, greatly improving versatility. The drive block is designed with a three-section contour (plane, inclined plane, and plane), which allows the cutter to pause briefly at the nearest spindle position to ensure thorough cutting of the thread end. The first spring provides reliable reset force, and the action is precise and reliable.
[0027] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0039] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.
[0040] Example 1
[0041] Please see Figures 1-9 This invention relates to an automatic yarn clearing structure for a spinning frame, comprising a spinning frame body 1, a spindle disc 2 on one side of the spinning frame body 1, and a spindle rod 3 on one side of the spindle disc 2; a yarn clearing mechanism on one side of the spinning frame body 1, the yarn clearing mechanism including a guide rail 4 bolted to one side of the spinning frame body 1, a support frame 5 slidably connected to the guide rail 4, a support plate 6 fixedly connected to one side of the support frame 5, a fixing box 7 fixedly connected to one side of the support plate 6, a mounting frame 8 disposed in the inner cavity of the fixing box 7, a dust collection cylinder 9 fixedly connected to the inner side of the mounting frame 8, and a cutter 10 fixedly connected to the surface of the dust collection cylinder 9; the inner side of the support frame 5 is fixedly connected to... The system includes a pulley 14, and guide rail 4 with grooves 15 at the top and bottom that are adapted to the pulley 14. A toothed plate 16 is fixedly connected to the front of the guide rail 4. A first rotating shaft 17 is connected to the inner wall of the support frame 5 through a bearing seat shaft. A first gear 18 and a second gear 19 are fixedly connected to the surface of the first rotating shaft 17 from top to bottom. A third gear 20 meshes with the surface of the second gear 19. A second rotating shaft 21 is fixedly connected to the center of the third gear 20. A fourth gear 22 is fixedly connected to the surface of the second rotating shaft 21. A drive motor 23 is fixedly connected to the bottom of the support frame 5. A sector gear 24 is fixedly connected to the surface of the output shaft of the drive motor 23.
[0042] Further details: The spinning frame body 1 is the main body of the spinning equipment. The spindle disc 2 is horizontally installed on the side of the spinning area of the spinning frame body 1 via a bearing seat and is coaxially fixedly connected to the spindle rod 3. The spindle rod 3 extends vertically and is used to install empty bobbins. Its top end contacts the spinning yarn, and its bottom end is connected to the main motor through a transmission mechanism to achieve high-speed rotation. The outer diameter of the spindle disc 2 is slightly larger than that of the spindle rod 3. Due to yarn entanglement, tail yarn easily accumulates on its circumference surface, requiring regular cleaning. The yarn clearing mechanism is installed on the side of the spinning area of the spinning frame body 1, on the same side as the spindle disc 2. The guide rail 4 is fixed to the frame of the spinning frame body 1 along the axial direction of the spindle disc 2 by bolts. The length of the guide rail 4 covers the distribution range of multiple spindle discs 2. The support frame 5 is slidably connected to the guide rail 4 via the inner pulley 14 and the sliding groove 15. Next, there are two sets of pulleys 14, with three in each set, to ensure that the support frame 5 moves smoothly along the guide rail 4 axially, while reducing the frictional resistance of the support frame 5. The toothed plate 16 on the front of the guide rail 4 meshes with the gear set inside the support frame 5, driving the support frame 5 to feed axially. The first gear 18 and the third gear 20 are small gears, and the second gear 19 and the fourth gear 22 are large gears. The small rotation of the first gear 18 can be amplified by the gear set to make the fourth gear 22 rotate significantly, ensuring that the fourth gear 22 moves one station distance for each revolution on the toothed plate 16, matching the spacing of the spindle 2. The sector gear 24 only meshes intermittently with the adjacent first gear 18 to realize the periodic axial feed of the support frame 5 (the support frame 5 moves one station for each revolution).
[0043] Example 2
[0044] Please see Figures 1-9 Based on embodiment 1, a first bevel gear 25 is fixedly connected to the end of the output shaft of the drive motor 23, a second bevel gear 26 meshes with the surface of the first bevel gear 25, a reciprocating lead screw 27 is fixedly connected to the shaft center of the second bevel gear 26, a threaded sleeve 28 is sleeved on the surface of the reciprocating lead screw 27, a drive wheel 29 is fixedly connected to the surface of the threaded sleeve 28, a sliding hole 30 is opened on one side of the mounting bracket 8, a sliding rod 31 is slidably connected to the inner cavity of the sliding hole 30, a first spring 32 is sleeved on the sliding rod 31, one end of the sliding rod 31 is fixedly connected to the inner cavity of the fixed box 7, and a drive block 33 is fixedly connected to one side of the mounting bracket 8.
[0045] Further details: The first bevel gear 25 meshes with the second bevel gear 26, converting the horizontal rotation of the drive motor 23 into the vertical rotation of the reciprocating lead screw 27. The threaded sleeve 28 is threaded into the reciprocating lead screw 27. The drive wheel 29 contacts the drive block 33. The contact surface between the drive block 33 and the drive wheel 29 is divided into three sections: a first plane, an inclined plane, and a second plane. The first plane is the operating area of the drive wheel 29 when the sector gear 24 meshes with the first gear 18. The inclined plane and the second plane are the operating areas of the drive wheel 29 when the sector gear 24 disengages from the first gear 18. The second plane ensures that the cutter 10 stays in the area closest to the spindle 2 for a period of time, ensuring the cleaning effect of the thread end. Specifically, when the sector gear 24 disengages from the first gear 18, the drive wheel 29... The inclined plane pushes the drive block 33, causing the mounting frame 8 to move outward (the cutter 10 approaches the spindle 2). When the sector gear 24 meshes with the first gear 18, the plane of the drive wheel 29 contacts the drive block 33. The mounting frame 8 resets under the action of the first spring 32 (the first spring 32 is sleeved on the outside of the slide rod 31, one end abuts against the inner wall of the fixed box 7, and the other end abuts against the side of the mounting frame 8, providing the outward rebound force of the mounting frame 8) (the cutter 10 moves away from the spindle 2), completing one "forward and backward" cycle, synchronized with the action of the cutter 10 cutting the wire end. The output shaft of the servo motor 34 is fixedly connected to the worm gear 35 through a coupling. The worm wheel 36 and the worm gear 35 are a reduction mechanism, which converts the high-speed rotation of the servo motor 34 into the low-speed stable rotation of the filter cartridge 13.
[0046] Example 3
[0047] Please see Figures 1-9Based on Embodiments 1 and 2, a self-cleaning mechanism is provided on one side of the support plate 6. The self-cleaning mechanism includes a filter box 11 fixedly connected to one side of the support plate 6, a negative pressure fan 12 fixedly connected to the top of the filter box 11, a filter cylinder 13 rotatably connected to the inner cavity of the filter box 11 via a bearing seat, a servo motor 34 fixedly connected to the top of the filter box 11, a worm gear 35 fixedly connected to the output shaft of the servo motor 34, a worm wheel 36 meshing on the surface of the worm gear 35, and the other end of the worm gear 35 fixedly connected to the power shaft of the negative pressure fan 12. A baffle 37 is fixedly connected to the inner cavity of the filter box 11, a conveying cylinder 38 is fixedly connected to the inner cavity of the filter box 11, a conveying roller 39 rotatably connected to the inner cavity of the conveying cylinder 38 via a bearing seat, and a scraper 40 rotatably connected to the surface of the conveying cylinder 38. A second spring 41 is fixedly connected to one side of the scraper 40, and the other end of the second spring 41 is fixedly connected to the surface of the conveying cylinder 38. A feed groove 42 is opened on the surface of the conveying cylinder 38. The bottom of the conveying cylinder 38 extends through to the other side of the baffle 37. The bottom of the conveying cylinder 38 is a through-type design. One end of the conveying roller 39 extends through to the outside of the filter box 11 and is fixedly connected to the fifth gear 43. The surface of the fifth gear 43 is meshed with the sixth gear 44. The shaft of the sixth gear 44 is fixedly connected to the surface of the filter cylinder 13. The air inlet of the negative pressure fan 12 is connected to the top of the filter cylinder 13 through a pipe and a universal joint. A collection box 45 is provided in the inner cavity of the filter box 11. A control panel 46 is provided on the front of the filter box 11. Suction pipes 47 are connected to both sides of the filter box 11 and one side of the two dust collection cylinders 9.
[0048] Further details: The filter box 11 is bolted to the side of the support plate 6, adjacent to the fixed box 7. The negative pressure fan 12 is fixed to the top of the filter box 11. The filter cylinder 13 is horizontally installed in the inner cavity of the filter box 11 via a bearing seat. Filter holes are evenly distributed on the circumferential surface of the filter cylinder 13 to intercept wire ends. The conveying cylinder 38 is coaxially fixed to the outside of the filter cylinder 13, with a clearance fit to the inner wall of the filter box 11. The scraper 40 is pressed against the surface of the filter cylinder 13 by the second spring 41. When the filter cylinder 13 rotates under the drive of the worm gear 36, the fifth gear 43, and the sixth gear 44, the scraper 40 pushes the wire ends outside the filter holes to the feed trough 42. During the rotation of the conveying roller 39, the wire ends will enter the feed trough 42. The wire ends inside the feed cylinder 38 are conveyed downwards to the collection box 45, achieving self-cleaning of the filter cylinder 13 and ensuring that its filter pores are not blocked. This ensures that the negative pressure fan 12 maintains a stable suction force and prevents the wire ends from flying again due to filtration failure. When the negative pressure fan 12 is running, a negative pressure is formed inside the dust collection cylinder 9, which attracts the wire ends cut by the cutter 10 to the inlet of the dust collection cylinder 9 and conveys them to the inner cavity of the filter box 11 through the suction pipe 47. The collection box 45 is installed at the bottom of the filter box 11 through a pull-out structure and can be removed for cleaning through the side door when full. The control panel 46 integrates the start / stop buttons and speed adjustment knobs of the drive motor 23 and servo motor 34. The end of the suction pipe 47 is designed as a telescopic flexible hose to avoid operational interference.
[0049] A method for using an automatic yarn clearing structure for a spinning machine includes the following steps;
[0050] A: When the spinning bobbin is fully wound with yarn, the spindle plate falls, and the yarn will wrap around a certain number of times at the spindle 2 (as a starter). At this time, the fully wound spinning bobbin is pulled away, the yarn is broken, and a new empty bobbin is installed on the spindle 3. Then the spindle plate moves up, and with the high-speed rotation of the spindle 3, the yarn automatically winds onto the empty bobbin to start the next cycle of spinning production. After multiple doffing cycles, a layer of yarn will accumulate on the spindle 2. At this time, it needs to be cleaned to prevent the spindle 2 from losing friction, which would cause the yarn to slip and not wind around during subsequent doffing, affecting spinning production.
[0051] B: Fix the guide rail 4 to the side of the spinning machine body 1 with mounting bolts. The guide rail 4 is modularly designed and several guide rails 4 can be spliced together as needed to improve the applicability of the mechanism. Then, slide the inner pulley 14 of the support frame 5 through the sliding groove 15 at the top and bottom of the guide rail 4.
[0052] C: Drive motor 23 and servo motor 34 are started via control panel 46. The output shaft of servo motor 34 drives negative pressure fan 12 through worm gear 35. The output shaft of drive motor 23 drives sector gear 24 and first bevel gear 25 to rotate. During the rotation of sector gear 24, its gap drives first gear 18 to rotate. First gear 18 drives third gear 20 to rotate through first rotating shaft 17 and second gear 19. Third gear 20 drives fourth gear 22 to rotate through second rotating shaft 21 (first gear 18 and third gear 20 are small gears, second gear 19 and fourth gear 22 are large gears. The speed is increased by the gear set, increasing the small rotation of first gear 18 to the large rotation of fourth gear 22, ensuring that the distance of fourth gear 22 on toothed plate 16 in one cycle is one station distance). Fourth gear 22 drives support frame 5 to move axially one station through toothed plate 16.
[0053] D: The first bevel gear 25 drives the reciprocating lead screw 27 to rotate via the second bevel gear 26. The reciprocating lead screw 27 drives the drive wheel 29 to rotate via the threaded sleeve 28. The drive wheel 29 rotates via the drive block 33 (the contact surface between the drive block 33 and the drive wheel 29 is divided into three sections: a first plane, an inclined plane, and a second plane. The first plane is the operating area of the drive wheel 29 when the sector gear 24 meshes with the first gear 18, and the inclined plane and the second plane are the operating areas of the drive wheel 29 when the sector gear 24 is separated from the first gear 18). The second plane ensures that the cutter 10 stays in the area closest to the spindle 2 for a period of time to ensure the cleaning effect of the thread ends. It drives the mounting bracket 8 to move outward, so that the vacuum cleaner 9 and the cutter 10 are close to the spindle 2. The cutter 10 cuts the thread ends on the surface of the spindle 2. The vacuum cleaner 9, together with the negative pressure fan 12, picks up the cut thread ends and transports them to the inner cavity of the filter box 11 through the suction pipe 47. The slide bar 31 limits the mounting bracket 8, and the first spring 32 provides a rebound force to the mounting bracket 8 to facilitate its reset.
[0054] E: The wire ends entering the inner cavity of the filter box 11 are intercepted by the filter cylinder 13. At this time, the worm 35 drives the conveyor roller 39 to rotate through the worm wheel 36. The conveyor roller 39 drives the filter cylinder 13 to rotate through the fifth gear 43 and the sixth gear 44. Since the conveyor cylinder 38 is in a fixed state, and the scraper 40 connected to the surface is in close contact with the surface of the filter cylinder 13 under the action of the second spring 41, the wire ends on the surface are pushed into the inner cavity of the conveyor cylinder 38 in conjunction with the rotation of the filter screen. At the same time, the rotation of the conveyor roller 39 will convey the wire ends downward and make them fall into the inner cavity of the collection box 45, keeping the surface of the filter cylinder 13 clean and ensuring the adsorption force generated by the negative pressure fan 12, thereby ensuring the cleaning effect. The collection box 45 is convenient for removing wire ends.
[0055] F: For every revolution of the drive motor 23, the support frame 5 completes one axial feed (one station), and the cutter 10 and the dust collection cylinder 9 complete one "switching and adsorption" action, cleaning the tail yarn of multiple spindles 2 in sequence until the cleaning task of all spindles 2 is completed. Throughout the process, the motor only needs to be started and stopped through the control panel 46, without the need for manual intervention to adjust the position or clean the filter system, thus achieving efficient and stable automated yarn cleaning operation.
[0056] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
