Abstract

This invention discloses a yarn feeding device for a spinning machine with traction function, belonging to the technical field of yarn feeding devices. It includes a main body with a fixed frame at its top, a yarn roller at its top, a shaped cam inside the yarn roller, and a movable linkage mechanism at its top. The movable linkage mechanism includes a roller, a movable frame, a first spring, an L-shaped rod, a limiting rod, a second spring, a rotating rod, a first connecting rod, and a second connecting rod. This invention guides multi-headed yarns through a guide wheel and a flow wheel, sequentially feeding them into the cavity of the adjusting mechanism.

When yarn fibers entangle the yarn roller, the resistance increases, achieving dynamic tension balance, improving cleaning efficiency, and preventing fiber entanglement.

Description

Technical Field

[0001] This invention relates to the field of yarn feeding device technology, specifically to a yarn feeding device for a spinning machine with traction function. Background Technology

[0002] The yarn feeding device for spinning machines is a key component in the textile machinery field. It is primarily used to stably and evenly transport yarn from yarn bobbins or yarn frames to the spinning mechanism to meet the needs of subsequent spinning processes. In traditional textile production, the design of the yarn feeding device directly affects yarn tension control, yarn feeding speed, and yarn quality. Early yarn feeding devices mostly adopted mechanical structures, such as gear transmission or friction wheel drive, achieving yarn traction and transport through mechanical contact. With the development of textile technology, modern yarn feeding devices have gradually incorporated electronic control technology. Sensors monitor yarn tension, and servo motors or stepper motors are used to precisely adjust the yarn feeding speed, thus adapting to different yarn materials and process requirements. Furthermore, the structural design of yarn feeding devices has become increasingly lightweight and modular, facilitating maintenance and adjustment. Some high-end models are also equipped with automatic detection functions, providing real-time feedback on yarn status to ensure the continuity and stability of the yarn feeding process. The application range of yarn feeding devices is wide, covering various spinning methods such as ring spinning, air-jet spinning, and vortex spinning. Optimizing their performance is of great significance for improving spinning efficiency and reducing energy consumption.

[0003] Existing yarn feeding devices for spinning machines with traction functions generally have the following drawbacks: First, in terms of tension control, traditional yarn feeding devices use mechanical fixed speed or simple spring pressure rod adjustment. Their rigid structure is difficult to dynamically adapt to the changes in yarn tension during operation, resulting in tension fluctuations forming a wavy surface. In the winding response stage, existing equipment relies on manual inspection to detect and handle winding faults, resulting in a significant time lag from detection to shutdown. In the fiber cleaning system, the fixed brushes or scrapers are structurally limited and cannot effectively clean the inside of the roller groove, causing the problem of fiber residue to persist. In addition, the existing dust removal devices in the workshop are only equipped with simple filter structures, generating a large amount of airborne particles during fiber stripping, which seriously affects the cleanliness of the production environment. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a yarn feeding device for a spinning machine with traction function, so as to solve the technical problems of traditional yarn feeding devices that use mechanical adjustment, which makes it difficult to dynamically adapt to changes in yarn tension, resulting in tension fluctuations, entanglement failures that rely on manual handling, delayed response, inability of fixed cleaning tools to thoroughly clean the roller grooves, serious fiber residue, insufficient filtration of the suction dust removal device, and fiber scattering that affects the workshop environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a yarn feeding device for a spinning machine with traction function, comprising a main body, a fixed frame at the top of the main body, a yarn roller at the top of the fixed frame, a shaped cam inside the yarn roller, and a movable linkage mechanism at the top of the fixed frame. The movable linkage mechanism includes a roller, a movable frame, a first spring, an L-shaped rod, a limiting rod, a second spring, a rotating rod, a first connecting rod, and a second connecting rod. The roller is disposed inside the movable frame and cooperates with the shaped cam. The movable frame is disposed on one side of the L-shaped rod. The first spring is disposed at one end of the L-shaped rod. The L-shaped rod is disposed on one side of the limiting rod, and the limiting rod is connected to the top of the fixed frame. The second spring is disposed inside the L-shaped rod. The rotating rod is disposed inside the L-shaped rod. The first connecting rod is disposed at the other end of the rotating rod, and the second connecting rod is connected to the top of the fixed frame.

[0006] By adopting the above technical solution, after the main body is connected to the power supply, the operator starts the control device located outside the unit. First, the multi-headed yarn is guided by the yarn guide wheel set at the top of the fixed frame and the guide wheel also set at the top of the fixed frame, so that the multi-headed yarn can be orderly inserted into the cavity opened inside the adjustment mechanism. The yarn can move in coordination with the rolling of multiple sets of yarn wheels set inside the adjustment mechanism. When passing through the adjustment mechanism, the movable linkage mechanism set at the top of the fixed frame will start the motor when the main body is running, and transmit the rotational force to the yarn roller set inside the fixed frame through the belt and pulley.

[0007] Furthermore, an adjustment mechanism is connected to one end of the first connecting rod. The adjustment mechanism includes a fixed plate, a yarn wheel, and comb teeth. Both sides of the fixed plate are connected to one end of the first connecting rod. The yarn wheel is disposed inside the fixed plate. The comb teeth are disposed at the bottom end of the fixed plate. A first gear is disposed at one end of the yarn wheel. A second gear meshes with the outside of the first gear. A rotating rod is fixed inside the second gear. A vortex blade is fixed to the outside of the rotating rod. The material connecting the comb teeth and the fixed plate is silicone. A guide wheel is disposed at the top of the fixed frame.

[0008] By adopting the above technical solution, the rotation of the yarn roller itself causes the irregularly shaped cams set at both ends of the yarn roller to rotate at a synchronous rate. When the irregularly shaped cams rotate, because the rollers are engaged with the first spring at one end, the rollers will always be in close contact with the irregularly shaped cams. Through the uniform rotation of the irregularly shaped cams, the sinusoidal wave surface of the outer edge of the irregularly shaped cams will continuously undulate. This will cause the first spring to extend and retract to a certain extent through the rollers, thereby causing the L-shaped rod to sway slightly. In conjunction with the rotating rod set at the top of the L-shaped rod, the first connecting rod located at the top of the second connecting rod will sway slightly.

[0009] Furthermore, the top of the main body is provided with multiple sets of fixed seats, the top of the fixed frame is provided with multiple sets of yarn guide wheels, the fixed frame is provided with a motor, and the output end of the motor is connected to a belt.

[0010] By adopting the above technical solution, a torsion spring is set at the connection between the first link and the second link. Therefore, when the L-shaped rod transmits the slight shaking force to the first link, although the first link will also shake slightly, the amplitude and speed of the shaking will be greatly reduced due to the torsion spring set at one end. However, when the first link shakes, it will drive the fixed plate set at its top to swing slightly, so that the multiple sets of yarns sliding inside the fixed plate will be driven by the fixed plate to shake slightly up and down, thereby stabilizing the yarn tension within a certain range. That is, when the yarn is slack (tension decreases), the trough of the shaped cam pushes the swing arm, the yarn roller decelerates, and the yarn tightens; when the yarn is taut (tension increases), the peak of the shaped cam lifts the swing arm, the yarn feeding roller accelerates, and the yarn is released.

[0011] Furthermore, a pulley is provided at the top of the fixing frame, and the pulley cooperates with the belt. A protective shell is provided on one side of the fixing frame, and the protective shell cooperates with the belt. A suction bucket is provided inside the fixing frame, and two sets of bearing seats are provided at the top of the fixing frame.

[0012] By adopting the above technical solution, when the yarn lint gets tangled on the surface of the yarn roller during normal operation, the rotational resistance of the yarn roller increases, the torque of the transmission shaft increases, and the rotational speed of the coaxially fixed irregular cam fluctuates. As a result, the increased resistance causes the pressure of the irregular cam on the roller to increase sharply, and the increased torque causes the rotation of the irregular cam to be more stuck. At this time, the irregular cams set at both ends of the yarn roller, due to their special shape and their jerky rotational speed, will cause the roller to be unable to roll smoothly on their slope. Moreover, when the irregular cam continues to rotate, its slope will forcefully push up the roller.

[0013] Furthermore, a first filter screen is provided inside the suction barrel, a second filter screen is provided inside the suction barrel, a torsion spring is provided between the first connecting rod and the second connecting rod, and a cavity is provided inside the L-shaped rod to cooperate with the limiting rod.

[0014] By adopting the above technical solution, the roller is pried upward by the rotation of the irregular cam. When it is pried upward, the L-shaped rod connected to it, as well as the first and second springs set inside the L-shaped rod, will be compressed to a certain extent. This facilitates the angle change of the L-shaped rod and transmits the prying force to the first connecting rod. Through the adjustment mechanism set at one end of the first connecting rod, a large-amplitude shaking is performed, which drives the multiple sets of comb teeth set at the bottom of the fixed plate to move into the yarn roller along a fixed path. The grooves set inside the yarn roller are matched with the size and number of comb teeth, which facilitates the comb teeth to hook out the entangled fibers in the grooves. The silicone layer at the root of the comb teeth can also shake off impurities through high-frequency vibration, thereby achieving a self-cleaning effect. After the subsequent completion, the comb teeth can be reset by the torsion springs of the first and second connecting rods, pulling them back to their original positions.

[0015] In summary, the present invention has the following beneficial effects: The present invention guides multi-headed yarns through a yarn guide wheel and a flow guide wheel, which then sequentially feed the yarn into the cavity of the adjustment mechanism. The yarn wheel rolls in conjunction with the yarn movement. A motor drives the yarn roller to rotate via a belt, and a shaped cam rotates synchronously, pushing the roller to compress the spring. This causes the L-shaped rod to sway slightly, which, after being buffered by a torsion spring, causes the fixed plate to swing slightly, stabilizing the yarn tension. When the yarn is slack, the trough pushes the swing arm to decelerate and tighten; when it is taut, the crest pushes the swing arm to accelerate and release. When yarn fibers become entangled in the yarn roller, the resistance increases, and the shaped cam rotates abruptly, prying the roller. The compressed spring drives the comb teeth to shift, hooking out the entangled fibers in the grooves and vibrating to shake off impurities. Simultaneously, the first gear drives the second gear, causing the vortex blades to rotate at high speed, generating negative pressure that draws the fibers into the suction bucket. After being filtered by a stainless steel mesh and non-woven fabric, dynamic tension balance is achieved, improving cleaning efficiency and preventing fiber entanglement. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of the present invention will now be described.

[0028] A yarn feeding device for a spinning machine with traction function, such as Figures 1-9As shown, the device includes a main body 1, a fixed frame 2 at the top of the main body 1, a yarn roller 3 at the top of the fixed frame 2, a shaped cam 16 inside the yarn roller 3, and a movable linkage mechanism 5 at the top of the fixed frame 2. The movable linkage mechanism 5 includes a roller 501, a movable frame 502, a first spring 503, an L-shaped rod 504, a limiting rod 505, a second spring 506, a rotating rod 507, a first connecting rod 508, and a second connecting rod 509. The roller 501 is located inside the movable frame 502 and cooperates with the shaped cam 16. The movable frame 502 is located on one side of the L-shaped rod 504. The first spring 503 is located at one end of the L-shaped rod 504. The L-shaped rod 504 is located on one side of the limiting rod 505. The limiting rod 505 is connected to the top of the fixed frame 2. The second spring 506 is located on the L-shaped rod 509. Inside the rod 504, the rotating rod 507 is located inside the L-shaped rod 504. The first connecting rod 508 is located at the other end of the rotating rod 507, and the second connecting rod 509 is connected to the top of the fixed frame 2. The multi-headed yarn is guided by the yarn guide wheel 8 located at the top of the fixed frame 2 and the guide wheel 15 located at the top of the fixed frame 2, so that the multi-headed yarn can be orderly inserted into the cavity opened inside the adjustment mechanism 4. The yarn can move by the rolling of the multiple sets of yarn wheels 402 located inside the adjustment mechanism 4. When passing through the adjustment mechanism 4, the movable connecting rod mechanism 5 located at the top of the fixed frame 2 will be activated by the motor 11 when the main body 1 is running, and the rotational force will be transmitted to the yarn roller 3 located inside the fixed frame 2 through the belt 12 and the pulley 7.

[0029] For example, one end of the first connecting rod 508 is connected to an adjusting mechanism 4. The adjusting mechanism 4 includes a fixed plate 401, a yarn wheel 402, and comb teeth 403. Both sides of the fixed plate 401 are connected to one end of the first connecting rod 508. The yarn wheel 402 is disposed inside the fixed plate 401, and the comb teeth 403 are disposed at the bottom end of the fixed plate 401. One end of the yarn roller 3 is provided with a first gear 17, and a second gear 20 meshes with the outer side of the first gear 17. A rotating rod 21 is fixed inside the second gear 20, and a vortex blade 18 is fixed to the outer side of the rotating rod 21. The material connecting the comb teeth 403 and the fixed plate 401 is silicone. A guide wheel 15 is provided at the top of the fixed frame 2. The yarn roller 3 rotates to make the yarn roller 3 rotate. The irregularly shaped cams 16 at both ends of the yarn roller 3 rotate synchronously. When the irregularly shaped cams 16 rotate, the roller 501 will always be in close contact with the irregularly shaped cam 16 because of the first spring 503 at one end of the roller 501. The uniform rotation of the irregularly shaped cam 16 causes the sinusoidal wave surface of the outer edge of the irregularly shaped cam 16 to continuously undulate. This causes the first spring 503 to extend and retract to a certain extent through the roller 501, which causes the L-shaped rod 504 to sway slightly. Through the cooperation of the rotating rod 507 at the top of the L-shaped rod 504, the first connecting rod 508, which is movably connected to the top of the second connecting rod 509, sways slightly.

[0030] For example, the top of the main body 1 is provided with multiple sets of fixing seats 10, the top of the fixing frame 2 is provided with multiple sets of yarn guiding wheels 8, the fixing frame 2 is provided with a motor 11, and the output end of the motor 11 is sleeved with a belt 12. Because a torsion spring is provided at the connection between the first connecting rod 508 and the second connecting rod 509, when the L-shaped rod 504 transmits a slight swaying force to the first connecting rod 508, although the first connecting rod 508 will also sway slightly, the amplitude and speed of the swaying will be greatly reduced due to the torsion spring at one end. When the first link 508 shakes, it will cause the fixed plate 401 at its top to swing slightly. This will cause the multiple sets of yarns sliding inside the fixed plate 401 to swing slightly up and down, thereby stabilizing the yarn tension within a certain range. When the yarn is slack (tension decreases), the trough of the shaped cam 16 pushes the swing arm, the yarn roller 3 decelerates, and the yarn tightens. When the yarn is taut (tension increases), the crest of the shaped cam 16 lifts the swing arm, the yarn feed roller 3 accelerates, and the yarn is released.

[0031] For example, the top of the fixing frame 2 is provided with a pulley 7, which cooperates with the belt 12; a protective shell 14 is provided on one side of the fixing frame 2, which cooperates with the belt 12; a suction tube 9 is provided inside the fixing frame 2; and two sets of bearing seats 6 are provided at the top of the fixing frame 2.

[0032] For example, the suction barrel 9 is provided with a first filter 13 and a second filter 19. A torsion spring is provided between the first connecting rod 508 and the second connecting rod 509. The L-shaped rod 504 is provided with a cavity that cooperates with the limiting rod 505. When the subsequent yarn roller 3 is running normally, when yarn lint is wrapped around the surface of the yarn roller 3, the rotational resistance of the yarn roller 3 increases, the torque of the transmission shaft increases, and the rotational speed of the coaxial fixed irregular cam 16 fluctuates. As a result, the increased resistance causes the pressure of the irregular cam 16 on the roller 501 to increase sharply, and the increased torque causes the rotation of the irregular cam 16 to be more stuck. At this time, the irregular cam 16 provided at both ends of the yarn roller 3, due to its special shape and its jerky rotational speed, will cause the roller 501 to be unable to roll smoothly on its 60-degree slope. When the irregular cam 16 continues to rotate, its 60-degree slope will forcefully push up the roller 501.

[0033] The working principle of this invention is as follows: When in use, after the main body 1 is connected to the power supply, the operator starts the control device located outside the device to operate it. First, the multi-head yarn is guided by the yarn guide wheel 8 set at the top of the fixed frame 2 and the guide wheel 15 also located at the top of the fixed frame 2, so that the multi-head yarn can be orderly inserted into the cavity opened inside the adjustment mechanism 4, and the yarn can be moved by the rolling of the multiple sets of yarn wheels 402 set inside the adjustment mechanism 4.

[0034] When passing through the adjustment mechanism 4, the movable linkage mechanism 5, which is also located at the top of the fixed frame 2, will transmit the rotational force to the yarn roller 3 located inside the fixed frame 2 through the belt 12 and pulley 7 when the main body 1 is running.

[0035] The rotation of the yarn roller 3 causes the irregularly shaped cams 16 at both ends of the yarn roller 3 to rotate at a synchronous speed. When the irregularly shaped cams 16 rotate, the roller 501 will always be in close contact with the irregularly shaped cam 16 because of the first spring 503 at one end of the roller 501. The uniform rotation of the irregularly shaped cam 16 causes the sinusoidal wave surface of the outer edge of the irregularly shaped cam 16 to continuously undulate. This causes the first spring 503 to extend and retract to a certain extent through the roller 501, which causes the L-shaped rod 504 to sway slightly. With the cooperation of the rotating rod 507 at the top of the L-shaped rod 504, the first connecting rod 508, which is movably connected to the top of the second connecting rod 509, will sway slightly.

[0036] Because a torsion spring is provided at the connection between the first link 508 and the second link 509, when the L-shaped rod 504 transmits the slight shaking force to the first link 508, the first link 508 will also shake slightly. However, due to the torsion spring at one end, the amplitude and speed of the shaking will be greatly reduced. But when the first link 508 shakes, it will cause the fixed plate 401 at its top to swing slightly. This will cause the multiple sets of yarns sliding inside the fixed plate 401 to be driven by the fixed plate 401 to shake slightly up and down, thereby stabilizing the yarn tension within a certain range. When the yarn is slack (tension decreases), the trough of the shaped cam 16 pushes the swing arm, the yarn roller 3 decelerates, and the yarn tightens. When the yarn is taut (tension increases), the crest of the shaped cam 16 lifts the swing arm, the yarn feed roller 3 accelerates, and the yarn is released.

[0037] When the yarn roller 3 is running normally, when yarn lint gets tangled on the surface of the yarn roller 3, the rotational resistance of the yarn roller 3 increases, the torque of the transmission shaft increases, and the rotational speed of the coaxially fixed irregular cam 16 fluctuates. As a result, the increased resistance causes the pressure of the irregular cam 16 on the roller 501 to increase sharply, and the increased torque causes the rotation of the irregular cam 16 to be more stuck. At this time, the irregular cam 16 set at both ends of the yarn roller 3, due to its special shape and its jerky rotational speed, will cause the roller 501 to be unable to roll smoothly on its 60-degree slope. When the irregular cam 16 continues to rotate, its 60-degree slope will forcefully push up the roller 501.

[0038] This causes the roller 501 to be pried upward by the rotation of the shaped cam 16. When it is pried upward, the L-shaped rod 504 connected to it, as well as the first spring 503 and the second spring 506 inside the L-shaped rod 504, will be compressed to a certain extent. This facilitates the angle change of the L-shaped rod 504 and transmits the prying force to the first connecting rod 508. Through the adjustment mechanism 4 at one end of the first connecting rod 508, it will shake significantly, causing... The multiple sets of comb teeth 403 set at the bottom of the fixed plate 401 are moved into the yarn roller 3 along a fixed path. The grooves set inside the yarn roller 3 are matched with the size and number of comb teeth 403, which makes it easy for the comb teeth 403 to hook out the entangled fibers in the grooves. The silicone layer at the root of the comb teeth 403 can also shake off impurities through high-frequency vibration, thereby achieving a self-cleaning effect. After the subsequent completion, it can be reset by the torsion spring of the first connecting rod 508 and the second connecting rod 509, pulling the comb teeth 403 back to the original position.

[0039] After the subsequent comb teeth 403 shake off the entangled fibers in the grooves, the suction barrel 9 fixed inside the fixed frame 2 and the yarn roller 3 rotate, which drives the first gear 17, coaxially fixed at one end, to rotate at high speed. The first gear 17 has a second gear 20 meshing on its outer side. When the first gear 17 drives the second gear 20 to rotate, the rotating rod 21 inside the second gear 20 also synchronously drives the vortex blade 18 fixed at one end to rotate at high speed. And because the first gear... The transmission ratio between gear 17 and second gear 20 is 1:2, so the rotation speed of vortex blade 18 is twice that of yarn roller 3. At this time, the rotation of vortex blade 18 will generate a strong negative pressure suction force, and the entangled fibers will be sucked into the suction barrel 9 through the opening of the suction barrel 9. The suction barrel 9 is also equipped with a first filter screen 13 and a second filter screen 19. The first filter screen 13 is a stainless steel mesh, which intercepts lint, while the second filter screen 19 is a non-woven fabric, which adsorbs dust.

[0040] The above structure achieves the functions of maintaining dynamic tension balance, significantly improving dust removal and cleaning efficiency, and triggering anti-entanglement when fibers become entangled.
