Description

Technical Field

[0001] This utility model relates to the field of air-jet spinning, and in particular to a traverse mechanism for an air-jet spinning machine. Background Technology

[0002] In the textile industry, the performance and stability of the air-jet spinning machine, as a high-efficiency and automated spinning equipment, directly affect the quality of yarn and production efficiency. The traverse mechanism of the air-jet spinning machine is one of the key components in the spinning process. It is mainly responsible for the lateral movement of the yarn during the winding process to ensure that the yarn can be wound evenly on the take-up roller and avoid yarn accumulation or irregular winding.

[0003] However, the existing traverse mechanism of air-jet spinning machines still has some shortcomings in design and use. First, the traditional traverse mechanism is relatively cumbersome to install and disassemble. Usually, these mechanisms are fixed with fasteners such as bolts, which not only increases the time cost of installation and disassembly, but also requires operators to have certain professional skills and experience. During daily maintenance and repair, frequent bolt disassembly and assembly not only increases the labor intensity of workers, but may also cause damage to parts or a decrease in installation accuracy due to improper operation, thereby affecting the overall performance of the spinning machine.

[0004] Secondly, the traverse mechanism generates a certain amount of debris during operation, mainly from yarn fiber shedding. Most methods address this debris issue manually; however, manual cleaning is not only inefficient but also difficult to guarantee timely removal. If this debris is not cleaned promptly, it may accumulate on various components of the traverse mechanism, leading to increased wear, increased resistance, and even jamming. This not only affects the normal operation of the spinning machine but also shortens its lifespan and increases maintenance and replacement costs for the company.

[0005] Therefore, it is necessary to provide a new traverse mechanism for air-jet spinning machines to solve the above-mentioned technical problems. Utility Model Content

The slider is slidably connected to the outer wall of the guide rod. The side of the slider away from the cam column is fixedly connected to the guide ring through a connecting plate. A protruding rod is slidably connected inside the side of the slider close to the cam column. One end of the protruding rod close to the cam column is placed in a cam groove opened on the outer wall of the cam column. A second spring is sleeved on the outer wall of the protruding rod. One end of the second spring is fixedly connected to the outer wall of the protruding rod, and the other end is fixedly connected to the inner wall of the slider.

[0011] Preferably, the top of the slider has a through hole, and a pressing rod is inserted into the hole. The outer wall of the pressing rod contacts the end of the protrusion away from the cam post.

[0012] Preferably, the cleaning components include: a suction fan and a collection box. The suction fan is fixedly connected to the bottom of the base. The input end of the suction fan is connected to the suction nozzle through a suction pipe. The suction nozzle is fixedly connected to the connecting plate on one side of the slider. The output end of the suction fan is connected to a duct. The duct is fixedly connected to the bottom end of the base, and a sealing ring is fixedly connected to the outer wall of the end near the suction fan.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 7A traverse mechanism for an air-jet spinning machine includes: a base 1, a locking assembly, suction nozzles 4, a cleaning assembly, and a protective cover 5. A cam post 2 and a transmission system for driving the cam post 2 to rotate, as well as a guide ring 3 for guiding yarn winding, are mounted on the top of the base 1. A locking assembly is installed between the transmission system and the cam post 2 to fix the cam post 2. Suction nozzles 4 are provided on both sides of the guide ring 3. A cleaning assembly is installed between the base 1 and the suction nozzles 4, driving the suction nozzles 4 to adsorb debris generated during yarn movement. A protective cover 5 is installed on the top of the cam column 2. The protective cover 5 is located directly above the cam column 2. The locking assembly includes a trapezoidal block 6, a slot 7, and a spring 8. A motor 9 is fixedly connected to one end of the base 1. A transmission rod 10 is fixedly connected to the output end of the motor 9. An installation groove is opened in the middle of the transmission rod 10. Trapezoidal blocks 6 are symmetrically slidably connected inside the installation groove. Springs 8 are symmetrically fixedly connected between opposite ends of the trapezoidal blocks 6. Slots 7 are symmetrically opened inside the cam column 2. The slots 7 lock with the corresponding trapezoidal blocks 6. The outer wall of the transmission rod 10 is symmetrically provided with protrusions. The cam column 2 is sleeved on the transmission rod 10. The outer wall of rod 10 is slidably connected to it. A guide rod 11 is fixedly connected to the top of the base 1. A slider 12 is sleeved on the outer wall of the guide rod 11. The slider 12 is slidably connected to the outer wall of the guide rod 11. The side of the slider 12 away from the cam column 2 is fixedly connected to the guide ring 3 through a connecting plate. A protruding rod 13 is slidably connected inside the side of the slider 12 near the cam column 2. One end of the protruding rod 13 near the cam column 2 is placed in a cam groove opened on the outer wall of the cam column 2. A spring 14 is sleeved on the outer wall of the protruding rod 13. One end of the spring 14 is fixedly connected to the outer wall of the protruding rod 13, and the other end is connected to the slider. The inner wall of the slider 12 is fixedly connected. The top of the slider 12 has a circular hole that passes through the slider 12. A pressing rod 15 is inserted into the circular hole. The outer wall of the pressing rod 15 contacts the end of the protruding rod 13 away from the cam column 2. The end of the base 1 away from the motor 9 is symmetrically connected to a support plate 18. A tension spring 19 is fixedly connected between the opposite ends of the support plates 18. The top of the base 1 is slidably connected to a trapezoidal plate 20 near the support plate 18. The sliding direction of the trapezoidal plate 20 is perpendicular to the sliding direction of the support plate 18, and one end of the trapezoidal plate 20 is placed between the two support plates 18.

[0030] It should be noted that after disassembly, the cam pins 2 with different strokes to be installed are fitted onto the transmission rod 10, ensuring that the inner contour of the cam pin 2 corresponds to the protrusion on the outer wall of the transmission rod 10. The cam pin 2 is pushed to move closer to the motor 9, so that the trapezoidal block 6 inside the mounting slot engages with the slot 7 inside the cam pin 2. The slider 12 is moved so that one end of the protrusion 13 is aligned with the cam groove on the outer wall of the cam pin 2. The pressing rod 15 is inserted into the round hole at the top of the slider 12. The insertion of the pressing rod 15 will cause its bottom end to gradually press the protrusion 13 into the cam groove. At this time, the spring 14 will be compressed until the pressing rod 15 is fully inserted into the round hole, and the end of the protrusion 13 is placed back into the cam groove, realizing the connection between the protrusion 13 and the cam pin 2. The trapezoidal plate 20 at the end of the base 1 is pulled to move in the opposite direction. Under the tension of the tension spring 19, the support plates 18 will move closer to each other, supporting and fixing the transmission rod 10 again. At this time, the installation of the cam pins 2 with different strokes is completed.

[0031] Please see Figure 4 and Figure 6 The cleaning components include: a suction fan 16 and a collection box 17. The suction fan 16 is fixedly connected to the bottom of the base 1. The input end of the suction fan 16 is connected to the suction nozzle 4 through a suction pipe. The suction nozzle 4 is fixedly connected to the connecting plate on one side of the slider 12. The output end of the suction fan 16 is connected to a duct. The duct is fixedly connected to the bottom end of the base 1, and a sealing ring is fixedly connected to the outer wall of the end near the suction fan 16. The collection box 17 is slidably connected to the bottom of the base 1. The other end of the duct is inserted into the interior of the collection box 17, and the sealing ring on its outer wall contacts the end outer wall of the collection box 17.

[0032] It should be noted that: the end of the collection box 17 near the suction fan 16 has an exhaust port, and a filter screen is installed inside the collection box near the exhaust port to intercept the adsorbed debris from re-entering the external environment; the end of the collection box 17 below the exhaust port has a connection hole that allows the conduit to pass through. In the working state, the conduit is placed inside the collection box 17, and the sealing ring fixed on its outer wall contacts the end of the collection box 17 to achieve a seal.

[0033] The working principle of the traverse mechanism of the airflow spinning machine provided by this utility model is as follows:

[0034] Work status:

[0035] When the equipment is started, the motor 9 starts to run, and its output end drives the fixedly connected transmission rod 10 to rotate at high speed; in the mounting groove opened in the middle of the transmission rod 10, trapezoidal blocks 6 are symmetrically slidably connected. Under the action of the spring 8, the two trapezoidal blocks 6 are initially in an outward extension state.

[0036] The cam post 2, which is fitted onto the outer wall of the transmission rod 10, has symmetrically opened grooves 7 inside that match the trapezoidal block 6. During installation, the trapezoidal block 6 is engaged with the grooves 7, so when the transmission rod 10 rotates, the cam post 2 will rotate synchronously with the transmission rod 10. The symmetrically arranged protrusions on the outer wall of the transmission rod 10 play a positioning and guiding role during the fitting of the cam post 2, ensuring that the cam post 2 is installed in an accurate position and can rotate stably with the transmission rod 10.

[0037] A guide rod 11 is fixed to the top of the base 1. A slider 12 is sleeved on the outer wall of the guide rod 11. The slider 12 can slide freely on the guide rod 11. A protruding rod 13 is slidably connected to the side of the slider 12 near the cam column 2. The end of the protruding rod 13 is placed in the cam groove opened on the outer wall of the cam column 2.

[0038] A pressing rod 15 is inserted into the round hole at the top of the slider 12. The outer wall of the pressing rod 15 contacts the end of the protrusion 13 away from the cam post 2. At this time, the spring 14 is in a compressed state. During the rotation of the cam post 2, the shape of the cam groove on its outer wall will change continuously, thereby driving the protrusion 13 to slide back and forth inside the slider 12.

[0039] Since the protruding rod 13 is connected to the slider 12, the reciprocating sliding of the protruding rod 13 will drive the slider 12 to reciprocate along the axial direction of the guide rod 11; the other side of the slider 12 is fixedly connected to the guide ring 3 through the connecting plate. Under the reciprocating motion of the slider 12, the guide ring 3 will drive the yarn to move laterally during the winding process, ensuring that the yarn can be evenly wound on the collecting roller, avoiding yarn accumulation or irregular winding phenomenon.

[0040] During the movement of the yarn, a certain amount of debris is generated, which mainly comes from the shedding of yarn fibers. In order to clean up these debris in time, a suction fan 16 is fixedly connected to the bottom of the base 1.

[0041] The input end of the suction fan 16 is connected to the suction nozzle 4 through the suction pipe. The suction nozzle 4 is fixedly connected to the connecting plate on one side of the slider 12 and is located on both sides of the guide ring 3. When the suction fan 16 is started, it will generate a strong suction force, which will suck away the debris generated during the movement of the yarn through the suction nozzle 4.

[0042] The sucked-up debris is transported through the suction pipe to the output end of the suction fan 16, and then transported through the conduit to the collection box 17. The collection box 17 is slidably connected to the bottom of the base 1. The conduit is inserted into the collection box 17, and the sealing ring on the outer wall of the conduit contacts the outer wall of the end of the collection box 17 to ensure that the debris does not leak and to prevent the debris from scattering everywhere and affecting the working environment and normal operation of the equipment.

[0043] Disassembly process:

[0044] When it is necessary to replace the cam column 2 with a different stroke, first, turn off the motor 9 and the suction fan 16 to ensure that the equipment is stopped and to avoid accidents during the disassembly process;

[0045] Rotate the protective cover 5 on the top of the cam column 2 to open it, which facilitates the subsequent disassembly operation. The support plate 18 is symmetrically slidably connected to the end of the base 1 away from the motor 9. The opposing ends of the support plates 18 are fixedly connected with tension springs 19. Before disassembly, the support plate 18 is in the state of supporting the transmission rod 10.

[0046] The trapezoidal plate 20, which is slidably connected to the end of the base 1, is pushed. The sliding direction of the trapezoidal plate 20 is perpendicular to the sliding direction of the support plate 18, and one end of the trapezoidal plate 20 is placed in the middle of the two support plates 18. The movement of the trapezoidal plate 20 will push the support plates 18 away from each other and stretch the tension spring 19, thereby releasing the support effect of the support plates 18 on the transmission rod 10 and creating conditions for the subsequent disassembly of the cam column 2.

[0047] Pull out the pressing rod 15 at the top of the slider 12. During the pulling process, the outer wall of the pressing rod 15 gradually separates from the protrusion 13. Since the second spring 14 was in a compressed state before, when the outer wall of the pressing rod 15 separates from the protrusion 13, under the elastic force of the second spring 14, the protrusion 13 will slide inside the slider 12 and move away from the cam post 2 until the end of the protrusion 13 completely separates from the cam groove, thereby disconnecting the connection between the protrusion 13 and the cam post 2 and interrupting the power transmission between the slider 12 and the cam post 2.

[0048] Hold the cam post 2 and pull it away from the motor 9. During this process, the slot 7 inside the cam post 2 will squeeze the trapezoidal block 6 that is slidably connected inside the transmission rod 10. Since there is a snap-fit ​​relationship between the trapezoidal block 6 and the slot 7, under the squeezing action, the trapezoidal blocks 6 will move closer to each other and compress the spring 8. As the cam post 2 continues to be pulled, the trapezoidal block 6 will completely disengage from the slot 7. At this time, the connection between the cam post 2 and the transmission rod 10 is released. After continuing to pull the cam post 2 to disengage it from the transmission rod 10, the disassembly is complete. At this time, it is ready to install cam posts 2 with different strokes.

[0049] Installation process:

[0050] The cam post 2 with different strokes to be installed is fitted onto the transmission rod 10, ensuring that the inner contour of the cam post 2 corresponds to the protrusion on the outer wall of the transmission rod 10; the protrusion can play a positioning and guiding role, ensuring that the cam post 2 is installed in an accurate position and can rotate stably with the transmission rod 10.

[0051] The cam column 2 is pushed towards the motor 9. During the pushing process, the end of the cam column 2 will contact and press the trapezoidal block 6. Since the trapezoidal block 6 can slide in the mounting groove in the middle of the transmission rod 10, under the pressing action, the trapezoidal block 6 will retract into the mounting groove. At this time, the spring 8 is compressed. Continue to push the cam column 2 until the spring 8 releases its elastic force, pushing the trapezoidal block 6 to engage with the slot 7 inside the cam column 2. At this time, the cam column 2 and the transmission rod 10 are stably connected and will rotate synchronously with the transmission rod 10.

[0052] Move slider 12 so that one end of protruding rod 13 is aligned with the cam groove on the outer wall of cam post 2; this is to re-establish the power transmission relationship between slider 12 and cam post 2 later; insert extrusion rod 15 into the round hole opened at the top of slider 12. The insertion of extrusion rod 15 will cause its bottom end to gradually extrude protruding rod 13 into the cam groove; at this time, spring 14 will be compressed until extrusion rod 15 is fully inserted into the round hole, and the end of protruding rod 13 is placed back in the cam groove, realizing the connection between protruding rod 13 and cam post 2;

[0053] Pull the trapezoidal plate 20 at the end of the base 1 to move in the opposite direction. Under the tension of the tension spring 19, the support plates 18 will move closer to each other, supporting and fixing the transmission rod 10 again, ensuring the stability of the entire traverse mechanism during operation. At this time, the cam columns 2 of different strokes are installed. Rotate the protective cover 5 to position it above the cam column 2, and the equipment can be restarted to carry out normal spinning work.
