Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to a high-precision, high-consistency single-sided knitting needle polishing device and its usage method. Background Technology

[0002] In the textile machinery industry, knitting needles, as core components, directly affect the quality of textiles and production efficiency through their surface quality. With the rapid development of the textile industry, the market demand for high-precision, high-consistency knitting needles is increasing daily. However, existing knitting needle polishing technologies have many shortcomings. Traditional manual polishing methods heavily rely on worker experience, resulting in low efficiency and difficulty in ensuring consistent polishing quality for each needle, leading to poor product precision and consistency. While semi-automatic polishing equipment improves efficiency to some extent, it cannot achieve uniform polishing when dealing with complex-shaped, tiny needles. Automated polishing technologies, which have emerged in recent years, offer some improvement in precision, but the equipment is generally complex in structure, expensive, and difficult to maintain, making it unaffordable for small and medium-sized enterprises. Furthermore, existing technologies are inadequate in fixing and positioning knitting needles, failing to precisely control their position during the polishing process, further affecting polishing precision and consistency. These problems limit the development of the textile industry, necessitating a new knitting needle polishing technology to address them. Summary of the Invention

[0008] Preferably, the other end of the threaded rod is threadedly connected to a slider, the top end of the slider is fixedly connected to a clamping and positioning mechanism, and both ends of the threaded rod are rotatably connected to the inside of the operating table.

[0009] Preferably, the clamping and positioning mechanism includes a base plate, the lower surface of which is disposed at the top of the slider, the outer wall of the slider is slidably connected with a groove, the upper surface of the base plate is provided with a motor three, the output end of the motor three is fixedly provided with a pulley five, and the pulley five is internally connected with a belt three.

[0010] Preferably, one end of the belt three is connected to a pulley six, a rotating shaft two is provided in the middle of the pulley six, and a gear is provided at the bottom end of the rotating shaft two, with several teeth meshing at the ends of the gear.

[0011] Preferably, one end of the tooth is provided with a clamping rod, one side of the clamping rod is provided with a slide bar, the outer wall of the slide bar is slidably connected to a second outer shell, the top end of the clamping rod is provided with a plurality of magnetic blocks, one side of the magnetic blocks is provided with a slot, and the slot of the magnetic blocks matches the knitting needle.

[0012] Preferably, the bottom of the operating table is provided with several legs, which are used to support the operating table.

[0013] A method for using a high-precision, high-consistency single-sided knitting needle polishing device, the method comprising the following steps: S1. Place the knitting needle to be polished into the magnetic block slot and fix it to the top of the clamping bar using the magnetic block. S2. Start motor three. Motor three drives pulley five to rotate, which in turn drives pulley six to rotate, thereby causing the gear at the bottom of shaft two to move and adjust the positioning. S3. Start motor one. Motor one drives threaded rod one to rotate, causing the guide block and the connected support frame to move up and down, and adjust the height of the polishing wheel. S4. Start motor two. Motor two drives pulley three to rotate, which in turn drives pulley four to rotate, thereby driving shaft one and polishing wheel to rotate at high speed. S5. Turn on the fan, and the cooling air will blow towards the polishing area through the air duct, air outlet duct and air nozzle; S6. Start the power source connected to pulley one, drive pulley one to rotate, drive pulley two to rotate through belt one, and drive threaded rod two to rotate, so that the slider and clamping positioning mechanism move horizontally, so that the knitting needle contacts the rotating polishing wheel and polishes it.

[0014] Working principle: In the needle fixing stage, the magnetism of the magnetic block is used to attract the needle to be polished into the slot at the top of the clamping bar, achieving quick and stable fixation. Starting motor three drives pulley five to rotate, which in turn drives pulley six via belt three. This, in turn, causes the gear at the bottom of shaft two to move, adjusting and positioning the clamping bar to ensure the needle is in the ideal polishing position.

[0015] In terms of component adjustment, once the motor starts, it drives the threaded rod to rotate, causing the guide block and the connected support frame to move up and down, thereby adjusting the height of the polishing wheel to accommodate different specifications of knitting needles and ensuring full contact between the polishing wheel and the surface of the knitting needle.

[0016] Power transmission is the core of the device's operation. Motor 2 drives pulley 3 to rotate, which in turn drives pulley 4 via belt 2, causing shaft 1 and the polishing wheel to rotate at high speed, providing power for polishing. Simultaneously, the power source connected to pulley 1 starts, driving pulley 1 to rotate, which in turn drives pulley 2 via belt 1, causing the threaded rod 2 to rotate. This causes the slider and clamping positioning mechanism to move horizontally, allowing the knitting needles to contact the rotating polishing wheel for polishing.

[0017] In the cooling process, after the fan is turned on, the internal impeller rotates at high speed to draw in air, pressurizes it, and then blows it through the air duct, air outlet and nozzle to the polishing area, reducing the temperature of the polishing area and blowing away debris and dust to ensure polishing quality.

[0018] Through these mutually cooperating working principles, the entire device achieves high-precision and high-consistency polishing of single-sided knitting needles, solving problems such as poor polishing precision and consistency and complex equipment in existing technologies, and meeting the textile industry's production needs for high-quality knitting needles.

[0019] This invention provides a high-precision, high-consistency single-sided knitting needle polishing device and its usage method, which has the following beneficial effects: 1. In this invention, by controlling the rotation angle and speed of motor one, the moving distance of the guide block can be precisely adjusted, thereby precisely adjusting the vertical distance between the polishing wheel and the knitting needle. For single-sided knitting needles of different specifications, the height of the polishing wheel can be adjusted to achieve the optimal contact state between the polishing wheel and the knitting needle surface. This solves the problem of poor high-precision polishing in existing knitting needle polishing technology.

[0020] 2. In this invention, the cooling mechanism effectively reduces the temperature of the polishing area. The cooling air ejected from the nozzles of the cooling mechanism quickly removes heat from the polishing area, keeping the surface temperature of the knitting needles within a relatively low and stable range. This solves the quality problems caused by overheating.

[0021] 3. In this invention, the rotational motion of motor one is precisely converted into the horizontal linear motion of the clamping and positioning mechanism through bevel gear transmission, belt transmission, and screw transmission. This ensures that the knitting needle and polishing wheel can accurately contact each other and perform polishing operations. This solves the problems of inaccurate knitting needle positioning and inconvenient adjustment.

[0022] 4. In this invention, the movement distance and position of the clamping rod can be precisely controlled by the rotation of motor three and the belt and gear transmission, thus accurately clamping the knitting needle in the appropriate position. The magnetic block design ensures that the knitting needle is firmly fixed, preventing it from shaking or shifting during polishing. Simultaneously, this clamping method allows for convenient and rapid clamping and positioning of knitting needles of different specifications, improving work efficiency. It solves the problems of unstable and inconsistent needle clamping. Attached Figure Description

[0025] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see the appendix Figure 1 - Appendix Figure 5 Appendix Figure 8 This invention provides a high-precision, high-consistency single-sided knitting needle polishing device, including an operating table 1. A housing 3 is mounted on the upper surface of the operating table 1. A motor 4 is mounted on the top of the housing 3. A threaded rod 12 is fixedly mounted through the output end of the motor 4 through the housing 3. A cooling mechanism is mounted on one side of the top of the housing 3. A guide block 35 is threadedly connected to the outer wall of the threaded rod 12. A support frame 7 is fixedly mounted on one end of the guide block 35. A motor 22 is fixedly mounted on the inner wall of the support frame 7. A pulley 23 is fixedly mounted on the output end of the motor 22. A belt 24 is connected inside the pulley 23. A pulley 45 is connected to one end of the belt 24. A rotating shaft 9 is mounted in the middle of the pulley 45. A polishing wheel 8 is mounted through the outer wall of the rotating shaft 9 through the support frame 7.

[0027] Specifically, when the height of the polishing wheel 8 needs to be adjusted, the operator starts motor 4. Motor 4 serves as the power source, with its output shaft passing through the outer casing 3 and fixedly connected to the threaded rod 12. After motor 4 is powered on, the interaction between the stator and rotor inside generates a rotating magnetic field, causing the motor shaft to rotate, which in turn drives the threaded rod 12 to rotate. The threaded rod 12 is connected to the guide block 35 via a threaded engagement. Due to the characteristics of the thread, when the threaded rod 12 rotates, the guide block 35 moves along the axial direction of the threaded rod 12. This utilizes the principle of helical transmission, converting the rotational motion of the motor into the linear motion of the guide block 35. One end of the guide block 35 is fixedly connected to the support frame 7, so the movement of the guide block 35 causes the support frame 7 to move up and down together.

[0028] When polishing of the knitting needles is required, motor 22 is activated. The electromagnetic structure inside motor 22 generates electromagnetic force upon energization, driving the motor shaft to rotate. This rotation of the motor shaft causes pulley 3 23 to rotate. Pulley 3 23 interacts with belt 24 through friction; as pulley 3 23 rotates, it causes belt 24 to slide on its surface. The other end of belt 24 is connected to pulley 4 25, which also transmits power to pulley 4 25 through friction, causing it to rotate as well. Shaft 1 9 is fixedly connected to the middle of pulley 4 25, so the rotation of pulley 4 25 causes shaft 1 9 to rotate synchronously. The polishing wheel 8 is mounted on the outer wall of shaft 1 9, so the rotation of shaft 1 9 ultimately drives the polishing wheel 8 to rotate at high speed. This utilizes the principle of belt drive to transmit power from motor 22 to the polishing wheel 8.

[0029] By controlling the rotation angle and speed of motor 4, the moving distance of guide block 35 can be precisely adjusted, thereby precisely adjusting the vertical distance between polishing wheel 8 and knitting needle. For single-sided knitting needles of different specifications, even with slight differences in length, thickness, or shape, the height of polishing wheel 8 can be adjusted to achieve optimal contact between polishing wheel 8 and the knitting needle surface. This solves the problem of poor high-precision polishing in existing knitting needle polishing technology.

[0030] Please see the appendix Figure 1 -Appendix Figure 4 Appendix Figure 8 The cooling mechanism includes a fan 5, the bottom of which is located at the top of the outer casing 3. A duct 6 is fixedly installed at the output end of the fan 5. An air outlet duct 10 is installed at one end of the duct 6. Several air nozzles 11 are installed on the outer wall of the air outlet duct 10.

[0031] Specifically, when the polishing device starts working, the blower 5 is activated. The impeller inside the blower 5 rotates at high speed driven by a motor, drawing air in through the inlet of the blower 5 via centrifugal force or other fluid dynamics principles. After being accelerated and pressurized inside the blower 5, the air is discharged from the outlet. The discharged air enters the duct 6, which serves as an air transmission channel, guiding the airflow towards the outlet duct 10. Due to the constraint and guidance effect of the duct 6, the air can flow relatively stably within the pipe, reducing leakage and energy loss during transmission.

[0032] When air reaches the air outlet duct 10, it is ejected at high speed from the air outlet duct 10 under pressure due to the presence of several air nozzles 11 on its outer wall. The design of the air nozzles 11 allows air to be sprayed at a specific angle and velocity onto the polishing contact area between the polishing wheel 8 and the knitting needle. By rationally designing the number, distribution, and spray angle of the air nozzles 11, it can be ensured that the cooling air can evenly cover all parts of the polishing area.

[0033] The cooling mechanism effectively reduces the temperature of the polishing area. During polishing, the high-speed friction between the polishing wheel 8 and the needle surface generates a large amount of heat. If this heat is not dissipated in time, it can cause the needle surface temperature to rise, potentially leading to changes in the needle material's properties, such as reduced hardness and surface oxidation. The cooling air ejected from the nozzle 11 of the cooling mechanism quickly removes the heat from the polishing area, keeping the needle surface temperature within a relatively low and stable range. This solves the quality problems caused by overheating.

[0034] Please see the appendix Figure 3 -Appendix Figure 4 Appendix Figure 6 The bottom end of threaded rod 12 passes through the outer shell 3 and the operating table 1 and is provided with bevel gear 26. The tooth end of bevel gear 26 is meshed with bevel gear 13. One end of bevel gear 13 is fixedly provided with pulley 14. Belt 15 is connected inside pulley 14. One end of belt 15 is connected with pulley 16. Threaded rod 17 is provided in the middle of pulley 16. The other end of threaded rod 17 is threadedly connected with slider 18. The top end of slider 18 is fixedly connected with clamping and positioning mechanism. The two ends of threaded rod 17 are rotatably connected inside the operating table 1.

[0035] Specifically, when motor 4 operates, it drives threaded rod 12 to rotate. Since the bottom end of threaded rod 12 passes through the outer casing 3 and the operating table 1 and is equipped with bevel gear 26, the rotation of threaded rod 12 will drive bevel gear 26 to rotate synchronously. Bevel gear 26 meshes with the teeth of bevel gear 13. According to the gear transmission principle, the rotation of bevel gear 26 will drive bevel gear 13 to rotate, and the direction of rotation will change. A pulley 14 is fixedly installed at one end of bevel gear 13, so the rotation of bevel gear 13 will drive pulley 14 to rotate. Pulley 14 is connected to pulley 16 via belt 15. Utilizing the belt transmission principle, the rotation of pulley 14 will drive belt 15 to move, thereby causing pulley 16 to rotate. A threaded rod 17 is installed in the middle of pulley 16, and the rotation of pulley 16 will drive threaded rod 17 to rotate. The threaded rod 17 is threadedly connected to the slider 18. According to the principle of screw transmission, when the threaded rod 17 rotates, the slider 18 will move linearly along the axial direction of the threaded rod 17. Since the top of the slider 18 is fixedly connected to a clamping and positioning mechanism, the linear movement of the slider 18 can drive the clamping and positioning mechanism to move horizontally, thereby realizing the adjustment of the needle position.

[0036] The rotational motion of motor 4 is precisely converted into the horizontal linear motion of the clamping and positioning mechanism through bevel gear transmission, belt transmission, and screw transmission. This transmission method can accurately control the moving distance and position of the clamping and positioning mechanism, thereby accurately moving the knitting needle to a suitable relative position with the polishing wheel 8 according to the polishing requirements, ensuring that the knitting needle and polishing wheel 8 can accurately contact each other and perform polishing operations. This solves the problems of inaccurate knitting needle positioning and inconvenient adjustment.

[0037] Please see the appendix Figure 1 -Appendix Figure 4 Appendix Figure 7 The clamping and positioning mechanism includes a base plate 27. The lower surface of the base plate 27 is set at the top of the slider 18. The outer wall of the slider 18 is slidably connected with a groove. The upper surface of the base plate 27 is provided with a motor 28. The output end of the motor 28 is fixedly provided with a pulley 29. The inside of the pulley 29 is connected to a belt 30. One end of the belt 30 is connected to a pulley 31. The middle of the pulley 31 is provided with a rotating shaft 32. The bottom end of the rotating shaft 32 is provided with a gear 33. The teeth of the gear 33 are meshed with several teeth 34. One end of the teeth 34 is provided with a clamping rod 19. One side of the clamping rod 19 is provided with a slide bar. The outer wall of the slide bar is slidably connected with a housing 21. The top of the clamping rod 19 is provided with several magnetic blocks 20. One side of the magnetic block 20 is provided with a slot. The slot of the magnetic block 20 matches the knitting needle.

[0038] Specifically, when clamping and positioning the knitting needles is required, motor 328 is activated. The electromagnetic structure inside motor 328 generates electromagnetic force after being energized, driving the motor shaft to rotate. The motor shaft then drives pulley 529, which is fixedly connected to its output end, to rotate. Pulley 529 interacts with belt 30 through friction; as pulley 529 rotates, it causes belt 30 to slide on its surface. The other end of belt 30 is connected to pulley 631, which also receives power through friction, causing it to rotate. Shaft 232 is fixedly connected to the middle of pulley 631, so the rotation of pulley 631 drives shaft 232 to rotate synchronously. A gear 33 is located at the bottom of shaft 232, so gear 33 also rotates with shaft 232. Gear 33 meshes with several teeth 34; according to the transmission principle of gear 33, its rotation drives the teeth 34 to move linearly. Since one end of the tooth 34 is equipped with a clamping rod 19, the movement of the tooth 34 will cause the clamping rod 19 to slide along the slide bar within the outer casing 21. A magnet 20 is provided at the top of the clamping rod 19, and the magnet 20 has a slot that matches the knitting needle. When the clamping rod 19 moves, the magnet 20 gradually approaches the knitting needle, using the magnetism of the magnet 20 to attract and fix the knitting needle in the slot, thereby achieving the clamping and positioning of the knitting needle.

[0039] Through the rotation of motor 28, belt drive, and gear 33, the movement distance and position of clamping rod 19 can be precisely controlled, thus accurately clamping the knitting needle in the appropriate position. The design of magnetic block 20 ensures that the knitting needle is firmly fixed, preventing it from shaking or shifting during polishing. Simultaneously, this clamping method allows for convenient and rapid clamping and positioning of knitting needles of different specifications, improving work efficiency. It solves the problems of unstable and inconsistent needle clamping.

[0040] Please see the appendix Figure 1 - Appendix Figure 2 The bottom of the operating table 1 is provided with several support legs 2, which are used to support the operating table 1.

[0041] Specifically, the support legs 2 are located at the bottom of the operating platform 1, and their working principle is based on a simple mechanical support principle. The support legs 2 are in direct contact with the ground, evenly distributing the weight of the operating platform 1 and all components mounted on it, such as the housing 3, motor 4, and polishing wheel 8, onto the ground. Each support leg 2 bears a certain proportion of the total weight, maintaining stability through its own structural strength and friction with the ground. Due to the reasonable distribution and number design of the support legs 2, they work together to provide a stable support plane for the operating platform 1, enabling the entire polishing device to remain stable during operation.

[0042] The support legs 2 ensure stable placement of the entire polishing device. Leg 2 guarantees the levelness and stability of the operating table 1, allowing all components mounted on it, especially the polishing wheel 8 and clamping and positioning mechanism for high-precision polishing, to operate in a stable environment. During polishing, the stable support prevents changes in the relative position between the knitting needles and the polishing wheel 8 caused by shaking of the operating table 1, ensuring polishing accuracy and consistency. Simultaneously, leg 2 effectively isolates ground vibrations, reducing interference from external vibrations and further improving polishing quality.

[0043] Please see the appendix Figure 9 A method for using a high-precision, high-consistency single-sided knitting needle polishing device, the method comprising the following steps: S1. Place the knitting needle to be polished into the slot of the magnetic block 20 and fix it to the top of the clamping rod 19 using the magnetic block 20. S2. Start motor 3 28. Motor 3 28 drives pulley 5 29 to rotate. Through belt 3 30, pulley 6 31 rotates, which in turn causes gear 33 at the bottom of shaft 2 32 to drive teeth 34 to move, thereby realizing the adjustment and positioning of clamp rod 19. S3. Start motor one. Motor one drives threaded rod one 12 to rotate, causing guide block 35 and connected support frame 7 to move up and down, and adjust the height of polishing wheel 8. S4. Start motor 22. Motor 22 drives pulley 3 23 to rotate, which in turn drives pulley 4 25 to rotate via belt 24, thereby driving shaft 1 9 and polishing wheel 8 to rotate at high speed. S5. Turn on the fan 5. Cooling air is blown towards the polishing area through the air duct 6, the air outlet duct 10, and the air nozzle 11. S6. Start the power source connected to pulley 14 to drive pulley 14 to rotate. This drives pulley 16 to rotate via belt 15, which in turn drives threaded rod 17 to rotate. This causes slider 18 and clamping and positioning mechanism to move horizontally, allowing the knitting needle to contact the rotating polishing wheel 8 for polishing.

[0044] Specifically, the magnetic block 20 is magnetic. Utilizing the attraction between a magnet and ferromagnetic materials, when the knitting needle to be polished is placed into the slot of the magnetic block 20, the needle will be tightly attracted into the slot. The slot matches the knitting needle, which can restrict the position of the needle and fix it at the top of the clamping rod 19.

[0045] When motor 328 is powered on, the internal electromagnetic force drives the motor shaft to rotate, which in turn drives pulley 529 to rotate. Power is transmitted between pulley 529 and belt 30 via friction, causing belt 30 to move and thus driving pulley 631 to rotate. Pulley 631 is fixedly connected to shaft 232, so shaft 232 rotates synchronously, and gear 33 mounted at the bottom of shaft 232 also rotates. Gear 33 meshes with teeth 34, and according to the transmission principle of gear 33, the rotation of gear 33 is converted into linear movement of teeth 34, thereby driving clamping rod 19 to move, achieving adjustment and positioning of clamping rod 19.

[0046] Once the motor starts, its output shaft drives the threaded rod 12 to rotate. Since the threaded rod 12 is threadedly connected to the guide block 35, according to the principle of screw drive, the rotation of the threaded rod 12 causes the guide block 35 to move along the axial direction of the threaded rod 12. The guide block 35 is fixedly connected to the support frame 7, so the support frame 7 moves up and down with the guide block 35, and the polishing wheel 8 mounted on the support frame 7 also adjusts its height accordingly.

[0047] When motor 22 is powered on, its output shaft drives pulley 3 23 to rotate. Power is transmitted between pulley 3 23 and belt 24 through friction, causing belt 24 to move, which in turn drives pulley 4 25 to rotate. Pulley 4 25 is fixedly connected to shaft 9, so shaft 9 will rotate with pulley 4 25, and the polishing wheel 8 mounted on shaft 9 will also rotate at high speed.

[0048] After the fan 5 is turned on, the impeller inside the fan 5 rotates at high speed under the drive of the motor, generating a strong suction force that draws air into the fan 5. After the air is accelerated and pressurized inside the fan 5, it is discharged from the output end of the fan 5 and enters the air duct 6. The air duct 6 guides the air flow to the air outlet duct 10, and multiple air nozzles 11 installed on the air outlet duct 10 evenly disperse the air and blow it towards the polishing area.

[0049] After the power source connected to pulley 14 is started, it drives pulley 14 to rotate. Power is transmitted between pulley 14 and belt 15 through friction, causing belt 15 to move, which in turn drives pulley 16 to rotate. Pulley 16 is fixedly connected to threaded rod 17, so threaded rod 17 rotates with pulley 16. Threaded rod 17 is threadedly connected to slider 18. According to the principle of screw transmission, the rotation of threaded rod 17 causes slider 18 to move axially along threaded rod 17. Slider 18 is fixedly connected to the clamping and positioning mechanism, so the clamping and positioning mechanism moves horizontally with slider 18, thereby bringing the knitting needle into contact with the high-speed rotating polishing wheel 8, initiating the polishing operation.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
