Description
Technical Field
[0001] This invention relates to the field of textile machinery technology, specifically to a device for controlling the consistency of needle hook size in a transfer needle. Background Technology
[0002] Textile machinery refers to the various equipment used in all stages of the textile process to process natural or chemical fibers into textiles. In the field of textile machinery, the transfer needle is one of the key components in knitting equipment. The transfer needle is a key loop-forming part in knitting equipment, mainly used to transfer loops between different needles during the knitting process. The accuracy of the transfer needle hook size directly affects the quality of the fabric and production efficiency. As the textile industry's demand for high-quality fabrics increases, the manufacturing precision requirements for transfer needles are also getting higher and higher.
[0003] Currently, the industry generally uses traditional machining methods to manufacture transfer needles. Due to problems such as error accumulation and equipment wear during the processing, manual inspection and repair are often used.

[0008] Preferably, the outer wall of the second transmission block is slidably connected to the inner wall of the first connecting block, and the second transmission block is cylindrical in shape.
[0009] Preferably, the mounting assembly includes a mounting block one, the outer wall of which is fixedly connected to the outer wall of a connecting block one, the inner wall of a connecting block two is fixedly connected to a mounting block two, the outer wall of the mounting block two is disposed on the outer wall of the mounting block one, the outer wall of the mounting block two is disposed on the outer wall of the connecting block one, and the lower surface of the mounting block one is slidably connected to the upper surface of the base.
[0010] Preferably, a slider is fixedly connected to the lower surface of the movable block, a groove is provided inside the base, the outer wall of the slider is slidably connected to the inside of the base through the groove, and the lower surface of the movable block is slidably connected to the upper surface of the base.
[0011] Preferably, a slider two is fixedly connected to the lower surface of the connecting block one, the upper surface of the slider two is fixedly connected to the lower surface of the mounting block one, a sliding groove two is provided inside the base, and the outer wall of the slider two is slidably connected to the inside of the base through the slider two.
[0012] Preferably, a positioning block is fixedly connected to the outer wall of the first connecting block, a positioning block is fixedly connected to the outer wall of the second connecting block, a pressing block is rotatably connected to the outer wall of the first positioning block, a rotating shaft is fixedly connected to the inner wall of the pressing block, and a pull arm is rotatably connected to the outer wall of the rotating shaft.
[0013] Preferably, the second positioning block has a locking block inside, the outer wall of the locking block is rotatably connected to the second pull arm, the second pull arm has a return spring inside, and the outer wall of the return spring is located inside the first pull arm.
[0014] Preferably, the second connecting block is made of silicone rubber.
[0015] Working Principle: The hydraulic cylinder drives the moving block to slide, which in turn moves transmission block one left and right. Then, transmission column one moves synchronously under the drive of transmission block one, causing the rotating block to rotate under the drive of transmission column one. Subsequently, transmission column one moves under the counter-push of the rotating block, and then transmission block one moves synchronously under the drive of transmission column one. Next, transmission column two moves along a predetermined trajectory under the drive of the rotating block. At this time, connecting block one moves back and forth under the drive of transmission block two, squeezing mounting block two between the upper and lower mounting blocks one on the surface of connecting block one. Mounting block two is made of silicone rubber, which is elastic, allowing it to be held between mounting blocks one, thus connecting connecting block one and connecting block two. Connecting block two then moves synchronously under the drive of connecting block one, controlling the opening and closing of connecting block two and restricting the probe to be tested to the center position of the two connecting blocks two. Connecting block two is made of silicone rubber, which has elasticity and deformation recovery capabilities. When connecting block two and the probe... Upon contact, it can produce deformation corresponding to the shape of the object's surface, and can return to its original shape after the external force is removed. It can be used multiple times, saving measurement costs. Silicone rubber has tensile strength and tear strength, so it is not easily damaged when the connecting block is subjected to external impact, further ensuring the smooth progress of the detection process. Secondly, silicone rubber has sensor compatibility. It can be integrated with pressure sensors without affecting the performance of the pressure sensors or interfering with the sensor's signal transmission. Silicone rubber has high and low temperature resistance, is resistant to ozonolysis and chemical corrosion, and has electrical insulation and waterproof properties. This allows the connecting block to be used in a variety of complex environments. At the same time, silicone rubber has biocompatibility and is non-irritating and non-sensitizing to human tissues, avoiding harm to maintenance personnel. This can achieve the stability and constant position of the shift needle in the detection and subsequent adjustment process, preventing adjustment deviations caused by the shift needle shaking, reducing the risk of accidental damage to the shift needle, and improving the accuracy and safety of detection and adjustment.
[0016] By pressing the transfer needle with connecting block two, connecting block two wraps around the outside of the transfer needle. Since connecting block two has a certain degree of elasticity, it can adapt to the contour of different models of transfer needles. During this process, the pressure sensor detects the pressure change of connecting block two in real time and compares the collected data with the preset data of the standard model of transfer needle. If there is a deviation between the two sets of data, the robotic arm is started. The robotic arm is equipped with a cutter head and corrects the size of the corresponding area of the transfer needle by cutting or other methods. The operation continues until the data fed back by the pressure sensor matches the standard data. This achieves real-time monitoring of the size of the transfer needle hook and automatic adjustment. The consistency of the size of the same model of transfer needle is guaranteed, the labor input is reduced, the production efficiency is improved, and the product quality is stable.
[0017] By rotating the pressing block, the pressing block drives the rotating shaft to rotate synchronously. During the rotation of the shaft, the first pull arm rotates under its influence, which causes the return spring to undergo elastic deformation due to the pull of the first pull arm. Under the push of the return spring's elastic force, the second pull arm begins to move, causing the locking block to disengage from the second positioning block. At this time, the second connecting block is pulled outward to remove the second mounting block from the limit of the first mounting block, further realizing the separation of the first connecting block and the second connecting block. This allows users to quickly replace damaged or aged second connecting blocks, and also enables regular inspection of the status of the pressure sensor embedded inside the second connecting block.
[0018] This invention provides a device for controlling the consistency of needle hook size in a transfer needle. It has the following beneficial effects: 1. This invention uses connecting block two to compress the transfer needle. At this time, connecting block two wraps around the outside of the transfer needle. Since connecting block two has a certain elasticity, it can adapt to the contour of different models of transfer needles. During this process, the pressure sensor detects the pressure change of connecting block two in real time, thereby achieving real-time monitoring of the transfer needle hook size and automatic adjustment. The consistency of the size of the same model of transfer needle is guaranteed, the labor input is reduced, the production efficiency is improved, and the product quality is stable.
[0019] 2. This invention drives the moving block to slide by activating the hydraulic cylinder. Then, the moving block drives the transmission block to move left and right. Subsequently, the transmission column moves synchronously under the drive of the transmission block, and the rotating block rotates under the drive of the transmission column. This achieves the stability and constant position of the shifting needle in the detection and subsequent adjustment process, prevents deviations in adjustment caused by the shaking of the shifting needle, reduces the risk of accidental damage to the shifting needle, and improves the accuracy and safety of detection and adjustment.
[0020] 3. This invention rotates the pressing block, which then drives the rotating shaft to rotate synchronously. During the rotation of the shaft, the first pull arm rotates under its influence, causing the return spring to undergo elastic deformation due to the pull of the first pull arm. This allows users to quickly replace the damaged or aged second connecting block, and also enables them to periodically check the status of the pressure sensor embedded inside the second connecting block.

[0023] 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 some embodiments of the present invention, and not all embodiments. 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.
[0024] Please see the appendix Figure 1 - Appendix Figure 3This invention provides a device for controlling the consistency of the size of a transfer needle hook, including a base 1, a hydraulic cylinder 2 fixedly connected to the upper surface of the base 1, a moving block 3 connected to the output end of the hydraulic cylinder 2, a transmission block 5 slidably connected to the inner wall of the moving block 3, a transmission column 4 fixedly connected to the upper surface of the transmission block 5, a rotating assembly 6 provided on the upper surface of the base 1, the transmission column 4 connected to the base 1, a transmission assembly 7 connected to the rotating assembly 6, a connecting block 8 slidably connected to the upper surface of the base 1, a transmission assembly 7 connected to the connecting block 8, a connecting block 9 provided on the outer wall of the connecting block 8, a mounting assembly 10 provided on the outer wall of the connecting block 8, a pressure sensor 11 fixedly connected inside the connecting block 9, and a robotic arm 24 fixedly connected to the upper surface of the base 1. Specifically, by activating hydraulic cylinder 2, the moving block 3 slides on the upper surface of base 1. Then, the moving block 3 drives transmission block 5 to move left and right. Since transmission column 4 and transmission block 5 are fixedly connected, transmission column 4 moves synchronously under the drive of transmission block 5. Consequently, rotating component 6 rotates under the drive of transmission column 4. The moving block 3 has a groove inside to limit the displacement range of transmission column 4 and transmission block 5. Then, transmission column 4 moves along the groove inside the moving block 3 under the counter-push of rotating component 6. Subsequently, transmission block 5 moves synchronously under the drive of transmission column 4. The connecting block 8 has a groove inside to limit the displacement range of transmission component 7. Then, transmission component 7 moves along a predetermined trajectory under the drive of rotating component 6. At this time, connecting block 8 moves back and forth under the drive of transmission component 7. Mounting component 10 is used to confine connecting block 9 inside connecting block 8. Since connecting block 8 and connecting block 9 are connected through mounting component 10, connecting block 9 moves back and forth under the drive of connecting component 7. Driven by block 8, the system moves synchronously, thereby controlling the opening and closing of connecting block 9 and restricting the needle hook body 25 of the needle to be moved to the center position of connecting blocks 9 on both sides. This ensures the stability and position of the needle during detection and subsequent adjustment, preventing the needle from shaking and causing adjustment errors or damage. By squeezing the needle through connecting block 9, the needle is wrapped around its outer side. Connecting block 9 deforms according to different needle models, and pressure sensor 11 detects the pressure change of connecting block 9 and compares the data with the standard needle model data. If there is an error between the two data, the robotic arm 24 is activated. The robotic arm 24 is equipped with a cutting head (existing technology, not described in detail). The cutting head corrects the size of the corresponding area until the data detected by pressure sensor 11 matches the standard data. This achieves real-time monitoring and automatic adjustment of the needle hook size, improving the consistency of the size of the same needle model.
[0025] See appendix Figure 1 and attached Figure 2 The rotating assembly 6 includes a rotating shaft 61, the lower surface of which is fixedly connected to the upper surface of the base 1, and a rotating block 62 is rotatably connected to the outer wall of the rotating shaft 61. The outer wall of the transmission column 4 is rotatably connected to the inner wall of the rotating block 62. Specifically, the rotating block 62 rotates under the drive of the transmission column 4, wherein the rotating shaft 61 provides the rotation fulcrum for the rotation of the rotating block 62.
[0026] See appendix Figure 2 and attached Figure 6 The transmission assembly 7 includes a second transmission column 71, the outer wall of which is rotatably connected to the inner wall of the rotating block 62, and the lower surface of the second transmission column 71 is fixedly connected to the second transmission block 72. Specifically, the rotating block 62 is used to drive the transmission column 71 to move, while the transmission column 71 is used to drive the transmission block 72 to move inside the connecting block 8, and the transmission block 72 is used to drive the connecting block 8 to move.
[0027] See appendix Figure 6 The outer wall of transmission block 2 72 is slidably connected to the inner wall of connecting block 1 8, and the shape of transmission block 2 72 is cylindrical; Specifically, the connecting block 8 has a groove inside, and the cylindrical shape of the transmission block 72 allows it to slide within the groove.
[0028] See appendix Figure 1 and attached Figure 4 The mounting component 10 includes mounting block 101, the outer wall of mounting block 101 is fixedly connected to the outer wall of connecting block 18, the inner wall of connecting block 29 is fixedly connected to mounting block 202, the outer wall of mounting block 202 is disposed on the outer wall of mounting block 101, the outer wall of mounting block 202 is disposed on the outer wall of connecting block 18, and the lower surface of mounting block 101 is slidably connected to the upper surface of base 1. Specifically, by squeezing the second mounting block 102 between the upper and lower mounting blocks 101 on the surface of the first connecting block 8, the second mounting block 102 and the second connecting block 9 are made of the same material, silicone rubber. Silicone rubber itself is elastic, which allows the second mounting block 102 to be stuck between the first mounting blocks 101, thereby connecting the first connecting block 8 and the second connecting block 9.
[0029] See appendix Figure 1 and attached Figure 5 The lower surface of the movable block 3 is fixedly connected to a slider 12, and the interior of the base 1 is provided with a groove 13. The outer wall of the slider 12 is slidably connected to the interior of the base 1 through the groove 13, and the lower surface of the movable block 3 is slidably connected to the upper surface of the base 1. Specifically, since the movable block 3 is fixedly connected to the slider 12, the slider 12 slides along the slide groove 13 inside the base 1 under the drive of the movable block 3. At the same time, the slider 12 and the slide groove 13 cooperate to restrict the displacement direction and range of the movable block 3.
[0030] See appendix Figure 1 and attached Figure 7 The lower surface of the connecting block 18 is fixedly connected to the slider 2 14, the upper surface of the slider 2 14 is fixedly connected to the lower surface of the mounting block 101, the interior of the base 1 is provided with a sliding groove 2 15, and the outer wall of the slider 2 14 is slidably connected to the interior of the base 1 through the slider 2 14. Specifically, since the connecting block 18 is fixedly connected to the slider 2 14, the slider 2 14 slides inside the base 1 through the sliding groove 2 15 under the drive of the connecting block 18. At the same time, the slider 2 14 and the sliding groove 2 15 cooperate to restrict the displacement direction and range of the connecting block 18.
[0031] See appendix Figure 6 - Appendix Figure 8 A positioning block 16 is fixedly connected to the outer wall of connecting block 18, and a positioning block 27 is fixedly connected to the outer wall of connecting block 29. A pressing block 18 is rotatably connected to the outer wall of positioning block 16, and a rotating shaft 19 is fixedly connected to the inner wall of pressing block 18. A pull arm 20 is rotatably connected to the outer wall of rotating shaft 19. A locking block 23 is provided inside positioning block 27, and a pull arm 21 is rotatably connected to the outer wall of locking block 23. A return spring 22 is provided inside pull arm 21, and the outer wall of return spring 22 is located inside pull arm 20. Specifically, by rotating the pressing block 18 to make it rotate around the positioning block 16, the rotating shaft 19 rotates under the drive of the pressing block 18, and then the pull arm 20 rotates around the rotating shaft 19 under the drive of the rotating shaft 19. Then, the return spring 22 undergoes elastic deformation under the drive of the pull arm 20. At this time, the pull arm 21 moves under the push of the return spring 22. Since the locking block 23 is fixedly connected to the pull arm 21, the locking block 23 disengages from the inside of the positioning block 17 under the drive of the pull arm 21. At this time, the external pulling connecting block 29 removes the mounting block 102 from the restriction of the mounting block 101, and then the connecting block 8 separates from the connecting block 29. Finally, the purpose of controlling the quick installation and disassembly of the connecting block 29 is achieved, so as to facilitate the user to replace the damaged or aged connecting block 29 and regularly check the condition of the pressure sensor 11 embedded inside the connecting block 29.
[0032] See appendix Figure 7 Connector 29 is made of silicone rubber; Specifically, connecting block 9 is made of silicone rubber. Silicone rubber is a rubber with a silicon-oxygen Si-O bond main chain structure. Silicone rubber has elasticity and deformation recovery ability. When connecting block 9 comes into contact with the moving needle, it can produce deformation corresponding to the shape of the object surface. After the external force is removed, it can return to its original shape, ensuring the accuracy of each measurement. It can be reused multiple times, reducing measurement costs. Silicone rubber also has tensile strength and tear strength, so it is not easily damaged even when subjected to a certain degree of external force during the measurement process, ensuring the smooth progress of the measurement process. Secondly, silicone rubber has sensor compatibility and can be integrated with pressure sensor 11. It will not affect the performance of pressure sensor 11, nor will it interfere with the sensor's signal transmission, which is beneficial for obtaining measurement data. Silicone rubber has high and low temperature resistance and can maintain stable physical properties in a temperature range of -60℃ to 250℃. It is also resistant to ozonolysis and chemical corrosion. Except for strong alkalis and hydrofluoric acid, its chemical properties are stable. It also has electrical insulation and waterproof properties, which allows connecting block 2 9 to be used in a variety of complex environments. At the same time, silicone rubber has biocompatibility. Silicone rubber is non-toxic, odorless, physiologically inert, will not cause blood clotting, and has no irritation or sensitization to human tissues, which can ensure the safety and reliability of the detection and replacement process.
