Description

Technical Field

[0001] This invention relates to the field of milling device technology, and in particular to a contour milling device for knitting needle preparation. Background Technology

[0002] Knitting needles are loop-forming components in knitting machinery. They move regularly under the drive of the knitting machine to complete the knitting work. The quality of knitting needles directly affects the quality of knitted fabrics and production efficiency. Common knitting needles are usually made of slender metal rods through multiple processes such as stamping, milling, and polishing. They have a fine structure and require extremely high dimensional accuracy and surface smoothness.

[0003] In the manufacturing process of knitting needles, precise milling is required at specific locations on the needle bar to facilitate the installation of subsequent components or to achieve specific knitting functions. Therefore, profile milling equipment for knitting needle preparation is particularly important. This type of equipment typically includes feeding, conveying, processing, and unloading processes. It automates the transport of blank knitting needles to the processing station, where milling cutters cut the surface of the needles according to a preset trajectory.

[0004] Existing milling equipment for knitting needle preparation typically uses a roller-type feeding structure. This involves a motor driving a roller with several grooves to rotate, allowing knitting needles to fall from the hopper into the grooves for individual separation and transport. However, due to the wide variety of knitting needle specifications and variations in length, width, and thickness, the fixed roller grooves cannot accommodate all sizes, leading to jamming or multiple needles falling simultaneously. To address this issue, current technologies usually involve replacing the entire roller or fixing different sized limit strips to the roller surface with bolts. However, replacing the entire roller is costly in terms of spare parts, and the roller's large size and weight make disassembly and assembly time-consuming and labor-intensive. Replacing the feeding blocks with bolts is also cumbersome and time-consuming, as there are numerous feeding blocks distributed around the roller's circumference. Operators must loosen and remove the bolts one by one, then tighten them again after replacement, resulting in excessive downtime during production changes and significantly reducing production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a contour milling device for knitting needle preparation, which solves the problem that the existing technology has a cumbersome and time-consuming operation of changing the feeding component when processing knitting needles of different sizes, resulting in low equipment turnover efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A contour milling device for preparing knitting needles includes a processing frame, a feeding mechanism on the top left side of the processing frame, a feeding mechanism on the inner side of the processing frame, a discharging mechanism on the right side of the processing frame, and a processing component at the top center of the processing frame. The feeding mechanism includes a fixed frame, which is fixedly connected to the left side of the outer wall of the processing frame. An outer cylinder is fixedly connected to the inner side of the fixed frame, and a roller is rotatably connected to the inner side of the outer cylinder. A motor is fixedly connected to the front side of the fixed frame, and the output end of the motor passes through the fixed frame and is fixedly connected to the roller. Multiple feeding blocks are installed at equal intervals on the outer side of the roller. Hollow rings are fixedly connected to the front and rear ends of the roller. A turntable is rotatably connected to the inner side of the hollow ring. Multiple curved grooves are equidistantly opened on the outer side of the turntable. Insertion posts are slidably connected to the inner side of the curved grooves. Limit blocks are rotatably connected to the outer side of the insertion posts through the hollow rings. Locking components are provided on the opposite sides of the two turntables.

[0007] The above technical solution utilizes a locking component in conjunction with a turntable and plug-in pins to control the extension and retraction of the limit block, enabling rapid unlocking and replacement of the feeding block. The motor drives the roller to rotate, which in turn assists the feeding block in completing the orderly feeding of individual knitting needles.

[0008] Preferably, the feeding mechanism includes a conveyor belt disposed on the inner side of the processing frame. Multiple U-shaped plates are fixedly connected at equal intervals to the outer side of the conveyor belt. Receiving blocks are slidably connected to the front and rear sides of the inner sides of each U-shaped plate. A connecting block is fixedly connected to the outer side of each receiving block. Guide rails are provided on the front and rear sides of the inner side of the processing frame. The connecting block is slidably connected to the inner side of the guide rail. A hollow plate is fixedly connected to the center of the bottom inner side of the processing frame. A bidirectional lead screw is rotatably connected to the front and rear sides of the inner side of the hollow plate. The left end of the bidirectional lead screw penetrates the hollow plate. Slider blocks are threaded to the left and right sides of the outer wall of the bidirectional lead screw. A connecting rod is rotatably connected to the inner side of each slider. The connecting rod is rotatably connected to the guide rail.

[0009] Through the above technical solution, the rotating bidirectional lead screw drives the slider and connecting rod to move, which in turn drives the guide rail and take-up block to slide and adjust within the U-shaped plate, thereby achieving adaptive clamping and conveying position adjustment for knitting needles of different lengths.

[0010] Preferably, the discharge mechanism includes a baffle, a connecting plate, and a transmission belt. The baffle is fixedly connected to the right side of the processing frame. An outer frame is fixedly connected to the lower middle part of the right side of the processing frame. A receiving hopper is fixedly connected to the top inner side of the outer frame. Movable plates are rotatably connected to the bottom left and right sides of the receiving hopper. The front and rear sides of the two movable plates are rotatably connected to the corresponding connecting plates. A back plate is fixedly connected to the right wall of the right movable plate. Rotating columns are rotatably connected to the front, rear, left, and right sides of the interior of the processing frame. A pulley is fixedly connected to one end of each rotating column. The left pulley is connected to the right pulley via a transmission belt. A movable rod is rotatably connected to the outer side of the transmission belt. The movable rod is slidably connected to the inner side of the back plate. A drive assembly is provided on the inner side of the outer frame.

[0011] The above technical solution utilizes a drive assembly in conjunction with a belt pulley transmission system to drive the movable rod to move, which in turn drives the movable plate to deflect via the back plate, thereby enabling convenient adjustment of the needle feeding angle and position.

[0012] Preferably, the processing assembly includes a bracket, which is fixedly connected to the middle of the outer side of the processing frame. Hydraulic rods are fixedly connected to the front and rear sides of the top of the bracket. The bottom end of the hydraulic rod passes through the bracket and is fixedly connected to a support plate. A milling cutter is fixedly connected to the front bottom of the support plate.

[0013] The above technical solution utilizes a hydraulic rod to drive the support plate and milling cutter to lift and lower, thereby automating the milling process on the knitting needles delivered to the workstation.

[0014] Preferably, the processing assembly further includes two guide rods, which are respectively fixedly connected to the top left and right sides of the support plate. A top plate is slidably connected to the outer side of the guide rods, and a pressure plate is fixedly connected to the bottom of the top plate. The bottom of the pressure plate passes through the support plate. A spring is provided at the bottom of the outer side of the guide rods, and the upper and lower ends of the spring are fixedly connected to the top plate and the support plate, respectively.

[0015] Through the above technical solution, during the pressing down of the support plate, the elastic extension and contraction of the pressure plate and spring are used to press the knitting needle tightly, ensuring that the knitting needle position is stable during the milling process.

[0016] Preferably, the locking assembly includes multiple levers, which are respectively fixedly connected to the left and right sides of the outer wall of the corresponding turntable. The outer wall of the hollow ring is provided with a sliding groove on both the left and right sides. The outer side of the lever passes through the sliding groove and is fixedly connected with a toothed ring. The outer side of the hollow ring is fixedly connected with a toothed groove, and the toothed ring and the toothed groove are engaged.

[0017] The above technical solution utilizes the meshing and disengagement of the toothed ring and toothed groove to lock and unlock the rotation angle of the turntable, facilitating manual operation of the turntable for adjustment.

[0018] Preferably, the feeding mechanism further includes a feeding port, which is located at the top of the outer cylinder. A feeding hopper is fixedly connected to the top of the fixed frame, and a discharge port is located at the bottom of the outer cylinder.

[0019] The above technical solution, in conjunction with the feed hopper and discharge port, constructs a channel for the knitting needles to enter and exit, ensuring that the knitting needles smoothly enter the rollers and accurately fall into the feeding mechanism.

[0020] Preferably, the feeding mechanism further includes a knob, which is fixedly connected to the left side of the bidirectional lead screw, and the inner side of the hollow plate is slidably connected to the slider.

[0021] The above technical solution allows operators to manually rotate the bidirectional lead screw to precisely fine-tune the receiving position of the feeding mechanism.

[0022] Preferably, the feeding mechanism further includes multiple guide blocks, which are respectively fixedly connected to the left and right sides of the bottom of the corresponding guide rail. The bottom left and right sides of the processing frame are provided with through slots, and the outer side of the guide block is slidably connected to the through slot.

[0023] The above technical solution utilizes the sliding fit between the guide block and the through groove to limit and guide the movement of the guide rail, thereby improving the smoothness of the adjustment process.

[0024] Preferably, the drive assembly includes a second motor, which is fixedly connected to the front side of the outer frame. The output end of the second motor passes through the outer frame and is fixedly connected to a transmission rod. Gear 1 is fixedly connected to both the front and rear sides of the outer wall of the transmission rod. Gear 2 is fixedly connected to the outer walls of the two rotating columns on the right side. Gear 2 meshes with gear 1.

[0025] Through the above technical solution, the second motor transmits power through gear meshing to drive the rotating column to rotate, thereby driving the pulley to adjust the discharge position.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention uses the axial pulling of the toothed ring to disengage from the limit and rotate it. The turntable is driven to rotate by the lever, and then the curved groove and the plug-in column are used to simultaneously drive all the limit blocks into the hollow ring. When different sizes of knitting needles need to be processed, there is no need to use tools to disassemble the bolts one by one. All the feeding blocks can be released and quickly replaced with one click, which shortens the downtime adjustment time when the equipment changes production, improves production efficiency and adaptability to processing knitting needles of multiple specifications.

[0027] 2. This invention drives a bidirectional lead screw to rotate via a knob, which in turn moves a slider. The slider then moves a guide rail via a connecting rod, enabling the take-up block to slide and adjust within a U-shaped plate. This allows the support position of the take-up block to be adjusted according to the length of the knitting needle, ensuring that knitting needles of different lengths can be stably clamped during transport. Furthermore, by changing the position of the take-up block, the axial position of the knitting needle relative to the processing components can be precisely adjusted, ensuring processing accuracy and meeting diverse processing requirements.

[0028] 3. This invention uses a motor-driven gear set and belt pulley transmission system to drive the movable rod to slide inside the back plate, thereby controlling the deflection angle of the movable plates on both sides of the bottom of the discharge hopper, automatically adjusting the guide path of the falling needles, and conveniently changing the drop point of the needles according to the position of the collection container or the needs of subsequent processes, thus improving the automation level of the equipment and the convenience of material collection.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 The present invention will be further described in detail below.

[0032] The present invention provides a contour milling device for knitting needle preparation, including a processing frame 1, a feeding mechanism 2 is provided on the top left side of the processing frame 1, a feeding mechanism 3 is provided on the inner side of the processing frame 1, a discharging mechanism 4 is provided on the right side of the processing frame 1, and a processing component 5 is provided at the top center of the processing frame 1. The feeding mechanism 2 includes a fixed frame 21, which is fixedly connected to the left side of the outer wall of the processing frame 1. An outer cylinder 22 is fixedly connected to the inner side of the fixed frame 21, and a roller 23 is rotatably connected to the inner side of the outer cylinder 22. A motor 214 is fixedly connected to the front side of the fixed frame 21. The output end of the motor 214 passes through the fixed frame 21 and is fixedly connected to the roller 23. The motor 214 can drive the roller 23 to rotate. Multiple feeding blocks 24 are equidistantly installed on the outer side of the roller 23. The feeding blocks 24 are used to accommodate knitting needles. Hollow rings 25 are fixedly connected to the front and rear ends of the roller 23. A turntable 26 is rotatably connected to the inner side of the hollow rings 25. Multiple curved grooves 27 are equidistantly opened on the outer side of the turntable 26. Insertion pins 28 are slidably connected to the inner side of the curved grooves 27. When the turntable 26 rotates, the insertion pins 28 can be pushed to rotate through the curved grooves 27. The outer side of the insertion pins 28 passes through the hollow rings 25 and rotates. A locking component 29 is provided on the opposite side of the two turntables 26 connected to the limiting block 210. The locking component 29 includes multiple levers 291, which are fixedly connected to the left and right sides of the outer wall of the corresponding turntable 26. The left and right sides of the outer wall of the hollow ring 25 are provided with sliding grooves 292. The outer side of the lever 291 passes through the sliding groove 292 and is fixedly connected to a toothed ring 293. The outer side of the hollow ring 25 is fixedly connected to a toothed groove 294. The toothed ring 293 and the toothed groove 294 are meshed and connected. The toothed groove 294 can limit the toothed ring 293. The feeding mechanism 2 also includes a feed inlet 211, which is opened at the top of the outer cylinder 22. The top of the fixed frame 21 is fixedly connected to a feed hopper 212. The knitting needles in the feed hopper 212 can enter the feeding block 24 through the feed inlet 211. The bottom of the outer cylinder 22 is provided with a discharge outlet 213, from which the knitting needles can fall. Specifically, before processing knitting needles of different specifications and sizes, the equipment needs to be adjusted. The toothed rings 293 at both ends are pulled outwards, causing them to move axially and disengage from the toothed grooves 294, thus releasing the restriction on the rotation angle of the toothed rings 293. Then, the toothed rings 293 are rotated, driving the internal turntable 26 to rotate via the fixed lever 291. As the turntable 26 rotates, it presses against the insertion post 28 through the curved groove 27, forcing the insertion post 28 to move radially. The displacement of the insertion post 28 causes the limiting block 210 to retract into the inner space of the hollow ring 25, causing the limiting block 210 to separate from the feeding block 24 on the outer side of the roller 23, thus releasing the restriction on the feeding block 210. The fixed constraint of 4 is then removed, and the original feeding block 24 is replaced with a new feeding block 24 adapted to the target needle size. This completes the feeding preparation work for needles of different sizes. When the feeding mechanism 2 starts working, the needles with the head facing the same direction are placed into the feeding hopper 212. Under the action of gravity, the needles slide into the feeding port 211 through the feeding hopper 212. At the same time, the motor 214 drives the roller 23 to rotate continuously. The needles fall into the corresponding receiving slots of the feeding block 24 in sequence. The slot size of the feeding block 24 is used to ensure that a single slot can accommodate a single needle. As the roller 23 rotates, the needles fall vertically into the feeding mechanism 3 below through the discharge port 213 at the bottom of the outer cylinder 22 and enter the subsequent conveying stage.

[0033] The feeding mechanism 3 includes a conveyor belt 31, which is disposed inside the processing frame 1. Multiple U-shaped plates 32 are fixedly connected at equal intervals to the outer side of the conveyor belt 31. Receiving blocks 33 are slidably connected to the front and rear sides of the interior of each U-shaped plate 32. Knitting needles falling from the discharge port 213 can enter the receiving blocks 33. Connecting blocks 34 are fixedly connected to the outer side of each receiving block 33. Guide rails 35 are provided on both the front and rear sides of the interior of the processing frame 1. Connecting blocks 34 are slidably connected to the inner sides of the guide rails 35. A hollow plate 36 is fixedly connected to the center of the bottom end of the interior of the processing frame 1. Double... The left end of the double-acting screw 37 passes through the hollow plate 36. The left and right sides of the outer wall of the double-acting screw 37 are threaded with sliders 38. When the double-acting screw 37 rotates, the sliders 38 will move accordingly. The inner side of the sliders 38 is rotatably connected to the connecting rod 39. The connecting rod 39 is rotatably connected to the guide rail 35. When the sliders 38 move, the connecting rod 39 can push the guide rail 35 to move. The feeding mechanism 3 also includes a knob 310. The knob 310 makes it convenient for the operator to rotate the double-acting screw 37. The knob 310 is fixedly connected to the left side of the double-acting screw 37. The inner side of the hollow plate 36 is slidably connected to the sliders 38. Specifically, by rotating the knobs 310 located on both sides, the bidirectional lead screw 37 is driven to rotate. Since the slider 38 is restricted inside the hollow plate 36 and cannot rotate with the lead screw, the rotation of the bidirectional lead screw 37 drives the slider 38 to move linearly along the axial direction. The slider 38 pushes the guide rail 35 to move through the connecting rod 39. Since the connecting block 34 at the end of the take-up block 33 is slidably embedded inside the guide rail 35, the movement of the guide rail 35 drives the take-up block 33 to slide in the inner groove of the U-shaped plate 32 through the connecting block 34. By independently adjusting the relative positions of the two take-up blocks 33 in the U-shaped plate 32, the distance between the support points can be changed to adapt to the conveying of knitting needles of different lengths, and the axial position of the knitting needles can be finely adjusted to precisely control the milling part. When the knitting needle falls from the outlet 213 and enters the take-up block 33 after the position is adjusted, the conveyor belt 31 starts to run, driving the U-shaped plate 32 and the knitting needles inside to move synchronously, and conveying the knitting needles to the processing area.

[0034] The discharge mechanism 4 includes a baffle 41, a connecting plate 411, and a transmission belt 48. The baffle 41 is fixedly connected to the right side of the processing frame 1. An outer frame 42 is fixedly connected to the lower middle part of the right side of the processing frame 1. A receiving hopper 43 is fixedly connected to the top inner side of the outer frame 42. Movable plates 44 are rotatably connected to the left and right sides of the bottom of the receiving hopper 43. The front and rear sides of the two movable plates 44 are rotatably connected to the corresponding connecting plates 411. The movable plates 44 can swing at the bottom of the receiving hopper 43, and the two movable plates 44 are connected through the connecting plate 411, thus swinging synchronously. A back plate 45 is fixedly connected to the right wall of the right movable plate 44. Rotating columns 46 are rotatably connected to the front, rear, left, and right sides of the interior of the processing frame 1. A pulley 47 is fixedly connected to one end of each rotating column 46. The left pulley 47 is connected to the right pulley 47 through the transmission belt 48. A movable rod 410 is rotatably connected to the outer side of the 8. The movable rod 410 is slidably connected to the inner side of the back plate 45. When the transmission belt 48 is running, it drives the movable rod 410 to move, thereby causing the back plate 45 and the movable plate 44 to swing. A drive assembly 49 is provided on the inner side of the outer frame 42. The drive assembly 49 includes a second motor 491. The second motor 491 is fixedly connected to the front side of the outer frame 42. The output end of the second motor 491 passes through the outer frame 42 and is fixedly connected to a transmission rod 492. Gear 493 is fixedly connected to both the front and rear sides of the outer wall of the transmission rod 492. The second motor 491 drives the first gear 493 to rotate through the transmission rod 492. Gear 494 is fixedly connected to the outer walls of the two rotating columns 46 on the right side. Gear 494 meshes with the first gear 493. When the first gear 493 rotates, the second gear 494 will drive the right rotating column 46 to rotate. Specifically, after processing, the knitting needles continue to move to the right until they detach from the connecting block 34. After being blocked by the baffle 41, they fall into the receiving hopper 43 under the action of gravity. The knitting needles that fall into the receiving hopper 43 slide out through the bottom and pass through the channel formed by the movable plates 44 on both sides into the collection container. When it is necessary to adjust the dropping position of the knitting needles, the second motor 491 is started. The second motor 491 drives the first gear 493 to rotate through the transmission rod 492. Since the second gear 494 meshes with the first gear 493, it drives the right rotating column 46 and the right pulley 47 to rotate and drives the transmission belt 48 to run. The movable rod 410 fixed on the transmission belt 48 is displaced accordingly. The movable rod 410 slides in the back plate 45 on the side of the movable plate 44, causing the two movable plates 44 to deflect around the axis, thereby changing the discharge angle and realizing the adjustment of the dropping point of the knitting needles.

[0035] The processing component 5 includes a bracket 51, which is fixedly connected to the middle of the outer side of the processing frame 1. Hydraulic rods 52 are fixedly connected to the front and rear sides of the top of the bracket 51. The bottom end of the hydraulic rod 52 passes through the bracket 51 and is fixedly connected to a support plate 53. A milling cutter 54 is fixedly connected to the bottom front side of the support plate 53. The processing component 5 also includes two guide rods 55, which are fixedly connected to the left and right sides of the top of the support plate 53 respectively. A top plate 56 is slidably connected to the outer side of the guide rod 55. A pressure plate 57 is fixedly connected to the bottom of the top plate 56. The bottom of the pressure plate 57 passes through the support plate 53. A spring 58 is provided at the bottom of the outer side of the guide rod 55. The upper and lower ends of the spring 58 are fixedly connected to the top plate 56 and the support plate 53 respectively. Specifically, when the knitting needle moves to the predetermined processing position, the hydraulic rod 52 extends and drives the support plate 53 to feed vertically downward. The support plate 53 drives the bottom milling cutter 54 and the pressure plate 57 to move down synchronously. During the downward pressing process, the bottom surface of the pressure plate 57 contacts the surface of the knitting needle first. As the support plate 53 continues to drive the milling cutter 54 to press down and cut into the knitting needle for milling, the obstructed pressure plate 57 causes the top plate 56 to move upward relative to the continuing downward support plate 53, thereby stretching the spring 58 connected between the two. The elastic restoring force generated by the spring 58 makes the pressure plate 57 continuously press the knitting needle, ensuring that the knitting needle remains stable during the cutting process of the milling cutter 54 and preventing displacement or shaking.

[0036] The feeding mechanism 3 also includes multiple guide blocks 311, which are fixedly connected to the bottom left and right sides of the corresponding guide rails 35. The bottom left and right sides of the processing frame 1 are provided with through slots 312, and the outer side of the guide block 311 is slidably connected to the through slot 312. Specifically, the guide block 311 at the bottom of the guide rail 35 is limited by the through groove 312, so that the guide rail 35 will not deviate when moving, thus ensuring the accuracy of the movement.

[0037] Working principle: When processing knitting needles of different sizes, pull the toothed rings 293 on both sides to disengage them from the toothed grooves 294, thereby releasing the limiting effect on the toothed rings 293. Then, rotate the toothed rings 293. The toothed rings 293, via the lever 291, drive the turntable 26 to rotate. When the turntable 26 rotates, it pushes the insertion post 28 to move through the curved groove 27. As the insertion post 28 moves, it causes the limiting block 210 to retract into the hollow ring 25, thereby releasing the limiting effect on the feeding block 24 on the outer side of the roller 23, allowing the feeding to proceed. Block 24 can be removed and replaced. By replacing the feeding block 24, it is possible to feed knitting needles of different sizes. When feeding using the feeding mechanism 2, knitting needles with the same orientation are placed into the feeding hopper 212. The knitting needles will then enter the feeding port 211 through the feeding hopper 212. At this time, the motor 214 drives the roller 23 to rotate, and the knitting needles will fall into the corresponding feeding block 24. Each feeding block 24 can only hold a single knitting needle. The knitting needles can then fall into the feeding mechanism 3 through the discharge port 213 at the bottom of the outer cylinder 22 for subsequent feeding. Furthermore, by rotating the knobs 310 on both sides, the knobs 310 will drive the bidirectional lead screw 37 to rotate. Since the slider 38 can only slide within the hollow plate 36, the slider 38 will move along with the bidirectional lead screw 37 when it rotates, and can push the guide rail 35 to move through the connecting rod 39. Since the connecting block 34 at one end of the take-up block 33 is installed inside the guide rail 35, the take-up block 33 can slide in the U-shaped plate 32 through the connecting block 34 when the guide rail 35 moves. By adjusting the position of the take-up blocks 33 on both sides in the U-shaped plate 32, not only can the milling groove position of the knitting needle be adjusted, but knitting needles of different lengths can also be conveyed. When the knitting needle falls from the outlet 213, it will fall into the take-up block 33. At this time, the conveyor belt 31 will drive the U-shaped plate 32 to move, thereby conveying the knitting needle. When the knitting needle enters the processing position, the hydraulic rod 52 is activated, which drives the support plate 53 to move downward. The support plate 53 will then drive the milling cutter 54 and the pressure plate 57 to move downward simultaneously. When the pressure plate 57 contacts the knitting needle, the support plate 53 continues to drive the milling cutter 54 to press down and mill the knitting needle. Meanwhile, the pressure plate 57 will drive the top plate 56 to move upward relative to the support plate 53, thereby stretching the spring 58, which can keep the position of the knitting needle unchanged during the processing. Finally, when the knitting needle finishes processing and moves to the right, it will detach from the connecting block 34 and be blocked by the baffle 41, then fall into the receiving hopper 43. The knitting needle in the receiving hopper 43 will fall from the bottom and pass through the movable plates 44 on both sides before falling into the collection container. When it is necessary to change the position of the knitting needle, the second motor 491 is started. The second motor 491 will drive the first gear 493 to rotate through the transmission rod 492. Since the second gear 494 meshes with the first gear 493, the second gear 494 will drive the right rotating column 46 to rotate, which in turn drives the right pulley 47 to rotate, driving the transmission belt 48 to rotate. When the transmission belt 48 rotates, it will drive the movable rod 410 to move. The movable rod 410 will then slide in the back plate 45 on one side of the movable plate 44, thereby causing the movable plates 44 on both sides to deflect, so that the position of the knitting needle can be easily adjusted.
