Description

Technical Field

[0001] This application relates to the field of ball production equipment, and in particular to a CNC ball bladder winding machine. Background Technology

[0002] A ball bladder winding machine is a mechanical device used for winding yarn around the bladder (inner lining of a ball). Its function is to evenly wind yarn around the surface of the bladder to form a yarn layer of a certain thickness and strength, ensuring the structural stability and performance of the bladder.

[0003] Traditional ball-winding machines use a clutchless gearbox-type adjustment device to control the ball phase change and frequency. However, this method is noisy, requires high-strength materials, is costly, and prone to failure. The control rollers for the ball phase change are connected to the "clutchless gearbox" via a universal joint, making operation cumbersome.

[0004] To address the aforementioned issues, a ball-load winding machine (publication number CN111659087A) has been disclosed. Its technical solution includes a worktable, a main shaft, a rotating disk, ball-load clamps, and a ball-load transformation mechanism. The main shaft passes through the worktable, and its top is fixedly connected to the rotating disk. The end of the main shaft away from the rotating disk is connected to a transmission mechanism. Several sets of ball-load clamps are distributed circumferentially on the rotating disk. Each ball-load clamp includes a mounting base and a ball-load support claw. The mounting base is mounted on the upper surface of the rotating disk, and one end of each ball-load support claw is rotatably mounted on the mounting base. The machine also includes a clamp adjustment mechanism, comprising an adjusting screw sleeve and an adjusting protrusion. The adjusting screw sleeve is threadedly connected to the rotating disk. Each ball-load support claw has an adjusting protrusion on its side away from the center of the rotating disk. The adjusting protrusion has a structure that is larger at the top and smaller at the bottom, and the adjusting protrusion and the ball-load support claw are an integral structure. The adjustment screw sleeve can be moved up or down by rotating it, thereby causing the bladder support claws of the bladder clamp to close or open, which can be used for bladders of different sizes.

[0005] However, the above method of adapting to different sized bladders requires manual adjustment by rotating the adjusting screw sleeve to close or open the bladder clamp's bladder claws, which is inconvenient and needs improvement. Utility Model Content

[0006] To facilitate the adjustment and placement of ball bladders of different sizes, this application provides a CNC ball bladder winding machine.

[0007] The CNC ball-shaped yarn winding machine provided in this application adopts the following technical solution: A CNC ball-shaped yarn winding machine includes a ball clamp, a rotating frame, a main shaft, a drive mechanism, and an electrical control box. The main shaft extends vertically out of the outside of the electrical control box. The drive mechanism is installed inside the electrical control box and is used to drive the main shaft to rotate. The rotating frame is fixedly installed on the upper end of the main shaft, and the ball clamp is installed on the rotating frame. The rotating frame includes a rotating base, a mounting ring seat, a lifting seat, and multiple vertical rods. The rotating base is horizontally fixedly installed on the upper end of the main shaft. The mounting ring seat is located above the rotating base. The multiple vertical rods are vertically distributed and fixed between the rotating base and the mounting ring seat. The lifting seat is located between the rotating base and the mounting ring seat and is movably inserted through the vertical rods. The bladder clamp includes multiple support arms and multiple connecting rods. The multiple support arms are arranged circumferentially on the lifting seat. The lower end of the support arm is hinged to the lifting seat. The upper end of the connecting rod is connected to the support arm, and the lower end is hinged to the mounting ring seat. A driving component is provided on the rotating base. The output shaft of the driving component is connected to the lifting seat and is used to drive the lifting seat to move up and down.

[0008] By adopting the above technical solution, the ball to be wound is placed on the ball clamp. The drive spindle is controlled by the electrical control box and drive mechanism to drive the rotating frame and the ball clamp to rotate, so that the ball placed on the ball clamp rotates and wounds the yarn. The lifting seat is driven up and down by controlling the drive component. Since the support arm is hinged on the lifting seat, it can be driven to close or open, so as to adapt to different sizes of ball. This makes it easy to operate and adjust the opening size of the ball clamp to adapt to the size of the placed ball. Moreover, there is no need to stop the machine to operate, and the position of the ball can be flexibly adjusted to control the accuracy of the yarn winding position.

[0009] Preferably, it also includes a ball-bladder reversing mechanism, which includes a transmission wheel, a transmission motor, and a transmission assembly. The transmission wheel is rotatably connected to the upper end of the support arm, the transmission motor is installed at the bottom of the lifting seat, and the transmission assembly is disposed between the output shaft of the transmission motor and the transmission wheel.

[0010] By adopting the above technical solution, after the ball bladder is placed on the ball bladder clamp, the ball bladder contacts the transmission wheel. The transmission motor drives the transmission assembly to rotate the transmission wheel, so that during the rotation of the ball bladder, the transmission wheel drives the ball bladder to change direction, thereby making the yarn evenly wound on the ball bladder. In addition, through the connection of the transmission assembly, the transmission motor is installed at the bottom of the lifting plate, which greatly reduces the weight of the support arm, thereby improving the stability of the support arm during rotation and improving the quality of yarn winding on the ball bladder. This prevents the support arm from being unstable and vibrating due to centrifugal force during rotation caused by excessive weight.

[0011] Preferably, the transmission assembly includes a helical gear set, a cover, a transmission rod, and a universal coupling. The output shaft of the transmission motor extends above the lifting seat, and the output shaft of the transmission motor is connected to one end of the universal coupling. The other end of the universal coupling is connected to the transmission rod. The shaft of the transmission wheel extends to the other side of the support arm. One of the helical gears in the helical gear set is coaxially and fixedly connected to the shaft. The transmission rod is coaxially and fixedly connected to the other helical gear. The cover is placed over the helical gear set.

[0012] By adopting the above technical solution, the output shaft of the drive motor is connected to the universal coupling, and then the drive wheel is driven to rotate through the transmission rod and the helical gear set, so that the support arm can rotate. At the same time, the drive motor is installed at the bottom of the lifting seat, and the helical gear set is sealed with a cover, so that the yarn will not get caught on the output shaft of the drive motor during the winding process, which would damage the motor. Furthermore, the gear ratio of the helical gear set can reduce the output speed of the drive motor, thereby making the rotation of the drive wheel more stable.

[0013] Preferably, the drive mechanism includes a drive motor and a pulley assembly. The drive motor is installed inside the electrical control box. The output shaft of the drive motor is connected to the main shaft via the pulley assembly. The main shaft is hollow and has a through-hole conductive slip ring connected to it.

[0014] By adopting the above technical solution, the drive motor drives the main shaft to rotate through the pulley set, and the power connection between the transmission motor and the drive component mounted on the rotating frame is realized through the through-hole conductive slip ring.

[0015] Preferably, it also includes a plurality of auxiliary wheels, which are rotatably connected to the support arm at intervals along the circumferential direction, so that the transmission wheel and the auxiliary wheels are distributed and installed on two adjacent support arms.

[0016] By adopting the above technical solution, the stability of the ball's rotation on the ball clamp is improved by using auxiliary wheels that are arranged adjacent to each other on one side of the transmission wheel support arm.

[0017] Preferably, a mounting bracket is provided on one side of the electrical control box, and a limiting component is provided on the mounting bracket. The limiting component includes a pusher and a limiting block. The pusher is mounted on the mounting bracket, and the limiting block is mounted on the output shaft of the pusher, so that the pusher drives the limiting block to be above the bladder clamp, for a limiting position near the top of the bladder or a clearance position away from the top of the bladder.

[0018] By adopting the above technical solution, when the ball bladder rotates and winds yarn with the ball bladder clamp, it is limited by the limiting block installed on the top of the ball bladder, thereby preventing the ball bladder from jumping and falling off the ball bladder clamp. After the ball bladder has finished winding yarn, the pushing component pushes the limiting block away from the top of the ball bladder, thereby facilitating the picking and placing of the ball bladder on the ball bladder clamp.

[0019] Preferably, the mounting frame is provided with an adjustment component for adjusting the vertical position of the limiting component. The adjustment component includes an adjustment block and a lead screw. The mounting frame includes a mounting rod and two fixed blocks that are horizontally arranged at the upper end of the mounting rod. The lead screw is vertically rotatably connected between the two fixed blocks. The adjustment block is threadedly connected to the lead screw and is movably inserted through the mounting rod. The pusher is mounted on the adjustment block.

[0020] By adopting the above technical solution, the position of the adjusting block threaded on the lead screw can be adjusted by rotating the lead screw, thereby adjusting the position of the limiting block to adapt to different sizes of bladders.

[0021] Preferably, the adjusting block is equipped with a blower that blows air toward the bladder clamp.

[0022] By adopting the above technical solution, the glue on the yarn can be quickly dried by the blower during the bladder winding process, thereby improving the efficiency of bladder production.

[0023] Preferably, the blower is hinged to the adjusting block so that the blower can be in a position blowing air toward the bladder clamp or flipped to a position for yielding.

[0024] By adopting the above technical solution, after the bladder is wrapped with yarn, the blower is flipped so that it is in a clearance position, which makes it easier to pick up and put down the bladder on the bladder clamp.

[0025] Preferably, the mounting frame is provided with a ball storage rack for temporarily storing ball bladders.

[0026] By adopting the above technical solution, the ball outlet frame set on the mounting frame facilitates the replacement of the ball bladder on the ball bladder clamp, thereby improving the efficiency of the ball bladder winding yarn.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The lifting seat is driven up and down by the drive component. Since the support arm is hinged on the lifting seat, it can be driven to close or open, so as to adapt to different sizes of ball bladders. This makes it easy to operate and adjust the opening size of the ball bladder clamp to adapt to the size of the placed ball bladder. Moreover, it can flexibly adjust the position of the ball bladder to control the accuracy of the yarn winding position without stopping the machine. 2. By installing the drive motor at the bottom of the lifting plate through the transmission assembly, the weight of the support arm is significantly reduced, thereby improving the stability of the support arm during rotation and improving the quality of the yarn winding of the ball; at the same time, during the yarn winding process, the yarn will not get caught on the output shaft of the drive motor, which would damage the motor.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a CNC ball-shaped yarn winding machine. (Refer to...) Figure 1 and Figure 2The CNC ball-winding machine includes an electrical control box 1, a ball clamp 2, a rotating frame 3, a main shaft 4, and a drive mechanism 5. The main shaft 4 is rotatably mounted inside the electrical control box 1 and extends vertically outward from the outside of the electrical control box 1. The drive mechanism 5 is installed inside the electrical control box 1 and is used to drive the main shaft 4 to rotate. The rotating frame 3 is fixedly mounted on the upper end of the main shaft 4, and the ball clamp 2 is mounted on the rotating frame 3 for holding the ball. The drive mechanism 5 drives the main shaft 4 to rotate, thereby driving the rotating frame 3 and the ball clamp 2 to rotate. Specifically, the drive mechanism 5 includes a drive motor 51 and a pulley set 52. The drive motor 51 is mounted inside the electrical control box 1 via a bracket 311. The output shaft of the drive motor 51 is connected to the main shaft 4 via the pulley set 52. A controller 11 is installed on one side of the electrical control box 1, and the other side of the electrical control box 1 provides installation space for the main shaft 4 and the drive mechanism 5. The upper surface of the electrical control box 1 is covered with a protective cover 12 with an opening at the top. The rotating frame 3 and the ball bladder clamp 2 are located inside the protective cover 12. The ball bladder can be placed on the ball bladder clamp 2 through the opening at the top of the protective cover 12.

[0036] Reference Figure 2 and Figure 3 Specifically, the rotating frame 3 includes a rotating base 31, a mounting ring 32, a lifting seat 33, and multiple vertical rods 34. The rotating base 31 is horizontally fixed on the upper end of the main shaft 4. The mounting ring 32 is located above the rotating base 31. The multiple vertical rods 34 are vertically distributed and fixed between the rotating base 31 and the mounting ring 32. The lifting seat 33 is located between the rotating base 31 and the mounting ring 32, and is movably inserted through the vertical rods 34 via guide sleeves. The bladder clamp 2 includes multiple support arms 21 and multiple connecting rods 22. The mounting ring 32 has a hollow center. The multiple support arms 21 are arranged circumferentially on the rotating frame 3. The lower ends of the support arms 21 pass through the center of the mounting ring 32 and are hinged to the lifting seat 33. The upper ends of the connecting rods 22 are connected to the outer side of the middle position of the support arms 21, and the lower ends are hinged to the upper surface of the mounting ring 32. A driving component is provided on the rotating base 31. The output shaft of the driving component is connected to the bottom of the lifting seat 33 to drive the lifting seat 33 to move up and down. In this embodiment, the driving component is an electric cylinder 23. The electric cylinder 23 drives the lifting seat 33 to move up and down. Since the lower end of the support arm 21 is hinged to the lifting seat 33, and the upper side is hinged to the mounting ring seat 32 through the connecting rod 22, the support arm 21 can swing at a certain angle, thereby realizing the closing or opening of the ball bladder clamp 2. This allows it to adapt to ball bladders of different sizes, making it easy to adjust the opening size of the ball bladder clamp 2 to fit the size of the placed ball bladder. Moreover, it does not require stopping the machine, and can flexibly adjust the position of the ball bladder, thereby controlling the accuracy of the yarn winding position.

[0037] Reference Figure 3 and Figure 4Furthermore, it also includes a ball-bladder reversing mechanism 6, which includes a transmission wheel 61, a transmission motor 62, and a transmission assembly 63. The transmission wheel 61 is rotatably connected to the upper end of the support arm 21 via a rotating shaft. The vertical transmission motor 62 is installed at the bottom of the lifting seat 33, and the transmission assembly 63 is located between the output shaft of the transmission motor 62 and the transmission wheel 61. Specifically, the transmission assembly 63 includes a helical gear set 631, a cover 632, a transmission rod 633, and a universal coupling 634. The lifting seat 33 has a through-hole 331. The output shaft of the transmission motor 62 extends through the through-hole 331 to the top of the lifting seat 33. The output shaft of the transmission motor 62 is connected to one end of the universal coupling 634, and the other end of the universal coupling 634 is connected to the transmission rod 633. The shaft of the transmission wheel 61 extends to the other side of the support arm 21. One helical gear of the helical gear set 631 is coaxially and fixedly connected to the shaft, and the transmission rod 633 is coaxially and fixedly connected to the other helical gear. The cover 632 covers the helical gear set 631. After the bladder is placed on the bladder clamp 2, the bladder contacts the transmission wheel 61. The transmission motor 62 drives the transmission assembly 63 to rotate the transmission wheel 61, thus causing the bladder to rotate. During the rotation of the bladder, the transmission wheel 61 causes the bladder to change direction, thereby ensuring that the yarn is evenly wound around the bladder. Furthermore, the transmission assembly 63 connects the transmission motor 62 to the bottom of the lifting plate, significantly reducing the weight of the support arm 21. This improves the stability of the support arm 21 during rotation and enhances the quality of the yarn winding in the bobbin, preventing unstable vibration of the support arm 21 due to centrifugal force during rotation caused by excessive weight. It also prevents yarn from getting caught on the output shaft of the transmission motor 62, thus avoiding motor damage. Moreover, the transmission motor 62's output is reduced in speed through the transmission assembly 63, resulting in more stable output from the transmission wheel 61.

[0038] Reference Figure 2 and Figure 3 A bracket 311 is provided in the middle of the rotating base 31. The electric cylinder 23 is mounted on the bracket 311. The main shaft 4 is hollow. A through hole 312 is provided in the middle of the rotating base 31, which is connected to the main shaft 4. A through hole conductive slip ring 41 is connected to the main shaft 4. The power lines of the drive motor 62 and the electric cylinder 23 extend through the inside of the main shaft 4 and are connected to the wire slip ring. The power lines are connected to the controller 11 through the conductive slip ring.

[0039] Reference Figure 3 It also includes multiple auxiliary wheels 64, which are rotatably connected to the support arm 21 at intervals along the circumferential direction, so that the drive wheel 61 and the auxiliary wheels 64 are distributed and installed on two adjacent support arms 21. In this embodiment, there are six support arms 21, of which three are drive wheels 61 and three are auxiliary wheels 64. By distributing the auxiliary wheels 64 adjacent to each other on the support arm 21 on one side of the drive wheel 61, the stability of the bladder's rotation on the bladder clamp 2 is improved.

[0040] Reference Figure 1 and Figure 5 Furthermore, a mounting bracket 7 is provided on one side of the electrical control box 1. A limiting component 8 is provided on the mounting bracket 7. The limiting component 8 includes a pusher and a limiting block 82. The pusher is mounted on the mounting bracket 7, and the limiting block 82 is mounted on the output shaft of the pusher, so that the pusher drives the limiting block 82 to be positioned above the ball clamp 2. This allows for a limiting position near the top of the ball or a clearance position away from the top of the ball. In this embodiment, the pusher is a cylinder 81. During the rotation and yarn winding process of the ball clamp 2, the limiting block 82 mounted on the top of the ball limits the movement, preventing the ball from jumping out of the ball clamp 2. After the ball is wound, the cylinder 81 pushes the limiting block 82 away from the top of the ball, facilitating the removal and placement of the ball on the ball clamp 2.

[0041] The mounting bracket 7 is equipped with an adjusting component 9 for adjusting the vertical position of the limiting component 8. The adjusting component 9 includes an adjusting block 91 and a lead screw 92. The mounting bracket 7 includes a mounting rod 71 vertically mounted on the electrical control box 1 and two fixing blocks 72 horizontally positioned at the upper end of the mounting rod 71. The lead screw 92 is vertically rotatably connected between the two fixing blocks 72. The adjusting block 91 is threadedly connected to the lead screw 92 and movably passes through the mounting rod 71. A pushing component is mounted on the adjusting block 91. A rotating handle 93 is fixedly mounted on the upper end of the lead screw 92. By rotating the lead screw 92, the vertical position of the adjusting block 91 threadedly connected to the lead screw 92 can be adjusted, thereby adjusting the position of the limiting block 82 to accommodate different sized bladders.

[0042] A blower 73 is mounted on the adjusting block 91, blowing air towards the bladder clamp 2. During the bladder winding process, the blower 73 quickly dries the glue on the yarn, thereby improving the efficiency of bladder production. Furthermore, the blower 73 is hinged to the adjusting block 91, allowing it to be positioned either in the air-blowing direction towards the bladder clamp 2 or flipped into a clearance position. After the bladder winding is complete, flipping the blower 73 allows it to be placed in the clearance position, facilitating the loading and unloading of bladders from the bladder clamp 2. A ball storage rack 74 is provided on the mounting frame 7 for temporary storage of bladders. The ball dispensing rack on the mounting frame 7 facilitates the replacement of bladders on the bladder clamp 2, thereby improving the efficiency of bladder winding.

[0043] The implementation principle of a CNC ball-shaped yarn winding machine according to an embodiment of this application is as follows: the drive mechanism 5 controlled by the electrical control box 1 drives the main shaft 4 to rotate the ball clamp 2, and at the same time, the transmission motor 62 drives the transmission wheel 61 to drive, so that the ball placed on the ball clamp 2 continuously changes direction and rotates to wind yarn. Meanwhile, the lifting seat 33 is driven up and down by the electric cylinder 23, which drives the support arm 21 to swing, so that the ball clamp 2 closes or opens, realizing the lifting of the ball. This can adapt to ball of different sizes, without stopping the machine, and can flexibly adjust the position of the ball to control the accuracy of the yarn winding position.
