Description

Technical Field

[0001] This utility model relates to the field of cage winch technology, specifically to a cage winch loading device. Background Technology

[0002] In the manufacturing of power cables, communication cables, and magnet wire, the cage stranding machine is a key piece of equipment widely used for stranding conductors or insulated cores. Its winding device is mainly used to carry and fix the coil (such as copper wire, aluminum wire, or insulated core), providing stable wire tension during continuous stranding. However, existing winding devices have the following prominent problems: traditional winding devices mostly use mechanical locking structures or bolt fixing methods, which require disassembling multiple fasteners when replacing the coil, making the operation cumbersome and time-consuming, seriously affecting production efficiency, especially in multi-variety, small-batch production scenarios; the coil rotates with the rotating disc during operation, which can easily cause wire tension fluctuations or tangled windings when the coil is fed. To address these problems, there is an urgent need to design a cage stranding machine winding device that is simple in structure, easy to operate, and highly adaptable. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a wire feeding device for a cage winding machine, which effectively solves the problems of wire tension fluctuation caused by coil rotation and the inability to quickly replace the fixed coil.

[0004] The technical solution is as follows: This utility model includes an upper wire frame, a fixed shaft is fixedly connected to the right side of the upper wire frame, a rotatable rotating disk is provided on the left side of the fixed shaft, and multiple fixed frames that are evenly distributed along the circumference and always remain horizontal are rotatably connected to the left side of the rotating disk. Fixed pins that can move relative to or away from each other are provided on the front and rear sides of the fixed frames. A coil is provided in the middle of the fixed frame, and the front and rear sides of the coil are respectively inserted into the fixed pins on their corresponding sides. A lead screw is coaxially threaded in the fixed pin. A wire tube is provided on the left side of the upper wire frame, and a rotating disk is rotatably connected to the wire tube. The fixed frames are rotatably connected to the rotating disk.

[0005] A fixed gear is fixedly connected to the left end of the fixed shaft. Multiple connecting gears are rotatably connected to the rotating disk, distributed along the circumference of the fixed gear and corresponding one-to-one with the fixed frame. The connecting gears mesh with the fixed gears. A rotating gear that can mesh with the connecting gear on its corresponding side is fixedly connected to the right end of the fixed frame.

[0006] A rotating frame is fixedly connected to the right end of the rotating disk. The rotating frame is coaxial with the fixed shaft. A spur gear is fixedly connected to the right end of the rotating frame. A drive motor is provided on the right side of the upper frame. A spur gear that can mesh with the spur gear is fixedly connected to the output end of the drive motor.

[0007] One end of the lead screw is fixedly connected to a rotating gear, and the front and rear sides of the fixing frame are respectively provided with racks that can move left and right, and the racks can mesh with the rotating gears on their corresponding sides.

[0008] The fixed frame has L-shaped push rods slidably connected to its front and rear sides respectively. The upper ends of the two push rods are respectively provided with inclined grooves. The two inclined grooves are V-shaped. One end of the rack is fixedly connected to a movable plate. The movable plate is fixedly connected to a movable pin that can be inserted into the inclined groove on its corresponding side.

[0009] A lever is slidably connected to the left side of the fixed frame, and a drive plate is fixedly connected to the lower end of the lever. Two drive slots are provided on the drive plate, which are symmetrical front and back and have the left side inside and the right side outside. A drive pin that can be inserted into the corresponding drive slot is fixedly connected to the left side of the push rod.

[0010] The upper end of the fixed frame is fixedly connected with ratchet racks located on the front and rear sides of the lever. The upper side of the lever is rotatably connected to a rotating shaft via a torsion spring. The front and rear sides of the rotating shaft are fixedly connected with ratchet blocks that can mesh with the corresponding ratchet racks.

[0011] Beneficial effects:

[0012] This invention utilizes a gear rack and screw transmission structure. By moving the lever, the front and rear fixing pins can be quickly extended or retracted synchronously through components such as the drive groove and tilting groove. This enables rapid locking and releasing of the coil, eliminating the need for traditional bolt tightening, significantly shortening the line changeover time, and improving product production efficiency.

[0013] This invention, by setting up a fixed gear, a connecting gear, and a rotating gear to mesh, ensures that the rotation angle and revolution angle of the fixed frame cancel each other out during revolution, maintaining a horizontal state at all times. This avoids wire tension fluctuations or tangled winding caused by coil rotation, ensuring stable wire output during stranding and improving product quality.

[0014] This utility model features a self-locking structure with a ratchet rack and ratchet block, and a torsion spring that ensures constant engagement when there is no external force. This locks the lever position, prevents the fixing pin from accidentally retracting, and ensures the coil is in a stable fixed state. At the same time, the structure is reasonably designed, the wire changing operation is simple, and the manual labor intensity and operational risks are reduced. Attached Figure Description

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Depend on Figures 1 to 6 The device includes an upper wire frame 1, a fixed shaft 2 fixedly connected to the right side of the upper wire frame 1, a rotatable rotating disk 3 on the left side of the fixed shaft 2, and multiple fixed frames 4 evenly distributed along its circumference and always kept horizontally connected to the left side of the rotating disk 3. Fixed pins 5 that can move relative to or away from each other are provided on the front and rear sides of the fixed frames 4. A coil 6 is provided in the middle of the fixed frame 4, and the front and rear sides of the coil 6 are respectively inserted into the fixed pins 5 on their corresponding sides. A screw rod 7 is coaxially threaded into the fixed pin 5. A wire tube 8 is provided on the left side of the upper wire frame 1, and a rotating disk 9 is rotatably connected to the wire tube 8. The fixed frames 4 and the rotating disk 9 are rotatably connected.

[0024] As shown in the figure, the upper wire frame 1 is set up to facilitate the support structure and bear the core components such as the fixed shaft 2, rotating disk 3, and fixed frame 4. The fixed shaft 2 is set as the rotation center axis of the rotating disk 3. The fixed shaft 2 and the wire tube 8 are coaxial. The fixed frame 4, fixed pin 5, and coil 6 are set up to facilitate the use of the fixed frame 4 to support the coil 6, and the coil 6 can be quickly fixed by moving the fixed pin 5 in or out. The fixed frame 4 can always maintain a horizontal state during the rotation of the rotating disk 3, which can ensure the stability of the coil 6. At the same time, when replacing the coil 6, there is no need to position the orientation of the coil 6, which facilitates the replacement of the coil 6. The lead screw 7 can pass through the wire. The rotation of the fixing pin 5 causes the fixing pin 5 to move back and forth. The wire tube 8 is fixed to the left side of the upper wire frame 1 as the outlet of the stranded wire. The rotating disk 9 is set to support the rotation of the fixing frame 4. The fixing pin 5 is driven to move synchronously through the lead screw 7, so as to realize the quick locking and releasing of the coil 6, eliminating the tedious steps of traditional bolt tightening and significantly improving the replacement efficiency. At the same time, the fixing frame 4 always remains horizontal when the rotating disk 3 rotates, so that the coil 6 can be directly inserted and removed without adjusting the angle. It can also be used in conjunction with the loading robot to replace the coil 6, greatly reducing downtime. The coil 6 always maintains a horizontal state, avoiding wire tension fluctuations or tangling.

[0025] A fixed gear is fixedly connected to the left end of the fixed shaft 2. Multiple connecting gears 11 are rotatably connected to the rotating disk 3, which are distributed around the circumference of the fixed gear and correspond one-to-one with the fixed frame 4. The connecting gears 11 mesh with the fixed gears. A rotating gear 12 that can mesh with the connecting gear 11 on its corresponding side is fixedly connected to the right end of the fixed frame 4.

[0026] As shown in the figure, the fixed gear, connecting gear 11, and rotating gear 12 ensure that when the fixed frame 4 revolves around the fixed axis 2, its rotation angle is opposite to and equal to its revolution angle. This counteracts the tilt change caused by the rotating disk 9, keeping the fixed frame 4 horizontal at all times. The horizontal state of the fixed frame 4 is dynamically maintained by the gear meshing system. Regardless of the position of the rotating disk 3, the rotation of the fixed frame 4 will counteract the tilt caused by the revolution, ensuring the stability of the coil 6. This design eliminates the need for manual adjustment of the coil 6 angle, achieving a quick replacement effect.

[0027] The rotating disk 3 is fixedly connected to a rotating frame 13 at its right end. The rotating frame 13 is coaxial with the fixed shaft 2. A spur gear 14 is fixedly connected to the right end of the rotating frame 13. A drive motor 15 is provided on the right side of the upper wire frame 1. A spur gear 16 that can mesh with the spur gear 14 is fixedly connected to the output end of the drive motor 15.

[0028] As shown in the figure, the drive motor 15, spur gear 16, straight gear 14, and rotating frame 13 are configured so that the rotation of the drive motor 15 drives the straight gear 14 to rotate via the spur gear 16, and then drives the rotating disk 3 to rotate via the rotating frame 13. Through the meshing transmission of the drive motor 15, spur gear 16, and straight gear 14, the rotating disk 3 is automatically rotated, which drives the fixed frame 4 to revolve around the fixed shaft 2. At the same time, the gear meshing system makes the rotation angle of the fixed frame 4 cancel out the revolution angle, ensuring that the coil 6 always remains horizontal and provides rotational power for the stranded wire.

[0029] One end of the lead screw 7 is fixedly connected to a rotating gear 17, and the front and rear sides of the fixing frame 4 are respectively provided with racks 18 that can move left and right. The racks 18 can mesh with the rotating gears 17 on their corresponding sides.

[0030] As shown in the figure, through the meshing transmission of the rotating gear 17 and the rack 18, the rotation of the lead screw 7 can synchronously drive the fixed pins 5 on the front and rear sides to move, thereby realizing the rapid locking or releasing of the coil 6.

[0031] The fixed frame 4 has L-shaped push rods slidably connected to its front and rear sides respectively. The upper ends of the two push rods are respectively provided with inclined grooves 20. The two inclined grooves 20 are in the shape of an octagon. One end of the rack 18 is fixedly connected to a movable plate 21. The movable plate 21 is fixedly connected with a movable pin that can be inserted into the inclined groove 20 on its corresponding side.

[0032] As shown in the figure, a push rod, an inclined groove 20, a movable plate 21, and a movable pin are provided to facilitate the movement of the racks 18 on the front and rear sides.

[0033] The left side of the fixed frame 4 is slidably connected to a lever, and the lower end of the lever is fixedly connected to a drive plate. The drive plate has two symmetrical drive slots 24 with the left side inside and the right side outside. The left side of the push rod is fixedly connected to a drive pin that can be inserted into the corresponding drive slot 24.

[0034] As shown in the figure, the lever, drive plate, drive slot 24 and drive pin are set so that the lever can drive the drive plate to move, which in turn drives the push rods on the front and rear sides to move, which in turn drives the fixing pins 5 on the front and rear sides to extend or retract synchronously, so as to quickly fix the coil 6.

[0035] The upper end of the fixed frame 4 is fixedly connected with ratchet racks 25 located on the front and rear sides of the lever. The upper side of the lever is rotatably connected to a rotating shaft via a torsion spring. The front and rear sides of the rotating shaft are fixedly connected with ratchet blocks 26 that can mesh with the corresponding ratchet racks 25.

[0036] As shown in the figure, the ratchet 25, torsion spring, pivot, and ratchet block 26 are designed to fix the position of the lever by meshing the ratchet 25 and the ratchet block 26, preventing the fixing pin 5 from being released at will. The torsion spring ensures that the ratchet block 26 and the ratchet 25 remain engaged in the absence of external force.

[0037] When using this utility model, the coil 6 is placed horizontally in the middle of the target fixing frame 4. Without adjusting the angle, the lever on the fixing frame 4 is turned to the right. The drive groove 24 of the drive plate pushes the push rods on both sides to move outward. The push rod drives the rack 18 to move laterally through the inclined groove 20, which drives the rotating gear 17 to rotate the lead screw 7 synchronously. The two lead screws 7 push the front and rear fixing pins 5 to move towards the coil 6 and insert them into the insertion holes on both sides of the coil 6 to complete the fixing. After the lever is released, the torsion spring makes the ratchet block 26 mesh with the ratchet rack 25 to lock the position of the lever and prevent the fixing pin 5 from retracting.

[0038] The drive motor 15 meshes with the spur gear 14 through the spur gear 16, driving the rotating frame 13 and the rotating disk 3 to revolve around the fixed shaft 2. The fixed gear meshes with the connecting gear 11, and the connecting gear 11 drives the rotating gear 12 of the fixed frame 4, so that the rotation angle and the revolution angle of the fixed frame 4 cancel each other out. The coil 6 always maintains a horizontal state to avoid wire tension fluctuations or tangling. When the fixed frame 4 rotates with the rotating disk 3, the wire is stably output through the left wire tube 8 to meet the high-speed stranding requirements.

[0039] Move the ratchet block 26 on the lever upwards to disengage it from the ratchet rack 25, releasing the self-locking mechanism. Move the lever in the opposite direction to pull the push rod inwards through the drive groove 24. The rack 18 drives the rotating gear 17 to reverse the screw 7, and the fixing pin 5 simultaneously exits the coil 6 insertion hole, releasing the fixing of the coil 6. Directly remove the old coil 6 horizontally, replace it with the new coil 6, and re-fix the new coil 6 according to the first step of the process to continue working.
