[0025] 1-7, the present invention provides a technical solution:

[0026] A wire core winding and pushing device includes a wire pushing motor 1, characterized in that: a winding motor 2 is connected to the axis of the wire pushing motor 1, one end of the winding motor 2 is connected to a nozzle connecting block 3, an inner shaft sliding sleeve 4 is provided at the axis of the nozzle connecting block 3, a tension wire frame 5 is connected to the side wall of the wire pushing motor 1, one end of the wire pushing motor 1 is connected to an image sensor component 6, and a wire core winding area or a wound wire core 7 is provided at one end of the wire pushing motor 1 and on the side wall of the image sensor component 6;

[0027] In this embodiment, referring to FIG4 , the winding motor 2 reverses to wind the wire, and the wire pushing motor 1 drives the tension wire rack 5 to perform reciprocating motion in the winding area according to the set stroke (i.e., the wire core thickness) to arrange the wire and wind the wire, thereby winding a bobbin-free wire core 7 with a predetermined target number of turns layer by layer in an orderly manner.

[0028] In this embodiment, referring to Figure 5, a rotating screw rod 201 is designed at the tail end of the winding motor 2 shaft, and the wire pushing motor 1 rotates forward with a small torque, exerting partial thrust on the winding shaft of the winding motor 2, so that the winding shaft of the winding motor 2 obtains partial damping, and the winding motor 2 rotates forward, and the rotating screw rod 201 and the wire pushing motor 1 can realize axial operation to the bobbin case, and an inner thread head winding frame 604 is provided on the top of the bobbin 601, which cooperates with the bobbin case bobbin buckle to push the inner thread head into the buckle of the bobbin case bobbin, thereby completing the process of transporting the bobbin core and buckling the inner thread head without a bobbin core.

[0029] In this embodiment, referring to Figure 6 , the thread-pushing motor 1 rotates forward at full torque, pushing the thread core 7 onto the bobbin within the bobbin case. Simultaneously, the tensioning frame 5 pushes the outer thread end of the thread core 7 into the one-way thread groove of the bobbin case, securing it there and preventing it from escaping, thus completing the thread-pushing and thread-locking process.

[0030] In this embodiment, referring to Figure 7, the wire pushing motor 1 reverses and retreats a distance, so that the tension wire rack 5 presses on the winding shaft of the winding motor 2, and the winding shaft of the winding motor 2 obtains corresponding pressure and thus obtains corresponding damping. The winding motor 2 reverses, and the rotating screw rod 201 can axially retreat, and the wire pushing motor 1 retreats synchronously. When the rotating screw rod 201 retreats to the designed vertex and continues to reverse, the torque of the winding shaft of the winding motor 2 will be greater than the damping torque generated by the pressure of the tension wire rack 5. The winding shaft of the winding motor 2 is in a rotating state, and is linked with the wire pushing motor 1 to cooperate with the tension wire rack to wind the wire on the inner wire head winding rack 604 as the inner wire head of the next core, and then outputs a continue instruction to the sewing equipment, thereby completing the reset of the device and the inner wire head winding process.

[0031] Furthermore, a rotating screw 201 is connected to the inner cavity of the winding motor 2, a protective tube 202 is connected to the inner cavity of the rotating screw 201, an inner shaft sleeve 4 is provided in the inner cavity of the protective tube 202, an air channel 401 is provided on the inner shaft sleeve 4, one end of the inner shaft sleeve 4 extends to the outside of the air nozzle connecting block 3, and the other end of the inner shaft sleeve 4 extends to the inner cavity of the image sensor component 6, an air inlet hole 301 is provided on the side wall of the air nozzle connecting block 3, and the image sensor component 6 includes a bobbin 601, which is connected to the driving end of the winding motor 2 The inner cavity of the bobbin 601 is provided with an air jet 602 connected to the airway 401 and an image sensor 603, and the other end of the bobbin 601 is provided with an inner wire head winding frame 604, and the tension wire frame 5 is connected to the side wall of the wire pushing motor 1 through the rotating shaft 501, wherein the tension wire frame 5, the rotating shaft 501 and the wire pushing motor 1 are connected by a tension spring 502, and the wire core 7 is connected to the side wall of the bobbin 601, wherein the connection mode of the wire core 7 and the bobbin 601 is a sliding connection, so that the device can operate smoothly when in use.

[0032] The working process of the present invention is as follows: When using the core winding and pushing device,

[0033] 1. Bobbin-less core winding: The winding motor 2 rotates in reverse to wind the thread, while the thread-pushing motor 1 drives the tension bobbin 5 to move back and forth in the winding area according to the set stroke (i.e., thread core thickness), winding a bobbin-less thread core 7 with a pre-set target number of turns in an orderly manner layer by layer.

[0034] 2. Transfer of bobbin-free thread core: A rotating screw 201 is designed at the tail end of the winding motor 2 shaft. The thread pushing motor 1 rotates forward with a small torque, exerting partial thrust on the winding shaft of the winding motor 2, so that the winding shaft of the winding motor 2 obtains partial damping. The winding motor 2 rotates forward, and the rotating screw 201 and the thread pushing motor 1 can realize axial movement to the bobbin case. An inner thread head winding frame 604 is provided on the top of the bobbin 601, which cooperates with the bobbin buckle of the shuttle bed to push the inner thread head into the buckle of the shuttle bed bobbin, thereby completing the process of transferring the thread core without a bobbin and buckling the inner thread head.

[0035] 3. Loading the bobbin thread without a bobbin: The thread-pushing motor 1 rotates forward at full torque, pushing the thread core 7 onto the bobbin sleeved within the bobbin case. Simultaneously, the tension bobbin 5 pushes the outer thread end of the thread core 7 into the one-way thread groove of the bobbin case, securing it in the groove and preventing it from falling out. This completes the thread-pushing and thread-thread ...

[0036] 4. Device reset: the wire pushing motor 1 reverses and retreats a certain distance, so that the tension wire rack 5 presses on the winding shaft of the winding motor 2. The winding shaft of the winding motor 2 obtains corresponding pressure and thus obtains corresponding damping. The winding motor 2 reverses and the rotating screw 201 can axially retreat, and the wire pushing motor 1 retreats synchronously. When the rotating screw 201 retreats to the designed vertex and continues to reverse, the torque of the winding shaft of the winding motor 2 will be greater than the damping torque generated by the pressure of the tension wire rack 5. The winding shaft of the winding motor 2 is in a rotating state, and is linked with the wire pushing motor 1 to cooperate with the tension wire rack to wind the wire on the inner thread head winding rack 604 as the inner thread head of the next core, and then outputs a continue instruction to the sewing equipment, thereby completing the reset of the device and the inner thread head winding process.

[0037] 5. Sewing continues: When the sewing equipment is started, the shuttle bed hooks the needle loop and wraps the outer thread end, bringing it into the shuttle skin and completing a stitch, that is, cutting the connection between the outer thread end pushed into the thread core and the inner thread end of the newly wound thread, thus completing the entire process of winding, pushing and resetting. The device then executes step 1 to wind the next thread core;

[0038] The inner cavity of the bobbin 601 is provided with an air jet port 602 connected to the air channel 401, which can be used by the host computer to clean the shuttle bed from dust and thread ends by air jets according to real-time working conditions; the inner cavity of the bobbin 601 is provided with an image sensor 603, which can be used by the host computer to collect video data of the real-time working status of the shuttle bed and thread core.

[0039] Through the coordinated operation of the thread pushing motor 1, the winding motor 2, the winding shaft 601 and the tension thread frame 5, the device can complete the actions of winding the thread core, transferring the thread core, buckling the inner thread end to the thread shaft, buckling the outer thread end to the shuttle skin, pushing the thread core into the shuttle, etc. in a narrow space, and still leaving enough space for manual operation. When special working conditions or the device fails, traditional manual intervention can also be used to change the bobbin case / bobbin for sewing.
