Description

Technical Field

[0001] This invention relates to sewing machine technology, and more particularly to a fully automatic winding device and winding method. Background Technology

[0002] A sewing machine is a machine that uses one or more thread threads to create one or more stitches on a fabric, so that one or more layers of fabric are interwoven or sewn together.

[0003] Most existing sewing machines have a rotary hook device located below the needle plate. Inside the rotary hook device is a bobbin with a bobbin thread wound around it, which works in conjunction with the top thread on the needle to complete the sewing of the fabric. However, sewing machines usually operate continuously, while the amount of thread on the bobbin is limited. Therefore, in order to meet the needs of continuous operation, the bobbin in the rotary hook device needs to be changed frequently during the sewing machine's operation.

[0004] During the shuttle change process, the removed bobbin needs to be wound with new bobbin thread. This requires manual hooking and winding of the bobbin thread, which is inefficient. Summary of the Invention

[0005] To address the shortcomings of the prior art, this invention provides a fully automatic winding device and method that can automatically complete the hooking and winding of the bobbin.

[0006] The technical problem to be solved by the present invention is achieved through the following technical solution:

[0007] A fully automatic winding device includes a mounting plate and a winding module, a wire clamping module, and a wire cutting module disposed on the mounting plate.

[0008] The winding module includes a rotating shaft, a shuttle taker, and a winding rotation mechanism. The shuttle taker is sleeved on the periphery of the rotating shaft, and the winding rotation mechanism drives the rotating shaft and the shuttle taker to rotate synchronously.

[0009] The wire clamping module includes a ring bracket, a wire clamp, and a wire clamping revolving mechanism. The ring bracket surrounds the periphery of the shuttle taker, the wire clamp is disposed on the periphery of the ring bracket, and the wire clamping revolving mechanism drives the ring bracket to rotate, thereby causing the wire clamp to revolve around the rotation axis.

[0010] The tangent module includes a cutter and a tangent moving mechanism. The tangent moving mechanism drives the cutter to move radially along the rotation axis. The cutter includes a tangent table and a cutter head. The cutting edge of the cutter head faces the opposite direction to the revolution of the wire clamp. When the cutter moves closer to the rotation axis, the cutter head is located within the inner circumference of the revolution of the wire clamp. When the cutter moves away from the rotation axis, the cutter head is located outside the outer circumference of the revolution of the wire clamp.

[0011] The inner side of the wire clamp is provided with a tangent platform, and the outer side of the wire clamp is provided with a clamping opening; when the cutter moves close to the rotating shaft, and the wire clamp revolves to the side facing the cutter, the cutter head is in contact with the tangent platform.

[0012] Furthermore, the wire clamp protrudes forward on the periphery of the annular bracket so that the wire clamping opening is aligned with the winding groove of the bobbin located in front of the shuttle taker; the connecting part and the cutting head of the cutter are perpendicular to each other, wherein the connecting part is located in front of the wire clamp and the cutting head extends backward.

[0013] Furthermore, the wire clamp includes a baffle, a base, and a wire clamping spring. The baffle and the base are arranged opposite each other. The wire cutting platform is connected to the inner side between the baffle and the base. The wire clamping opening is located on the outer side between the baffle and the base. The wire clamping spring is disposed inside the wire clamping opening.

[0014] Furthermore, the winding module also includes a shuttle-taking and moving mechanism, which drives the shuttle taker to move axially along the rotating shaft.

[0015] Furthermore, the fully automatic winding device also includes a wire-picking module disposed on the mounting plate, the wire-picking module comprising:

[0016] A wire-picking lever and a wire-picking moving mechanism are provided. The wire-picking moving mechanism drives the wire-picking lever to move. When the wire-picking moving mechanism drives the wire-picking lever to the first position, the wire-picking lever is located behind the wire clamp. When the wire-picking moving mechanism drives the wire-picking lever to the second position, the wire-picking lever is located in front of the wire clamp.

[0017] The device includes a wire-picking arm and a wire-picking swing mechanism. The wire-picking swing mechanism drives the wire-picking arm to swing. When the wire-picking swing mechanism drives the wire-picking arm to swing to the fourth position, the wire-picking arm is located within the inner circumference of the wire clamp. When the wire-picking swing mechanism drives the wire-picking arm to swing to the fifth position, the wire-picking arm is located outside the outer circumference of the wire clamp.

[0018] Furthermore, the moving path of the wire-pulling lever also has a third position. When the wire-pulling moving mechanism drives the wire-pulling lever to move to the third position, the wire-pulling lever is located in front of the wire clamp, and the distance between the third position and the wire clamp is greater than the distance between the second position and the wire clamp.

[0019] A winding method includes the following steps:

[0020] Step 200: The winding rotation mechanism and the clamping revolution mechanism drive the rotating shaft, the shuttle taker and the clamping device to rotate synchronously to wind a predetermined number of bottom threads on the bobbin.

[0021] Step 300: The winding rotation mechanism pauses the drive of the rotating shaft and the shuttle taker to rotate, while the wire clamping revolution mechanism continues to drive the wire clamp to revolve around the rotating shaft so that all the wire ends held in the wire clamp are wound around the bobbin.

[0022] Step 400: The wire clamping revolution mechanism pauses driving the wire clamp to revolve around the rotating axis, while the winding rotation mechanism continues to drive the rotating axis and the shuttle taker to rotate synchronously to wind the bobbin with a predetermined thickness of thread.

[0023] Step 500: The winding rotation mechanism pauses the drive of the rotating shaft and the shuttle to rotate, and the tangent moving mechanism drives the cutter to move closer to the rotating shaft;

[0024] Step 600: The wire clamping mechanism continues to drive the wire clamp to revolve around the rotating axis so that the wire clamp passes through the bobbin and the cutter in sequence. When the wire clamp passes the bobbin, it hooks the bobbin into its clamping opening. When the wire clamp passes the cutter, its cutting platform and the cutter head cooperate to cut the bobbin located between the bobbin and the wire clamp.

[0025] Furthermore, the winding method also includes the following steps:

[0026] Step 100: The shuttle moving mechanism first drives the shuttle taker to move closer to the shuttle case located at the front end of the rotating shaft, so that the shuttle taker grips the bobbin inside the shuttle case. Then the shuttle moving mechanism drives the shuttle taker to move away from the shuttle case located at the front end of the rotating shaft, so that the shuttle taker removes the gripped bobbin from the shuttle case.

[0027] Step 700: The shuttle moving mechanism first drives the shuttle taker to move closer to the shuttle case located at the front end of the rotating shaft, so that the shuttle taker pushes the gripped shuttle core into the shuttle case, and then releases the shuttle core. The shuttle moving mechanism then drives the shuttle taker to move away from the shuttle case located at the front end of the rotating shaft.

[0028] Furthermore, in step 200, before the winding rotation mechanism and the clamping revolution mechanism drive the rotating shaft, the shuttle taker and the clamping device to rotate synchronously, the thread-pulling mechanism first drives the thread-pulling rod to move from the first point to the second point to move the bottom thread to the front of the clamping device. The thread-pulling swing mechanism then drives the thread-pulling arm to swing from the fourth point to the fifth point to move the end of the bottom thread close to the bobbin to align with the winding groove of the bobbin.

[0029] Furthermore, in step 200, after the wire-picking swing mechanism drives the wire-picking arm to swing from the fourth position to the fifth position, the wire-picking moving mechanism then drives the wire-picking lever to move from the second position to the third position, so as to move the bottom thread further forward from the wire clamp.

[0030] The present invention has the following beneficial effects: The fully automatic winding device of the present invention can automatically complete the winding process such as bobbin gripping, bobbin wrapping, and bobbin cutting through the cooperation of the winding module, the clamping module, and the cutting module. Through the cooperation of the clamping device and the cutter, the clamping device can hook the bobbin into its clamping opening when it revolves, and cooperate with the cutter to cut the bobbin, so as to form the tail of the previous bobbin and the head of the next bobbin respectively. This not only improves the efficiency of hooking and cutting the bobbin, but also eliminates the need for a special threading module and simplifies the equipment structure.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Example 1

[0046] like Figure 1 and 2 As shown, a fully automatic winding device includes a mounting plate 10 and a winding module 20, a wire clamping module 30, and a wire cutting module 40 disposed on the mounting plate 10.

[0047] The winding module 20 includes a rotating shaft 21, a shuttle taker 22, and a winding rotation mechanism 23. The shuttle taker 22 is sleeved on the periphery of the rotating shaft 21, and the winding rotation mechanism 23 drives the rotating shaft 21 and the shuttle taker 22 to rotate synchronously.

[0048] The wire clamping module 30 includes an annular bracket 31, a wire clamp 32, and a wire clamping revolving mechanism 33. The annular bracket 31 surrounds the periphery of the shuttle taker 22, and the wire clamp 32 is disposed on the periphery of the annular bracket 31. The wire clamping revolving mechanism 33 drives the annular bracket 31 to rotate, thereby driving the wire clamp 32 to revolve around the rotating axis 21.

[0049] The tangent module 40 includes a cutter 41 and a tangent moving mechanism 42. The tangent moving mechanism 42 drives the cutter 41 to move radially along the rotation axis 21. The cutter 41 includes a connecting part 411 and a blade head 412. The cutting edge 413 of the blade head 412 faces the opposite direction to the revolution of the wire clamp 32. When the cutter 41 moves closer to the rotation axis 21, the blade head 412 is located within the inner circumference of the revolution of the wire clamp 32. When the cutter 41 moves away from the rotation axis 21, the blade head 412 is located outside the outer circumference of the revolution of the wire clamp 32.

[0050] The inner side of the wire clamp 32 is provided with a wire cutting platform 321, and the outer side of the wire clamp 32 is provided with a wire clamping opening 322; when the cutter 41 moves close to the rotating shaft 21, and the wire clamp 32 revolves to the side facing the cutter 41, the cutter head 412 is in contact with the wire cutting platform 321.

[0051] The fully automatic winding device of the present invention, through the cooperative winding module 20, the wire clamping module 30 and the wire cutting module 40, can automatically complete the winding process such as bobbin gripping, bobbin wrapping and bobbin cutting. Through the cooperation of the wire clamping device 32 and the cutter 41, the wire clamping device 32 can hook the bobbin c into its clamping opening 322 when it revolves, and cooperate with the cutter 41 to cut the bobbin, so as to form the tail of the previous bobbin b and the head of the next bobbin b respectively. This not only improves the efficiency of hooking and cutting the wire, but also eliminates the need for a special threading module and simplifies the equipment structure.

[0052] For ease of explanation, the side of the wire clamp 32 facing the rotation axis 21 is defined as the inner side of the wire clamp 32, and the side of the wire clamp 32 facing away from the rotation axis 21 is defined as the outer side of the wire clamp 32. The circumference of the inner side of the wire clamp 32 during its revolution is the inner circumference of the wire clamp 32 during its revolution, and the circumference of the outer side of the wire clamp 32 during its revolution is the outer circumference of the wire clamp 32 during its revolution.

[0053] like Figure 15 As shown, the fully automatic winding device of the present invention includes the following steps during winding:

[0054] Step 200: The winding rotation mechanism 23 and the wire clamping revolution mechanism 33 respectively drive the rotating shaft 21, the shuttle taker 22 and the wire clamp 32 to rotate synchronously (the rotating shaft 21 and the shuttle taker 22 rotate on their own axis, and the wire clamp 32 revolves around the axis, and the three have the same angular velocity) to wind a predetermined number of threads c on the bobbin b;

[0055] Step 300: The winding rotation mechanism 23 stops driving the rotating shaft 21 and the shuttle taker 22 to rotate, while the wire clamping revolution mechanism 33 continues to drive the wire clamp 32 to revolve around the rotating shaft 21, so as to wind all the wire ends clamped in the wire clamp 32 onto the bobbin b.

[0056] Step 400: The wire clamping revolution mechanism 33 stops driving the wire clamp 32 to revolve around the rotating shaft 21, and the winding rotation mechanism 23 continues to drive the rotating shaft 21 and the shuttle taker 22 to rotate synchronously, so as to wind a thread c of predetermined thickness on the bobbin b;

[0057] Step 500: The winding rotation mechanism 23 stops driving the rotating shaft 21 and the shuttle taker 22 to rotate, and the tangent moving mechanism 42 drives the cutter 41 to move closer to the rotating shaft 21;

[0058] Step 600: The wire clamping revolving mechanism 33 continues to drive the wire clamp 32 to revolve around the rotating axis 21, so that the wire clamp 32 passes through the bobbin c and the cutter 41 in sequence. When the wire clamp 32 passes the bobbin c, it hooks the bobbin c into its clamping opening 322. When the wire clamp 32 passes the cutter 41, its cutting platform 321 cooperates with the cutter head 412 to cut the bobbin located between the bobbin b and the wire clamp 32.

[0059] When the bottom thread c located between the bobbin b and the thread clamp 32 is cut, the bottom thread c remaining in the bobbin b and the bottom thread c remaining in the thread clamp 32 respectively form the tail of the previous bobbin b and the head of the next bobbin b. In this way, except for the first bobbin b which needs to be manually hooked, the remaining bobbins b can complete the hooking and cutting processes synchronously in step 600 through the revolution of the thread clamp 32, which greatly improves the efficiency of hooking and cutting.

[0060] In this embodiment, the rotating shaft 21 and the shuttle taker 22 rotate clockwise, while the wire clamp 32 revolves clockwise. The wire cutting module 40 is located below the winding module 20 and the wire clamping module 30, and the blade 413 of the cutter 41 faces to the right. The bottom thread c enters from the right side of the winding module 20 when winding.

[0061] At the end of step 500, as Figure 3As shown, the wire clamp 32 remains above the rotating shaft 21, and the blade head 412 moves from outside the outer circumference of the wire clamp 32 to within the inner circumference of the wire clamp 32. In step 600, as... Figure 4 As shown, the wire clamp 32 rotates clockwise from above the rotating shaft 21 to the left side of the cutter 41, and when the wire clamp 32 rotates to the right side of the rotating shaft 21, it hooks the bottom thread c into its clamping opening 322, as shown. Figure 5 As described above, when the wire clamp 32 revolves to the right side of the cutter 41, it pulls the bottom thread c down to below the cutter head 412, as... Figure 6 As shown, when the wire clamp 32 revolves to a position below the rotating shaft 21, its tangent platform 321 and the blade head 412 respectively cooperate to cut the bottom thread c from the left and right sides, as shown. Figure 7 As shown, when the wire clamp 32 revolves to the left side of the cutter 41, the cutter head 412 moves from inside the inner circumference of the wire clamp 32 to outside the outer circumference of the wire clamp 32.

[0062] like Figure 8 As shown, the wire clamp 32 protrudes forward on the periphery of the annular bracket 31 so that the wire clamping opening 322 is aligned with the winding groove of the bobbin b located in front of the shuttle taker 22. The wire clamp 32 includes a baffle 323, a base 324, and a wire clamping spring 325. The baffle 323 and the base 324 are arranged opposite each other. The tangent platform 321 is connected to the inner side between the baffle 323 and the base 324. The wire clamping opening 322 is located on the outer side between the baffle 323 and the base 324. The wire clamping spring 325 is disposed inside the wire clamping opening 322.

[0063] Preferably, on the inner side, the base 324, baffle 323 and tangent platform 321 are flush to form an arc concave surface that can fit with the blade head 412. On the outer side and the two sides adjacent to the outer side, the tangent platform 321 is recessed by about 2-5mm compared to the base 324 and baffle 323 to form a U-shaped hook or C-shaped hook-shaped clamping opening 322, so as to hook the bottom line c in step 600.

[0064] The connecting portion 411 and the blade head 412 of the cutter 41 are perpendicular to each other. The connecting portion 411 is located in front of the wire clamp 32, and the blade head 412 extends rearward to avoid interference between the raised cutter 41 and the protruding wire clamp 32 during its revolution.

[0065] In this embodiment, the shuttle taker 22 includes a ring electromagnet. When energized, the ring electromagnet generates magnetic force to magnetically attract and hold the shuttle core b. When de-energized, it loses magnetic force to release the shuttle core b.

[0066] like Figure 2 As shown, the winding module 20 also includes a shuttle moving mechanism 24, which drives the shuttle taker 22 to move axially along the rotating shaft 21.

[0067] like Figure 15 As shown, the fully automatic winding device of the present invention further includes the following steps during winding:

[0068] Step 100: The shuttle moving mechanism 24 first drives the shuttle taker 22 to move closer to the shuttle case a located at the front end of the rotating shaft 21, so that the shuttle taker 22 grips the bobbin b inside the shuttle case a. The shuttle moving mechanism 24 then drives the shuttle taker 22 to move away from the shuttle case a located at the front end of the rotating shaft 21, so that the shuttle taker 22 removes the gripped bobbin b from the shuttle case a.

[0069] Step 700: The shuttle-taking moving mechanism 24 first drives the shuttle taker 22 to move closer to the shuttle case a located at the front end of the rotating shaft 21, so that the shuttle taker 22 pushes the gripped shuttle core b into the shuttle case a, and then releases the shuttle core b. The shuttle-taking moving mechanism 24 then drives the shuttle taker 22 to move away from the shuttle case a located at the front end of the rotating shaft 21.

[0070] The installation and removal of the shuttle housing a at the front end of the rotating shaft 21 can be performed manually or by the shuttle changing module.

[0071] Specifically, such as Figure 9 As shown, the winding module 20 further includes an inner shaft tube 25 and an outer shaft tube 26. The inner shaft tube 25 is sleeved on the periphery of the rotating shaft 21, and the outer shaft tube 26 is sleeved on the periphery of the inner shaft tube 25. A limiting post 211 is provided on the periphery of the rotating shaft 21. The inner shaft tube 25 and the outer shaft tube 26 are respectively provided with a strip hole 251 and a fixing hole 261. The limiting post 211 passes through the strip hole 251 of the inner shaft tube 25. 1. The shuttle is inserted into the fixing hole 261 of the outer shaft tube 26, and the strip hole 251 extends axially; the shuttle taker 22 is fixedly disposed at the front end of the inner shaft tube 25, and the shuttle taker moving mechanism 24 is drivenly connected to the rear end of the inner shaft tube 25. When the shuttle taker 22 moves axially along the rotating shaft 21, it can retract and extend out of the front end of the outer shaft tube 26; the winding rotation mechanism 23 is drivenly connected to the rear end of the outer shaft tube 26.

[0072] Since the limiting post 211 and the fixing hole 261 have the same dimensions in both the axial and circumferential directions, the relative positions of the rotating shaft 21 and the outer shaft tube 26 in both the axial and circumferential directions remain fixed. When the winding rotation mechanism 23 drives the outer shaft tube 26 to rotate, the outer shaft tube 26 can drive the rotating shaft 21 to rotate synchronously. Furthermore, since the limiting post 211 and the strip hole 251 have the same dimensions in the circumferential direction, while the strip hole 251 is larger in the axial direction... The size of the limiting post 211 ensures that the relative position of the rotating shaft 21 and the inner shaft tube 25 in the circumferential direction remains fixed, while the inner shaft tube 25 can move relative to the rotating shaft 21 in the axial direction. When the outer shaft tube 26 drives the rotating shaft 21 to rotate synchronously, the rotating shaft 21 can drive the inner shaft tube 25 to rotate synchronously. However, when the shuttle moving mechanism 24 drives the inner shaft tube 25 to move axially, the rotating shaft 21 will not move synchronously with the inner shaft tube 25.

[0073] Preferably, the annular bracket 31 is sleeved on the periphery of the outer shaft tube 26 via a bearing, and the outer shaft tube 26 passes through the mounting plate 10 via a bearing seat.

[0074] The winding rotation mechanism 23 includes a first driving wheel 231, a first driven wheel 232, a first transmission belt 233, and a first drive motor 234. The first driving wheel 231 is coaxially fixed on the rotating shaft 21 of the first drive motor 234, the first driven wheel 232 is coaxially fixed on the rear end of the outer shaft tube 26, and the first transmission belt 233 is sleeved and connected between the first driving wheel 231 and the first driven wheel 232.

[0075] The shuttle moving mechanism 24 includes a first driving cylinder 241, a second driving cylinder 242, and a moving base 243. The first driving cylinder 241 and the second driving cylinder 242 are respectively located on the radial sides of the inner shaft tube 25. One end of the moving base 243 is fixedly connected to the output end of the first driving cylinder 241, and the other end is fixedly connected to the output end of the second driving cylinder 242. The rear end of the inner shaft tube 25 is rotatably connected to the middle of the moving base 243.

[0076] like Figure 8As shown, the wire clamping revolving mechanism 33 includes a second driving wheel 331, a second driven wheel 332, a second transmission belt 333, and a second drive motor 334. The second driving wheel 331 is coaxially fixed on the rotating shaft 21 of the second drive motor 334, and the second driven wheel 332 is coaxially fixed on the annular bracket 31. The second transmission belt 333 is sleeved and connected between the second driving wheel 331 and the second driven wheel 332. The second driven wheel 332 is provided with a plurality of through holes 335, and the base 324 of the wire clamp 32 is connected and fixed to the annular bracket 31 by a plurality of screws 336 passing through the plurality of through holes 335.

[0077] The tangent moving mechanism 42 includes a tangent cylinder, the output end of which is fixedly connected to the connecting part 411 of the cutter 41.

[0078] like Figure 1 As shown, the fully automatic winding device also includes a thread quantity sensing module 50 disposed on the mounting plate 10, used to sense the thickness of the bottom thread c wound on the bobbin b during winding.

[0079] like Figure 10 As shown, the thread sensing module 50 includes a sensing probe 51 and a probe moving mechanism 52. The probe moving mechanism 52 drives the sensing probe 51 to move axially along the rotating shaft 21. The sensing probe 51 includes a telescopic sensor 511, a connecting rod 512, a telescopic spring 513, and an abutting wheel 514. The telescopic sensor 511 is telescopically disposed within the telescopic sensor 511 via the connecting rod 512 and is connected to the telescopic sensor 511 via the telescopic spring 513. The abutting wheel 514 is rotatably disposed on one end of the connecting rod 512 facing the rotating shaft 21. When the sensing probe 51 moves close to the rotating shaft 21, the abutting wheel 514 abuts against the thread c wound inside the bobbin b.

[0080] In step 400, the probe moving mechanism 52 drives the sensing probe 51 to move closer to the bobbin b located on the rotating shaft 21, so that the abutting wheel 514 abuts against the bobbin thread c wound inside the bobbin b. When the shuttle taker 22 drives the bobbin b to rotate and wind the yarn, as the thickness of the bobbin thread c inside the bobbin b increases, the abutting wheel 514, under the action of the bobbin thread c, drives the connecting rod 512 to move and retract towards the telescopic sensor 511. The telescopic sensor 511 calculates the thickness of the bobbin thread c wound on the bobbin b by sensing the amount of retraction of the connecting rod 512. After the winding is completed, the probe moving mechanism 52 drives the sensing probe 51 to move away from the bobbin b located on the rotating shaft 21.

[0081] The probe moving mechanism 52 includes a probe cylinder, the output end of which is fixedly connected to the telescopic sensor 511 of the sensing probe 51.

[0082] Example 2

[0083] As an optimization of Embodiment 1, to avoid the wire clamp 32 protruding from the annular bracket 31 being interfered with by the bottom line c during its revolution, in this embodiment, as follows: Figure 1 and 10 As shown, the fully automatic winding device further includes a wire-picking module 60 disposed on the mounting plate 10, the wire-picking module 60 comprising:

[0084] The cable guide lever 61 and the cable guide moving mechanism 62 are connected to drive the cable guide lever 61 to move. The moving path of the cable guide lever 61 has a first point and a second point. When the cable guide moving mechanism 62 drives the cable guide lever 61 to move to the first point, the cable guide lever 61 is located behind the cable clamp 32. When the cable guide moving mechanism 62 drives the cable guide lever 61 to move to the second point, the cable guide lever 61 is located in front of the cable clamp 32.

[0085] The device includes a wire-pulling arm 63 and a wire-pulling swing mechanism 64. The wire-pulling swing mechanism 64 drives the wire-pulling arm 63 to swing. The swing path of the wire-pulling arm 63 has a fourth position and a fifth position. When the wire-pulling swing mechanism 64 drives the wire-pulling arm 63 to swing to the fourth position, the wire-pulling arm 63 is located outside the outer circumference of the wire clamp 32. When the wire-pulling swing mechanism 64 drives the wire-pulling arm 63 to swing to the fifth position, the wire-pulling arm 63 is located within the inner circumference of the wire clamp 32.

[0086] In this embodiment, the wire-pulling module 60 is located to the right of the winding module 20 and the clamping module 30, that is, on the inlet side of the bottom line c.

[0087] In step 200, before the winding rotation mechanism 23 and the wire clamping revolution mechanism 33 drive the rotating shaft 21, the shuttle taker 22, and the wire clamp 32 to rotate synchronously, as follows: Figure 11-13 and Figure 16As shown, the thread-pulling mechanism 62 first drives the thread-pulling rod 61 to move from the first position to the second position, so as to move the bottom thread c to the front of the thread clamp 32. The thread-pulling swing mechanism 64 then drives the thread-pulling arm 63 to swing from the fourth position to the fifth position, so as to move the end of the bottom thread c near the bobbin b to align with the winding groove of the bobbin b. Until in step 400, when the bottom thread c of a predetermined thickness is wound on the bobbin b, the thread-pulling mechanism 62 drives the thread-pulling rod 61 to move from the second position to the first position, and the thread-pulling swing mechanism 64 then drives the thread-pulling arm 63 to swing from the fifth position to the fourth position, so that the thread-pulling rod 61 and the thread-pulling arm 63 release the bottom thread c.

[0088] Of course, after the thread lever 61 moves the bottom thread c to the front of the thread clamp 32, the winding rotation mechanism 23 and the thread clamping revolution mechanism 33 can first drive the rotating shaft 21, the shuttle taker 22 and the thread clamp 32 to rotate synchronously for a few turns, so as to first wind the bottom thread c around the bobbin b for a few turns, so as to enhance the winding force of the bottom thread c on the bobbin b, so as to avoid the thread end of the bottom thread c from coming out of the thread clamp 32 due to the excessive turning force of the thread lever 63 when the thread lever 63 moves the end of the bottom thread c close to the bobbin b to align with the winding groove of the bobbin b.

[0089] In step 600, before the clamping mechanism 33 continues to drive the clamp 32 to revolve around the rotating axis 21, the thread-pulling mechanism 62 first drives the thread-pulling rod 61 from the first position to the second position to move the bottom thread c to the front of the clamp 32. The thread-pulling swing mechanism 64 then drives the thread-pulling arm 63 to swing from the fourth position to the fifth position to move the end of the bottom thread c near the bobbin b to align with the winding groove of the bobbin b. Only after the bottom thread c is cut does the thread-pulling mechanism 62 drive the thread-pulling rod 61 from the second position to the first position, and the thread-pulling swing mechanism 64 then drives the thread-pulling arm 63 to swing from the fifth position to the fourth position, so that the thread-pulling rod 61 and the thread-pulling arm 63 release the bottom thread c.

[0090] In this embodiment, the moving direction of the wire-pulling lever 61 is not parallel to the axial direction of the rotating shaft 21, but rather at a certain angle to the axial direction of the rotating shaft 21. This allows the wire-pulling lever 61 to be located outside the annular bracket 31 when it moves to the first position, and directly in front of the wire clamp 32 when it moves to the second position. This increases the wire-feeding angle when the bottom thread c is moved to the front of the wire clamp 32, thereby reducing the distance between the wire clamp 32 and the shuttle taker 22.

[0091] Example 3

[0092] Since the thread-pulling arm 63 moves the end of the bottom thread c close to the bobbin b to align with the winding groove of the bobbin b, the distance between the bottom thread c and the thread clamp 32 becomes smaller, making it easier to interfere with the revolution of the thread clamp 32. Therefore, it is necessary to increase the distance between the thread clamp 32 and the shuttle taker 22.

[0093] As an optimization of Embodiment 2, in order not to increase the distance between the wire clamp 32 and the shuttle taker 22, in this embodiment, the moving path of the wire-pulling rod 61 also has a third position. When the wire-pulling moving mechanism 62 drives the wire-pulling rod 61 to move to the third position, the wire-pulling rod 61 is located in front of the wire clamp 32, and the distance between the third position and the wire clamp 32 is greater than the distance between the second position and the wire clamp 32.

[0094] In this embodiment, the third position is added at a greater distance from the second position, and in step 200, after the wire-pulling swing mechanism 64 drives the wire-pulling arm 63 to swing from the fourth position to the fifth position, as follows... Figure 14 and Figure 17 As shown, the thread-pulling mechanism 62 then drives the thread-pulling rod 61 to move from the second position to the third position, so as to move the bottom thread c further forward from the thread clamp 32; until in step 400, when the bottom thread c of a predetermined thickness is wound on the bobbin b, the thread-pulling mechanism 62 drives the thread-pulling rod 61 to move from the third position to the first position, and the thread-pulling swing mechanism 64 then drives the thread-pulling arm 63 to swing from the fifth position to the fourth position, so that the thread-pulling rod 61 and the thread-pulling arm 63 release the bottom thread c.

[0095] When the wire lever 61 is located at the third position, the bottom line c is moved further forward from the wire clamp 32, resulting in a larger wire entry angle and a greater distance from the wire clamp 32. This reduces the distance between the wire clamp 32 and the shuttle taker 22.

[0096] Similarly, in step 600, before the thread clamping mechanism 33 continues to drive the thread clamp 32 to revolve around the rotating axis 21, the thread-pulling mechanism 62 first drives the thread-pulling rod 61 to move from the first position to the second position, so as to move the bottom thread c to the front of the thread clamp 32. Then, the thread-pulling swing mechanism 64 drives the thread-pulling arm 63 to swing from the fourth position to the fifth position, so as to move the end of the bottom thread c near the bobbin b to be wound with the bobbin b. After the slots are aligned, the thread-pulling mechanism 62 drives the thread-pulling lever 61 to move from the second position to the third position, so as to move the bottom thread c further forward of the thread clamp 32; until the bottom thread c is cut, the thread-pulling mechanism 62 drives the thread-pulling lever 61 to move from the third position to the first position, and the thread-pulling swing mechanism 64 drives the thread-pulling arm 63 to swing from the fifth position to the fourth position, so that the thread-pulling lever 61 and the thread-pulling arm 63 release the bottom thread c.
