Description

Technical Field

[0001] The invention relates to sewing machine technology, and in particular to a full-automatic winding device and a winding method. Background Art

[0002] A sewing machine is a machine that uses one or more bobbin threads to form one or more stitches on the fabric to interweave or sew one or more layers of fabric together.

[0003] The existing sewing machine generally has a rotary hook device under the needle plate, in which a bobbin is arranged, and the bobbin is wound with a bottom thread to cooperate with the surface thread on the machine head needle to complete the sewing of the fabric. However, the sewing machine usually works non-stop, and the amount of thread on the bobbin is limited. Therefore, in order to meet the continuous working requirements of the sewing machine, the bobbin in the rotary hook device needs to be constantly replaced during the operation of the sewing machine.

[0004] During the shuttle changing process, the replaced bobbin needs to be wound with a new bottom line. At this time, the bobbin needs to be hooked and wound manually, which is inefficient. Summary of the invention

[0005] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a fully automatic winding device and a winding method, which 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 solutions: A fully automatic winding device comprises a mounting plate and a winding module, a wire clamping module and a wire cutting module arranged on the mounting plate. The winding module comprises a rotating shaft, a shuttle taker and a winding self-rotating mechanism, wherein the shuttle taker is sleeved on the periphery of the rotating shaft, and the winding self-rotating mechanism is connected to drive the rotating shaft and the shuttle taker to rotate synchronously; The thread clamp module includes an annular bracket, a thread clamp and a thread clamp revolution mechanism, wherein the annular bracket surrounds the periphery of the shuttle taker, the thread clamp is arranged on the periphery of the annular bracket, and the thread clamp revolution mechanism is connected to drive the annular bracket to rotate, thereby driving the thread clamp to revolve around the rotation axis; The wire cutting module comprises a cutter and a wire cutting moving mechanism, wherein the wire cutting moving mechanism is connected to drive the cutter to move radially along the rotating shaft, wherein the cutter comprises a wire cutting platform and a cutter head, wherein the blade of the cutter head faces the direction opposite to the revolution of the wire clamp, and when the cutter moves close to the rotating shaft, the cutter head is located within the inner circumference of the revolution of the wire clamp, and when the cutter moves away from the rotating shaft, the cutter head is located outside the outer circumference of the revolution of the wire clamp; A wire cutting platform is provided on the inner side of the wire clamp, and a wire clamping opening is provided on the outer side of the wire clamp; when the cutter moves close to the rotating shaft and the wire clamp revolves to the side facing the cutter, the cutter head is fitted with the wire cutting platform.

[0007] Furthermore, the thread clamp is protruding forward on the periphery of the annular bracket so that the thread clamping port is aligned with the winding groove of the bobbin located in front of the shuttle taker; the connecting portion and the cutter head of the cutter are perpendicular to each other, wherein the connecting portion is located in front of the thread clamp and the cutter head is extended backward.

[0008] Furthermore, the wire clamp includes a baffle, a base and a wire clamping spring, the baffle and the base are arranged relative to each other front and back, the wire cutting table is connected to the inner side between the baffle and the base, the wire clamping port is located on the outer side between the baffle and the base, and the wire clamping spring is arranged in the wire clamping port.

[0009] Furthermore, the winding module also includes a shuttle-taking moving mechanism, which is connected to drive the shuttle-taking device to move axially along the rotating shaft.

[0010] Furthermore, the fully automatic winding device also includes a wire dialing module arranged on the mounting plate, and the wire dialing module includes: A wire-driving rod and a wire-driving moving mechanism, wherein the wire-driving moving mechanism is connected to drive the wire-driving rod to move, and when the wire-driving moving mechanism drives the wire-driving rod to move to a first position, the wire-driving rod is located behind the wire clamp, and when the wire-driving moving mechanism drives the wire-driving rod to move to a second position, the wire-driving rod is located in front of the wire clamp; A wire-driving arm and a wire-driving swing mechanism, wherein the wire-driving swing mechanism is connected to drive the wire-driving arm to swing, and when the wire-driving swing mechanism drives the wire-driving arm to swing to a fourth position, the wire-driving arm is located within the inner circumference of the revolution of the wire clamp, and when the wire-driving swing mechanism drives the wire-driving arm to swing to a fifth position, the wire-driving arm is located outside the outer circumference of the revolution of the wire clamp.

[0011] Furthermore, the moving path of the wire driving rod also has a third position. When the wire driving moving mechanism drives the wire driving rod to move to the third position, the wire driving rod 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.

[0012] A winding method comprises the following steps: Step 200: The winding rotation mechanism and the thread clamp revolution mechanism respectively drive the rotating shaft, the shuttle taker and the thread clamp to rotate synchronously to wind a predetermined number of turns of the bottom thread on the bobbin; Step 300: the winding rotation mechanism stops driving the rotating shaft and the shuttle taker to rotate, and the thread clamping revolution mechanism continues to drive the thread clamp to revolve around the rotating shaft, so that all the thread ends clamped in the thread clamp are wound around the bobbin; Step 400: the thread clamp revolution mechanism stops driving the thread clamp to revolve around the rotation axis, and the thread winding rotation mechanism continues to drive the rotation axis and the shuttle taker to rotate synchronously, so as to wind the bobbin thread of a predetermined thickness on the bobbin; Step 500: the thread winding self-rotating mechanism stops driving the rotating shaft and the shuttle taker to rotate, and the thread cutting moving mechanism drives the cutter to move closer to the rotating shaft; Step 600: The thread clamp revolution mechanism continues to drive the thread clamp to revolve around the rotation axis so that the thread clamp passes through the bottom thread and the cutter in sequence. When the thread clamp passes through the bottom thread, the thread clamp hooks the bottom thread into its thread clamping mouth. When the thread clamp passes through the cutter, its thread cutting table cooperates with the knife head to cut off the bottom thread between the shuttle core and the thread clamp.

[0013] Furthermore, the winding method further comprises the following steps: Step 100: The shuttle taking moving mechanism first drives the shuttle taking device to move closer to the bobbin case located at the front end of the rotating shaft, so that the shuttle taking device can grasp the bobbin in the bobbin case, and then the shuttle taking moving mechanism drives the shuttle taking device to move away from the bobbin case located at the front end of the rotating shaft, so that the shuttle taking device can take the grasped bobbin out of the bobbin case; Step 700: The shuttle moving mechanism first drives the shuttle taker to move closer to the bobbin case at the front end of the rotating shaft, so that the shuttle taker pushes the grasped bobbin into the bobbin case, and then releases the bobbin. The shuttle moving mechanism then drives the shuttle taker to move away from the bobbin case at the front end of the rotating shaft.

[0014] Furthermore, in step 200, before the wire winding rotation mechanism and the wire clamping revolution mechanism respectively drive the rotating shaft, the shuttle taker and the wire clamp to rotate synchronously, the wire moving mechanism first drives the wire shifting rod to move from the first position to the second position to move the bottom line to the front of the wire clamp, and the wire shifting swing mechanism then drives the wire shifting arm to swing from the fourth position to the fifth position to move the end of the bottom line close to the bobbin to be aligned with the winding groove of the bobbin.

[0015] Further, in step 200, after the wire-driving swinging mechanism drives the wire-driving arm to swing from the fourth position to the fifth position, the wire-driving moving mechanism drives the wire-driving rod to move from the second position to the third position to move the bottom line to the front farther from the wire clamp.

[0016] The present invention has the following beneficial effects: the fully automatic winding device of the present invention can automatically complete winding processes such as bobbin grabbing, bottom line winding and bottom line cutting through the mutually coordinated winding module, wire clamping module and wire cutting module, and through the mutual cooperation of the wire clamp and the cutter, the wire clamp can hook the bottom line into its wire clamping mouth during revolution, and cooperate with the cutter to cut the bottom line to form the thread tail of the previous bobbin and the thread head of the next bobbin respectively, which not only improves the efficiency of thread hooking and thread cutting, but also does not require a special threading module, and simplifies the equipment structure.

[0031] Embodiment 1 like Figure 1 and 2 As shown, a fully automatic winding device includes a mounting plate 10 and a winding module 20, a clamping module 30 and a cutting module 40 arranged on the mounting plate 10. The winding module 20 includes a rotating shaft 21, a shuttle taking device 22 and a winding self-rotation mechanism 23. The shuttle taking device 22 is sleeved on the outer periphery of the rotating shaft 21. The winding self-rotation mechanism 23 is connected to drive the rotating shaft 21 and the shuttle taking device 22 to rotate synchronously. The thread clamp module 30 includes an annular bracket 31, a thread clamp 32 and a thread clamp revolution mechanism 33. The annular bracket 31 surrounds the outer periphery of the shuttle taker 22, and the thread clamp 32 is arranged on the outer periphery of the annular bracket 31. The thread clamp revolution mechanism 33 is connected to drive the annular bracket 31 to rotate, thereby driving the thread clamp 32 to revolve around the rotating shaft 21. The wire cutting module 40 includes a cutter 41 and a wire cutting moving mechanism 42. The wire cutting moving mechanism 42 is connected to drive the cutter 41 to move radially along the rotating shaft 21. The cutter 41 includes a connecting portion 411 and a cutter head 412. The blade 413 of the cutter head 412 faces the direction opposite to the revolution of the wire clamp 32. When the cutter 41 moves close to the rotating shaft 21, the cutter head 412 is located within the inner circumference of the revolution of the wire clamp 32. When the cutter 41 moves away from the rotating shaft 21, the cutter head 412 is located outside the outer circumference of the revolution of the wire clamp 32. A wire cutting platform 321 is provided on the inner side of the wire clamp 32 , and a wire clamping opening 322 is provided on the outer side of the wire clamp 32 ; 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 fits against the wire cutting platform 321 .

[0032] The fully automatic winding device of the present invention can automatically complete winding processes such as bobbin grabbing, bottom line winding and bottom line cutting through the mutually coordinated winding module 20, thread clamping module 30 and thread cutting module 40, and through the mutual cooperation of the thread clamp 32 and the cutter 41, the thread clamp 32 can hook the bottom line c into its thread clamping mouth 322 during revolution, and cooperate with the cutter 41 to cut the bottom line to form the thread tail of the previous bobbin b and the thread head of the next bobbin b respectively, which not only improves the efficiency of thread hooking and thread cutting, but also does not require a special threading module, and simplifies the equipment structure.

[0033] For the sake of convenience of explanation, the present invention defines the side of the clamp 32 facing the rotating shaft 21 as the inner side of the clamp 32, and defines the side of the clamp 32 facing away from the rotating shaft 21 as the outer side of the clamp 32. The circumference of the inner side of the clamp 32 during the revolution is the inner circumference of the revolution of the clamp 32, and the circumference of the outer side of the clamp 32 during the revolution is the outer circumference of the revolution of the clamp 32.

[0034] like Fig.15 As shown, the fully automatic winding device of the present invention comprises the following steps when winding: Step 200: The winding rotation mechanism 23 and the thread clamp revolution mechanism 33 respectively drive the rotating shaft 21, the shuttle taker 22 and the thread clamp 32 to rotate synchronously (the rotating shaft 21 and the shuttle taker 22 rotate, and the thread clamp 32 revolves, and the three have the same angular velocity) to wind a predetermined number of turns of the bottom thread c on the bobbin b; Step 300: the thread winding rotation mechanism 23 stops driving the rotating shaft 21 and the shuttle taking device 22 to rotate, and the thread clamping revolution mechanism 33 continues to drive the thread clamping device 32 to revolve around the rotating shaft 21, so that all the thread ends clamped in the thread clamping device 32 are wound around the shuttle core b; Step 400: the thread clamp revolution mechanism 33 stops driving the thread clamp 32 to revolve around the rotating shaft 21, and the thread winding rotation mechanism 23 continues to drive the rotating shaft 21 and the shuttle taker 22 to rotate synchronously, so as to wind the bottom thread c of a predetermined thickness on the bobbin b; Step 500: the thread winding self-rotation mechanism 23 stops driving the rotating shaft 21 and the shuttle taking device 22 to rotate, and the thread cutting movement mechanism 42 drives the cutter 41 to move closer to the rotating shaft 21; Step 600: The thread clamp revolution mechanism 33 continues to drive the thread clamp 32 to revolve around the rotating shaft 21, so that the thread clamp 32 passes through the bottom line c and the cutter 41 in sequence. When passing through the bottom line c, the thread clamp 32 hooks the bottom line c into its thread clamping opening 322. When passing through the cutter 41, the thread cutting table 321 of the thread clamp 32 cooperates with the knife head 412 to cut off the bottom line between the bobbin b and the thread clamp 32.

[0035] When the bottom line c between the bobbin b and the thread clamp 32 is cut off, the bottom line c remaining in the bobbin b and the bottom line c remaining in the thread clamp 32 respectively form the thread tail of the previous bobbin b and the thread head of the next bobbin b. In this way, except for the first bobbin b which needs to be manually hooked, the remaining bobbin b can synchronously complete the thread hooking and thread cutting processes through the revolution of the thread clamp 32 in step 600, which greatly improves the efficiency of thread hooking and thread cutting.

[0036] In this embodiment, the rotating shaft 21 and the shuttle taker 22 rotate clockwise, and the thread clamp 32 revolves clockwise. The thread cutting module 40 is located below the winding module 20 and the thread clamping module 30, and the blade 413 of the cutter 41 faces the right side, and the bottom line c enters from the right side of the winding module 20 when winding.

[0037] At the end of step 500, if Figure 3As shown, the clamp 32 stays above the rotating shaft 21, and the cutter head 412 moves from outside the outer circumference of the revolution of the clamp 32 to inside the inner circumference of the revolution of the clamp 32. In step 600, as Figure 4 As shown, the thread clamp 32 revolves clockwise from the top of the rotating shaft 21 to the left side of the cutter 41, and the thread clamp 32 hooks the bottom line c into its thread clamping opening 322 when revolving to the right side of the rotating shaft 21. Figure 5 As described above, when the thread clamp 32 revolves to the right side of the cutter 41, the bottom line c is pulled down to the bottom of the cutter head 412. Figure 6 As shown, when the thread clamp 32 revolves to the bottom of the rotating shaft 21, the thread cutting table 321 cooperates with the cutter head 412 to cut the bottom line c from the left and right sides respectively. Figure 7 As shown, when the thread clamp 32 revolves to the left side of the cutter 41 , the cutter head 412 moves from within the revolving inner circumference of the thread clamp 32 to outside the revolving outer circumference of the thread clamp 32 .

[0038] like Figure 8 As shown, the thread clamp 32 is protruding forward on the periphery of the annular bracket 31, so that the thread clamping opening 322 is aligned with the winding groove of the bobbin b located in front of the shuttle taker 22. The thread clamp 32 includes a baffle 323, a base 324 and a thread clamping spring 325, the baffle 323 and the base 324 are arranged front and back oppositely, the thread cutting table 321 is connected to the inner side between the baffle 323 and the base 324, the thread clamping opening 322 is located on the outer side between the baffle 323 and the base 324, and the thread clamping spring 325 is arranged in the thread clamping opening 322.

[0039] Preferably, on the inner side, the base 324, the baffle 323 and the tangent table 321 are flush with each other to form an arc concave surface that can fit with the cutter head 412, and on the outer side and the two sides adjacent to the outer side, the tangent table 321 is retracted by about 2-5 mm compared to the base 324 and the baffle 323 to form a U-shaped hook or C-shaped hook-shaped wire clamping opening 322, so as to hook the bottom line c in step 600.

[0040] The connecting portion 411 and the blade head 412 of the cutter 41 are perpendicular to each other, wherein the connecting portion 411 is located in front of the wire clamp 32, and the blade head 412 is extended backward to prevent the raised cutter 41 from interfering with the protruding wire clamp 32 during its revolution.

[0041] In this embodiment, the shuttle taking device 22 includes an annular electromagnet, which can generate magnetic force when powered on to grasp the shuttle core b by magnetic attraction, and lose the magnetic force when powered off to release the shuttle core b.

[0042] like Figure 2 As shown, the winding module 20 further includes a shuttle-taking moving mechanism 24 , and the shuttle-taking moving mechanism 24 is connected to drive the shuttle-taking device 22 to move axially along the rotating shaft 21 .

[0043] like Fig.15 As shown, the fully automatic winding device of the present invention also includes the following steps when winding: Step 100: The shuttle taking moving mechanism 24 first drives the shuttle taking device 22 to move closer to the bobbin case a located at the front end of the rotating shaft 21, so that the shuttle taking device 22 can grasp the bobbin core b in the bobbin case a, and then the shuttle taking moving mechanism 24 drives the shuttle taking device 22 to move away from the bobbin case a located at the front end of the rotating shaft 21, so that the shuttle taking device 22 can take the grasped bobbin core b out of the bobbin case a; Step 700: The shuttle moving mechanism 24 first drives the shuttle taking device 22 to move close to the bobbin case a located at the front end of the rotating shaft 21, so that the shuttle taking device 22 pushes the grasped bobbin core b into the bobbin case a, and then releases the bobbin core b. The shuttle moving mechanism 24 then drives the shuttle taking device 22 to move away from the bobbin case a located at the front end of the rotating shaft 21.

[0044] The installation and removal of the bobbin case a at the front end of the rotating shaft 21 can be performed manually or by a shuttle changing module.

[0045] Specifically, Fig. 9 As shown, the winding module 20 also includes an inner layer shaft tube 25 and an outer layer shaft tube 26, the inner layer shaft tube 25 is sleeved on the periphery of the rotating shaft 21, and the outer layer shaft tube 26 is sleeved on the periphery of the inner layer shaft tube 25; a limiting column 211 is provided on the periphery of the rotating shaft 21, and a strip hole 251 and a fixing hole 261 are respectively provided on the inner layer shaft tube 25 and the outer layer shaft tube 26, and the limiting column 211 passes through the strip hole 251 of the inner layer shaft tube 25. 1 is inserted into the fixing hole 261 of the outer layer shaft tube 26, and the strip hole 251 extends in the axial direction; the shuttle taking device 22 is fixedly arranged at the front end of the inner layer shaft tube 25, and the shuttle taking moving mechanism 24 is transmission-connected to the rear end of the inner layer shaft tube 25. When the shuttle taking device 22 moves along the axial direction of the rotating shaft 21, it can be retracted and extended out of the front end of the outer layer shaft tube 26; the winding self-rotation mechanism 23 is transmission-connected to the rear end of the outer layer shaft tube 26.

[0046] Since the sizes of the limiting column 211 and the fixing hole 261 in the axial and circumferential directions are the same, the relative positions of the rotating shaft 21 and the outer layer shaft tube 26 in the axial and circumferential directions are fixed. When the winding rotation mechanism 23 drives the outer layer shaft tube 26 to rotate, the outer layer shaft tube 26 can drive the rotating shaft 21 to rotate synchronously. Since the sizes of the limiting column 211 and the strip hole 251 in the circumferential direction are the same, and the size of the strip hole 251 in the axial direction is larger than that in the circumferential direction, the relative positions of the rotating shaft 21 and the outer layer shaft tube 26 in the axial and circumferential directions are fixed. Due to the size of the limiting column 211, the relative position between the rotating shaft 21 and the inner shaft tube 25 in the circumferential direction is 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. 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.

[0047] Preferably, the annular bracket 31 is sleeved on the periphery of the outer layer shaft tube 26 through a bearing sleeve, and the outer layer shaft tube 26 is penetrated into the mounting plate 10 through a bearing seat.

[0048] The winding and rotating mechanism 23 includes a first driving wheel 231, a first driven wheel 232, a first transmission belt 233 and a first driving motor 234. The first driving wheel 231 is coaxially fixed to the rotating shaft 21 of the first driving motor 234, the first driven wheel 232 is coaxially fixed to the rear end of the outer layer 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.

[0049] The shuttle-taking moving mechanism 24 includes a first driving cylinder 241, a second driving cylinder 242 and a moving seat 243. The first driving cylinder 241 and the second driving cylinder 242 are respectively located on both sides of the radial direction of the inner layer shaft tube 25; one end of the moving seat 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 layer shaft tube 25 is rotatably connected to the middle of the moving seat 243.

[0050] like Figure 8As shown, the wire clamp revolution 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 to the rotating shaft 21 of the second drive motor 334, the second driven wheel 332 is coaxially fixed to the annular bracket 31, and 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 penetrated through the plurality of through holes 335.

[0051] The tangent moving mechanism 42 includes a tangent cylinder, and an output end of the tangent cylinder is fixedly connected to the connecting portion 411 of the cutter 41 .

[0052] like Figure 1 As shown, the fully automatic winding device further includes a thread quantity sensing module 50 disposed on the mounting plate 10 for sensing the thickness of the bottom thread c wound on the bobbin b during winding.

[0053] like Fig.10 As shown, the line quantity sensing module 50 includes a sensing probe 51 and a probe moving mechanism 52, the probe moving mechanism 52 is connected to drive 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 abutment wheel 514, the telescopic sensor 511 is telescopically arranged in the telescopic sensor 511 through the connecting rod 512, and is connected to the telescopic sensor 511 through the telescopic spring 513; the abutment wheel 514 is rotatably arranged on one end of the connecting rod 512 facing the rotating shaft 21, and when the sensing probe 51 moves close to the rotating shaft 21, the abutment wheel 514 abuts against the bottom line c wound in the bobbin b.

[0054] In step 400, the probe moving mechanism 52 drives the sensing probe 51 to move close to the bobbin b located on the rotating shaft 21, so that the abutment wheel 514 abuts against the bottom line c wound in the bobbin b. When the shuttle taker 22 drives the bobbin b to rotate and wind, as the thickness of the bottom line c in the bobbin b increases, the abutment wheel 514 drives the connecting rod 512 to move and retract toward the telescopic sensor 511 under the action of the bottom line c. The telescopic sensor 511 calculates the thickness of the bottom line c wound on the bobbin b by sensing the retraction amount of the connecting rod 512. After winding, the probe moving mechanism 52 drives the sensing probe 51 to move away from the bobbin b located on the rotating shaft 21.

[0055] The probe moving mechanism 52 includes a probe cylinder, and an output end of the probe cylinder is fixedly connected to the telescopic sensor 511 of the sensing probe 51 .

[0056] Embodiment 2 As an optimization solution of the first embodiment, in order to prevent the clamp 32 protruding from the annular support 31 from being disturbed by the bottom line c during its revolution, in this embodiment, Figure 1 and 10 As shown, the fully automatic winding device also includes a wire dialing module 60 arranged on the mounting plate 10, and the wire dialing module 60 includes: A wire-driving rod 61 and a wire-driving moving mechanism 62, wherein the wire-driving moving mechanism 62 is connected to drive the wire-driving rod 61 to move, and the moving path of the wire-driving rod 61 has a first position and a second position. When the wire-driving moving mechanism 62 drives the wire-driving rod 61 to move to the first position, the wire-driving rod 61 is located behind the wire clamp 32, and when the wire-driving moving mechanism 62 drives the wire-driving rod 61 to move to the second position, the wire-driving rod 61 is located in front of the wire clamp 32; The wire-driving arm 63 and the wire-driving swinging mechanism 64 are connected to drive the wire-driving arm 63 to swing, and the swinging path of the wire-driving arm 63 has a fourth position and a fifth position. When the wire-driving swinging mechanism 64 drives the wire-driving arm 63 to swing to the fourth position, the wire-driving arm 63 is located outside the outer circumference of the revolution of the wire clamp 32, and when the wire-driving swinging mechanism 64 drives the wire-driving arm 63 to swing to the fifth position, the wire-driving arm 63 is located within the inner circumference of the revolution of the wire clamp 32.

[0057] In this embodiment, the wire dialing module 60 is located on the right side of the wire winding module 20 and the wire clamping module 30, that is, on the incoming side of the bottom line c.

[0058] In step 200, before the winding self-rotation mechanism 23 and the clamping revolution mechanism 33 drive the rotating shaft 21, the shuttle taking device 22 and the clamping device 32 to rotate synchronously, Figure 11-13 and Fig.16As shown, the thread moving mechanism 62 first drives the thread moving rod 61 to move from the first position to the second position to move the bottom line c to the front of the thread clamp 32, and the thread moving mechanism 64 then drives the thread moving arm 63 to swing from the fourth position to the fifth position to move the end of the bottom line c close to the bobbin b to be aligned with the winding groove of the bobbin b; until in step 400, when the bottom line c of a predetermined thickness is wound on the bobbin b, the thread moving mechanism 62 drives the thread moving rod 61 to move from the second position to the first position, and the thread moving mechanism 64 then drives the thread moving arm 63 to swing from the fifth position to the fourth position, so that the thread moving rod 61 and the thread moving arm 63 release the bottom line c.

[0059] Of course, after the thread shifting rod 61 shifts the bottom line c to the front of the thread clamp 32, the thread winding rotation mechanism 23 and the thread clamp revolution mechanism 33 can first drive the rotating shaft 21, the shuttle taker 22 and the thread clamp 32 to rotate synchronously for several circles, so as to first wind several circles of the bottom line c on the bobbin b, so as to enhance the winding force of the bottom line c on the bobbin b, so as to avoid the thread end of the bottom line c from escaping from the thread clamp 32 due to the excessive shifting force of the thread shifting arm 63 when the thread shifting arm 63 shifts the end of the bottom line c close to the bobbin b to align with the winding groove of the bobbin b.

[0060] In step 600, before the thread clamp revolution mechanism 33 continues to drive the thread clamp 32 to revolve around the rotating shaft 21, the thread shifting moving mechanism 62 first drives the thread shifting rod 61 to move from the first position to the second position to shift the bottom line c to the front of the thread clamp 32, and the thread shifting swing mechanism 64 then drives the thread shifting arm 63 to swing from the fourth position to the fifth position to shift the end of the bottom line c close to the bobbin b to align with the winding groove of the bobbin b; until the bottom line c is cut off, the thread shifting moving mechanism 62 drives the thread shifting rod 61 to move from the second position to the first position, and the thread shifting swing mechanism 64 then drives the thread shifting arm 63 to swing from the fifth position to the fourth position, so that the thread shifting rod 61 and the thread shifting arm 63 release the bottom line c.

[0061] In this embodiment, the moving direction of the thread shifting rod 61 is not parallel to the axial direction of the rotating shaft 21, but is inclined at a certain angle to the axial direction of the rotating shaft 21, so that when the thread shifting rod 61 moves to the first position, it is located outside the annular bracket 31, and when it moves to the second position, it is located directly in front of the thread clamp 32, so as to increase the thread entry angle when the bottom line c is moved to the front of the thread clamp 32, thereby reducing the distance between the thread clamp 32 and the shuttle taker 22.

[0062] Embodiment 3 After the thread moving arm 63 moves the end of the bottom line c close to the bobbin b to be aligned with the winding groove of the bobbin b, the distance between the bottom line c and the thread clamp 32 becomes smaller, which is more likely to interfere with the revolution of the thread clamp 32, and therefore the distance between the thread clamp 32 and the shuttle taker 22 needs to be increased.

[0063] As an optimization scheme of Example 2, in order not to increase the distance between the thread clamp 32 and the shuttle picker 22, in this embodiment, the moving path of the thread shifting rod 61 also has a third position. When the thread shifting moving mechanism 62 drives the thread shifting rod 61 to move to the third position, the thread shifting rod 61 is located in front of the thread clamp 32, and the distance between the third position and the thread clamp 32 is greater than the distance between the second position and the thread clamp 32.

[0064] In this embodiment, the third position is further away from the second position, and in step 200, after the wire-drying swing mechanism 64 drives the wire-drying arm 63 to swing from the fourth position to the fifth position, Fig.14 and Fig.17 As shown, the thread moving mechanism 62 then drives the thread moving rod 61 to move from the second position to the third position to move the bottom thread c to the front farther away 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 moving mechanism 62 drives the thread moving rod 61 to move from the third position to the first position, and the thread swinging mechanism 64 then drives the thread moving arm 63 to swing from the fifth position to the fourth position, so that the thread moving rod 61 and the thread swinging arm 63 release the bottom thread c.

[0065] When the thread shifting lever 61 is located at the third position, the bottom line c is shifted to a position farther forward from the thread clamp 32, having a larger thread entry angle and a distance farther from the thread clamp 32, thereby shortening the distance between the thread clamp 32 and the shuttle taker 22.

[0066] Similarly, in step 600, before the thread clamp revolution mechanism 33 continues to drive the thread clamp 32 to revolve around the rotating shaft 21, the thread shifting movement mechanism 62 first drives the thread shifting rod 61 to move from the first position to the second position to shift the bottom line c to the front of the thread clamp 32, and the thread shifting swing mechanism 64 then drives the thread shifting arm 63 to swing from the fourth position to the fifth position to shift the end of the bottom line c close to the bobbin b to the winding line of the bobbin b. The grooves are aligned, the wire-digging moving mechanism 62 then drives the wire-digging rod 61 to move from the second position to the third position, so as to move the bottom line c to a farther front of the wire clamp 32; until the bottom line c is cut off, the wire-digging moving mechanism 62 drives the wire-digging rod 61 to move from the third position to the first position, and the wire-digging swinging mechanism 64 then drives the wire-digging arm 63 to swing from the fifth position to the fourth position, so that the wire-digging rod 61 and the wire-digging arm 63 release the bottom line c.
