Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade production and processing technology, specifically to a wire winding machine for wind turbine blade bolt sleeves. Background Technology

[0002] A wind turbine is a power generation device that converts wind energy into mechanical energy and then into electrical energy through blades. The blade is a key component of the wind turbine, and high-strength bolt sleeves are typically embedded in the end face of the blade root, connecting the wind turbine blade and the hub together. To enhance the strength of the bolt sleeve embedded in the blade, fiberglass filaments are wound around the surface of the bolt sleeve. Current technology uses an automatic winding method to wind the bolt sleeve. The winding assembly has clamps that hold and drive the beginning of the fiberglass filaments, winding and fixing them around the bolt sleeve several times. Then, a wire feeding assembly slides along the length of the bolt sleeve, feeding the fiberglass filaments to the surface of the bolt sleeve to facilitate uniform winding. The fiberglass filaments are pressed against the beginning of the winding to prevent them from loosening. Afterward, the clamps release the head of the fiberglass filaments, and the bolt sleeve rotates to wind the filaments. However, in practice, it has been found that the beginning of the fiberglass filaments is thrown off as the bolt sleeve rotates, failing to effectively hold the beginning of the fiberglass filaments in place. At the same time, when the wire feeding assembly slides to one end of the bolt sleeve, the glass fiber is actually only wrapped around the middle of the bolt sleeve. At this time, the wire feeding assembly begins to slide to the other end of the bolt sleeve, and the glass fiber will slide to the right. This prevents the glass fiber from moving horizontally to the end of the bolt sleeve, resulting in the glass fiber at both ends of the bolt sleeve being too thin or not being wrapped at all, thus affecting the winding quality of the glass fiber. Utility Model Content

[0003] The purpose of this invention is to provide a wire winding machine for wind turbine blade bolt sleeves. This machine allows the ends of the fiberglass filaments to be close to or attached to the bolt sleeve, making it easier for the fiberglass filaments to be wound later.

A second slider that cooperates with the second slide rail is fixedly connected to the bottom side of the second slide block.

[0015] The beneficial effects of this utility model are:

[0016] In the above technical solution, the fixed-line clamp and the rotating shaft are coaxially arranged, and the first driving unit drives the fixed-line clamp and the rotating shaft to rotate simultaneously. When the fixed-line clamp clamps the end of the fiberglass filament and rotates with the rotating shaft, the fixed-line clamp and the bolt sleeve are relatively stationary. In this way, when the bolt sleeve rotates relative to the fiberglass filament, it winds and fixes the fiberglass filament on the bolt sleeve. At the same time, the wire feeding assembly reciprocates locally along the axis of the bolt sleeve, which allows the fiberglass filament to be wound later to quickly cover and press down the previously wound fiberglass filament, thereby preventing the end of the fiberglass filament from loosening. Then, the fixed-line clamp releases the end of the fiberglass filament and at the same time, the nozzle blows high-pressure air onto the end of the fiberglass filament on the bolt sleeve, causing the end of the fiberglass filament to bend and tilt to prevent it from being thrown off the bolt sleeve by centrifugal force, and also making it easier for the end of the fiberglass filament to be pressed firmly under the wound fiberglass filament.

[0017] The fiber feeding assembly includes a first slide table that slides along the length of the bolt sleeve to facilitate the even winding of glass fiber filaments onto the surface of the bolt sleeve. A first slide block is provided on the first slide table, and the glass fiber filaments are wound onto the bolt sleeve after passing through the first slide block. When the bolt sleeve rotates and the fiber is wound, the first slide block extends to directly above the bolt sleeve to feed the fiber. At this time, the distance between the first slide block and the bolt sleeve is the shortest. Thus, during the reciprocating sliding of the first slide block with the first slide table, the glass fiber filaments between the first slide block end and the bolt sleeve are always in a basically vertical state, minimizing the horizontal positional difference between the glass fiber filaments at the first slide block end and the bolt sleeve end. When the first slide block moves to the end of the bolt sleeve, the glass fiber filaments follow the movement and are wound onto the end of the bolt sleeve, thereby effectively improving the problem of uneven winding at the end of the bolt sleeve surface.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0034] like Figures 1 to 13As shown, the wire winding machine for wind turbine blade bolt sleeves includes a frame 1, on which a rotating wire winding assembly 2, a wire feeding assembly, a knotting assembly 5 and a feeding assembly 4 are rotatably mounted. The feeding assembly 4 feeds the bolt sleeve 3 to the rotating wire winding assembly 2. The rotating winding assembly 2 includes a rotating shaft 21 and a telescopic shaft 24. The telescopic shaft 24 is coaxially arranged on the opposite side of the rotating shaft 21. The bolt sleeve 3 is fixed between the rotating shaft 21 and the telescopic shaft 24. The rotating shaft 21 drives the bolt sleeve 3 to rotate and wind the fiber. A wire clamp 71 is movably arranged on the rotating shaft 21. The wire clamp 71 extends from the rotating shaft 21 to the upper surface of the bolt sleeve 3 and clamps the beginning of the fiberglass wire. Then, the rotating shaft 21 drives the wire clamp 71 and the bolt sleeve 3 to start rotating and wind the fiberglass wire onto the bolt sleeve 3. The wire feeding assembly drives the fiberglass wire to reciprocate and wind on the bolt sleeve, so that the fiberglass wire wound later presses down the previously wound fiberglass wire to prevent it from loosening and unraveling. Then, the wire clamp 71 releases the end of the fiberglass wire and retracts back to its original position. The rotating shaft 21 drives the bolt sleeve 3 to accelerate and start winding. The rotating winding assembly 2 also includes a nozzle 72. The nozzle 73 blows high-pressure air towards the bolt sleeve 3 to bend and tilt the end of the glass fiber filament towards the surface of the bolt sleeve or to prevent it from being thrown off the bolt sleeve by centrifugal force. This facilitates the reciprocating movement of the wound glass fiber filament to press the end firmly under the wound glass fiber filament.

[0035] The fiber feeding assembly includes a first slide table 6. A first lead screw 11 and a second slide rail 12 are provided on the frame 1. The first lead screw 11 and the second slide rail 12 are along the axial direction of the bolt sleeve 3. A first sliding sleeve 601 and a first slider 602 are fixedly connected to the bottom of the first slide table 6. The first sliding sleeve 601 is slidably disposed on the first lead screw 11, and the first slider 602 is disposed on the second slide rail 12. The first lead screw 11 is connected to a thirteenth drive unit 13, which drives the first lead screw 11 to rotate, thereby driving the first sliding sleeve 601 to slide on the first lead screw 11. That is, the first slide table 6 moves along the axial direction of the bolt sleeve on the frame 1. A first slide block 61 is provided on the side of the first slide table 6 near the bolt sleeve 3. When the bolt sleeve 3 rotates and winds the fiber, the first slide block 61 extends to directly above the bolt sleeve 3. The fiberglass filament is fed out from the first slide block 61 and wound onto the bolt sleeve 3. At this time, the distance between the first slide block 61 and the bolt sleeve 3 is the shortest. Thus, the first slide block 61... As the first slide table 6 slides back and forth, it can effectively improve the problem of uneven wire winding caused by the positional difference between the glass fiber filaments at the end of the first slide block 61 and the glass fiber filaments on the bolt sleeve 3. After the wire winding is completed, the first slide block 61 retracts to one side of the first slide table 6, making it convenient to remove the wire-wound bolt sleeve 3.

The output end of the seventh driving part 54 is fixedly connected to the second base 53 and drives the second base 53 to slide on the first slide rail 531, so that the knotting support rod 511 extends to the surface of the bolt sleeve for knotting, or the knotting support rod 511 retracts back to its original position. Preferably, the seventh driving part 54 is a cylinder.

[0038] In a preferred embodiment, a support plate 532 is fixedly connected to the second base 53.

A rotating bushing 51 is rotatably disposed on the outside of the sleeve 533 via a bearing, and a knotting support rod 511 is disposed on the rotating bushing 51. A sixth drive unit 534 is also provided on the support plate 532. The sixth drive unit 534 drives the rotating bushing 51 to rotate via a second belt 535, so that the knotting support rod 511 rotates around the axis of the bolt sleeve 3 to form a knotting ring. Preferably, the sixth drive unit 534 is a servo motor.

[0039] A second support base 521 is also provided on the frame 1 of the wire winding machine. A slide plate 524 inclined towards the bolt sleeve 3 is provided on the second support base 521.

The knotting clamp 52 is connected to the output end of the secondary drive cylinder 523. By setting the knotting clamp 52 to a two-stage telescopic design, the telescopic accuracy of the knotting clamp 52 can be controlled more precisely.

[0040] A tensioning assembly 62 for tightening the knot formed by the knotting assembly 5 is provided on the first slide table 6. The tensioning assembly 62 includes a first guide roller 621 and a second guide roller 622. A pressure roller 623 is provided in the gap between the first guide roller 621 and the second guide roller 622. The pressure roller 623 is connected to the output end of the eleventh drive unit 624. The eleventh drive unit 624 can drive the pressure roller 623 to move up and down. The glass fiber passes over the first guide roller 621 and the second guide roller 622, and the pressure roller 623 is positioned above the glass fiber. A stop assembly 63 is provided on the rear side of the tensioning assembly 62 to clamp the glass fiber filaments and stop feeding. The stop assembly 63 includes a fixed pressure plate 631 and a movable pressure plate 632 arranged opposite to each other. The fixed pressure plate 631 is fixed on the first slide table 6, and the movable pressure plate 632 is fixedly connected to the output end of the twelfth drive unit 633.

The glass fiber filaments pass between the fixed pressure plate 631 and the movable pressure plate 632, and the movable pressure plate 632 moves relative to the fixed pressure plate 631.

[0041] After passing upward between the fixed pressure plate 631 and the movable pressure plate 632, the fiberglass filaments reach the tensioning assembly 62, then pass horizontally through the tension controller 66 and extend from the first slide 61 to the top of the bolt sleeve for feeding.

[0042] A tension controller 66 is provided between the first slide block 61 and the tensioning assembly 62. The tension controller 66 includes a support roller 661 and a damping roller 662, which are arranged vertically on the first slide block 6. The damping roller 662 is connected to a magnetic damper 663. The damping roller 662 is fixedly connected to the output end of the tension driver 664. The tension driver 664 drives the damping roller 662 to move vertically, and the glass fiber filaments pass between the support roller 661 and the damping roller 662. When winding, the damping roller 662 presses on the support roller 661 to make the glass fiber filaments more tightly wound on the bolt sleeve. When the winding is completed and knotting is performed, the tension driver 664 drives the damping roller 662 to rise and relieve the pressure on the glass fiber filaments, which facilitates the glass fiber filaments to extend or be pressed down by the pressure rollers for knotting. The tension driver 664 is preferably a cylinder.

[0043] In one embodiment, multiple auxiliary guide rollers 67 and multiple sets of wire separators 68 are provided on the first slide table 6 and the first slide block 61.

After knotting, the wire cutter 64 clamps the fiberglass filament between the bolt sleeve and the first slide block to prevent it from falling off the first slide block 61 after being cut. At the same time, the pneumatic scissors 65 cuts the fiberglass filament on the lower side of the wire cutter 64 to facilitate the movement of the first slide block 61 towards the first slide table 6. Furthermore, the first slide table 6 is provided with an eighth drive unit 611, a ninth drive unit 641, and a tenth drive unit 651. The eighth drive unit 611 is used to drive the first slide block 61 to extend or retract horizontally, the ninth drive unit 641 is used to drive the wire cutter 64 to extend or retract horizontally, and the tenth drive unit 651 is used to drive the pneumatic scissors 65 to extend or retract horizontally.

[0048] A first mounting base 26 is fixedly connected to the base plate 28, and a second drive unit 74 is fixedly connected to the first mounting base 26. The second drive unit 74 includes a first cylinder 741 and a push plate 742. The push plate 742 has a through hole in the middle, and a telescopic rod 72 is rotatably connected to the through hole through a second bearing 743. The two sides of the push plate 742 are fixedly connected to the telescopic rod of the first cylinder 741, respectively. The first cylinder 741 drives the telescopic rod 72 to extend and retract within the rotating shaft 21. When winding is not required, the first cylinder 741 drives the telescopic rod 72 and the wire clamp 71 to move along the axis of the bolt sleeve 3 and retract to the surface of the rotating shaft 21 through the push plate 742, so as to avoid the wire clamp 71 affecting the winding of the bolt sleeve. When winding begins, the first cylinder 741 pushes the telescopic rod 72 and the wire clamp 71 along the axis of the bolt sleeve 3 to the upper side of the surface of the bolt sleeve 3 through the push plate 742, so as to easily clamp the end of the glass fiber.

[0049] In a preferred embodiment, a first support base 241 is provided on the frame 1. The first support base 241 is provided with a third slide rail 244 and a fifteenth drive unit 243. The output end of the fifteenth drive unit 243 is fixedly connected to a telescopic shaft 24 and drives the telescopic shaft 24 to slide relative to the rotating shaft on the third slide rail 244, thereby fixing the bolt sleeve between the rotating shaft 21 and the telescopic shaft 24. Further, a first positioning sleeve 213 is fixedly connected to the end of the rotating shaft 21, and a second positioning sleeve 242 is rotatably connected to the end of the telescopic shaft 24. The bolt sleeve 3 is fixed between the first positioning sleeve 213 and the second positioning sleeve 242, and the rotating shaft 21 drives the bolt sleeve 3 and the second positioning sleeve 242 to rotate and wind wire. Furthermore, a conical platform 214 that matches the inner diameter of the bolt sleeve 3 is provided on the surface of the first positioning sleeve 213 and the second positioning sleeve 242, which facilitates fixing the bolt sleeve and prevents it from shifting or falling off during rotation.

[0050] In one embodiment, an adjustment assembly 8 is provided on the frame 1. The adjustment assembly 8 includes a lead screw 81, which is rotatably mounted on the frame and connected to a fourteenth drive unit 82 at one end. Reverse threads are provided on both sides of the lead screw 81. A base plate 28 and a first support seat 241 are slidably mounted on the lead screw 81. The fourteenth drive unit 82 drives the lead screw 81 to rotate, thereby moving the base plate 28 and the first support seat 241 closer or further apart, thus adjusting the spacing of the rotating wire winding assembly 2, making it suitable for bolt sleeves of different lengths. Furthermore, a slide rail is also provided on the frame, and a slider is provided on the base plate 28 and the first support seat 241, sliding on the slide rail.

[0051] In a preferred embodiment, a positioning component is also included for positioning the wire clamp 72. The positioning component includes a proximity switch 27 and a baffle 271. The proximity switch 27 is disposed on the base plate 28, and the baffle 271 is disposed on the rotating shaft 21. Before the winding begins, the baffle 271 rotates with the rotating shaft 21 to the front of the proximity switch 27, and the rotating shaft 21 stops rotating. At this time, the positioning clamp 62 is located directly below the wire break clamp 64 of the wire feeding component.

[0052] In a preferred embodiment, a pneumatic slip ring 711 is fixedly connected to the end of the telescopic rod 72 away from the line clamp 71. The fixed end of the pneumatic slip ring 711 is connected to an air source that drives the line clamp 71, and the rotating end of the pneumatic slip ring 711 is connected to an air cable. The air cable passes through the telescopic rod 72 and connects to the line clamp 71, so that when the line clamp 71 rotates, it does not affect the power provided for opening and closing the line clamp 71. Furthermore, an L-shaped second reinforcing plate 722 is fixedly connected to the push plate 742. One end of the second reinforcing plate 722 is fixedly connected to the push plate 742, and the other end is fixed to the fixed end of the pneumatic slip ring 711.

[0053] In a preferred embodiment, a mounting block 731 is provided on the base plate 28. The mounting block 731 contains an air passage. One end of the air passage is connected to compressed air, and the other end is connected to a universal bamboo tube 732. A nozzle 73 is located at the end of the universal bamboo tube 732, and the opening of the nozzle 73 is flat. Compressed air is blown through the universal bamboo tube 732 and the nozzle 73 towards the fiberglass ends on the surface of the bolt sleeve. The universal bamboo tube 732 facilitates adjustment of the nozzle's position and direction.

[0054] The feeding assembly 4 includes a first base 41, which is fixedly connected to the frame 1. A first slide rail 42 and a third drive unit 44 are fixedly connected to the first base 41. The first slide rail 42 is located on the lower side of the rotating winding assembly 2 and is perpendicular to the axis of the rotating winding assembly 2, that is, perpendicular to the axis of the bolt sleeve 3. The first slide rail 42 extends to the outside of the winding machine frame 1. A second slide block 43 is provided on the first slide rail 42. The third drive unit 44 drives the second slide block 43 to slide on the first slide rail 42. The second slide 43 is provided with a fourth drive unit 462, the output end of which is fixedly connected to the lower side of the lifting seat 46 to drive the lifting seat 46 to move up and down; the lifting seat 46 is also provided with a fifth drive unit 472, the output end of which is fixedly connected to the second slide 47 and drives the second slide 47 to move along the axis of the bolt sleeve 3; at least two sets of positioning blocks 48 are provided at intervals in the middle of the third slide 47, and the positioning blocks 48 are provided with V-grooves 481 or U-grooves that match the size of the bolt sleeve.

[0055] When it is necessary to place the bolt sleeve, the second slide 43 extends along the first slide rail 42 to the outside of the frame 1 and places the bolt sleeve in the V-groove 481. The second slide 43 retracts along the first slide rail 42 to directly below the axis of the rotating winding assembly 2. Then, the lifting seat 6 moves upward to make the bolt sleeve 3 coaxial with the rotating winding assembly 2. Finally, the third slide 47 slides along the axis of the bolt sleeve 3 and rotates the shaft 21 to make the end face of the bolt sleeve contact the end of the rotating shaft 21. At this time, the telescopic shaft 24 moves toward the bolt sleeve, thereby stably clamping and fixing the bolt sleeve on the rotating winding assembly 2, thus avoiding the problem of the rotating winding assembly 2 pushing the bolt sleeve to move horizontally and causing it to be eccentric. After the wire winding is completed, the feeding assembly moves to the lower side of the rotating wire winding assembly 2 and puts the bolt sleeve 3 into the V-groove 481. Then the rotating wire winding assembly 2 loosens the bolt sleeve 3. The third slide 47 drives the bolt sleeve 3 to move in the opposite direction to avoid the conical platform on the end face of the first positioning sleeve 213. After the lifting seat 46 descends, the second slide 43 drives the bolt sleeve 3, which has completed the wire winding, to slide to the outside of the frame 1, so as to facilitate the replacement of a new bolt sleeve.

[0056] In a preferred embodiment, the first slide rail 42 has two tracks, and the second slide block 43 includes two vertical plates 431 and a horizontal plate 432. The vertical plates 431 are connected to both sides of the horizontal plate 432 to form a portal structure. An ear plate 435 is fixedly connected to the bottom side of the vertical plates 431, and a second slider 45 that cooperates with the first slide rail 42 is connected to the ear plate 435. A second reinforcing plate 433 is also fixedly connected between the two vertical plates 431, and the middle part of the second reinforcing plate 433 is fixedly connected to the output end of the third drive unit 44.

[0057] In a preferred embodiment, a plurality of vertical guide rods 463 are provided on the lower side of the lifting seat 46. The guide rods 463 are arranged around the lifting seat 46. A guide sleeve 434 that cooperates with the guide rods 463 is provided on the horizontal plate 432. When the lifting seat 6 moves up and down, the guide rods 463 slide up and down in the guide sleeve 434, thereby improving the stability of the lifting movement of the lifting seat 6.

[0058] Two second slide rails 461 are fixedly connected to the upper surface of the lifting seat 46. The second slide rails 461 are parallel to the axis of the rotating winding assembly 2. A third slider 471 that cooperates with the second slide rails 461 is fixedly connected to the bottom side of the third slide seat 47.

[0059] A bracket 491 is also provided around the second slide block 43. A through-beam sensor 49 is installed on the bracket 491. The through-beam sensor 49 is used to detect the bolt sleeve placed on the positioning block 48. Preferably, two sets of through-beam sensors 49 are provided, and they are respectively located on both sides of the positioning block 48. When the signal of the through-beam sensor 49 is blocked, it means that the bolt sleeve 3 is placed on the positioning block 48. At this time, the feeding assembly moves closer to the rotating winding assembly 2 to feed the material or moves away from the rotating winding assembly 2 to unload the material. When the through-beam sensor 49 can detect the signal, it means that the bolt sleeve 3 is not placed on the positioning block 48 or the bolt sleeve is not placed in place. At this time, the feeding assembly will not move.

[0060] In use, the end of the fiberglass filament is passed upward through the stop assembly 63 to the tension assembly 62, and then guided from the tension controller 66 through the first slide 61. The first slide 61 extends directly above the bolt sleeve 3 and the wire break clamp 64 clamps the fiberglass filament.

[0061] After the third drive unit 44 drives the second slide 43 to extend to the outside of the winding machine frame 1, the worker places the bolt sleeve 3 in the V-groove 481. The through-beam sensor 49 detects the signal interruption, and the control unit controls the third drive unit 44 to retract the second slide 43 to directly below the axis of the rotating winding assembly 2. Then, the fourth drive unit 462 drives the lifting seat 6 to move upward so that the bolt sleeve 3 is coaxial with the rotating winding assembly 2. Finally, the fifth drive unit 472 drives the second slide 47 to slide along the axis of the bolt sleeve 3 to the end of the first positioning sleeve 21 and to put the bolt sleeve 3 on the conical platform 23 until it contacts the end face of the first positioning sleeve 21. Then, the second positioning sleeve 22 moves toward the bolt sleeve 3 and clamps and fixes the bolt sleeve 3 between the first positioning sleeve 21 and the second positioning sleeve 22, thereby stably clamping and fixing the bolt sleeve on the rotating winding assembly 2.

[0062] Rotating shaft 21 rotates to make baffle 271 rotate to the front of proximity switch 27. At this time, the fixed wire clamp 71 is directly below the broken wire clamp 64. The fixed wire clamp 71 opens to clamp the end of the glass fiber, and the broken wire clamp 64 opens to release the end of the glass fiber.

[0063] The first drive unit 23 drives the rotating shaft 21 to rotate, the first slide table 6 drives the first slide block 61 to move along the length direction of the bolt sleeve, the glass fiber clamped by the bolt sleeve 3 and the wire clamp 71 rotates accordingly, so that the glass fiber is wound on the surface of the bolt sleeve 3, the wire feeding assembly drives the glass fiber to reciprocate, so that the glass fiber wound later presses down on the glass fiber wound earlier. Then the wire clamp 71 releases the glass fiber and resets, and the bolt sleeve 3 rotates quickly to start winding the wire.

[0064] After the winding is completed, the seventh drive unit 54 drives the knotting support rod 511 to extend to the glass fiber of the bolt sleeve 3. The rotating bushing 51 drives the knotting support rod 511 to rotate, so that the glass fiber wraps around the first support rod 512 and the second support rod 513 to form a knot loop. Then the wire feeding assembly moves slightly away from the knotting support rod 511 so that the glass fiber misses the first support rod 91 and passes obliquely through the knot loop. The wire feeding assembly returns to the side close to the knotting support rod 511. The knotting clamp 52 extends between the first support rod 512 and the second support rod 513 and passes through the knot loop to clamp the glass fiber.

[0065] The wire feeding assembly moves away from the knotting support rod 511 again, causing the fiberglass filament between the bolt sleeve 3 and the first slide block 61 to extend, making it easier for the knotting clamp 52 to pull the fiberglass filament. Then the wire feeding assembly moves closer to the knotting support rod 511 again, and the secondary drive cylinder 523 drives the knotting clamp 52 to retract and pull the fiberglass filament through the knotting ring.

[0066] The seventh drive unit 54 drives the knotting support rod 511 to retract and return to its original position, disengaging from the knotting ring. The fixed pressure plate 631 moves towards the movable pressure plate 632 to press the glass fiber filaments. At the same time, the bolt sleeve 3 rotates to tighten the knotting ring and wrap it around the bolt sleeve 3 to form a knot.

[0067] Then, the knotting clamp 52 releases the fiberglass filament, and the first-stage telescopic cylinder 522 drives it to retract and return to its original position; the damping roller 662 rises, and the pressure roller 623 moves downward to pull back the fiberglass filament, causing the fiberglass filament pulled up by the knotting clamp 52 to retract and tighten the knot to complete the knotting process.

[0068] The ninth drive unit 641 drives the wire break clamp 64 to extend and clamp the glass fiber filament, the tenth drive unit 651 drives the scissors to extend and cut the glass fiber filament, the first slide block 61 retracts to one side of the first slide table 6, and at the same time the pressure roller 623 presses down again to straighten the glass fiber filament.

[0069] The feeding assembly 4 removes the finished bolt sleeve 3 and sends it out of the wire winding machine. The worker places the new bolt sleeve on the feeding assembly 4 and begins to wind the next bolt sleeve.

[0070] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
