AI Technical Summary
In existing wire winding machines, when the wire feeding assembly slides to one end of the bolt sleeve, the glass fiber cannot move horizontally to the end of the bolt sleeve, resulting in the glass fiber wrapped at both ends of the bolt sleeve being too thin or not wrapped at all, affecting the winding quality.
The fiber feeding and knotting device includes a first slide, a knotting assembly, and a tensioning assembly. The first slide slides the fiber along the length of the bolt sleeve, and the knotting support rod and knotting clamp form a knotting ring. Combined with the rotating bushing and guide roller structure, the uniform winding and automatic knotting of the glass fiber is achieved.
The method achieves uniform winding of fiberglass filaments on the surface of the bolt sleeve, ensuring uniform winding thickness at both ends of the bolt sleeve, and improves the winding quality by automatically knotting and fixing the tail of the fiberglass filaments.

Technical Field
[0001] This utility model relates to the field of wind turbine blade production and processing technology, specifically to a wire feeding and knotting device for a wind turbine blade bolt winding machine. 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 usually pre-embedded at the end face of the blade root, connecting the wind turbine blade and the hub together. To enhance the strength of the bolt sleeves embedded in the blade, fiberglass filaments are wound around the surface of the bolt sleeves. Existing technology uses a wire winding machine to automatically wind the bolt sleeves. The wire winding machine includes a wire winding assembly, and a wire feeding assembly is located on one side of the wire winding assembly. The wire feeding assembly slides along the length of the bolt sleeve to deliver the fiberglass filaments to the surface of the bolt sleeve for uniform winding. However, during use, it has been found that when the wire feeding assembly slides to one end of the bolt sleeve, the fiberglass filaments are only actually wound to the middle of the bolt sleeve. At this point, the wire feeding assembly begins to slide to the other end of the bolt sleeve, and the fiberglass filaments slide to the right. This prevents the fiberglass filaments from moving horizontally to the ends of the bolt sleeve, resulting in thinner or no fiberglass filaments at either end of the bolt sleeve. This affects the winding quality of the fiberglass filaments. In addition, the position of the fiberglass filaments on the surface of the bolt sleeve is related to the sliding speed of the wire feeding assembly and the rotation speed of the bolt sleeve. Therefore, simply lengthening the slide of the wire feeding assembly is not very effective. Utility Model Content

The glass fiber filaments pass through the first slide block and are wound onto the bolt sleeve. The knotting assembly includes a rotating bushing and a knotting clamp. The rotating bushing is coaxially arranged with the bolt sleeve and can rotate around the axis of the bolt sleeve. A knotting support rod is provided on one side of the rotating bushing, and the knotting support rod includes a first support rod and a second support rod. A knotting clamp extends between the first and second support rods to clamp and pull the fiberglass filament through the space between them. A tensioning assembly is also provided on the first slide, comprising a first guide roller and a second guide roller. A pressure roller that can move up and down is provided in the gap between the first and second guide rollers. The fiberglass filament passes over the first and second guide rollers, and the pressure roller is positioned above the fiberglass filament. A stop assembly is provided on the rear side of the tensioning assembly, comprising a fixed pressure plate and a movable pressure plate arranged opposite each other. The fiberglass filament passes between the fixed pressure plate and the movable pressure plate, and the movable pressure plate moves relative to the fixed pressure plate.
[0006] Preferably, a wire cutter and a pneumatic scissor are movably mounted on the first slide. The wire cutter and the pneumatic scissor are sequentially arranged on the lower side of the first slide, and the wire cutter and the pneumatic scissor have the same extension and retraction direction as the first slide.
[0007] Preferably, the knotting assembly further includes a base and a first slide rail, the first slide rail being arranged along the length direction of the bolt sleeve, and the rotating bushing being rotatably mounted on the base; a second drive unit is fixedly connected to the frame of the winding machine, and the output end of the second drive unit is fixedly connected to the base and drives the base to slide on the first slide rail.
[0008] Preferably, a support plate is fixedly connected to the base, a sleeve is provided on the support plate, the rotating bushing is rotatably mounted on the sleeve through a bearing, and a first driving part is also provided on the support plate, the first driving part drives the rotating bushing to rotate through a belt.
[0009] Preferably, a positioning and rotating assembly is provided on the frame of the wire winding machine for fixing and driving the bolt sleeve to rotate, and one side of the positioning and rotating assembly passes through the sleeve of the support plate.
[0010] Preferably, the frame of the winding machine is further provided with a support base, and a slide plate inclined towards the bolt sleeve is provided on the support base. A primary drive cylinder is provided on the slide plate, and a secondary drive cylinder is connected to the output end of the primary drive cylinder. The knotting clamp is connected to the output end of the secondary drive cylinder.
[0011] Preferably, the frame of the winding machine is provided with a first lead screw and a second slide rail. The bottom of the first slide table is fixedly connected with a first sliding sleeve and a first slider. The first sliding sleeve is slidably disposed on the first lead screw and the first slider is disposed on the second slide rail.
[0012] Preferably, a tension controller is provided on the rear side of the first slide block. The tension controller includes a support roller and a damping roller arranged vertically on the first slide block. Fiberglass filaments pass between the support roller and the damping roller. The damping roller is connected to a magnetic damper and can move up and down in the vertical direction.
[0013] Preferably, multiple auxiliary guide rollers are provided between the tensioning assembly and the first slide block, and multiple sets of wire separators are provided on the first slide block; a wire threading ring is provided on the first slide block.
[0014] Preferably, the extension length of the knotting support rod is consistent with the length direction of the bolt sleeve, and the support plate is disposed at the movable end of the positioning and rotating assembly of the winding machine and is coaxially disposed with the positioning and rotating assembly.
[0015] The beneficial effects of this utility model are:
[0016] In the above technical solution, the wire feeding assembly includes a first slide table. The first slide table slides along the length of the bolt sleeve 3 to facilitate the uniform winding of glass fiber filaments onto the surface of the bolt sleeve. A first slide block is provided on the first slide table. After passing through the first slide block, the glass fiber filaments are wound onto the bolt sleeve. When the bolt sleeve rotates and winds the wire, the first slide block extends to directly above the bolt sleeve to feed the wire. 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 to feed the wire, the glass fiber filaments between the end of the first slide block and the bolt sleeve are always in a basically vertical state, thereby minimizing the horizontal positional difference between the glass fiber filaments at the end of the first slide block and the end of the bolt sleeve. When the first slide block moves to the end of the bolt sleeve, the glass fiber filaments follow and wind onto the end of the bolt sleeve, thereby effectively improving the problem of uneven winding at the end of the bolt sleeve surface.
[0017] After the fiber winding is completed, the rotating bushing drives the knotting support rod to extend to the position of the fiberglass filament on the bolt sleeve. The rotating bushing also drives the knotting support rod to rotate, causing the fiberglass filament to wrap around the first and second support rods to form a knot loop. The rotation direction of the knotting support rod is the same as the rotation direction of the fiber winding on the bolt sleeve. Then, the fiber feeding assembly moves away from the knotting support rod, causing the fiberglass filament to miss the first support rod and pass diagonally through the knot loop. The knotting clamp extends between the first and second support rods and passes through the knot loop to clamp the fiberglass filament. The knotting clamp retracts, pulling the fiberglass filament through the knot loop. Then, the knotting support rod retracts back to its original position and disengages from the knot loop. The stop assembly presses the fiberglass filament tightly, stopping the fiber feeding. Simultaneously, the bolt sleeve rotates, tightening the knot loop and wrapping it around the bolt sleeve to form a knot. Then, the knotting clamp releases the fiberglass filament, and the pressure roller moves downwards to press the fiberglass filament tightly, causing the fiberglass filament pulled up by the knotting clamp to retract, tightening the knot and completing the knotting process.

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0027] like Figures 1 to 7 As shown, a wire feeding and knotting device for a wind turbine blade bolt sleeve winding machine includes a wire feeding assembly and a knotting assembly 5 mounted on the frame 1 of the winding machine. The wire feeding assembly includes a first slide table 6, which slides along the length of the bolt sleeve 3. A first slide block 61 is provided on the first slide table 6 near the bolt sleeve 3, and the first slide block 61 can extend to directly above the bolt sleeve 3 for wire feeding. After passing through the first slide block 61, the fiberglass filaments are wound onto the bolt sleeve 3. When the bolt sleeve 3 rotates and winds, the first slide block 61 extends to directly above the bolt sleeve 3, and the fiberglass filaments are 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, when the first slide block 61 reciprocates with the first slide table 6, the problem of uneven winding caused by the positional difference between the fiberglass filaments at the end of the first slide block 61 and the fiberglass filaments on the bolt sleeve 3 can be effectively improved. Once the wire winding is complete, the first slide block 61 retracts to one side of the first slide table 6, making it convenient to remove the finished bolt sleeve 3.
[0028] The knotting assembly 5 includes a rotating bushing 51 and a knotting clamp 52. The rotating bushing 51 is coaxially arranged with the bolt sleeve 3 and can rotate around the axis of the bolt sleeve 3. A knotting support rod 511 is provided on the rotating bushing 51. The extension direction of the knotting support rod 511 is consistent with the length direction of the bolt sleeve 3. The knotting support rod 511 includes a first support rod 512 and a second support rod 513. The knotting clamp 52 extends between the first support rod 512 and the second support rod 513 to clamp and pull the glass fiber filament through the first support rod 512 and the second support rod 513. The knotting assembly 5 also includes a base 53 and a first slide rail 531. The rotating bushing 51 is disposed on the base 53. The first slide rail 531 is disposed on the support base 241 along the length of the bolt sleeve 3. A second drive unit 54 is provided on the frame 1. The output end of the second drive unit 54 is fixedly connected to the base 53 and drives the base 53 to slide on the first slide rail 531. Preferably, the second drive unit 54 is a cylinder.
[0029] In one embodiment, a support plate 532 is fixedly connected to the base 53. The support plate 532 is disposed at one end of the positioning and rotating assembly 2 of the wire winding machine and is coaxially arranged with the positioning and rotating assembly 2. Preferably, the support plate 532 is disposed at the movable end of the support plate 532. A sleeve 533 is provided on the support plate 532, and the movable end of the positioning and rotating assembly 2 passes through the sleeve 533. A rotating bushing 51 is rotatably disposed on the sleeve 533 via a bearing. 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. Preferably, the first drive unit 534 is a servo motor.
[0030] In one embodiment, a support base 521 is also provided on the frame 1 of the winding machine. A slide plate 524 inclined towards the bolt sleeve 3 is provided on the support base 521. A primary drive cylinder 522 is provided on the slide plate 524. The output end of the primary drive cylinder 522 is connected to a secondary drive cylinder 523. 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.
[0031] A tensioning assembly 62 is also 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 sixth drive unit 624, which can drive the pressure roller 623 to move up and down. Fiberglass filaments pass over the first guide roller 621 and the second guide roller 622, and the pressure roller 623 is positioned above the fiberglass filaments. 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 seventh drive unit 633. The seventh drive unit 633 is fixedly connected to the first slide table 6. The seventh drive unit 633 drives the movable pressure plate 632 to move closer to or away from the fixed pressure plate 631. 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.
[0032] After the fiber winding is completed, the second drive unit 54 drives the knotting support rod 511 to extend to the middle of the bolt sleeve 3. The rotating bushing 51 drives the knotting support rod 511 to rotate in the same direction as the bolt sleeve 3, so that the fiberglass filaments are wrapped around the first support rod 512 and the second support rod 513 to form a knot loop. Then, the wire feeding assembly 6 moves away from the knotting support rod 511, so that the fiberglass filaments miss the second support rod 513 and pass obliquely through the knot loop. The wire feeding assembly 6 then moves closer to the knotting support rod 511, and 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 fiberglass filaments. The knotting clamp 52 retracts and pulls the fiberglass filaments through the knot loop. Then, the second drive unit 54 drives the knotting support rod 511 to retract and return to its original position to disengage from the knot loop. The movable pressure plate 632 moves towards the fixed pressure plate 631 to press the fiberglass filaments tightly. At the same time, the bolt sleeve 3 rotates to tighten the knot loop and wrap it around the bolt sleeve 3 to form a knot. Then, the knotting clamp 52 releases the fiberglass filaments, and the pressure roller 623 moves downward to press the fiberglass filaments, causing the fiberglass filaments pulled up by the knotting clamp 52 to retract and tighten the knot. After that, the fiberglass filaments are cut, 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 fiberglass filaments, preventing the fiberglass filaments from tangling together due to the retraction of the first slide block 61.
[0033] A wire-cutting clamp 64 and a pneumatic scissors 65 are movably mounted on the first slide table 6. The wire-cutting clamp 64 and the pneumatic scissors 65 are sequentially arranged on the lower side of the first slide block 61, and their extension and retraction directions are the same as those of the first slide block 61. After knotting, the wire-cutting clamp 64 clamps the fiberglass filament to prevent it from being cut and falling off the first slide block 61, while the pneumatic scissors 65 cuts the fiberglass filament, facilitating the movement of the first slide block 61 towards the first slide table. Further, a third drive unit 611, a fourth drive unit 641, and a fifth drive unit 651 are provided on the first slide table. The third drive unit 611 drives the first slide block 61 to extend or retract horizontally, the fourth drive unit 641 drives the wire-cutting clamp 64 to extend or retract horizontally, and the fifth drive unit 651 drives the pneumatic scissors 65 to extend or retract horizontally. Preferably, the third drive unit 611, the fourth drive unit 641, and the fifth drive unit 651 are all cylinders.
[0034] 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. Fiberglass filaments pass between the support roller 661 and the damping roller 662. The damping roller 662 is connected to a magnetic damper 663 and can move up and down in the vertical direction. When winding the fiberglass, the damping roller 662 presses against the support roller 661 to make the fiberglass filaments more tightly wound on the bolt sleeve. When the winding is completed and knotting is performed, the damping roller 662 rises to release the pressure on the fiberglass filaments, which facilitates the fiberglass filaments to extend or be pressed down for knotting. Furthermore, the damping roller 662 is fixedly connected to the output end of the pressing cylinder 664.
[0035] After passing upward through the stop assembly, the fiberglass filaments reach the tensioning assembly 62, then pass horizontally through the tension controller 66 and extend from the first slide 61 above the bolt sleeve for feeding. The first slide 6 is equipped with multiple auxiliary guide rollers 67 and multiple sets of spacer rods 68, with each set of spacer rods having multiple sections along the length of the auxiliary guide rollers 67. This allows for simultaneous feeding and winding of multiple fiberglass filaments, further increasing the winding speed. Furthermore, the first slide 61 is equipped with a threading ring 613 through which multiple sets of fiberglass filaments pass.
[0036] In use, the end of the fiberglass filament passes upward through the stop assembly 63 to the tension assembly 62, and then is guided from the tension controller 66 to pass through the first slide block 61. The first slide block 6 drives the first slide block 61 to move along the length direction of the bolt sleeve, and 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 around the bolt sleeve 3. After the bolt sleeve 3 is fixed to the positioning and rotating assembly 2, the positioning and rotating assembly 2 drives the bolt sleeve 3 to rotate and wind the filament. After the winding is completed, the second 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 in the same direction as the bolt sleeve 3, 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 6 moves away from the knotting support rod 511 so that the glass fiber misses the second support rod 513 and passes obliquely through the knot loop. The wire feeding assembly 6 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. At this point, the fiber feeding assembly 6 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 fiber feeding assembly 6 moves closer to the knotting support rod 511 again, and the secondary drive cylinder 523 drives the knotting clamp 52 to retract, pulling the fiberglass filament over the knotting ring. Afterwards, the second drive unit 54 drives the knotting support rod 511 to retract and disengage from the knotting ring. The fixed pressure plate 631 moves towards the movable pressure plate 632 to press the fiberglass filament tightly. Simultaneously, the bolt sleeve 3 rotates, tightening the knotting ring and wrapping it around the bolt sleeve 3 to form a knot. Then, the knotting clamp 52 releases the fiberglass filament, and the primary telescopic cylinder 522 drives the knotting clamp to retract. The damping roller 662 rises, and the pressure roller 623 moves downward to press the fiberglass filament, causing the fiberglass filament pulled up by the knotting clamp 52 to retract, tightening the knot and completing the knotting process. Then, the fourth drive unit 641 drives the wire-breaking clamp 64 to extend and clamp the glass fiber filament, the fifth 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, so as to prevent the glass fiber filaments from getting tangled together due to the retraction of the first slide block 61.
[0037] 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.
