Description

Technical Field

[0001] This application relates to the field of textile equipment technology, and in particular to an automatic reel-changing take-up machine and a knotting method. Background Technology

[0002] In the textile production field, take-up machines are used to orderly wind continuous yarn from the output end of the large spool or processing equipment in the production process onto relatively small take-up reels such as I-beams, so as to facilitate subsequent yarn storage, transportation, inspection and further processing, and ensure that the entire production line can achieve continuous and efficient operation.

[0003] In the actual operation of the take-up machine, after the wire on a spool is fully wound according to production requirements, in order to prevent the wire from loosening and falling off on the full spool, the end wire needs to be knotted before the spool is replaced. However, existing take-up machines usually rely on manual labor to perform the above knotting operation, which reduces the efficiency of manual operation and has obvious shortcomings. Summary of the Invention

[0004] In order to achieve automatic knotting of the yarn inside the take-up machine and improve the working efficiency of the take-up machine, this application provides an automatic reel-changing take-up machine.

[0005] The automatic reel-changing take-up machine and knotting method provided in this application adopt the following technical solution: An automatic reel-changing take-up machine includes: a chassis, a first base disposed inside the chassis, a main shaft rotatably connected inside the first base, an end of the main shaft extending out of the first base and mounted on an I-beam wheel, a wire wound on the I-beam wheel, and a first drive mechanism for driving the main shaft to rotate. A cable routing mechanism is disposed inside the chassis, and the cable routing mechanism is used to pull the wire to move along the axis of the main shaft. A knotting mechanism includes a mounting plate disposed at the end of the main shaft. A sliding seat is provided on the surface of the mounting plate. A first clamping block and a second clamping block are disposed at the end of the sliding seat near the I-beam wheel. The second clamping block is hinged to the sliding seat. A control component is provided on the mounting plate to drive the second clamping block to disengage from or abut against the first clamping block. A first drive cylinder is disposed on the first base. A pneumatic shear is disposed at the moving end of the first drive cylinder. An clearance groove is provided on the mounting plate for the pneumatic shear to slide. The second drive mechanism is used to drive the mounting plate to rotate in the forward or reverse direction.

[0006] By adopting the above technical solution, after the yarn is fully laid out, the second drive mechanism drives the mounting plate to rotate forward, and the yarn is wound around the outer ring of the first and second clamping blocks to form a basic coil. Then, the yarn laying mechanism drives the yarn to move into the inside of the first and second clamping blocks. The second drive mechanism drives the mounting plate to rotate in the opposite direction, so that the yarn is wound around the second clamping block in the opposite direction. When the clearance groove moves to face the pneumatic scissors, the second drive mechanism stops the rotation of the mounting plate, and the control component drives the second clamping block to abut against the first clamping block. At this time, the outer yarn comes out to form a knot. Then, the first drive cylinder pushes the pneumatic scissors to move out of the clearance groove and cut the yarn. Finally, the first drive mechanism drives the main shaft to drive the I-beam wheel to rotate in the opposite direction. The I-beam wheel tightens the yarn at the closing point of the first and second clamping blocks. In this way, the yarn is automatically knotted. Compared with the traditional manual knotting operation, it saves time and effort, thereby improving the working efficiency of the take-up machine.

[0007] Optionally, the control component includes a sliding block slidably connected within the sliding seat. A first connecting rod is hinged to the end of the sliding block near the first clamping block. The first connecting rod is hinged to the second clamping block. A driving block is provided at the end of the sliding block. A mounting shaft is provided on the driving block and slidably passes through the interior of the sliding seat. A return spring is sleeved on the outer surface of the mounting shaft. The elastic force of the return spring drives the first clamping block and the second clamping block to remain in an open / closed state. A second driving cylinder is provided on the first base. When the clearance groove is directly opposite the pneumatic scissors, the second driving cylinder is directly opposite the driving block.

[0008] By adopting the above technical solution, when the mounting plate rotates to the position where the clearance groove is directly opposite the pneumatic scissors, the piston rod of the second drive cylinder extends and pushes the drive block to move. The drive block overcomes the elastic force of the return spring and drives the first connecting rod to rotate around the hinge point. The first connecting rod drives the second clamping block to rotate toward the first clamping block, thereby achieving the clamping of the wire. When the piston rod of the second drive cylinder disengages from the drive block, the elastic force of the return spring pushes the drive block to reset. The drive block drives the first connecting rod to rotate in the opposite direction, thereby separating the second clamping block from the first clamping block and restoring the open and closed state, so as to perform the next wire winding and clamping operation.

[0009] Optionally, a mounting base is provided inside the chassis along the axial direction of the main shaft. The cable laying mechanism includes a cable laying seat slidably connected to the mounting base. Multiple guide wheels are rotatably connected to the cable laying seat. The wire is wound around the guide wheels. A lead screw and a guide rod are provided inside the mounting base. One end of the cable laying seat is threaded to the lead screw, and the other end is slidably passed through the guide rod. A cable laying motor for driving the lead screw to rotate is provided on the outer surface of the mounting base.

[0010] By adopting the above technical solution, when the lead screw is driven to rotate by the wire feeding motor, the lead screw drives the wire feeding seat to slide along the guide rod. The two guide wheels guide the wire as it moves with the wire feeding seat, so that the wire can move evenly along the axial direction of the main shaft and wind around the I-beam reel. This makes the wire winding on the I-beam reel more neat and even, avoiding wire stacking or loosening, improving the wire capacity and winding quality of the I-beam reel. At the same time, the wire feeding motor drives the automated wire feeding, further reducing the need for manual intervention and improving the overall working efficiency of the winding machine.

[0011] Optionally, the first drive mechanism includes a first motor disposed within the chassis. The output shaft of the first motor is connected to the end of the main shaft away from the mounting plate via a first pulley and a first belt. The second drive mechanism includes a second motor disposed on the first base. The output shaft of the second motor is provided with a reduction gearbox. The two output ends of the reduction gearbox are connected to the two ends of the main shaft via a second pulley and a second belt. The second pulley is rotatably sleeved on the outer surface of the main shaft and is coaxially fixedly connected to the mounting plate via a connecting flange.

[0012] By adopting the above technical solution, the first motor drives the main shaft to rotate through the first pulley and the first belt, thereby realizing the winding action of the I-beam reel; after the second motor is reduced in speed by the gearbox, it drives the second pulley connected to the mounting plate to rotate through the transmission action of the second belt, thereby realizing the forward and reverse rotation of the mounting plate. The first drive mechanism and the second drive mechanism can provide suitable speed and torque for the winding of the I-beam reel and the rotation of the mounting plate, respectively, to meet the different working requirements of the two.

[0013] Optionally, the mounting plate is provided with a support, and a push rod is slidably connected inside the support. A clamp is provided at the end of the push rod extending out of the support. A compression spring is sleeved on the outer surface of the push rod. The elastic force of the compression spring pulls the clamp against the end of the support. A third drive cylinder is provided on the first base. When the clearance groove is directly opposite the pneumatic scissors, the third drive cylinder is directly opposite the push rod.

[0014] By adopting the above technical solution, when the mounting plate rotates to align the clearance groove with the pneumatic shears, the piston rod of the third drive cylinder extends, overcoming the spring force of the compression spring to push the push rod to move, creating a gap between the clamp and the support to accommodate the wire. The tensioned wire can then be easily inserted into this gap. Subsequently, the piston rod of the third drive cylinder retracts, the spring force of the compression spring is released, and the push rod is pulled back to its original position. The clamp moves with the push rod and abuts against the support, thus firmly clamping the wire in the gap. This achieves the clamping of the wire, ensuring that the wire will not loosen or slip during subsequent cutting and knotting processes. This improves the stability of the wire fixation during the knotting process.

[0015] Optionally, a second base is provided at the end of the housing away from the first base. A fourth drive cylinder is provided on each of the two opposite sides of the second base. The piston rods of the two fourth drive cylinders are provided with a connecting plate. A support pin coaxial with the main shaft is provided on the connecting plate. A retaining ring is sleeved on the outer surface of the support pin. When the main shaft rotates, the support pin is inserted into the mounting groove of the I-beam wheel, and the retaining ring is attached to the end face of the I-beam wheel.

[0016] By adopting the above technical solution, when the I-beam is installed on the main shaft, the two fourth drive cylinders operate synchronously, pushing the connecting plate to move the support pin towards the main shaft, so that the support pin is accurately inserted into the mounting groove of the I-beam, while the retaining ring fits against the end face of the I-beam. This structure provides symmetrical thrust through the four fourth drive cylinders on both sides, and with the matching design between the support pin and the mounting groove of the I-beam, it can form stable axial support and radial positioning for the I-beam, preventing axial movement or radial displacement of the I-beam during high-speed rotation of the main shaft to take in the wire or reverse rotation to tighten the wire.

[0017] Optionally, the mounting plate is provided with a connecting frame, and the connecting frame is provided with a wire baffle plate. The end of the wire baffle plate abuts against the end face of the I-beam wheel away from the retaining ring. When knotting, the thread abuts against the wire baffle plate.

[0018] By adopting the above technical solution, when the mounting plate rotates and winds the wire, the wire stop plate can prevent the wire from shifting to the outside of the I-beam wheel, ensuring that the wire is always wound within the preset range, and avoiding uneven winding or knotting failure due to wire position deviation.

[0019] Optionally, a knotting method includes an automatic reel-changing take-up machine, and further includes the following steps: S1: Initial winding: When the wire on the I-beam reel is fully laid, the second drive mechanism drives the mounting plate to rotate in the forward direction. When the mounting plate rotates to the position where the wire is located between the sliding seat and the support, the wire laying mechanism drives the wire to abut against the surface of the wire baffle. As the mounting plate continues to rotate, the wire winds around the outer surfaces of the first clamping block and the second clamping block to form a basic coil. S2: Shifting adjustment: When the support rotates again to be close to the wire, the wire laying mechanism drives the wire to break away from the wire baffle, so as to prevent the wire from getting tangled on the support as the mounting plate rotates; S3: Reverse winding: When the mounting disc rotates to the position where the wire is between the first clamping block and the second clamping block, the mounting disc stops rotating, the wire laying mechanism drives the wire to move into the inside of the first clamping block and the second clamping block, and then the second driving mechanism drives the mounting disc to rotate in the reverse direction, so that the wire is wound in the reverse direction on the second clamping block and the support. S4: Clamping into a loop: When the clearance groove moves to face the pneumatic scissors, the second drive mechanism stops the mounting plate, the control component and the third drive cylinder start synchronously, the second clamping block abuts against the first clamping block, the outer wire comes out to form a loop, and the chuck clamps the wire. S5: Cutting the thread: The first drive cylinder drives the pneumatic shears to extend out of the clearance groove, and the pneumatic shears cut the thread between the support and the sliding seat; S6: Tightening and knotting: The first driving mechanism drives the main shaft to rotate in the opposite direction. When the I-beam wheel rotates, it tightens the thread at the closing point of the first clamping block and the second clamping block, thereby achieving thread knotting.

[0020] By adopting the above technical solution, this application drives the mounting plate to rotate through the second drive mechanism, and in conjunction with the wire laying mechanism and the knotting mechanism, realizes the automatic knotting of the wire. Compared with the traditional manual knotting operation, it saves time and effort, thereby improving the working efficiency of the take-up machine.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This application achieves automatic knotting of the thread by setting a knotting mechanism, which saves time and effort compared to the traditional manual knotting operation, thereby improving the working efficiency of the take-up machine; 2. This application incorporates a wire winding mechanism, which ensures that the wire is wound more neatly and evenly on the I-beam reel, preventing wire stacking or loosening. This improves the wire capacity of the I-beam reel and the winding quality. Furthermore, the wire winding is automated through a wire winding motor, further reducing the need for manual intervention and enhancing the overall working efficiency of the winding machine.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0031] This application discloses an automatic reel-changing take-up machine and a knotting method.

[0032] Example 1 Reference Figure 1 An automatic reel take-up machine includes a housing 1. A tension fixing plate 101 is fixedly installed on the top of the housing 1. A tension assembly 102 for maintaining the tension of the wire is installed on the tension fixing plate 101. The specific composition and technical principle of the tension assembly 102 are existing technologies and are not the focus of this application. Therefore, they will not be described in detail in this embodiment. A control box 103 is installed on the top of the housing 1. The control box 103 integrates electrical components such as a control board. A control panel and control buttons are installed on its surface. All electrical equipment inside the housing 1 is electrically connected to the control box 103.

[0033] Reference Figure 1 and Figure 2The machine housing 1 has a partition 2 installed inside, which divides the interior of the machine housing 1 into an equipment area 104 and a knotting work area 105. A first base 3 is fixedly installed on the inner bottom wall of the machine housing 1 in the equipment area 104. A main shaft 31 is rotatably connected inside the first base 3. The axis of the main shaft 31 is parallel to the length direction of the machine housing 1. One end of the main shaft 31 extends into the knotting work area 105 and is equipped with a bobbin 01. A thread (not shown in the figure) is wound on the bobbin 01. A first drive mechanism 4 is provided inside the equipment area 104. The first drive mechanism 4 includes a first motor 41 (not shown in the figure) installed on the bottom wall of the housing 1. The output shaft of the first motor 41 and the end of the main shaft 31 away from the I-beam 01 are both coaxially fixedly connected to the first pulley 42. The outer surfaces of the two first pulleys 42 are jointly fitted with a first belt 43. When winding the thread, the first motor 41 starts and drives the main shaft 31 to rotate through the transmission action of the first pulley 42 and the first belt 43. The main shaft 31 drives the I-beam 01 to rotate, so that the thread is wound on the I-beam 01.

[0034] Reference Figure 1 and Figure 2 To improve the stability of the H-beam reel 01 during winding, a second base 5 is fixedly installed on the inner bottom wall of the knotting work area 105 of the machine housing 1. A fourth drive cylinder 51 is installed on the outer surface of the second base 5 along the width direction of the machine housing 1. A connecting plate 52 is installed on the piston rod ends of the two fourth drive cylinders 51. A support pin 53 is coaxially fixedly connected to the connecting plate 52 through a connecting flange. The support pin 53 is coaxially arranged with the main shaft 31. The end of the support pin 53 near the first base 3 is fixedly fixed. The fixed sleeve is equipped with a retaining ring 54. When the I-beam wheel 01 is installed on the main shaft 31, the two fourth drive cylinders 51 act synchronously, pushing the connecting plate 52 to drive the support pin 53 to move towards the main shaft 31, so that the support pin 53 is inserted into the mounting groove of the I-beam wheel 01. At the same time, the retaining ring 54 fits against the end face of the I-beam wheel 01. The support pin 53, together with the main shaft 31, can form a stable axial support and radial positioning for the I-beam wheel 01, preventing the I-beam wheel 01 from axially moving or radially shifting when it rotates at high speed with the main shaft 31.

[0035] Reference Figure 1 and Figure 3The machine housing 1 is located on the inner side wall of the knotting work area 105 and is mounted on the axis of the main shaft 31. The mounting base 106 is equipped with a wire laying mechanism 6. The wire laying mechanism 6 includes a wire laying seat 61 slidably connected in the mounting base 106. The wire laying seat 61 is rotatably connected to multiple guide wheels 62 facing the inside of the machine housing 1. In this embodiment, there are two guide wheels 62. After the wire passes through the tension component 102, it passes through the two guide wheels 62 in sequence and is wound on the I-beam wheel 01. The mounting base 106 is equipped with a lead screw 63 and a guide rod 64 along the length direction. One end of the wire laying seat 61 is threaded to the lead screw 63, and the other end is slidably passed through the guide rod 64. The outer surface of the mounting base 106 is fixedly mounted with a wire laying motor 65 that drives the lead screw 63 to rotate.

[0036] When the wire is wound up, the wire winding motor 65 drives the lead screw 63 to rotate. The lead screw 63 drives the wire winding seat 61 to slide along the guide rod 64. The two guide wheels 62 guide the wire as it moves with the wire winding seat 61, so that the wire can move evenly along the axial direction of the main shaft 31 and wind around the I-beam wheel 01. This makes the wire more neat and evenly wound on the I-beam wheel 01, avoiding the phenomenon of wire stacking or loosening.

[0037] Reference Figure 4 , Figure 5 and Figure 6 The machine housing 1 is equipped with a knotting mechanism 7 for automatic knotting. The knotting mechanism 7 includes a mounting plate 71 rotatably sleeved on the end of the main shaft 31. The mounting plate 71 is located inside the knotting working area 105. A second drive mechanism 8 is provided on the first base 3. The second drive mechanism 8 includes a second motor 81 fixedly mounted on the first base 3. The output shaft of the second motor 81 is connected to a reduction gearbox 82. The specific composition and working principle of the reduction gearbox 82 are existing technologies and will not be described in detail in this embodiment. The two output ends of the reduction gearbox 82 are connected to a second pulley 83 and a second... The two belts 84 are connected to both ends of the main shaft 31. The two output shaft ends of the gearbox 82 and the two ends of the main shaft 31 extending out of the first base 3 are each provided with a second pulley 83. The second pulley 83 is rotatably mounted on the main shaft 31 through ball bearings. The mounting plate 71 is fixedly connected to the second pulley 83 near the second base 5 through a connecting flange. After the second motor 81 is reduced in speed by the gearbox 82, it drives the second pulley 83 connected to the mounting plate 71 to rotate through the transmission action of the second belt 84, thereby realizing the forward and reverse rotation of the mounting plate 71.

[0038] Reference Figure 4 , Figure 5 and Figure 6A sliding seat 72, a support 73, and a connecting frame 74 are mounted on the end face of the mounting plate 71 near the second base 5. The connecting frame 74, the sliding seat 72, and the support 73 are all parallel to the axis of the main shaft 31. A wire baffle 741 is mounted on the end of the connecting frame 74 near the I-beam wheel 01. The end of the wire baffle 741 abuts against the end face of the I-beam wheel 01 away from the retaining ring 54. The end of the sliding seat 72 near the I-beam wheel 01 is provided with a first clamping block 721 and a second clamping block 721 for winding the wire. The clamping block 722 includes a first clamping block 721 integrally formed with the sliding seat 72 and a second clamping block 722 hinged to the sliding seat 72. The lengths of the first clamping block 721 and the second clamping block 722 are greater than the width of the connecting plate 52. When the wire laying mechanism 6 pulls the wire to abut against the wire stop plate 741, the first clamping block 721 can abut against the wire as the mounting plate 71 rotates, causing the wire to wrap around the outer ends of the first clamping block 721 and the second clamping block 722.

[0039] Reference Figure 5 A control component 75 is provided on the sliding seat 72. The control component 75 includes a sliding block 751 slidably connected within the sliding seat 72. A first connecting rod 752 is hinged to the end of the sliding block 751 near the first clamping block 721. The end of the first connecting rod 752 away from the sliding block 751 is hinged to the second clamping block 722. A drive block 753 is fixedly connected to the end of the sliding block 751 extending out of the sliding seat 72. A mounting shaft 754 that slides with the sliding seat 72 is fixedly connected to the side of the drive block 753 away from the sliding block 751. A return spring 755 is sleeved on the outer surface of the mounting shaft 754. One end of the return spring 755 abuts against the drive block 753, and the other end abuts against the sliding seat 72. The elastic force of the return spring 755 drives the first clamping block 721 and the second clamping block 722 to remain in an open or closed state. A second drive cylinder 756 for pushing the drive block 753 to move is installed on the first base 3.

[0040] Reference Figure 6 A push rod 731 is slidably connected to the support 73 along its length. The end of the push rod 731 extending out of the support 73 is detachably connected to a clamp 732 by a connecting bolt. A compression spring 733 is sleeved on the outer surface of the push rod 731. An installation groove for placing the compression spring 733 is opened inside the support 73. One end of the compression spring 733 abuts against the push rod 731, and the other end abuts against the inner side wall of the installation groove. The elastic force of the compression spring 733 pulls the clamp 732 to abut against the end of the support 73. A third drive cylinder 734 for pushing the push rod 731 is installed on the first base 3.

[0041] Reference Figure 4The outer surface of the mounting plate 71 is provided with a clearance groove 711. The support 73 and the sliding seat 72 are located on both sides of the clearance groove 711. The first base 3 is equipped with a first driving cylinder 76. The piston rod of the first driving cylinder 76 is fixedly connected to a pneumatic scissor 77. The specific composition and driving principle of the pneumatic scissor 77 are existing technologies and will not be described in detail in this embodiment. When the clearance groove 711 rotates to face the pneumatic scissor 77, the second driving cylinder 756 faces the driving block 753, and the third driving cylinder 734 faces the push rod 731.

[0042] Reference Figure 7 A detection plate 78 is mounted on the outer surface of the mounting plate 71. The detection plate 78 is located on the side of the support 73 away from the sliding seat 72. Four sensors for sensing the position of the detection plate 78 are sequentially mounted circumferentially on the outer surface of the partition plate 2. In this embodiment, all four sensors are proximity sensors. The four sensors are arranged clockwise as sensor 781, sensor 782, sensor 783, and sensor 784. The four sensors transmit the position information of the detection plate 78 to the control system, thereby facilitating the control system to control the wiring mechanism 6 and the knotting machine. The operating states of mechanism 7, first drive mechanism 4 and second drive mechanism 8 are as follows: Specifically, when sensor 781 detects the position of the detection piece 78, the wire is located between the first clamping block 721 and the second clamping block 722; when sensor 782 detects the position of the detection piece 78, the wire is located between the sliding seat 72 and the support 73; when sensor 784 detects the detection piece 78, the wire is located on the side of the support 73 away from the sliding seat 72; when sensor 783 detects the detection piece 78, the clearance groove 711 is directly opposite the pneumatic scissors 77.

[0043] Reference Figures 4 to 7 When the wire on the I-beam 01 is fully laid, the first drive mechanism 4 drives the rotation speed of the main shaft 31 to decrease. Then, the second drive mechanism 8 drives the mounting plate 71 to rotate in the forward direction. The rotation of the mounting plate 71 drives the sliding seat 72, the support 73 and the detection plate 78 to move. When the second sensor 782 detects the position of the detection plate 78, the wire laying mechanism 6 drives the wire to move toward the mounting plate 71 until it abuts against the surface of the wire baffle 741. When the mounting plate 71 rotates to the point where the first clamping block 721 abuts against the wire, as the mounting plate 71 continues to rotate, the wire winds around the outer surfaces of the first clamping block 721 and the second clamping block 722 to form a basic coil. When the mounting plate 71 drives the detection piece 78 to rotate to the fourth sensor 784, the wiring mechanism 6 drives the wire to move towards the I-beam wheel 01 until it is separated from the wire baffle 741. At this time, there is a gap between the end of the wire and the support 73 to prevent the rotation of the mounting plate 71 from causing the wire to wrap around the support 73. When the first sensor 781 detects the position of the detection piece 78, the second drive mechanism 8 stops driving the mounting plate 71 to rotate. At this time, the wire is located between the first clamping block 721 and the second clamping block 722. The wiring mechanism 6 drives the wire to move into the inside of the first clamping block 721 and the second clamping block 722 and abut against the wire baffle 741. Then the second drive mechanism 8 drives the mounting plate 71 to rotate in the opposite direction, and the wire is wound in the opposite direction around the second clamping block 722 and the connection between the support 73 and the clamping block. When sensor 783 detects the position of the detection piece 78, the clearance groove 711 and the pneumatic scissors 77 are aligned. At this time, the second drive mechanism 8 stops the mounting plate 71 from rotating. Simultaneously, the second drive cylinder 756 and the second drive cylinder 756 start synchronously. The piston rod of the second drive cylinder 756 extends and pushes the drive block 753 to move. The drive block 753 overcomes the elastic force of the reset spring 755 and drives the first connecting rod 752 to rotate around the hinge point. The first connecting rod 752 drives the second clamping block 722 to rotate toward the first clamping block 721, thereby achieving the clamping of the wire. The outer wire comes out of the first clamping block 721 and the second clamping block 722 to form a loop. The piston rod of the third drive cylinder 734 extends, overcoming the elastic force of the compression spring 733 to push the push rod 731 to move, so that a gap is formed between the chuck 732 and the support 73 to accommodate the wire. The tensioned wire is inserted into the gap. Then the piston rod of the third drive cylinder 734 retracts, the elastic force of the compression spring 733 is released and pulls the push rod 731 to reset. The chuck 732 moves with the push rod 731 and abuts against the support 73, thereby fixing the wire. After the fixing is completed, the first drive cylinder 76 drives the pneumatic scissors 77 to extend out of the clearance groove 711. The pneumatic scissors 77 cuts the thread between the support 73 and the sliding seat 72. Finally, the first drive mechanism 4 drives the main shaft 31 to rotate in the opposite direction. When the I-beam wheel 01 rotates, it pulls the thread at the closing point of the first clamping block 721 and the second clamping block 722 to achieve thread knotting.

[0044] The implementation principle of Example 1 is as follows: When the wire on the I-beam 01 is fully laid, the first drive mechanism 4 drives the rotation speed of the main shaft 31 to decrease. Then, the second drive mechanism 8 drives the mounting plate 71 to rotate in the forward direction. The rotation of the mounting plate 71 drives the sliding seat 72, the support 73 and the detection plate 78 to move. When the second sensor 782 detects the position of the detection plate 78, the wire laying mechanism 6 drives the wire to move toward the mounting plate 71 until it abuts against the surface of the wire baffle 741. When the mounting plate 71 rotates to the point where the first clamping block 721 abuts against the wire, as the mounting plate 71 continues to rotate, the wire winds around the outer surfaces of the first clamping block 721 and the second clamping block 722 to form a basic coil. When the mounting plate 71 drives the detection piece 78 to rotate to the fourth sensor 784, the wiring mechanism 6 drives the wire to move towards the I-beam wheel 01 until it is separated from the wire baffle 741. At this time, there is a gap between the end of the wire and the support 73 to prevent the rotation of the mounting plate 71 from causing the wire to wrap around the support 73. When the first sensor 781 detects the position of the detection piece 78, the second drive mechanism 8 stops driving the mounting plate 71 to rotate. At this time, the wire is located between the first clamping block 721 and the second clamping block 722. The wiring mechanism 6 drives the wire to move into the inside of the first clamping block 721 and the second clamping block 722 and abut against the wire baffle 741. Then the second drive mechanism 8 drives the mounting plate 71 to rotate in the opposite direction, and the wire is wound in the opposite direction around the second clamping block 722 and the connection between the support 73 and the clamping block. When sensor 783 detects the position of the detection piece 78, the clearance groove 711 and the pneumatic scissors 77 are aligned. At this time, the second drive mechanism 8 stops the mounting plate 71 from rotating. Simultaneously, the second drive cylinder 756 and the second drive cylinder 756 start synchronously. The piston rod of the second drive cylinder 756 extends and pushes the drive block 753 to move. The drive block 753 overcomes the elastic force of the reset spring 755 and drives the first connecting rod 752 to rotate around the hinge point. The first connecting rod 752 drives the second clamping block 722 to rotate toward the first clamping block 721, thereby achieving the clamping of the wire. The outer wire comes out of the first clamping block 721 and the second clamping block 722 to form a loop. The piston rod of the third drive cylinder 734 extends, overcoming the elastic force of the compression spring 733 to push the push rod 731 to move, so that a gap is formed between the chuck 732 and the support 73 to accommodate the wire. The tensioned wire is inserted into the gap. Then the piston rod of the third drive cylinder 734 retracts, the elastic force of the compression spring 733 is released and pulls the push rod 731 to reset. The chuck 732 moves with the push rod 731 and abuts against the support 73, thereby fixing the wire. After fixing, the first drive cylinder 76 drives the pneumatic scissors 77 to extend out of the clearance groove 711. The pneumatic scissors 77 cuts the thread between the support 73 and the sliding seat 72. Finally, the first drive mechanism 4 drives the main shaft 31 to rotate in the opposite direction. When the I-beam wheel 01 rotates, it pulls the thread at the closing point of the first clamping block 721 and the second clamping block 722 to achieve thread knotting. This application achieves automatic thread knotting by setting the thread laying mechanism 6 and the knotting mechanism 7. Compared with the traditional manual knotting operation, it saves time and effort, thereby improving the working efficiency of the take-up machine.

[0045] Example 2 This application discloses a knotting method, including an automatic reel-changing take-up machine, and further includes the following steps: S1: Forward winding: When the wire on the I-beam 01 is fully laid, the first drive mechanism 4 drives the main shaft 31 to reduce its rotation speed. Then the second drive mechanism 8 drives the mounting plate 71 to rotate forward. When the mounting plate 71 rotates to the position where the wire is located between the sliding seat 72 and the support 73, the wire laying mechanism 6 drives the wire to move towards the mounting plate 71 until it abuts against the surface of the wire stop plate 741. As the mounting plate 71 continues to rotate, the wire is wound on the outer surfaces of the first clamping block 721 and the second clamping block 722 to form a basic coil. S2: Displacement adjustment: When the support 73 rotates again to be close to the wire, the wire laying mechanism 6 drives the wire to move towards the I-beam wheel 01 until it is separated from the wire stop plate 741, so as to prevent the wire from getting tangled on the support 73 as the mounting plate 71 rotates. S3: Reverse winding: When the mounting plate 71 rotates to the position where the wire is located between the first clamping block 721 and the second clamping block 722, the second drive mechanism 8 stops driving the mounting plate 71. Then the wire laying mechanism 6 drives the wire to move into the inside of the first clamping block 721 and the second clamping block 722 and abut against the wire stop plate 741. The second drive mechanism 8 drives the mounting plate 71 to rotate in the reverse direction, so that the wire is wound in the reverse direction at the connection between the second clamping block 722 and the support 73 and the clamping block. S4: Clamping into a loop: When the mounting plate 71 rotates to the point where the clearance groove 711 is directly opposite the pneumatic scissors 77, the second drive mechanism 8 stops the mounting plate 71 from rotating. The control component 75 and the third drive cylinder 734 start synchronously. The piston rod of the second drive cylinder 756 extends to push the drive block 753, overcoming the elastic force of the return spring 755 to drive the first connecting rod 752 to rotate, causing the second clamping block 722 to rotate toward and abut against the first clamping block 721, and the outer base coil comes out to form a loop. At the same time, the piston rod of the third drive cylinder 734 extends to push the push rod 731, overcoming the elastic force of the compression spring 733 to create a gap between the clamp 732 and the support 73. The tensioned wire gets stuck in the gap. Then the piston rod of the third drive cylinder 734 retracts, the compression spring 733 resets, and the clamp 732 and the support 73 come into contact, thus fixing the wire. S5: Cutting the thread: The first drive cylinder 76 drives the pneumatic shears 77 to extend from the clearance groove 711 and cut the thread between the support 73 and the sliding seat 72. S6: Tightening and knotting: The first drive mechanism 4 drives the main shaft 31 to rotate in the opposite direction, which drives the I-beam wheel 01 to rotate, tightening the thread at the closing point of the first clamping block 721 and the second clamping block 722, thus completing the knotting of the thread.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
