Description

Technical Field

[0001] The invention relates to the technical field of winding mechanisms, and in particular to a winding mechanism for a fiber drawing machine. Background Art

[0002] Chemical fiber is a fiber with textile properties made from natural or synthetic polymer compounds through the processes of preparing spinning solution, spinning and post-processing. The fiber's length, thickness, whiteness, gloss and other properties can be adjusted during the production process. They have the advantages of light resistance, wear resistance, easy washing and drying, and mildew resistance. They are widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulation wires, medical sutures and parachutes.

[0003] In order to improve work efficiency and reduce downtime, such as Figure 1 As shown, the fiber drawing machine in the prior art adopts a fast-rotating driving shaft 90 and multiple groups of winding mechanisms, each of which includes a mounting seat 1, each of which has a mounting roller 2, and each of which is rotatably provided with a connecting roller 3. During operation, the winding drum 5 is connected to the connecting roller 3, and the fiber line is first wound around the winding drum 5 for several turns, and then the entire winding mechanism is moved and the winding drum 5 is abutted against the driving shaft 90 of the drawing machine. The friction between the winding drum 5 and the driving shaft 90 is used to The fiber line is wound by driving the winding drum 5 and the connecting roller 3 to rotate. As the fiber line is wound on the winding drum 5, the fiber line accumulates and gradually becomes thicker until the fiber line abuts against the driving shaft 90. The friction between the fiber line and the driving shaft 90 drives the entire winding drum 5 to continue rotating, thereby winding the fiber line. After the winding of the winding drum 5 is completed, the entire winding drum 5 full of fiber line is removed and replaced with a new winding drum 5 to continue winding. This method will not affect the normal winding of other winding drums 5.

[0004] However, in the above-mentioned prior art, since the driving shaft on the drawing machine keeps rotating rapidly, each time the winding drum abuts against the driving shaft, it will suddenly drive the empty winding drum to rotate rapidly, and the fiber line will be broken by the sudden pulling of the winding drum, which greatly reduces the working efficiency of the winding drum in winding the fiber line. Summary of the invention

[0005] The present invention provides a winding mechanism for a fiber drawing machine, aiming to solve the problem in the related art that each time the winding drum abuts against a driving shaft, the empty winding drum will suddenly be driven to rotate rapidly, and the fiber line will be suddenly pulled by the winding drum and broken, thereby reducing the working efficiency.

[0006] The fiber drawing machine winding mechanism of the present invention comprises a mounting frame and a bobbin, wherein the mounting frame is provided with a fixed roller, and a rotating roller is rotatably provided on the fixed roller, and further comprises:

[0007] A supporting structure, arranged on the rotating roller and the bobbin;

[0008] The transmission mechanism comprises a first transmission ring fixedly arranged on the support structure, a second transmission ring is rotatably arranged on the first transmission ring, a receiving space is enclosed between the first transmission ring and the second transmission ring, the receiving space is filled with transmission oil, a limiting seat is arranged on one side of the second transmission ring, at least four bearing mechanisms are arranged on the limiting seat, and the number of the bearing mechanisms is an even number;

[0009] Each of the bearing mechanisms includes a guide frame that is slidably arranged on a limiting seat with a single degree of freedom, a second elastic member is arranged on the guide frame and the limiting seat, a bearing plate is fixedly arranged on the guide frame, the bearing plate is arc-shaped, all the bearing plates form a circular ring shape, and every two adjacent bearing plates are staggered with each other.

[0010] The fiber drawing machine winding mechanism is controlled to move so that the annular bearing plate is in contact with the driving shaft on the drawing machine, and the driving shaft on the drawing machine drives all the bearing plates to rotate. The bearing plate rotates and drives the second transmission ring to rotate through the limiting seat. The second transmission ring and the first transmission ring rotate relatively, and the transmission oil in the accommodating space is stirred at the same time. Through the transmission of the transmission oil, the second transmission ring gradually accelerates and drives the first transmission ring to rotate. The rotation speeds of the second transmission ring and the first transmission ring are gradually close. The rotation of the first transmission ring drives the support structure to rotate. The rotation of the support structure drives the bobbin to rotate to wind the fiber line until the fiber line is wound to a diameter greater than the diameter of the bearing plate. The wound fiber line is then in contact with the driving shaft on the drawing machine. The driving shaft on the drawing machine starts to drive the bobbin to rotate through the friction between the driving shaft and the fiber line, and the best bobbin winding fiber line state is achieved, which effectively realizes the gradual increase of the bobbin rotation speed, avoids the sudden rapid rotation of the empty bobbin, thereby avoiding the fiber line being broken by the sudden pulling of the bobbin, and greatly improves the working efficiency of the bobbin winding fiber line.

[0011] Preferably, one end of each guide frame is hinged with a pry bar, a strip-shaped sliding hole is opened on the pry bar, a support is movably arranged in the strip-shaped sliding hole, and the support is fixedly set on the second transmission ring. A mounting hole is opened at the center of the fixed roller, and a driving mechanism is arranged in the mounting hole for driving all the pry bars.

[0012] Preferably, the driving mechanism includes a push rod slidably arranged in the mounting hole and a mounting block fixedly arranged in the mounting hole, a third elastic member is arranged between the push rod and the inner wall of the mounting hole, and a wrench is rotatably arranged on the mounting block to abut against the push rod, and the rotation of the wrench can push the push rod to move, and the movement of the push rod can push the pry bar to deflect.

[0013] The pulling part on the pull wrench can push the push rod to move, and the movement of the push rod can push all the pry bars to deflect along the support. Under the action of the lever, all the guide frames are driven to move into the limit seat, so as to achieve the purpose of all the bearing plates to be retracted to the center of the limit seat, which can facilitate the installation and removal of the wire reel.

[0014] Preferably, the wrench has a pulling portion, a pushing portion and a locking portion, and a bearing platform is provided at one end of the push rod close to the mounting block, and the pushing portion abuts against the bearing platform.

[0015] Preferably, a receiving groove is provided on the limiting seat, one end of the push rod away from the mounting block extends into the receiving groove, and one end of the guide frame is placed in the receiving groove.

[0016] Preferably, the supporting structure includes a sleeve slidably arranged on a roller and a slide cylinder sleeved on the sleeve, a first elastic member is arranged on the sleeve and the roller, a first V-shaped groove is formed between the roller and the slide cylinder, a second V-shaped groove is formed between the sleeve and the slide cylinder, elastic support rings are abutted in the first V-shaped groove and the second V-shaped groove, the wire reel abuts on the two elastic support rings, a sealing plate is arranged on the sleeve, and the first transmission ring is arranged on the sealing plate.

[0017] The movement of the push rod can push the entire transmission mechanism to move, and the movement of the transmission mechanism drives the closing plate to move, and the movement of the closing plate drives the sleeve to overcome the elastic force of the first elastic member and move synchronously. At the same time, with the elastic force of the two elastic support rings, the first V-shaped groove and the second V-shaped groove can expand to reduce the diameters of the two elastic support rings, thereby causing the two elastic support rings to move into the first V-shaped groove and the second V-shaped groove respectively, so that the diameters of the two elastic support rings are smaller than the diameter of the inner side of the wire bobbin and lose the abutment force on the wire bobbin, which can facilitate the disassembly of the wire bobbin.

[0018] Preferably, the cross-section of the first transmission ring and the cross-section of the second transmission ring are both C-shaped, at least two first paddles are evenly arranged on the inner side of the first transmission ring, and at least two second paddles are evenly arranged on the inner side of the second transmission ring.

[0019] Preferably, all the bearing mechanisms are evenly distributed along the circumferential direction of the limiting seat, and the outer surface of each bearing plate is provided with a rubber layer.

[0020] By providing the rubber layer, the friction between the bearing plate and the driving shaft on the drawing machine can be increased, thereby improving the transmission effect between the bearing plate and the driving shaft.

[0021] Preferably, an auxiliary mechanism is also included, which includes a limiting opening opened on the mounting frame and a protrusion fixedly arranged on the mounting frame, the inner wall of the limiting opening is hinged with a limiting rod, the limiting rod is provided with a first limiting surface and a second limiting surface, the outer surface of the protrusion is rotatably provided with a rotating plate, and the rotating plate is provided with a protrusion for easy twisting.

[0022] When winding a fiber line with low wear resistance, the driving shaft on the drawing machine will continue to drive all the bearing plates to rotate, so as to drive the entire bobbin to rotate, until the fiber line is rolled up to the outside and piled up to the position of the limiting rod. The fiber line is blocked by the limiting rod and the bobbin can no longer rotate. At this time, the second transmission ring and the first transmission ring rotate relative to each other again, and the second transmission ring is in an idling state, which can reduce the wear on the fiber line with low wear resistance.

[0023] Preferably, a rubber pad abutting against the mounting frame is provided on the rotating plate.

[0024] The beneficial effects of the present invention are:

[0025] 1. Control the movement of the winding mechanism of the fiber drawing machine so that the bearing plate in a circular shape abuts against the driving shaft on the drawing machine, and the driving shaft on the drawing machine drives all the bearing plates to rotate. The bearing plate rotates and drives the second transmission ring to rotate through the limiting seat. The second transmission ring and the first transmission ring rotate relatively, and at the same time, the transmission oil in the accommodating space is stirred. Through the transmission of the transmission oil, the second transmission ring gradually accelerates the rotation of the first transmission ring. The rotation of the first transmission ring drives the bobbin and the roller to rotate through the supporting structure to wind up the fiber line, which effectively realizes the gradual increase of the bobbin rotation speed, avoids the bobbin from breaking due to sudden rapid rotation, and improves the working efficiency of the bobbin winding fiber line;

[0026] 2. Pulling the lever on the wrench can push the push rod to move, and the push rod movement can push all the pry bars to deflect along the support, and drive all the guide frames to move into the limiting seat under the action of the lever, so as to achieve the purpose of all the bearing plates to be retracted to the center of the limiting seat, which can facilitate the installation and removal of the bobbin;

[0027] 3. Controlling the movement of the push rod can push the entire transmission mechanism to move. The movement of the transmission mechanism can drive the sleeve to move synchronously through the sealing plate. At the same time, with the elastic force of the two elastic support rings, the first V-shaped groove and the second V-shaped groove can be expanded to reduce the diameters of the two elastic support rings, so that the two elastic support rings move into the first V-shaped groove and the second V-shaped groove respectively, so that the diameters of the two elastic support rings are smaller than the diameters of the inner side of the wire barrel and lose the abutment force on the wire barrel, which can facilitate the removal of the wire barrel;

[0028] 4. By arranging a rubber layer on the bearing plate, the friction between the bearing plate and the driving shaft on the drawing machine can be increased, thereby improving the transmission effect between the bearing plate and the driving shaft;

[0029] 5. By setting up an auxiliary mechanism, when winding a fiber line with low wear resistance, the driving shaft on the drawing machine will always drive all the bearing plates to rotate, so as to drive the entire bobbin to rotate, until the fiber line is wound to the outside and piled up to the position of the limiting rod. The fiber line is blocked by the limiting rod and the bobbin can no longer rotate. At this time, the second transmission ring and the first transmission ring rotate relative to each other again, and the second transmission ring is in an idling state, which can reduce the wear on the fiber line with low wear resistance.

DETAILED DESCRIPTION

[0046] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0047] like Figures 2 to 12As shown, the first embodiment of the fiber drawing machine winding mechanism of the present invention comprises a mounting frame 10, which can be mounted on the drawing machine to support the fiber drawing machine winding mechanism. A fixed roller 20 is fixedly connected to the mounting frame 10, and a rotating roller 30 is rotatably connected to the fixed roller 20. A supporting structure 40 is arranged on the rotating roller 30, and a bobbin 50 is sleeved on the supporting structure 40. A transmission mechanism 60 is arranged on the supporting structure 40. The transmission mechanism 60 can abut against a driving shaft on the drawing machine, so that the driving shaft on the drawing machine drives the supporting structure 40 to rotate through the transmission mechanism 60. The rotation of the supporting structure 40 can drive the rotating roller 30 and the bobbin 50 to rotate synchronously. The rotation of the bobbin 50 can wind up the fiber line on the drawing machine. A driving mechanism 70 is arranged on the fixed roller 20, and the driving mechanism 70 can drive the transmission mechanism 60 to move in a direction away from the fixed roller 20.

[0048] refer to Figure 2 , Figure 4 and Figure 5 As shown, the fixed roller 20 is fixedly connected to the mounting frame 10 by screws, a mounting hole 21 is opened at the center of the fixed roller 20, the driving mechanism 70 is installed in the mounting hole 21, and the mounting hole 21 includes a first matching portion 211, a second matching portion 212 connected to the first matching portion 211, and a third matching portion 213 connected to the second matching portion 212.

[0049] refer to Figures 2 to 4 as well as Figure 6 and Figure 7 As shown, the roller 30 is rotatably arranged on the surface of the fixed roller 20 through a bearing, and a limiting groove 31 and a first inclined surface 32 are arranged on the roller 30. The supporting structure 40 includes a sleeve 41, a slide 42 and two elastic support rings 43. The sleeve 41 is slidably arranged in the limiting groove 31, and a first elastic member 44 is fixedly connected to the sleeve 41. In this embodiment, the first elastic member 44 is a spring, and one end of the first elastic member 44 is fixedly connected to the inner wall of the limiting groove 31. The sleeve 41 is provided with a second inclined surface 411, and the slide 42 is sleeved on the outer surface of the sleeve 41. A third inclined surface 421 is provided on the side close to the first inclined surface 32, and the first inclined surface 32 and the third inclined surface 421 form a first V-shaped groove. A fourth inclined surface 422 is provided on the side of the slide 42 away from the first inclined surface 32, and the second inclined surface 411 and the fourth inclined surface 422 form a second V-shaped groove. Two elastic support rings 43 are respectively abutted in the first V-shaped groove and the second V-shaped groove. In this embodiment, the elastic support ring 43 is an annular tension spring, and the wire drum 50 abuts on the two elastic support rings 43. One side of the sleeve 41 is fixedly connected to a sealing plate 45 by screws.

[0050] When the closing plate 45 moves, the closing plate 45 can drive the sleeve 41 to overcome the elastic force of the first elastic member 44 and move synchronously. At the same time, with the elastic force of the two elastic support rings 43, the first V-shaped groove and the second V-shaped groove can expand, so that the diameters of the two elastic support rings 43 become smaller, so that the two elastic support rings 43 move into the first V-shaped groove and the second V-shaped groove respectively, so that the two elastic support rings 43 no longer abut against the wire bobbin 50, which can facilitate the disassembly of the wire bobbin 50.

[0051] refer to Figure 2 , Figures 8 to 10 As shown, the transmission mechanism 60 includes a first transmission ring 61 fixedly arranged on the sealing plate 45, the cross section of the first transmission ring 61 is C-shaped, at least two first paddles 611 are evenly arranged on the inner side of the first transmission ring 61, the outer surface of the first transmission ring 61 is rotatably connected to the second transmission ring 62 through a sealing bearing, the cross section of the second transmission ring 62 is C-shaped, at least two second paddles 621 are evenly arranged on the inner side of the second transmission ring 62, and an accommodating space 63 is enclosed between the first transmission ring 61 and the second transmission ring 62, and the accommodating space 63 is filled with transmission oil, and the second transmission ring 62 and the first transmission ring 62 are connected to each other. When the ring 61 rotates relatively, the transmission oil will be stirred. Through the transmission of the transmission oil, the rotational speeds of the second transmission ring 62 and the first transmission ring 61 will gradually approach each other. The first paddle 611 and the second paddle 621 can receive the power of the transmission oil, thereby improving the transmission effect of the second transmission ring 62 and the first transmission ring 61. A limiting seat 64 is fixedly connected to one side of the second transmission ring 62. A receiving groove 641 is provided on the limiting seat 64. At least four bearing mechanisms 65 are provided on the limiting seat 64, and the number of the bearing mechanisms 65 is an even number. All the bearing mechanisms 65 are evenly distributed along the circumferential direction of the limiting seat 64.

[0052] The bearing mechanism 65 can abut against the driving shaft on the drawing machine to transmit the power of the driving shaft on the drawing machine. The power of the driving shaft on the drawing machine can drive the limiting seat 64 to rotate through the bearing mechanism 65. The rotation of the limiting seat 64 drives the second transmission ring 62 to rotate. The rotation of the second transmission ring 62 drives the first transmission ring 61 to rotate through the transmission oil in the accommodating space 63. The rotation of the first transmission ring 61 then drives the supporting structure 40 to rotate through the sealing plate 45.

[0053] Continue to refer Fig. 9 and Fig.10As shown, each bearing mechanism 65 includes a guide hole 651 opened on the limiting seat 64, and a guide frame 652 is slidably connected to the inside of the guide hole 651 with a single degree of freedom. A second elastic member 653 is fixedly connected between the guide frame 652 and the inner wall of the guide hole 651. In this embodiment, the second elastic member 653 is a spring, and the elastic force of the second elastic member 653 can drive the guide frame 652 to move toward the outside of the limiting seat 64. A bearing plate 654 is fixedly connected to the guide frame 652. In this embodiment, the bearing plate 654 is arc-shaped, and the diameter of the bearing plate 654 is larger than the diameter of the wire drum 50, and a rubber layer is provided on the outer surface of the bearing plate 654. When the bearing plate 654 abuts against the driving shaft on the drawing machine, the rubber layer can In order to increase the friction between the bearing plate 654 and the driving shaft on the drawing machine, the transmission effect between the bearing plate 654 and the driving shaft on the drawing machine is improved. One end of the guide frame 652 is placed in the accommodating groove 641. The end of the guide frame 652 placed in the accommodating groove 641 is hinged with a pry bar 655 through a rotating shaft. A strip sliding hole 6551 is opened on the pry bar 655. A support 656 is movably connected in the strip sliding hole 6551, and the support 656 is fixedly connected to the second transmission ring 62 to support the pry bar 655 in an inclined state. It should be noted that all the bearing plates 654 are arranged in a circular ring shape, and every two adjacent bearing plates 654 are staggered with each other to prevent interference between adjacent bearing plates 654 when all the bearing plates 654 move.

[0054] When the wire bobbin 50 is disassembled or assembled, all the pry bars 655 are controlled to move so that all the pry bars 655 are deflected along the support 656. Under the action of the lever, all the guide frames 652 are driven to move toward the limiting seat 64, so as to achieve the purpose of retracting all the supporting plates 654 toward the center of the limiting seat 64. The restriction of the supporting plates 654 on the wire bobbin 50 can be released, so that the inner side of the wire bobbin 50 can pass through the outside of the supporting plates 654 and the wire bobbin 50 can be disassembled or assembled.

[0055] refer to Figure 2 , Figure 4 , Fig.11 and Fig.12As shown, the driving mechanism 70 includes a push rod 71 slidably arranged on the third matching portion 213 and a mounting block 72 fixedly arranged on the first matching portion 211. The end of the push rod 71 close to the mounting block 72 is provided with a bearing platform 711, and the end of the push rod 71 away from the mounting block 72 extends into the accommodating groove 641. It should be noted that a hole for avoiding the push rod 71 is opened at the center of the sealing plate 45, and a third elastic member 73 is provided between the bearing platform 711 and the second matching portion 212. In this embodiment, the third elastic member 73 is a spring, and a wrench 74 that abuts against the bearing platform 711 is rotatably connected to the mounting block 72 through a rotating shaft. The wrench 74 has a pulling portion 741, a pushing top portion 742 and a locking portion 743. The pushing top portion 7 When the locking cam 73 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, so that the locking cam 73 can be unlocked and the locking cam 73 can be unlocked.

[0056] When the locking cam 720 is in the closed position, the locking cam 720 will be in the closed position, and the locking cam 720 will be in the open position when the locking cam 720 is in the closed position. Now the entire transmission mechanism 60 is pushed to move in a direction away from the fixed roller 20, the transmission mechanism 60 moves to drive the sealing plate 45 to move, and the sealing plate 45 moves to drive the sleeve 41 to overcome the elastic force of the first elastic member 44 and move synchronously, and at the same time, with the elastic force of the two elastic support rings 43, the first V-shaped groove and the second V-shaped groove can be expanded to reduce the diameter of the two elastic support rings 43, so that the two elastic support rings 43 move into the first V-shaped groove and the second V-shaped groove respectively, so that the diameter of the two elastic support rings 43 is smaller than the diameter of the inner side of the wire drum 50, and then the wire drum 50 is directly inserted into the wire drum 50 through the outside of the transmission mechanism 60, so that the wire drum 50 is placed outside the two elastic support rings 43;

[0057] Then the wrench 74 is pulled in the opposite direction to reset, and the elastic force of the third elastic member 73 drives the push rod 71 to reset by pressing the bearing platform 711, and the elastic force of the first elastic member 44 drives the sleeve 41 to move, so that the first V-shaped groove and the second V-shaped groove can shrink, thereby forcing the two elastic support rings 43 to deform and increase their diameters, so that the two elastic support rings 43 abut against the inner wall of the wire barrel 50 to support and clamp the wire barrel 50; at the same time, the push rod 71 is reset and freed from the restriction on the pry bar 655, and under the elastic force of the second elastic member 653, all the bearing mechanisms 65 are reset, and all the bearing plates 654 are surrounded into a circular ring shape;

[0058] Subsequently, the winding mechanism of the fiber drawing machine is controlled to move so that the annular bearing plate 654 abuts against the driving shaft on the drawing machine, and the driving shaft on the drawing machine drives all the bearing plates 654 to rotate. The bearing plates 654 rotate and drive the second transmission ring 62 to rotate through the limiting seat 64. The second transmission ring 62 and the first transmission ring 61 rotate relative to each other, which will stir the transmission oil in the accommodating space 63. Through the transmission of the transmission oil, the second transmission ring 62 gradually accelerates and drives the first transmission ring 61 to rotate. The rotation speeds of the second transmission ring 62 and the first transmission ring 61 will gradually approach each other. The first transmission ring 61 rotates and then drives the support structure 40 to rotate through the sealing plate 45. The rotation of the support structure 40 drives the bobbin 50 to rotate to reel in the fiber line until the fiber line is wound to a diameter greater than the diameter of the bearing plate 654. The fiber line abuts against the driving shaft on the drawing machine, and the driving shaft on the drawing machine begins to drive the bobbin 50 to rotate through the friction between the driving shaft and the fiber line. Then, the best state of the bobbin 50 reeling in the fiber line is achieved.

[0059] In the later stage of winding the fiber line by the bobbin 50 in the above embodiment, since the driving shaft on the drawing machine is in direct contact with the fiber line, if the bobbin 50 is not taken out in time when the bobbin 50 is wound to the maximum thickness, the fiber line on the bobbin 50 will slide and rub against the driving shaft on the drawing machine, which can easily cause wear of the fiber line with low wear resistance. In order to overcome the above disadvantages, a second embodiment is proposed to be suitable for fiber lines with low wear resistance.

[0060] like Fig.13 and Fig.14 2 is a second embodiment of the fiber drawing machine winding mechanism of the present invention. The difference from the first embodiment is that the fiber drawing machine winding mechanism further includes an auxiliary mechanism 80.

[0061] The auxiliary mechanism 80 includes a limiting opening 81 opened on the mounting frame 10 and a protrusion 82 fixedly set on the mounting frame 10. The inner wall of the limiting opening 81 is hinged with a limiting rod 83 through a rotating shaft. The limiting rod 83 is provided with a first limiting surface 831 and a second limiting surface 832. The outer surface of the protrusion 82 is rotatably connected to a rotating plate 84 through a bearing. The rotating plate 84 is provided with a rubber pad 841 that abuts against the mounting frame 10. The rubber pad 841 can provide abutting pressure between the rotating plate 84 and the mounting frame 10 to prevent the rotating plate 84 from deflecting due to vibration. The rotating plate 84 is provided with a protrusion that is easy to twist. The limiting rod 83 is rotated to make the first limiting surface 831 on the limiting rod 83 fit against the inner wall of the limiting opening 81. The rotating plate 84 is then twisted through the protrusion to make the rotating plate 84 fit against the second limiting surface 832 on the limiting rod 83, thereby locking the position of the limiting rod 83.

[0062] When winding the fiber line with low wear resistance in this embodiment, the driving shaft on the drafting machine will always drive all the bearing plates 654 to rotate, so as to drive the entire bobbin 50 to rotate, until the fiber line is rolled up to the position where it is piled up outside the limiting rod 83, and the fiber line is blocked by the limiting rod 83 so that the bobbin 50 can no longer rotate. At this time, the second transmission ring 62 and the first transmission ring 61 rotate relative to each other again, and the second transmission ring 62 is in an idling state;

[0063] When the auxiliary mechanism 80 is not in use, the rotating plate 84 is twisted by the protrusion to disengage the rotating plate 84 from the second limiting surface 832 on the limiting rod 83, thereby releasing the lock on the limiting rod 83, and then the limiting rod 83 is moved away from the fiber line to return to the working scene applicable to the first embodiment.
