[0040] Two symmetrical groups of telescopic drive groups 5 are provided on both sides of the middle part of the twisting frame 2, which are connected to the clamping twisting block 7 for transmission. After the yarn is used up, the tail end of the yarn can be clamped and fixed by driving the clamping twisting block 7, thereby avoiding the separation of the yarn from the textile equipment. At the same time, after the defense line is clamped, the magnetic transmission mode of the telescopic drive group 5 can be used to split and move up the yarn, thereby realizing the function of overlapping and twisting of two groups of yarns. In the process of twisting the defense line, the thread ends are twisted by two groups of clamping twisting blocks 7, thereby ensuring the strength and integrity of the twisting of the thread ends.

[0041] The use process of the yarn winding end self-twisting device of a textile equipment provided by the present invention is as follows: When it is necessary to twist the thread ends to connect the spinning threads, the textile equipment will automatically stop after the used spinning thread tail end is sent out through the last circle of the spinning reel 12. When the equipment stops, the second motor 513 will start, driving the telescopic drive group 5 to start a stage of driving the clamping twisting block 7 to move. The clamping twisting block 7 will be driven to clamp the old thread tail end 14. At this time, the new spinning reel 12 is taken out and placed above the spinning installation roller 11. After that, the end of the defense line wound outside the spinning reel 12 will be affected by gravity and located inside the new line entrance 22.

[0042] Start the first motor 41. The start of the first motor 41 will drive the driving gear 42 connected to its output end to rotate. The rotation of the driving gear 42 will drive the transmission gear block 35 meshing with it to move. The movement of the transmission gear block 35 will drive the rotation displacement rod 31 to rotate. The rotation of the rotation displacement rod 31 will drive the clamping installation shaft 32 connected to the other end thereof to move and drive the changing gear 44 and the driven gear 45 installed on the outer wall of the rotation displacement rod 31 to rotate.

[0043] The movement of the clamping and mounting shaft 32 will drive the clamping block 33 to rotate and move in a circular shape.

[0044] When the reversing gear 44 rotates during the rotation of the rotary displacement rod 31, since it meshes with the fixed gear 43, the reversing gear 44 will rotate. The rotation of the reversing gear 44 will drive the driven gear 45 meshing with it to rotate. The rotation of the driven gear 45 will drive the transmission toothed belt 47 to move. The movement of the transmission toothed belt 47 will drive the transmission gear 46 sleeved with it to rotate. The rotation of the transmission gear 46 will drive the gripper mounting shaft 32 to rotate. And due to the setting of the reversing gear 44, the rotation direction of the gripper mounting shaft 32 can be opposite to that of the rotary displacement rod 31.

[0045] At the same time, since the reversing gear 44, the driven gear 45, and the transmission gear 46 are gears of the same size and number of teeth, their transmission strokes are the same. Since the reversing gear 44 is meshed and connected with the fixed gear 43 installed at the center of the rotary displacement rod 31, the rotation stroke of the gripper mounting shaft 32 is the same as the rotation angle of the rotary displacement rod 31, and the gripper blocks 33 connected to both sides of the middle part of the gripper mounting shaft 32 can always be in a horizontal state.

[0046] Before the first motor 41 is driven, the telescopic drive group 5 and the clamping and twisting block 7 connected inside the gripper block 33 will start. The start of the telescopic drive group 5 will drive the driving gear 514 to rotate through the second motor 513. The rotation of the driving gear 514 will drive the transmission toothed ring 512 meshing with it to rotate. The rotation of the transmission toothed ring 512 will drive the transmission sleeve ring 511 to rotate. The rotation of the transmission sleeve ring 511 will drive the internally threaded sleeve rod 51 to rotate. The rotation of the internally threaded sleeve rod 51 will drive the threaded sleeve rod 52 meshing with its inner wall to rotate.

[0047] And since the inner wall of the threaded sleeve rod 52 is magnetically adsorbed and attached to the outer wall of the limiting rod 53 through the outer magnetic rod 521 and the inner magnetic rod 531, and at the same time, the magnetic rods are clamped and connected through the meshing ring 522 and the meshing groove 532, the threaded sleeve rod 52 and the limiting rod 53 can form a magnetic adsorption connection. When the transmission force between the internally threaded sleeve rod 51 and the threaded sleeve rod 52 is less than the magnetic adsorption force between the outer magnetic rod 521 and the inner magnetic rod 531, the rotation of the internally threaded sleeve rod 51 will drive the threaded sleeve rod 52 and the limiting rod 53 to move into the gripper inner embedding groove 25.

[0048] When the limiting rod 53 moves, it will push the C-shaped frame 533 connected to its end to move. Since the two ends of the C-shaped frame 533 are limited and slide on the inner wall of the gripper inner embedding groove 25, its movement will be in a horizontal direction. The movement of the C-shaped frame 533 will drive the clamping and twisting block 7 connected to the middle part of it to move. The movement of the clamping and twisting block 7 will drive the rubber twisting belt 77 sleeved on its outer wall to move. When the two clamping and twisting blocks 7 move to the middle of the twisting combination port 21 at the same time, the new wire head end 13 will be clamped and fixed by the rubber twisting belt 77.

[0049] At this time, the first motor 41 will start, and the second motor 513 will continue to work. When the second motor 513 works, it will start the second stage of the telescopic drive group 5. When the telescopic drive group 5 starts the second stage, since the two rubber twisting belts 77 are in contact, the clamping twisting block 7 cannot continue to advance. Then, the rotational force exerted by the internal thread sleeve rod 51 on the thread sleeve rod 52 will be greater than the magnetic force between the outer magnetic rod 521 and the inner magnetic rod 531. Therefore, the internal thread sleeve rod 51 will drive the thread sleeve rod 52 to rotate, causing the thread sleeve rod 52 to slide and rotate on the outer wall of the limit rod 53. At this time, the rotation of the thread sleeve rod 52 will drive the second tooth ring 523 at its end to rotate. The rotation of the second tooth ring 523 will drive the second gear 762 meshing with it to rotate. The rotation of the second gear 762 will drive the second bevel gear 761 coaxially connected to it to rotate. The rotation of the second bevel gear 761 will drive the first bevel gear 75 to rotate. The rotation of the first bevel gear 75 will drive the first gear 74 coaxially connected to it to rotate. The rotation of the first gear 74 will drive the fixed tooth belt 78 meshing with it to move. The movement of the fixed tooth belt 78 will drive the rubber twisting belt 77 connected to it to move. When the two rubber twisting belts 77 move, the thread held in the middle will rotate.

[0050] It should be noted that: the rotation directions of the two rubber twisting belts 77 are different. Therefore, when the rubber twisting belts 77 move, the thread held in the middle can be rotated and split.

[0051] It should be noted that: the driving forces of the second motors 513 driving the two rubber twisting belts 77 are different. The driving force stroke of one of the second motors 513 is 1.2 times that of the driving force of the other second motor 513. And because the rotation strokes of the two second motors 513 are different, the thread between the rubber twisting belts 77 will gradually rotate and split and move downward. When the first motor 41 drives the rotary displacement rod 31 to rotate to the other end, the new head end 13 held between the two rubber twisting belts 77 will be pulled above the two clamping twisting blocks 7 in the middle of the twisting frame 2.

[0052] At this time, since the rotational speeds of the rubber twisting belts 77 between the two clamping twisting blocks 7 inside the clamping block 33 are different, after the new head end 13 rotates and splits, when the rotary displacement rod 31 rotates to the limit position, the new head end 13 will break away from the rubber twisting belts 77. The new head end 13 will be pushed by the rubber twisting belts 77, causing the split new head end 13 to fit above the clamping twisting block 7 between the new head end 13 and the twisting frame 2.

[0053] At this time, starting the telescopic drive group 5 inside the twisting combination port 21 can make the old wire head end rotate reversely, cause the old wire head end to crack, and move above the clamping twisting block 7, overlapping with the new wire head end 13 that falls between the rubber twisting belts 77. The rubber twisting belts 77 inside the twisting combination port 21 rotate, and the two groups of spun yarns will be combined and twisted together. When the wire head twisting is completed, reversely starting the second motor 513 can directly make the clamping twisting block 7 inside the twisting combination port 21 contract into the clamping groove 25 to complete the twisting work.

[0054] It should be noted that: the clamping twisting block 7 inside the twisting combination port 21 drives the rubber twisting belt 77 to rotate at the same speed of 1.2 times, and the direction in which the rubber twisting belt 77 drives the old wire head end to move is upward. Therefore, after the new wire head end 13 falls between the rubber twisting belts 77, the old and new wire heads can be twisted together.

[0055] Moreover, since the rubber twisting belt 77 inside the twisting combination port 21 is in an open shape, it can ensure that the new wire head end 13 accurately falls inside it, and at the same time ensure that the wire head is always between the so-called twisting belts during the twisting process for twisting, ensuring the twisting effect.

[0056] It should be noted that: when starting the rotation and movement of the wire clamping claw 3, the telescopic drive group 5 inside the twisting combination port 21 can be pneumatically actuated at the same time to reversely rotate and crack the old wire head end in advance. After the new wire head end 13 falls between the rubber twisting belts 77, the wire head twisting work can be directly carried out, improving the twisting efficiency.
