The spindle outside the twisting machine body is connected to the motor output shaft of the circuit part, and the front end of the spindle is provided with a connector corresponding to the tap switch.

[0003] During the normal operation of the twisting machine, the yarn is wound around the bobbin under the mechanical cooperation of the winding drum and the yarn guide nozzle. A lifting mechanism is provided in the frame, which is used to lift the cradle and the bobbin. The lifting mechanism is connected to power equipment such as a reduction motor. When the thread is broken or the yarn is used up during the spinning and twisting process, the lifting structure will lift the cradle and the bobbin and separate the bobbin from the winding drum to prevent the yarn on the bobbin from continuing to wear and tear.

[0030] The lifting mechanism includes a separator 18, a self-lifting rod 6 and a driving unit, and the driving unit includes a reduction motor 12 and a belt 10. A fixed plate 11 is bolted between the frame 1 near the winding drum 7 and the limit block 4. The reduction motor 12 is fixedly connected to the fixed plate 11 by bolts. The output shaft of the reduction motor 12 is a through shaft, and one end of the through shaft is fixedly connected to a pulley 9 with a frame shaft 29 connected to the winding drum 7. The belt 10 is transmission-connected between the two pulleys 9, and the other end of the through shaft rotates through the fixed plate 11 and is fixedly connected to a rotating wheel 13, and the rotating wheel 13 is fixedly connected to an eccentric shaft 14.

[0031] The frame 1 is rotatably connected to the first rotating shaft 17 and the second rotating shaft 19, and the second rotating shaft 19 is fixedly connected to the lever shifter 20, and the lever shifter 20 is connected to the top rod 21 by bolts, and a circular hole is opened at the end of the lever shifter 20, and a connecting rod 22 is hooked in the circular hole; the first rotating shaft 17 is fixedly connected to the driving plate 16, and a driving rod 15 is hinged on the side of the driving plate 16 away from the first rotating shaft 17, and the free end of the driving rod 15 is hinged to the eccentric shaft 14, and the separator 18 is fixedly connected to the second rotating shaft 19; one end of the self-lifting rod 6 is close to the upper surface of the separator 18, and the other end of the self-lifting rod 6 extends toward the cradle 27. The self-lifting rod 6 near the side of the cradle 27 is provided with a plurality of turns of thread, and the bottom of the cradle 27 is rotatably connected to a nut, and the nut is threadedly connected to the self-lifting rod 6, and the self-lifting rod 6 is integrated with the cradle 27 through the nut.

[0032] The frame 1 above the second rotating shaft 19 is fixedly connected with a magnetic block 25, and the frame 1 below the first rotating shaft 17 is fixedly connected with a fixed block 26, which is rotatably connected to the free end of the connecting rod 22, and the end of the connecting rod 22 close to the fixed block 26 is fixedly connected with a movable rod 23, which is rotatably connected to the fixed block 26, and the free end of the movable rod 23 is fixedly connected with a magnet 24, and when the movable rod 23 is erected, the magnet 24 is close to the magnetic block 25, and the magnet 24 and the magnetic block 25 are adsorbed together to fix the movable rod 23 on the frame 1. When the actual twisting equipment is assembled, a frame 1 is equipped with a plurality of the above-mentioned bobbins 2, cradles 27, winding drums 7, yarn guides 8, lifting mechanisms and other structures.

[0033] The implementation method of this embodiment is as follows: before the normal operation of the device, the operator puts the empty tube bobbin 2 on the cradle 27, and at this time, the bobbin 2 on the cradle 27 is pressed against the surface of the winding drum 7, and the magnet 24 at the end of the movable rod 23 is manually removed from the magnetic block 25, and the movable rod 23 is pulled down and pressed against the yarn under the fixed block 26. Since the movable rod 23 is pressed against the yarn, it is in a tilted state. At this time, the top rod 21 on the lever pusher 20 presses against the self-lifting rod 6 and makes the self-lifting rod 6 in a tilted state, and the bottom end of the self-lifting rod 6 does not contact the upper surface of the separator 18.

[0034] After the spinning and twisting work starts, the winding drum 7 rotates under the drive of the power source at the end of the frame 1, and the through shaft of the reduction motor 12 rotates under the transmission action of the belt 10 and the pulley 9, and the rotating wheel 13 and the eccentric shaft 14 are driven to rotate after deceleration. The driving rod 15 moves slowly with the rotation of the rotating wheel 13, and drives the driving plate 16 to deviate up and down within a certain range. The driving plate 16 drives the first rotating shaft 17 to rotate within a certain angle, and the separator 18 seems to flip up and down with the first rotating shaft 17. At this time, the end of the self-lifting rod 6 is not above the separator 18, so the separator 18 will not contact the self-lifting rod 6.

[0035] After spinning is completed and the yarn breaks, the movable rod 23 falls under the action of its own gravity, and the movable rod 23 drives the connecting rod 22 to rotate, and the connecting rod 22 pulls the lever pusher 20 to rotate. During the rotation of the lever pusher 20, the push rod 21 gradually approaches the second rotating shaft 19, and the end of the self-lifting rod 6 gradually moves to the top of the separator 18. During the flipping process, the separator 18 gradually contacts the end of the self-lifting rod 6, and the separator 18 gradually lifts the self-lifting rod 6. The upper end of the self-lifting rod 6 drives the cradle 27 and the bobbin 2 to move upward and detach from the winding drum 7. The limit block 4 rotates with the cradle 27 due to the lever principle, and the ground of the limit block 4 squeezes the spring 5 and slides on the upper surface of the spring 5. When the self-lifting rod 6 and the cradle 27 are both pushed to the highest point by the separator 18, the spring 5 is just located in the groove of the limit block 4. The separator 18 rotates in the opposite direction and detaches from the self-lifting rod 6. Under the limitation of the spring 5 and the limit block 4, the cradle 27, the bobbin 2 and the self-lifting rod 6 will not reset.

[0036] When the operator is waiting to put in the next empty bobbin 2, the cradle 27, the self-lifting rod 6 and the limit block 4 can be reset. Therefore, when the self-lifting rod 6 and the cradle 27 are lifted, the bobbin 2 and the winding drum 7 will not continue to contact, so that the yarn will not be worn out.

[0037] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
