[0038] In the embodiment of the present disclosure, a ring array of bolt sleeve conveying frame 3 is arranged on the outside of the inner circulation chain 301 and is rotatably connected through a rotating shaft. The bolt sleeve conveying frame 3 is an L-shaped structure when viewed from the side, and a U-shaped structure when viewed from the top. The bolt sleeve is placed in the groove on the top of the bolt sleeve conveying frame 3 and is conveyed along with the inner circulation chain 301. Both sides of the inner circulation chain 301 are meshed and tightened with a drive shaft 302, and the drive shaft 302 is powered by a motor.

[0039] In the embodiment of the present disclosure, upper supporting slides 401 are arranged at intervals on the lower and upper parts of the lower bolt sleeve supporting frame 4 and slide together, a lower supporting spring 402 is arranged between the upper supporting slide 401 and the lower bolt sleeve supporting frame 4 to provide elastic support, a lower supporting roller 403 is arranged on the top rotating shaft of the upper supporting slide 401 to cooperate with rotation, the rear side of the lower bolt sleeve supporting frame 4 and the electric lifting screw 404 are screwed together to realize the lifting function, the electric lifting screw 404 is rotatably arranged in the middle part of the lower lifting frame 405, the rear side of the lower bolt sleeve supporting frame 4 and the middle part of the lower lifting frame 405 are vertically slidably connected, the lower lifting frame 405 is fixed at the lower part of the main supporting table 2, the lower supporting spring 402 supports the upper supporting slide 401 and the lower supporting roller 403 to move toward one side of the bolt sleeve, the lower supporting roller 403 presses the yarn close to the bolt sleeve, and the lower supporting roller 403 applies pressure to the yarn to enhance the tightness of the yarn and the bolt sleeve.

[0040] Embodiment 2, on the basis of embodiment 1, the middle part of the lower bolt sleeve support frame 4 is disconnected and changed into a sliding connection adjustable mode, the width of the support wheel at the lower part of the lower bolt sleeve support frame 4 is adjusted to adapt to bolt sleeves of different diameters, a sealed box is set on the top of the main support table 2, and the yarn winding output frame 1 is inside the sealed box, and a heating and humidifying device is arranged inside the box to control the temperature and humidity inside the box, control the temperature and use during yarn winding, and reduce the influence of temperature and humidity changes on yarn winding.

[0041] The working principle of this embodiment is as follows: the bolt sleeve is placed in the top groove of the bolt sleeve conveying frame 3, and the bolt sleeve conveying frame 3 moves in a cycle with the inner circulation chain 301. After the bolt sleeve of the bolt sleeve conveying frame 3 moves to the top of the feed inclined plate 206, the bolt sleeve rolls along the feed inclined plate 206 to the middle of the lower bolt sleeve support frame 4, and the lower support roller 403 of the lower bolt sleeve support frame 4 contacts the bolt sleeve. The bolt sleeve conveying frame 3 continues to move downward with the inner circulation chain 301 to complete the reset cycle, and the yarn bends and moves along the winding guide roller 103, and the yarn finally moves to the lower moving frame 106 and the lower connecting frame 104 to be wound. The guide roller 103 moves to the outside of the bolt sleeve, and the telescopic cylinder 203 extends to support the second rotating fixed disk 204 to move close to the bolt sleeve. The bolt sleeve is clamped in the middle by the second rotating fixed disk 204 and the first rotating fixed disk 202 to achieve fixation. Before and after yarn winding, it is necessary to press the thread end to the lower part of the thread through the cooperation of the two outer yarn clamps 205 to achieve the binding of the thread end. The cooperation of the two outer yarn clamps 205 is the same as the structure of the existing yarn winding equipment, and no further description is given. The electric drive module 201 drives the second rotating fixed disk 204, the first rotating fixed disk 202 and the bolt sleeve to rotate to achieve yarn winding. The yarn winding output frame 1 guides the yarn through the yarn winding guide roller 103, and the yarn winding output frame 1 moves horizontally along the ball screw 101, guiding the yarn to perform axial yarn winding operation on the bolt sleeve, and the yarn winding output frame 1 guides the yarn from the head end of the bolt sleeve to the tail end and then moves to the head end to complete the yarn winding work. After the yarn winding is completed, the lower bolt sleeve support frame 4 moves downward with the electric lifting screw 404, and the bolt sleeve at the top of the lower bolt sleeve support frame 4 moves to the top of the lower discharge plate 304 for output work. The vertical up and down movement of the lower bolt sleeve support frame 4 realizes the feeding and discharging operation of the bolt sleeve, and the lower support spring 402 supports the upper support slide The bracket 401 and the lower support roller 403 move toward one side of the bolt sleeve, and the lower support roller 403 fits the bolt sleeve and the external yarn. The lower support roller 403 presses the yarn close to the bolt sleeve, and the lower support roller 403 applies pressure to the yarn to make it close to the bolt sleeve, which helps to ensure the tightness of the yarn winding. When the yarn gradually increases during the winding process, the lower support roller 403 moves away from the bolt sleeve with the upper support carriage 401, adapting to the thickness change after the yarn increases, ensuring that the yarn can always maintain a good winding state during the entire winding process, thereby improving the quality and stability of the bolt sleeve winding.

[0042] The bolt sleeve conveying frame 3 is used to convey the bolt sleeves, and the lower discharge plate 304 below the bolt sleeve conveying frame 3 is responsible for outputting the bolt sleeves after winding. The bolt sleeve conveying frame 3 and the lower discharge plate 304 are vertically stacked. Compared with the existing bolt sleeves that are conveyed and output from both sides, the space occupancy rate is significantly improved, the space utilization rate is effectively improved, the space requirement is greatly reduced, the task of adding winding equipment in the existing factory building is met, and more efficient operation is achieved in a limited space, which further reduces the site restriction problem caused by the equipment layout, provides strong support for the compactness and efficiency of the production process, and adapts to the expansion of the enterprise's production scale and the update and upgrade of equipment;

[0043] The middle support spring 107 supports the lower moving frame 106 to move upward and close to the lower connecting frame 104. The yarn winding guide roller 103 of the lower moving frame 106 and the lower connecting frame 104 approaches and clamps the yarn in the middle, increasing the resistance of the yarn during movement, so that the yarn can fit more closely to the outside of the bolt sleeve, thereby significantly improving the fit between the yarn and the bolt sleeve, and also avoiding the situation that the yarn and the yarn winding guide roller 103 are separated during the horizontal movement of the yarn winding output frame 1. At the same time, the lower limit nut 108 moves vertically along the thread of the lower vertical sliding column 105, and the lower limit nut 108 moves to extend or compress the length of the middle support spring 107. Since the middle support spring 10 The length change of 7 will directly affect the size of its supporting force on the lower moving frame 106. When the lower limit nut 108 moves to compress the middle support spring 107, the supporting force of the middle support spring 107 on the upper lower moving frame 106 will increase. When the lower limit nut 108 moves to expand the length of the middle support spring 107, the supporting force of the middle support spring 107 on the upper lower moving frame 106 will decrease. Therefore, by adjusting the lower limit nut 108, the supporting force of the middle support spring 107 on the lower moving frame 106 can be accurately controlled, thereby realizing the height adjustment of the middle yarn clamping force, which can adapt to the yarn winding requirements of bolt sleeves and yarns of different specifications, and further improve the versatility and adaptability of the equipment.
