[0024] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0025] At present, the pneumatic drawing-off method is to collect the yarn bobbins with waste yarn to a special workshop, hang on the drawing-off frame, and then release the negative pressure to draw off the waste yarn by compressed air. This method of drawing off the waste yarn by compressed air at least has the following technical problems: a. A special drawing-off workshop needs to be configured, the site occupies a large space, and the flexibility is poor; b. The consumption of compressed air is extremely large, and there is a conversion loss of electric power-compressed energy in the process of producing compressed air by the air pump, so the energy consumption is high; c. A plurality of personnel are needed to cooperate to complete the processes of yarn bobbin carrying, frame hanging, yarn drawing-off, etc., and the labor cost is high; d. It depends on stable air source, and is limited by the layout of the air source, and cannot be operated flexibly with the position of the frame.

[0026] Therefore, there is an urgent need for a yarn frame bobbin tail yarn removal device which does not need to rely on compressed air source, occupies a small space volume, and can be arranged flexibly.

[0027] The overall structure, working principle and technical effects of the yarn frame bobbin tail yarn removal device provided by the present application are described in detail below through embodiments and in conjunction with the drawings.

[0028] The present embodiment provides a yarn frame bobbin tail yarn removal device, which is mainly applied to the process of producing polyester twister fabric, and is used for the drawing-off and removal of the waste yarn (tail yarn 400) on the yarn bobbin 131. After the waste yarn on the yarn bobbin 131 is drawn off, the yarn bobbin 131 can be recycled.

[0029] It should be noted that the yarn frame bobbin tail yarn removal device provided by the present embodiment can also be applied to other working scenes, and is used for realizing the winding work of yarn, and is not limited to the above working scenes.

The winding assembly 220 comprises a main shaft 221, a plurality of supporting rods 222 arranged around the main shaft 221, and a movable flapper 223 detachably connected with the main shaft 221. The first end of the supporting rod 222 is hinged with the main shaft 221 through a first hinge 224, and the second end of the supporting rod 222 is hinged with the movable flapper 223. The driving assembly 300 is configured to drive the main shaft 221 to rotate, so that the main shaft 221 can drive the plurality of supporting rods 222 to rotate and wind the tail yarn 400, and finally wind and draw off all the residual tail yarn 400 on the yarn bobbin 131.

[0031] The yarn frame bobbin tail removal device can place the yarn bobbin 131 loaded with the tail yarn 400 on the frame assembly 100, drive the spindle 221 and the plurality of supporting rods 222 to collect the tail yarn 400, and realize the separation of the tail yarn 400, without compressed air and flexible operation of the frame assembly 100.

[0032] Please continue to refer to Figure 4 and Figure 5 Further, the number of the supporting rods 222 is 4-6, and the plurality of supporting rods 222 are arranged around the spindle 221 to form a cage structure, and the tail yarn 400 can be directly wound on the plurality of supporting rods 222 when the spindle 221 drives the supporting rods 222 to rotate. One end of the supporting rod 222 is hinged to the movable flashboard 223, and the other end is hinged to the spindle 221 through the first hinge 224. It can be understood that the end of the supporting rod 222 close to the first hinge 224 is relatively movable, forming a movable end, and the distance between the movable end and the spindle 221 can be adjusted, so that the supporting rod 222 is relatively inclined in the axial direction, thereby facilitating the unloading of the wound tail yarn 400.

[0033] After the tail yarn 400 is wound, the tail yarn 400, the first hinge 224, the supporting rod 222 and the movable flashboard 223 need to be removed from the spindle 221, the tail yarn 400 is peeled off from the supporting rod 222, and then the first hinge 224, the supporting rod 222 and the movable flashboard 223 are reset to continue the work.

[0034] In order to facilitate the disassembly of the first hinge 224, the supporting rod 222 and the movable flashboard 223, in some embodiments, the winding assembly 220 further comprises a taper sleeve 225, the movable flashboard 223 is sleeved on the taper sleeve 225, and the inner side wall of the taper sleeve 225 is provided with an inclined first matching surface 2251.

[0035] Correspondingly, the two ends of the spindle 221 are tapered, and the tapered outer side wall of the spindle 221 is provided with a second matching surface 2211 matched with the first matching surface 2251.

When the inclined iron 226 is knocked into the taper sleeve 225, since the taper sleeve 225 and the spindle 221 are matched through the first matching surface 2251 and the second matching surface 2211, the inclined iron 226 can provide an axial compression force to the taper sleeve 225, so that the taper sleeve 225 and the spindle 221 can be firmly matched.

[0037] It can be understood that when the taper sleeve 225 and the main shaft 221 are disassembled, the bevel iron 226 is knocked down, and the taper sleeve 225 is pulled in the axial direction.

[0038] Please refer to Figure 5 and Figure 6 During the winding process of the tail yarn 400, one end of the tail yarn 400 needs to be fixed on the support rod 222.

At this time, rotating the main shaft 221 makes the tail yarn 400 wind and tension on the plurality of support rods 222. At this time, the tail yarn fixing rod 227 can clamp one end of the tail yarn 400 under the action of the tension of the tail yarn 400 to fix the tail yarn 400. When the winding of the tail yarn 400 is completed, the distance between the movable end of the support rod 222 and the main shaft 221 is adjusted, so that the support rod 222 is relatively inclined in the axial direction. At this time, the tension of the tail yarn 400 decreases, the head of the tail yarn 400 is released by the tail yarn fixing rod 227, so that the wound tail yarn 400 can be taken off from the support rod 222.
