[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model embodiment discloses a yarn suction and tail retention mechanism, according to the appendix Figure 1 As shown, it includes a frame 1, a yarn suction mechanism 2, and a yarn blocking mechanism 3. Both the yarn suction mechanism 2 and the yarn blocking mechanism 3 are fixedly connected to the frame 1 to ensure the overall installation stability of the mechanism.

[0019] According to the appendix Figure 2 As shown, the specific structure of the yarn suction mechanism 2 is as follows: The rotary cylinder base 21 is fixedly installed on the inner side of the frame 1 by bolts. The installation method is simple and reliable, and it is convenient for subsequent maintenance and disassembly. A rotary shaft seat 211 is provided on the rotary cylinder base 21. A rotary shaft is inserted into the inner side of the rotary shaft seat 211. The yarn suction turntable 22 is sleeved on the outer side of the rotary shaft, realizing the rotational connection between the yarn suction turntable 22 and the rotary cylinder base 21. A positioning rod 212 is also fixedly connected to the rotary cylinder base 21. The bottom of the yarn suction rotary double-section cylinder 223 is sleeved on the outer side of the positioning rod 212, and the top is sleeved on the top of the yarn suction turntable 22. Through the extension and retraction of the yarn suction rotary double-section cylinder 223, the yarn suction turntable 22 can be driven to rotate around the rotary shaft, realizing the initial adjustment of the yarn suction direction.

[0020] According to the appendix Figure 2 As shown, further, a swing shaft 221 is fixedly connected to the outside of the yarn suction turntable 22, and the yarn suction slide rail 23 is sleeved on the outside of the swing shaft 221 through the outer sleeve block 231 to realize the rotational connection between the two; a connecting plate is provided on the side of the yarn suction slide rail 23 away from the sleeve block 231, and the output end of the swing cylinder 222 is sleeved on the connecting plate. The extension and retraction of the swing cylinder 222 can drive the yarn suction slide rail 23 to swing around the swing shaft 221, realize the secondary fine adjustment of the yarn suction position, and enable the yarn suction nozzle 233 to accurately align with the yarn position.

[0021] According to the appendix Figure 2 As shown, a yarn suction cylinder 232 is connected to the outside of the yarn suction slide rail 23. A slider is sleeved on the output end of the yarn suction cylinder 232. The slider is sleeved on the outside of the yarn suction slide rail 23. The yarn suction cylinder 232 can drive the slider to slide up and down along the yarn suction slide rail 23, thereby driving the yarn suction tube inserted inside the slider to move up and down, adapting to the yarn suction needs of different heights. The bottom end of the yarn suction tube is provided with a yarn suction nozzle 233, and the top end is provided with a yarn suction outlet 234. The yarn suction outlet 234 can be connected to a negative pressure device. The negative pressure causes the yarn suction nozzle 233 to generate suction force, thereby achieving yarn adsorption.

[0022] According to the appendix Figure 2 As shown, a scissor cylinder 235 and a yarn hanging hook 236 are also fixedly connected to the slider. The scissor cylinder 235 is located at the top of the slider and can drive the scissor structure to cut the yarn. The yarn hanging hook 236 is located at the bottom of the slider and behind the yarn suction nozzle 233. After the yarn is cut, it can be directly hung on the yarn hanging hook 236 to ensure that the tail length is consistent and to prevent the yarn from falling off or becoming messy.

[0023] According to the appendix Figure 3 As shown, it is particularly important to emphasize that the yarn-blocking mechanism 3 includes a yarn-blocking support 31, a yarn-blocking cylinder 32, and a yarn-blocking hook plate 33. The yarn-blocking support 31 is fixed to the frame 1 by bolts. The yarn-blocking cylinder 32 is connected to the top of the yarn-blocking support 31. The yarn-blocking hook plate 33 is sleeved on the top of the yarn-blocking support 31 and rotatably connected to it. Simultaneously, the yarn-blocking hook plate 33 is also sleeved on the outside of the output end of the yarn-blocking cylinder 32. Before yarn suction, the yarn-blocking cylinder 32 drives the yarn-blocking hook plate 33 to rotate to the yarn-blocking position to prevent yarn deviation. During yarn suction, the yarn-blocking cylinder 32 drives the yarn-blocking hook plate 33 to rotate to the avoidance position, without affecting the yarn suction operation, thus achieving flexible switching between yarn blocking and yarn release.

[0024] Working principle: First, based on the yarn's position and specifications, the yarn suction rotating base 22 is driven to rotate by the yarn suction rotary cylinder 223 to achieve initial adjustment of the yarn suction direction; then, the yarn suction slide rail 23 is driven to swing by the swing cylinder 222 to perform secondary fine adjustment of the yarn suction position; subsequently, the yarn suction cylinder 232 drives the slider to slide along the yarn suction slide rail 23 to adjust the height of the yarn suction nozzle 233 so that it is aligned with the yarn; at this time, the yarn blocking cylinder 32 drives the yarn blocking hook plate 33 to rotate to the avoidance position, the negative pressure device is activated, and the yarn suction nozzle 233 sucks up the yarn; when the yarn is sucked up in place, the scissor cylinder 235 drives the scissors to cut the yarn, and the cut yarn is hung on the yarn hanging tail hook 236 to complete the yarn suction and tail retention operation; finally, the yarn blocking cylinder 32 drives the yarn blocking hook plate 33 to return to the yarn blocking position, waiting for the next operation.
