Patent No. CN202411603663.2 discloses an intelligent seed rope braider, which sucks the seeds in the seed feeding hopper onto the disc by vacuum chuck, and the water-soluble tape conveying assembly conveys the water-soluble tape wound together to the seed wrapping assembly. The vacuum chuck rotates the adsorbed seeds to the top of the seed wrapping assembly, so that the seeds fall on the water-soluble tape for wrapping. With the continuous conveying of the water-soluble tape, the seed tape winding assembly winds and binds the water-soluble tape containing seeds, so that the seeds can be fixed in the water-soluble tape to form a seed rope. The seed rope weaving assembly winds the woven seed rope to realize complete weaving production of seed rope. However, the replacement of the rope winding drum in the seed rope winding assembly in the above-mentioned patent needs manual operation, which is time-consuming and laborious. Meanwhile, one end of the rope winding drum is coaxially connected with the rotating shaft, and the other end has no supporting structure. When rotating, it is easy to shake, which affects the straightness, tightness and neatness of the seed rope wound on the rope winding drum. UTILITY MODEL CONTENTS
