The winding mechanism 5 includes a slide 501, and the slide 501 is symmetrically opened on one side of the mounting seat 3. At the end, the inner wall of the slide groove 501 is slidably connected to the slide plate 502, and the outer wall of the slide plate 502 is rotatably connected to the connecting block 503, the outer wall of a slide plate 502 is installed with a first motor 504, the connecting block 503 is connected to the output end of the first motor 504, the outer wall of the mounting seat 3 is installed with a second motor 505, the output end of the second motor 505 is connected to the first threaded rod 506, the first threaded rod 506 is rotatably connected to the inside of the mounting seat 3 and passes through the slide plate 502, and the first connecting grooves 507 are provided at both ends of the winding drum 4.

[0029] In this embodiment: when installing the winding drum 4, the winding drum 4 is placed between the two connecting blocks 503, and the second motor 505 is started. The second motor 505 drives the first threaded rod 506 to rotate, and the first threaded rod 506 rotates to drive the slide plate 502 to move in the slide groove 501. The two slide plates 502 move closer to each other, driving the connecting block 503 to move and insert into the first connecting groove 507, thereby positioning the winding drum 4. At this time, the first motor 504 can be started, and the first motor 504 drives the connecting block 503 to rotate when it rotates. The connection block 503 rotates and drives the winding drum 4 to rotate, and the fabric is wound up.
