[0024] In order to facilitate the cloth rolling roller to slide down to the sliding channel, the fixing frame 7 is tilted, and a separation hook for separating the cloth rolling roller is rotatably provided on the fixing frame 7.

[0025] To facilitate the operation of the sliding electric cylinder 24, a photoelectric sensor 27 is provided on the frame 1 and is located at the receiving groove. The photoelectric sensor 27 sends a signal. When the cloth roller 4 falls into the receiving groove, the photoelectric sensor 27 senses the signal and transmits it to the sliding electric cylinder 24. The sliding electric cylinder 24 starts to operate and slowly drives the cloth roller 4 to fall.

[0026] Working principle:

[0027] When the roller needs to be changed, the air cylinder 32 is pushed to work, driving the pushing rod 9 to slide. After the pushing rod 9 slides, it contacts the connecting rod 10, thereby pushing the connecting rod 10 to slide. The connecting rod 10 drives the tooth row 28 to slide, and the tooth row 28 stretches the return spring 31. The tooth row 28 engages with the tooth groove for transmission, driving the blocking block 29 to rotate. The blocking block 29 flips, causing the cloth winding roller 4 to fall out and slide along the fixed frame 7 to the sliding channel mouth, and fall onto the receiving groove of the receiving rod 26. After the photoelectric sensor 27 senses the signal, the sliding electric cylinder 24 is started, driving the cloth winding roller 4 to slide downward in the sliding channel, so that the cloth winding roller 4 slowly falls between the first winding roller 2 and the second winding roller 3, and then the cloth winding machine starts to wind the cloth. When the cloth is rolled, the lifting cylinder 21 returns to its original position, and the telescopic cylinder 22 extends, driving the fixed rod 5 to slide in the first arc groove 11, thereby driving the release plate 12 to swing, so that the sliding channel opening is opened, so that the cloth roller 4 after the cloth is rolled out automatically rolls out to the AGV trolley outside the frame 1. When the lifting cylinder 21 returns to its original position, it pulls the pull rope 19 to move, and the pull rope 19 pulls the push rod 16 to swing outward, so that the push rod 16 drives the swing rod 6 to swing outward, thereby further opening the sliding channel opening, so that the cloth roller 4 can roll out more automatically, and at the same time the push rod 16 swings outward, so that the push rod 16 will not restrict the cloth from rolling outward. When the cloth rolls out, the lifting cylinder 21 rises and the telescopic cylinder 22 returns to its original position, thereby driving the push rod 16 and the release plate 12 to return to their original positions. The push rod 16 then resists the frame 1, thereby pressing the cloth on the cloth roller 4 against the frame 1 to split the cloth. The cloth cutting knife 23 then works to split the cloth. The above operation is then repeated, and a new cloth roller 4 is placed through the sliding channel between the first winding roller 2 and the second winding roller 3.
