Release plates 12 are respectively provided at both ends of the fixing rod 5, and the other end of the release plate 12 is hinged to the frame 1 so that the fixing rod 5 can drive the release plate 12 to swing, and the second winding roller 3 is rotatably arranged on the release plate 12, and the lifting plate 33 is movably arranged on the frame 1, and a movable groove is provided on the lifting plate 33. The end of the fixing rod 5 extends into the movable groove, and a lifting spring 34 is provided on the fixing rod 5, and the other end of the lifting spring 34 is provided on the lifting plate 33. A sliding plate is provided on the frame 1, and the sliding plate is located on the side of the frame 1. A lifting cylinder 21 is provided on the frame 1, and the extending rod of the lifting cylinder 21 is connected to the sliding plate. A telescopic cylinder 22 is provided laterally on the sliding plate, and the telescopic rod of the telescopic cylinder 22 is connected to the lifting plate 33.

[0022] In order to facilitate the cloth cutting knife 23 to cut the cloth on the cloth roller, it also includes a push rod 16, one end of which is arranged on the swing rod 6, and the other end of the push rod 16 resists the frame 1. The upper end of the swing rod 6 is hinged to the frame 1, and the frame 1 is provided with an outward swing device for driving the push rod 16 to swing outward.

[0023] Specifically, the outward swing device comprises a first pulley 17 and a second pulley 18, wherein the first pulley 17 is arranged on the telescopic cylinder 22, and the second pulley 18 is arranged on the push rod 16. A pull rope 19 is provided on the telescopic cylinder 22, and the other end of the pull rope 19 is provided on the push rod 16.

[0024] In order to prevent the cloth rolling roller 4 from being damaged when it falls from the sliding channel to between the first winding roller 2 and the second winding roller 3, a sliding electric cylinder 24 is also included. The sliding electric cylinder 24 is tilted on the frame 1 and is located behind the fixed rod 5. A receiving rod 26 is provided on the sliding block 25 of the sliding electric cylinder 24. The receiving rod 26 is provided with a receiving groove. When the cloth rolling roller 4 falls into the sliding channel, the axis of the cloth rolling roller 4 is located in the receiving groove.

[0025] As attached Figure 3As shown, in order to facilitate the rotation of the second winding roller 3 and thus facilitate winding, a third cloth winding roller 15 is also included, and the third cloth winding roller 15 is rotatably arranged on the frame 1, and the third cloth winding roller 15 passes through the release plate 12, and a second arc-shaped slot 14 is opened on the frame 1, and the axis of the second winding roller 3 passes through the second arc-shaped slot 14, and the second winding roller 3 is provided with a first gear 35, and the third cloth winding roller 15 is coaxially rotatably provided with a second gear and a third gear 36, wherein the second gear is meshed with the first gear 35 for transmission, and the third gear 36 is transmitted with the driving gear structure on the cloth winding machine, so that the third cloth winding roller is driven to rotate by its own driving gear structure, and then the second cloth winding roller is driven to rotate, thereby achieving streamlined transmission, which not only reduces manufacturing costs but also reduces maintenance rate.

[0026] In order to better open and close the swing rod 6, an avoidance gap is opened at the lower end of the swing rod 6 to prevent interference when the swing rod 6 swings. A blocking block 111 is provided on the release plate 12 and the blocking block 111 matches the avoidance gap setting. The blocking block 111 blocks the avoidance gap when the release plate 12 returns to its original position.

[0027] 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.

[0028] 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.

[0029] Working principle:

[0030] 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.
