[0026] Specifically, the release device includes a second fixed rod 13 and a lifting plate 33. A first arc-shaped groove 11 is provided on the frame 1. The second fixed rod 13 is slidably disposed within the first arc-shaped groove 11. Release plates 12 are respectively provided at both ends of the second fixed rod 13. The other end of each release plate 12 is hinged to the frame 1, allowing the second fixed rod 13 to drive the release plate 12 to swing. The second take-up roller 3 is rotatably disposed on the release plate 12. The lifting plate 33 is movably disposed on the frame 1. The upper part has a movable groove, and the end of the second fixed rod 13 extends into the movable groove.

The sliding plate is provided with a horizontally arranged telescopic cylinder 22, and the telescopic rod of the telescopic cylinder 22 is connected to the lifting plate 33.

[0027] In order to facilitate the cutting knife 23 to cut the fabric on the roll roller, a support rod 16 is also included. One end of the support rod 16 is provided on the swing rod 6, and the other end of the support rod 16 is opposed to the frame 1. The upper end of the swing rod 6 is hinged to the frame 1.

The pull rope 19 passes through the tension ring.

[0029] To prevent the fabric roll 4 from being easily damaged when it falls from the sliding channel between the first take-up roller 2 and the second take-up roller 3, a sliding electric cylinder 24 is also included. The sliding electric cylinder 24 is inclined on the frame 1 and located behind the fixed rod 5. The sliding block 25 of the sliding electric cylinder 24 is provided with a receiving rod 26. The receiving rod 26 has a receiving groove. When the fabric roll 4 falls into the sliding channel, the shaft of the fabric roll 4 is located in the receiving groove.

[0030] As attached Figure 3As shown, in order to facilitate the rotation of the second take-up roller 3 and thus facilitate winding, a third roll roller 15 is also included. The third roll roller 15 is rotatably mounted on the frame 1 and passes through the release plate 12. The frame 1 has a second arc-shaped groove 14, through which the shaft of the second take-up roller 3 passes. The second take-up roller 3 is provided with a first gear 35, and the third roll roller 15 is coaxially provided with a second gear and a third gear 36. The second gear meshes with the first gear 35 for transmission, and the third gear 36 transmits power to the drive gear structure on the roll machine. This enables the third roll roller to rotate through its own drive gear structure, which in turn drives the second roll roller to rotate, thereby achieving simplified transmission, reducing manufacturing costs and maintenance rates.

[0031] In order to better open and close the swing rod 6, the lower end of the swing rod 6 is provided with an avoidance notch to prevent interference when the swing rod 6 swings. The release plate 12 is provided with a blocking block 111 and the blocking block 111 is matched with the avoidance notch. The blocking block 111 blocks the avoidance notch when the release plate 12 returns to its original position.

[0032] In order to facilitate the sliding of the fabric roll roller to the sliding channel, the fixing frame 7 is inclined, and the fixing frame 7 is rotatably provided with a separation hook for separating the fabric roll roller.

[0033] To facilitate the operation of the sliding electric cylinder 24, a photoelectric sensor 27 is provided on the frame 1, located at the receiving groove. The photoelectric sensor 27 sends a signal; when the fabric roll 4 falls into the receiving groove, the photoelectric sensor 27 detects the signal and transmits it to the sliding electric cylinder 24, which then starts and slowly drives the fabric roll 4 down.

[0034] Working principle: When it is time to change the roller, the cylinder 32 is activated, which drives the push rod 9 to slide. After the push rod 9 slides, it abuts against the connecting rod 10, thereby pushing the connecting rod 10 to slide. The connecting rod 10 drives the toothed rack 28 to slide, and the toothed rack 28 stretches the return spring 31. The toothed rack 28 meshes with the tooth groove, which drives the blocking block 29 to rotate. The blocking block 29 flips, causing the fabric roll 4 to fall out and slide along the fixed frame 7 to the sliding channel opening, falling onto the receiving groove of the receiving rod 26. After the photoelectric sensor 27 senses the signal, the sliding electric cylinder 24 is activated, driving the fabric roll 4 to slide downward in the sliding channel, so that the fabric roll 4 slowly falls between the first take-up roller 2 and the second take-up roller 3, and then the fabric rolling machine starts to roll the fabric. After the fabric is wound, the lifting cylinder 21 returns to its original position, and the telescopic cylinder 22 extends, causing the second fixed rod 13 to slide within the first arc-shaped groove 11. This causes the release plate 12 to swing, opening the sliding channel and allowing the wound fabric roller 4 to automatically roll out onto the AGV trolley outside the frame 1. When the lifting cylinder 21 returns to its original position, it pulls the pull rope 19, which in turn pulls the abutment rod 16 to swing outward. This causes the abutment rod 16 to swing the swing rod 6 outward, further widening the sliding channel and allowing the wound fabric roller 4 to roll out more automatically. Simultaneously, the outward swing of the abutment rod 16 ensures that it does not restrict the outward rolling of the fabric. After the fabric 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 back to their original positions. Then, the push rod 16 resists the frame 1, thereby pressing the fabric on the roll 4 against the frame 1 to cut the fabric. Then, the cutting knife 23 works to cut the fabric. Then, the above operation is repeated to put a new roll 4 from the sliding channel between the first take-up roller 2 and the second take-up roller 3.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions above are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
