The movement rod 18 moves under the drive of the hydraulic cylinder 19, so that the platform realizes up and down movement.

[0045] As shown in Figure 5As shown, two flap support brackets 22 are welded onto the lifting platform 21, and are connected to the left flap 23 via the flap support brackets 22. Similarly, two flap support brackets 22 are welded onto the left flap 23. The right flap 24 is also connected to the left flap 23 via flap support brackets 22. The left flap 23, right flap 24, and flap support brackets 22 are connected by flap hinges 35. The flap hinge of the left flap is located at the leftmost top of the lower flap support, and the flap hinge of the right flap is located at the rightmost top of the upper flap support.

[0047] A working method of an automatic cotton bale unpacking machine, such as... Figure 1 As shown, when cotton bale 1 is conveyed from the conveyor belt to the tilting frame 8, it is in a horizontal position. The tilting frame 8 is rotated by a corresponding angle under the drive of the tilting hydraulic cylinder 5, so that the diagonal of cotton bale 1 is perpendicular to the ground. Figure 2 As shown. Then, the rotated cotton bale 1 needs to be conveyed to the upper and lower inclined plates of the cutting mechanism. The tilting hydraulic cylinder 3 in the tilting mechanism drives the tilting plate 4, so that the cotton bale 1 slides from the flipping frame 8 onto the lower inclined plate 33. The roller 7 on the flipping frame 8 helps the cotton bale 1 slide down, so that the tilting plate 4 can transport the cotton bale 1 onto the lower inclined plate 33 of the cutting mechanism without rotating a large angle.

[0048] like Figure 3As shown, after the cotton bale 1 falls onto the inclined plate of the cutting mechanism, the slide rail motor 16 starts, driving the slide rail gear 13 to rotate. The slider 11 moves forward under the drive of the gear 13, and the scissor lift platform also moves forward under the drive of the slider 11. When the cotton bale 1 moves directly below the blade holder 37, the slide rail motor 16 stops, and the hydraulic cylinder 19 of the scissor lift platform drives the moving rod 18 to start moving, causing the platform 21 to move upward. During the upward movement of the cotton bale 1, the side blade 39 cuts open both sides of the cotton bale 1. The rotating wheel motor 46 is in the normally open state, and the small gear 44 drives the rotating wheel 41 to rotate, so that the rotating blade 40 is in working state. When the lift platform 21 rises to the corresponding position, the rotating blade 40 cuts the binding rope and cuts open the upper side of the cotton bale 1. After the bag is cut, the scissor lift platform 21 descends back to its original position. The slide rail motor 16 starts again, and stops rotating when it moves to the end of the slide rail. The suction cup 31 is activated (using an external vacuum pump, a common setup, not described in detail), causing the outer packaging bag of cotton bale 1 to adhere to the suction cup 31. The driving rod of the parallelogram mechanism 26 on the inclined plate, driven by the motor 28, begins to move, causing the upper inclined plate 30 to rotate to both sides at a certain angle under the drive of the driven rod of the parallelogram mechanism 26. This causes the outer packaging bag of cotton bale 1 to leave along with the upper inclined plate, exposing the cotton portion of cotton bale 1. The left flip plate 23, driven by the left flip plate hydraulic cylinder 36, rotates to the left. At a certain angle, the cotton slides down to the left under gravity for conveying, separating the cotton from the outer packaging bag. The left flip plate 23 returns to the horizontal position, the suction cup 31 closes, and the right flip plate 24, driven by the right flip hydraulic cylinder 34, rotates to the right at a certain angle, causing the packaging bag and binding rope remaining on the inclined plate to slide down, completing the collection of waste materials. Finally, it resets to begin unpacking the next cotton bale.

[0049] Using compressed cotton bales as the target, and leveraging its excellent mobility, this system can complete tasks such as bag grabbing, rope cutting, bag breaking, collection, and transportation. It represents the final step in the process of feeding the compressed cotton into the filter rod forming machine. For compressed cotton bales, a sufficiently large opening needs to be cut into the surface of the bale to remove the cotton inside completely. This solution fills a gap in domestic technology for the automatic unpacking of bulk materials and plays a crucial role in the filter rod forming process.

[0050] This invention is not limited to the preferred embodiment described above. Anyone inspired by this invention can derive other various forms of automatic unpacking machines for compressed cotton bales and their operating methods. All equivalent variations and modifications made within the scope of the claims of this invention should be considered within the scope of this invention.
