[0023] The support rod 211 is driven by the support frame 322 to move the unloading shaft 35 to the same height as the unloading shaft 21, and the unloading shaft 35 is driven by the support frame 322 to move the unloading shaft 35 to the same height as the unloading shaft 21. When the unloading shaft 35 rotates to the same axis as the unloading shaft 21, the connecting rod 211 is driven by the support frame 322 to move the unloading shaft 35 to the same height as the unloading shaft 21. The notch on the connecting sleeve 351 is inserted into the connecting sleeve 351, and the connecting sleeve 351 cooperates with the connecting rod 211 to connect the end of the winding shaft 21 with the discharge shaft 35. Then the supporting cylinder 23 drives the supporting swing arm 22 to swing in the direction away from the winding shaft 21, and the connecting sleeve 351 supports the end of the winding shaft 21. At this time, the material roll formed on the winding shaft 21 can be pushed to slide toward the discharge shaft 35 so that it slides onto the discharge shaft 35. Then the rotary drive 36 drives the discharge shaft 35 and the material roll thereon to rotate in the direction away from the winding shaft 21 to above the trolley placed on one side of the base 31. The first motor 37 drives the sliding seat 33 to drive the discharge shaft 35 and the material roll thereon to move downward so that the material roll on the discharge shaft 35 is placed on the trolley. Pulling the trolley can drive the material roll to slide on the discharge shaft 35 so that it is unloaded from the discharge shaft 35, thereby realizing the unloading of the material roll. In the above-mentioned structure and the material roll unloading mechanism 3, it is only necessary to manually push the material roll to slide it from the winding shaft 21 to the unloading shaft 35. The operation is convenient and labor-saving, especially when unloading a material roll with a larger mass, which can greatly save manpower and improve the efficiency of the unloading operation.

[0024] In addition, the winding mechanism 2 is provided with two groups distributed up and down, and two unloading shafts 35 are provided on the support plate 34. The spacing between the two winding shafts 21 is consistent with the spacing between the two unloading shafts 35.

After the material rolls are transferred to the unloading shaft 35, the second motor 40 drives the support plate 34 through the rotating shaft 39 to drive the two unloading shafts 35 to rotate, so that the two unloading shafts 35 and the material rolls thereon are rotated to a position on the same horizontal plane. At this time, the two unloading shafts 35 and the material rolls thereon are driven downward by the first motor 37, so that the material rolls on the two unloading shafts 35 can be placed on the trolley at the same time for unloading, thereby improving the efficiency of the unloading operation.

[0025] In addition, the connecting sleeve 351 is rotatably set on the end of the unloading shaft 35. After the connecting rod 211 is inserted into the connecting sleeve 351 through the notch of the connecting sleeve 351, the connecting sleeve 351 is rotated to rotate it to the bottom of the connecting rod 211, so that the connecting sleeve 351 and the connecting rod 211 cooperate to provide more stable support for the winding shaft 21, ensuring the stability and smoothness of the material roll when transferring from the winding shaft 21 to the unloading shaft 35, and facilitating the operation of pushing the material roll transfer during unloading.
