[0020] The unloading mechanism 2 includes a bracket, a reel, a woven bag roll and a moving wheel, and its function is to unload the woven bag roll. A controller is provided on one side of the mounting plate 1.

[0021] A lifting box 15 is fixedly installed at the bottom of the mounting plate 1, and a first slide groove 16 is opened inside the lifting box 15. A second servo motor 17 is fixedly installed at the bottom inside the first slide groove 16, and a first screw rod 18 is fixedly installed at the output end of the second servo motor 17. A first block 19 is threadedly installed on the outer side of the first screw rod 18, and a stacking support plate 20 is fixedly installed on one side of the first block 19.
