[0025] like Figure 4 and Figure 5 As shown, a plurality of tensioning rollers 9 are fixedly installed between the two side plates 2. The tensioning rollers 9 ensure that the garbage is always in a tensioned state to prevent the garbage from loosening and affecting the cutting of the garbage bag.

[0026] like Figure 1 - Figure 3 As shown, a U-shaped support frame 15 is fixedly connected to the middle part of the upper end of the base 1, a telescopic cylinder 16 is fixedly installed on the upper end of the U-shaped support frame 15, and a lifting plate 22 is fixedly connected to the output end of the telescopic cylinder 16.

When deviation occurs, the distance sensor 3 sends a signal, the electric telescopic rod 6 is started, and the electric telescopic rod 6 pushes the mounting frame 4 to rotate in the opposite direction of the deviation of the garbage bag. The friction between the correcting roller 5 and the garbage bag guides the garbage bag to the correct direction to achieve deviation correction. The driving device 13 is turned on, so that the driving roller 12 drives the garbage bag to move to the conveyor belt 19, and then the telescopic cylinder 16 is turned on, so that the heating strip 23 and the cutting knife 24 cut the garbage bag into sections. After a stack is piled on the conveyor belt 19, the equipment in the handle pressing device 17 is turned on, and the handle is cut out of the garbage bag. The conveyor belt 19 is turned on and the garbage bag is moved to the other end of the conveyor belt 19.
