Can be when the pile up neatly, pile up neatly bottom plate 15 can be in operation platform's center on the one hand, guarantees that follow-up beating operation keeps unanimous to distance all around, and on the other hand can prevent that pile up neatly bottom plate 15 from taking place to slide when the pile up neatly.

The working principle is as follows:

a preparation stage: an operator firstly places the stacking bottom plate 15 on the bottom plate of the rack 1, lifts the bag body through the stacking manipulator to stack the bag body on the stacking bottom plate 15, and then integrally lowers the stacking frame 2 and covers the stacked bag body through the driving of the lifting motor 1201, the screw rod 1202, the screw rod sleeve 1203 and the like in the lifting mechanism 12;

an angle adjusting stage: the winch 6 is started, the driving rope pulls the movable frame 9 to move to the lowest-layer bag body, the fixed rod 1001 is driven to move upwards while the movable frame 9 moves, so that the connecting rod 14 moves upwards along the oblique guide rod 8 in an oblique mode, the protrusion of the driving gear 1004 rotates along the spiral groove in the fixed rod 1001, the driving gear 1004 is meshed with the driven gear 1003, the driving bevel gear 1008 is driven to rotate through the rotating rod 1006, the driving bevel gear 1008 is meshed with the driven bevel gear 1007, the rotating shaft drives the hammer head mounting rack 1101 to rotate for a certain angle, a certain included angle is formed between the peripheral hammer heads 1102 and the bag body, and the slope is the largest at the moment;

hammering and folding the corner: the servo motor 1103 is started, the hammer 1102 can move up and down through the rotating action of the cam 1104, and then the peripheral side walls of the bag bodies can be beaten, at the moment, the peripheries of the bag bodies are deformed, namely the peripheries of the bag bodies are upwards bulged, the middle of the bag bodies is downwards sunken, so that the bag bodies are approximately funnel-shaped, the upper bag bodies are downwards sunken and deformed, the possibility that the adjacent bag bodies slide in the subsequent moving process is greatly reduced due to the bulged shapes of the peripheries, horizontal blocking is achieved, meanwhile, the gravity of the upper bag bodies needs to be overcome for acting when sliding occurs, and the upper bag bodies are pressed down to the sunken positions through deformation, so that the beaten bag bodies cannot be restored to the original state, and the beaten state is continuously kept;

thus, the winch 5 is started again, so that the driving rope pulls the movable frame 9 to move upwards to the lower end of the second layer of bag body, the operation is consistent with the operation, at the moment, the steering mechanism 10 drives the hammer 1002 to rotate for a certain angle again due to the fact that the driving rope moves upwards again, the slope is reduced at the moment, the component force on the hammering level is increased at the moment, the bag body on the layer is folded upwards on one hand, one hand is gathered towards the middle, the whole volume is reduced compared with the volume of the adjacent lower layer, the whole stacked bag body is stopped at the uppermost end in the above way, the whole stacked bag body forms a frustum shape, the stability after stacking is further increased, and the phenomenon that the bag body slides and falls off when the stacking bottom plate 15 is transported due to the double effects after hammering operation after stacking;

meanwhile, in the hammering process, the regular condition after hammering can be detected by the image sensors 16 connected with the side wall of the movable frame 9, and meanwhile, the leakage condition of the bag body can be monitored in real time.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
