damping mechanisms (4) are uniformly arranged below the mounting plate (3); the damping mechanism (4) comprises an arc-shaped plate (41), a roller (42) and a mounting frame (43); the two arc plates (41) are arranged into a group, every two arc plates (41) are in cross connection, and the lower ends of the arc plates (41) are in sliding contact with the outer surface of the roller (42); a torsion spring is arranged in the roller (42), and two ends of the roller (42) are rotatably connected to the mounting rack (43) through a rotating shaft; the lower end of the mounting rack (43) is fixedly connected to the inner lower surface of the box body (1);

the damping mechanism (4) further comprises a separation disc (44); the diameter of the disc from the outer end to the inner end of the separation disc (44) is set to be from large to small, and the separation disc (44) is uniformly and fixedly arranged on the outer surface of the roller (42);

the lower surface of the box cover (2) is provided with a second fixing mechanism (6); the second fixing mechanism (6) comprises a protection plate (61), a threaded paper plate (62) and a clamping groove (63); the protection plates (61) are uniformly and symmetrically fixedly arranged on the lower surface of the box cover (2), and the lower surface of the inner side of each protection plate (61) is fixedly connected with a threaded paperboard (62); the threaded paperboard (62) is in a hook shape, and a clamping groove (63) is formed in the outer wall of the lower end of the threaded paperboard (62);

when the automatic can packing machine works, cans are placed on the bearing plate (51) of the first fixing mechanism (5) in the box body (1), under the action of gravity of the can body, the bearing plate (51) is downwards extruded, namely the elastic telescopic rod (52) is compressed, when the elastic telescopic rod (52) cannot be continuously downwards compressed, the bottom plate (53) is pushed to move downwards, namely extrusion force is generated on the rubber air bag (54), when the rubber air bag (54) is extruded, the air pressure in the rubber air bag is gradually increased, the inner air pressure can be conveyed outwards through the arc-shaped pipe (55), the arc-shaped telescopic plate (56) is connected in the arc-shaped pipe (55) in a sliding mode through the spring, namely when the air pressure in the rubber air bag (54) is increased, the arc-shaped telescopic plate (56) is pushed to slide outwards and finally wrap and fix the bottoms of the cans, namely, the folding plate (57) at the upper ends of the arc-shaped telescopic plate (56, when the box body (1) is subjected to larger vibration force, the shaking action at the bottom of the can is greatly reduced due to the winding of the folding plate (57), and the contact part between the folding plate (57) and the inner surface of the arc-shaped expansion plate (56) is fixedly connected, namely, the fixed area of the folding plate (57) cannot shift, when the can is transported to a bumpy road section, the mounting plate (3) can be driven to slide up and down in the box body (1) due to the fact that a vehicle shakes violently, an extrusion force can be generated on the arc-shaped plate (41) when the mounting plate (3) slides down, when the extrusion force applied to the arc-shaped plate (41) is larger and larger, the arc-shaped plate can be fixed to the outer side through a cross point, the lower end of the arc-shaped plate (41) is contacted with the outer surface of the roller (42), namely, the roller (42) can be pushed to rotate along with the pressing of the arc-shaped plate (, therefore, when the roller (42) rotates to a certain degree, the rotating force is reduced, a reverse thrust is given to the arc-shaped plates (41), namely, a mutual thrust is formed between the mounting plate (3) and the roller (42) through the arc-shaped plates (41), so that the vertical sliding amplitude of the mounting plate (3) is rapidly reduced, meanwhile, when the arc-shaped plates (41) move downwards under extrusion force and slide on the roller (42), the isolation discs (44) on the roller (42) can form an isolation effect between the crossed arc-shaped plates (41), and simultaneously, a traction force can be given to the arc-shaped plates (41) when the roller (42) rotates, the arc-shaped plates (41) are guided to slide uniformly to two sides, so that the lower parts of the arc-shaped plates (41) are uniformly stressed, and because the isolation discs (44) are arranged to be gradually reduced from the outside to the inside diameter, the friction force between the middle parts of the roller (42) and the arc-shaped plates (41, make the gliding and the return of arc (41) more natural, torsional spring in roller (42) receives torsion effect to kick-back simultaneously and can also guide arc (41) quick return, put into box (1) back when the can, can put into box (1) through pull rod (21) box (1) with case lid (2), when putting into box (1) in case lid (2), guard plate (61) can be located the upside of can, and threaded paper board (62) in guard plate (61) can receive the extrusion force of can bowl cover by the compression, and set up to colluding the type because of threaded paper board (62), then threaded paper board (62) can be extruded to the outside by the level, gradually by the extrusion open when threaded paper board (62), slowly imbed draw-in groove (63) on the threaded paper board (62) promptly of can, the realization is fixed to the can upper end.
