When the lifting bar 513 lifts the cartridge against the nozzles 522, the nozzles 522 catch the closure plate 7. Then, the third driving member 521 drives the suction nozzle 522 to be away from the positioning column 11, so as to transfer the column; meanwhile, the first driving member 511 drives the second driving member 512 and the lifting bar 513 to descend, when the second driving member 512 and the lifting bar 513 descend to the original height, the first driving member 511 stops working, and the second driving member 512 starts to drive the lifting bar 513 to be away from the positioning column 11.

Correspondingly, the positioning column 11 carrying the product can be transferred to the leveling position, the gluing position, the pressing position and the discharging position one by one along with the rotating disc.

The implementation principle of the automatic back cover machine of tube-shape packing carton of the embodiment of this application is: the driving motor drives the rotating disc to rotate anticlockwise, and drives the positioning column 11 to convey anticlockwise. When the rotating rotary disk conveys the positioning column 11 to the feeding area, the staff places the closing plate 7 on the positioning column 11 and sleeves the cylinder wall 6 outside the positioning column 11.

Then, the rotating rotary disc conveys the positioning column 11 which has finished feeding to the leveling position. At this time, the leveling driving component 22 drives the leveling disc 21 to approach the upper surface of the cylinder wall 6, so that the lower surface of the leveling disc 21 abuts against the upper surface of the cylinder wall 6, and the limit strips of the cylinder wall 6 completely abut against the closing plate 7.

Then, the rotating disc continues to rotate, and the cylinder wall 6 and the closing plate 7 which are leveled are conveyed to the gluing station. At this time, the glue moving driving member 33 drives the mounting plate 311 to move downward, and drives the positioning plate 312 and the glue applying head 321 to move downward. When the lower surface of the positioning disc 312 abuts against the upper surface of the cylinder wall 6, the positioning disc 312 stops moving downwards; the glue moving driving member 33 continues to drive the mounting plate 312 and the glue head 321 to move downwards, and at this time, the spring is compressed. When the gluing head 321 descends to pass through the through hole 313, the gluing movable driving member 33 stops working, and the gluing rotary driving member 322 drives the gluing head 321 to rotate so as to glue between the closing plate 7 and the cylinder wall 6 in a rotary manner.

Then, the rotating disc continues to rotate, and the cylinder wall 6 and the closing plate 7 which are glued are conveyed to a pressing position for pressing and gluing.

Finally, the rotating disc continues to rotate; during the transport of the column to the blanking station, the suction nozzle assembly 52 is moved laterally to be close to the positioning column 11. When the positioning post 11 reaches the lowering position, the lift assembly 51 moves laterally to close the positioning post 11. Then, the lifting assembly 51 moves vertically to lift the lower surface of the cylinder wall 6, and continues to move vertically to drive the cylinder to lift the cylinder to abut against the nozzle assembly 52. The nozzle assembly 52 sucks the column to move the column laterally, and the lift assembly 51 moves downward and then moves laterally away from the positioning post 11.

In the process, before gluing the cylinder wall 6 and the closing plate 7, leveling operation is carried out; the condition that the cylinder wall 6 and the closing plate 7 are incompletely glued due to the fact that the gluing mechanism 3 directly glues the space between the cylinder wall 6 and the closing plate 7 is avoided, the quality of the cylinder column is guaranteed, the manufacturing yield of the cylinder column is improved, and the cost is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
