Box sucking and opening mechanism for packaging box

Abstract

The invention discloses a box sucking and opening mechanism for a packaging box. The mechanism is mainly characterized in that first rotating shafts are arranged on a rotating disc at equal intervals,the first rotating shafts are provided with second rotating shafts correspondingly, the second rotating shafts are movably connected with rocker arms correspondingly, third rotating shafts are installed on the rocker arms correspondingly, the second rotating shafts and the third rotating shafts are sleeved with sleeves correspondingly, synchronizing wheels on the second rotating shafts can rotatewhile revolving around a large synchronizing wheel, synchronizing wheels on the second sleeves can rotate while revolving around the synchronizing wheels on the second rotating shafts correspondingly, synchronizing wheels on the third rotating shafts can rotate while revolving around the synchronizing wheels on the second sleeves correspondingly, and suction nozzles and swing rods are arranged onmounting frames on the third rotating shafts correspondingly. According to the mechanism, the flat paper box placed in a box storage frame can be sucked and rotated and then sucked by another suctionnozzle to be opened, finally, through swinging of the swing rods, the opened packaging box is straightened and falls onto a conveying belt, objects can be conveniently pushed into the packaging box to be packaged, and the mechanism has the characteristics of being scientific in structure and stable in work.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a mechanism for sucking and unpacking a packaging box. Background technique [0002] In the common cartoning machine, the box opening part is that the box opening suction cup directly sucks down the folded carton in the box storage frame, and then stretches the carton open. It is easy to make mistakes in the action of the suction paper box. For example, if the paper box is not sucked down, it will cause subsequent misoperation, resulting in downtime and waste of raw materials. In order to solve this problem, the utility model patent whose authorized announcement number is CN203727745U and named "a new type of box packing machine suction box for medicine board packaging box" discloses the following content: a new type of medicine board packaging box. The machine suction box is characterized in that: the suction box includes a rotary arm press block, a spring sheet carton pressure plate, an ...

AI Technical Summary

Problems solved by technology

The suction box device of this structure uses a turntable to rotate the suction box, and the storage device must have a slope that matches the suction cup, otherwise, the suction cup cannot absorb the packaging box, and the storage device with this slope only needs to have a slope to match the suction cup. Subsequent packaging boxes can be put in manually, which cannot be done in an automated production line

And this kind of suction box device, after its packing box is sucked, still need to use other box opening mechanism to open packing box, put on the conveyer belt after opening, also not the inner cavity of founder
