Unpacking mechanism and packing device

Abstract

The invention discloses a box opening mechanism and a packaging device for the same. The box opening mechanism comprises a fixing face plate, a swing arm, a swing rod, a swing rod drive device, a mounting rod and a steering rod. The swing rod drive device is connected with the swing rod and drives the same to swing and further drives the mounting rod, a roller, a sucker mounting plate and the like to move, and the swing arm which is connected with the swing rod is driven by the swing rod drive device through the swing rod. The roller, the sucker mounting plate and the like are fixed on the mounting rod. Since the steering rod, the mounting rod, the sucker mounting plate and the like are all fixed together, a direction of a sucker on the sucker mounting plate is still consistent with an axial direction of the steering rod, and the roller rolls along a cam slot. When an axis of the steering rod and a central line of a linear slot coincide, the sucker sucks a packaging box. The swing rod drive device moves to drive the swing arm to return along the original way with the roller and drive a pressing plate to press the packaging box to unfold the packaging box. When the axis of the steering rod is opposite to the sucker and a packaging box conveying mechanism, the unfolded packaging box is placed in the packaging box conveying mechanism by the sucker so as to be opened completely.

Description

technical field [0001] The invention relates to the field of packaging equipment, in particular to a box opening mechanism and a box loading device. Background technique [0002] At present, in the packaging of liquid milk, it is usually necessary to pack a plurality of milk packages that have been packaged once into a carton for secondary packaging, so as to facilitate the transportation and sales of the product. [0003] Generally, manual boxing is used, which is inefficient and not suitable for large-scale modern production. There are also manufacturers who use cartoning machines to complete the unpacking and packing actions. When in use, the carton must be opened first before the next step can be performed. At present, after the cartons used for milk packaging come out of the carton factory, in order to save space and facilitate transportation, the cartons are generally folded and the bottom leaves are glued in advance. And if you want to use a packaging carton, you m...

Problems solved by technology

And if you want to use a packaging carton, you must open the folded carton; but because the milk pack is heavier and larger, this kind of carton is relatively large and the cardboard is thicker, and the force required to open the carton is greater. Most of the existing box opening mechanisms are used in the production of small box packaging, and cannot be used well in milk packaging
