Flanging opening and closing device of case unpacker

Abstract

The invention discloses a flanging opening and closing device of a case unpacker. The flanging opening and closing device is characterized in that a power device, a cylinder with a vacuum suction disk, and a return-preventing baffle plate are arranged on a stand body, two guide rail floating rod turning mechanisms are arranged on the same power device, are connected with pusher dogs, and are electrically connected with the return-preventing baffle plate. The flanging opening and closing device has the characteristics of reasonable structure, simple action, convenience in operation, good benefit, low cost, convenience in control, reliability and stability, and the like. Particularly, due to adoption of a mode of simultaneously using a sucker and the pusher dogs, the straight line movement direction is changed by using the guide rail floating rod turning mechanisms, so that two small flangings can be simultaneously unfolded under the condition of one power output, the effects of stability, reliability, large-openness unfolding and the like are realized; and the flange opening and closing device has the advantages of small size, simple structure, and flanging unfolding in place. The flanging opening and closing device fundamentally solves the difficulty in opening the flangings of a case, especially the small flanging, and is an ideal special matching device for opening or closing the flanging of various cases such as cartons and corrugated containers.

Description

technical field [0001] The present invention relates to the opening and closing technology of packing box folding in the box unpacking machine, and more specifically relates to a series of actions such as controlling the folding and opening of cartons and packing boxes during the automatic box opening process of the box unpacking machine Flange opening and closing device for case unpacking machine. Background technique [0002] As we all know, in logistics sorting, the opening of the folds of existing cartons, corrugated boxes and other packaging boxes mainly depends on manual or mechanical operations. In the unpacking operation of tobacco logistics and distribution cigarettes, the large and small folds must be opened in the order of first large and then small. In the traditional box unpacking machine, when the flaps on both sides are opened, it is mainly completed manually, or the flaps are sucked by a suction cup, and the swing cylinder rotates to pull the flaps. However...

AI Technical Summary

Problems solved by technology

However, due to the inconsistent specifications of the cartons, the rotating shaft of the swing cylinder cannot be consistent with the unfolding shaft of the folding, and the folding cannot be opened in time. Moreover, due to the large range of movement of the swing cylinder, the pipelines it leads are easily damaged, and the life of the equipment is short. High cost and poor stability cannot meet the use and safety requirements of the current box-opening machine
