Unpacking positioning mechanism of full-automatic packing machine

Abstract

The invention discloses an unpacking positioning mechanism of a full-automatic packing machine, which is used for positioning paper boxes in a folding state before. The unpacking positioning mechanism comprises a rectangular support, a left-right positioning device, an opposite angle positioning device, and a paper box unfolding device, wherein the rectangular support is provided with a base, the left-right positioning device is provided with two first positioning components symmetrically arranged at the left and right sides of the base, the opposite angle positioning device is provided with two second positioning components symmetrically arranged at the front and rear sides of the base, and the paper box unfolding device comprises a first unfolding component connected to the first positioning components and a second unfolding component connected to the second positioning components. According to the unpacking positioning structure provided by the invention, the first positioning components of the left-right positioning device are used for positioning and unfolding the left and right sides of a folded paper box, the two second positioning components of the opposite angle positioning device enable an included angle between any two adjacent sides of the paper box to be a right angle, and thus the section of the unpacked paper box is rectangular or square.

Description

Technical field [0001] The invention relates to the field of packaging machinery, in particular to a box opening positioning mechanism of a fully automatic box filling machine. Background technique [0002] At present, people have produced a nylon distribution box that can be recycled and reused, is safe and non-toxic, and can ship strip or box-shaped items. Because this nylon distribution box is equipped with a scannable identification Electronic barcode, so it is also called electronic distribution box. In order to facilitate transportation and save space, nylon distribution box is folded and pressed into a flat shape before use; when people need to use nylon distribution box to load items, flat nylon The distribution box is expanded into a box shape, and the four cover plates at the back of the nylon distribution box are sealed, and then the nylon distribution box is transported to the loading area through the empty box conveyor, and then the items are placed from the front op...

Problems solved by technology

[0004] However, the support and positioning device mentioned above expands the four sides of the carton at the same time through the cylinder when the box is unpacked. This expansion method needs to strictly control the stroke and operating speed of the cylinders on the four sides, which improves the processing technology requirements for the support and positioning device. It cannot be ensured that the angle between the adjacent sides of the unfolded carton is a right angle
