[0002] An automatic packaging production line is an automated line body that packages items according to set packaging requirements and processes, using the packaged items and packaging boxes. In the prior art, there is a type of packaging box for an automatic packaging line called a sheet box, which is equivalent to a sheet of packaging box material that has been printed and die-cut but not yet glued and formed. Its main processes on the automatic packaging line include folding and forming the packaging box, loading items into the box, and sealing the box.

[0003] As Figure 1 shown is a common type of packaging sheet box in the prior art. Its use process on the automatic packaging line is mainly to transport the sheet box to the automatic gluing station for gluing the bonding part, then transport it to the loading station for item stacking, and then use the automatic folding mechanism of the packaging line to fold and form the side parts of the sheet box. However, this packaging sheet box still has the following problems:

[0004] This type of sheet box needs to be glued on the packaging line, and on-line gluing will increase the costs of the production enterprise of the packaged items. At the same time, the side sheets and side sealing overlapping sheets of this type of sheet box are rectangular in design, and generally the die-cut openings between them are relatively small, which is likely to cause movement interference between adjacent box sheets during the folding and forming by the automatic folding mechanism, resulting in folding disorder or forming failure.

[0005] Based on this, the utility model designs an automatic forming sheet box for an automatic packaging line to solve the above problems. Content of the Utility Model

[0008] An automatic forming sheet box for an automatic packaging line, comprising a box sheet,

[0009] Folding score lines are provided on the side walls of the box sheet. The box sheet is divided into a top sheet, a rear sheet, a bottom sheet, a front sheet, side sheets, side sealing overlapping sheets, and a top sealing overlapping sheet through the folding score lines. The rear sheet is fixedly connected to the lower end of the top sheet; the bottom sheet is fixedly connected to the lower end of the rear sheet; the front sheet is fixedly connected to the lower end of the bottom sheet; side sheets are symmetrically and fixedly connected to the left and right sides of the top sheet and the bottom sheet, and the side sheets are trapezoidal; side sealing overlapping sheets are symmetrically and fixedly connected to the left and right sides of the rear sheet and the front sheet; a top sealing overlapping sheet is fixedly connected to the lower side of the front sheet;

[0010] A gluing mechanism is provided on the front side of the box sheet.

[0011] Further, the adhesive mechanism includes an adhesive layer and a release paper strip. Adhesive layers are provided on the front sides of the side sealing tabs and the top sealing tabs, and corresponding release paper strips cover the front sides of the adhesive layers.

[0012] Further, ventilation holes are provided on the side walls of the rear sheet and the front sheet.

[0013] Further, a release paper strip remaining section is fixedly connected to the end of the release paper strip.

[0014] Further, the box sheet is made of corrugated cardboard or grey board.

[0015] Further, the thickness of the box sheet is 1.5 - 5 mm.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. Fold and press the box sheet along the folding score line, and adhesively bond and form between the top sheet, the rear sheet, the bottom sheet and the front sheet through the adhesive mechanism. The side sheets are trapezoidally designed to prevent folding disorder or forming failure caused by interference between the side sealing tabs and the side sheets when the folding mechanism of the packaging automatic line folds the side sealing tabs.

[0017] 2. The packaging automatic line tears the release paper strip through the release paper strip remaining section, then folds and presses the box sheet into a box body along the folding score line, and fixes and forms the box sheet through the adhesive layer, without applying glue on the packaging automatic line, reducing costs, and being convenient, fast and improving efficiency.
