Folding package piece bottom end plate folding method

Abstract

The invention relates to a folding package piece bottom end plate folding method, which uses a ring hinge formed by hinging a plurality of station chain links and comprises the following steps: A, feeding a package piece with end folding plates from a supply platform, and allowing the end folding plates to enter clearances between adjacent station chain links; B, rotating the ring hinge to allow the blade of a following station chain link to push the package piece to move toward a top branch, so that the end folding plates are withdrawn by a front station chain link from the clearances and folded backward onto the end part; C, allowing a guide part above a C-shaped part at the supply platform to press the end part of the package piece to make the end part of the package piece flat; and D, allowing the rear end face of a rear supporting part to guide the end folding plates (14) to fold the end folding plates (14) onto the end part (9). The package piece is fed from the supply platform; while the station chain link linearly moves towards a top branch with the C-shaped part, the blade of the rear chain link pushes to package piece to move close to the blade of the front chain link, and the rear end face of the rear supporting part allows the end folding parts to fold backward onto the end part. The method simplifies folding and has a good folding effect.

Description

technical field [0001] The present invention relates to a method of folding a package, and more particularly to a method of folding a bottom end flap of a package. Background technique [0002] At present, many fillable foods such as milk, beverages, fruit juices, etc. are filled in packages made of sterilized packaging materials on the market for sale. A typical example of such a package is a parallelepiped-shaped package produced by folding and sealing laminated strip-shaped packaging materials. A packaging material having a multi-layer structure comprising a layer of a fibrous material, such as paper; both layers covered with a thermoplastic material, such as polyethylene; and a barrier layer on the side of the packaging material that ultimately comes into contact with food , such as aluminum foil; and applying one or more layers of heat-sealable plastic material to the barrier layer, which ultimately forms the inner surface of the package that comes into contact with th...

Problems solved by technology

This folding unit belongs to a chain conveyor mechanism, the impact surface of the folding mechanism performs the folding of the end flaps onto the end parts during the transport of the package from the infeed station to the output station, However, the mechanism for setting the folding mechanism on the conveying part is complex, and the end flap is folded forward onto the end portion, and the folded end flap will It is easy to be turned up by the action of the folding device and affect the subsequent operation, thus affecting the forming effect of the package
