It is only stated that the terms of orientation such as up, down, left, right, front, back, inner, outer, etc. used in this document or the imminent present invention, are used only with reference to the drawings of the present invention, and are not meant to be limiting in any way.
It should be noted that the liquid in-line printed package of the present invention refers to a package paper for packaging liquid, and the package paper is stacked into a box shape for carrying liquid. The package paper is composed of paper 100 at the outer layer of the liquid package box body and a composite film 200 at the inner layer of the liquid package box body.
Referring to fig. 1, the invention discloses a first embodiment flow chart of a liquid connection line printing packaging production line process method, which comprises the following steps:
S101, unreeling paper.
S102, punching holes on the paper to form a plurality of continuous holes on the paper.
Wherein the continuous holes are arranged on the paper at intervals along a preset track so that the paper can be separated from the composite film through the continuous holes. Specifically, a trace similar to a broken line is shown on the surface of the finished liquid packaging box, and the trace is formed by arranging a plurality of continuous holes at intervals along a preset track. The arrangement of the continuous holes does not influence the normal use of the liquid packaging box and can not leak liquid. After the liquid package is used, a worker can tear the paper away from the composite film gradually along the track of the continuous hole, so that the paper and the composite film are separated and recycled respectively, recycling is possible, and the operation is simple and easy.
S103, gluing the preset position of the paper.
The step is to glue the predetermined position of the paper to bond it with the composite film, and to bond the four corners of the box when the box is subsequently formed.
S104, unreeling the composite film.
S105, gluing the preset surface of the composite film.
The step is to glue the preset position of the composite film so that the composite film can be adhered with paper.
S106, compounding the glued paper with the composite film to form a liquid package.
S107, liquid packaging and rolling.
The process method of the liquid connecting line printing packaging production line combines a plurality of working procedures of the paper and the composite film, only needs one unreeling and reeling operation, has less steps, saves time and labor, reduces the arrangement of machines, ensures that equipment occupies less area and has compact structure, and achieves the purposes of saving cost and improving production efficiency. In addition, the invention adds a punching process to the paper, so that a plurality of continuous holes are formed on the paper and are distributed on the paper at intervals along a preset track. When the paper is recovered, a worker only needs to tear the paper from the composite film gradually along the preset track of the paper from the continuous hole, so that the paper and the composite film can be separated, the operation is easy, and the liquid package can be recovered and reused conveniently.
As shown in fig. 2, the invention also discloses a second embodiment of a process method of the liquid connection line printing packaging production line, which comprises the following steps:
S201, unreeling paper.
S202, punching holes on the paper to form a plurality of continuous holes on the paper.
S203, gluing the preset position of the paper.
S204, unreeling the composite film.
And S205, sizing the preset surface of the composite film.
S206, cutting off the part of the composite film at the sticking part of the side face of the liquid package.
In addition to the upper and lower ends of the liquid packaging box, the sides thereof need to be bonded to form the liquid packaging box body. The side of the box body is overlapped on the other side through one side of the packing paper and then is adhered by glue. Before the paper and the composite film are compounded, the composite film at the position where the side surface of the liquid packaging box needs to be bonded is removed, so that the front surface and the back surface of the paper are bonded, but not the front surface of the paper is bonded with the composite film, and the problems of infirm bonding, poor bonding effect, thicker bonding position, unattractive appearance and the like caused by different materials are avoided.
For example: the printed side of the sheet, i.e. the front side, is transversely provided with four identical patterns representing four liquid packaging sheets, and the invention requires the cutting of the composite film corresponding to the position between the two adjacent liquid packaging sheets. Therefore, three composite membrane strips are cut out on the composite membrane, and the width of the composite membrane strips is the width of the bonding place. Thus, when the side surfaces of the liquid packaging box are bonded, the printing surface, namely the front surface, of the paper can be bonded with the back surface of the paper.
