It will be appreciated that in the production of packaging containers there are typically 2 ways to increase the volume of the final finished packaging container. 1. To increase the height of the package, the corresponding production equipment, the jaw chain of the filling machine must be redesigned and modified to a non-standard format, and the procedure is very complicated and expensive. 2. The width of the packing material is increased, so that the forming part of the pipe needs to be designed and modified, namely the section size of the pipe formed by the sheet material correspondingly needs to be modified, and the structural style and the size of the forming roller in the filling machine need to be modified correspondingly, so that the whole process is relatively easy and cost-effective.

For convenience of description, a 65ml classical triangular bag is taken as an example, and the parameters of the 65ml classical triangular bag in all aspects are as follows, wherein the packaging volume is 65ml, the gross weight of a packaging material is 69g, the width of the packaging material is 129mm, and the diameter of a tube in the package is 38 mm. Based on the current packaging volume and the target packaging volume, the amount of packaging material usage reduction is calculated in comparison in the packaging TS (transverse) direction.

1. Increase the height of the package

For standard external dimension pyramid type package, the height of base is maintained at 105mm, and when the height in TS (transverse direction) is 60mm, the package volume is 63mm ³ (ii) a A package volume of 65.12mm when the height in the TS (transverse) direction is 61mm ³ . The package volume is increased by increasing the package height, and the package volume is 78.56mm when the height of the base is kept unchanged at 105mm and the height in the TS (transverse direction) direction is increased to 67mm ³ (ii) a The package volume was 80.92mm when the height in the TS (transverse) direction increased to 68mm ³ . It can be seen that by increasing the height of the package, the package can be madeThe classical triangular package of 65ml is changed into the classical triangular package of 80ml, but the corresponding procedures are very complicated and expensive.

2. Increasing the width of the packaging material

For the pyramid-shaped package with the standard external dimension, the packaging material is a rectangular plane (corresponding to a sheet material) before forming, the width of the packaging material is 129mm, the internal volume of the internal package after folding and forming is limited, and after the width of the packaging material is increased from 129mm to 142mm, the volume of the packaging container can be effectively increased on the basis of not changing the basic shape of the formed package, and meanwhile, the diameter of the tube material inside the package needs to be correspondingly increased.

Due to the ease of the process and cost considerations, the jaw chain of the filling machine needs to be redesigned and modified to a non-standard format, which is very complicated and expensive, relative to the implementation of solution 1. The method 2 is adopted for development and design, the width of the packaging material is increased, the corresponding tube diameter is increased, the process is easier to realize, and the corresponding finished packaging container can reach the target volume at lower cost. And over time, the associated kits for producing the packages are also developed and manufactured quickly, with fewer redesign modifications required in subsequent processes.

It is known that the cross-sectional dimension of the almost straight cylinder after the sheet material is formed directly affects the volume of the final packaging container, and the structural style and dimension of each structural component in the corresponding forming roller determine the cross-sectional dimension of the straight cylinder after the forming. Therefore, when a packaging container having a target volume is to be produced, each structural component in the forming roll needs to be specifically designed.

Taking the target volume of the packaging container to be manufactured as 80ml, the diameter of the straight tube-shaped material formed by the forming roller in the present application should be 43+/-1mm, and the cross-sectional area should be 1452mm ² Width of the corresponding sheet material142+/-1mm, and has an overlapping portion of 6+/-1mm when formed in a straight tube shape, and a sectional circumference of 136 mm.

Based on this, in a specific embodiment, the dimensions of the structural components in the first one of the forming rolls 10 are in turn as follows:

as shown in fig. 6, the reference sizes a1-j1 of the first roller 13 are: 38.39, 20, 12, 1.7, 26, 9.8, 5.3, 1.7, 20, 43; α 1 and β 1 are: 11.34, 37.87.

As shown in fig. 9, the reference sizes a2-i1 of the second roller 14 are: 37.5, 20, 12, 0.87, 1.7, 26, 1.7, 31.5, 38.39.

As shown in fig. 16, the marked sizes a3-g3 of the second roller 14 are: 45. 42, 20, 12, 2, 24, 47; the radius R corresponding to the arc chamfer at the edge of the second roller 14 is 0.5.

Accordingly, the body portion 121 of the first roller 12 has a cross-sectional diameter of 8 and a length of 35. Similarly, the second roller 22 has a structural size.

As shown in fig. 2, the diameter D1 of the partial arc corresponding to the partial first material passage formed by the outer side surface of the first roller 13 is 52.5, and the perimeter L1 of the cross-sectional edge of the first material passage is 143.5.

As shown in fig. 11, the cross-sectional diameter D2 of the second material passage formed by the outer side surface of the third roller 23 is 44, and the cross-sectional circumference L2 is 138.23.

It will be appreciated that in other embodiments the structural dimensions of the structural components in the respective forming roll may also be any other reasonable set of dimensions corresponding to each other if the packaging container intended to be produced is of other target volume. That is, this application is through adjusting the size of each structural component of first forming roller 10, and then can adjust the cross sectional dimension of first material passageway, just also can satisfy the demand of various capacity specifications of final off-the-shelf packaging container effectively, and the structural style of this forming roller is also comparatively simple to it is also more convenient in making and follow-up maintenance change this forming roller.

In another aspect, the present application further includes a packaging container production apparatus, please continue to refer to fig. 17, and fig. 17 is a schematic structural diagram of an embodiment of the packaging container production apparatus of the present application.

Specifically, the packaging container production equipment sequentially tensions a coiled packaging material into a continuous sheet material with equal width through a plurality of conveying rollers 1, and sequentially conveys the coiled packaging material to a first material passage of a first forming roller 10 and a second material passage of a second forming roller 20 of a forming roller 2 to form a straight tube shape, and then further conveys the coiled packaging material to a packaging container forming device 3 to form a set packaging container style, such as brick packaging, pillow packaging, roof packaging, triangular packaging, and the like, through the packaging container forming device 3.

Wherein, taking the 80ml packaging container as an example, the corresponding manufacturing process is as follows: the packaging material was cut by hand to a width of 142 mm.

The packaging material is fed to a filling machine (packaging container production plant) and, if the quantity of packaging material is sufficient, some filling tests can be tried.

For example, a larger format web of packaging material is cut into a number of 142mm wide webs of packaging material for use in filling water testing on a production line. Cheese products from normal product lines can also be tested in one filling run.

Wherein the packaging material is tested to contain 80g of water or 85g of cheese and is sealed in the ridge line of the packaging material in the transverse direction (TS); -providing a Longitudinal (LS) seal in the overlapping area of the packaging material; the correct position of the strip Seal (SA) is confirmed, and if the seal is not formed, the proper adjustment is needed.
