Embodiment 1

[0045] A strong shaping process for a disposable paper container. In this embodiment, the paper container is a round paper plate, which includes the following steps:

[0046] 1) Reference Figure 2a As shown, cut the cardboard and press out the creasing line 4, so that the outline of the bottom 1, slope surface 2 and end edge 3 of the round paper plate can be formed. When cutting the cardboard, first cut out the excess part Form a circular structure in a flattened state of the round paper tray, and cut out four cutting lines 5 along its circumference towards the center point, and the four cutting lines 5 are evenly distributed on the slope surface 2 and the end edge 3 of the round paper tray, Four cutting lines 5 are set so that the structure of the shaped circular paper plate is stable, and the forming effect of the slope surface 2 is good, and the forming is simple. The indentation line 4 includes a first indentation line 41 between the bottom 1 and the slope surface 2 and ...

Embodiment 2

[0050] A strong shaping process for a disposable paper container. In this embodiment, the paper container is a square paper tray, which includes the following steps:

[0051] 1) Reference Figure 3a As shown, cut the cardboard and press out the creasing line 4, so that the outline of the bottom 1, slope surface 2 and end edge 3 of the square paper plate can be formed. When cutting the cardboard, first cut out the excess part Form a square structure in the flattened state of the square paper tray, and cut out four cutting lines 5 along the diagonal direction of the square structure, and the four cutting lines 5 are evenly distributed on the slope surface 2 and the end edge 3 of the square paper tray. The cutting line 5 has an oblique special-shaped structure, and four cutting lines 5 are set to make the shaped square paper plate structure stable, and the forming effect of the slope surface 2 is good, and the forming is simple. The creasing line 4 includes the bottom 1 and the s...

Embodiment 3

[0055] A strong shaping process for a disposable paper container. In this embodiment, the paper container is an oval paper tray, which includes the following steps:

[0056] 1) Reference Figure 4a As shown, the cardboard is cut and the creasing line 4 is pressed out, so that the slope surface 2 and the outline of the end edge 3 of the oval paper plate can be formed. When cutting the cardboard, the excess part is first cut out to form an ellipse The elliptical structure in the flattened state of the oval paper tray, and four cutting lines 5 are cut along its periphery towards the center point, and the four cutting lines 5 are evenly distributed on the slope surface 2 and the end edge 3 of the oval paper tray, Setting four cutting lines 5 makes the structure of the shaped oval paper tray more stable, and the forming effect of the slope surface 2 is good, and the forming is simple, and the indentation line 4 includes the first indentation line 41 between the bottom 1 and the slo...

Abstract

The invention relates to the field of paper containers, in particular to a powerful shaping process for a disposable paper container. The powerful shaping process comprises the following steps of (1) cutting a paperboard and pressing an indentation line so as to form the bottom, the slope surface and the wheel gallery of the end edge of the paper container; ((2) pre-forming the product manufactured in the step (1) to a required height, so that forming the bottom and the slope surface of the paper container; and (3) pressing strong indentation lines and / or elegant curves on the bottom and / or the slope surface and / or the end edge of the product manufactured in the step (2), and performing horizontal shaping, so that shaping the end edge of the paper container, and the problem of fiber recovering after paperboard forming is solved.

Description

technical field [0001] The invention relates to the field of paper containers, in particular to a strong shaping process for disposable paper containers. Background technique [0002] Paper containers (such as paper trays, paper plates) are easy to use and can be used to hold western dishes, bread, cakes, snacks, etc. Compared with ceramic containers, paper containers have the advantages of light weight, low cost, portability, and safety, while corresponding plastic containers have the advantages of high temperature resistance and no pollution, so paper containers are widely used. [0003] The traditional paper container, its general structure is as follows figure 1 As shown, it includes the bottom and the slope surface 2' extending outward and upward from the periphery of the bottom 1'. A container with an opening upward and a certain volume is formed by the bottom 1' and the slope surface 2'. In order to make the formed container have For better structural stability, the...
