Abstract

This invention discloses a method for preparing an integrated packaging liner. The method includes the following steps: S1: Waste paper is shredded and soaked using a paper shredder; S2: The soaked waste paper is placed in a solution with an adjusted pH value; S3: The shredded paper with a suitable pH is placed in a heater for high-temperature sterilization; S4: The high-temperature sterilized waste paper is ground into pulp using a rolling mill; S5: The pulp is screened through a sieve, and the resulting pulp residue is again ground into pulp using a rolling mill, and then screened again. This invention, made from waste paper, transforms waste paper into pulp during the integrated packaging liner production process, which is then extruded into shape using hydraulic equipment. This eliminates the need for cutting, assembly, and gluing processes, shortening the production process and reducing manufacturing costs by eliminating scrap material.

Description

Technical Field

[0001] This invention relates to the field of packaging liners, and in particular to a method for preparing an integrated packaging liner. Background Technology

[0002] With the continuous development of the logistics and transportation industry, the requirements for packaging of goods are becoming increasingly stringent. Good packaging can improve the safety and integrity of goods during transportation and prevent damage. When packaging and transporting beverages, beverage bottles are prone to deformation or even breakage under significant external pressure, leading to leakage. Therefore, it is often necessary to place a padding layer inside the packaging box to provide a certain degree of cushioning.

[0003] Most existing packaging liners are made of corrugated cardboard. The production and processing of packaging liners requires cutting, assembly and gluing. After these processes, there will be a lot of excess corrugated cardboard scraps, resulting in high manufacturing costs and many production and processing steps. Therefore, there is a need for an integrated packaging liner preparation method. Summary of the Invention

[0004] The present invention aims to provide a method for preparing an integrated packaging liner. This invention allows users to easily take more items at once, facilitates the placement of the liner into the packaging box, thereby improving packing efficiency and enhancing the liner's support strength.

[0005] The novel technical solution of this invention: an integrated packaging liner, comprising the following steps:

[0006] S1: Shred and soak the waste paper using a paper shredder;

[0007] S2: Place the soaked waste paper into a solution with an adjusted pH value;

[0008] S3: Place the shredded paper with a suitable pH level into the heater for high-temperature steam sterilization.

[0009] S4: Waste paper cooked at high temperature is ground into pulp by a rolling mill.

[0010] S5: The pulp is screened through a sieve, and the resulting pulp residue is put back into the rolling mill to be ground into pulp, and then screened through a sieve again;

[0016] Preferably, the pH value of the solution in step 2 is controlled between 5 and 7.

[0017] Preferably, the time for high-temperature sterilization of shredded paper with appropriate pH in step S3 is controlled between 1 hour and 1.5 hours, and the high-temperature sterilization temperature is controlled above 90°C.

[0018] Preferably, the method for preparing an integrated packaging liner according to claim 1 is characterized in that: the grinding time of the waste paper after high-temperature cooking in step S4 is controlled at 15 minutes.

[0019] Preferably, in step S6, the speed of the centrifuge is controlled between 1400 rpm and 2800 rpm, and the dehydration time is controlled at 30 min.

[0020] Preferably, in step S7, the lime powder is quicklime, and the lime powder is thoroughly mixed with the pulp, heated, evaporated, and dehydrated.

[0028] S2: Place the soaked waste paper into a solution with an adjusted pH value;

[0029] S3: Place the shredded paper with a suitable pH level into the heater for high-temperature cooking and sterilization. Since there are a large number of bacteria on the surface of the waste paper, the bacteria on the surface of the waste paper are removed by high temperature, and the crushing equipment is used to break down the structure of the waste paper.

[0030] S4: Waste paper cooked at high temperature is ground into pulp by a rolling mill, and the rolling mill breaks down the structure of the waste paper.

[0031] S5: The pulp is screened through a screen, and the resulting pulp residue is put back into the rolling mill to be ground into pulp. It is then screened through a screen again to make the pulp even finer.

[0032] S6: The qualified pulp is poured into a centrifuge for initial dewatering to improve the viscosity of the pulp;

[0033] S7: Add lime powder to the pulp after the initial dewatering, stir and mix, heat and evaporate the water to further improve the viscosity of the pulp;

[0034] S8: Pour the dewatered pulp into a hydraulic device and extrude it to form a wet liner, thus preventing the wet liner from collapsing during the drying process;

[0035] S9: Place the damp pad into the drying equipment and dry it at low temperature to obtain a dry pad, so that the damp pad can be fixed and shaped.

[0036] S10: Apply dry adhesive to the surface of the dry liner to further stabilize the structure of the liner, and then dry it at low temperature to obtain an integrated packaging liner.

[0037] In this embodiment, the pH value of the solution in step S2 is controlled at 5-7, and the soaking time is controlled at 1 day to make the waste paper structure loose.

[0038] In this embodiment, the high-temperature cooking sterilization time of the shredded paper with appropriate pH in step S3 is controlled at 1h to 1.5h, and the high-temperature cooking sterilization temperature is controlled at above 90℃, so that the bacteria on the waste paper can be fully removed.

[0041] In this embodiment, the lime powder in step S7 is quicklime, and the lime powder is thoroughly mixed with the pulp, heated and evaporated to reduce the moisture in the pulp and further improve the viscosity of the pulp.

[0042] In this embodiment, in step S8, the pulp is dewatered three times by hydraulic equipment, and the pulp can be squeezed and dewatered by hydraulic equipment to form a shape.

[0043] In this embodiment, the temperature of the low-temperature drying in steps S9 and S10 is controlled between 40°C and 60°C, so that the damp pad can be dried.

[0044] Example 1, such as Figure 1 As shown, waste paper is processed into pulp through the combination of crushing equipment, rolling equipment and screen. Then, the pulp is dewatered and shaped by centrifugation equipment, lime powder and hydraulic equipment. Finally, the structure of the integrated packaging liner is stabilized by the combination of drying equipment and dry glue to prevent damage during use.
