Description

Technical Field

[0001] The present application relates to the field of packaging, and in particular to a high-fastness pearl cotton packaging piece and a cutting die thereof. Background Art

[0002] Polyethylene foam is a non-cross-linked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene. It overcomes the shortcomings of ordinary foam rubber, such as fragility, deformation, and poor resilience. It has many advantages such as waterproof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance and is an ideal substitute for traditional packaging materials.

[0003] The packaging in the related art, refer to Figure 1 , comprising a packaging portion 1, wherein the packaging portion 1 is provided with a packaging groove 2, wherein the packaging groove 2 comprises a thin groove 21 for placing a thin plate member, and the thickness of the thin groove 21 is 0.6-1 cm.

[0004] Regarding the above-mentioned technology, the inventor believes that the opening of the thin groove is small, and it is difficult to insert the thin plate parts during packaging. In order to facilitate insertion, the width of the thin groove is usually set to be larger than the thin plate parts, resulting in poor fastening of the thin plate parts after packaging, and they are easy to fall out, making the packaging inconvenient to use. Utility Model Content

[0005] In order to improve the fastness of the packaging to the product, the present application provides a high-fastness pearl cotton packaging and a cutting mold thereof.

[0006] In the first aspect, the present application provides a high-fastness pearl cotton packaging, which adopts the following technical solution:

[0007] A high-fastness pearl cotton packaging piece comprises a packaging part and a packaging groove opened on the top surface of the packaging part, wherein the packaging groove comprises a thin groove for placing a thin plate member, the side wall of the thin groove facing the thin plate member is an arc surface, the arc surface is protruding at the center of the thin groove wall, and the thickness of the thin groove increases toward the groove opening.

[0008] By adopting the above technical solution, an arcuate surface is provided on the inner wall of the thin groove, so that the outer diameter of the thin groove opening is slightly larger than the thin plate part, which is convenient for the thin plate part to be inserted into. The arcuate surface is protrudingly provided at the center of the thin groove wall, so that the thin plate part is clamped by the arcuate surface, thereby improving the fastening.

[0009] Optionally, the thin groove runs through both sides of the packaging portion along its depth direction.

[0010] By adopting the above technical solution, since the fastening of the thin groove to the product is improved, the thin groove is set through, the product is not easy to separate from the packaging part, and the processing of the through groove is more convenient.

[0011] Optionally, the width of the thin groove is 0.6-1 cm.

[0012] Optionally, the height of the most protruding position of the arc-shaped surface is 0.2-0.4 cm.

[0013] By adopting the above technical solution, the arc surface can be pressed against the thin plate member conveniently.

[0014] In a second aspect, the present application provides a cutting die, which adopts the following technical solution:

[0015] A cutting die is used for cutting the thin groove on the above-mentioned packaging part; it comprises a template and a first cutter arranged on one side of the template; the first cutter comprises a rectangular frame, and the distance between the blade of the first cutter and the template is 0.4-0.6 times the depth of the thin groove.

[0016] By using the above technical solution, since the depth of the thin groove is greater than the depth of the cutter, the packaging part is compressed during cutting, and since the notch of the thin groove is small, an arc surface is directly formed on the groove wall of the thin groove after cutting, so that the arc surface does not need additional processing.

[0017] Optionally, the thickness of the rectangular frame blade is 0.2-0.4 mm.

[0018] By adopting the above technical solution, the thickness of the blade is not easy to be too thin. If it is too thin, the compression effect of the packaging part will be cross-shaped and the curved surface will be difficult to form. If it is too thick, burrs will easily appear, affecting the quality of the packaging.

[0019] Optionally, the packaging groove also includes a accommodating groove, the width of the accommodating groove is 1.5-3cm; a second cutter is also provided on the template; a notch is provided in the middle of the length edge of one side of the rectangular frame, the second cutter includes a first blade and a second blade, the end of the first blade is connected to the end of the first cutter close to the notch, and the second blade is connected to the other end of the notch on the first cutter.

[0020] By adopting the above technical solution, it is convenient to form a receiving groove on the packaging piece.

[0021] Optionally, the distance from the blade of the second cutter to the template is the same as the distance from the blade of the first cutter to the template.

[0022] By adopting the above technical solution, since the width of the receiving groove is 1.5-3 cm, the wider groove is difficult to produce an arc surface when cutting in the compressed state of the packaging part, and thus will not affect the formation of the receiving groove.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The inner wall of the thin groove is provided with an arc surface, so that the thin plate is clamped by the arc surface, thereby improving the fastening performance;

[0025] 2. The thin groove runs through both sides of the packaging part along its depth direction, which is convenient for thin groove processing;

[0026] 3. The distance from the blade of the first cutter to the template is 0.4-0.6 times the depth of the thin groove, so that the packaging part is compressed during cutting, and a curved surface is directly formed on the groove wall of the thin groove, so that the curved surface does not need additional processing, making the curved surface processing convenient.
