Description

A reusable electrically heated moldable anti-shock and anti-extrusion packaging

technical field

The invention belongs to the technical field of protective packaging, in particular to a reusable electrically heated plastic anti-shock and anti-extrusion packaging.

Background technique

Existing packaging uses various plastic foams, inflatable columns, cartons, pearl cotton, etc., which have the defects of poor reusability and poor shape controllability. After being made into a certain shape, they cannot be used on objects of other shapes, resulting in Waste and pollution, or the strength is not high enough to meet the requirements of anti-extrusion during the transportation of items.

Contents of the invention

The technical problem to be solved by the present invention is to provide a reusable electrically heated plastic anti-shock and anti-extrusion packaging to solve the problems of low reutilization rate of product outer packaging, easy waste and environmental pollution.

The technical solution adopted by the present invention to solve the technical problem is to provide a reusable electrically heated plastic anti-shock and anti-extrusion package, which includes a thermoplastic main part, which is in the shape of a rectangular sheet, and the inside of the thermoplastic main part is The heating wire of the heating device is evenly laid, and the plug interface of the heating device is connected to the port of the heating wire. The plug interface of the heating device is installed on the outer surface of the thermoplastic main part and communicated with the external power supply. The thermoplastic main part is made of thermoplastic resin material .

The thickness of the thermoplastic main part is 1-50 cm.

The softening temperature of the thermoplastic main body is 40-80 degrees.

The thermoplastic main part is folded into a tubular structure with a rectangular cross-section after softening, or a tubular structure with a triangular cross-section, or adjusted to other required shapes or wrapped on the object to be protected, because of its weight. It can be formed into any shape, just like a casting mold. After cooling for a period of time, it will form a transport package that is consistent with the shape and size of the item to be protected. It also limits the space for the packaged item to resist shock and extrusion.

Based on the plasticity of the thermoplastic main part, in order to increase the compression resistance, the present invention can be molded and built into a shape with appropriate size and mechanical stability according to the shape of the article to be protected.

Thermoplastic main part can choose thermoplastic resin according to different anti-shock and anti-extrusion requirements.

After transportation, the present invention is heated again to make it soften and plastic in shape, so that it can be reused.

Beneficial effect

Advantage of the present invention is as follows:

(1) When heating with an electric heating wire heating device, the thermoplastic main part is softened by heating to 40-80 degrees and the shape is plastic, and the present invention is adjusted to the required shape or coated on the object to be protected, because of its weight. Arbitrary shape, just like a casting mold, after cooling for a period of time, it will form a transport package that the user wants to achieve and conforms to the shape and size of the item to be protected.

(2) Based on the plasticity of the thermoplastic main part, in order to increase the compression resistance, the transportation package of the present invention can be molded into a mechanically stable shape of appropriate size, such as a triangle, according to the shape of the article to be protected.

(3) After the thermoplastic main part is heated, softened and cooled, it forms a transportation packaging material with certain elasticity and hardness that can withstand shock and external force extrusion during transportation.

(4) After the transportation, the present invention is heated again to soften and make the shape plastic, so that it can be reused, improve the utilization rate of packaging materials, and alleviate the pollution problem caused by the discarded packaging materials.

detailed description

Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

Example 1

As shown in FIG. 1 and FIG. 2 , a reusable electrically heated plastic anti-shock and anti-extrusion package includes a thermoplastic main body 1 , a heating device plug interface 3 and a heating device heating wire 4 . During use, first turn on the power supply, and the heating device heating wire 4 heats the thermoplastic main body part 1 to make it softened by heat, and the present invention is adjusted to the required shape or coated on the object 2 to be protected, because of its weight, it is pressed into any shape. The shape is like a casting mold, such as the triangle shown in Figure 1, the square shown in Figure 2, or any other shape. After cooling for a period of time, the anti-shock and anti-extrusion shape that the user wants to achieve is consistent with the shape and size of the object 2 to be protected. transport package. After use, turn on the power again, the heating device heats the thermoplastic main body part 1 to make it softened by heat, and the package of the present invention is removed for next use.

The thermoplastic body part 1 adopts polystyrene.

Polystyrene (PS) has the characteristics of low price, good molding performance, and high rigidity. The continuous use temperature of ordinary polystyrene is 60-80°, and it begins to become a melt at 120°. After 180°, it has fluidity and heat stability. Good performance, more than 300 ° began to decompose.

Adding synthetic rubber to styrene monomer, HIPS can be prepared by free radical polymerization, such as copolymerizing styrene and polybutadiene, a polystyrene with excellent impact strength can be obtained.

The molding technology of polyethylene and polypropylene plastics is used to control the impact strength, the rubber component is added to improve the toughness, and the chlorinated paraffin component is added to reduce its melting point.

Fig. 4 is a preferred circuit of the heating wire in the heating device of the present invention, which is not limited to this layout.

Fig. 5 is a schematic diagram of the assembly structure of Embodiment 1 of the present invention. Because the shape of the packaging of the present invention can be adjusted arbitrarily, different shapes can be combined according to needs, so as to fully utilize the space and improve the use strength.
