[0018] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following will be further detailed to the utility model in combination with specific embodiment.

[0019] AsFigure 1 , Figure 2 and Figure 3 As shown, a portable foam cushioning bag includes a plastic bag body 1. A first bag body 2 and a second bag body 3 are fixedly installed on both sides of the inner wall of the plastic bag body 1. The interior of the first bag body 2 is filled with isocyanate, and the interior of the second bag body 3 is filled with polyether. A protruding area 9 is opened at one end of the first bag body 2 and the second bag body 3, and two sets of arc-shaped areas 10 are provided at the other end of the first bag body 2 and the second bag body 3. A first rod body 5 and a second rod body 6 are respectively attached to the outer sides of the plastic bag body 1. Both ends of the first rod body 5 and the second rod body 6 are fitted with clip strips 8.

[0020] In this embodiment, when a foamed cushioning bag is needed, the plastic bag 1 is laid flat, and the first bag 2 and the second bag 3 are crushed. This allows the materials inside the first bag 2 and the second bag 3 to be dispersed through the convex area 9 at the top and the arc area 10 at the bottom, maximizing their distribution within the plastic bag 1. This allows the combined polyether and isocyanate inside the first bag 2 and the second bag 3 to leak out. Then, the first rod 5 and the second rod 6 are moved on both sides of the outside of the plastic bag 1 to evenly spread the combined polyether and isocyanate materials during the reaction, forming a foam structure that expands within the plastic bag 1, thereby covering different product shapes. The convex area 9 and the two sets of arc areas 10 facilitate the outward dispersion of the materials inside the first bag 2 and the second bag 3 when squeezed out, preventing gaps at the corners of the plastic bag 1. At the same time, the first rod 5 and the second rod 6 can be used to roll up the plastic bag 1 for easy carrying.

[0021] As one implementation method, such as Figure 2 and Figure 3 As shown, both the first bag 2 and the second bag 3 are inflatable bags, and the dimensions of the first bag 2 are the same as those of the second bag 3.

[0022] In this embodiment, the first bag 2 and the second bag 3 are then crushed, causing the materials inside the first bag 2 and the second bag 3 to be dispersed through the top convex area 9 and the bottom arc area 10, so that they can be distributed to the plastic bag 1 to the greatest extent, causing the combined polyether and isocyanate inside the first bag 2 and the second bag 3 to leak out.

[0023] As one implementation method, such as Figure 1 As shown, a sealing clip 4 is provided at the opening of the plastic bag 1.

[0024] In this embodiment, when the polyether reacts with the isocyanate to generate polyurethane resin, a foam structure is formed and expanded inside the plastic bag 1. The opening is then sealed with a sealing clip 4 to prevent the material from leaking out and causing environmental pollution.

[0025] As one implementation method, such asFigure 2 As shown in the drawings, the first rod 5 and the second rod 6 include a thin rod 11 and a thick rod 12, one end of the thin rod 11 is sleeved with one end of the thick rod 12.

[0026] In this embodiment, the first rod 5 and the second rod 6 are placed outside the plastic bag 1 in advance, and the two ends are sleeved with the clamping strip 8, and the connection of the thin rod 11 and the thick rod 12 is suitable for different sizes of the foaming buffer bag.

[0027] As an embodiment, as shown in Figure 1 , Figure 2 As shown in the drawings, the clamping strip 8 is a rubber material member, and the clamping strip 8 is in an annular structure, and the clamping strip 8 is in interference fit with the first rod 5 and the second rod 6.

[0028] In this embodiment, the extendability of the clamping strip 8 is used, and the clamping strip 8 is sleeved outside the first rod 5 and the second rod 6, the distance between the first rod 5 and the second rod 6 is limited, so that the plastic bag 1 can be moved outside the plastic bag 1, the combination of polyether and isocyanate material in the reaction of the plastic bag 1 is uniformly spread, the foaming rate is fast, and the influence of uneven foaming on the wrapping of the product is avoided.

[0029] As an embodiment, as shown in Figure 1 As shown in the drawings, one side of the plastic bag 1 is provided with a pressing mark 7 corresponding to the first bag 2 and the second bag 3.

[0030] In this embodiment, through the pressing mark 7 outside the plastic bag 1, the positions of the first bag 2 and the second bag 3 can be directly understood, when the foaming buffer bag is needed, the first bag 2 and the second bag 3 are pressed and broken by external pressure, so that the combination of polyether and isocyanate in the first bag 2 and the second bag 3 reacts to generate polyurethane resin, and then forms foam expansion in the plastic bag 1.

[0031] Working principle: in use, the first rod body 5 and the second rod body 6 are placed outside the plastic bag 1 in advance, and the two ends are sleeved with the sleeve clamping strip 8, when the foaming buffer bag is needed, the plastic bag 1 is placed horizontally, the pressing mark 7 outside the plastic bag 1 is pressed by external pressure, then the first bag body 2 and the second bag body 3 are broken, the materials in the first bag body 2 and the second bag body 3 are dispersed through the top notch area 9 and the bottom arc notch area 10, and can be distributed to the plastic bag 1 to the maximum extent, so that the combined polyether and isocyanate in the first bag body 2 and the second bag body 3 are leaked; then the first rod body 5 and the second rod body 6 are moved on the outside of the plastic bag 1 on both sides, and the combined polyether and isocyanate materials in the reaction are uniformly spread, after spreading, the plastic bag 1 is randomly folded into the required shape, the combined polyether and isocyanate are reacted to generate polyurethane resin, and gradually form a foaming structure in the plastic bag 1, and then the different product shapes are coated, finally the sealing clamp 4 is used to seal the opening, so as to avoid the material from flowing out and polluting the environment.
