Description

Technical Field

[0001] This utility model relates to the field of pearl cotton technology, specifically a high-strength pearl cotton. Background Technology

[0002] In the packaging materials industry, EPE foam (polyethylene foam) is widely used due to its lightweight, softness, and shock absorption properties. However, traditional EPE foam has significant shortcomings in practical use. Most existing EPE foams have a single-density structure, which limits their resistance to pressure and impact when subjected to external pressure or impact, making them prone to deformation or even damage. This makes it difficult to provide reliable protection for items requiring high-strength protection, such as precision instruments and electronic products.

[0003] Meanwhile, traditional pearl cotton lacks effective protective measures for its edges. During transportation and storage, the edges are easily worn and scratched. Long-term exposure to complex environments may also cause corrosion. This not only affects the appearance of pearl cotton, but also greatly shortens its service life and increases the cost of use. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a high-strength pearl cotton, which can effectively solve the technical problem that the current pearl cotton cannot resist pressure due to its poor strength.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A high-strength pearl cotton includes a low-density inner layer and two high-density outer layers, wherein the low-density inner layer is sandwiched between the two high-density outer layers to form a composite structure.

[0007] The low-density inner layer is molded on both sides to form multiple honeycomb-shaped grooves, and the grooves on both sides are staggered.

[0008] The high-density outer layer has multiple protrusions on its inner side that match the shape of the groove. The high-density outer layer and the low-density inner layer are fixed by the protrusions being inserted into the corresponding groove.

[0009] The low-density inner layer and the high-density outer layer are connected by a protective layer that wraps around the side. The protective layer has multiple protruding snap-fit ​​ends at both ends of the opening. The snap-fit ​​ends are fixed by being embedded in the pre-set slots of the high-density outer layer.

[0010] Furthermore, the groove body is provided with a raised trapezoidal platform, and the raised part is provided with a trapezoidal groove at the corresponding position to cooperate with the trapezoidal platform.

[0011] Furthermore, the snap-fit ​​end is detachably connected to the protective layer, and one end of the snap-fit ​​end is provided with a mounting part for insertion and fixing inside the protective layer, and the protective layer is provided with a mounting hole that matches the mounting part at the corresponding position.

[0012] Furthermore, the snap-fit ​​end has a hook-shaped structure.

[0013] Furthermore, both sides of the two high-density outer layers that are far apart from each other are coated with a PU coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-4 As shown, this utility model provides a high-strength pearl cotton, which has a composite structure, mainly composed of a low-density inner layer 1, two high-density outer layers 2, a protective layer 3, and related connecting structures. This structural design aims to fully utilize the characteristics of pearl cotton with different densities to improve the overall strength and performance of the pearl cotton.

[0028] The composite structure consists of a low-density inner layer 1 and a high-density outer layer 2. The low-density inner layer 1 is made of pearl cotton material and has a low density. Multiple honeycomb-shaped channels 101 are formed on both sides of the inner layer 1 through a molding process. These channels 101 are evenly distributed, and the channels 101 on both sides are staggered. For example, on one side of the low-density inner layer 1, the channels 101 are arranged at a certain row and column spacing, while on the other side, the arrangement of the channels 101 is offset relative to the first side. This staggered distribution increases the stability and deformation resistance of the structure.

[0029] The high-density outer layer 2 is also made of pearl cotton, but its density is higher than that of the low-density inner layer 1. The high-density outer layer 2 consists of two layers, located on either side of the low-density inner layer 1. Inside the high-density outer layer 2, there are multiple protrusions 201 that match the shape of the groove 101 of the low-density inner layer 1. When the high-density outer layer 2 and the low-density inner layer 1 are assembled, the protrusions 201 of the high-density outer layer 2 can engage with the corresponding groove 101 of the low-density inner layer 1, achieving a fixed connection between the two.

[0030] To further enhance the connection strength between the low-density inner layer 1 and the high-density outer layer 2, a raised trapezoidal platform 102 is provided inside the groove 101, while a trapezoidal groove 203 is provided at the corresponding position of the raised portion 201 of the high-density outer layer 2 to cooperate with the trapezoidal platform 102. When the raised portion 201 is engaged with the groove 101, the trapezoidal platform 102 will be embedded in the trapezoidal groove 203, forming a mortise and tenon structure, further preventing relative sliding and separation between the two and improving the overall structural stability.

[0031] After the low-density inner layer 1 and the high-density outer layer 2 are connected, a protective layer 3 is wrapped around their sides. The protective layer 3 serves to protect the internal composite structure and prevent external objects from damaging the edges of the pearl cotton.

[0032] The protective layer 3 has multiple protruding snap-fit ​​ends 4 at both ends. The snap-fit ​​ends 4 are detachably connected to the protective layer 3. Specifically, one end of the snap-fit ​​end 4 has a mounting part 401 for insertion and fixation into the inner side of the protective layer 3, and the protective layer 3 has a corresponding mounting hole 301 that matches the mounting part 401. During installation, the mounting part 401 of the snap-fit ​​end 4 is inserted into the mounting hole 301 of the protective layer 3 to achieve connection between the snap-fit ​​end 4 and the protective layer 3. The snap-fit ​​end 4 has a hook-shaped structure, which increases the snap-fit ​​strength between the snap-fit ​​end 4 and the high-density outer layer 2.

[0033] The high-density outer layer 2 has a pre-set slot 202. When the protective layer 3 is wrapped around the side, the snap-fit ​​end 4 is embedded into the slot 202 of the high-density outer layer 2. Through the cooperation of the hook-shaped structure with the slot 202, the protective layer 3 and the high-density outer layer 2 are fixedly connected, thereby ensuring the integrity of the entire pearl cotton structure.

[0034] On the sides of the two high-density outer layers 2 that are far apart from each other, a PU coating 5 is sprayed on. The PU coating 5 has good wear resistance, water resistance, and corrosion resistance, which can further improve the performance of the pearl cotton surface and extend its service life. During spraying, professional spraying equipment is used to ensure that the PU coating 5 is evenly covered on the surface of the high-density outer layer 2, forming a dense protective film.

[0035] During manufacturing, according to design requirements, low-density and high-density pearl cotton raw materials, as well as materials for making protective layer 3 and PU coating 5, are prepared. Using molding equipment, honeycomb-shaped grooves 101 are molded onto the low-density pearl cotton, and raised trapezoidal platforms 102 are formed within the grooves 101. Protrusions 201 matching the grooves 101 of the low-density inner layer 1 are machined onto the high-density pearl cotton, and trapezoidal grooves 203 are machined at corresponding positions on the protrusions 201. Two high-density outer layers 2 are placed on either side of the low-density inner layer 1, so that the protrusions 201 of the high-density outer layer 2 engage with the grooves 101 of the low-density inner layer 1, while ensuring that the trapezoidal platforms 102 are embedded in the trapezoidal grooves 203, thus completing the composite assembly of the low-density inner layer 1 and the high-density outer layer 2. The protective layer 3 is wrapped around the side of the composite structure. The mounting part 401 of the snap-fit ​​end 4 is inserted into the mounting hole 301 of the protective layer 3, and then the snap-fit ​​end 4 is embedded into the slot 202 of the high-density outer layer 2 to fix the protective layer 3. Using a spraying device, a PU coating 5 is evenly sprayed on the side of the two high-density outer layers 2 that are far apart from each other. After the coating dries, the manufacturing of the entire high-strength pearl cotton is completed.

[0036] Compared with traditional technologies, the pearl cotton provided by this technical solution has a composite structure of low-density inner layer 1 and high-density outer layer 2, and a honeycomb connection structure is set at the joint. In addition, the protective layer 3 is set, which provides all-round protection for the pearl cotton. This makes the pearl cotton have high pressure resistance and impact resistance, and can effectively withstand external pressure and impact without being easily deformed or damaged. At the same time, it prevents its edges from being damaged by wear, scratches, corrosion and other damage, thus extending its service life.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
