Description

Technical Field

[0001] This utility model relates to the field of plastic steel strapping technology, specifically a PET plastic steel strapping. Background Technology

[0002] PET strapping, also known as plastic strapping or PET packing strap, is a high-density fiber strap made from polyethylene terephthalate (PET) through a fine processing process. It is an internationally recognized environmentally friendly packing strap.

[0003] There is a type of PET plastic steel strapping (CN201820154889.2). When two PET plastic steel strappings are connected, the connection strength between them is increased, thereby extending the service life. However, there are shortcomings. Existing equipment has problems such as insufficient tensile strength, poor wear resistance, and easy loosening after bundling. In the process of transporting heavy building materials and mining equipment parts, the strapping is prone to breakage, causing the goods to scatter. This not only affects the transportation efficiency but also poses a significant safety hazard. Furthermore, the winding stability is poor. Therefore, there is a need for a new type of PET plastic steel strapping to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a PET plastic steel strapping to solve the problems mentioned in the background art, such as insufficient tensile strength, poor wear resistance, and easy loosening after bundling. In the process of transporting heavy building materials and mining equipment parts, the strapping is prone to breakage, causing the goods to scatter, which not only affects the transportation efficiency but also poses a significant safety hazard. In addition, the strapping has poor winding stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PET plastic steel strapping, comprising a strapping body, a PET base material layer fixedly connected to the inner wall of the strapping body, anti-slip teeth fixedly connected to the upper and lower ends of the strapping body, and interlocking grooves provided on both sides of the upper end of the strapping body, and interlocking protrusions fixedly connected to both sides of the lower end of the strapping body, a reinforcing fiber layer wrapped around the outer side of the PET base material layer, and a wear-resistant protective layer wrapped around the outer side of the reinforcing fiber layer, and reinforcing ribs embedded in the inner wall of the PET base material layer.

[0006] Preferably, the packing straps are connected by interlocking protrusions within interlocking grooves in a limiting and snap-fitting manner.

[0007] Preferably, the anti-slip teeth are symmetrically distributed on the outer side of the packing strap body, and the anti-slip teeth are made of leaf vein-shaped anti-slip rubber material.

[0008] Preferably, the wear-resistant protective layer is made of high-density polyethylene, and the wear-resistant protective layer and the reinforcing fiber layer are connected by extrusion molding.

[0009] Preferably, the reinforcing ribs are made of polypropylene, and the reinforcing ribs are distributed in a cross structure on the inner wall of the PET base material layer.

[0010] Preferably, the reinforcing fiber layer is made of woven mesh glass fiber, and the reinforcing fiber layer is bonded to the PET base material layer with hot melt adhesive.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This PET plastic steel strapping can be constructed with a three-layer composite structure consisting of a PET base material layer, a reinforcing fiber layer, and a wear-resistant protective layer. The glass fiber mesh structure of the reinforcing fiber layer can significantly improve the tensile strength of the strapping, while the wear-resistant protective layer can effectively improve the wear resistance of the strapping and extend its service life. In addition, the anti-slip teeth can increase the friction between the strapping and the bundled items, preventing the strapping from loosening. Furthermore, the interlocking protrusions can be inserted into the interlocking grooves for limiting and winding, making it more stable and preventing deviation. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1-5This utility model provides a technical solution: a PET plastic steel strapping, including a strapping body 1, anti-slip teeth 2, a wear-resistant protective layer 3, reinforcing ribs 4, interlocking grooves 5, reinforcing fiber layer 6, PET base material layer 7, and interlocking protrusions 8. The PET base material layer 7 is fixedly connected to the inner wall of the strapping body 1. The strapping bodies 1 are connected by interlocking protrusions 8 within the interlocking grooves 5 in a limiting and coiled manner, thus allowing the strapping bodies 1 to be collected and prevented from shifting. Anti-slip teeth 2 are fixedly connected to the upper and lower ends of the strapping body 1, and interlocking grooves 5 are provided on both sides of the upper end of the strapping body 1. The anti-slip teeth 2 are symmetrically distributed on the outer side of the strapping body 1, and are made of leaf vein-shaped anti-slip rubber material, allowing for double-sided anti-slip treatment. Interlocking protrusions 8 are fixedly connected to the protruding sides of the lower end of the strapping body 1. The outer side of the ET base layer 7 is wrapped with a reinforcing fiber layer 6, and the outer side of the reinforcing fiber layer 6 is wrapped with a wear-resistant protective layer 3. The wear-resistant protective layer 3 is made of high-density polyethylene, and the wear-resistant protective layer 3 and the reinforcing fiber layer 6 are connected by extrusion molding. This allows the wear-resistant protective layer 3 to effectively improve the wear resistance of the strapping and extend its service life. The reinforcing fiber layer 6 is made of mesh glass fiber woven material, and the reinforcing fiber layer 6 and the PET base layer 7 are connected by hot melt adhesive. This allows the reinforcing fiber layer 6 to significantly improve the tensile strength of the strapping and meet the requirements for bundling heavy items. The inner wall of the PET base layer 7 is inlaid with reinforcing ribs 4. The reinforcing ribs 4 are made of polypropylene and are distributed in a cross structure on the inner wall of the PET base layer 7. This allows the reinforcing ribs 4 to further enhance the structural strength of the strapping and prevent the strapping from bending and breaking under stress.

[0016] Working principle: When using this type of PET plastic steel strapping, firstly, PET granules are melted and extruded to form a PET base material layer 7 during manufacturing. Then, a glass fiber woven mesh is bonded to the surface of the PET base material layer 7 with hot melt adhesive to form a reinforcing fiber layer 6. Finally, high-density polyethylene is extruded onto the surface of the reinforcing fiber layer 6 to form a wear-resistant protective layer 3. At the same time, anti-slip teeth 2 are pressed onto the surface of the wear-resistant protective layer 3. Engaging protrusions 8 and engagement grooves 5 are pressed onto the edges of both ends of the strapping body 1. Reinforcing ribs 4 are embedded simultaneously when the PET base material layer 2 is extruded. During winding, the engagement protrusions 8 can be inserted into the engagement grooves 5 to form a limiting engagement and winding. During packaging, the anti-slip teeth 2 can be used for anti-slip treatment. Moreover, during use, the wear-resistant protective layer 3, reinforcing ribs 4, and reinforcing fiber layer 6 can be used for tensile resistance treatment. This is the usage process of this type of PET plastic steel strapping.
