Description

Technical Field

[0001] This utility model relates to the field of packaging materials technology, and in particular to a PET plastic steel belt with anti-slip function. Background Technology

[0002] PET strapping is currently the most widely used packaging strap. Traditional PET strapping has poor anti-slip properties, making it prone to slipping on surfaces after packing. This results in weak connection strength of the strapping buckles. Furthermore, during transportation, bumps can easily cause the strapping buckles to slip, leading to loose connections and breakage, requiring repacking. This is not only time-consuming and labor-intensive but can also result in lost goods.

[0003] To this end, the patent specification with publication number CN220200099U discloses a PET plastic steel strap with anti-slip function, including a plastic steel strap body. The upper surface of the plastic steel strap body is provided with multiple anti-slip grooves arranged linearly, and the lower surface of the plastic steel strap body is provided with anti-slip ridges that are adapted to the anti-slip grooves. The vertical cross section of the anti-slip ridges is a right triangle. By setting the triangular anti-slip ridges, the friction between the plastic steel strap body and the object is increased after the object is packaged, thereby improving the strength of the packaged item.

[0004] The aforementioned PET plastic steel belt with anti-slip function still has shortcomings in use. First, its anti-slip groove design is not reasonable, only providing unidirectional anti-slip function and failing to achieve multi-directional anti-slip; second, the design of its anti-slip groove affects the structural strength of the belt. In view of this, the inventors hope to optimize and improve it. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a PET plastic steel belt with anti-slip function.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A PET plastic steel belt with anti-slip function includes a PET base layer and a tear-resistant layer bonded to its lower side. The upper side of the PET base layer is provided with a plurality of anti-slip groove arrays at equal intervals. Each anti-slip groove array includes four cavities, referred to as the first cavity, the second cavity, the third cavity, and the fourth cavity, respectively. The first cavity and the third cavity are diagonally distributed and their bottom slopes gradually rise from the outside to the inside along the length direction of the PET base layer. The second cavity and the fourth cavity are diagonally distributed and their bottom slopes gradually rise from the outside to the inside along the width direction of the PET base layer.

[0007] Furthermore, in the aforementioned PET plastic steel belt with anti-slip function, the thickness of the PET base layer is 0.8 to 2 mm, and the PET base layer is obtained by stretching and molding PET material after high-temperature extrusion.

[0008] Furthermore, in the aforementioned PET plastic steel belt with anti-slip function, the maximum depth of the first, second, third, and fourth grooves is 1 / 2 to 2 / 3 of the thickness of the PET base layer.

[0009] Furthermore, in the aforementioned PET plastic steel belt with anti-slip function, the cross-sections of the first and third grooves along the length of the PET base layer are right-angled triangles.

[0010] Furthermore, in the aforementioned PET plastic steel belt with anti-slip function, the cross-sections of the second and fourth grooves along the width direction of the PET base layer are right-angled triangles.

[0011] Furthermore, in the aforementioned PET plastic steel belt with anti-slip function, the thickness of the tear-resistant layer is 0.3 to 0.4 mm, and the tear-resistant layer is made of fiberglass cloth.

[0012] The beneficial effects of this utility model are: 1. Multi-directional anti-slip function: Compared with the existing PET plastic steel strapping which only has a unidirectional anti-slip function, this solution achieves multi-directional anti-slip through a unique anti-slip groove array design, which improves the stability after packaging.

[0013] 2. Ensure the strength of the belt structure: The anti-slip groove is designed in a reasonable way to reduce the impact on the strength of the belt structure while achieving the anti-slip function, ensuring that the plastic steel belt is not easily damaged during use.

[0014] 3. Reasonable material selection: The PET base layer is made of PET material extruded at high temperature and then stretched into shape, and the tear-resistant layer is made of fiberglass cloth. The materials have good performance and help to improve the overall performance of the plastic steel belt.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-2 As shown, this embodiment provides a PET plastic steel belt with anti-slip function, including a PET base layer 1 and an anti-tear layer 2 bonded to its lower side. The upper side of the PET base layer 1 is provided with a plurality of anti-slip groove arrays at equal intervals. Each anti-slip groove array includes four cavities, which are respectively referred to as the first cavity 101, the second cavity 102, the third cavity 103 and the fourth cavity 104. The first cavity 101 and the third cavity 103 are diagonally distributed and their bottom slopes gradually rise from the outside to the inside along the length direction of the PET base layer 1. The second cavity 102 and the fourth cavity 104 are diagonally distributed and their bottom slopes gradually rise from the outside to the inside along the width direction of the PET base layer 1.

[0020] In this embodiment, the thickness of the PET base layer 1 is 0.8–2 mm. The PET base layer 1 is obtained by high-temperature extrusion and stretching of PET material. PET material itself has certain strength and toughness; after the high-temperature extrusion and stretching process, its structural performance is further improved, providing good basic strength for the plastic-steel belt.

[0021] In this embodiment, the maximum depth of the first groove 101, the second groove 102, the third groove 103, and the fourth groove 104 is 1 / 2 to 2 / 3 of the thickness of the PET base layer. This depth design ensures that the anti-slip grooves can play an effective anti-slip role, while avoiding excessive weakening of the structural strength of the PET base layer due to excessive depth. This allows the plastic steel belt to maintain good overall structural strength while possessing anti-slip function.

[0022] In this embodiment, the cross-sections of the first cavity 101 and the third cavity 103 along the length of the PET substrate layer are right-angled triangles.

[0023] In this embodiment, the cross-sections of the second cavity 102 and the fourth cavity 104 along the width direction of the PET substrate layer are right-angled triangles.

[0024] In this embodiment, the thickness of the tear-resistant layer 2 is 0.3–0.4 mm, and the tear-resistant layer 2 is made of fiberglass cloth. Fiberglass cloth has the characteristics of high strength and tear resistance. When bonded to the underside of the PET base layer 1, it can effectively enhance the tear resistance of the PET steel belt and further improve the overall structural strength of the PET steel belt, making it less prone to damage when subjected to external forces.

[0025] The multi-directional anti-slip principle of this embodiment is as follows: PET base layer 1: As the main structure of the plastic steel belt, it has several anti-slip groove arrays equidistantly arranged on its upper side. Each anti-slip groove array contains four cavities, namely the first cavity 101, the second cavity 102, the third cavity 103 and the fourth cavity 104.

[0026] The first cavity 101 and the third cavity 103 are diagonally distributed, and their bottom slopes gradually rise from the outside to the inside along the length of the PET base layer 1. When the plastic strip tends to slide along its length, this raised design creates a force that resists sliding between the object and the bottom slope of the cavity, thus providing anti-slip protection along the length. Simultaneously, the cross-sections of the first cavity 101 and the third cavity 103 along the length of the PET base layer are right-angled triangles, further enhancing the anti-slip effect along the length.

[0027] The second cavity 102 and the fourth cavity 104 are diagonally distributed, with their bottom slopes gradually rising from the outside to the inside along the width direction of the PET base layer 1. When the plastic-coated steel belt tends to slide in the width direction, this design generates a force that resists sliding between the object and the bottom slope of the cavity, achieving anti-slip in the width direction. Moreover, the cross-sections of the second cavity 102 and the fourth cavity 104 along the width direction of the PET base layer are right-angled triangles, further enhancing the anti-slip performance in the width direction. Through the synergistic effect of the four cavities, multi-directional anti-slip of the plastic-coated steel belt is achieved.

[0028] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to specific implementation methods. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
