Description

Technical Field

[0001] This utility model relates to the technical field of anti-slip PET plastic steel strapping, specifically an anti-slip PET plastic steel strapping. Background Technology

[0002] Also known as strapping. Packaging strapping is made primarily of polyethylene, polypropylene resin, and cold-rolled steel strip, and sometimes nylon and polyester. It is produced through extrusion and unidirectional stretching, followed by heat treatment and bluing. Besides being used for sealing corrugated boxes, hot-rolled steel coils, and cold-rolled steel coils, it can also be used to bundle glass, pipes, materials, and water.

[0003] The existing patent document CN 216995767 U provides a non-slip PET plastic steel strapping, including a first strapping, a slot provided inside the first strapping, a card groove provided inside the first strapping, an insert strip inserted inside the slot, and a card block fastened inside the card groove.

[0004] However, existing strapping may oxidize and corrode if left unused for a long time, causing it to break when used again. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a non-slip PET plastic steel strapping to solve the problem of oxidation and corrosion of existing strapping mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip PET plastic steel strapping, comprising a main body and an anti-slip mechanism, wherein the anti-slip mechanism is fixedly installed inside the main body, the main body includes a strapping strap, a PET substrate, and short straps, wherein the PET substrate is fixedly installed on the strapping strap, and a plurality of short straps are fixedly installed on the surface of the strapping strap;

[0009] The anti-slip mechanism includes anti-slip texture, a reinforcing layer, and a wear-resistant layer. The anti-slip texture is fixedly installed on the outer surface of the packing strap, the reinforcing layer is fixedly installed on the outer surface of the PET substrate, and the wear-resistant layer is fixedly installed on the outer surface of the reinforcing layer.

[0010] Furthermore, the main structure also includes a roller and a support rod, with the roller fixedly installed on the inner surface of the packing strap and the support rod fixedly installed on the inner side of the roller.

[0011] Furthermore, the main body mechanism also includes toothed grooves and buckles, with toothed grooves fixedly installed at both ends of the short belt, and buckles fixedly installed in the toothed grooves.

[0012] Furthermore, the main structure also includes serrations, and serrations are fixedly installed on both sides of the packing strap.

[0013] Furthermore, the anti-slip mechanism also includes an anti-ultraviolet layer and a weather-resistant coating. The anti-ultraviolet layer is fixedly installed on the surface of the PET substrate, and the weather-resistant coating is fixedly installed on the surface of the PET substrate.

[0014] Furthermore, the anti-slip mechanism also includes anti-slip protrusions and anti-slip grooves. The anti-slip protrusions are fixedly installed on the surface of the anti-slip texture, and the anti-slip grooves are fixedly installed between the anti-slip protrusions.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. High strength and extremely high tensile strength, approaching that of steel strapping of the same specification and approximately twice that of PP strapping. It possesses excellent impact resistance and ductility, capable of withstanding significant tensile forces, ensuring products remain secure and do not detach during transportation and storage. High toughness, possessing plastic properties, and excellent flexibility, it absorbs energy through deformation during transport, preventing items from scattering due to rigid breakage. Good weather resistance, with a melting point of 255-260℃, it maintains stable performance and dimensional stability at -110-120℃. It is also resistant to high temperatures and moisture, unlike steel strapping which is prone to rusting due to moisture, and its tensile strength is not significantly affected by changes in ambient temperature. Easy to handle and environmentally friendly, lightweight and easy to transport; compact in size, saving storage space. Used PET strapping is easily recyclable, meeting environmental requirements and is reusable. Economical and cost-effective, with a density only about 1 / 6 that of steel strapping, the price per unit length is relatively low, effectively reducing packaging costs. High strength and tensile properties enhance cargo safety. With tensile strength comparable to steel strapping, PET molecular chains are highly oriented and crystallized through a 3-5 times longitudinal stretching process, achieving a tensile strength of 500-800 MPa, approaching that of steel strapping. It can withstand binding forces of 500-2000 kg, significantly reducing the risk of breakage during heavy cargo transportation. Excellent impact resistance: PET material is tougher than steel strapping, absorbing energy through slight deformation during cargo vibration or collisions, preventing unraveling due to rigid breakage. Creep resistance ensures long-term stability: PET polymer chains move slowly at room temperature, with a creep deformation rate of <3% / year. Even when binding heavy objects for extended periods, it maintains constant tension, avoiding the loosening caused by stress relaxation common in traditional plastic strapping. The anti-slip structure significantly enhances the reliability of strapping and greatly improves the surface friction coefficient. The diamond / grid-like protrusions (height 0.1-0.3 mm, roughness Ra 1.5-3.0 μm) formed by embossing rollers or laser etching increase the surface friction coefficient of the strap from 0.3-0.4 for smooth PET to 0.5-0.7, which is close to that of rubber.

[0017] 2. In practical applications, when bundling smooth metal parts or plastic boxes, the anti-slip texture can embed into the microscopic grooves on the surface of the object, forming a "mechanical interlock" to prevent slippage and displacement. During inclined or bumpy transportation, the anti-slip structure can effectively resist the sliding force of the goods along the tangent of the strap, making it especially suitable for scenarios such as sudden braking or turning of transport vehicles. It is compatible with various bundling tools, and the texture design is compatible with the bite structure of manual strapping machines, pneumatic strapping machines, and fully automatic strapping equipment. For example, the serrations of a pneumatic strapping machine can embed into the grooves of the strap texture, increasing the engagement depth during locking by 30% to 50% compared to smooth straps, further improving the connection strength. Weather resistance and chemical stability expand application scenarios. With a wide temperature range adaptability, PET's glass transition temperature is approximately 70℃, and after crystallization, its temperature resistance range reaches -30~120℃ (short-term tolerance to 150℃), superior to PP tape (-10~80℃). It maintains flexibility and does not crack in cold storage (-20℃); in high-temperature workshops or transportation environments (such as 80℃ inside a summer truck), it will not experience tensile weakness due to softening. Corrosion resistance and aging resistance: PET's stable molecular structure and acid and alkali resistance (pH 4~10) are superior to PP and steel tape, making it suitable for corrosive environments such as chemical raw materials and food. After adding UV absorbers, the tensile strength retention rate after 5 years of outdoor exposure is >85% (PP tape only 60%~70%), suitable for open-air storage or sea freight strapping. Lightweight and easy to handle improve packaging efficiency and reduce manual labor intensity. At the same strength, PET tape density (1.38g / cm³) is significantly lower. 3 Only steel strip (7.85g / cm) 3 Weighing only 1 / 5 to 1 / 6 of the material, this strapping tape of the same length is over 70% lighter, making it easier for workers to handle and operate, especially suitable for work at heights or in confined spaces. It is compatible with automated equipment, with uniform tape thickness (tolerance ±0.05mm) and neat edges. Photoelectric sensors accurately position the tape feeding length, enabling high-speed operation of 30-50 strapping passes per minute in fully automated production lines, increasing efficiency by 5-8 times compared to manual PP strapping.
