[0016] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the drawings of the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0017] Embodiment one:

[0018] As Figs. 1-3 The utility model discloses a paper packing belt, including composite belt 1, and the composite belt 1 includes paper tape 2 and hemp rope 3, and the composite belt 1 outside spiral wrapping has wear -resisting paper 4, and the paper tape 2 is composed of multilayer composite layer 5 laminated layer, and the composite layer 5 includes paper layer 6 and tensile layer 7, and the upper and lower sides of tensile layer 7 are all provided with paper layer 6. The material quality of wear -resisting paper 4 and paper layer 6 is kraft paper. Paper tape 2 is equipped with 3 composite layers 5, and the composite layer 5 is fixed through environmental protection glue cementation between the composite layer 5. The hemp rope 3 includes 3 thin ropes, and is formed in three-strand way. Tensile layer 7 is made of hemp fiber.

[0019] Through the above technical scheme, the utility model composite belt 1 includes paper tape 2 and hemp rope 3, and the paper tape 2 is composed of multilayer composite layer 5 laminated layer, and the composite layer 5 includes paper layer 6 and tensile layer 7, and wear -resisting paper 4 protects the composite belt 1 through spiral wrapping mode, makes paper tape 2 and hemp rope 3 form a whole, improves the tensile property of packing belt.

[0020] Embodiment two:

[0021] As Figs. 1-3 The utility model discloses a composite belt 1 is by paper tape 2 and hemp rope 3 composition. The outer side spiral of composite belt 1 is wrapped with wear -resisting paper 4, forms a complete outer layer structure. Paper tape 2 is by multiple composite layers 5 superposition, and every composite layer 5 includes paper layer 6 and tensile layer 7. Tensile layer 7 is located between the paper layer 6 of two sides, and constitutes a sandwich structure. Tensile layer 7 adopts hemp fiber to be made, and has higher tensile strength. Wear -resisting paper 4 and paper layer 6 all select kraft paper as raw material. In the making -up process, first hemp fiber is processed into tensile layer 7, then tensile layer 7 is clamped between two layers of kraft paper, and forms the basic composite layer 5 structure. Then, multiple composite layers 5 are superimposed together, and constitute the main part of paper tape 2. After paper tape 2 is made, hemp rope 3 is placed side by side with paper tape 2, and the core structure of composite belt 1 is formed. Finally, wear -resisting kraft paper is wrapped in the outer side of composite belt 1 in the spiral mode, and the whole packing belt is made. The multiple composite structure design improves the tensile property of packing belt significantly. Tensile layer 7 is made of hemp fiber, and has excellent tensile strength, can bear greater tension and is not easy to break. Tensile layer 7 is clamped between paper layer 6, which not only protects tensile layer 7, but also increases the overall thickness and strength. The superimposition of multiple composite layers 5 further enhances the structural stability and bearing capacity of paper tape 2. Hemp rope 3 itself has very high tensile strength, which greatly improves the overall tensile property of composite belt 1. This design overcomes the shortcomings of insufficient strength of traditional paper packing belt, so that the paper packing belt can be used in more high-strength application scenarios. The spiral wrapping design of wear -resisting paper 4 not only improves the wear resistance of packing belt, but also plays a protective role for the internal structure. The spiral wrapping mode makes paper tape 2 and hemp rope 3 form a whole, further enhancing the strength of the packing belt. At the same time, the use of wear -resisting paper 4 also improves the service life of the packing belt, reduces the damage caused by friction in the use process. The selection of kraft paper not only ensures the strength of the packing belt, but also maintains good environmental performance. The kraft paper has high tensile strength and breaking degree, and is easy to degrade, meeting the environmental requirements of modern packaging industry. The utility model discloses a multiple composite structure, hemp rope 3 reinforcement, wear -resisting paper 4 wrapping etc. design, while maintaining the environmental characteristics, significantly improve the tensile property.

[0022] Example three:

[0023] As Figs. 1-3As shown, both the abrasion-resistant paper 4 and the paper layer 6 of this utility model are made of kraft paper. Kraft paper is an unbleached paper with high strength and toughness. In this packing strap, the abrasion-resistant paper 4, as the outer layer material, needs to have good abrasion resistance and tear resistance. Kraft paper has a dense fiber structure and a smooth surface, which can effectively resist friction and external impact, making it very suitable for use as abrasion-resistant paper 4. At the same time, the natural brown appearance of kraft paper also gives the packing strap a unique aesthetic appeal. The paper layer 6, as an important component of the composite layer 5, is also made of kraft paper. The high strength of kraft paper allows the paper layer 6 to provide good support and protection for the tensile layer 7. Kraft paper has long fiber lengths and strong inter-fiber bonding, which gives the paper layer 6 excellent tensile strength and folding endurance. During the packing process, the paper layer 6 can effectively disperse stress and prevent breakage caused by local stress concentration. The selection of kraft paper also takes environmental factors into consideration. As an unbleached paper, the production process of kraft paper is relatively simple, energy-efficient, and has a small impact on the environment. Meanwhile, kraft paper is easy to recycle and degrade, meeting the requirements of the modern packaging industry for sustainable development. In the manufacturing process, kraft paper is first processed to an appropriate thickness and width for making abrasion-resistant paper 4 and paper layer 6. When making paper layer 6, the kraft paper needs to be cut to suitable dimensions to combine with tensile layer 7 to form composite layer 5. Abrasion-resistant paper 4 requires special treatment to enhance its abrasion resistance, and then it is cut into strips for spiral wrapping composite tape 1.

[0024] Example 4:

[0025] like Figs. 1-3 As shown, the paper tape 2 of this invention adopts a three-layer composite layer 5 design, with each composite layer 5 bonded and fixed together by environmentally friendly adhesive. This structural design significantly improves the overall tensile strength of the packing tape. During manufacturing, the tensile layer 7 is first placed between two paper layers 6, forming a basic sandwich structure. Then, environmentally friendly adhesive is used to bond the three layers together, forming a complete composite layer 5. This bonding method ensures a tight bond between the layers, avoiding the problem of layer separation during use. The environmentally friendly adhesive is chosen based on its excellent bonding performance and environmental characteristics. This adhesive does not contain harmful substances and has minimal environmental impact during use and disposal. Simultaneously, the environmentally friendly adhesive has good bonding strength, maintaining a stable bonding effect under various environmental conditions, ensuring the integrity of the composite layer 5 structure.

[0026] Example 5:

[0027] like Figs. 1-3As shown, the hemp rope 3 of this invention is composed of three thin ropes, formed by a three-strand twisting method. During the manufacturing process, the three thin ropes are first arranged in parallel, and then cross-wound at a fixed angle and rhythm. Each rope successively wraps around the other two, forming a spiral weave structure. This weaving method ensures that the three ropes are tightly connected and mutually supportive. The hemp rope 3, after being formed by the three-strand twisting, exhibits a uniform spiral texture. The three-strand structure significantly improves the tensile strength of the hemp rope 3. When the hemp rope 3 is subjected to tension, the three ropes simultaneously bear the stress and mutually transfer and disperse the force. This force distribution reduces stress concentration in a single area, lowering the risk of breakage.

[0028] Example 6:

[0029] like Figs. 1-3 As shown, the tensile layer 7 of this invention is made of hemp fiber. Hemp fiber was chosen as the material for the tensile layer 7 primarily based on its excellent mechanical properties and environmentally friendly characteristics. During the manufacturing process, the hemp fiber is first washed and combed to remove impurities and ensure the fibers are neatly arranged. Then, the treated hemp fiber is spread into a thin layer, with the fibers mainly arranged along the length of the packing strap. This directional arrangement improves the longitudinal strength of the tensile layer 7. The thickness of the tensile layer 7 is adjusted according to the required strength. The hemp fiber layer is bonded to the paper layer 6 by pressing or adhesive to form a unified structure. During the use of the packing strap, the hemp fiber tensile layer 7 plays a crucial role. When the packing strap is subjected to tension, the force is first transferred to the tensile layer 7. The high strength of the hemp fiber allows the tensile layer 7 to withstand most of the tensile stress, reducing the burden on the paper layer 6. The toughness of the hemp fiber also gives the tensile layer 7 a certain degree of elastic deformation capability, allowing it to slightly stretch under stress and preventing sudden breakage.
