Description

Technical Field

[0001] This utility model belongs to the field of adhesive material production technology, specifically relating to a noise-reducing, high-tensile strength machine assembly line tape. Background Technology

[0002] Adhesive tape is primarily used in assembly lines to fix and connect various components, ensuring smooth production. Specific applications of adhesive tape in assembly lines include: First, it is commonly used to fix and connect various components, ensuring stability and safety during production. For example, in electronics manufacturing, tape is used to fix electronic components and connect circuit boards; in automobile manufacturing, it is used for body sealing and noise reduction. Second, in the packaging stage of assembly lines, tape is used for sealing boxes and packing, ensuring the safety of products during transportation. For example, in the cardboard packaging of e-commerce, home appliances, and food industries, tape sealing machines are widely used to improve packaging efficiency and quality. Third, adhesive tape has multiple functions, including packaging, fixing, bonding, and masking. In assembly lines, tape can meet different needs, such as fixing paper and labels, connecting two objects, and temporarily masking unwanted objects. Currently, the tapes used in assembly lines are generally industrial tapes. Industrial tapes mainly consist of an adhesive layer on a substrate. Existing tape structures have limited functionality, poor noise reduction performance, and generate significant noise when used on assembly lines. Furthermore, these tapes have poor tensile strength and durability, making them prone to breakage and tearing. Therefore, it is objectively necessary to develop a noise-reducing, high-tensile-strength tape for assembly line operations with a reasonable structural design, good noise reduction effect, and high tensile strength and durability. Summary of the Invention

[0003] The purpose of this utility model is to provide a noise-reducing, high-tensile strength conveyor belt for assembly line operations that has a reasonable structural design, good noise reduction effect, and good tensile durability.

[0004] The purpose of this utility model is achieved as follows: it includes a substrate layer and an adhesive layer. From top to bottom, an upper sound-absorbing layer, an upper reinforcing layer, a crack-resistant layer, a lower reinforcing layer, and a lower sound-absorbing layer are sequentially bonded between the substrate layer and the adhesive layer. The upper and lower sound-absorbing layers have the same structure. Sound-absorbing cavities are provided inside the upper and lower sound-absorbing layers and filled with sound-absorbing material. Multiple sets of first reinforcing components are arranged at equal intervals between the crack-resistant layer and the upper and lower reinforcing layers. Multiple sets of second reinforcing components are arranged on the crack-resistant layer between two adjacent first reinforcing components. Protective layers are bonded to both sides of the substrate layer, the upper sound-absorbing layer, the upper reinforcing layer, the crack-resistant layer, the lower reinforcing layer, the lower sound-absorbing layer, and the adhesive layer.

[0005] Compared with traditional industrial tapes, the advantages of this invention are as follows: First, this invention optimizes the tape structure. An upper sound-absorbing layer and a lower sound-absorbing layer are provided between the substrate layer and the adhesive layer. The sound-absorbing materials within these layers have a good sound absorption and noise reduction effect, which can reduce the sound generated when tearing the tape during assembly line operations, achieving a lower noise level. Second, an upper reinforcing layer, a breakage-resistant layer, and a lower reinforcing layer are provided between the upper and lower sound-absorbing layers. The first and second reinforcing components on the breakage-resistant layer can enhance the tensile strength of the tape, making it more durable and efficient. It is not prone to breakage during tearing operations, has good tensile strength, and significantly improves the tensile strength and durability of the tape. The adhesive layer can improve the tape's adhesion and flexibility. The protective layer can connect the base layer, upper sound-absorbing layer, upper reinforcing layer, anti-breakage layer, lower reinforcing layer, lower sound-absorbing layer and adhesive layer into one, preventing the tape from cracking or delaminating during use. It can further improve the tape's connection strength and tensile strength, and is easy to promote and use. Attached Figure Description

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention.

[0011] like Figures 1-3As shown, this utility model includes a substrate layer 1 and an adhesive layer 2. From top to bottom, an upper sound-absorbing layer 3, an upper reinforcing layer 4, a fracture-resistant layer 5, a lower reinforcing layer 6, and a lower sound-absorbing layer 7 are sequentially bonded between the substrate layer 1 and the adhesive layer 2. The upper sound-absorbing layer 3 and the lower sound-absorbing layer 7 have the same structure. Sound-absorbing cavities are provided inside the upper sound-absorbing layer 3 and the lower sound-absorbing layer 7. The sound-absorbing cavities are filled with sound-absorbing material 8. Multiple sets of first reinforcing components are arranged at equal intervals between the fracture-resistant layer 5 and the upper reinforcing layer 4 and the lower reinforcing layer 6. Multiple sets of second reinforcing components are arranged on the fracture-resistant layer 5 between two adjacent first reinforcing components. Protective layers 9 are bonded to both sides of the substrate layer 1, the upper sound-absorbing layer 3, the upper reinforcing layer 4, the fracture-resistant layer 5, the lower reinforcing layer 6, the lower sound-absorbing layer 7, and the adhesive layer 2.

[0012] The manufacturing process of this utility model is as follows: Based on the structure of the tape, an upper sound-absorbing layer 3, an upper reinforcing layer 4, an anti-breakage layer 5, a lower reinforcing layer 6, and a lower sound-absorbing layer 7 are pre-fabricated. Then, adhesive is applied to the bottom surface of the substrate layer 1. The adhesive can be a strong industrial adhesive used in the prior art. The upper sound-absorbing layer 3 is then bonded to the substrate layer 1. Adhesive is then applied to the bottom surface of the upper sound-absorbing layer 3, allowing the upper reinforcing layer 4 to bond to the upper sound-absorbing layer 3. Next, following a top-to-bottom order, the anti-breakage layer 5, the lower reinforcing layer 6, and the lower sound-absorbing layer 7 are bonded sequentially. Finally, the adhesive layer 2 is bonded. Thus, the tape of this structure is completed. The sound-absorbing material 8 provided in the upper sound-absorbing layer 3 and the lower sound-absorbing layer 7 of this utility model has good sound absorption properties. The noise reduction effect can reduce the sound generated when tearing tape during assembly line operations, achieving the goal of lower noise. The upper reinforcing layer 4, the anti-breakage layer 5, and the lower reinforcing layer 6 in this utility model can enhance the tensile strength of the tape, making it less prone to breakage during tearing operations. The adhesive layer 2 can improve the adhesion and flexibility of the tape. The protective layer 9 can connect the base material layer 1, the upper sound-absorbing layer 3, the upper reinforcing layer 4, the anti-breakage layer 5, the lower reinforcing layer 6, the lower sound-absorbing layer 7, and the adhesive layer 2 into one, preventing the tape from cracking or delaminating during use, and further improving the connection strength and tensile strength of the tape.

[0013] Furthermore, to improve the connection strength between the upper reinforcing layer 4, the anti-fracture layer 5, and the lower reinforcing layer 6, and to prevent the tape from breaking, the first reinforcing component includes an upper reinforcing strip 51 and a lower reinforcing strip 52. The upper reinforcing strip 51 is disposed on the top surface of the anti-fracture layer 5, and the lower reinforcing strip 52 is disposed on the bottom surface of the anti-fracture layer 5. The upper reinforcing strip 51 and the lower reinforcing strip 52 are arranged symmetrically. An upper reinforcing groove corresponding to the upper reinforcing strip 51 is machined on the bottom surface of the upper reinforcing layer 4, and the upper reinforcing strip 51 is installed in the upper reinforcing groove. A lower reinforcing groove corresponding to the lower reinforcing strip 52 is machined on the top surface of the lower reinforcing layer 6, and the lower reinforcing strip 52 is installed in the lower reinforcing groove. The upper reinforcing strip 51 is installed in the upper reinforcing groove using adhesive, and the lower reinforcing strip 52 is installed in the lower reinforcing groove using adhesive. This improves the connection strength between the anti-fracture layer 4 and the upper and lower reinforcing layers 4 and 6, thereby improving the strength of the tape and enhancing its tensile strength and durability.

[0014] Furthermore, the upper reinforcing strip 51 and the lower reinforcing strip 52 are made of glass fiber. Glass fiber has high strength, which can improve the tensile strength of the anti-fracture layer. Preferably, the shape of the upper reinforcing strip 51 and the lower reinforcing strip 52 can be reasonably selected based on the manufacturing difficulty. The cross-sectional shape of the upper reinforcing strip 51 and the lower reinforcing strip 52 is a trapezoidal, rectangular, square or triangular structure.

[0015] Furthermore, the second reinforcing component includes reinforcing blocks 53 and connecting ribs 54. Multiple mounting grooves are spaced apart on the anti-fracture layer 5. The reinforcing blocks 53 are symmetrically installed on both sides within the mounting grooves. The connecting ribs 54 are installed between two reinforcing blocks 53. The mounting grooves on the bottom and top surfaces of the connecting ribs 54 are filled with adhesive. The reinforcing blocks 53 and connecting ribs 54 are distributed inside the anti-fracture layer 5, which enhances the strength of the end face of the anti-fracture layer 5, improves its tensile strength, and solves the problem of tape breakage. Preferably, the reinforcing blocks 53 and connecting ribs 54 are made of carbon fiber. Carbon fiber also has good angle properties, and when used in conjunction with glass fiber, it can improve the tensile performance of the tape due to its high strength.

[0016] To further enhance the strength of the tape, a reinforcing layer 10 is provided between the adhesive layer 2 and the lower sound-absorbing layer 7. The bottom surface of the reinforcing layer 10 is provided with filling grooves at intervals, and the top surface of the adhesive layer 2 is provided with a protrusion structure corresponding to the filling grooves. Preferably, the reinforcing layer 10 is made of graphene film material. By using the reinforcing layer 10 made of graphene film material, the overall tensile strength of the tape can be enhanced.

[0017] Furthermore, the substrate layer 1 is made of modified PPS plastic, which significantly improves the tensile strength and durability of the tape. The adhesive layer 2 is made of acrylic adhesive, which has high tackiness and improves the tape's adhesion, making it less prone to falling off after use. The upper sound-absorbing layer 3 and the lower sound-absorbing layer 7 are made of epoxy resin, which has good sound absorption. The upper reinforcing layer 4 and the lower reinforcing layer 6 are both made of nylon polyester fabric, which has good toughness and greatly enhances the tape's strength and tensile strength, making it less prone to breakage and extending its service life. The anti-breakage layer 5 is made of silicone, which has good flexibility and improves the tape's flexibility, making it easier to use. The sound-absorbing material 8 is made of glass wool, which has good sound absorption and is widely used in tapes. The protective layer 9 is made of glass fiber, which has good bonding performance and can prevent the tape from cracking and delaminating during use.
