Description

Technical Field

[0001] This utility model relates to the field of industrial transmission technology, specifically to a composite material transmission belt. Background Technology

[0002] A search revealed existing technology (application number: CN202320123456.7), which describes "a single-material transmission belt, integrally molded from nitrile rubber, with increased thickness to improve load-bearing capacity." This utility model, through a thickened design using a single material, improves the belt's load-bearing capacity to a certain extent. However, while the existing technology improves overall sealing, heat preservation, and temperature distribution uniformity, thus improving the overall preheating effect, it still has some shortcomings: a single material cannot be adapted to multiple application scenarios, such as nitrile rubber not meeting hygiene standards in the food industry; there is no dedicated bonding structure between layers, making delamination likely during long-term high-load operation; there is no dedicated sealing design, allowing external impurities to easily penetrate and degrade performance; poor buffering performance results in high vibration and noise during operation, affecting equipment lifespan. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a composite material transmission belt.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a composite material transmission belt, comprising: a belt body, an inner ring contacting a pulley, a surface functional layer, and four layers inside the belt body.

[0005] As a further description of the above technical solution:

[0006] The belt body includes a surface functional layer, which is located on the outermost layer and directly contacts the outside world. The material is selected according to the application scenario. Nitrile rubber is commonly used in heavy-duty industrial scenarios, food-grade silicone or polyurethane is used in the food industry, and aramid canvas or polytetrafluoroethylene coating is used in high-precision transmission scenarios.

[0007] As a further description of the above technical solution:

[0008] The surface functional layer encloses the core load-bearing layer.

[0009] As a further description of the above technical solution:

[0010] The core load-bearing layer is located in the innermost layer of the belt body. It is mainly made of high-strength fibers such as carbon fiber, glass fiber or aramid fiber, and is the most important layer in the conveyor belt. An external reinforcing adhesive layer is placed on the outside.

[0011] As a further description of the above technical solution:

[0012] The reinforcing adhesive layer is made of modified rubber adhesive or thermoplastic elastomer, with one side fixed to the core load-bearing layer and the other side connected to the elastic buffer layer.

[0013] As a further description of the above technical solution:

[0014] The elastic buffer layer is located between the reinforcing adhesive layer and the sealing layer, and is generally made of natural rubber, nitrile rubber or polyurethane elastomer.

[0015] As a further description of the above technical solution:

[0016] The sealing layer is located on the outermost layer inside the surface functional layer. It is usually made of polyvinyl chloride, butyl rubber, etc., and can prevent external dust, moisture, oil and other contaminants from entering the belt.

[0017] This utility model has the following beneficial effects:

[0018] 1. High adaptability, stability, and durability: Through layered design and selection of suitable materials for different functional layers, the problem of single-material belts being unable to meet the needs of multiple application scenarios in existing technologies is solved. The surface functional layers can meet the specific requirements of different scenarios such as heavy-duty industrial applications, food processing, and high-precision transmission, while ensuring the basic transmission performance of the belt. It effectively eliminates the connection gaps between the core load-bearing layer and the elastic buffer layer caused by material differences, ensuring a stable connection between layers and preventing interlayer peeling or slippage during long-term high-load operation. This ensures the coordinated work of each layer during power transmission, reduces energy loss caused by interlayer loosening, and significantly improves the overall structural strength and service life of the belt.

[0019] 2. Enhanced Protection and Expanded Applications: The sealing layer effectively blocks external moisture, dust, and chemical media from intruding into the belt, preventing corrosion or contamination of internal layers. It also prevents performance degradation caused by the evaporation or loss of internal adhesives and matrix materials, ensuring long-term stable operation of the belt in complex environments. This solves the problem of impurity intrusion and performance degradation caused by the lack of a dedicated sealing design in existing technologies. The core load-bearing layer, made of high-strength fiber material, bears the main tensile force during transmission, ensuring that the belt does not overstretch or break under high loads, maintaining transmission accuracy and avoiding transmission ratio errors caused by deformation.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0027] Example 1:

[0028] like Figures 1 to 2 As shown, this embodiment provides a composite material transmission belt, including: a belt body 1, an inner ring contact pulley, a surface functional layer 2, and the belt body 1 containing four layers inside.

[0029] In this embodiment, the reinforcing adhesive layer 4 constitutes a composite material transmission belt according to this application.

[0030] It should also be understood that existing technologies typically use nitrile rubber for integral molding, which increases the load-bearing capacity by increasing the thickness. However, the material is singular and cannot be adapted to multiple scenarios. There is no special bonding structure between the layers, and delamination is likely to occur during long-term high-load operation. There is no special sealing design, and external impurities can easily enter the interior, leading to performance degradation. The buffering performance is poor, and there is a lot of vibration and noise during operation, which affects the service life of the equipment.

[0031] In this embodiment, the user installs the belt body 1 into the desired position and initiates its movement. The surface functional layer 2 directly contacts the pulley, transmitting power through stable friction, ensuring transmission efficiency while protecting the belt's internal structure from external wear, contamination, and corrosion. The core load-bearing layer 3 bears the main tension during transmission and is the core load-bearing component for power transmission, ensuring that the belt does not overstretch or break under high loads, maintaining transmission accuracy, and preventing transmission ratio errors due to deformation. The reinforcing adhesive layer 4 effectively eliminates the connection gap between the core load-bearing layer 3 and the elastic buffer layer 5 caused by material differences, preventing interlayer peeling or slippage during belt operation, ensuring that each layer works collaboratively during power transmission, and reducing energy loss due to interlayer loosening. Furthermore, a stable connection also improves the overall structural strength of the belt, making it more resistant to frequent bending and torsion. The elastic buffer layer 5 buffers the impact and vibration generated during pulley meshing, reducing noise, reducing the instantaneous load on the core load-bearing layer 3, extending its service life, making power transmission smoother, and preventing wear of equipment components due to impact. The sealing layer 6 blocks external moisture, dust, chemical media, etc. from entering the belt, preventing the layers inside the belt body 1 from being corroded or contaminated; the sealing layer 6 also prevents the adhesive and matrix materials inside the belt from degrading due to volatilization or loss, ensuring the long-term stability of the belt.

[0032] Specifically, the belt body 1 includes a surface functional layer 2, which is located on the outermost layer and directly contacts the outside. The material is selected according to the application scenario. Nitrile rubber is commonly used in heavy-duty industrial scenarios, food-grade silicone or polyurethane is used in the food industry, and aramid canvas or polytetrafluoroethylene coating is used in high-precision transmission scenarios.

[0033] In this embodiment, the second surface functional layer is annular, covering the outermost layer of the belt body and in direct contact with the outside world. Nitrile rubber is used in heavy-duty industrial scenarios, food-grade silicone or polyurethane is used in the food industry, and aramid canvas or polytetrafluoroethylene coating is used in high-precision transmission scenarios. It adapts to different scenarios through its own material properties and resists external wear, pollution and corrosion.

[0034] Specifically, the surface functional layer 2 encloses the core load-bearing layer 3.

[0035] In a preferred embodiment, the core load-bearing layer 3, which is the same width as the belt body and is one layer, is wrapped inside the surface functional layer 2 and is located inside the surface functional layer. It is wrapped by the surface functional layer and serves as the load-bearing core, maintaining its structural stability through the protection of the surface functional layer.

[0036] Example 2:

[0037] Based on Example 1, in order to better transmit its power, a core load-bearing layer 3 is provided inside the belt body 1;

[0038] Specifically, the core load-bearing layer 3 is located in the innermost layer of the belt body 1. Its main material is high-strength fibers such as carbon fiber, glass fiber or aramid fiber. It is the most important layer in the conveyor belt, and an external reinforcing adhesive layer 4 is placed on the outside.

[0039] In this embodiment, the core load-bearing layer 3 is located in the innermost layer of the belt body, and there is only one layer. The material is high-strength fiber such as carbon fiber, glass fiber or aramid fiber, and an outer reinforcing adhesive layer 4 is provided on one side. The high-strength fiber bears the main tensile force during the transmission process, ensuring that the belt does not overstretch or break under high load.

[0040] Specifically, the reinforcing adhesive layer 4 is made of modified rubber adhesive or thermoplastic elastomer, with one side fixed to the core load-bearing layer 3 and the other side connected to the elastic buffer layer 5.

[0041] With this configuration, the reinforcing adhesive layer 4 is layered, consisting of one layer, and is made of modified rubber adhesive or thermoplastic elastomer. One side is bonded and fixed to the core load-bearing layer 3, and the other side is bonded and connected to the elastic buffer layer 5. The core load-bearing layer and the elastic buffer layer are connected by their own adhesiveness to prevent interlayer peeling or slippage.

[0042] Example 3:

[0043] Based on Example 2, in order to ensure the safety and durability of the belt body 1, a sealing layer 6 is provided outside the elastic buffer layer 5;

[0044] Specifically, the elastic buffer layer 5 is located between the reinforcing adhesive layer 4 and the sealing layer 6, and is generally made of natural rubber, nitrile rubber or polyurethane elastomer.

[0045] Among them, the elastic buffer layer 5, which is a single layer, is made of natural rubber, nitrile rubber or polyurethane elastomer, and is located between the reinforcing adhesive layer 4 and the sealing layer 6; it reduces the instantaneous load on the core load-bearing layer by using its own elastic buffer pulley to reduce the impact and vibration generated by the engagement of the pulley.

[0046] Specifically, the sealing layer 6 is located on the outermost layer inside the surface functional layer 2. The material is usually polyvinyl chloride, butyl rubber, etc., which can prevent external dust, moisture, oil and other contaminants from entering the belt.

[0047] In this embodiment, the sealing layer 6 is a single layer made of polyvinyl chloride, butyl rubber, etc., and is located outside the elastic buffer layer 5 and inside the surface functional layer 2. It blocks external dust, moisture, and oil through its own material, preventing them from entering the belt and corroding or contaminating the structure of each layer.

[0048] In actual use, the user installs the belt body 1 into the desired position and starts it in motion. The surface functional layer 2 directly contacts the pulley, transmitting power through stable friction, ensuring transmission efficiency while protecting the internal structure of the belt from external wear, contamination, and corrosion. The core load-bearing layer 3 bears the main tension during transmission and is the core load-bearing component for power transmission. It ensures that the belt does not overstretch or break under high load, maintains the belt's transmission accuracy, and avoids transmission ratio errors caused by deformation. The reinforcing adhesive layer 4 effectively eliminates the connection gap between the core load-bearing layer 3 and the elastic buffer layer 5 due to material differences, preventing interlayer peeling or slippage during belt operation. This ensures that each layer works collaboratively during power transmission and reduces energy loss caused by interlayer loosening. In addition, the stable connection also improves the overall structural strength of the belt, making it more resistant to frequent bending and torsion. The elastic buffer layer 5 can buffer the impact and vibration generated when the pulley meshes, reduce noise, reduce the instantaneous load on the core load-bearing layer 3, extend its service life, make power transmission smoother, and avoid wear of equipment parts caused by impact. The sealing layer 6 blocks external moisture, dust, chemical media, etc. from entering the belt, preventing the layers inside the belt body 1 from being corroded or contaminated; the sealing layer 6 also prevents the adhesive and matrix materials inside the belt from degrading due to volatilization or loss, ensuring the long-term stability of the belt.
