Description

Technical Field

[0001] This utility model relates to the field of mesh material technology, and in particular to a device for testing the tensile strength of low-transmittance mesh materials. Background Technology

[0002] Low-transmittance mesh materials are typically woven from fabrics, metal wires, or other composite materials, and undergo special coating or heat treatment to increase their tensile strength and durability. They must maintain a certain level of strength and morphological stability under external forces, wind pressure, or physical tension. Therefore, tensile strength is a crucial indicator for evaluating the performance of this type of material. Tensile strength measures a material's ability to resist failure under tensile force. For low-transmittance mesh materials, tensile strength directly affects their service life, stability, and safety in practical applications. For example, in the construction industry, low-transmittance mesh materials are often used in sunshades, curtains, and other devices, applications requiring the material to withstand strong wind pressure and external forces. In the transportation or industrial sectors, low-transmittance mesh materials are more commonly used as protective netting, conveyor belts, etc., requiring the material to be resistant to breakage and deformation under tensile force. Therefore, to ensure the safety and reliability of low-transmittance mesh materials, their tensile strength must be rigorously tested before the product leaves the factory. This not only helps assess the material's quality but also provides users with more reliable usage assurance. Utility Model Content

[0003] The purpose of this invention is to address the issue that low-transmittance mesh materials are prone to slippage, loosening, or instability during tensile strength testing due to their typically soft or elastic nature, which can affect the accuracy of the test results. The first clamping device in this solution (including an upper clamping plate, a lower clamping plate, clamping pins, and locking bolts) ensures the mesh material is stably fixed during tensile testing by uniformly distributing clamping force, thus avoiding the problem of material slippage or loosening.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: A tensile strength testing device for low light transmittance mesh materials, comprising a support frame, a tensioning device fixedly connected to one side of the upper end of the support frame, a fixing device provided on the opposite side of the upper end of the support frame to the tensioning device, and movable wheels provided at the four corners of the bottom of the support frame; the tensioning device includes a rotating motor, a rotating wheel provided at the output end of the rotating motor, several transmission wheels provided on both sides of the rotating wheel, a transmission belt passing through the rotating wheel and the transmission wheels, a lead screw connected to both sides of the transmission wheels, an I-shaped fixing member provided on the lead screw, a rotating shaft provided on both sides of the I-shaped fixing member, a tensioner fixedly connected to the I-shaped fixing member, and a first clamping device provided on one side of the upper end of the I-shaped fixing member, the first clamping device being able to clamp according to the thickness and characteristics of the material. The device allows for precise adjustment to ensure the stable fixation of the mesh material. The structure of the upper and lower clamping plates can be precisely adjusted according to testing requirements, ensuring a firm grip and preventing material slippage or loosening during tensile testing, which could affect test results. Locking bolts secure the clamping and ensure even distribution of clamping force during operation. The device utilizes a transmission system consisting of rotating and drive wheels, transmitting torque via a lead screw, enabling precise tension adjustment. This design is highly effective for testing the tensile strength of low-transmittance mesh materials under different tensile forces. The tension can be adjusted according to different material requirements, ensuring testing flexibility and versatility. The I-shaped fixing component and tensioner work together to accurately measure the tensile deformation of the material during force transmission and clamping. Combined with automated tension control, testers can obtain accurate tensile strength data, facilitating material performance analysis.

[0005] Furthermore, the first clamping device includes an upper clamping plate, a lower clamping plate at the lower end of the upper clamping plate, and a plurality of clamping pins arranged at equal intervals between the upper clamping plate and the lower clamping plate. Locking bolts are provided on both sides of the upper and lower clamping plates, and sliding blocks are fixedly connected to both sides of the bottom of the lower clamping plate. The clamping pins are arranged at equal intervals between the upper and lower clamping plates to ensure that the clamping force is evenly distributed to different parts of the clamped object. Due to the even arrangement of the clamping pins, the problem of excessive local force is avoided, and a stable and uniform clamping effect can be provided without damaging the material. This is particularly important for the fixation of precision parts, improving clamping accuracy. The sliding blocks are fixed to both sides of the bottom of the lower clamping plate, giving the clamping device a certain degree of adaptability and flexibility. The sliding blocks can help the lower clamping plate make fine adjustments during the clamping process, ensuring the stability of the equipment during clamping.

[0006] Furthermore, the fixing device includes a U-shaped fixing member, a columnar binding member is fixedly connected to the inner side of the U-shaped fixing member, a second clamping device is provided on one side of the columnar binding member, and fixing pins are evenly arranged on the binding member for fixing and binding the mesh material, so as to make it more secure.

[0007] Furthermore, the second clamping device has the same structure as the first clamping device.

[0008] Furthermore, the upper end of the support frame is provided with sliding grooves on both sides, and the sliding block is assembled and connected with the sliding grooves on both sides of the upper end of the support frame.

[0009] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0010] 1. This equipment utilizes a transmission system comprised of rotating wheels, drive wheels, lead screws, and I-shaped fixing components to precisely adjust the tension applied to the mesh material. A rotating motor drives the rotating wheels, transmitting torque to the I-shaped fixing components via a drive belt and lead screw, making tension adjustment both flexible and precise. This design ensures uniform tension distribution, allowing for accurate testing of materials of different types and thicknesses, and improving the accuracy of tensile strength data.

[0011] 2. The first clamping device in the equipment (including the upper clamping plate, lower clamping plate, and clamping pins) is designed to ensure that the mesh material is stably fixed before tensile force is applied, and that the clamping force is evenly distributed. The even arrangement of the clamping pins avoids excessive local stress and reduces the risk of material damage. The locking bolts provide stable clamping, ensuring even distribution of clamping force during clamping and preventing the mesh material from slipping or loosening during stretching, thus ensuring a stable and reliable testing process.

[0012] 3. The equipment is designed to accommodate different materials and thicknesses. The clamping and fixing devices can be adjusted according to material characteristics. For example, the first clamping device can be adjusted based on the material's thickness and properties to ensure a stable fixation. Furthermore, the cooperative design of the sliding block and the support frame's groove allows the clamping device to have a fine-tuning function, improving stability and flexibility during clamping, making it particularly suitable for mesh materials of different sizes and shapes.

Locking bolts secure the clamping and ensure even distribution of clamping force during operation. The device utilizes a transmission system consisting of rotating and drive wheels, transmitting torque via a lead screw, enabling precise tension adjustment.

[0020] Furthermore, the first clamping device 29 includes an upper clamping plate 291, a lower clamping plate 292 at the lower end of the upper clamping plate 291, and a plurality of clamping pins 293 arranged at equal intervals between the upper clamping plate 291 and the lower clamping plate 292. Locking bolts 294 are provided on both sides of the upper clamping plate 291 and the lower clamping plate 292. Sliding blocks 295 are fixedly connected to both sides of the bottom of the lower clamping plate 292.

A second clamping device 33 is provided on one side of the columnar binding member 32.

Power is transmitted to the lead screws 25 on both sides through several transmission wheels 23 and transmission belts 24. The lead screws 25 generate linear displacement by rotation, and transmit torque to the I-shaped fixing member 26. A tensioner 28 is installed on the I-shaped fixing member. The tensioner 28 is responsible for applying a uniform and adjustable tension to the mesh material. By rotating the lead screw, the magnitude of the tension can be adjusted as needed to ensure that the tension applied during the test meets the material requirements and test standards. The cooperation between the tensioner 28 and the I-shaped fixing member 26 enables the tension to be accurately transmitted to the mesh material, achieving precise tensile control.
