Description

Technical Field

[0001] This invention relates to the field of artificial leather testing technology, and in particular to a device for testing the tensile strength of artificial leather. Background Technology

[0002] Artificial leather is a synthetic material that mimics the appearance and texture of natural leather. It is usually composed of one or more layers of polyvinyl chloride, polyurethane or other synthetic resins combined with a base material. It is widely used in the manufacture of clothing, furniture and other products. It has the characteristics of low cost, environmentally friendly and controllable production process and easy maintenance. During the production and processing of artificial leather, various tests need to be carried out on artificial leather, such as tensile strength test, which is used to evaluate the material's resistance to external tensile force, deformation and breaking strength, etc., which is crucial in the application of product safety and durability.

[0003] Existing patent CN219957152U discloses a leather stretching detection device, including a worktable, a stretching device, and a pressing device. The stretching device includes a transverse stretcher and a longitudinal stretcher. Both the transverse and longitudinal stretchers include two symmetrically arranged clamping assemblies. One clamping assembly is slidably connected to the worktable. A telescopic cylinder for controlling the movement of the clamping assembly is connected to the rear of the clamping assembly. The pressing device is located in the center of the worktable and includes a hydraulic cylinder and a top component. A central hole for the movement of the top component is opened in the center of the worktable. The output end of the hydraulic cylinder is connected to the top component. This utility model has a reasonable and simple structure, strong practicality, and can realize the transverse and longitudinal stretching detection of leather.

[0004] The above structure can detect both transverse and longitudinal tension. However, when artificial leather is stretched, it can only be tested in one direction. When artificial leather is used in special environments that require bending, one-way tension testing cannot meet the needs of the bending environment. Therefore, bending testing experiments are required for artificial leather. One-way tension testing cannot fully understand the overall performance of artificial leather, easily overlooks potential weaknesses, reduces the accuracy of experimental data, and leads to product failure in practical applications, affecting product quality and reducing the product's market competitiveness.

When the simulation component is not activated, the force-applying component pulls the clamping components, achieving unidirectional detection. When the simulation component provides bending, the control system controls the height adaptation component and the angle adaptation component, causing the detection component to adapt to the changes in the force-applying component, achieving bending detection.

[0016] The beneficial effects of this invention are as follows: This invention performs tensile testing on artificial leather, requiring the measurement of data such as the leather's thickness. During unidirectional stretching, the simulation component remains stationary, allowing the artificial leather to pass between two contact components, with both ends secured to clamping components. During the stretch test, a force-applying component is activated, forcing it to pull the clamping components, thus stretching the artificial leather. After stretching, the leather's thickness gradually decreases. The contact components then dynamically detect this thickness, causing minute changes. An amplification component amplifies the data, which is then captured by an industrial camera and transmitted to [the relevant authority / organization]. The control system analyzes and outputs data to detect the thickness of the artificial leather during unidirectional tensile testing. During bending tensile testing, after the artificial leather is installed, the simulation component is activated, lifting the artificial leather and causing it to bend. To prevent the artificial leather from being subjected to force from the simulation component, the simulation component drives the adjustment component to move, bringing the force-applying component to a suitable position. Since the distances from the clamping component to the simulation component and the height adaptation component to the simulation component are determined, once the height lifted by the simulation component is determined, the control system uses the principle of similar triangles to adjust the height adaptation component and the angle adaptation component. The artificial leather is brought into contact with the contact component, forming an initial contact state. During the stretching test, the force application component is activated, forcing it to pull the clamping component, thus stretching the artificial leather. After stretching, the thickness of the artificial leather gradually decreases. Since the distance the clamping component moves is fixed, while the lifting height of the simulation component remains constant, the control system uses the principle of similar triangles to gradually adjust the height adaptation component and the angle adaptation component, enabling the contact component to dynamically detect the thickness of the artificial leather. Under the action of the amplification component, the detection component detects the amplified data. An industrial camera captures the data and transmits it to the control system. The data is analyzed and output to complete the detection of the thickness of artificial leather under tensile testing in a bending environment. In summary, the artificial leather tensile testing equipment of this application can realize the thickness detection of artificial leather under unidirectional tension. It can also utilize the principle of similar triangles to force the control system to respond quickly and realize the adaptive adjustment of the device, thereby realizing the thickness detection of artificial leather under bending environment, meeting the needs of various testing environments, improving the versatility of the device, comprehensively understanding the overall performance of artificial leather, timely discovering the potential weaknesses of artificial leather, improving the adaptability of artificial leather, improving the accuracy of experimental data, improving product quality, and improving the market competitiveness of products.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention. Example

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention discloses a tensile strength testing device for artificial leather, comprising a support frame 1, an adjustment component 2 mounted on the support frame 1, a force-applying component 3 mounted on the adjustment component 2, a clamping component 4 mounted on the force-applying component 3, a simulation component 5 mounted on the support frame 1 to provide bending degree, the simulation component 5 being connected to the adjustment component 2 and located between the two clamping components 4, a height adaptation component 6 electrically connected to a control system mounted on the support frame 1, an angle adaptation component 7 electrically connected to the control system mounted on the height adaptation component 6, a contact component 8 for contacting the artificial leather mounted on the angle adaptation component 7, an amplification component 9 connected to the contact component 8 mounted on the angle adaptation component 7, and a detection component 10 for detecting thickness mounted on the angle adaptation component 7, the detection component 10 being connected to the amplification component 9; wherein, when the simulation component 5 is not activated, the force-applying component 3 pulls the clamping component 4 to achieve a unidirectional detection effect; when the simulation component 5 provides bending degree, the control system controls the height adaptation component 6 and the angle adaptation component 7, so that the detection component 10 adapts to the change of the force-applying component 3, achieving a bending detection effect.

[0021] Working Principle: For tensile testing of artificial leather, data such as thickness need to be measured. During unidirectional stretching, the simulation component 5 remains stationary, allowing the artificial leather to pass between the two contact components 8, securing both ends of the leather to the clamping components 4. During the stretching test, the force application component 3 is activated, forcing it to pull the clamping components 4, thus stretching the artificial leather. After stretching, the thickness of the artificial leather gradually decreases. The contact components 8 then dynamically detect the thickness, causing minute changes. Under the amplification of the component 9, the detection component 10 detects the amplified data, which is then captured by an industrial camera. The data is transmitted to the control system, which analyzes and outputs the data to complete the detection of the artificial leather thickness during unidirectional tensile testing. During bending and stretching, after the artificial leather is installed, the simulation component 5 is activated, causing it to lift the artificial leather and bend it. To prevent the artificial leather from being subjected to force from the simulation component 5, the simulation component 5 drives the adjusting component 2 to move, causing the force-applying component 3 to move to a suitable position. Since the distances from the clamping component 4 to the simulation component 5 and from the height-adjusting component 6 to the simulation component 5 are determined, once the lifting height of the simulation component 5 is determined, the control system uses the principle of similar triangles to adjust the height-adjusting component 6 and the angle-adjusting component... Adjustments are made to align the artificial leather with the contact component 8, establishing initial contact. During stretching detection, the force application component 3 is activated, forcing it to pull the clamping component 4, thus stretching the artificial leather. After stretching, the thickness of the artificial leather gradually decreases. Since the distance the clamping component 4 moves is fixed, while the lifting height of the simulation component 5 remains constant, the control system uses the principle of similar triangles to gradually adjust the height adaptation component 6 and the angle adaptation component 7, enabling the contact component 8 to dynamically detect the thickness of the artificial leather. Under the action of the amplification component 9, the detection component 10 detects the amplified data. The data is then captured by an industrial camera and transmitted to [the relevant authority / system]. The control system analyzes and outputs data to complete the detection of the thickness of artificial leather under tensile testing in a bending environment. In summary, this application's artificial leather tensile testing device can detect the thickness of artificial leather under unidirectional tension. Furthermore, by utilizing the principle of similar triangles, it forces the control system to respond quickly and adapt to the device, thereby enabling the detection of the thickness of artificial leather under bending conditions. This meets the needs of various testing environments, improves the device's versatility, provides a comprehensive understanding of the overall performance of artificial leather, promptly identifies potential weaknesses in artificial leather, enhances the adaptability of artificial leather, improves the accuracy of experimental data, improves product quality, and enhances the product's market competitiveness.

[0028] like Figure 6 and Figure 8 As shown, the artificial leather tensile strength testing device of the present invention includes a contact component 8 comprising a sliding rod 801 slidably disposed on a support frame 703.

[0030] like Figure 6 and Figure 9 As shown, the artificial leather tensile strength testing device of the present invention includes an amplification component 9 comprising a rotating gear 901 connected to a support frame 703 by a bearing, the rotating gear 901 meshing with a contact spur rack 805, a shaft 902 connected to the support frame 703 by a bearing, a rotating gear 903 meshing with the rotating gear 901 fixedly sleeved on the shaft 902, the diameter of the rotating gear 901 being larger than the diameter of the rotating gear 903, and a rotating gear 904 meshing with a detection gear 1004 fixedly sleeved on the shaft 902, the diameter of the rotating gear 904 being larger than the diameter of the detection gear 1004.

[0031] Working principle: To perform tensile testing on artificial leather, it is necessary to test data such as the thickness of the artificial leather. During unidirectional stretching, the hydraulic lifting rod 501 does not move, that is, the simulated roller 503 does not contact the artificial leather, allowing the artificial leather to pass between the two contact rollers 803. The two ends of the artificial leather are placed between clamping block one 402 and clamping block two 404 respectively. Rotating the threaded rod two 403 causes the threaded rod two 403 to drive clamping block two 404 closer to clamping block one 402. Under the action of the teeth 405, the artificial leather is clamped, and at this time the artificial leather is just in a horizontal state. During the tensile test, the hydraulic push rod 301 is activated. The output end of the hydraulic push rod 301 pulls the tensile monitoring instrument 302, which in turn drives the connecting column 303 to move. The connecting column 303 then pulls the support block 401 to move, thereby causing the clamping block 402 and clamping block 404 to pull the artificial leather, thus achieving a stretching effect on the artificial leather. After stretching, the thickness of the artificial leather gradually decreases. At this time, the contact roller 803 moves closer to the artificial leather, causing the contact roller 803 to drive the connecting block 802 and the sliding rod 801 to move closer to the artificial leather. The contact spring 804 is stretched, and the sliding rod 801 drives the contact rack 805 to move. 05 drives rotating gear 1 901 to rotate, rotating gear 1 901 drives rotating gear 2 903 to rotate, rotating gear 2 903 drives shaft 902 and rotating gear 3 904 to rotate, rotating gear 3 904 drives detection gear 1004 to rotate, detection gear 1004 drives detection rod 1001 to rotate, detection rod 1001 drives detection pointer 1002 to rotate, so that detection pointer 1002 rotates to a reasonable position on the surface of dial 1003, and magnified data is obtained. The data is captured by an industrial camera and transmitted to the control system. The control system analyzes the data and outputs it, completing the detection of artificial leather thickness in unidirectional tensile strength testing. During bending and stretching, after the artificial leather is installed, the hydraulic lifting rod 501 is activated. The output end of the hydraulic lifting rod 501 drives the mounting frame 502 to move, which in turn drives the simulation roller 503 to move. The simulation roller 503 moves upward to lift the artificial leather, thus causing the artificial leather to bend. Since the simulation roller 503 exerts a force on the artificial leather when lifting it, in order to prevent the artificial leather from deforming due to the force of the simulation roller 503, when the simulation roller 503 moves to a specified height, the mounting frame 502 drives the connecting rod 504 to move. The connecting rod 504 drives the vertical rack 505 to move. The vertical rack 505 drives the adjusting gear 203 to rotate. The adjusting gear 203 drives the threaded rod 201 to rotate. The rotation of the threaded rod 201 causes the adjusting block 202 to move. The adjusting block 202 drives the force application component 3 and the clamping component 4 to move to a reasonable position, so that the artificial leather forms a reasonable bending state. Since the distances from clamping component 4 to simulation component 5 and from height adaptation component 6 to simulation component 5 are both fixed, and the height of simulation component 5 is also fixed, the artificial leather is located on the hypotenuse of the triangle. The control system will quickly acquire data and use the principle of similar triangles to adjust height adaptation component 6 and angle adaptation component 7. During adjustment, the electric push rod 601 is activated, causing the output end of the electric push rod 601 to drive the lifting block 602 to move to a reasonable and determined height. The lifting block 602 drives the angle adaptation component 7, contact component 8, amplification component 9 and detection component 10 to move to a reasonable height, completing the height adjustment. At the same time, the angle motor 701 is activated. The output shaft of the angle motor 701 rotates, driving the angle rotation shaft 702 to rotate. The angle rotation shaft 702 drives the support frame 703 to rotate at a reasonable angle, realizing the angle adjustment, so that the artificial leather is flush with the contact component 8, forming the initial state of contact, that is, the two contact rollers 803 are in symmetrical and uniform contact with the artificial leather. During the tensile test, the hydraulic push rod 301 is activated. The output end of the hydraulic push rod 301 pulls the tensile monitoring instrument 302, which in turn drives the connecting column 303 to move. The connecting column 303 then pulls the support block 401 to move, thereby causing the clamping block 1 402 and clamping block 2 404 to pull the artificial leather. Under the guidance of the guide roller 407, the artificial leather is stretched and bent. After the artificial leather is stretched, its thickness gradually decreases. Since the distance of the clamping component 4 is fixed, while the distance from the height adaptation component 6 to the simulation component 5 and the lifting height of the simulation component 5 remain unchanged, the control system uses the principle of similar triangles to gradually adjust the height adaptation component 6 and the angle adaptation component 7. This allows the contact roller 803 to perform follow-up detection of the thickness of the artificial leather. Under the action of the amplification component 9, the detection component 10 detects the amplified data. The data is captured by an industrial camera and transmitted to the control system. The control system analyzes the data and outputs the results, completing the detection of the artificial leather thickness during the tensile test under bending conditions.

[0032] This solution enables thickness detection of artificial leather under unidirectional tensile stress. Furthermore, by utilizing the principle of similar triangles, it forces the control system to respond quickly and adapt to the device, thereby achieving thickness detection of artificial leather under bending conditions. This meets the needs of various testing environments, enhances the device's versatility, provides a comprehensive understanding of the overall performance of artificial leather, promptly identifies potential weaknesses, improves the adaptability of artificial leather, increases the accuracy of experimental data, enhances product quality, and strengthens the product's market competitiveness.
