Technical Field

[0001] This utility model relates to the field of nonwoven fabric testing technology, and in particular to a tensile testing device for automotive interior nonwoven fabrics. Background Technology

[0002] Automotive nonwoven fabric is a new generation of environmentally friendly material made from polypropylene (PP) and other materials. Produced through melt spinning and hot pressing processes, it possesses properties such as moisture resistance, breathability, flexibility, lightweight, flame retardancy, and biodegradability. It is widely used in automotive sound insulation felt, seat covers, trunk liners, air filters, and other components, making it an ideal alternative to traditional rubber or foam materials. During the production process, it is crucial to ensure that nonwoven fabrics can withstand the expected tensile forces in practical applications without breaking or excessive deformation, thereby guaranteeing product quality and safety. Therefore, a tensile testing device for automotive interior nonwoven fabrics needs to be designed to perform tensile testing. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tensile testing device for nonwoven fabrics used in automotive interiors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A tensile testing device for nonwoven fabrics for automotive interiors includes a main body, a placement rack installed on one side of the main body, and a ramp provided on one side of the main body. A first movable component is provided on the top of the main body, and a tensile component is connected and installed at the top of the first movable component. Two sets of second movable components are provided in the ramp, and a fixing component is connected and installed on the outside of the second movable components. The tensioning assembly includes a connecting seat, which is connected to the first moving assembly. A support rod is fixedly installed on the top of the connecting seat, and a connecting frame is connected to the top of the support rod. A push rod motor is fixedly installed on the top of the connecting frame. A tension detection pressure plate is connected to the output shaft of the push rod motor. A sensor is installed inside the connecting frame. The fixing component includes a movable frame, which contains an elastic element, and a fixing plate is connected and installed at the bottom of the elastic element.

[0005] Preferably, a placement groove is provided in the slope, and guide grooves are provided on both sides of the placement groove in the slope.

[0006] Preferably, both sides of the placement groove are designed with an arc shape to reduce friction with the non-woven fabric and provide protection.

[0007] Preferably, the guide groove is designed with an inclination and its top is connected to the fixing plate, which facilitates the outward movement of the fixing plate.

[0008] Preferably, both the first and second moving components consist of a drive motor and a lead screw, used to control the movement of the tensioning and fixing components, and the top of the lead screw is covered with a dustproof pad for protection.

[0009] Preferably, the tensile testing plate adopts a U-shaped structure design, and the sensor is located in the groove of the tensile testing plate, which can both fix the non-woven fabric and not affect the sensor's sensing function.

[0010] The beneficial effects of this utility model are: This invention allows for automatic tensile testing simply by placing the nonwoven fabric in the placement rack and pulling one end into the connecting rack. The fixing component moves inward on its own, using a fixing plate to fix the middle position of the nonwoven fabric. When the sensor detects the presence of the nonwoven fabric, it controls the tensile testing pressure plate to descend and automatically position the end of the nonwoven fabric. This reduces manual labor, is easy to operate, and is highly practical. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: Refer to Figure 1-6 A tensile testing device for automotive interior nonwoven fabric includes a main body 1. A placement rack 2 is installed on one side of the main body 1, and a ramp 3 is provided on one side of the main body 1. A placement groove is formed in the ramp 3. Both sides of the placement groove adopt an arc-shaped structure design to reduce friction with the nonwoven fabric and provide protection. Guide grooves are provided on both sides of the placement groove in the ramp 3. A first moving component 4 is provided on the top of the main body 1, and a tensile component 5 is connected and installed at the top of the first moving component 4. Two sets of second moving components 6 are provided in the ramp 3, and a fixing component 7 is connected and installed on the outside of the second moving components 6. The first moving component 4 and the second moving component 6 are both composed of a drive motor and a lead screw, which are used to control the movement of the tensile component 5 and the fixing component 7. The top of the lead screw is covered with a dustproof pad for protection. The tensile component 5 is wrapped with... The assembly includes a connecting seat 8, which is connected to the first moving component 4. A support rod 9 is fixedly installed on the top of the connecting seat 8, and a connecting frame 10 is connected to the top of the support rod 9. A push rod motor 11 is fixedly installed on the top of the connecting frame 10. A tensile detection pressure plate 12 is connected to the output shaft of the push rod motor 11. A sensor 13 is installed inside the connecting frame 10. The tensile detection pressure plate 12 adopts a U-shaped structure design, and the sensor 13 is located in the groove of the tensile detection pressure plate 12, which can both fix the non-woven fabric and not affect the sensor 13's sensing function. The fixing component 7 includes a moving frame 14, and an elastic element 15 is installed inside the moving frame 14. A fixing plate 16 is connected to the bottom of the elastic element 15. The guide groove adopts an inclined design, and its top is connected to the fixing plate 16, which facilitates the outward movement of the fixing plate 16.

[0015] Working principle: When in use, the non-woven fabric needs to be placed in the placement frame 2, and one end is pulled into the connecting frame 10. When the sensor 13 detects the non-woven fabric, it will open the push rod motor 11 to control the tension detection plate 12 to descend and fix the end of the non-woven fabric. Then, the first moving component 4 controls the tension component 5 to move a certain distance so that the non-woven fabric enters the placement groove of the ramp 3. The second moving component 6 is opened to control the moving frame 14 to move inward. The fixing plate 16 will then contact the top of the non-woven fabric through the elastic force of the elastic element 15 to fix the middle position of the non-woven fabric. Then, the tension component 5 continues to move, and the tension is detected by the tension detection plate 12. The non-woven fabric is manually checked for breakage or deformation.
