Description

Technical Field

[0001] This utility model belongs to the field of fabric testing technology and relates to a device for testing fabric performance. Background Technology

[0002] Elastic fabric, as one of the key materials in trampoline manufacturing, must undergo a series of rigorous tests throughout the production process to ensure its quality and performance. These tests include, but are not limited to, tensile tests, tear tests, and abrasion resistance tests. Each step is crucial because they collectively determine whether the fabric can meet the high standards required for trampoline use. Among these tests, the tensile test is indispensable, as it assesses the fabric's strength under tensile forces.

[0003] In existing tensile testing equipment, elastic fabrics usually need to be horizontally clamped between two clamping structures. Since the elastic fabric is suspended during installation, it is not convenient to keep the entire fabric flat, which makes the installation process inconvenient. Therefore, it is necessary to design a device for testing fabric performance. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a device for testing fabric performance.

[0005] Therefore, this utility model is implemented using the following technical solution: a device for testing fabric performance, comprising a base, characterized in that one end of the base is connected to one side of a tensile tester via a first upright, the other side of the tensile tester is connected to a first fixed rod, the other end of the base is connected to a horizontally arranged electric linear track via a second upright, a second fixed rod is fixed on the slide of the electric linear track, both the first and second fixed rods have clamping structures, an auxiliary platform is provided in the middle of the base via a lifting mechanism, both sides of the auxiliary platform have toothed rods, and the clamping structure has toothed notches that cooperate with the toothed rods.

[0006] The clamping structure includes an L-shaped clamping body, a lower pressure plate, and a screw. One end of the L-shaped clamping body is connected to a crossbar, and the screw is vertically threaded onto the crossbar. The upper end of the screw is connected to a handle, and the lower end of the screw is rotatably connected to the lower pressure plate via a connecting plate. The lower pressure plate is also slidably connected to one end of the L-shaped clamping body, and the lower pressure plate can abut against the other end of the L-shaped clamping body. The aforementioned toothed notch is arranged at the other end of the L-shaped clamping body.

[0007] The lifting mechanism includes a bracket, a servo motor, a lead screw, a nut, a guide column, and a guide sleeve. The bracket is installed in the middle of the base, the lower end of the guide column is installed on the bracket, the guide sleeve is slidably connected to the guide column, the lower end of the lead screw is rotatably installed on the bracket, and the lower end of the lead screw is also connected to the output shaft of the servo motor. The body of the servo motor is connected to the bracket, the nut is threaded onto the lead screw, and the auxiliary platform is connected to the nut and also to the guide sleeve.

[0008] The bracket is also equipped with a lower limit block, and an upper limit reinforcing rod is installed between the guide post and the lead screw.

[0009] An electrical control panel is also connected to the base, and the electric linear track, servo motor and tension gauge are all electrically connected to the electrical control panel via wiring.

[0010] Compared with existing technologies, this device for fabric performance testing has the following advantages: In this invention, the auxiliary platform is raised to be flush with the other end surface of the L-shaped clamping body. At this time, the toothed rod is located in the toothed notch. The fabric is laid flat on the auxiliary platform, and the toothed rod can provide support for the two edges of the fabric. By rotating the operating handle, the screw is driven to move, and the lower pressure plate clamps the edge of the fabric onto the L-shaped clamping body. Finally, the auxiliary platform moves downward and retracts. At this time, a tensile test can be performed. In this way, the fabric can be conveniently and flatly fixed between the two clamping structures. Attached Figure Description
