Description

Technical Field

[0001] The utility model relates to the technical field of tensile testing, in particular to a non-woven fabric elasticity testing device. Background Art

[0002] Non-woven fabric is a kind of non-woven fabric that does not go through the traditional textile process, but uses chemical fibers or natural fibers as raw materials and forms textiles by directly heating, pressing, chemical treatment and other methods to interweave or bond the fibers together. The tensile strength of non-woven fabric is one of the important indicators to evaluate its performance. The tensile testing of non-woven fabric usually includes parallel tensile testing and vertical tensile testing to measure the physical and mechanical properties of non-woven fabric in the tensile direction, such as strength, elastic modulus, breaking elongation and elongation at break, etc. The existing non-woven fabric elasticity testing devices have the following deficiencies: clamping and fixing the non-woven fabric through a clamping mechanism easily causes the non-woven fabric to fold and bend, and at the same time, the test sample cannot be ensured to be completely flat and without wrinkles. When the non-woven fabric folds and bends during the test, it will cause inaccurate testing. Content of the Utility Model

[0003] The problem to be solved by the utility model is that the non-woven fabric elasticity testing device cannot ensure the flatness of the non-woven fabric.

[0004] To solve the above technical problems, the utility model provides a non-woven fabric elasticity testing device, which includes an installation shell. One side of the installation shell is provided with an installation hole, and the installation hole extends to the inside of the installation shell. Two clamping blocks are vertically arranged inside the installation hole. The two clamping blocks include an upper clamping block arranged at the upper part of the installation hole and a lower clamping block arranged at the lower part of the installation hole. A tensile sensor is arranged at the bottom of the lower clamping block. A clamping mechanism is arranged on the two clamping blocks, and a flattening mechanism for stretching the non-woven fabric is arranged on the clamping mechanism.

[0005] Preferably, the flattening mechanism includes a flattening block, an elastic member, a connecting rod and a handle. The flattening block is installed with the elastic member, and one end of the elastic member away from the flattening block is installed with the connecting rod. The number of the flattening blocks is two, and the tops of the two connecting rods are installed through the handle.

[0006] Preferably, the clamping mechanism includes a clamping plate, a rotating rod and a guide rod. The clamping plate is rotatably connected with the rotating rod, and one end of the rotating rod away from the clamping plate is in threaded connection with the clamping block. The two ends of the guide rod are arranged in the clamping block and are slidably connected with both sides of the clamping plate.

[0008] Preferably, a second sliding groove is formed on the adjacent sides of the clamping plate and the clamping block, and the flat block is slidably connected to the second sliding groove.

[0009] Preferably, a transmission block is arranged inside the mounting hole, and a tension sensor mounted on the lower clamping block is installed at the bottom of the transmission block.

[0010] Preferably, a lead screw is rotatably connected inside the mounting hole. The lead screw is slidably connected to the transmission block. The transmission block is slidably connected to the inside of the mounting shell, and a driving device is arranged at the bottom of the lead screw.
