Description

Technical Field

[0001] The invention belongs to the technical field of glass fiber testing equipment, and in particular relates to a tensile strength testing device for a finished glass fiber product. Background Art

[0002] As a raw material that is widely used in modern society, glass fiber can be used to make many kinds of finished products, such as glass fiber cloth, mesh cloth, fiber tube, etc. In order to conduct quality inspection on the finished products produced by glass fiber, it is often necessary to use a detection device to inspect the finished glass fiber products. For example, to test the tensile strength of the finished glass fiber products, it is necessary to place the finished glass fiber products on the detection device and clamp them with a fixture, and then control the movement of the fixture to inspect the finished glass fiber products.

[0003] During use, some existing detection devices place both ends of the finished glass fiber product in a fixture and clamp the finished glass fiber product in the fixture by controlling the threaded rod on the fixture. However, due to the different thicknesses of different finished glass fiber products, when the thickness of the finished glass fiber product is relatively large, the finished glass fiber product can easily fall off the fixture during the detection process if it is only squeezed and fixed by the threaded rod.

At this time, since the support rod 35 is in contact with the top of the base 1, the support plate 33 cannot rotate, and the part of the finished glass fiber product that is not on the two lower clamping plates 22 can be supported by the support plate 33, so as to avoid the staff from holding the unclamped part of the finished glass fiber product with one hand when the finished glass fiber product is clamped and fixed by the upper clamping plate 7 and the lower clamping plate 22, so as to avoid the finished glass fiber product from falling off between the upper clamping plate 7 and the lower clamping plate 22 during the clamping and fixing process.

At this time, the two supporting plates 33 hold a part of the finished glass fiber product, and then push the upper clamping plate 7 to move to the top of the lower clamping plate 22. At this time, the L-shaped connecting plate 14 that is movably fitted with the upper clamping plate 7 drives the movable plate 13 to move in the circular slide groove 12 on the fixed ring 11, and the protrusion 15 on the movable plate 13 will move the fitting plate 18, the swivel 17, and the linkage plate 19 rotate around the fixed rod 16. At this time, the rotating plate 30 fixedly connected to the linkage plate 19 moves upward, that is, the rotating plate 30 pushes the lower clamping plate 22 to rotate upward, and the glass fiber preparation product can be clamped and fixed by the upper clamping plate 7 and the lower clamping plate 22. Then, by controlling the arc clamping plate 26 to fit the fixed gear ring 8 on the outer wall of the rotating shaft 6, the positions of the upper clamping plate 7 and the lower clamping plate 22 are fixed, and the traction component 3 can be controlled to move in the translation groove 2 to detect the tensile strength of the glass fiber preparation product.
