Technical Field

[0001] The utility model relates to the technical field of textile fabric detection, in particular to a bidirectional stretching mechanism for textile fabrics. Background Art

[0002] After the production of textile fabrics, in order to test their relevant properties, they are usually subjected to relevant performance tests. Among them, the tensile performance test of textile fabrics is one of the common test items;

[0003] When conducting tensile property testing, the textile fabric is usually subjected to biaxial stretching to perform corresponding tests on the warp and weft threads of the textile fabric.

[0004] After searching, a Chinese patent (publication number: CN220339860U) discloses a fabric production stretch detection device, which includes a workbench, a biaxial stretching component and a fixed component. The top of the workbench is fixedly connected with a mounting plate. The biaxial stretching component includes a rotating column, a diamond rod, a slide groove, a slide plate, a hinged plate and a drive motor. The top of the workbench is rotatably installed with a rotating column, and a diamond rod is fixedly sleeved on the outer wall of the rotating column. The top of the diamond rod is hingedly installed with a hinged plate. The bottom of the workbench is fixedly connected with a drive motor. The drive motor drives the rotating column to rotate, the rotating column drives the diamond rod to rotate, and the diamond rod drives the hinged plate to move relative to each other. The biaxial stretching component can be used to stretch the fabric, and the fixed component can be used to fix the fabric.

[0005] When performing bidirectional testing on textile fabrics, if the textile fabrics are clamped in both directions simultaneously, when the textile fabrics are deformed, the testing data is easily affected. Therefore, the utility model proposes a bidirectional stretching mechanism for textile fabrics. Utility Model Content

[0006] The utility model aims to provide a bidirectional stretching mechanism for textile fabrics.

[0007] The technical problem solved by the utility model is: how to avoid the problem of affecting the detection data when the fabric is deformed due to clamping the fabric during bidirectional detection of the textile fabric.

[0008] The utility model can be realized by the following technical scheme: a bidirectional stretching mechanism for textile fabrics, comprising a placing table, four sets of testing boxes and four sets of fixing frames;

[0009] The upper surface of the placement table is set to be rectangular, for placing the rectangular textile fabric to be tested, and each edge of the textile fabric is parallel to the corresponding edge of the upper surface of the placement table;

[0010] The four groups of detection boxes are respectively installed on one side of each edge of the placement table;

[0011] An extension mechanism is installed inside each of the detection boxes, a detection component is installed at the output end of each of the extension mechanisms, a clamping component is installed on one side of the detection component, and a clamping hole is provided inside the clamping component;

[0012] The four groups of fixing frames are respectively arranged on one side adjacent to each detection box, and a supporting assembly is installed inside each fixing frame, and each fixing frame is respectively parallel to a side edge corresponding to the placement table;

[0013] When the support component supports the corresponding side edge of the textile fabric, the support component extends between the corresponding edge of the placement table and the detection box in the corresponding direction;

[0014] After the textile fabric is placed on the upper side of the placement table, its edge extends to the outside of the placement table, and each supporting component is moved out from the inside of the fixed frame to the side corresponding to the edge of the placement table, and supports the edge of the textile fabric on the corresponding side;

[0015] When the clamping assembly clamps the textile fabric, the clamping hole inside it is sleeved on the outside of the corresponding supporting assembly. After the clamping assembly and the textile fabric are clamped, the corresponding supporting assembly is pulled out from the clamping hole in the clamping assembly.

[0016] A further technical improvement of the utility model is that the extension mechanism comprises a first stroke cylinder, and two ends of the first stroke cylinder are respectively connected to the detection box and the detection assembly.

[0017] A further technical improvement of the utility model is that: at least one set of fixed rods parallel to the first stroke cylinder is installed inside the detection box, and the same number of sliding racks as the fixed rods are installed on the side of the detection assembly;

[0018] The sliding frame is slidably connected to the outer side of the corresponding fixed rod. When the first stroke cylinder drives the detection component and the clamping component to move, the sliding frame slides synchronously along the corresponding fixed rod.

[0019] A further technical improvement of the utility model is that the support assembly comprises a second stroke cylinder installed inside the fixing frame, and a support roller is installed at the output end of the second stroke cylinder.

[0020] A further technical improvement of the utility model is that a receiving groove is opened inside the support roller, and after the output end of the second stroke cylinder is connected to the support roller, the connecting part between the second stroke cylinder and the support roller is located inside the receiving groove, which is used to increase the stroke range of the support roller.

[0021] A further technical improvement of the utility model is that: the outer side of the support roller is rotatably connected with a plurality of contact rollers;

[0022] The rotation direction of each contact roller is the same as the movement direction of the support roller.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] When the utility model detects the textile fabric, the textile fabric is stretched by the related structures inside the two groups of detection boxes on the same axial direction of the side of the placement table, so that the textile fabric is detected in the corresponding direction, and when the textile fabric is placed, the edge of the textile fabric can be supported by the support components inside each fixing frame, and after the clamping component clamps the part of the corresponding side of the textile fabric, the support component in the corresponding direction can be drawn out from the clamping hole in the corresponding clamping component, so as to avoid affecting the clamping component during detection;

[0025] During the detection, the support components on the other two sides continue to support the edge of the textile fabric, and at the same time, it is convenient for the clamping components in the corresponding direction to clamp the textile fabric after the detection direction is changed later.
