Description

Technical Field

[0001] The utility model relates to the technical field of fabric test and detection equipment, in particular to a pressing plate mechanism of a stiffness tester for fabric test and detection. Background Technique

[0002] The stiffness of a fabric is the ability of the fabric to resist the change of shape in the bending direction. The bending performance of the fabric is an important physical parameter for us to study the stiffness, drapability, softness and other properties of the fabric. The fabric stiffness is an important index for people to evaluate the fabric performance.

[0003] For the test of the fabric stiffness, generally a rectangular test cloth sample is placed on the horizontal workbench 10, as Figure 1 shown. The long axis of the test cloth sample is parallel to the long axis of the workbench 10. The pressing plate mechanism 20 advances the test cloth sample along the long axis direction of the workbench 10, so that it extends out of the workbench 10 and bends under its own weight. The head end of the extended part is suspended in the air. The pressing plate mechanism 20 presses a part of the test cloth sample still on the workbench 10. When the head end of the extended part of the test cloth sample reaches the inclined plane with an inclination angle of 41.5° to the horizontal line, the extended length is equal to twice the bending length of the test cloth sample, and thus the bending length can be calculated.

[0004] In the prior art, in order to improve the friction coefficient, the pressing plate of the pressing plate mechanism 20 is made of rubber material. When testing the stiffness of the fabric, when pressing on the base platform and reciprocatingly translating, static electricity is easily generated. The cloth sample will stick to the pressing plate of the equipment due to static electricity adsorption, affecting the test data. And the pressing plate mechanism 2 of the prior art lacks an operating mechanism and is inconvenient to lift during use. Content of the Utility Model

[0005] In order to overcome the deficiencies in the prior art, the utility model provides a pressing plate mechanism of a stiffness tester to solve the above problems in the prior art.

[0006] The utility model is realized by the following technical solutions:

[0007] A pressing plate mechanism of a stiffness tester includes a pressing plate and a pressing plate seat. The pressing plate is arranged on the pressing plate seat. The pressing plate seat is connected with the translation driving mechanism of the stiffness tester through a rotating shaft. Metal contacts are arranged on the pressing plate, and the metal contacts are all connected with the pressing plate seat through metal conductors. The pressing plate seat, the rotating shaft and the translation driving mechanism are all made of metal material. The translation driving mechanism is electrically connected with the metal shell of the stiffness tester, and the static electricity is released through grounding of the metal shell.

[0008] By arranging metal contacts on the rubber material pressing plate and realizing the release of static electricity through the metal material pressing plate seat, rotating shaft, translation driving mechanism and metal shell, the adsorption of the test cloth sample on the pressing plate of the equipment is effectively avoided, and the accuracy and reliability of the test data are improved.

[0009] The bottom surface of the pressing plate is provided with bump structures, and the metal contacts are located at the lowermost ends of the bump structures. By adopting the bump structures, the contact stability between the pressing plate and the cloth sample can be improved, the sliding between the pressing plate and the cloth sample can be avoided, and the generation of static electricity can be reduced.

[0010] The pressing plate seat is provided with a T-shaped sliding groove, the top surface of the pressing plate has a T-shaped sliding seat that is in interference fit with the T-shaped sliding groove, and the T-shaped sliding seat has a metal body that contacts the pressing plate seat. Through the matching structure of the T-shaped sliding groove and the T-shaped sliding seat, the detachable connection between the pressing plate and the pressing plate seat is realized, so that different pressing plates can be replaced according to different test samples.

[0011] One end of the pressing plate seat is provided with an operating handle.

[0012] The operating handle is of an L-shaped structure and is in the same plane as the pressing plate seat.

[0013] Through the setting of the operating handle, the lifting operation of the pressing plate mechanism is facilitated. By adopting the L-shaped structure in the same plane as the pressing plate seat, the scraping and collision during the movement are avoided, and the structure is more reasonable.

[0014] The utility model has a simple structure, strong practicability and good use effect, and is worthy of wide promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS
