Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic type fabric bursting instrument, in particular to a non-woven fabric bursting test device. Background Art

[0002] The non-woven fabric bursting test device is a device used to test the bursting strength and performance of non-woven fabric materials. It is mainly composed of an air pressure system and a test fixture. The bursting test is performed to determine the durability of non-woven fabrics in actual use.

[0003] The non-woven fabric bursting test device in the prior art is, during the test, to place the non-woven fabric sample on top of the rubber tympanic membrane, and then move the squeezing cup located above the non-woven fabric downward so that the non-woven fabric is clamped between two circular clamps, and finally, pressure is applied by increasing the air pressure on the rubber tympanic membrane to make the rubber tympanic membrane swell and become larger. When the air pressure exceeds the bursting strength of the non-woven fabric, the non-woven fabric will burst, and the bursting data will be recorded on the display, thereby completing the non-woven fabric bursting test.

[0004] However, the existing non-woven fabric bursting test device usually tests relatively thin non-woven fabrics. When testing multi-layer and relatively thick non-woven fabrics, it is necessary to increase the pressure of the rubber tympanic membrane. Since the extrusion cup is made of a relatively hard plastic material, when the pressure of the rubber tympanic membrane increases, the non-woven fabric clamped by the edge of the extrusion cup will slip, resulting in the strength of the test result being greater than the actual strength, thereby affecting the accuracy of the non-woven fabric bursting test. Therefore, there are deficiencies. Therefore, a non-woven fabric bursting test device with an improved structure is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a non-woven fabric bursting test device, which is used to solve the problem that when the existing non-woven fabric bursting test device performs a bursting test on multi-layer and thick non-woven fabrics, the non-woven fabric clamped by the edge of the extrusion cup slips, resulting in the strength of the test result being greater than the actual strength.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A non-woven fabric bursting test device comprises an extrusion seat and an extrusion cup respectively arranged at the bottom and top of an inner wall of a machine body, a non-woven fabric is clamped between the extrusion seat and the extrusion cup, clamping grooves opened toward the extrusion cups are symmetrically arranged at positions near both sides of the bottom of the inner wall of the machine body, a screw rod is vertically penetrated at the center position of the top of the clamping groove, one end of the screw rod is located inside the clamping groove and is rotatably connected to a squeezing plate, and the non-woven fabric is fixedly clamped between the bottom of the extrusion plate and the bottom of the inner wall of the clamping groove.

[0008] Preferably, a hand crank is fixedly connected to the top end of the screw rod.

[0009] Preferably, anti-slip pads are provided at the bottom of the extrusion plate and the bottom of the inner wall of the clamping groove.

[0010] Preferably, slide grooves are symmetrically arranged at positions near both sides of the top of the inner wall of the machine body, and the bottom of the slide grooves is movably connected with a transparent baffle located between the top and bottom of the inner wall of the machine body, and two sides of the transparent baffle are provided with flat handles.

[0011] Preferably, the bottoms of the inner walls of the two groups of clamping grooves and the top of the extrusion seat are located on the same water surface line.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides a clamping groove and a squeezing plate, and drives the squeezing plate to squeeze and fix the two sides of the non-woven fabric and press the squeezing cup downward to fix the non-woven fabric by rotating the screw rod, so that the non-woven fabric is fixed more firmly, and the non-woven fabric squeezed by the edge of the squeezing cup due to excessive pressure of the rubber tympanic membrane is prevented from slipping, thereby avoiding the error that the strength of the non-woven fabric test result is greater than the actual strength, and solves the problem that when the existing non-woven fabric bursting test device performs a bursting test on multi-layer and thick non-woven fabrics, the non-woven fabric clamped by the edge of the squeezing cup slips, resulting in the strength of the test result being greater than the actual strength.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a non-woven fabric bursting test device, comprising an extrusion seat 101 and an extrusion cup 102 respectively arranged at the bottom and top of the inner wall of a body 1, a non-woven fabric 2 is clamped between the extrusion seat 101 and the extrusion cup 102, and clamping grooves 3 opened toward the extrusion cup 102 are symmetrically arranged at positions near both sides of the bottom of the inner wall of the body 1, and the bottoms of the inner walls of the two groups of clamping grooves 3 are located on the same water surface line as the top of the extrusion seat 101, so that the clamped non-woven fabric 2 is straighter, thereby improving the accuracy of the test.

[0020] A screw rod 4 is vertically penetrated at the center position of the top of the clamping groove 3, and a hand crank handle 401 is fixedly connected to the top of the screw rod 4 to facilitate the operator to rotate the screw rod 4. One end of the screw rod 4 located inside the clamping groove 3 is rotatably connected to an extrusion plate 5, and an anti-slip pad 6 is provided at the bottom of the extrusion plate 5 and the bottom of the inner wall of the clamping groove 3 to increase the friction force of clamping the non-woven fabric 2 and prevent slipping.

[0021] The non-woven fabric 2 is fixedly clamped between the bottom of the extrusion plate 5 and the bottom of the inner wall of the clamping groove 3. Slide grooves 7 are symmetrically arranged at the positions near the two sides of the top of the inner wall of the body 1. The bottom of the slide groove 7 is movably connected with a transparent baffle 8 located between the top and the bottom of the inner wall of the body 1 to protect the tester and improve his safety. A flat handle 801 is arranged on both sides of the transparent baffle 8.

[0022] Working principle: Place the non-woven fabric 2 to be tested on the top of the extrusion seat 101, put the two sides of the non-woven fabric 2 into the clamping groove 3 respectively, turn the screw 4 to make the extrusion plate 5 squeeze and fix one side of the non-woven fabric 2, straighten the other end of the non-woven fabric 2, and fix and clamp it through another group of clamping grooves 3, squeeze the extrusion cup 102 downward to clamp it, and the rubber tympanic membrane inside the extrusion seat 101 performs a bursting test on the non-woven fabric 2. The above settings make the non-woven fabric 2 more firmly fixed, avoid the non-woven fabric 2 at the inner edge of the extrusion cup 102 during the bursting test, and improve the accuracy of the bursting test of the non-woven fabric 2.
