Description

Technical Field

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

[0002] Non-woven fabric is a material made of directional or randomly arranged fibers through physical methods such as friction, adhesion, bonding, etc. It does not form fabric through traditional weaving or knitting processes. The strength test of non-woven fabric is a way to test the performance of non-woven fabric. In the strength test of non-woven fabric, it is necessary to use a clamp to clamp and limit it.

[0003] However, it still has the following disadvantages in actual use:

[0004] The existing non-woven fabric testing fixture acts on the non-woven fabric through the clamping blocks that move up and down to achieve the purpose of clamping the non-woven fabric. However, when clamping the non-woven fabric in multiple positions, the upper and lower clamping blocks need to be opened. If the opening is large, the operation will take a long time and waste electricity. If the opening is small, it is easy to contact with the clamping blocks, causing surface wear. Utility Model Content

[0005] The purpose of the utility model is to provide a non-woven fabric strength testing fixture to solve the problem raised in the above-mentioned background technology. The existing non-woven fabric testing fixture acts on the non-woven fabric through the clamping blocks that move up and down to achieve the purpose of clamping the non-woven fabric. However, when clamping the non-woven fabric in multiple positions, the clamping blocks arranged up and down need to be opened. If the opening is large, it will take a long time during the operation and waste electricity. If the opening is small, it is easy to contact with the clamping blocks, causing surface wear.

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

[0007] The utility model is a non-woven fabric strength testing fixture, comprising:

[0008] A supporting component, the supporting component comprising a supporting seat;

[0009] A connecting component, the connecting component comprising a connecting rod clamped on the outer side of the upper end of the support seat;

[0010] A test clamping component, the test clamping component comprising an upper clamping plate, a lower clamping plate, a bracket and a clamping wheel;

[0011] The upper clamping plate is fixed to the inner upper part of the connecting rod, and the lower clamping plate is arranged directly below the upper clamping plate, the bracket equidistantly penetrates the inner side of the lower clamping plate, and the clamping wheel rotates in the upper middle section of the bracket;

[0012] The non-woven fabric is arranged between the upper clamping plate and the inner side of the lower clamping plate.

[0013] Furthermore, screw holes are equidistantly formed on the inner side of the lower clamping plate, and threads equidistantly arranged on the lower part of the outer surface of the bracket extend into the screw holes.

[0014] Furthermore, an opening is formed through the middle section of the lower outer side of the connecting rod, and a protrusion fixed at the middle part of the outer side of the lower clamping plate extends out of the opening.

[0015] Furthermore, an electric push rod is fixed to the lower portion of the outer side of the connecting rod, and the upper portion of the output end of the electric push rod is fixed to the lower end of the protrusion.

[0016] Furthermore, the support component also includes an axle seat and a moving wheel;

[0017] The shaft seat is fixed to the four corners of the lower end of the support seat, and the moving wheel is sleeved on the middle part of the lower end of the shaft seat.

[0018] Furthermore, the connecting component also includes a card block;

[0019] The clamping block is fixed to the lower end of the connecting rod, and the lower end of the clamping block is clamped in a clamping groove provided on the outer side of the upper end of the supporting seat.

[0020] Furthermore, it also includes a receiving component;

[0025] The utility model is provided with a bracket and a clamping wheel. When the non-woven fabric is clamped for strength testing, if the position of the non-woven fabric is moved, the force required for the lower range movement can be applied to the lower clamping plate through a controlled electric push rod. When the non-woven fabric is moved, a plurality of clamping wheels are in contact with the non-woven fabric, and the rolling method can meet the movement requirements of the non-woven fabric. There is no need to move the lower clamping plate downward over a large range, thus saving power costs.
