Description

Technical Field

[0001] The invention relates to the technical field of fabric performance testing, in particular to a fabric wear resistance testing mechanism. Background Art

[0002] The wear resistance of textiles refers to the wear resistance of the fabric surface under wear conditions, that is, the ability of the fabric to maintain its original performance and appearance when subjected to local or comprehensive friction, wear, etc.; wear resistance is one of the important indicators of textile quality and directly affects the service life and performance of textiles; therefore, it is very important to test and evaluate the wear resistance of textiles.

[0003] The Chinese patent application with publication number CN115096732A discloses a fabric wear resistance testing mechanism, which solves the problem that the existing testing mechanism cannot change the test temperature to detect the wear resistance of the fabric at different temperatures. However, the above patent still has the following shortcomings: (1) When testing the wear resistance of fabrics, the friction area will heat up quickly due to repeated friction in a local area. The heating may cause thermal shrinkage of the fabric. Many fabrics will shrink after being heated. This is because the internal structural adjustment of the fiber causes changes in the fiber length and diameter. For example, when the temperature of wool fabrics rises, the scale layers of the wool fibers will interact with each other, causing the fibers to shrink. This size change will change the force applied to the fabric during the friction process. The originally flat surface of the fabric may have wrinkles. During friction, the force at the wrinkles will be concentrated, increasing the possibility of local wear, thereby reducing the accuracy of the wear resistance test. (2) During friction, a small amount of fabric fibers will fall off. If they are not cleaned up in time, the fallen fibers will accumulate on the fabric surface, increasing the roughness of the fabric surface. In subsequent friction tests, the friction coefficient between the friction head and the fabric will change, affecting the test results: In this regard, we proposed a fabric wear resistance testing mechanism to solve the above problems.

[0013] The present invention provides a fabric wear resistance testing mechanism.

[0022] Four support columns 12 are fixed to the bottom of the test body 1, and a control button 13 is set on one side of the test body 1.

The pressure testing pen 47 is electrically connected to an external pressure tester. The pressure testing pen 47 transmits the pressure data of the fabric to the pressure tester. When scratches appear on the fabric, the pressure of the pressure testing pen 47 at this time can be recorded. A vertical groove 48 is opened on one side of the rotating plate 42, and a block 49 is slidably connected to the inner surface of the vertical groove 48.

A folding rod 105 is fixed on one side of the ring frame 102, and the top of the folding rod 105 is fixed to the bottom of the test bench 2.

[0028] By setting the reciprocating drive mechanism 10, the fabric can be moved back and forth quickly and automatically, and the wear resistance test can be achieved by cooperating with the downward pressure contact of the pressure test pen 47.

[0029] A clamping assembly 11 for clamping and fixing the fabric is arranged on the top of the test bench 2. The clamping assembly 11 includes four clamping blocks 111 arranged on the top of the test bench 2. The tops of the four clamping blocks 111 are all penetrated with transverse grooves 112. Four screw holes 113 are arranged on the top of the test bench 2. The inner surfaces of the four screw holes 113 are all threadedly connected with screws 114. The four screws 114 fix the clamping blocks 111 on the test bench 2.

[0030] By setting the pressing assembly 11, the fabric can be quickly limited and fixed, which prevents the fabric from moving during friction and increases stability.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] During operation, place the cut small square fabric in the center of the top of the test bench 2, rotate the four screws 114, move the four pressure blocks 111, so that the four pressure blocks 111 press the fabric, and then tighten the screws 114 to fix the fabric, and further start the motor 4 106 to make the motor 4 106 drive the missing gear 104 to rotate, and then drive the annular frame 102, the folding rod 105, and the test bench 2 to move back and forth left and right, and then start the electric telescopic rod 31, so that the electric telescopic rod 31 drives the pressure test pen 47 to move downward, so that the bottom end of the pressure test pen 47 contacts and squeezes the fabric, and the pressure test pen 47 is rubbed on the fabric by the left and right reciprocating movement of the fabric, and the pressure friction force is gradually increased by moving the electric telescopic rod 31 downward, and then the friction of the fabric is observed. When obvious wear marks appear on the fabric, the pressure value at this time is recorded. By starting motor 1 37, motor 1 drives the circular frame 36 to rotate, and then drives the pressure test pen 47 to perform circular motion on the fabric, and cooperates with the left and right reciprocating movement of the fabric, so that the pressure test pen 47 performs spiral friction movement on the fabric, and starts motor 2 55, so that motor 2 drives the screw rod 54 to rotate, and then drives the slide 53 to move, and then adjusts the size of the circular motion radius of the pressure test pen 47, thereby realizing a large-area friction test on the fabric, avoiding repeated friction in a local area, which causes the fabric to heat up quickly, and starts motor 3 45 to rotate one circle, so that motor 3 45 drives the full gear 44 and the half gear 43 to rotate, and the full gear 44 rotates one circle to drive the half gear 43 to rotate half a circle, and then drives the rotating plate 42 to flip 180 degrees, so that the adhesion roller 413 moves downward to contact the fabric to decompress, so that the adhesion roller sticks to the fiber.

[0033] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
