AI Technical Summary
When testing the strength of knitted fabric, the sharp edges of the clamping mechanism come into contact with the knitted fabric, which reduces the accuracy of the test and makes it easy to break at the clamping point.
The design employs an arc-shaped groove and circumferential limiting components. The arc-shaped groove transitions with the arc-shaped surface of the fixed roller, reducing the impact of sharp edges on the knitted fabric. The circumferential limiting components restrict the circumferential freedom of the fixed roller, ensuring that the knitted fabric is fixed after being wrapped around the fixed roller three to four times.
This improves the accuracy of strength testing for knitted fabrics, avoids breakage caused by sharp edges, and ensures the accuracy of test results.

[0035] Two winding parts 2 are oppositely arranged on the flat base 1, and the winding part 2 is used to wind and fix the end of the knitted fabric.
[0036] The winding part 2 includes two support seats 21 oppositely arranged on the top of the flat base 1, and one of the support seats 21 is fixedly arranged on the flat base 1.
[0037] Two horizontal supporting arms 22 are oppositely arranged on the support seat 21.
[0038] A fixed roller 23 is rotatably arranged between the two horizontal supporting arms 22.
[0039] A fixing part 24 is arranged on the fixed roller 23, and the fixing part 24 is used to clamp and fix the end of the knitted fabric.
[0040] A circumferential limiting part 25 is arranged between the one horizontal supporting arm 22 and the end face of the fixed roller 23, and the circumferential limiting part 25 is used to limit the rotation of the fixed roller 23.
[0041] The two ends of the knitted fabric are fixed on the two fixed rollers 23 through the two fixing members 24, so that the knitted fabric can be wound on the fixed rollers 23 for at least three turns until the knitted fabric between the two fixed rollers 23 is in a straightened state, thereby improving the fixing effect of the knitted fabric. After the knitted fabric is fixed, the fixed rollers 23 are fixed by using the circumferential limiting member 25 to constrain the circumferential degree of freedom of the fixed rollers 23, so that the fixing operation of the knitted fabric is completed. In this way, the circumferential rolling of the fixed rollers 23 during the tensile strength detection can be avoided, and the accuracy of the tensile strength detection result of the knitted fabric can be affected.
[0042] As shown in Figure 1 and Figure 2 , the strength detection mechanism of the knitted fabric further comprises:
[0043] The telescopic cylinder 4 is fixed on the flat base 1, and the telescopic cylinder 4 is used to drive the two support seats 21 to move closer to or away from each other.
[0044] The tension meter 3 is fixed between the output end of the telescopic cylinder 4 and the remaining one support seat 21, and the tension meter 3 is used to detect the tension value of the telescopic cylinder 4 pulling the support seat 21 to move.
[0045] After the fixing operation of the knitted fabric is completed, the telescopic cylinder 4 is controlled to retract and pull the tension meter 3 and the movable support seat 21 to move synchronously in a straight line, so that the movable support seat 21 moves away from the fixed support seat 21 until the knitted fabric is pulled to break. The tension meter 3 will record the limit tension value at the moment when the knitted fabric breaks, so as to collect more accurate related detection experimental data.
[0046] As shown in Figure 3 and Figure 4 , the fixing member 24 comprises an insertion rod 242 inserted with the insertion slot 241 arranged axially on the outside of the fixed roller 23, a straight insertion slot 243 is arranged between the two end faces of the insertion rod 242, and an arc-shaped insertion slot 244 is arranged between the outside of the insertion rod 242 and the straight insertion slot 243.
[0047] The inner wall of the arc-shaped insertion slot 244 connecting with the arc surface of the fixed roller 23 is a first arc surface, and the inner wall of the arc-shaped insertion slot 244 connecting with the inside of the straight insertion slot 243 is a second arc surface.

The arc-shaped insertion slot 244 and the straight insertion slot 243 form a U-shaped cloth clamping groove, and the inner wall of the arc-shaped insertion slot 244 and the outside of the fixed roller 23 are smoothly connected. The knitted fabric can be prevented from breaking near the fixed roller 23 due to uneven stress, and the influence of the edge on the tensile strength detection result of the knitted fabric is greatly weakened.
[0049] In the knitting cloth end fixed, first knitting cloth end along the fixed roller 23 from the axis of the U-shaped card cloth one end into and wear to the U-shaped card cloth the other end, in the knitting cloth width is less than the axis of the U-shaped card cloth length, so that the knitting cloth end in the U-shaped card cloth in the middle, then the plug rod 242 is inserted into the slot 241 outside the fixed roller 23, until the end surface of the plug rod 242 with the end surface of the fixed roller 23 flush, then clockwise and counterclockwise rotation of two fixed roller 23, until the knitting cloth between the two fixed roller 23 is in the straightened state, that is, the initial fixation of the knitting cloth can be completed.
[0050] As shown in Figure 3 and Figure 5 The circumferential limiting piece 25 includes the shaft end disc 251 fixed to one of the shaft end surfaces of the fixed roller 23, and the shaft end disc 251 is provided with a through hole 252. One of the horizontal support arms 22 is provided with an insertion hole 254, and the insertion hole 254 and the through hole 252 are provided with an insertion block 253 therebetween.
[0051] The insertion hole 254 is located on the horizontal support arm 22 close to the shaft end disc 251, and the insertion hole 254 and the through hole 252 correspond to each other.

[0053] After the initial fixation of the knitting cloth is completed, the two fixed rollers 23 are rotated counterclockwise and clockwise respectively by rotating them simultaneously. Under the premise of keeping the knitting cloth straight, the positions of the through hole 252 and the insertion hole 254 are adjusted circumferentially so that they are coaxial. Then the two ends of the insertion block 253 are inserted into the through hole 252 and the insertion hole 254 respectively, and the entire fixation of the knitting cloth is completed. In this way, the freedom of the circumferential direction of the fixed roller 23 is limited, and the fixed roller 23 is prevented from rotating circumferentially during the strength detection of the knitting cloth, so as to avoid affecting the accuracy of the detection data.
[0054] As shown in Figure 2 and Figure 3 The strength detection mechanism of the knitting cloth further includes a guide 5 provided on the top of the flat base 1, which is used to limit and guide the linear movement of one of the support seats 21.
