Description

Technical Field

[0001] The utility model relates to the field of clothing production, in particular to a fabric resilience testing device. Background Art

[0002] Nowadays, with the improvement of living standards, people are also pursuing higher quality in clothing, especially suit pants, which are not only required to have a straight and smooth appearance (but this greatly reduces comfort). Therefore, on the basis of rigid and straight fabrics, elastic fabrics are added for blending, so that they can be elastic and not restrictive when worn. Especially when squatting, sitting, etc., the knees are in a bent state, and the pants are also bent. The knees are subjected to bending force. If the fabric has poor resilience, wrinkles will appear at the knees when standing, which greatly reduces the overall beauty of the pants.

[0059] a slide bar 61 disposed on the swing member 4;

[0060] The upper fixing seat 62 is slidably connected to the slide rod 61 . The upper fixing seat 62 can slide up and down relative to the support seat 3 to limit the upper end of the fabric installation sleeve 5 .

[0061] During actual assembly:

[0062] (1) Assemble the transmission assembly 22, which includes a driving wheel 221, a driven wheel 222, an output shaft 224 and a transmission belt 223; the driving wheel 221 is arranged at the output end 211 of the motor 21; the driven wheel 222 is mounted on the output shaft 224; the output shaft 224 is also equipped with two first cams 25 and second cams 26 with opposite installation directions, and the end of the output shaft 224 facing away from the driven wheel 222 is inserted into the connecting member 225; the driving wheel 221 and the driven wheel 222 are connected by the transmission belt 223, so that the motor 21 drives the first cam 25 and the second cam 26 on the output shaft 224 to rotate;

[0063] (2) Assemble the drive mechanism 2. First, install one end of the first pendulum rod 231 and the third pendulum rod 241 on the connecting rod 271 of the mounting frame 27 below the workbench 1. Then, hinge the other ends of the first pendulum rod 231 and the third pendulum rod 241 to the second pendulum rod 232 and the fourth pendulum rod 242 respectively, and make the second pendulum rod 232 and the fourth pendulum rod 242 pass through the workbench 1. Finally, adjust the distance between the connecting rod 271 and the output shaft 224 so that the first cam 25 and the second cam 26 can abut against the first pendulum rod 231 and the third pendulum rod 241 when they rotate, and fix the motor 21 and the connecting member 225 in the transmission assembly 22 below the workbench 1 by the fixing screw 28.

[0064] (3) Install the support base 3, which is provided with an assembly base 8 arranged perpendicularly thereto; the assembly base 8 is provided with a plurality of assembly holes 81; fix the support base 3 to the workbench 1; then assemble the mating member 9 to any assembly hole 81 through the stopper 10; and then install the lower fixing base 7 on the support base 3;

[0065] (4) Install two swing members 4, each of which is provided with a slide rod 61 and an upper fixed seat 62, and a sliding track 41 extends from one side of the swing member 4; each side of the two sliding tracks 41 is provided with a slider 13; hinge the two swing members 4 to the support seat 3 respectively, and then connect the two sliders 13 to the second swing rod 232 and the fourth swing rod 242 respectively;

[0066] When using:

[0067] The fabric to be tested 11 is mounted on the sleeve 12, and then the sleeve 12 is mounted on the fabric installation sleeve 5. The positions of the fitting 9 and the upper fixing seat 62 are adjusted according to the size of the fabric installation sleeve 5, so that the upper fixing seat 62, the lower fixing seat 7, the fitting 9 and the limiting member 10 clamp and limit the fabric installation sleeve 5 (see Figure 5 ).

[0068] The motor 21 is started, driving the driving wheel 221 to start rotating, and the driven wheel 222 starts to rotate under the action of the transmission belt 223, so that the first cam 25 and the second cam 26 on the output shaft 224 start to rotate. When the first cam 25 rotates until its convex portion 251 abuts against the first swing rod 231, the first swing rod assembly 23 is gradually pushed upward by the first cam 25, thereby driving the slider 13 to slide away from the swing member 4, and driving the swing member 4 to swing relative to the support seat 3, so that the upper assembly part 51a of the fabric installation sleeve 5 is squeezed and bent relative to the lower assembly part 51b; until the first cam 25 rotates to the point where its convex portion 251 is closest to the connecting rod 271, at this time, the two assembly parts 51 are bent to the maximum angle (see Figure 6 ); then, the first cam 25 continues to rotate, and its protrusion 251 gradually separates from the outer arc surface 2311 of the first rocking rod 231, causing the effect of the first cam 25 on the first rocking rod assembly 23 to gradually decrease. The second rocking rod 232 falls downward under the action of gravity, causing the slider 13 to slide toward the side of the swinging member 4, and driving the swinging member 4 to return to its original position, causing the upper assembly 51a to return to its original position; since the first cam 25 and the second cam 26 are installed in opposite directions, the first cam 25 and the second cam 26 act alternately on the first rocking rod assembly 23 and the second rocking rod 232 assembly, respectively, causing the two rocking members 4 to swing in an alternating manner.

[0069] The utility model provides a fabric rebound elasticity testing device, which is easy to use and maintain, and meets the needs of manufacturers for fabric rebound elasticity testing; the fabric to be tested is installed on the installation sleeve, and the upper and lower ends of the fabric installation sleeve are limited by the upper fixing seat, the lower fixing seat, the matching piece and the limiting piece, and the driving mechanism drives the swinging piece to swing back and forth relative to the support seat; during the swinging of the swinging piece, the upper assembly part of the fabric installation sleeve is squeezed and bent relative to the lower assembly part, thereby simulating the stress condition of the fabric when the knee is in a bent state or when actually walking; then, the swinging piece slowly resets, and the fabric installation sleeve also gradually resets. At this time, the rebound of the surface and whether wrinkles are generated can be directly observed, thereby making the test results more accurate; and the spacing between the upper fixing seat, the lower fixing seat and the matching piece can be adjusted according to the different volumes of fabric installation sleeves, meeting the testing needs of fabrics of different types and thicknesses, thereby expanding the scope of use of the equipment. The present invention is provided with two sets of rocker assemblies and cams, and the first cam and the second cam are installed in opposite directions, so that the two fabric installation sleeves can form a spatial staggered swing under the drive mechanism, and can simultaneously test the two sets of installation sleeves, thereby improving the efficiency of experimental testing;
