The present invention relates to the technical field of cloth detection, and in particular to an automatic cloth performance detection machine.

Background Art

The fabric tensile tester is an instrument specially used to measure the tensile strength and elongation of textiles and fabrics. It evaluates the mechanical properties of fabrics by simulating the tensile force that fabrics are subjected to in actual use.

When using a fabric tensile tester to test the tensile strength of fabric, since the existing fabric tensile tester uses manual loading, the two ends of the fabric need to be fixed on the clamps respectively. When the fabric is fixed, the fabric is prone to shifting, resulting in inconsistent tightness of the two long sides of the clamped fabric. The existing fabric tensile tester cannot correct the shifted fabric, resulting in uneven force when the fabric is subjected to pulling force. Since the tighter clamped side of the fabric does not have a larger tensile deformation space than the looser side, the fabric is prone to tearing from the tighter clamped side, which in turn reduces the accuracy of the fabric tensile strength test value.

A plurality of calibration lines 20201 are provided on the upper side of the support plate 202 .

Furthermore, in order to prevent the edges of the correction plate 2 and the supporting plate 202 from wearing the fabric, the left and right sides of the correction plate 2 are both configured as curved surfaces; the left and right sides of the supporting plate 202 are both configured as curved surfaces.

It also includes a frosting plate 4; the frosting plate 4 is fixedly connected to the lower side of the correction plate 2; and a smooth layer 20202 is arranged on the upper side of the supporting plate 202.

The present invention corrects the deviated fabric by means of the correction plate 2, thereby solving the problem that the fabric is deviated after being fixed due to manual feeding, so that the two long sides of the clamped fabric have inconsistent tightness, resulting in uneven force when the fabric is subjected to pulling force, and further reducing the accuracy of the fabric tensile force detection value. The specific working is as follows:

When testing the tension of the fabric, the staff first puts the fabric between the lower clamp 103 and the upper clamp 104. The angle formed by the front side of the lower clamp 103 and the front side of the upper clamp 104 makes it easy to put the fabric between the lower clamp 103 and the upper clamp 104, thereby realizing convenient loading of the fabric. After the fabric is placed, the second driving member 201 is controlled to drive the supporting plate 202 to rise, so that the supporting plate 202 supports the middle part of the fabric. After the supporting plate 202 contacts the fabric, the staff aligns the long side of the fabric with the calibration line 20201 on the upper side of the supporting plate 202, which is conducive to the preliminary correction of the offset fabric. Subsequently, the third driving member 203 is controlled to drive the fixing plate 204 and the DD motor 205 to descend, thereby driving the correction plate 2 and the camera 3 to descend together. In this process, the camera 3 is used to 3 Monitor the fabric that is offset on the supporting plate 202, determine the offset degree of the fabric on the supporting plate 202, and transmit the monitored data back to the detection platform 1, so that the detection platform 1 controls the DD motor 205 to drive the correction plate 2 to rotate, so that the correction plate 2 rotates to be consistent with the offset state of the fabric. As the third driving member 203 drives the correction plate 2 to continue to descend, the rotated correction plate 2 drives the frosting plate 4 to press to the upper side of the fabric, and then controls the DD motor 205 to drive the correction plate 2 to rotate and reset, so that the correction plate 2 drives the offset fabric on the supporting plate 202 to move, and grinds the offset fabric to a state flush with the calibration line 20201, and corrects the offset fabric. When the tensile strength test of the fabric is performed, the uneven force caused by the offset of the fabric is prevented, thereby improving the accuracy of the fabric tensile strength test value.

When the correction plate 2 drives the offset fabric on the supporting plate 202 to move, the friction between the correction plate 2 and the fabric is increased by the frosting plate 4, and the friction between the supporting plate 202 and the fabric is reduced by the smooth layer 20202, so that the correction plate 2 drives the offset fabric to move on the supporting plate 202, and prevents the fabric from slipping between the correction plate 2 and the correction plate 2 when moving, thereby enhancing the correction effect of the correction plate 2 on the offset fabric. When the fabric is moved by the correction plate 2, the left and right sides of the correction plate 2 are provided with curved surfaces, and the left and right sides of the supporting plate 202 are provided with curved surfaces, so as to prevent the fabric from contacting with the edges of the correction plate 2 and the supporting plate 202, thereby avoiding pinch marks on the fabric surface, and at the same time, preventing the edges of the correction plate 2 from wearing the fabric when it rotates, thereby avoiding affecting the subsequent fabric tensile test and ensuring the accuracy of the fabric tensile test value.

When the staff places the cloth, the two ends of the cloth to be clamped are placed on the upper side of the pad 302. When the correction plate 2 rotates to align the cloth, the correction plate 2 drives the pressing plate 303 to rotate together. When the correction plate 2 descends to press the cloth, the correction plate 2 drives the pressing plate 303 to descend together, and presses the pressing plate 303 onto the cloth on the upper side of the pad 302 to clamp and fix the two ends of the cloth. In this process, the cloth is clamped into the recess 30201 by the protrusion 30301, which is conducive to strengthening the alignment. The fixing effect of the two ends of the cloth, when the correction plate 2 drives the offset cloth on the supporting plate 202 to move and correct, the correction plate 2 drives the pressing plate 303 to rotate together, so that the pressing plate 303 drives the pad 302 to slide in the sliding groove 30101, and drives the two ends of the cloth to rotate with the middle part of the cloth for correction, preventing the cloth outside the correction plate 2 from wrinkling due to inability to rotate with the middle part of the cloth, and avoiding the subsequent pulling of the cloth, so as to avoid the clamping position of the cloth from wrinkling and affecting the accuracy of the cloth tensile force detection value.

When the cloth is corrected, the first driving member 108 is controlled to drive the upper clamp 104 to descend to fit with the lower clamp 103 to clamp and fix the cloth, and then the second driving member 201 is controlled to drive the supporting plate 202 to descend and reset, and at the same time the third driving member 203 is controlled to drive the correction plate 2 to rise and reset, so as to release the fixation on the middle part of the cloth and prepare for the next inspection to correct the cloth, and then the two electric sliders 102 are controlled to drive the corresponding lower clamp 103 and upper clamp 104 to move away from each other on the slide rail 101 to pull the cloth. When the cloth is pulled and broken, the maximum pulling force on the cloth when it breaks is tested by the testing platform 1. , in order to judge the tensile strength performance of the fabric, when pulling the fabric, the lower pad 105 and the upper pad 106 are in contact with the fabric, and a buffer layer can be formed between the fabric and the hard contact surface of the upper clamp 104 and the lower clamp 103, so that the clamping originally concentrated on the edge of the fabric should be dispersed to a larger area, which is conducive to dispersing the clamping force generated by the upper clamp 104 and the lower clamp 103 when clamping the fabric, reducing the stress generated by the upper clamp 104 and the lower clamp 103 when clamping the fabric, preventing the fabric from being torn at the clamped position due to the high stress generated by clamping, and avoiding the influence of stress interference on the accuracy of the fabric tensile strength detection value.

Example 2

On the basis of Example 1, as shown in Figures 2 and 4-6, an adjustment system is also included, which includes a clamping block 401, an elastic member 402, a connecting rope 403 and a rope winding rod 404; each upper clamp 104 is provided with a through slot 10401; each through slot 10401 is slidably connected with a plurality of clamping blocks 401; an elastic member 402 is fixedly connected between each two adjacent clamping blocks 401, and the elastic member 402 is a spring; each upper clamp 104 is movably connected with a connecting rope 403; each connecting rope 403 passes through the corresponding clamping block 401; and each upper clamp 104 is fixedly connected with two rope winding rods 404.

When the cloth is corrected, when the lower clamp 103 and the upper clamp 104 clamp the cloth, the interval between the upper clamp 104 and the lower clamp 103 is controlled to make the cloth in a relaxed state between the upper clamp 104 and the lower clamp 103. Then the staff pulls the connecting rope 403 to drive the clamp block 401 to slide in the through groove 10401, and gathers a plurality of dispersed clamp blocks 401 to the front of the upper clamp 104, and compresses the elastic member 402 at the same time. When the clamp block 401 is gathered to the front of the upper clamp 104, the clamp block 401 drives the upper side of the cloth to gather to the front of the upper clamp 104, so that the flat cloth is wrinkled. After the cloth is wrinkled, the staff will wind the pulled connecting rope 403 around the rope winding rod 404 to fix it, so that the cloth remains in a wrinkled state for subsequent pulling work, which is used to simulate the wrinkles generated when the cloth is pulled, which is beneficial to simulate the deformation and wrinkles of the cloth when it is actually pulled, thereby improving the authenticity of the cloth tensile resistance performance test and enhancing the reference value of the detected cloth tensile resistance value. After the cloth testing is completed, the staff will loosen the connecting rope 403 on the rope winding rod 404, so that the clamping block 401 is reset by the elastic force of the elastic member 402, and prepare for the next tensile resistance performance test of the cloth.
