[0032] Specifically, in order to solve the technical problems of cloth conveying before clamping both ends, whether the stress of each section of cloth is uniform during cloth tension detection, and whether the cloth is smooth as a whole in the tensioning state during the process of detecting the cloth tearing property and tension, the utility model moves one end of the cloth to be detected from one end of the tensioning assembly 2 to the other end through the pinch mechanism 3, clamps both ends of the cloth through the clamping assembly 1 at both ends of the tensioning assembly 2, makes each tensioning rod 21 of the tensioning assembly 2 close to the cloth through the pre-tightening mechanism 4, and realizes that the cloth presents a wave shape between each tensioning rod 21, completes the pre-tensioning of the cloth, then drives each tensioning rod 21 and the clamping assembly 1 to move to both sides to stretch the cloth through the translation mechanism 22, and detects and collects the tension data of the cloth through the sensors on each tensioning rod 21 and the clamping assembly 1. The utility model divides the cloth into multiple sections by using multiple tensioning rods 21, detects the tension of each tensioning section during the tensioning process, ensures the uniform stress of each section of cloth, effectively guarantees the smoothness of the cloth through the pre-tightening mechanism 4, and is more conducive to the accuracy and authenticity of the cloth tearing property and tension detection.

[0033] As shown in Figures 2 to 7 The following preferred technical solutions are provided:

[0034] The translation mechanism 22 includes a guide rod group 221, an equidistant transmission rod 222 and a drive wheel group 223, the guide rod group 221, the equidistant transmission rod 222 and the drive wheel group 223 are all fixedly installed above the workbench 5 through a mounting frame 224, the guide rod group 221 is located below the equidistant transmission rod 222 and is in sliding connection with the equidistant transmission rod 222, the drive wheel group 223 is in transmission connection with the equidistant transmission rod 222, each tensioning rod 21 is in sliding connection with the guide rod group 221 through a rod frame 225, the rod frame 225 is in sliding connection between the equidistant transmission rod 222, equidistant helical grooves 226 are symmetrically arranged on the equidistant transmission rod 222, the helical directions of the equidistant helical grooves 226 at both ends of the equidistant transmission rod 222 are opposite, and each rod frame 225 is in sliding connection with the corresponding equidistant helical groove 226 through a connecting head 227.

[0035] The plurality of rod holders 225 are arranged along the length direction of the guide rod set 221, and the rod holders 225 at both ends are fixedly connected with a clamping assembly 1 respectively, and only the odd-numbered or only the even-numbered rod holders 225 are slidably connected with the corresponding tension rods 21 through sliding grooves 228 provided on the corresponding rod holders 225, and the upper end of the tension rod 21 slidably connected with the rod holder 225 is provided with a sliding guide rod 229, and the sliding guide rod 229 is connected with the corresponding rod holder 225 through a spring 220.

[0036] Specifically, in order to solve the technical problem of applying stable tension to the cloth and ensuring that the tension of each section of the cloth is uniformly stressed, the equidistant transmission rod 222 is driven to rotate by the driving wheel set 223, the equidistant screw groove 226 on the equidistant transmission rod 222 cooperates with the connecting head 227 on each rod holder 225, so that when the rod holder 225 moves towards the two ends of the guide rod set 221 after the cloth is clamped by the clamping assemblies 1 at both ends, the cloth is stretched between the tension rods 21, and the tension of the cloth is detected by the sensors at the corresponding positions of the tension rods 21.

[0037] During the entire detection process, the position state of the rod holder 225 and the tension rod 21 is divided into three states, the first state is the cloth clamping and conveying state, that is, the initial state: first, during the cloth clamping and conveying process, the cloth is clamped and conveyed from the clamping assembly 1 at one end to the clamping assembly 1 at the other end by the clamping and conveying mechanism 3, at this time, the tension rod 21 slidably connected with the rod holder 225 forms an interlaced state with other tension rods 21 under the action of the spring 220, and the clamping and conveying mechanism 3 drives the cloth to move in the channel between the interlaced tension rods 21;

[0038] The second state is the pre-tightening state: after the cloth clamping and conveying is completed, the pre-tightening mechanism 4 starts to abut against the lower end of the corresponding tension rod 21 which can slide, and presses the tension rod 21 to the column where the other tension rods 21 cannot slide, at this time, the movable tension rod 21 tightly abuts against the cloth, so that the cloth forms a wave-shaped pre-tightening state between the tension rods 21;

[0039] The third state is the tension stretching state: after the cloth is pre-tightened and stretched, the clamping assemblies 1 on the rod holders 225 at both ends and the rod holders 225 are simultaneously moved towards the corresponding direction under the driving of the equidistant transmission rod 222, so as to realize further stretching and tensioning of the cloth, and complete the tension test.

After the transfer seat 31 is transferred to the corresponding position and the cloth is clamped by the clamping assembly 1, the clamping hand 331 releases the cloth, and the cylinder 334 drives the rack to move, thereby driving the gear to rotate, so that the flipping rod 332 rotates 90°, and the vertical clamping rod 337 on the clamping hand 331 is turned to the horizontal, so that the clamping rod 337 falls off the area where the cloth is located, avoiding affecting the tension and movement of the cloth.
