[0031] The following is only a preferred embodiment of the present application, and does not limit the protection scope of the present application.

[0033] The conventional zipper reciprocating pulling test machine only adjusts the pulling force by the scales on the longitudinal spring scale 92 and the lateral spring scale 91, however, due to metal fatigue, the longitudinal spring scale 92 and the lateral spring scale 91 will have errors after long time use, and need to be calibrated regularly, when errors are found during calibration, the previously tested data will be invalid, while the utility model can monitor the change of pulling force in real time during testing through the lateral tension sensor 96 and the longitudinal tension sensor 97, ensure that the pulling force remains in a constant range during testing, and can read the pulling force value before testing to facilitate accurate adjustment of the pulling force of the lateral spring scale 91 and the longitudinal spring scale 92, without the need to adjust according to the scales on the lateral spring scale 91 and the longitudinal spring scale 92, improve the adjustment accuracy, without the need to regularly calibrate the lateral spring scale 91 and the longitudinal spring scale 92, improve the effectiveness of the test data, and avoid invalid test data caused by errors of the lateral spring scale 91 and the longitudinal spring scale 92. Of course, the lateral spring scale 91 and the longitudinal spring scale 92 can be directly replaced by springs without the need to use spring scales.

[0034] Specifically, each transverse clamping mechanism 8 comprises a limiting assembly 81, a transverse clamp 82, a guide pulley 83 and a connecting rope 84. The transverse clamp 82 is slidingly installed on the mounting plate 2. The guide pulley 83 is rotatably installed on the mounting plate 2 and located outside the transverse clamp 82.

The limiting assembly 81 is in limiting cooperation with the transverse clamp 82. The first end of the connecting rope 84 is fixedly connected with the transverse clamp 82. The second end of the connecting rope 84 is fixedly connected with the upper part of the transverse tension sensor 96 after passing through the guide pulley 83. The movement stroke of the transverse clamp 82 is limited by the limiting assembly 81. When the transverse clamping mechanism 8 is clamped, the side of the zipper is first fixed on the transverse clamp 82, so that the distance between the chain of the zipper and the transverse clamp 82 is 5 mm. When the zipper is in the closed state, the distance between the limiting assembly 81 and the transverse clamp 82 is kept at 5 mm, so as to prevent the opening angle of the zipper from being too large and causing damage to the zipper.

[0035] Specifically, the transverse clamping mechanism 8 and the mounting plate 2 are provided with a transverse clamping sliding rail 85 and a transverse clamping sliding block. The transverse clamping sliding rail 85 is obliquely arranged on the mounting plate 2, and the transverse clamping sliding rail 85 is 10° with the horizontal direction. The transverse clamping sliding block is slidingly installed on the transverse clamping sliding rail 85, and the transverse clamp 82 is fixedly installed on the transverse clamping sliding block. The limiting assembly 81 comprises a limiting screw 811, a limiting adjusting nut 812 and a fixed column 813. The fixed column 813 is fixedly installed on the mounting plate 2. The fixed column 813 is provided with a threaded hole penetrating through the fixed column 813. The limiting screw 811 is threadedly connected to the threaded hole. The adjusting nut is threadedly connected to the limiting screw 811 and is in limiting cooperation with the fixed column 813. The inner end of the limiting screw 811 is in limiting cooperation with the transverse clamp 82. The mounting plate 2 and the transverse clamp 82 are connected by the transverse clamping sliding rail 85 and the transverse clamping sliding block, so as to improve the smoothness of the movement of the transverse clamp 82, reduce the friction force, avoid the increase of the tension force caused by the friction force, keep the tension force in a constant range during testing, rotate the limiting screw 811 to adjust the distance between the limiting screw 811 and the transverse clamp 82, first tighten the limiting screw 811 when the zipper is in the closed state, so that the limiting screw 811 abuts against the transverse clamp 82, then loosen the limiting screw 811 by 5 turns. The distance between the limiting screw 811 and the transverse clamp 82 is increased by 1 mm for each turn, so as to adjust the distance between the limiting screw 811 and the transverse clamp 82 to 5 mm, and then tighten the limiting adjusting nut 812 to adjust the limiting screw 811, so as to complete the clamping of the transverse clamping mechanism 8. The structure is simple and convenient to adjust.

[0036] Specifically, the zip reciprocating pulling testing machine is further provided with a damage sensing device 86, which comprises a damage adjusting screw 861, a damage sensing nut 862, a damage locking nut 863 and a proximity sensor 864. The damage adjusting screw 861 is fixedly installed on the connecting rope body 84 of any one of the transverse clamping mechanisms 8. The damage sensing nut 862 and the damage locking nut 863 are both threadedly connected to the damage adjusting screw 861 and abut against each other. The proximity sensor 864 is fixedly installed on the mounting plate 2 and located beside the damage adjusting screw 861. The proximity sensor 864 is electrically connected to the control device 3, and the damage sensing nut 862 is in sensing cooperation with the proximity sensor 864. After the zip is fixed, the damage sensing nut 862 is adjusted to be beside the proximity sensor 864, so that the damage sensing nut 862 triggers the proximity sensor 864. Then, the damage sensing nut 862 is rotated for 1-3 turns, so that the damage sensing nut 862 is located above the proximity sensor 864. During the test, the damage sensing nut 862 does not trigger the proximity sensor 864 in normal state. When the zip is damaged, the damage sensing nut 862 moves downward to trigger the proximity sensor 864, so as to determine that the zip is damaged. At this time, the reciprocating driving mechanism 4 automatically stops, the damage sensing device 86 automatically determines whether the zip is damaged, so as to automatically stop and complete the test, thereby avoiding continuous test after the zip is damaged, and invalid data is generated. When the small zip is tested, the damage sensing nut 862 may accidentally trigger the proximity sensor 864 due to small transverse pulling force. At this time, the damage sensing device 86 is switched to a counting mode, and the number of times that the damage sensing nut 862 triggers the proximity sensor 864 is counted to calculate the test times.

[0037] Specifically, the longitudinal clamping mechanism 7 comprises a longitudinal connecting plate 71, a horizontal detection sheet 72, a longitudinal fixed rod 73 and two longitudinal clamps 74, the longitudinal fixed rod 73 is fixedly installed on the mounting plate 2, the middle part of the longitudinal connecting plate 71 is provided with a vertical longitudinal sliding groove 712, the longitudinal fixed rod 73 is in sliding fit with the longitudinal sliding groove 712, the horizontal detection sheet 72 is fixedly installed on the outer end of the longitudinal fixed rod 73 and located on the front side of the longitudinal connecting plate 71, the two longitudinal clamps 74 are respectively rotatably installed on the left and right sides of the upper part of the longitudinal connecting plate 71, the upper parts of the two longitudinal tension sensors 97 are rotatably installed on the left and right sides of the lower part of the longitudinal connecting plate 71, and the front side of the longitudinal connecting plate 71 is provided with a horizontal scale line 711.

The upper adjusting nut 94 is in abutting fit with the upper part of the tension adjusting plate 22, and the lower adjusting nut 95 is in abutting fit with the lower part of the tension adjusting plate 22. After the longitudinal clamping mechanism 7 and the transverse clamping mechanism 8 are clamped, the distance between the transverse spring scale 91 and the longitudinal spring scale 92 and the tension adjusting plate 22 is adjusted by adjusting the lower adjusting nut 95, so that the tension is adjusted, when the tension is adjusted, the transverse tension sensor 96 and the longitudinal tension sensor 97 transmit the tension value to the control device 3, the tension value is read by the control device 3, so that the tension is accurately adjusted, and when the adjustment is completed, the upper adjusting nut 94 is locked to ensure that the tension is constant during testing.

[0039] Specifically, the reciprocating driving mechanism 4 comprises a servo driving motor 41, a first transmission rod 42 and a second transmission rod 43, the servo driving motor 41 is electrically connected with the control device 3, the control device 3 is provided with a torque adjusting knob 31 and a rotating speed adjusting knob 32, a first end of the first transmission rod 42 is fixedly connected with an output shaft of the servo driving motor 41, a second end of the first transmission rod 42 is rotatably connected with a first end of the second transmission rod 43, and a second end of the second transmission rod 43 is rotatably connected with the reciprocating clamping mechanism 5. The reciprocating driving mechanism 4 of the conventional zipper reciprocating pulling test machine cannot adjust the rotating speed and the torque, the test parameter adjustability is poor, and the zipper is prone to be damaged when the chain of the zipper is stuck. The utility model can test different types of zippers by adjusting the torque and the rotating speed of the servo driving motor 41 through the torque adjusting knob 31 and the rotating speed adjusting knob 32, and can prevent the fabric from being damaged when the zipper is stuck.
