[0015] The technical scheme of the utility model will be further described below by examples and in conjunction with the drawings.
[0016] Example:
[0017] The utility model discloses a kind of zipper durable performance detection devices, as shown in Figure 1 known Figure 3 It includes bottom plate 1, zipper fixing mechanism 2, pull tab clamping plate 3 and driving mechanism.
[0018] Zipper fixing mechanism 2 is arranged at the both ends of bottom plate 1, and the zipper fixing mechanism includes frame body 21, screw rod 24, knob 23 and pressing plate 22. The frame body 21 is composed of a top plate and two vertical plates arranged oppositely below the top plate. The top plate is provided with a first screw hole. The pressing plate 22 is slidingly arranged between the two vertical plates. The screw rod 24 is arranged in the first screw hole. The lower end of the screw rod 24 is rotatably connected with the pressing plate 22. The upper end of the screw rod 24 is fixedly connected with the knob 23. By rotating the knob, the screw rod can be moved up and down to drive the pressing plate to translate vertically, thereby clamping and fixing the end of the zipper.
[0019] The driving mechanism is arranged on the upper end of the two zipper fixing mechanisms 2, and is provided with two groups of driving mechanisms arranged at the two ends of the top plate respectively. The driving mechanism comprises a driving motor 41, a lead screw 42 and a seat body 43. The driving motor 41 and the seat body 43 are oppositely arranged on the same side of the two top plates. One end of the lead screw 42 is connected with the driving motor 41, and the other end of the lead screw 42 is rotatably connected with the seat body 43. The pull tab clamping plate 3 is arranged on the lead screw through threads. When the driving motor 41 operates, the pull tab clamping plate 3 can reciprocate along the lead screw.
[0020] The pull tab clamping plate 3 comprises a movable plate 31 and a clamping plate 32. The upper end of the movable plate 31 is connected with the driving mechanism and is driven by the driving mechanism to reciprocate. The clamping plate 32 is detachably connected with the movable plate 31. In this embodiment, the upper end of the movable plate 31 is provided with a second screw hole 33 on each side. The movable plate 31 is arranged on the lead screw of the driving mechanism through the second screw hole 33. The lower end of the movable plate 31 is provided with a threaded column 34 on each side. The clamping plate 32 is provided with a through hole matched with the threaded column 34. The clamping plate is arranged on the movable plate 31 through the through hole and the threaded column and is fixed through a nut 34. The side of the movable plate 31 facing the clamping plate is provided with a pressure sensor. The side of the clamping plate 32 facing the movable plate is provided with a rubber layer. The pull tab clamping plate 3 is used for clamping and fixing the pull tab of the zipper and roughly detecting the resistance received by the puller during the opening of the zipper through the pressure sensor.
[0021] When the zipper durability detection device in this embodiment is used, first, the two knobs are rotated to lift the pressing plate. Then, the first end of the zipper to be tested is placed in the gap between the first end of the bottom plate and the pressing plate and the corresponding knob is rotated to clamp and fix the first end of the zipper to be tested. Then, the second end of the zipper to be tested is passed through the gap between the second end of the bottom plate and the pressing plate. In the case that the zipper is kept taut, the corresponding knob is rotated to clamp and fix the second end of the zipper to be tested. Then, the pull tab clamping plate clamps the pull tab of the zipper to be tested. After ensuring that the pull tab is clamped firmly, the driving mechanism is started to drive the pull tab clamping plate to reciprocate and realize the opening and closing of the zipper multiple times. During the reciprocation of the pull tab clamping plate, the pressure value detected by the pressure sensor on the movable plate changes according to the moving direction. In the case that the rotating speed of the motor in the driving mechanism is unchanged, the main factor affecting the change of the pressure value is the smoothness of the opening and closing of the zipper, which is related to the wear of the zipper teeth. The more serious the wear of the zipper teeth is, the lower the smoothness of the opening and closing of the zipper is, and the greater the pressure detected by the pressure sensor is. Therefore, when the real-time pressure detection reaches a difference greater than a set value from the pressure value detected by the pressure sensor at the initial time, it can be determined that the zipper has mild wear, moderate wear or severe wear. At this time, the reciprocation times of the pull tab clamping plate can be used to roughly determine the opening and closing times corresponding to the mild wear, moderate wear and severe wear of the zipper to be tested, and more accurate durability data can be obtained for subsequent improvement.

Various modifications or changes in the specific embodiments described herein can occur to those skilled in the art to which the application pertains without departing from the spirit of the application, and it is understood that such modifications or changes are to be considered as within the scope of the application as defined by the appended claims.
