The structure of the entire testing device is simplified, thus reducing its production cost and making it more suitable for widespread use. Moreover, the device is simpler to use and more convenient to conduct tests.

[0004] However, the existing technology described above cannot simulate the damage caused by finger pulling during daily use of PVC gloves in tensile testing. Utility Model Content

[0005] The technical problem to be solved by this utility model is:

[0006] Existing technology cannot simulate the tensile testing of PVC gloves during daily use.

[0007] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a tensile testing device for PVC glove production, including a base plate, a testing traction device and a position adjustment component. The testing traction device and the position adjustment component are both fixedly erected on the base plate. The testing traction device includes a transmission structure, a simulated palm structure and a simulated finger limiting structure. The transmission structure is erected on the base plate, the simulated palm structure is fixedly mounted on the transmission structure, and the simulated finger limiting structure is detachably mounted on the simulated palm structure.

[0008] Furthermore, the transmission structure includes a lead screw rotating frame, a transmission motor, a screw, and a slider with a nut. The lead screw rotating frame is fixedly erected on the base plate. The simulated finger limiting structure is located at one end of the lead screw rotating frame. One end of the transmission motor is rotatably mounted on the lead screw rotating frame, and the other end is fixedly connected to the output shaft of the simulated finger limiting structure. The screw and the transmission motor are threadedly connected and slide relative to each other with the simulated finger limiting structure.

[0009] Furthermore, the simulated hand structure includes a support frame, a servo motor, a transmission shaft, and a mounting bracket. The support frame is fixedly mounted on a slider with a nut.

The extension frame is arranged in a cross shape and matches the shape of the limiting groove. The extension frame is bolted into the limiting groove.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, the present invention proposes a tensile testing device for PVC glove production, comprising a base plate 1, a testing traction device 2, and a position adjustment component 3. Both the testing traction device 2 and the position adjustment component 3 are fixedly erected on the base plate 1. The testing traction device 2 includes a transmission structure 4, a simulated palm structure 5, and a simulated finger limiting structure 6. The transmission structure 4 is erected on the base plate 1, the simulated palm structure 5 is fixedly mounted on the transmission structure 4, and the simulated finger limiting structure 6 is detachably mounted on the simulated palm structure 5.

[0024] like Figure 1-3 As shown, for traction, the transmission structure 4 includes a lead screw rotating frame 7, a transmission motor 8, a screw 9, and a slider 10 with a nut. The lead screw rotating frame 7 is fixedly erected on the base plate 1. The simulated finger limiting structure 6 is located at one end of the lead screw rotating frame 7. One end of the transmission motor 8 is rotatably mounted on the lead screw rotating frame 7, and the other end is fixedly connected to the output shaft of the simulated finger limiting structure 6. The screw 9 is threadedly connected to the transmission motor 8 and slides relative to the simulated finger limiting structure 6.

[0025] like Figure 1-3 As shown, in order to adjust the stability between the simulated finger and the glove and facilitate hooking the glove, the simulated hand structure 5 includes a support frame 11, a servo motor 12, a transmission shaft 13 and a mounting frame 14. The support frame 11 is fixedly mounted on the slider 10 with a nut. The servo motor 12 is located on one side of the support frame 11 and its output shaft passes through the support frame 11. The transmission shaft 13 rotates relative to the support frame 11 and is fixedly connected to the output shaft of the servo motor 12. The mounting frame 14 is fixedly mounted on the transmission shaft 13.

[0026] To facilitate the installation of the simulated finger limiting structure 6 and to test different pressures on the glove with different numbers of fingers, the mounting frame 14 is provided with three sets of cross-shaped limiting grooves 15.

[0027] To simulate the pulling of the glove by the fingers, the simulated finger limiting structure 6 includes an extension frame 16, a small motor 17, and simulated fingers 18. The extension frame 16 is arranged in a cross shape and matches the shape of the limiting groove 15. The extension frame 16 is bolted to the limiting groove 15. The small motor 17 is provided at the end of the extension frame 16 away from the limiting groove 15. The output shaft of the small motor 17 passes through the extension frame 16. The servo motor 12 is fixed on the small motor 17.

[0028] To facilitate testing at different positions, the position adjustment assembly 3 includes a rotating motor 19 and a platform 20. The rotating motor 19 is fixed on the base plate 1, and the platform 20 is fixed on the rotating motor 19 by a connecting bracket.

[0029] To increase friction while protecting the glove, the simulated finger 18 is covered with silicone.

[0030] To simulate a glove being worn on the palm, the platform 20 is shaped like a hand.

[0031] In practical use, the user places the device at the location where the PVC glove test is to be conducted, puts the PVC glove on the glove stand 20, and installs the corresponding number of simulated finger limiting structures 6 into the limiting grooves 15 according to the number of fingers to be tested. The simulated fingers 18 fasten the edge of the glove. If necessary, they can be put on manually. The small motor 17 drives the simulated fingers 18 to rotate downwards to curl the edge. The servo motor 12 drives the simulated palm and wrist to curl the edge inwards again. Since the simulated fingers 18 are covered with silicone, the friction can be increased. During traction, the transmission motor 8 drives the slider 10 with the nut to move downwards to complete the tensile test. The condition of the glove can be observed as needed. Rotating the motor 19 can change the direction of the glove stand 20, thus facilitating the testing of different positions. The above is the entire usage process of the PVC glove production tensile testing device.
