Technical Field

[0001] This utility model relates to the technical field of nitrile latex glove production, and in particular to a strength testing device for nitrile latex gloves. Background Technology

[0002] Nitrile latex gloves, commonly known as NBR gloves, are a widely used type of personal protective equipment (PPE), especially favored in industries such as medical, laboratory, food processing, and cleaning services due to their excellent physical properties and chemical stability.

[0003] However, the current testing process for nitrile latex gloves only involves simple stretching and rough calculations without accurate readings, resulting in inaccurate test results and making it easy for substandard nitrile latex gloves to enter the market. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a strength testing device for nitrile latex gloves, which can accurately test the tensile strength of nitrile gloves by setting this device, thereby ensuring the production quality of nitrile gloves.

[0005] This utility model discloses a strength testing device for nitrile latex gloves, comprising a workbench, a protective cover, a feed gate, a first handle, two sets of clamping frames, two sets of bidirectional screws, four sets of moving blocks, four sets of clamping plates, two sets of second handles, a tensile tester, screws, a vertical plate, a motor, a threaded pipe, two sets of bevel gears, and a controller. The protective cover is installed on the top of the workbench, and a feed inlet is provided at the left front end of the protective cover. The feed gate is rotatably installed at the feed inlet of the protective cover. The first handle is installed on the right front end of the feed gate. The left clamping frame of the two sets of clamping frames is fixedly installed on the left side of the top of the workbench, and the bottom end of the right clamping frame is slidably connected to the top of the workbench. Each set of clamping frames has an installation groove at its inner end. The two sets of bidirectional screws are rotatably installed in the installation grooves of the two sets of clamping frames, and the top ends of the two sets of bidirectional screws are located at the two sets of clamping frames. Outside the clamping frame, four sets of moving blocks slide within the mounting slots of two sets of clamping frames. Each of the four sets of moving blocks has a threaded hole in its center. The four sets of moving blocks are threadedly connected to two sets of bidirectional screws. Four clamping plates are installed on the outer ends of the four sets of moving blocks. Two sets of second handles are installed on the top ends of the two sets of bidirectional screws. A tension detector is installed on the right end of the right clamping frame. The left end of the screw is connected to the right end of the tension detector. A vertical plate is installed on the right side of the top of the workbench. A motor is installed on the upper right side of the vertical plate. A threaded tube is rotatably installed in the middle of the vertical plate. The threaded tube meshes with the screw. Two sets of bevel gears are installed on the threaded tube and the motor output end, respectively. The two sets of bevel gears mesh. A through hole is provided on the right end of the protective cover. The position of the through hole corresponds to that of the screw and the protective cover. A controller is installed at the front end of the workbench. The controller is electrically connected to the tension detector.

[0006] Preferably, four sets of rollers are provided at the four corners of the bottom of the workbench.

[0007] Preferably, it also includes four sets of electric actuators. The left front, left rear, right front and right rear sides of the bottom of the worktable are provided with mounting slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The feed door is opened by the first handle, and the fabric cut from the nitrile gloves is placed between four sets of clamping plates. Then, two sets of second handles are used to rotate two sets of bidirectional screws, which are threadedly connected to four sets of moving blocks. The four sets of moving blocks drive the four sets of clamping plates to move inward, clamping the fabric. The motor is then turned on, and the motor drives the threaded tube to rotate via two sets of bevel gears. The threaded tube is threadedly connected to the screw, which drives the right-side clamping frame to move to the right via a tension detector. The tension detector detects the tension, and the fabric is stretched. When the fabric breaks, the maximum tension value of the tension detector is transmitted to the controller, thus determining the precise tensile strength of the nitrile gloves. By setting up this device, the tensile strength of the nitrile gloves can be accurately detected, thereby ensuring the production quality of the nitrile gloves. Attached Figure Description
