Description

Technical Field

[0001] This invention relates to the field of tensile strength testing technology, specifically to a device for testing the tensile strength of fiberglass cloth. Background Technology

[0002] Currently, the tensile strength testing of fiberglass cloth needs to follow a standardized process.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-4 The present invention provides a technical solution: a fiberglass cloth tensile strength testing device, including a workbench 1, a work frame 2 installed on the top of the workbench 1, including a testing mechanism 3, a limiting and fixing mechanism 4 and an environmental adjustment mechanism 5; The detection mechanism 3 includes a fixed frame head 302 and a movable mounting block 303. The fixed frame head 302 is provided in the middle of the inner cavity of the working frame 2, and the movable mounting block 303 is movably installed in the inner cavity of the fixed frame head 302. The limiting and fixing mechanism 4 includes a fixed clamping bar 401 and a movable clamping bar 402. The fixed clamping bar 401 is movably installed at the bottom end of the movable mounting block 303 and the top end of the worktable plate 1. The movable clamping bar 402 is provided on the right side of the fixed clamping bar 401.

[0017] The detection mechanism 3 also includes an electric push rod 301, a pressure touch switch 304, and a mounting ring plate 306. The electric push rod 301 is installed at the top of the working frame 2. An installation opening is provided in the middle of the top of the working frame 2. The bottom end of the electric push rod 301 is connected to the top end of the fixed frame head 302. The movable mounting block 303 has an inverted T-shaped cross-section and a rectangular structure when viewed from above. The bottom end of the movable mounting block 303 is connected to the top end of the fixed clamping strip 401 at the top. Several pressure touch switches 304 are equidistantly installed around the bottom of the movable mounting block 303. The mounting ring plate 306 is installed around the bottom of the fixed frame head 302. Observation plates are installed on the front and rear sides of the working frame 2. A control panel is installed on the bottom of the front side of the working frame 2. The electric push rod 301 and the pressure touch switch 304 are electrically connected to the control panel. The detection mechanism 3 also includes silicone top balls 305 and fixing springs 307. The top of the movable mounting block 303 has a round opening. The top of the inner cavity of the fixed frame head 302 is equipped with a fixing spring 307. The bottom end of the fixing spring 307 is connected to the inner cavity of the round opening. Several silicone top balls 305 are installed around the top of the mounting ring plate 306 at the relative position of the pressure touch switch 304. The specific implementation method is as follows: During the testing process, after the fabric is fixed, the electric push rod 301 is activated to retract the telescopic end, and the fixed frame head 302 and the movable mounting block 303 are moved upward, stretching the fixed spring 307. When the fixed frame head 302 moves upward, the silicone top ball 305 contacts and squeezes the pressure touch switch 304, and drives the fixed clamping strip 401 and the movable clamping strip 402 at the top to move upward, thus moving the top of the fabric upward to test the strength of the fabric. The test stops when the pressure value set in advance by the pressure touch switch 304 is reached.

[0018] The upper ends of both sides of the fixed frame head 302 are equipped with stabilizing sliding sleeves 10, and stabilizing sliding rods 9 are slidably installed in the inner cavity of the stabilizing sliding sleeves 10. The top end of the stabilizing sliding rods 9 is connected to the top end of the inner cavity of the working frame 2, and a circular plate is installed at the bottom end of the stabilizing sliding rods 9. A stabilizing base frame is installed at the bottom end of the worktable plate 1. The specific implementation method is as follows: when the fixed frame head 302 moves, it drives the stabilizing sleeve 10 to slide outside the stabilizing slide rod 9, thereby improving the stability and flexibility of the fixed frame head 302 during the movement process.

[0019] The limiting and fixing mechanism 4 further includes a limiting screw 403, a mounting groove 404, an adjusting screw 405, and a mounting slider 406. Each movable clamping bar 402 near the fixed clamping bar 401 is equipped with a limiting screw 403. The left end of the limiting screw 403 is connected to the right side of the fixed clamping bar 401 via a bearing. A threaded sleeve is installed on the movable clamping bar 402 at the position opposite to the limiting screw 403. The top of the worktable 1 has a mounting groove 404. An adjusting screw 405 is mounted inside the mounting groove 404 via a bearing. A mounting slider 406 is movably mounted in the middle of the adjusting screw 405. A mounting screw hole is opened in the middle of the mounting slider 406. A rotating hole is opened on the right side of the mounting groove 404. A rotating plate is installed on the right side of the adjusting screw 405 through the rotating hole. The top of the mounting slider 406 is connected to the bottom end of the fixed clamping bar 401. The limiting and fixing mechanism 4 further includes a detection notch 407, a mounting spring 408, a pressure controller 409, a limiting extrusion block 410, and a protrusion 411. A plurality of detection notches 407 are equidistantly provided on the right side of the fixed clamping bar 401 and the left side of the movable clamping bar 402. A limiting extrusion block 410 is movably mounted within the cavity of each detection notch 407. A plurality of mounting springs 408 are equidistantly mounted on the side of the limiting extrusion block 410 closest to the detection notch 407. One end of each mounting spring 408 away from the limiting extrusion block 410 is connected to one side of the cavity of the detection notch 407. A rubber layer is installed on the side of the limiting extrusion block 410 away from the detection notch 407. A pressure controller 409 is installed on the opposite side of the cavity of the detection notch 407 at both the top and bottom ends. A protrusion 411 is installed on the side of the limiting extrusion block 410 closest to the pressure controller 409. The pressure controller 409 is electrically connected to the control panel. The specific implementation method is as follows: During the testing process, the fabric to be tested is moved into the working frame 2. First, the top of the fabric is fixed, so that the top of the fabric moves between the fixed clamping strip 401 and the movable clamping strip 402. Then, the limiting screw 403 is rotated to drive the movable clamping strip 402 to move towards the fixed clamping strip 401, which in turn drives the limiting squeezing block 410 to move, so that one side of the limiting squeezing block 410 contacts the top of the fabric. As the limiting squeezing block 410 continues to move, it moves towards the inner cavity of the testing recess 407, and squeezes the mounting spring 408. When the fabric is subjected to a strength test, the tensile force generated during the test causes several protrusions 411 to move and contact the pressure controller 409 for compression. The values ​​generated by the pressure controller 409 at each position are fed back to the control panel. When the test is completed and the force borne at different positions during the test needs to be adjusted, the adjusting screw 405 is rotated by rotating the plate. This causes the mounting slider 406 to slide inside the mounting groove 404, which in turn moves the fixed clamping strip 401 and the movable clamping strip 402 at the bottom, thus moving the bottom end of the fixed fabric.

[0020] The environmental adjustment mechanism 5 includes a multi-way solenoid valve 501, a multi-head connecting pipe 502, a mounting plate 503, a heating frame 504, resistance heating tubes 505, a conveying fan 506, and a working humidifier 507. The mounting plate 503 is mounted on the bottom of the workbench 1, and the working humidifier 507 is mounted on the top of the mounting plate 503. The heating frame 504 is mounted on the bottom of the mounting plate 503, and the conveying fan 506 is mounted on the bottom of the heating frame 504. The working humidifier 507 and the heating frame 504 are connected to multi-head connecting pipes 502 via one-way valves on both sides. Several resistance heating tubes 505 are installed inside the heating frame 504. Conveying fans are provided on both sides and at the bottom of the heating frame 504. The workbench 1 has a multi-way solenoid valve 501 installed on both sides of its top. Connection ports are provided on both sides of the workbench 1 at positions opposite to the multi-way solenoid valves 501. The end of the multi-head connecting pipe 502 furthest from the one-way valve passes through the connection port and connects to the bottom of the multi-way solenoid valve 501. A nozzle is installed on the top and one side of the multi-way solenoid valve 501. The multi-way solenoid valve 501, resistance heating tube 505, conveying fan 506, and working humidifier 507 are electrically connected to the control panel. A temperature controller 11 is installed on the left side of the fixed frame head 302, and a humidity controller 12 is installed on the right side of the fixed frame head 302. The temperature controller 11 and humidity controller 12 are electrically connected to the control panel. The specific implementation method is as follows: When simulating the detection environment, first start the nozzle on one side of the multi-way solenoid valve 501, then start the working humidifier 507 to deliver gas into the multi-head connecting pipe 502, and finally spray it into the working frame 2 through the multi-way solenoid valve 501. The humidity inside the working frame 2 is monitored by the temperature controller 11. When the predetermined humidity value is reached, the working humidifier 507 is turned off to stop humidifying the working frame 2, thus realizing detection in a humid environment. When detection is required at high temperature, start the nozzle at the top of the multi-way solenoid valve 501, turn off the working humidifier 507, and start the resistance heating tube 505 and the conveying fan 506. When the airflow is delivered into the heating frame 504 and the resistance heating tube 505, the airflow will form a hot airflow and be delivered into the multi-head connecting pipe 502, and then delivered into the working frame 2 through the multi-way solenoid valve 501 to raise the temperature inside the working frame 2.

[0021] Movable frame plates 6 are installed on both sides of the working frame 2. An operating slot 8 is opened in the middle of each movable frame plate 6. A movable baffle 7 is movably installed on the side of the movable frame plate 6 away from the working frame 2. The top of the movable baffle 7 is connected to the movable frame plate 6 by a hinge. A sealing magnetic ring 13 is installed around the inner cavity of the movable baffle 7 and around the inside of the movable frame plate 6 located in the operating slot 8. The specific implementation method is as follows: when the fabric to be tested is moved into the working frame 2, the bottom end of the movable baffle 7 is moved away from the movable frame plate 6 by the hinge as the axis, so that the operating through slot 8 is directly exposed and the fabric is directly placed into the working frame 2. When the movable baffle 7 is closed, the mutual magnetic attraction between the sealing magnetic rings 13 improves the firmness between the movable baffles 7.
