Description

Technical Field

[0001] This invention relates to the field of penetrant testing equipment for rubber products, and particularly to a chemical penetrant testing device for rubber products. Background Technology

[0002] Rubber products are items with various properties and uses, made primarily from natural or synthetic rubber through specific processing techniques. They are widely used in numerous fields, including industry and daily life. For example, in the automotive industry, rubber seals and tires are crucial for vehicle performance and safety; in the medical field, rubber gloves and catheters come into direct contact with the human body. However, during use, rubber products may come into contact with various chemicals, which can penetrate the rubber, affecting its performance, lifespan, and even posing risks to human health and the environment in some cases. Chemical penetration testing devices for rubber products are mainly used to simulate the scenarios of contact between rubber products and various chemicals during actual use. Through specific testing methods and techniques, they accurately measure and analyze parameters such as the penetration rate, penetration depth, and penetration volume of chemicals in rubber, thereby evaluating the barrier properties and anti-penetration capabilities of rubber products. This provides important data for quality control, performance improvement, and safe use of rubber products. Existing chemical penetration testing devices for rubber products are inconvenient to reliably adjust the height of the chemical reagent nozzle during use. This makes it impossible to change the distance between the nozzle and the rubber product surface when dealing with rubber products of varying thicknesses. Even in devices with nozzle height adjustment mechanisms, the adjustment process is often extremely cumbersome and complex. It may require the use of multiple specialized tools to loosen and adjust various nuts and bolts to achieve minute changes in nozzle height. This operation is not only time-consuming and labor-intensive, but also prone to causing nozzle position deviations during adjustment, affecting the accuracy of the test results. Summary of the Invention

[0003] The purpose of this invention is to provide a chemical penetrant testing device for rubber products, which solves the problem that existing chemical penetrant testing devices for rubber products are inconvenient to stably adjust the height of the chemical reagent nozzle.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a chemical substance penetration testing device for rubber products, including a testing platform; The bottom of the test bench is fixedly connected to a support leg, and an adjustment mechanism is installed on the outer wall of the test bench; The adjustment mechanism includes a frame plate fixedly installed on the top of the test bench. A guide plate is fixedly connected to the inner wall of the frame plate. A drive motor is fixedly connected to the top of the frame plate. A threaded rod is fixedly connected to the output shaft of the drive motor through a coupling. A receiving plate is movably connected to the outer wall of the threaded rod. An avoidance groove is provided inside the avoidance groove, and a threaded groove is provided inside the receiving plate.

[0005] Preferably, the threaded rod and the frame plate form a rotating structure, and the threaded rod is threadedly connected to the receiving plate through a threaded groove, so that the threaded rod can rotate to drive the receiving plate to rise and fall.

[0006] Preferably, the guide plate is symmetrically arranged around the central axis of the frame plate, and the receiving plate forms a sliding structure with the guide plate through the clearance groove, which can make the receiving plate move up and down and slide stably.

[0007] Preferably, a chemical reagent cylinder is installed on the top of the receiving plate, a delivery pipe is installed on the outer wall of the chemical reagent cylinder, a micro water pump is installed at one end of the delivery pipe, a reagent nozzle is installed at the output end of the micro water pump, and a monitoring probe is installed on the outer wall of the receiving plate, so that the chemical reagent can be sprayed onto the rubber product through the reagent nozzle.

[0008] Preferably, the miniature water pump is installed at the bottom of the receiving plate, and the monitoring probe is tilted.

[0009] Preferably, a limiting mechanism is installed on the top of the test platform. The limiting mechanism includes a support block fixedly installed on the top of the test platform. A pull rod is movably connected inside the support block. A first limiting plate is fixedly connected to one end of the pull rod. A return spring is installed on one side of the first limiting plate. An anti-slip pad is fixedly connected to the other side of the first limiting plate. A second limiting plate is fixedly connected to the top of the test platform. A storage tray is installed on the top of the test platform.

[0010] Preferably, the pull rod and the support block form a sliding structure, and the pull rod is U-shaped, which allows the pull rod to slide along the support block.

[0011] Preferably, the reset spring is sleeved and installed on the outer wall of the pull rod, and the anti-slip pads are evenly distributed along the inner wall of the first limiting plate, which can improve the stability of the limiting of the storage tray and prevent the storage tray from shifting.

[0012] The present invention provides a chemical penetrant testing device for rubber products, which has the following advantages: With the adjustment mechanism, micro water pump, reagent nozzle and monitoring probe set up, the threaded rod can be rotated by starting the drive motor, so that the receiving plate slides up and down along the frame plate, and drives the reagent nozzle to rise and fall to the required height. This makes it easy to adjust the height of the reagent nozzle according to the actual test requirements, so that the reagent nozzle can be used for penetration testing of rubber products of different thicknesses, thereby improving the applicability of the testing device. Furthermore, with the combined action of the guide plate and the clearance groove, the stability of the sliding and lifting of the receiving plate can be improved, which in turn improves the stability of the reagent nozzle lifting and adjusting, so that the reagent nozzle can stably spray chemical reagents onto the rubber products, thereby improving the accuracy of chemical substance penetration testing of the rubber products. Furthermore, by activating a micro water pump, chemical reagents can be sprayed onto rubber products through a reagent nozzle. The rubber products can be observed through a monitoring probe, thereby enabling real-time monitoring of the chemical penetration of the rubber products. By setting up a test platform, a limiting mechanism, a second limiting plate, and a storage tray, the storage tray for placing rubber products is placed on the test platform so that its outer wall is in contact with the inner wall of the second limiting plate. When the pull rod is released, the first limiting plate can be squeezed by the return spring, which facilitates the limiting of the storage tray. Furthermore, the inner wall of the first limiting plate is fixedly connected with an anti-slip pad, and the inner wall of the second limiting plate is also equipped with an anti-slip pad, which can further improve the stability of the limiting of the storage tray.

[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 1-5 The present invention provides a chemical permeation testing device for rubber products, including a test stand 1.

[0017] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the test bench 1 is fixedly connected to a support leg 2. An adjustment mechanism 3 is installed on the outer wall of the test bench 1. The adjustment mechanism 3 includes a frame plate 31 fixedly installed on the top of the test bench 1. A guide plate 32 is fixedly connected to the inner wall of the frame plate 31. A drive motor 33 is fixedly connected to the top of the frame plate 31. The output shaft of the drive motor 33 is fixedly connected to a threaded rod 34 through a coupling. A receiving plate 35 is movably connected to the outer wall of the threaded rod 34. A clearance groove 36 is provided inside the clearance groove 36. A threaded groove 37 is provided inside the receiving plate 35. The threaded rod 34 and the frame plate 31 form a... The structure is rotating. The threaded rod 34 is threadedly connected to the receiving plate 35 through the threaded groove 37. The guide plate 32 is symmetrically arranged around the central axis of the frame plate 31. The receiving plate 35 and the guide plate 32 form a sliding structure through the clearance groove 36. A chemical reagent cylinder 4 is installed on the top of the receiving plate 35. A delivery pipe 5 is installed on the outer wall of the chemical reagent cylinder 4. A micro water pump 6 is installed at one end of the delivery pipe 5. A reagent nozzle 7 is installed at the output end of the micro water pump 6. A monitoring probe 8 is installed on the outer wall of the receiving plate 35. The micro water pump 6 is installed at the bottom of the receiving plate 35. The monitoring probe 8 is set at an angle.

[0018] By starting the drive motor 33, the threaded rod 34 can be rotated. Since the threaded rod 34 is threadedly connected to the receiving plate 35 through the threaded groove 37, and the receiving plate 35 forms a sliding structure with the guide plate 32 through the clearance groove 36, the receiving plate 35 can slide and rise along the frame plate 31. During this process, the guide plate 32 is always stuck in the clearance groove 36, so that the receiving plate 35 slides and rises stably, thereby driving the reagent nozzle 7 to rise and fall to the required height. When the bottom of the reagent nozzle 7 is close to the rubber product, the micro water pump 6 is started, which can draw out the chemical reagent in the chemical reagent cylinder 4 through the delivery pipe 5 and inject the chemical reagent into the reagent nozzle 7 through the output end of the micro water pump 6, so that the reagent nozzle 7 sprays the chemical reagent onto the rubber product. The chemical penetration of the rubber product can be monitored in real time through the monitoring probe 8, thereby obtaining the resistance data of the tested rubber product to chemical penetration.

[0019] Reference Figure 1 , Figure 3 and Figure 5 As shown, a limiting mechanism 9 is installed on the top of the test bench 1. The limiting mechanism 9 includes a support block 91 fixedly installed on the top of the test bench 1. A pull rod 92 is movably connected inside the support block 91. A first limiting plate 93 is fixedly connected to one end of the pull rod 92. A return spring 94 is installed on one side of the first limiting plate 93. An anti-slip pad 95 is fixedly connected to the other side of the first limiting plate 93. A second limiting plate 10 is fixedly connected to the top of the test bench 1. An anti-slip pad 95 is also provided on the inner wall of the second limiting plate 10. Both the first limiting plate 93 and the second limiting plate 10 are semi-arc-shaped. A tray 11 is installed on the top of the test bench 1. The pull rod 92 and the support block 91 form a sliding structure. The pull rod 92 is U-shaped. The return spring 94 is sleeved and installed on the outer wall of the pull rod 92. The anti-slip pads 95 are evenly distributed along the inner wall of the first limiting plate 93.

[0020] By pulling the lever 92, the lever 92 can slide along the support block 91 and drive the first limiting plate 93 to move. At this time, the return spring 94 is compressed due to the pressure of the first limiting plate 93. The tray 11 for placing rubber products is placed on the test table 1, and the outer wall of the tray 11 is in contact with the inner wall of the second limiting plate 10. The lever 92 is released, and under the action of the return spring 94, the lever 92 can slide back along the support block 91, driving the first limiting plate 93 to press the tray 11. Under the clamping action of the first limiting plate 93 and the second limiting plate 10, the tray 11 can be limited to prevent the tray 11 from shifting during the chemical substance penetration test.
