Description

Technical Field

[0001] The utility model relates to the technical field of rubber product experiments, in particular to an ozone resistance experiment device for rubber products. Background Art

[0002] The structure of the rubber ring is annular and is made of soft, elastic rubber material. It is used to provide a sealing effect to prevent the leakage of liquid or gas. The purpose of the ozone resistance test of the rubber ring is to evaluate the durability and reliability of the rubber material in an ozone environment in order to select suitable materials for specific applications. By simulating the ozone environment, the experiment accelerates the aging process of the rubber material and observes its performance changes, such as hardening, cracking, discoloration, etc. This helps to determine the life and performance of the rubber material, and is used to improve the material formula and manufacturing process, and improve the ozone resistance. For example, a rubber product ozone resistance tensile test device disclosed in the authorization announcement number CN211122299U includes a base, a motor is provided on the top of the base, a first threaded rod is provided at the end of the output shaft of the motor, a moving block is provided on the outside of the first threaded rod, the first threaded rod is connected to the output shaft end of the motor in a transmission manner, the first threaded rod is threadedly connected to the moving block, and cross bars are provided on both sides of the moving block. By providing a transparent plate and a limiting plate, it is different from the prior art. For example, the transparent plate is changed from a horizontal state to a vertical state so that the transparent plate contacts the rubber pad, which can protect the transparent plate. The transparent plate is then placed between the limiting plate and the outer frame, which can allow the transparent plate to be in close contact with the rubber pad to prevent shaking. However, this technical solution does not actively supply ozone to the rubber product (rubber ring) when conducting an ozone resistance test on the rubber product. Ozone is a gas existing in the atmosphere and has a significant impact on the aging and deterioration of rubber materials. Without active ozone supply, it is difficult to truly simulate the exposure of the rubber product in the actual use environment, and it is impossible to evaluate the true durability of the rubber product in the ozone environment.

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-5 The present invention provides an embodiment of an ozone resistance test device for rubber products, comprising a chassis 1 and a sliding cover 3 slidably mounted on the outer walls of both sides of the chassis 1. A PLC control panel 5 is mounted on the outer wall of one side of the chassis 1. Guide rails 101 are fixed to the outer walls of both sides of the chassis 1. The sliding cover 3 is slidably mounted on the two guide rails 101. The inner wall of the sliding cover 3 contacts the outer wall of the chassis 1.

[0021] A side guard 2 is fixed to the outer wall of the chassis 1 away from the sliding cover 3. A sliding telescopic member is installed on the top of the chassis 1. A main tensioning member 9 is installed on the movable end of the sliding telescopic member. A secondary tensioning member 10 is installed on the top of the side guard 2 on the same horizontal reference plane as the main tensioning member 9. The rubber ring product to be treated with ozone resistance test is set between the main tensioning member 9 and the secondary tensioning member 10.

[0022] The sliding telescopic member includes a support 6 fixed to one side of the top of the chassis 1, and a cylinder 7 installed on the outer wall of one side of the support 6. A T-arm 8 is fixed to the top of the piston rod of the cylinder 7, and a main tightening member 9 is installed at the bottom end of the T-arm 8. The input end of the cylinder 7 is electrically connected to the output end of the PLC control panel 5. When the rubber ring is installed, the staff starts the cylinder 7 through the PLC control panel 5, and the cylinder 7 pulls the T-arm 8 and the main tightening member 9 toward the direction of the air injection pipe 13 until the rubber ring is in a tensioned state. Then the staff pushes the sliding cover 3 so that the area where the rubber ring is located is covered, forming a relatively sealed environment.

[0023] A hydraulic cylinder 14 is mounted on the inner wall of one side of the chassis 1. An air jet 13 is mounted on the top of the piston rod of the hydraulic cylinder 14. Guide posts are slidably mounted on both sides of the interior of the chassis 1. A flat plate is fixed to the top of the guide posts. One end of the flat plate is fixedly connected to the outer wall of one side of the air jet 13. The hydraulic cylinder 14 pushes the air jet 13 in the X-axis direction, thereby changing the gas injection point of the air outlet 1301.

[0024] An air outlet 1301 is provided on one side of the top of the air jet pipe 13 and at the opening away from the hydraulic cylinder 14. An ozone pumping unit 4, which is interconnected with the air inlet end of the air jet pipe 13, is mounted on the outer wall of one side of the chassis 1. The output end of the PLC control panel 5 is electrically connected to the sliding telescopic member, the hydraulic cylinder 14, and the input end of the ozone pumping unit 4. The hydraulic cylinder 14 is activated through the PLC control panel 5, and the hydraulic cylinder 14 pushes the air jet pipe 13 to move horizontally, thereby adjusting the relative position between the air jet pipe 13 and the rubber ring until the air outlet 1301 of the air jet pipe 13 is located below the rubber ring.

[0025] The ozone pumping unit 4 works and feeds ozone gas into the injection pipe 13. At this time, the ozone gas is ejected from the two gas outlets 1301, that is, there are injection points of ozone gas in both the horizontal and vertical directions.

[0026] The main tensioning member 9 and the auxiliary tensioning member 10 have the same structural composition. The main tensioning member 9 includes a support 901 fixed to the bottom end of the T-arm 8, and a baffle 902 fixed to the bottom end of the support 901. The support 901 and the baffle 902 support the rubber ring, and the baffle 902 prevents the rubber ring from falling off the support 901, thereby ensuring the tension stability of the rubber ring.

[0027] A sliding guide structure 11 is provided at the top of the chassis 1 for assisting the sliding of the T-arm 8. The sliding guide structure 11 includes guide sleeves fixed on both sides of the top of the chassis 1 and a straight rod slidably installed inside the guide sleeve. One end of the straight rod is fixedly connected to the outer wall of one side of the T-arm 8. When the cylinder 7 pushes the T-arm 8 to move, the sliding guide structure 11 improves the sliding stability of the T-arm 8, the main tightening member 9 and other components.

[0028] The ozone pumping unit 4 includes an ozone generator 401 installed on the outer wall of one side of the chassis 1, and an electric switch valve 402 installed at the air outlet of the top of the ozone generator 401, an air pump 403 is installed on the top of the ozone generator 401 on one side of the electric switch valve 402, the air inlet end of the air pump 403 and the air outlet end of the electric switch valve 402 are connected to each other, the air outlet end of the air pump 403 and the air inlet end of the injection pipe 13 are connected to each other, the air inlet end of the air pump 403 is installed with an air supply pipe 405 for connecting to the air outlet end of the electric switch valve 402, the air outlet end of the air pump 403 is installed with an air guide hose 404, one end of the air guide hose 404 extends to the interior of the chassis 1 and is installed with a corrugated hose 12, the top of the corrugated hose 12 is connected to the air inlet end of the injection pipe 13;

[0029] Ozone generator 401 generates a sample, and electric switch valve 402 is in a normally open state under the control of PLC control panel 5. Then, air pump 403 can deliver ozone gas into corrugated hose 12 through electric switch valve 402, air supply pipe 405, and air guide hose 404, and finally into air injection pipe 13 and ejected through air outlet 1301. In this process, ozone pumping unit 4 simulates different ozone exposure conditions according to different application requirements and environmental conditions. By adjusting the ozone supply time and concentration, the ozone resistance and aging rate of the rubber ring can be better evaluated.

[0030] By actively supplying ozone, the aging process of the rubber ring can be accelerated, thereby shortening the experimental time. By setting the ozone injection point, the ozone concentration and the contact time between the rubber ring and ozone can be precisely controlled.

[0031] When the embodiment of the present application is in use, the staff first sets the rubber ring product to be subjected to the ozone resistance test between the main tensioning piece 9 and the auxiliary tensioning piece 10. When the rubber ring is set, the staff turns on the cylinder 7 through the PLC control panel 5, and the cylinder 7 pulls the T-arm 8 and the main tensioning piece 9 to move toward the direction of the jet pipe 13 until the rubber ring is in a tensioned state. At this time, the staff pushes the sliding cover 3 so that the area where the rubber ring is located is covered to form a relatively sealed environment. Then the staff turns on the hydraulic cylinder 14 through the PLC control panel 5 again, and the hydraulic cylinder 14 pushes the jet pipe 13 to move horizontally, thereby adjusting the relative position relationship between the jet pipe 13 and the rubber ring until the air outlet 1301 of the jet pipe 13 is located below the rubber ring. Then the ozone pumping unit 4 works, and the ozone pumping unit 4 feeds ozone gas into the injection pipe 13. At this time, ozone gas is ejected from two outlet holes 1301, that is, there are ozone gas injection points in both the horizontal and vertical directions. The ozone gas injection points in the vertical direction quickly break the rubber molecular chains in the rubber ring and destroy the cross-linking structure, causing the rubber material to age and deteriorate, and then lose its original elasticity and durability. By actively supplying ozone, this device can more realistically simulate the ozone exposure conditions of the rubber ring in the actual use environment. Actively supplying ozone and setting injection points can more comprehensively evaluate the performance changes of the rubber ring. Setting injection points can concentrate ozone in specific areas, allowing more accurate observation and evaluation of these performance changes, which helps provide a more detailed rubber ring performance evaluation and facilitate the selection of appropriate materials and designs.
