Description

Technical Field

[0001] This utility model relates to the field of polymer material experimental technology, and in particular to an intelligent temperature-controlled polymer material aging test chamber. Background Technology

[0002] An aging test chamber is a device used to simulate different environmental conditions to accelerate the aging of materials or products. It is widely used in industries such as coatings, plastics, rubber, and textiles. By simulating factors such as light, temperature, and humidity in the natural environment, it assesses the aging conditions that materials may encounter in actual use environments.

[0003] In traditional aging test chambers, ultraviolet lamps are mostly installed at a fixed height. Due to the fixed position of the light source, there may be uneven light distribution inside the chamber. Some areas may be overexposed or underexposed, which affects the accuracy and reliability of the test results. A light source that is in the same position for a long time may produce a local heating effect on the sample, resulting in fluctuations in temperature and humidity, which further affects the stability of the experimental environment and the true reproduction of the material aging process. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent temperature-controlled polymer aging test chamber to solve the above-mentioned problems. This improves upon the fact that most ultraviolet lamps in intelligent temperature-controlled polymer aging test chambers are installed at a fixed height. Due to the fixed position of the light source, uneven light distribution may occur inside the chamber, leading to overexposure or underexposure in certain areas, affecting the accuracy and reliability of the test results. Furthermore, a light source in the same position for an extended period may cause localized heating of the sample, resulting in fluctuations in temperature and humidity, further affecting the stability of the experimental environment and the accurate reproduction of the material aging process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-4 The present invention provides the following technical solution:

[0031] A smart temperature-controlled polymer material aging test chamber includes:

[0032] Experimental chamber 1;

[0033] Mounting plate 2 is fixedly connected to the upper end of experimental chamber 1;

[0034] The first motor 3 is fixedly connected to one side of the mounting plate 2 by bolts;

[0035] Box door 10 is rotatably connected to one side of experimental box 1 via a rotating shaft;

[0036] PLC controller 11 is fixedly connected to one side of the door 10, and the first motor 3 is connected to the PLC controller 11 via signal.

[0037] The mobile irradiation mechanism consists of two sets. Each set includes a threaded rod 4, a limiting rod 5, a pulley 6, a slider 8, and an ultraviolet lamp 9. The threaded rod 4 is rotatably connected inside the experimental chamber 1. The limiting rod 5 is fixedly connected to the upper and lower inner walls of the experimental chamber 1 at their close ends. The pulley 6 is fixedly connected to the circumferential surface of the threaded rod 4. The slider 8 is slidably connected to the circumferential surfaces of the threaded rod 4 and the limiting rod 5. The ultraviolet lamp 9 is fixedly connected to one side of the slider 8.

[0038] Belt 7 is rotatably connected to the circumferential surfaces of two pulleys 6;

[0039] The output shaft of the first motor 3 is fixedly connected to one of the threaded rods 4.

[0040] In a specific embodiment of this utility model, the experimental chamber 1 is the core testing area of ​​the entire equipment. The mounting plate 2 serves as a support platform to support the first motor 3. The first motor 3 drives one of the threaded rods 4 to rotate. The chamber door 10 facilitates sample loading and unloading and provides sealing for the experimental chamber 1. The PLC controller 11 is used to set and control parameters such as temperature, illumination time, and motion frequency. It is connected to the first motor 3, the second motor 13, the condenser 17, and the heater 18 for signal control. The threaded rod 4, the limit rod 5, and the slider 8 are included. The slider 8 has a sliding nut inside. The output shaft of the first motor 3 is fixedly connected to one of the threaded rods 4, and the other threaded rod 4 is linked to it via a belt 7. The threads on the circumferential surfaces of the two threaded rods 4 have opposite directions, i.e., one is a right-hand thread and the other is a left-hand thread, which drives the two sliders 8 to slide in opposite directions. Conversely, the limiting rod 5 is used to prevent the slider 8 from rotating, so that it can only move in a straight line. The pulley 6 and belt 7 are connected by the belt 7, which drives the two sets of moving irradiation mechanisms to move synchronously in opposite directions. The ultraviolet lamp 9 is used to simulate the ultraviolet radiation in sunlight. It should be noted that the installation and use of the ultraviolet lamp 9 and PLC controller 11 are existing technologies and will not be elaborated on in this article. The first motor 3 starts to run and drives the threaded rod 4 connected to it to rotate. Due to the linkage of the belt 7, the two threaded rods 4 rotate synchronously. However, because the threads of the two are opposite, the sliders 8 connected to them will produce reciprocating motions that are relatively close or far apart. This bidirectional moving irradiation method can allow the tested polymer material to receive more diverse and uniformly distributed ultraviolet light during the aging process, avoiding the problem of uneven irradiation caused by traditional fixed light sources or unidirectional movement, and significantly improving the accuracy and repeatability of experimental data.

[0041] Please refer to the details. Figure 1-4 The experimental chamber 1 has a mounting groove 12 on one side. A second motor 13 is fixedly connected to the upper inner wall of the mounting groove 12. A rotating rod 14 is fixedly connected to the output shaft of the second motor 13. The rotating rod 14 is connected to the PLC controller 11 via signal. A placement platform 15 is fixedly connected to the upper end of the rotating rod 14.

[0042] In this embodiment: the mounting slot 12 is used to accommodate the second motor 13, and the inner shell of the mounting slot 12 holds some tools needed for the experiment, making it convenient for personnel to handle. The second motor 13 is used to drive the rotating rod 14 to rotate. The rotating rod 14 is used to drive the placement platform 15 to rotate. The placement platform 15 is used to support the polymer material sample to be tested. When the operator places the polymer material sample to be tested on the placement platform 15 and starts the equipment, the PLC controller 11 sends a control signal to the second motor 13 according to the preset program, so that it drives the rotating rod 14 to rotate. The rotating rod 14 drives the placement platform 15 to rotate periodically, so that the sample continuously changes orientation during the aging process.

[0043] Please refer to the details. Figure 1-4 An anti-slip pad 16 is fixedly connected to the upper end of the placement platform 15. The anti-slip pad 16 is made of rubber.

[0044] In this embodiment: the operator places the polymer material sample to be tested on the placement platform 15 and starts the aging test. The second motor 13 drives the rotating rod 14 to rotate the placement platform 15 periodically. Due to the presence of the anti-slip pad 16, the sample can be firmly attached to the surface of the placement platform 15. Even during long-term operation or frequent start-stop, there will be no abnormalities such as sliding or flipping. The anti-slip pad 16 is made of high-temperature resistant rubber, which enhances the friction between the sample and the placement platform 15 and prevents the sample from shifting or falling due to rotational vibration or airflow disturbance.

[0045] Please refer to the details. Figure 1-4 A condenser 17 is fixedly connected to one inner wall of the experimental chamber 1, and a heater 18 is fixedly connected to one inner wall of the experimental chamber 1. The condenser 17 and the heater 18 are connected to the PLC controller 11 via signal.

[0046] In this embodiment: the condenser 17 is used to reduce the temperature inside the experimental chamber 1 under set conditions to simulate the nighttime cooling or humidity change process in the natural environment; the heater 18 is used to increase the temperature inside the experimental chamber 1 to simulate the daytime high temperature environment or accelerate the aging process; the PLC controller 11 intelligently controls the alternating operation of hot and cold according to the preset aging program to realize temperature cycle aging simulation. It should be noted that how the PLC controller 11, the second motor 13, the condenser 17 and the heater 18 are installed, used and connected by signals are all existing technologies, and will not be described in detail in this article.

[0047] Please refer to the details. Figure 1-4 Two sealing rings 19 are fixedly connected to the circumferential surfaces of the two threaded rods 4 respectively.

[0048] In this embodiment, the sealing ring 19 is made of high-temperature resistant rubber or silicone, which has good elasticity and wear resistance. The installation position is between the side wall of the experimental chamber 1 and the through hole of the threaded rod 4, forming a dynamic sealing structure to prevent heat loss inside the chamber, improve the heat preservation effect, and block external dust or impurities from entering the chamber and affecting the cleanliness of the experimental environment.

[0049] Please refer to the details. Figure 1-4 An observation window 20 is fixedly connected to the surface of the door 10, and a handle 21 is fixedly connected to the surface of the door 10.

[0050] In this embodiment: the observation window 20 allows the operator to observe the aging state of the samples inside the experimental chamber 1 and the operation of the equipment in real time without opening the chamber door 10; the handle 21 allows the operator to easily open or close the chamber door 10, effectively improving the safety and efficiency of equipment use.

[0051] Please refer to the details. Figure 1-4 Multiple gaskets 22 are fixedly connected to the lower end of the experimental chamber 1.

[0052] In this embodiment: the pad 22 is used to improve the stability of the equipment when it is placed, prevent tilting or shaking due to uneven ground, enhance anti-slip performance, and prevent the equipment from shifting during operation.

[0053] Open the chamber door 10 using handle 21, place the polymer sample to be tested on the placement platform 15, and use the anti-slip pad 16 to enhance friction and prevent the sample from slipping during rotation. Close the chamber door 10 to ensure a good seal. Set the temperature cycle program, UV irradiation time and intensity, rotation cycle and speed of the placement platform 15, and reciprocating frequency of the moving irradiation mechanism via PLC controller 11. Start the heater 18 and condenser 17 for constant temperature control. Start the second motor 13, which drives the rotating rod 14 to rotate. The placement platform 15 rotates periodically, allowing the sample to receive UV irradiation from multiple angles. The heater 18 heats up to the target value according to the settings, and the condenser 17... The system automatically starts during the cooling phase to simulate day and night cycles. The PLC controller 11 monitors and adjusts the temperature and humidity environment throughout the process. Then, the first motor 3 is started, which drives one of the threaded rods 4 to rotate. The other threaded rod 4 rotates in the opposite direction via the belt 7. Since the threads of the two threaded rods 4 are opposite, the slider 8 drives the ultraviolet lamp 9 to reciprocate by moving relatively closer or further away, realizing dynamic illumination simulation and improving the uniformity of illumination. This bidirectional moving irradiation method allows the tested polymer material to receive more diverse and uniformly distributed ultraviolet light during the aging process, avoiding the uneven irradiation problem caused by traditional fixed light sources or unidirectional movement, and significantly improving the accuracy and repeatability of experimental data.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art. 。
