Description

Technical Field

[0001] This utility model relates to the field of plastic aging testing technology, and in particular to a plastic rattan aging test device. Background Technology

[0002] With the diversification of people's demands for outdoor leisure, decoration, and construction, plastic rattan is increasingly widely used in the market due to its advantages such as lightweight, weather resistance, and ease of processing. However, in actual use, plastic rattan is exposed to the outdoor environment for a long time and is affected by a combination of environmental factors such as ultraviolet radiation, temperature changes, humidity fluctuations, and oxygen, leading to irreversible changes in its physical properties (such as strength and toughness) and chemical structure (such as molecular chain breakage and cross-linking), resulting in aging phenomena such as fading, brittleness, and decreased strength, which seriously affects its service life and aesthetics. In order to accurately evaluate the aging resistance of plastic rattan and predict its service life under different environmental conditions, it is necessary to establish a scientific and reasonable aging test device and method to simulate the actual use environment and conduct accelerated aging tests on plastic rattan, so as to provide a strong basis for product development and quality control. Traditional aging test methods often have problems such as inaccurate simulation of the test environment, difficulty in precise control of test parameters, and cumbersome sampling and testing processes, which cannot comprehensively and realistically reflect the aging of plastic rattan in actual use. Therefore, it is necessary to design a more complete and efficient plastic rattan aging test device.

[0003] Chinese patent discloses an aging test device for plastic rattan used in outdoor leisure products (publication number: CN215414941 U), which includes an ultraviolet aging machine and a test plate. The test plate is placed on the body of the ultraviolet aging machine. The front of the test plate is provided with a test piece slot, and a test piece is fixed in the test piece slot. The back of the test plate is provided with a label slot, which corresponds to the position of the test piece slot on the front of the test plate. However, this aging test device has problems such as inaccurate simulation of the test environment, difficulty in accurately controlling the test parameters, and cumbersome sampling and testing processes. It cannot comprehensively and realistically reflect the aging of plastic rattan in actual use. Therefore, there is a need for an aging test device for plastic rattan. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing aging test devices, such as inaccurate simulation of the test environment, difficulty in precisely controlling test parameters, and cumbersome sampling and testing processes, which prevent them from comprehensively and accurately reflecting the aging of plastic rattan in actual use. Therefore, this invention proposes an aging test device for plastic rattan.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The plastic rattan aging test device of this utility model includes a test chamber and an electrical cabinet, characterized in that: the test chamber includes a base, a box body is provided on the base, a light-emitting component is provided on the top of the box body, a sample rack is provided inside the box body, a sampling component is provided on one side of the box body, a lifting component is provided on one side of the light-emitting component, an upper door is provided on one side of the box body, an observation window is provided on one side of the upper door surface, a display screen is provided above the observation window, a pull rod is provided on one side of the upper door, a lower door is provided on one side of the base, and a plug is provided on one side of the box body. Improving test accuracy: Through reasonable structural design, such as top lighting components, internal sample racks, and good sealing (hole plug effect), a relatively stable, uniform, and precisely controllable aging test environment can be created for plastic rattan. This allows the test results to more accurately reflect the aging status of plastic rattan in actual use, which helps researchers to conduct in-depth research on the aging characteristics of plastic rattan and provides a reliable basis for improving the formulation and production process of plastic rattan. The observation window, display screen, and pull rod design on the upper door, as well as the setting of the lower door, make it convenient for operators to monitor the test status at any time, perform necessary operations and maintenance, reduce the complexity and labor intensity of the operation process, and improve work efficiency.

[0006] Preferably, the illumination component includes an ultraviolet lamp cover, inside which is an ultraviolet light lamp. The ultraviolet light lamp is associated with a sample holder. A fan is located on one side of the ultraviolet lamp cover, and an insulation board is located on the other side. By providing specific ultraviolet irradiation conditions through the ultraviolet light lamp, combined with the fan promoting airflow and the insulation board maintaining temperature stability, the aging of plastic rattan under the combined effects of ultraviolet radiation and temperature in a real outdoor environment can be simulated more accurately. This makes the test results more representative and valuable, and helps to develop plastic rattan products with better aging resistance. The protection provided by the ultraviolet lamp cover avoids the safety hazards caused by ultraviolet leakage, while the heat insulation effect of the insulation board reduces energy consumption. This optimizes the safety and energy efficiency of the test device, meeting safety production requirements while reducing test costs and improving economic benefits.

[0007] Preferably, the sampling assembly includes a housing, inside which a sampling cylinder is located. One end of the sampling cylinder has a sampling seat, a probe seat is located on one side of the sampling seat, and a sampling probe is located above the probe seat. Through the precise drive of the sampling cylinder and the flexible adjustment of the probe seat in conjunction with the sampling probe, samples can be quickly and accurately collected from the chamber when needed. Whether it is a gas sample or other relevant samples, the efficiency of the sampling process and the representativeness of the samples are ensured. This provides a reliable sample guarantee for subsequent accurate analysis of environmental parameter changes during the aging process of plastic rattan, and helps to deepen the understanding of the relationship between plastic rattan aging and environmental factors. The housing protects the sampling components, making the sampling assembly less susceptible to damage during daily use. Furthermore, when a component (such as worn sampling probe) needs maintenance or replacement, the reasonable and well-organized structure allows for convenient and quick operation, reducing test interruption time caused by component repair or replacement, and improving the overall reliability and usability of the testing device.

[0008] Preferably, the lifting assembly includes two lifting cylinders, which are arranged correspondingly. A first connecting frame is provided on the top of each lifting cylinder, and connecting frame plates are provided on both sides of the first connecting frame. The connecting frame plates are associated with the ultraviolet lamp cover. This lifting assembly structure design allows for stable and precise adjustment of the distance between the ultraviolet lamp cover and the sample. This enables flexible changes in lighting conditions based on the different light intensity requirements of plastic rattan samples of different types, thicknesses, or testing stages, making the experiment more scientific and flexible. It also helps to obtain more accurate and comprehensive aging test data for plastic rattan. The design of the double lifting cylinders combined with the connecting frame plates enhances the stability of the entire lifting system and the related ultraviolet lamp cover, reducing the impact of vibrations and instability caused by lifting movements on the test environment and results. This ensures the smooth progress of the test process and improves the service life and reliability of the testing device.

[0009] Preferably, the insulation board is provided with slide rails on both sides, and a second connecting frame is provided at one end of the insulation board. The insulation board is associated with the ultraviolet lamp cover. The slide rails make the movement of the insulation board labor-saving and convenient. Operators can easily adjust the position of the insulation board according to the test requirements (such as moving it closer to or further away from the sample rack), so as to better achieve the temperature control of the plastic rattan aging test environment, meet the temperature requirements under different test scenarios, and improve the flexibility and operability of the test.

[0010] Preferably, the base has heat dissipation vents on both sides, a filter barrel inside the base, a water tank below the filter barrel, a partition plate on one side of the water tank, a chiller on one side of the partition plate, fan blades on one side of the chiller, and a fan protective cover on the outer wall of the fan blades. This facilitates maintenance and repair: the lower door makes maintenance and repair of the base's interior more convenient. When electrical wiring, piping systems, or other critical components inside the base malfunction or require periodic inspection, operators can directly open the lower door to perform the corresponding operations, greatly shortening repair time, reducing test interruptions due to equipment failure, and improving the overall operating efficiency and reliability of the testing device. The space inside the lower door can be used to store auxiliary items related to the test, such as spare test consumables and small tools, making the test site more tidy and orderly. It also allows operators to easily access necessary items during use, further optimizing the test workflow and improving the convenience and efficiency of test operations.

[0011] The advantages of this utility model are:

[0012] This application utilizes the coordinated operation of components such as an ultraviolet lamp cover, a cooling device, a heating device, and a humidifier to accurately simulate various key factors in the outdoor environment, including ultraviolet radiation, temperature changes, and humidity fluctuations. This makes the test environment closer to the actual use scenario of plastic rattan, thereby obtaining more accurate and reliable aging test data and providing a strong guarantee for evaluating the aging resistance of plastic rattan. The lifting assembly uses two corresponding lifting cylinders, along with the first connecting frame and connecting plate, to smoothly, vertically, and flexibly adjust the distance between the ultraviolet lamp cover and the sample. It can precisely control the light conditions according to the different light intensity requirements of plastic rattan samples of different types, thicknesses, or test stages, improving the scientific nature and flexibility of the test and helping to conduct in-depth research on the aging characteristics of plastic rattan under different light intensities. The insulation board is equipped with slide rails on both sides and limit blocks to restrict its movement range. This facilitates the adjustment of the insulation board's position, allowing for optimization of the insulation effect according to test requirements, while also ensuring its stability and safety during movement, preventing accidental detachment or displacement. Meanwhile, the lower door on one side of the base makes it more convenient to inspect, maintain, and store auxiliary items inside the base, greatly improving the daily operation and maintenance efficiency of the test device. The sampling components include a sampling cylinder, a sampling probe holder, a probe, and an adjustable height and angle probe holder, which can conveniently, quickly, and accurately collect samples from inside the test chamber. Whether it is a gas or liquid sample, it can meet the sampling needs during the test process, which helps to understand the changes in environmental parameters inside the chamber in a timely manner and provides data support for further analysis of the aging mechanism of plastic rattan.

Improving test accuracy: Through reasonable structural design, such as the top lighting component, internal sample rack 24, and good sealing (function of the plug 16), a relatively stable, uniform, and precisely controllable aging test environment can be created for plastic rattan. This allows the test results to more accurately reflect the aging of plastic rattan in actual use, which helps researchers to conduct in-depth research on the aging characteristics of plastic rattan and provides a reliable basis for improving the formulation and production process of plastic rattan. The design of the observation window 10, display screen 11, and pull rod 17 on the upper door 12, as well as the setting of the lower door 9, makes it convenient for operators to monitor the test status at any time, perform necessary operations and maintenance, reduce the complexity and labor intensity of the operation process, and improve work efficiency.

[0023] In this embodiment, the illumination component includes an ultraviolet lamp cover 3, inside which is an ultraviolet light lamp 18. The ultraviolet light lamp 18 is associated with the sample holder 24. A fan 5 is provided on one side of the ultraviolet lamp cover 3, and an insulation board 14 is provided on the other side. By providing specific ultraviolet irradiation conditions through the ultraviolet light lamp 18, combined with the fan 5 promoting airflow and the insulation board 14 maintaining temperature stability, the aging of plastic rattan under the combined effects of ultraviolet radiation and temperature in actual outdoor environments can be simulated more accurately. This makes the test results more representative and valuable for reference, and helps to develop plastic rattan products with better aging resistance. The protection provided by the ultraviolet lamp cover 3 avoids the safety hazards caused by ultraviolet leakage, while the heat insulation effect of the insulation board 14 reduces energy consumption. This optimizes the safety and energy efficiency of the test device, meeting safety production requirements while reducing test costs and improving economic benefits.

[0024] In this embodiment, the sampling component includes a housing 7, inside which is a sampling cylinder 22. One end of the sampling cylinder 22 has a sampling seat 19, and one side of the sampling seat 19 has a probe seat 21. A sampling probe 20 is positioned above the probe seat 21. Through the precise driving of the sampling cylinder 22 and the flexible adjustment of the probe seat 21 in conjunction with the sampling probe 20, samples can be quickly and accurately collected from inside the chamber 29 when needed. Whether it is a gas sample or other relevant samples, the efficiency of the sampling process and the representativeness of the samples are ensured. This provides a reliable sample guarantee for subsequent accurate analysis of environmental parameter changes during the aging process of plastic rattan, and helps to deepen the understanding of the relationship between plastic rattan aging and environmental factors. The protection provided by the housing 7 for the sampling components makes the sampling component less susceptible to damage during daily use. Furthermore, when a component (such as the worn sampling probe 20) needs maintenance or replacement, the reasonable and well-organized structure allows for convenient and quick operation, reducing test interruption time caused by component repair or replacement and improving the overall reliability and usability of the testing device.

[0025] In this embodiment, the lifting assembly includes two lifting cylinders 13, which are arranged correspondingly. A first connecting frame 1 is provided on the top of each lifting cylinder 13, and connecting frame plates 4 are provided on both sides of the first connecting frame 1. The connecting frame plates 4 are associated with the ultraviolet lamp cover 3. This lifting assembly structure design allows for stable and precise adjustment of the distance between the ultraviolet lamp cover 3 and the sample. This enables flexible changes in lighting conditions based on the different light intensity requirements of plastic rattan samples of different types, thicknesses, or test stages, making the test more scientific and flexible, and helping to obtain more accurate and comprehensive aging test data for plastic rattan. The design of the double lifting cylinders 13 in conjunction with the connecting frame plates enhances the stability of the entire lifting system and the related ultraviolet lamp cover 3, reducing the impact of vibrations and instability caused by lifting movements on the test environment and results, ensuring the smooth progress of the test process, and improving the service life and reliability of the test device.

[0026] In this embodiment, the insulation board 14 is provided with slide rails 15 on both sides, and a second connecting frame 2 is provided at one end of the insulation board 14. The insulation board 14 is associated with the ultraviolet lamp cover 3. The slide rails 15 make the movement of the insulation board 14 effortless and convenient. Operators can easily adjust the position of the insulation board 14 according to the test requirements (such as moving it closer to or further away from the sample rack 24), so as to better achieve the heat preservation control of the plastic rattan aging test environment, meet the heat preservation requirements under different test scenarios, and improve the flexibility and operability of the test.

[0027] In this embodiment, the base has heat dissipation vents 8 on both sides, a filter barrel 23 inside the base, a water tank 25 below the filter barrel 23, a partition plate on one side of the water tank 25, a chiller 28 on one side of the partition plate, a fan blade 27 on one side of the chiller 28, and a fan protective cover 26 on the outer wall of the fan blade 27. For ease of maintenance and repair: the lower door 9 makes maintenance and repair of the base's interior more convenient. When electrical wiring, piping systems, or other key components inside the base malfunction or require periodic inspection, operators can directly open the lower door 9 to perform the corresponding operations, greatly shortening maintenance time, reducing test interruption time due to equipment failure, and improving the overall operating efficiency and reliability of the test device. The space inside the lower door 9 can be used to store auxiliary items related to the test, such as spare test consumables and small tools, making the test site more organized and tidy. It also allows operators to easily access the required items during use, further optimizing the test workflow and improving the convenience and efficiency of test operations.

[0028] The implementation principle of this embodiment is as follows: First, the plastic rattan sample to be tested is placed and fixed on the sample rack 24 inside the test chamber. Then, according to the test requirements, the corresponding test parameters are set by operating the control system on the electrical control cabinet. The matching temperature and humidity sensors monitor the temperature and humidity inside the test chamber in real time and transmit the data to the control system. The ultraviolet lamp emits ultraviolet light of a specific wavelength range after being powered on, simulating the outdoor ultraviolet radiation environment to irradiate the plastic rattan sample and cause it to undergo an aging reaction. Next, when it is necessary to adjust the temperature inside the test chamber, if the set temperature is higher than the room temperature, the heating device will be activated to raise the temperature to the set temperature. The system operates by absorbing heat from the test chamber and releasing it to the outside through the coordinated action of components such as the chiller 28 and fan blades 27, thus lowering the temperature to the required value. When not in use or during insulation, the lifting cylinder 13 in the lifting assembly moves the ultraviolet lamp cover 3 vertically. Through the cooperation of two corresponding lifting cylinders 13, the first connecting frame 1, the connecting frame plate 4, the slide rail 15, and the second connecting frame 2, the insulation plate 14 covers the mounting slot of the ultraviolet lamp cover 3. Finally, when it is necessary to collect and analyze samples of gases, liquids, etc., inside the test chamber, the sampling assembly begins operation. The operator can control the extension and retraction of the sampling cylinder 22 to lower the sampling probe 20 to a suitable height, and then adjust the angle of the probe to accurately insert it into the desired sampling position. The collected samples can then be used for related testing and analysis.
