Description

Technical Field

[0001] This utility model belongs to the field of materials science and technology, specifically a humidity control device for detecting the hygroscopicity of fibers. Background Technology

[0002] Many fiber materials, especially synthetic fibers, have high strength and relatively light weight, making them ideal for applications where load-bearing capacity, strength, and portability are required. The hygroscopicity of fibers changes significantly with ambient humidity. By using humidity control devices, the humidity level in the test environment can be precisely adjusted and stably controlled, ensuring the accuracy and consistency of measurement results.

[0003] The principle of humidity control devices for fiber moisture absorption testing mainly involves two aspects: humidity control and airflow regulation. By applying precise humidity control and airflow regulation principles, these devices can efficiently regulate the humidity of the testing environment, providing strong support for fiber testing.

[0004] Existing humidity control devices often supply gas in a single direction from the output of the humidifier and dehumidifier during the humidity control process inside the testing chamber. When gas is supplied in a single direction for a long time, it will cause the humidity in one area to be too high and the humidity in another area to be too low, resulting in uneven distribution of humidity in the environment and affecting the final test results of fiber hygroscopicity. Therefore, a humidity control device for fiber hygroscopicity testing is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, existing humidity control devices often deliver gas in a single direction from the output of the humidifier and dehumidifier during the humidity control process inside the testing chamber. When gas is delivered in a single direction for a long time, it will cause the humidity in one area to be too high and the humidity in another area to be too low, resulting in uneven distribution of humidity in the environment and affecting the final test results of fiber hygroscopicity. This utility model proposes a humidity control device for fiber hygroscopicity testing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a humidity control device for testing the hygroscopicity of fibers, including a workbench. A testing chamber is fixedly installed on the top of the workbench. Multiple hinges are fixedly installed on the outer side of the testing chamber. A chamber door is fixedly installed on the outside of the hinges. A handle is fixedly installed on the outer side of the chamber door. A steam humidifier is fixedly installed at one end of the top of the testing chamber. A dehumidifier is fixedly installed at the other end of the top of the testing chamber. Fans are fixedly installed at all four ends of the top of the inner wall of the testing chamber. Telescopic hoses are fixedly installed at the output ends of the steam humidifier and the dehumidifier. A nozzle is fixedly installed at one end of the telescopic hose through the inside of the testing chamber. The telescopic hose is located inside the workbench. One end of the device has fixed plates on both sides. The tops of the multiple fixed plates are fixedly installed on the top of the inner wall of the detection chamber. Each of the multiple fixed plates has a groove on one side inside. An electric slide rail is fixedly installed inside the groove. A sliding block is slidably installed between the multiple electric slide rails. One end of the telescopic hose is located outside the sliding block. The electric slide rail drives the sliding block to move back and forth. When the sliding block moves back and forth, it drives one end of the telescopic hose inside to move. When one end of the telescopic hose moves, the nozzle delivers gas to different areas, achieving the effect of delivering gas to multiple locations. The delivered gas fills the inside of the detection chamber, making the fiber to be tested in a more uniform humidity environment and improving the accuracy of the final moisture absorption test.

[0007] Preferably, a support plate is fixedly installed at the top center of the workbench, and a weighing balance is fixedly installed at the top center of the support plate. Support columns are fixedly installed at all four ends of the top of the support plate. Springs are fixedly installed on the top inner wall of the support columns. A pressing block is fixedly installed on the outside of one end of the spring. The bottom of the pressing block is in close contact with the top of the weighing balance. Pressure is applied to the pressing block by the elasticity of the spring itself. When the pressing block is under pressure, it will move downward and finally fix the four ends of the fiber to be tested. After the fixing is completed, the fiber to be tested is weighed by the weighing balance to obtain the moisture absorption data of the fiber.

[0008] Preferably, a sealing ring is fixedly installed on the outer side of the chamber door, and an installation groove is provided on the inner side of the testing chamber. The outer side of the sealing ring is tightly attached to the inside of the installation groove. By tightly attaching the sealing ring to the inside of the installation groove, the airtightness of the testing chamber is improved, preventing gas leakage inside the testing chamber from causing errors in the final testing data.

[0009] Preferably, a humidity detector is fixedly installed on one side of the inner wall of the workbench. The detection end of the humidity detector is located inside the detection chamber. The humidity inside the detection chamber is detected by the humidity detector (model Li-Cor LI-250A). The humidity sensor adopts optical principles, such as using the specific absorption wavelength of water vapor to measure the change in the concentration of water vapor in the air. By calculating the absorption of light by water vapor, the humidity level can be indirectly calculated, which makes it convenient for the testing personnel to understand the humidity inside the detection chamber in real time.

[0010] Preferably, a control panel is fixedly installed on the outer side of the testing chamber. The control panel is electrically connected to a steam humidifier, a dehumidifier, an electric slide rail, a fan, a humidity detector, and a weighing balance. Multiple devices can be controlled through the control panel, making it convenient for testing personnel to operate the devices.

[0011] Preferably, a display screen is fixedly installed on the outer side of the control panel, and multiple control switches are provided below the display screen. The control switches are externally fixedly installed inside the control panel. The display screen displays the humidity data inside the detection chamber and the moisture absorption of the detection fiber by the weighing balance.

[0012] The advantages of this utility model are:

[0013] This invention addresses the problem of uneven humidity distribution in fiber hygroscopicity testing. By using a humidity control device to regulate the humidity of the testing environment during fiber hygroscopicity testing, an electric slide rail drives a sliding block to move back and forth. This movement of the sliding block moves one end of an internal telescopic hose, which then delivers gas to different areas. This achieves the effect of delivering gas to multiple locations, solving the problem that existing humidity control devices often deliver gas in a single direction during the humidity regulation process within the testing chamber. Prolonged single-direction gas delivery can lead to uneven humidity distribution, with some areas experiencing excessively high humidity and others too low, affecting the final fiber hygroscopicity test results. By filling the testing chamber with delivered gas, the fiber under test is placed in a more uniform humidity environment, improving the accuracy of the final hygroscopicity test.

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a humidity control device for testing the hygroscopicity of fibers includes a workbench 1. A testing chamber 2 is fixedly installed on the top of the workbench 1. Multiple hinges 6 are fixedly installed on one side of the outer side of the testing chamber 2. A chamber door 3 is fixedly installed on the outside of the hinges 6. A handle 7 is fixedly installed on one side of the outer side of the chamber door 3. A steam humidifier 4 is fixedly installed at one end of the top of the testing chamber 2. A dehumidifier 5 is fixedly installed at the other end of the top of the testing chamber 2. Fans 13 are fixedly installed at all four ends of the top of the inner wall of the testing chamber 2. The output ends of the steam humidifier 4 and the dehumidifier 5 are fixedly installed with... A telescopic hose 8 is provided, with one end of the telescopic hose 8 passing through the interior of the detection chamber 2 and a nozzle 12 fixedly installed thereon. Both sides of the end of the telescopic hose 8 located inside the workbench 1 are equipped with fixing plates 9. The tops of multiple fixing plates 9 are fixedly installed on the top of the inner wall of the detection chamber 2. A sliding groove is formed on one side of each fixing plate 9, and an electric slide rail 10 is fixedly installed inside the groove. A sliding block 11 is slidably installed between the multiple electric slide rails 10. One end of the telescopic hose 8 is located outside the sliding block 11. During operation, the existing humidity control device regulates the humidity of the detection environment. During humidity control, the fixed connection of the air outlet in the control device causes the gas to be continuously transported in one direction. To make the humidity control device more uniform in regulating the detection environment, the device activates the steam humidifier 4 and the dehumidifier 5 to humidify and dehumidify the moisture inside the detection chamber 2 to achieve the target humidity. During the humidity control process, the electric slide rail 10 drives the sliding block 11 to move. When the sliding block 11 moves, it drives the internally connected telescopic hose 8 to move. When the telescopic hose 8 moves, it drives the nozzle 12 to move. The telescopic hose 8 diffuses the gas transported by the steam humidifier 4 and the dehumidifier 5, so that it is output to a wider area inside the detection chamber 2. The sliding block 11 drives the telescopic hose 8 to move back and forth, and at the same time, it drives the nozzle 12 to move back and forth. The back and forth movement of the nozzle 12 achieves the effect of humidifying or dehumidifying different areas. Multiple fans 13 located at the top of the inner wall of the detection chamber 2 can transport the gas inside the detection chamber 2, so that it fills the detection chamber 2 more quickly and prevents the gas from accumulating inside the detection chamber 2.

[0023] A support plate 15 is fixedly installed at the top center of the workbench 1. A weighing balance 16 is fixedly installed at the top center of the support plate 15. Support columns 17 are fixedly installed at all four ends of the top of the support plate 15. Springs 18 are fixedly installed on the top of the inner wall of the support columns 17. A pressing block 19 is fixedly installed on the outside of one end of the spring 18. The bottom of the pressing block 19 is tightly attached to the top of the weighing balance 16. During operation, the existing humidity control device has the problem that the air outlet of the control device is fixedly connected, causing the gas to be transported in one direction when controlling the humidity of the detection environment. In order to make the humidity control device more uniform when controlling the detection environment, the device uses the elasticity of the spring 18 to drive multiple pressing blocks 19 to fix the four ends of the fiber above the weighing balance 16, which facilitates the detection.

[0024] A sealing ring 20 is fixedly installed on the outer side of the door 3, and an installation groove 21 is opened on the inner side of the detection chamber 2. The outer side of the sealing ring 20 is tightly attached to the inside of the installation groove 21. During operation, the existing humidity control device has the problem that the air outlet of the control device is fixedly connected, causing the gas to be transported in one direction when controlling the humidity of the detection environment. In order to make the humidity control device more uniform when controlling the detection environment, the sealing ring 20 is connected to the installation groove 21 to improve the airtightness of the connection between the door 3 and the detection chamber 2 and prevent internal leakage.

[0025] A humidity detector 14 is fixedly installed on one side of the inner wall of the workbench 1. The detection end of the humidity detector 14 is located inside the detection chamber 2. During operation, the existing humidity control device has a problem that the air outlet of the control device is fixedly connected, causing the gas to be transported in one direction during humidity control. In order to make the humidity control device more uniform when controlling the detection environment, this device uses the humidity detector 14 to detect the humidity inside the detection chamber 2, so as to understand the humidity situation inside the detection chamber 2.

[0026] A control panel 22 is fixedly installed on the outer side of the detection chamber 2. The control panel 22 is electrically connected to the steam humidifier 4, the dehumidifier 5, the electric slide rail 10, the fan 13, the humidity detector 14, and the weighing balance 16. During operation, the existing humidity control device has the problem that the air outlet of the control device is fixed, causing the gas to be transported in one direction when controlling the humidity of the detection environment. In order to make the humidity control device more uniform when controlling the detection environment, the control panel 22 controls the steam humidifier 4, the dehumidifier 5, the fan 13, the humidity detector 14, and the weighing balance 16, which is convenient for operators to use quickly.

[0027] A display screen 23 is fixedly installed on the outer side of the control panel 22. Multiple control switches 24 are located below the display screen 23. The control switches 24 are fixedly installed inside the control panel 22. During operation, existing humidity control devices have a problem where the air outlet is fixedly connected, causing the gas to be transported in one direction during humidity control. In order to make the humidity control device more uniform in regulating the detection environment, this device displays the detection data on the display screen 23, while the control switches 24 can activate different functions of the entire device.

[0028] The working principle is as follows: During the fiber hygroscopicity test, a humidity control device is used to regulate the humidity of the testing environment. First, the fiber to be tested is placed above the weighing balance 16. Then, pressing blocks 19 connected to multiple springs 18 fix the four ends of the fiber. At this time, the springs 18 are under pressure. After the four ends of the fiber are fixed, the steam humidifier 4 (Vornado Evaporative Humidifiers) and the dehumidifier 5 (MEACO) are activated via the control panel 22 to humidify and dehumidify the moisture inside the testing chamber 2 to achieve the target humidity. During humidity control, the electric slide rail 10 drives the sliding block 11 to move. When the sliding block 11 moves, it drives the internally connected telescopic hose 8 to move. When the telescopic hose 8 moves, it drives the nozzle 12 to move. The telescopic hose 8 diffuses the gas supplied by the steam humidifier 4 and the dehumidifier 5, allowing it to be output to a wider area inside the testing chamber 2. Block 11 moves the telescopic hose 8 back and forth, which in turn moves the nozzle 12 back and forth. The movement of the nozzle 12 back and forth achieves the effect of humidification or dehumidification in different areas. Multiple fans 13 located on the top of the inner wall of the detection chamber 2 can transport the gas inside the detection chamber 2, so that it fills the detection chamber 2 more quickly and prevents the gas from accumulating inside the detection chamber 2. When the humidity inside the detection chamber 2 is uniform, it is left idle for a period of time to test the fiber. After that, the weight change of the weighing balance 16 is observed through the display screen 23 installed on the outside of the control panel 22 to obtain the data of fiber hygroscopicity.
