Description

Technical Field

[0001] This application relates to the field of textile drying rate monitoring technology, and in particular to an airflow drying rate tester. Background Technology

[0002] A drying tester is an important piece of equipment used to test the drying performance of fabrics. Its main function is to simulate and evaluate the drying conditions that fabrics experience during actual use or production. Drying performance refers to the rate of moisture evaporation from a fabric under specific conditions and its ability to absorb and release moisture. Testing the drying performance of fabrics is crucial for the textile industry because it directly affects the production efficiency, quality control, and subsequent performance of textiles.

[0003] Currently, textile drying testers are widely used in the textile industry to simulate the drying performance of textiles under different conditions. These test instruments typically consist of a fixing device used to secure the fabric to be tested on a test platform. An air vent and a bellows are located at the bottom of the fabric. A fan inside the bellows draws air through the fabric, simulating the actual drying process. By precisely controlling the temperature and humidity of the airflow, these devices can simulate the drying conditions of fabrics under different environments, providing data on the fabric's drying rate and final moisture content, and are widely used in quality control and production line optimization.

[0004] However, existing drying rate testers still have some problems in practical applications. Due to the downward airflow through the sample during testing, different samples will exhibit varying degrees of downward deformation (dentation). The drip needle cannot reliably contact the sample surface, and the water injection fails to make contact with the sample surface, instead falling as droplets, causing detection errors. Different fabrics will cause various different errors, and the testing instrument cannot guarantee that all fabric samples can be accurately tested under the same conditions, resulting in unreliability and poor repeatability. Therefore, a drying rate tester that can guarantee that all fabric samples can be tested under the same conditions is needed to solve the above problems. Utility Model Content

[0005] Therefore, it is necessary to provide a detector that can be tested under the same variables to solve the above problems.

[0006] An embodiment of this application provides an airflow drying rate tester, including a base and a support frame disposed on the base, the tester further including:

[0007] The detection mechanism includes a motor and a detection component mounted on the motor. The motor is mounted on the support frame, and the end of the detection component facing away from the motor is opposite to the fabric.

[0008] The water injection assembly includes a cylinder, a fixing plate, and a water injection component. The fixing plate is disposed on the detection assembly and fixes the cylinder and the water injection component respectively. The cylinder is used to control the movement of the water injection component.

[0009] The cylinder pushes the water injection component, and the motor drives the detection component and the water injection component to move. When the water injection component comes into contact with the fabric, the water injection component generates a contact force, which is transmitted to the detection component. The motor stops moving, and the water injection component begins to inject water.

[0010] In at least one embodiment of this application, the detection component includes a temperature sensor and a pressure sensor disposed on the temperature sensor, the pressure sensor is disposed on the motor, and the fixing plate is fixedly connected to the pressure sensor;

[0011] The testing instrument also includes a control component electrically connected to the pressure sensor and the motor. The water injection component abuts against the fabric to generate a contact force that is transmitted to the pressure sensor. The control component controls the motor to stop moving in order to fix the distance between the detection component and the fabric.

[0012] In at least one embodiment of this application, the detection component includes a housing arranged in a vertical direction and a temperature sensor disposed on the housing, and the pressure sensor is fixedly connected to the motor and the housing at opposite ends, respectively.

[0013] The fixed housing includes a first fixing part and a second fixing part that are fixedly connected in sequence. The first fixing part has a fixing groove, and the second fixing part has a positioning hole facing the fixing groove. The temperature sensor is located in the fixing groove and partially extends out of the positioning hole. The second fixing part fixes the temperature sensor.

[0014] In at least one embodiment of this application, the tester further includes a fixing frame disposed between the motor and the detection component, the pressure sensor disposed on the fixing frame, and the output end of the motor fixedly connected to the fixing frame for driving the synchronous movement of the detection mechanism and the water injection component.

[0015] In at least one embodiment of this application, the detection mechanism further includes a sliding component;

[0016] The sliding assembly includes a slide rail and a slider that is slidably connected to the slide rail. The slide rail is arranged in a vertical direction and one end is fixedly connected to the support frame. The end of the slider away from the slide rail is fixedly connected to the fixed frame.

[0017] In at least one embodiment of this application, the water injection assembly further includes a connecting block, a water inlet hole is provided on one side of the connecting block, the water injection component is disposed in the water inlet hole, the output end of the cylinder is fixedly connected to the other side of the connecting block, and the water injection assembly is inclined in the vertical direction.

[0018] In at least one embodiment of this application, the tilting direction of the water injection component is defined as a first direction, and when the cylinder pushes the water injection component against the fabric along the first direction, the projection of the water injection port along the vertical direction is directly opposite the temperature sensor.

[0019] In at least one embodiment of this application, the tester further includes a lifting assembly, which is located on the side of the support frame away from the testing mechanism and is used to drive the entire support frame to move in a vertical direction.

[0020] In at least one embodiment of this application, the tester further includes a photoelectric origin switch, which is disposed on the support frame and used for resetting the tester.

[0021] The aforementioned airflow drying rate tester connects a water injection component to a pressure sensor. A cylinder pushes the water injection component to maintain a fixed distance between it and the detection component. Simultaneously, a motor drives both the detection and water injection components downwards. The water injection component, upon contacting the fabric, generates a contact force that acts in the opposite direction on the detection component. Upon detecting this contact force, the motor stops, and the water injection component begins injecting water into the fabric. Since different fabrics develop varying degrees of indentation under airflow, the water injection component of this application can form a stable contact with the fabric surface before water injection. Regardless of the degree of indentation, this ensures that the water injection process is completed through direct contact with the fabric surface. This effectively avoids detection errors caused by falling water droplets, improving the accuracy and reliability of the test. Attached Figure Description

Detailed Implementation

[0029] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0031] An embodiment of this application provides an airflow drying rate tester, including a base and a support frame disposed on the base, the tester further including:

[0032] The detection mechanism includes a motor and a detection component mounted on the motor. The motor is located at one end of the support frame away from the base. The detection component is used to detect the drying rate of the fabric.

[0033] The water injection assembly includes a cylinder, a fixing plate, and a water injection component. The fixing plate is mounted on the detection assembly, and the cylinder is located at the end of the water injection component opposite to the water outlet and is fixedly connected to the fixing plate.

[0034] The detection mechanism further includes a pressure sensor mounted on the detection assembly, and a fixing plate mounted on the pressure sensor. When the cylinder pushes the water injection component to move, the water injection component abuts against the fabric to generate a contact force, which is transmitted to the pressure sensor. The water injection component then stops moving and begins to inject water.

[0035] The aforementioned airflow drying rate tester connects a water injection component to a pressure sensor. When a cylinder pushes the water injection component to move, the component contacts the fabric, generating a contact force that acts in the opposite direction on the pressure sensor. The pressure sensor detects this contact force, the cylinder stops moving, and the water injection component begins injecting water into the fabric. Since different fabrics will develop varying degrees of indentation under airflow, the water injection component of this application can form a stable contact with the fabric surface before water injection. Regardless of the degree of fabric indentation, it ensures that the water injection process is completed through direct contact with the fabric surface. This effectively avoids detection errors caused by falling water droplets, improving the accuracy and reliability of the test.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Please see Figures 1-5 An embodiment of this application provides an airflow drying rate tester 100, including a base and a support frame 60 disposed on the base. The tester further includes:

[0038] The detection mechanism 10 includes a motor 11 and a detection component 12 disposed on the motor 11. The motor 11 is disposed on the support frame 60, and the end of the detection component 12 facing away from the motor 11 is facing the fabric.

[0039] The water injection assembly 20 includes a cylinder, a fixing plate 22, and a water injection component 23. The fixing plate 22 is disposed on the detection assembly 12. The fixing plate 22 fixes the cylinder and the water injection component 23 respectively. The cylinder is used to control the movement of the water injection component 23.

[0040] The cylinder pushes the water injection component 23, and the motor 11 drives the detection component 12 and the water injection component 20 to move. When the water injection component 23 comes into contact with the fabric, the water injection component 23 generates a contact force, which is transmitted to the detection component 12. The motor 11 stops moving, and the water injection component 23 begins to inject water.

[0041] Specifically, motor 11 serves as the power source for the detection mechanism 10. Mounted on the support frame 60, motor 11 drives the movement of the entire detection assembly 12. The precise control capability of motor 11 ensures that the detection assembly 12 can move smoothly and accurately to the designated position. The detection assembly 12 is mounted on motor 11, with one end facing away from motor 11 and towards the fabric. Detection assembly 12 includes sensors or other detection elements. When the water injection component 23 contacts the fabric, the detection assembly 12 senses the contact force and transmits a signal to the control system to control the stopping of motor 11 and the water injection operation of the water injection component 23. The water injection component 23 simulates the wet state in actual use.

[0042] Furthermore, the cylinder is responsible for pushing the water injection component 23 to a preset position, ensuring that the relative distance between the water injection component 23 and the detection component 12 remains constant. The precise control capability of the cylinder ensures that the water injection component 23 can reach the designated position smoothly and accurately. This achieves precise control over the position of the water injection component 23, avoiding test errors caused by inaccurate positioning. At the same time, it ensures the stability of the relative position between the water injection component 23 and the detection component 12, improving the accuracy of the test.

[0043] Next, the fabric is placed on the base, and the bottom of the testing instrument is clamped to the base to secure the fabric. The cylinder then activates, pushing the water injection component 23 to a preset position. At this point, the motor 11 begins to drive the entire detection assembly 12 and the water injection assembly 20 downwards. When the water injection component 23 contacts the fabric, a contact force is generated, and this signal is transmitted to the control system through the detection component. Upon receiving the signal from the detection component, the control system immediately stops the movement of the motor 11. At this point, the water injection component 23 maintains a stable contact with the fabric. The water injection component 23 then begins to inject water into the fabric. After water injection is completed, the cylinder retracts the dripping needle, avoiding the central area of ​​the sample, leaving the detection assembly 12 to test the sample drying rate.

[0044] In one specific embodiment, the detection component 12 includes a temperature sensor 122 and a pressure sensor 13 disposed on the temperature sensor 122, the pressure sensor 13 is disposed on the motor 11, and the fixing plate 22 is fixedly connected to the pressure sensor 13;

[0045] The tester also includes a control component 30 (not shown) electrically connected to the pressure sensor 13 and the motor 11. The water injection component 23 abuts against the fabric to generate contact force which is transmitted to the pressure sensor 13. The control component 30 controls the motor 11 to stop moving in order to fix the distance between the detection component 12 and the fabric.

[0046] Specifically, the control component, acting as the core brain of the tester, is responsible for receiving signals from various sensors, processing them according to preset logic and algorithms, and then sending control commands to each actuator. The control component is electrically connected to the pressure sensor 13, cylinder 21, and motor 11, ensuring that it can acquire data from the pressure sensor 13 in real time and precisely control the actions of the cylinder 21 and motor 11. This integrated design improves the automation level and response speed of the tester. When the water injection component 23 comes into contact with the fabric, the pressure sensor 13 can detect the contact force in real time and transmit this information to the control component. This ensures that the tester can accurately sense the contact state between the water injection component 23 and the fabric, thereby avoiding test errors caused by poor or no contact and improving the accuracy and reliability of the test.

[0047] In one specific embodiment, the detection component 12 further includes a housing 121, and the side of the pressure sensor 13 facing away from the motor 11 is fixedly connected to the housing 121;

[0048] The fixed housing 121 includes a first fixing part 121a and a second fixing part 121b that are fixedly connected in sequence. The first fixing part 121a has a fixing groove 121c, and the second fixing part 121b has a positioning hole 121d that faces the fixing groove 121c. The temperature sensor is located in the fixing groove 121c and partially extends out of the positioning hole 121d. The second fixing part 121b fixes the temperature sensor 122.

[0049] Specifically, the housing 121, arranged vertically, is the main structure of the detection assembly 12, providing protection and support for internal components such as the temperature sensor 122. The design of the housing 121 ensures the stability and durability of the detection assembly 12. The temperature sensor 122 is the core component of the detection assembly 12, used to monitor the temperature changes of the fabric in real time. It can accurately acquire temperature change data of the fabric during the drying process. The fixed connection between the pressure sensor 13 and the housing 121 also provides stable support for the pressure sensor 13, avoiding measurement errors caused by vibration or movement.

[0050] Furthermore, the mounting housing 121 is composed of a first fixing part 121a and a second fixing part 121b that are fixedly connected in sequence. This segmented design facilitates the installation and fixing of the temperature sensor 122, while also improving the flexibility and adaptability of the mounting housing 121. The fixing groove 121c on the first fixing part 121a is used to accommodate the temperature sensor 122, while the positioning hole 121d on the second fixing part 121b, which is opposite to the fixing groove 121c, is used to fix part of the protruding portion of the temperature sensor 122. This design ensures that the temperature sensor 122 can be stably fixed on the mounting housing 121, while avoiding measurement errors caused by movement or vibration.

[0051] In one specific embodiment, the tester further includes a fixing frame 40, which is disposed between the motor 11 and the detection component 12. The pressure sensor 13 is disposed on the fixing frame 40. The output end of the motor 11 is fixedly connected to the fixing frame 40 and is used to drive the synchronous movement of the detection mechanism 10 and the water injection component 20.

[0052] Specifically, the mounting bracket 40 is located between the motor 11 and the detection component 12, serving as a connection and support. The pressure sensor 13 is mounted on the mounting bracket 40, enabling it to accurately detect the contact force between the water injection component 20 and the fabric. By integrating the pressure sensor 13 with the mounting bracket 40, the measurement of the contact force is ensured to be more stable and accurate during testing. The output end of the motor 11 is fixedly connected to the mounting bracket 40, ensuring that the motor 11 can directly drive the mounting bracket 40 and its mounted detection component 12 and water injection component 20 to move synchronously. This design simplifies the structure of the tester and improves the accuracy and stability of the test.

[0053] In one specific embodiment, the detection mechanism 10 further includes a sliding component 50;

[0054] The sliding assembly 50 includes a slide rail 51 and a slider 52 slidably connected to the slide rail 51. The slide rail 51 is arranged in a vertical direction and one end is fixedly connected to the support frame 60. The end of the slider 52 away from the slide rail 51 is fixedly connected to the fixing frame 40.

[0055] Specifically, the sliding assembly 50 is an important component of the detection mechanism 10, enabling the smooth vertical movement of the detection assembly 12 (including the fixed frame 40 and its pressure sensor 13, water injection assembly 20, etc.). The design of the sliding assembly 50 ensures the flexibility and accuracy of the detection process. The slide rail 51 is the fixed part of the sliding assembly 50, set vertically to provide a stable track for the slider 52. One end of the slide rail 51 is fixedly connected to the support frame 60, ensuring the stability and positional accuracy of the slide rail 51.

[0056] Furthermore, the slider 52 is the moving part of the sliding assembly 50. It is slidably connected to the slide rail 51 and can move smoothly on the slide rail 51. The end of the slider 52 away from the slide rail 51 is fixedly connected to the fixing frame 40. Thus, when the slider 52 moves on the slide rail 51, the fixing frame 40 and the detection assembly 12 on it will also move accordingly. The slide rail 51, which is arranged vertically, ensures that when the motor 11 is driven, it can only move along the predetermined path of the slide rail 51. When monitoring different fabrics, it can prevent the detection assembly 12 from deviating and causing detection errors.

[0057] In one specific embodiment, the water injection assembly 20 further includes a connecting block 24, a water inlet hole 241 is provided on one side of the connecting block 24, the water injection component 23 is disposed in the water inlet hole 241, the output end of the cylinder 21 is fixedly connected to the other side of the connecting block 24, and the water injection assembly 20 is inclined in the vertical direction.

[0058] Specifically, the connecting block 24 is a key component of the water injection assembly 20, serving both a connecting and supporting function. A water inlet 241 is provided on one side of the connecting block 24, providing an installation position for the water injection component 23 and also a connection point for the output end of the cylinder 21. The water injection assembly 20 is inclined vertically; this design helps optimize the liquid spraying effect and coverage. The inclined water injection assembly 20 allows the liquid to have a certain angle and speed during spraying, thus better penetrating the fabric fibers.

[0059] In one specific embodiment, the tilting direction of the water injection component 20 is defined as the first direction. When the cylinder 21 pushes the water injection component 23 against the fabric along the first direction, the projection of the water injection port along the vertical direction is directly opposite the temperature sensor 122.

[0060] Specifically, the tilt direction of the water injection component 20 ensures that the sprayed liquid can cover the fabric at a certain angle, optimizing the spraying effect and coverage area. The vertical projection of the water injection nozzle directly faces the temperature sensor 122, ensuring that when the water injection component 23 comes into contact with the fabric, the vertical projection of the nozzle points precisely at the temperature sensor 122. Since the temperature sensor 122 is located above the water injection nozzle and maintains a fixed distance from the fabric, it can accurately measure the temperature change during liquid evaporation, thus reflecting the fabric's drying rate.

[0061] Furthermore, because the temperature sensor 122 is located above the water inlet and maintains a fixed distance from the fabric, it can accurately measure the temperature change caused by liquid evaporation, thereby accurately reflecting the drying rate of the fabric. This design reduces measurement errors caused by changes in distance or unstable contact. By ensuring a fixed distance between the temperature sensor 122 and the fabric, and stable contact between the liquid and the temperature sensor 122, this design guarantees a uniform variable in the test, improving the reliability and comparability of the test results.

[0062] In one specific embodiment, the tester further includes a lifting assembly 70, which is located on the side of the support frame 60 away from the detection mechanism 10, and is used to drive the support frame 60 to move vertically as a whole.

[0063] Specifically, this component is located on the side of the support frame 60 opposite to the detection mechanism 10, and its main function is to drive the support frame 60 to move vertically. The support frame 60 is the main structure of the tester, supporting key components such as the detection mechanism 10, the water injection component 20, and the cylinder 21. This component can drive the support frame 60 to move up and down vertically, and the height of the entire tester can be adjusted.

[0064] Furthermore, the introduction of the lifting assembly 70 allows the tester to adapt to testing needs at different heights. Whether on a laboratory bench or at different heights on the production line, the applicability and accuracy of the tester can be ensured by adjusting the lifting assembly 70. By adjusting the height of the support frame 60, the fabric can be placed more easily at the testing position, while ensuring that the detection mechanisms 10, such as the temperature sensor 122, can test the fabric at the correct distance and angle. This improves the flexibility and operability of the testing.

[0065] In one specific embodiment, the tester further includes an origin switch 80, which is disposed on the support frame 60 and is used for resetting the tester.

[0066] Specifically, by using the origin switch 80 to achieve reset and positioning, the tester is ensured to be in the same position and state before each test, thereby eliminating test errors caused by position changes and improving test accuracy and reliability. In continuous or multiple tests, the origin switch 80 allows the tester to quickly and accurately return to the starting position, saving test time and improving test efficiency. The introduction of the origin switch 80 simplifies the operation of the tester, eliminating the need for manual adjustment of the tester's position; simply triggering the origin switch 80 completes the reset operation.

[0067] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
