It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-2 As shown, a multi-station weighing method moisture permeability structure device includes a centrifugal impeller 1, a brushless motor output shaft 2 is provided at the bottom of the centrifugal impeller 1, a moisture permeable cup 3 is provided on one side of the brushless motor output shaft 2, a cavity bottom plate 4 is provided at the bottom of the moisture permeable cup 3, a bearing 5 is provided at the bottom of the cavity bottom plate 4, a synchronous pulley 6 is provided at the bottom of the bearing 5, a guide rail 7 is provided on one side of the synchronous pulley 6, a slip ring 8 is provided at the bottom of the guide rail 7, an encoder 9 is provided at the bottom of the slip ring 8, a motor 10 is provided on one side of the encoder 9, and a lifting cylinder 11 is provided on one side of the motor 10.

[0021] The centrifugal impeller 1 accelerates air through its blades and discharges it outward, creating a uniform airflow. This provides a stable air speed, effectively controlling the airflow conditions during the moisture permeability test, thereby improving the accuracy and repeatability of the test results. A brushless motor output shaft 2 is located at the bottom of the centrifugal impeller 1. This shaft transmits the rotational power generated by the motor 10 to the centrifugal impeller 1. A moisture permeability cup 3 is located on one side of the brushless motor output shaft 2 to measure the moisture permeability of the material. Through the moisture permeability cup 3, the sample is fully exposed to the airflow generated by the centrifugal impeller 1, allowing for an accurate assessment of water vapor transmission and the material's moisture permeability coefficient. A moisture permeability cup base 12 is located on one side of the moisture permeability cup 3, connecting the brushless motor output shaft 2 and the moisture permeability cup 3. This base 12 provides support for the moisture permeability cup 3, increasing its stability and ensuring it remains in place during the test.

[0022] The permeable cup 3 is provided with a cavity floor 4 at its base, providing stable support for the device. This floor 4 also ensures the stability and sealing of the entire device, preventing external air from interfering with the test environment, thereby ensuring the accuracy of the moisture permeability test. A bearing 5 is located at the bottom of the cavity floor 4. Bearing 5 supports the rotating components within the device and contains spherical balls. These reduce friction and wear during rotation, thereby improving the device's operating efficiency and service life while maintaining accuracy during testing. A brushless motor mounting base 13 is located at the bottom of the bearing 5. This mounting base houses a brushless motor 14, ensuring stability during operation. The annular design of the brushless motor mounting base 13 reduces the impact of vibration on test results. The brushless motor 14 is housed within the mounting base 13. The extended shaft of the brushless motor 14 passes through the bearing 5 and enters the cavity, connecting to the centrifugal impeller 1 within the cavity, thereby enabling controllable wind speed within the cavity. A weighing mechanism 15 is provided on one side of the bearing 5. The weighing mechanism 15 is used to monitor and record the weight change of the sample in the moisture permeable cup 3 in real time. By measuring the weight change of the sample, the staff can calculate the moisture permeability of the material, thereby evaluating the performance and quality of the material.

[0023] A synchronous pulley 6 is installed at the bottom of the bearing 5. This pulley is used to transmit power and control the direction of movement. A synchronous belt 16 is installed on one side of the synchronous pulley 6. This belt is connected to the synchronous pulley 6 and is responsible for connecting the motor 10 and the weighing mechanism 15, transmitting power, maintaining a stable transmission ratio, and achieving precise displacement control. A guide rail 7 is installed on one side of the synchronous pulley 6. This guide rail 7 ensures smooth movement of the various moving parts and reduces friction. A slip ring 8 is installed at the bottom of the guide rail 7. This slip ring 8 transmits electrical signals. This ensures stable signal transmission between the motor 10 and the rotating device. An encoder 9 is installed at the bottom of the slip ring 8. This encoder 9 is used to monitor and provide real-time feedback on the position of the moisture permeable cup 3. A motor 10 is installed on one side of the encoder 9. This motor drives the various moving parts. A lifting cylinder 11 is installed on one side of the motor 10. This lifting cylinder 11 is used to achieve vertical movement of the lifting mechanism. Two sliders 8 are installed on one side of the guide rail 7. These sliders are moving components that work with the guide rail 7. The slider 8 is responsible for carrying and guiding the movement of the synchronous pulley 6 .
