Description

Textile temperature and humidity control air homogenizing system

Technical Field

The invention relates to the technical field of test instruments, in particular to a textile temperature and humidity control air homogenizing system.

Background

The fabric moisture permeability test is to place a test cup filled with a drying agent and sealed with a fabric sample on a test disc in a sealed environment with specified temperature and humidity, and to flow a wind current with a certain speed on the upper surface of the sample, and then calculate the moisture permeability, moisture permeability and moisture permeability coefficient of the sample according to the change of the quality of the moisture permeable cup in a certain time. In general, an instrument used for testing the moisture permeability of the fabric is a textile temperature and humidity control air homogenizing system.

The textile temperature and humidity control air homogenizing system mainly comprises a temperature and humidity generating system, an air flow homogenizing system, a control system and a system pipeline. The wind flow homogenizing and dividing system mainly provides uniform wind flows of different grades for the instrument, so that the instrument is suitable for wind flow speed requirements of different standards of different countries. Meanwhile, the eight test cups placed on the test disc can obtain uniform and stable wind flow speed.

Traditional wind flow systems are of right-to-left structural design. In the structure, when the structure is used for testing, the wind flow actually received by the eight test cups has a certain gradient, and the wind flow speed received by the test cups is not uniform enough. That is, the wind flow rate gradually decreases from right to left, so that the final data result measured by the eight test cups is different. It is clear that in theory, the more uniform, the closer and better the moisture permeability results should be measured on an even sample over eight test cups.

Detailed Description

Examples, see fig. 1: the textile temperature and humidity control air homogenizing system comprises an inner cylinder body 10. The inner cylinder 10 is internally provided with a horizontal tray 30, and a plurality of test cups 70 are placed on the trays 30. As shown in fig. 2, the test cup 70 may include a cup 71, a sealing ring 72 and a pressing ring 73 are disposed at an edge of an opening at an upper portion of the cup 71, an edge of a sample may be pressed between the sealing ring 72 and the pressing ring 73, and a desiccant 74 is disposed in the cup 71.

Further speaking:

the top center of the inner cylinder 10 is provided with a vertical rotary cylinder 20. The rotary drum 20 and the inner drum 10 preferably have the same vertical axis. The rotary drum 20 is in power connection with a driving motor 40, and the lower part of the rotary drum 20 is positioned inside the inner drum 10. The trays 30 are coaxially fixed to the rotary tube 20. Meanwhile, a blowing hole 21 is provided on the sidewall of the rotary pipe 20, and the lower end of the rotary pipe 20 is connected to an air outlet of a fan 80. The side wall of the inner cylinder 10 is provided with an air return port 11. And an outer cylinder 12 is arranged outside the inner cylinder 10 in a sealing way, and the return air inlet 11 is communicated with an air inlet of the fan 80. By sealed arrangement, it is meant that the outer barrel 12 is a sealed barrel. Preferably, the air inlet of the fan 80 is connected to the gap between the inner cylinder 10 and the outer cylinder 12. The blower 80 may be fixed to the lower sidewall of the inner cylinder 10. Thus, after the fan 80 is operated, wind enters the rotary pipe 20, is blown out from the wind blowing holes 21, flows through the test cups 70 on the trays 30, and finally flows into the fan 80 again through the return air inlet 11. Obviously, the uniformity of the wind received by the test cup 70 is greatly improved compared to a single wind direction of a conventional tester.

Optimizing:

the top of the inner cylinder 10 is provided with a planar bearing 50. The upper portion of the rotary drum 20 is supported on the planar bearing 50. Of course, a planar bearing may be provided at the lower portion of the rotary drum 20. In this way, the rotation of the rotary drum 20 is smoother. The drive motor 40 is preferably fixed to the top of the inner cylinder 10 so that the structure tends to be compact.

Continuing to optimize:

a lifting adjusting device 60 is fixed on the top of the outer cylinder 12. The elevation adjustment device 60 is connected to an adjustment platen 64. At the same time, the rotary drum 20 has an upper opening 22, and the pressure regulating plate 64 is fitted to the upper opening 22. That is, the pressure adjusting plate 64 can be lifted by the lifting adjusting device 60, so that it can be completely covered on the upper opening 22, or the opening size of the upper opening 22 can be adjusted after being moved upward. Thus, the air volume flowing through the air outlet 21 can be adjusted, and the air volume flowing through the test cups 70 can be adjusted.

The elevation adjustment means 60 may be provided in various common manners such as a cylinder. In this embodiment, the elevation adjustment apparatus 60 includes: a lifting motor 61 fixed on the top of the outer cylinder 12, a screw 62 connected to the power output shaft of the lifting motor 61, and a nut 63 fixed on the pressure adjusting plate 64 and matched with the screw 62. Obviously, the pressure regulating disc 64 is movable up and down but is not rotatable. In this way, the lift adjustment device 60 is formed by using the screw nut mechanism, and fine adjustment can be achieved.
