Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cotton fiber detection equipment, in particular to a micronaire value tester for cotton fiber textile production. Background Art
[0002] Micronaire value is a comprehensive index reflecting the fineness and maturity of cotton fiber. It is one of the important internal quality indicators of cotton fiber and is closely related to the use value of cotton fiber. The Micronaire value is divided into three levels: A, B, and C, with B being the standard level. The value range of A is 3.7-4.2, with the best quality; the value range of B is 3.5-3.6 and 4.3-4.9; the value range of C is 3.4 and below and 5.0 and above, with the worst quality. In order to facilitate the detection of the quality of cotton fiber, the Micronaire value meter will be used to detect the quality of cotton fiber.
[0003] When the Micronaire value meter is used to test cotton fibers, the cotton fibers are placed inside the Micronaire value meter. The Micronaire value meter uses an extrusion device to apply a specific pressure to the cotton fibers for extrusion. At the same time, high-pressure gas is introduced into both ends of the detection device, and a differential pressure gauge is used to detect the pressure difference inside the detection device. Thus, the quality of the cotton fibers can be tested. However, when the detection device is used to extrude the cotton fibers, the extrusion device is controlled to apply different pressures according to the different contents of the cotton fibers. Different pressures will lead to different spacings between the two ends of the extrusion device, but the differential pressure gauge is extended to a fixed position inside the Micronaire value meter. This will cause the differential pressure gauge to be unable to detect the pressure difference at both ends of the cotton fibers. Subsequently, the differential pressure gauge will have deviations when performing Micronaire detection on cotton fibers with different contents. For this reason, we propose a Micronaire value meter for cotton fiber textile production. Utility Model Content
[0004] In view of the shortcomings of existing micronaire value measuring instruments for cotton fiber textile production, the utility model provides a micronaire value measuring instrument for cotton fiber textile production, which has an air collecting chamber that drives a connecting plate to move synchronously, and then when a differential pressure meter detects the cotton fiber, the connecting plate can accurately detect the pressure difference at both ends of cotton fibers with different contents, thereby improving the detection accuracy and solving the problems raised in the above-mentioned background technology.

[0012] Compared with the existing micronaire value tester for cotton fiber textile production, the utility model has the following beneficial effects:
[0013] 1. The micronaire value tester for cotton fiber textile production extends from the tester body to the inside of the sealing sleeve to improve the sealing of the equipment during testing. The micronaire test can be performed on the cotton fiber inside the tester body. After the cotton fiber is tested, the air collecting chamber is controlled to be taken out from the inside of the tester body. When the cotton fiber is blocked inside the tester body, the upper sealing cover can be removed to facilitate the removal of the cotton fiber blocked inside the tester body.
[0014] 2.

The air collecting chamber drives the connecting plate to adjust its position synchronously, and the connecting plate drives the sealing plate to be movably connected to the inside of the measuring instrument body. When the position of the air collecting chamber is adjusted, the connecting plate continuously seals the inside of the slide groove opened in the measuring instrument body to avoid gas leakage when the position of the connecting plate is adjusted, which affects the measurement effect of the micronaire value. The connecting plate is arranged on the inner side of the air collecting chamber, and then the connecting plate accurately detects the gas transmission effect to avoid deviation in the detection between the connecting plate and the air collecting chamber, which leads to the problem of poor detection effect.
