Fixed-mass cotton fiber sample producer

Abstract

The invention discloses a fixed-mass cotton fiber sample producer comprising a fixed-mass cotton fiber sample accurate extraction mechanism and a cotton fiber sample storage mechanism; the lower portion of a storage funnel is connected with a cotton fiber sleeve, the lower end of the cotton fiber sleeve is fixedly connected with an air suction port formed in the rear portion of a fixed bottom plate, and the lower portion of the air suction port is connected with an air pump; the rear part of a rear seat plate is provided with a straight rod pressure sensor, the straight rod pressure sensor penetrates through a lantern ring to be connected with a pressure transmission rod, an auxiliary sleeve is arranged outside the pressure transmission rod, a cutter mechanism is arranged between the cotton fiber sleeve and the auxiliary sleeve, and the cutter mechanism comprises an electrically conductive slip ring and an arc-shaped cutter. The fixed-mass cotton fiber sample producer is used for obtaining a detection sample with the mass of 10 grams and with the error within the range of + / -5%, meets the HVI micronaire value detection requirement, the domestic cotton fiber detection efficiency is greatly improved, the manpower difficulty in cotton fiber detection is improved, and the cotton fiber detection benefits are improved.

Description

technical field [0001] The invention relates to the technical field of cotton fiber detection, in particular to a constant-quality cotton fiber sample generator. Background technique [0002] At present, in 2005, Uster has developed a high-end instrument HVI1000 cotton fiber inspection platform for all-round inspection of cotton fiber, that is, a large-capacity fiber tester, which adopts advanced modular design and has a total length / strength , color / impurity, micronaire value / maturity and nep meter, etc. 4 sets of modules, which can realize the integrated inspection of cotton fiber with manual assistance. The HVI inspection machine has a fast inspection speed and can test a cotton sample within 40 seconds. The inspection is accurate and the consistency of the inspection data is high. [0003] Compared with foreign countries, the proportion of family units in domestic cotton fiber is relatively high, the climatic conditions of cotton fiber production areas are quite differe...

Problems solved by technology

When the HVI1000 cotton fiber inspection platform inspects cotton fiber micronaire, the inspector needs to manually pick a part of the test sample from the test sample and place it in the cotton fiber micronaire inspection hole of the HVI1000 cotton fiber inspection platform. Cloning inspection requires a 10-gram inspection sample with a small error, and manual weighing operation is required. Due to the large manual error, it usually requires manual weighing for many times. The above situation has further caused the following dilemma in the domestic cotton fiber inspection industry. , including 1) high work intensity, long operation time, low work efficiency, 2) detection errors caused by operator fatigue, 3) differences in operating techniques and proficiency, resulting in differences in test results, 4) fiber dust causing occupational diseases and 5) peak season Insufficient personnel and idle personnel in off-season restrict the efficiency and effectiveness of cotton fiber testing
