Accurate collecting device for carding machine cotton layer thickness

Abstract

A device for accurately measuring the cotton thickness of carding machine is provided, which comprises a cotton feed roller, a cotton feed plate and measuring rods. The cotton feed roller is fixed. The measuring rods are arranged between the cotton feed roller and the cotton feed plate. 2n detection zones are uniformly arranged in the length direction of the whole cotton feed roller, wherein n is an integer larger than 1 and each detection zone is provided with one measuring rod. Each measuring rod collects real-time the fluctuation data of thickness of cotton layer in the zone data. The data collected by each measuring rod are transmitted to a displacement sensor by a scale transmission mechanism. The cotton thickens fluctuation parameter output by the scale transmission mechanism is a geometric mean parameter of cotton thickness data of all detection zones. Since the measured the data are approximate to the real fluctuation condition of cotton thickness, the leveling machine can automatically modulate according to the parameter and thus control the cotton thickness reference scientific and accurate.

Description

Technical field: [0001] The invention relates to a carding machine, in particular to a cotton layer thickness collecting device of the carding machine. Background technique: [0002] Carding machine is the core equipment of textile enterprises. Its main function is to process cotton into uniform sliver, provide high-quality sliver for subsequent drawing and spinning, and minimize the weight of sliver per unit length. uneven. The autoleveler is the control part of the carding machine to produce qualified sliver. The cotton layer thickness data acquisition device is set between the cotton feeding roller and the cotton feeding plate of the carding machine. The data collected by it is sent to the autoleveler through the displacement sensor. The data processing system of the autoleveler performs calculations on the collected cotton layer thickness data, and adjusts the rotation speed of the cotton feeding roller through the cotton feeding motor (frequency conversion motor) to ac...

Problems solved by technology

[0008] With the improvement of textile technology requirements, the quality requirements of spinning mills for sliver are getting higher and higher. In the past, the CV value of sliver weight unevenness was generally controlled at 2 to 3%. Now, with the increase of spinning count, cotton The CV value of uneven bar weight must reach 0.8-1.2%, and the original cotton layer thickness data acquisition system can no longer meet the requirements

Because the existing detection method only has two detection points in the entire length of cotton feeding (about one meter long), the data collected by these two detection points is used as the basis for judging the amount of change in the thickness of the cotton layer throughout the length of cotton feeding. This is obviously imprecise and only roughly controls the thickness of the cotton layer
