Autoleveling system with cotton silver weighing control and weight control method thereof

Abstract

The invention relates to an autoleveling system with cotton sliver weight control and a weight control method thereof. The autoleveling system comprises a cotton-feeding roller mechanism, a coiler, a cotton sliver bucket, an autoleveling device, a cotton layer thickness detection sensor and / or a cotton sliver thickness detection sensor, and a weight sensor for weighting a cotton sliver in the cotton sliver bucket, wherein the output end of the weight sensor is connected with the autoleveling device for controlling the output speed of the cotton-feeding roller mechanism; the weight sensor comprises a strain foil and a weight amplifier, and the strain foil is a bridge resistor circuit. The autoleveling system detects the weight of the cotton sliver after a certain length of cotton sliver is continuously produced, and the autoleveling device compares a detected weight with a standard weight stored in a program and controls the output speed of the cotton-feeding roller mechanism according to a comparison result. The invention realizes the online weight detection of an overlength section of cotton sliver, can effectively correct the weight deviation of the overlength section of cotton sliver in time, lightens the labor intensity of an operator and improves the detection precision.

Description

technical field [0001] The invention relates to a sliver quantitative control mechanism of a blowing-carding combined carding machine, in particular to an autoleveling system with sliver weighing control and its weight control method which can detect the weight of super-long segment sliver on-line and its weight control method. Textile machinery field. Background technique [0002] In the prior art, in order to control the unevenness of the sliver in the process of processing the cotton fiber by the carding machine, there are basically three kinds of control forms used in the autoleveler control system, open-loop control, closed-loop control and mixed-loop control . Among them, the open-loop control is to use the displacement sensor at the cotton feeding roller to detect the thickness of the fed cotton layer and control the unevenness of the short segment of the sliver; the closed-loop control is to use pressure detection at the cotton outlet bell mouth or use concave-conve...

Problems solved by technology

In the production process, it is not only one machine that is biased, but most of the machines are light or heavy at the same time. In the past, the production plant relied on manual sampling and weighing of each machine in the laboratory to manually adjust the weight of each machine. The given value of machine autolevelling corrects the weight deviation of cotton sliver, but this belongs to off-line control and hysteresis adjustment. If the laboratory does not find and correct it in time, the weight deviation will be more severe, resulting in a lot of waste sliver, and the subsequent drawing The process will change teeth frequently
