Cheese winding density measuring method and device

Abstract

The invention relates to a cheese winding density measuring method. Cheese is composed of a bobbin and yarn wound on the bobbin, the volume of the yarn in the cheese is obtained through analog calculation, meanwhile, after the weight of the yarn in the cheese is obtained through measurement and calculation, the weight is divided by the volume to obtain the winding density of the cheese. The invention further provides a cheese winding density measuring device. The cheese winding density measuring device is composed of a bobbin fixing device, two or three distance measuring devices and a fixing / driving device. The bobbin fixing device is used for fixing a bobbin; the distance measuring device is connected with the fixing / driving device and used for collecting coordinates of multiple points on the yarn; and the fixing / driving device is used for fixing and driving the distance measuring devices. The method and the device can be used for safely, simply, conveniently and accurately measuringthe winding density of the cheese, and have great popularization value.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a method and a device for measuring the winding density of cheese. Background technique [0002] When the package yarn is dyed in the dye solution of the same concentration, different dyeing effects will be produced due to different winding densities, resulting in quality differences. Therefore, according to the winding density of the package yarn, put it into the dye solution of the corresponding concentration Dyeing is very critical to the dyeing quality of cheese. [0003] At present, the common measurement methods of package yarn winding density are as follows: [0004] (1) Use a Shore hardness tester to estimate at the production site. This method is quick and easy, but the accuracy is slightly poor, and the proficiency of the test personnel is high; [0005] (2) Calculation by calculation formula. Specifically, the package yarn is idealized so that the surface of the yarn ...

AI Technical Summary

Problems solved by technology

[0004] (1) Use a Shore hardness tester to estimate at the production site. This method is fast and simple, but the accuracy is slightly poor, and the proficiency of the test personnel is required;

[0005] (2) Calculation by calculation formula. Specifically, the package yarn is idealized so that the surface of the yarn is flat and has no unevenness, and after measuring all the size data of the package yarn, it is substituted into the formula to calculate the winding density. The process is cumbersome and the error is large

[0006] In order to measure more easily, some researchers use machine vision technology to measure and calculate the winding density of cheese. Although this method is simple, machine vision will regard the uneven surface of cheese as a flat plane due to its own characteristics. There will also be a situation where the convex part will block the concave part, so the accuracy is poor. For example, the prior art discloses a method of testing the winding density using Y-ray computed tomography (YRCT), which is measured by the quality of the cheese Indirect estimation of the density value has poor accuracy. In addition, it will cause irreversible damage to the human body, and there are problems with safety.
