Embodiment 1

[0076] A method for measuring package winding density, such as figure 1 As shown, the cheese is composed of the yarn bobbin 3 and the yarn 2 wound on the bobbin. The volume of the yarn in the bobbin is obtained through simulation calculation, and the weight of the yarn in the bobbin is obtained through measurement and calculation. Obtain the winding density of the cheese by volume;

[0077] The steps of simulation calculation are as follows:

[0078] (1) Establish a rectangular coordinate system with the central axis of the yarn bobbin as the coordinate axis, such as image 3 shown;

[0079] (2) Collect the coordinates of multiple points arranged at equal intervals on lines a, b, and c, such as Figure 4 As shown, the yarn is wound into a hollow rotating body, and the rotating body is a cylinder or a circular platform. The lines a, b, and c are respectively corresponding to the intersection lines of the upper end surface, side surface, lower end surface of the rotating body...

Embodiment 2

[0089] Adopt the cheese winding density measuring device of a kind of cheese winding density measuring method as described in embodiment 1, such as figure 2 As shown, it consists of bobbin fixing device 1, distance measuring device I 4, distance measuring device II 7, distance measuring device III 8 and fixing / driving device;

[0090] Yarn bobbin fixing device 1 such as Figure 7 As shown, it is used to fix the bobbin, the bobbin fixing device 1 is partially intercepted frame structure, The shaped frame is composed of a 匚-shaped frame with the opening direction downward and a cylinder vertically connected to the upper surface of the 匚-shaped frame. The interception refers to the interception by two mutually parallel planes, and the two planes are located on both sides of the central axis of the cylinder. Parallel to the central axis of the cylinder, and the distance between the two is smaller than the diameter of the cylinder; the yarn tube is placed on the cylinder, and ...

Embodiment 3

[0108] A method for measuring the winding density of cheese is basically the same as in Example 1, except that the difference is in step (2) and step (3);

[0109] Step (2) is: collect the coordinates of multiple points on the lines a and c, wind the yarn into a hollow rotating body, the rotating body is a cylinder or a circular platform, and the lines a and c correspond to the upper end surface, the lower end surface and the half surface of the rotating body respectively. The intersection line of the section Q, one side of the half section Q coincides with the central axis of the yarn bobbin, and is located on the plane where the Cartesian coordinate system is located at the same time. The default line of intersection is a slanted line or a straight line, and it is not necessary to collect the coordinates of multiple points on line b at this time;

[0110] Step (3) is: fitting the multiple points on the lines a and c to obtain the corresponding fitting curves a*, c* and fitti...

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 ...
