Problems solved by technology
[0005] For guide holes and micro-holes, if the roundness of the guide holes and micro-holes is unqualified, this processing defect can easily affect the state of the melt in the hole, which will have a significant impact on the molding quality of textile fibers. And the unqualified roundness of the microholes will also make a single spinneret hole in the spinneret become a waste hole, and even directly affect the service life of the entire spinneret
If the roundness of the guide hole and the microhole is not detected in time, it will cause a very serious loss and waste of time, material and equipment costs
However, in the prior art, there is no technical solution for special detection of the roundness of the guide hole and the microhole. In view of the problems existing in the prior art, it is useful to provide a detection device and method for the roundness of the guide hole and the microhole. important meaning

Abstract
The invention discloses a detection device and method for roundness of guide holes and microholes, comprising a spinneret detection platform, a detection device for roundness of guide holes, a detection device for roundness of microholes and a computing terminal; the roundness detection of the guide holes The device is used to photograph the first image information of the outer circular hole of the guide hole and the inner circular hole of the microhole and transmit the first image information to the computing terminal; the microhole circularity detection device is used to photograph The second image information of the outer circular hole of the microhole and the second image information are transmitted to the computing terminal. Using the detection equipment and method for the roundness of guide holes and microholes of the present invention, the roundness of guide holes and microholes can be effectively analyzed and detected through computer algorithms and position detection standards, which fully solves the problems of guide holes and microholes. The problem of roundness defect detection can effectively avoid the single spinneret hole becoming a waste hole due to the unqualified roundness of the guide hole and the microhole. The efficiency of the spinneret operation is greatly improved, and the maintenance and inspection costs are reduced.
Description
technical field [0001] The invention relates to the field of spinneret detection, in particular to a detection device and method for the roundness of guide holes and micro holes. Background technique [0002] At present, spinnerets are important components in the textile industry, especially in the chemical fiber industry. As an indispensable precision part of the spinning machine in the chemical fiber industry, its function is to extrude the precisely metered spinning melt or solution through the micro-holes on the spinneret to extrude fiber bundles with a certain thickness and fine texture. Therefore, the development of spinnerets helps to promote the development of new textile fibers. The manufacturing precision of the spinneret determines the quality of the fiber forming, and the shape of the micropores of the spinneret determines the cross-sectional shape of the fiber, which in turn affects the comfort of the fabric. Therefore, the quality of the spinneret is an impor...
