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 guide hole and micropore roundness detection device and method. The guide hole and micropore roundness detection device comprises a spinneret plate detection table, a guide hole roundness detection device, a micropore roundness detection device and a computing terminal; the guide hole roundness detection device is used for shooting first image information of an outer circular hole of a guide hole and an inner circular hole of a micropore and transmitting the first image information to the computing terminal; and the micropore roundness detection device is used for shooting second image information of the outer circular hole of the micropore and transmitting the second image information to the computing terminal. According to the guide hole and micropore roundness detection device and method, the roundness of the guide hole and the micropore is effectively analyzed and detected through a computer algorithm and a position detection standard, so that the problem of roundness defect detection of the guide hole and the micropore is fully solved, and meanwhile, the situation that a single spinneret hole becomes a waste hole due to the fact that the roundness of the guide hole and the micropore is unqualified can be effectively avoided. The efficiency of spinneret plate operation is greatly improved, and the maintenance and detection cost is reduced.
Description
technical field [0001] The invention relates to the field of spinneret detection, in particular to a detection device and method for roundness of guide holes and microholes. Background technique [0002] At present, the spinneret is an important component 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 micropores on the spinneret to extrude fiber bundles with a certain thickness and fine texture. Therefore, the development of spinneret helps to promote the development of new textile fibers. The manufacturing accuracy 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 important...
