Abstract
The invention discloses an on-line detection and control method for hot-melt defects based on visual analysis, and relates to the technical field of on-line detection of hot-melt defects. The present invention includes the following processes: A00: photographing a hot-melt image of the hot-melt slurry inside the hot-melt machine through a high-definition camera; A01: detecting the current hot-melt temperature of the hot-melt slurry inside the hot-melting machine by a temperature sensor; A02: taking a picture of the hot-melt liquid Perform analysis to obtain the identified bubble density at the current hot-melt temperature; A03: When judging whether the identified bubble density is greater than the bubble density threshold; it shows that there is no hot-melt defect globally. By judging and identifying that the bubble density is greater than the bubble density threshold, the present invention shows that there is no hot melt defect globally, and improves the monitoring effect of the hot solution of the melt-blown cloth during the hot melting process; in addition, when judging whether the uneven ratio is greater than the uneven threshold, the There is no hot melt defect globally or locally; it ensures efficient monitoring of the uniformity of the hot solution of the melt-blown cloth during the hot-melting process, which is convenient and practical.
Description
technical field [0001] The invention belongs to the technical field of on-line detection of hot-melt defects, in particular to an online detection and control method based on visual analysis of hot-melt defects. Background technique [0002] Meltblown cloth is the core material of masks. Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. There are many voids, fluffy structure, good wrinkle resistance, and the ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorbing materials and wiping cloths and other fields. [0003] The melt-blown cloth filter material is randomly distributed and bonded together by polypropyl...
