Abstract

The invention discloses an acetate fiber tow splicing section detection method and device, and the method comprises the steps: enabling visible light to penetrate through a tow, enabling the visible light to be reflected by a reflector, enabling the visible light to penetrate through the tow again, and enabling the visible light to enter an illuminance array sensor; obtaining an illuminance data column according to the reflected light received by the illuminance array sensor; calculating illuminance average data according to the illuminance data column, and calculating the width of the tow; dividing the illuminance data column into a background data column and a target data column, and calculating average illuminance data of the target data column; and judging the current tow state according to the tow width and the average illuminance data of the target data column. According to the acetate fiber tow splicing section detection method and device, based on the illuminance detection technology, the corresponding absorption wave band of the tow is adopted as a light source to irradiate the tow, receive the emitted light of the tow, detect the reflected illuminance and carry out data processing so as to judge which working condition the tow is in currently, and the accuracy and effectiveness of equipment removal are improved; and material loss is reduced.

Description

technical field [0001] The invention relates to the technical field of tobacco detection, in particular to a method and a device for detecting a spliced ​​segment of an acetate fiber tow. Background technique [0002] In the process of filter rod production, during the splicing process of the previous tow package and the next tow package, it is necessary to perform high-temperature welding on the spliced ​​section, so as to facilitate the non-stop production of the equipment. Due to the high temperature welding, the tow of the spliced ​​section can not be air-opened and loosened due to the formation of carbonized weld scars, so it needs to be directionally removed. At present, the common operation methods of splicing segments include: manual holding method, fixed-point marker elimination method and tow width detection and elimination method. [0003] The manual lifting method requires the operator to observe whether the spliced ​​section enters the filter rod channel from t...
