Technical Field
The utility model belongs to the technical field of automated inspection, a solution cavity automatic identification of filter rod detects, especially a filter rod solution cavity detection device is related to.
Background
In the process of forming the cigarette filter stick, glyceride is required to be sprayed on fiber tows in order to improve the forming quality, abnormal liquid drops of the glyceride are sometimes formed due to backflow in the spraying process of the glyceride, and if the glyceride drops into the tows in the production process, a 'karst cave' is formed in the process of solidifying the filter stick. The karst cave can not appear immediately when the production of the filter stick is finished, and can only appear after 12-24 hours of solidification. Therefore, the occurrence of the filter rod cave has certain concealment. In addition, the filter stick cave is formed by the backflow of glyceride liquid drops, and has certain randomness. The filter stick containing the karst cave belongs to products with quality defects and can not flow into the production link of cigarettes.
At present, automatic detection equipment for the occurrence of filter rod karst caves does not exist in the market, and the detection of the filter rod karst caves completely depends on manual work, consumes time and labor and is low in efficiency.
