Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of quality inspection equipment, especially relates to a bottle piece quality inspection machine. BACKGROUND
[0002] The bottle piece quality inspection machine belongs to the technical field of plastic recycling and automatic detection, and is mainly used for quality detection and sorting of bottle pieces (PET, HDPE and the like) formed after recycling plastic bottles are broken. With the strengthening of global environmental protection policy and the growth of circular economy demand, the scale of the plastic recycling industry continues to expand, and the purity, color consistency and impurity content of bottle pieces as the core form of regenerated plastic raw materials directly affect the quality of downstream products. Therefore, efficient and accurate bottle piece quality detection has become a key link that the industry urgently needs to break through. In existing automatic detection schemes, visual detection systems based on single optical sensors (such as visible light cameras) are gradually being applied, but their adaptability in complex scenarios is poor. For example, factors such as bottle piece surface reflection, stacking obstruction and environmental light fluctuation can easily lead to unstable imaging quality, affecting the accuracy of algorithm judgment; at the same time, traditional algorithms have low differentiation for black impurities (such as coking particles) mixed in dark bottle pieces or colorless foreign matter (such as PVC fragments) in transparent bottle pieces, and the detection accuracy is difficult to break through 90%. In addition, existing equipment lacks multi-dimensional data fusion capability and cannot simultaneously meet the demand for color, shape, material and other multi-parameter collaborative analysis, resulting in a single sorting strategy and difficulty in meeting the technical problems of high-standard regenerated raw material grading requirements.
