Technical Field
[0001] The present invention relates to the technical field of blue skin detection equipment, and in particular to a blue skin detection and grading device. Background Art
[0002] The textile, footwear and leather industries are traditional pillar industries of my country's national economy and important livelihood industries, and they play an important role in my country's industrial economy and social development. In recent years, the annual output of my country's large-scale leather enterprises has accounted for 25% of the world's total leather output, ranking first in the world. my country has become a veritable world leather-making power and is actively moving towards the ranks of the world's leather-making powers. As a recognized leather production power, it is also a leather product export earning power, and also a leather product consumer power.
[0003] Leather products have become one of the common products in people's lives. With the increasing demand today, people have high requirements for the quality of leather products. In the leather production and manufacturing process, blue leather is a semi-finished product of leather. After the leather raw materials are made into blue leather, they can be stored and transported for a long time. Because injuries are common quality problems of leather products, mainly due to various reasons in the process of animal breeding and processing, the leather surface will be left with injuries, resulting in damage to the grain and greatly reducing the utilization rate. Therefore, after the blue leather is made, it needs to be tested and graded to determine which leather finished product the blue leather to be processed is suitable for making later, and different processing techniques are formulated according to the final product form. Therefore, different grades determine what kind of products the blue leather can be made into, and also determine the price of the product. Therefore, the detection and grading of blue leather is particularly important. The existing technology is to detect and grade blue leather by image acquisition and computer analysis. However, before the detection, the blue leather is transported and placed by a clamping device such as a machine, which often causes the blue leather edge to overlap or wrinkles to appear during placement, which affects the accuracy of blue leather detection and grading.
