If the differences in the organizational structure of animal skin are ignored and randomly put into the unhairing device, it will inevitably affect the quality stability of the animal skin unhairing skin. Therefore, it is necessary to classify and batch produce animal skin.

[0055] The animal skin classification mechanism comprises a feeding state and a classification state, when in the feeding state, the classification conveying module is connected with the feeding module, and when in the classification state, the classification conveying module is connected with one of the groups of buffer units.

[0056] The animal skin is sent into the feeding module one by one, when the animal skin passes through the detection channel, the detection module detects the animal skin, and the classification unit sends the detected animal skin to the corresponding buffer unit for temporary storage, so as to realize automatic classification of the animal skin.

[0057] In this embodiment, the detection unit analyzes and classifies the animal skin according to at least one parameter such as the area of the animal skin, the mass of the animal skin, the length of the animal hair, and the thickness of the skin plate, and then the classification unit sends the animal skin to the corresponding buffer unit, so as to realize automatic classification of the animal skin, reduce labor intensity, improve the classification accuracy of the animal skin, and avoid misplacement and random placement.
