The invention discloses a feeding mechanism achieving continuous leather material guide and preventing a material from being stuck. The feeding mechanism comprises a feeding guide mechanism and pressplate guide mechanisms. The press plate guide mechanisms are used for pressing the edges of the leather material to sharp teeth of conveying chains with the sharp teeth, and therefore the leather material can be dragged by the conveying chains with the sharp teeth to move after the sharp teeth of the conveying chains with the sharp teeth pierce the edges of the leather material. Each press plate guide mechanism comprises a lower guide plate and an upper guide plate. The lower guide plates and the upper guide plates are installed on a lifting driving mechanism, and therefore the lower guide plates and the upper guide plates can be driven by the lifting driving mechanism to ascend and descend, and the piercing depths of the sharp teeth of the conveying chains with the sharp teeth are adjusted. According to the feeding mechanism, the upper guide plates and the lower guide plates in the press plate guide mechanisms ascend and descend to adjust the depths of the sharp teeth, piercing the leather material, of the conveying chains with the sharp teeth, and therefore the pull force of the conveying chains with the sharp teeth and on the two sides to the leather material is adjusted, and the frequency of the phenomenon that the leather material swings leftwards and rightwards is reduced; and the press plate guide mechanisms are combined with a series of limiting devices on the feeding guide mechanism, the phenomenon that the leather material swings leftwards and rightwards and fluctuates is avoided, and therefore the material is prevented from being stuck.
