Drying agent feeding machine

The utility model discloses a drying agent feeding machine which comprises a feeding mechanism, a material cutting structure, a material clamping mechanism and a falling channel which are sequentially arranged from top to bottom, and an upper correlation optical fiber and a lower correlation optical fiber are arranged up and down and are both arranged right opposite to the falling channel. The drying agent feeding machine further comprises a lifting adjusting mechanism used for adjusting the distance between the upper correlation optical fiber and the lower correlation optical fiber. Compared with the prior art, the drying agent feeding machine can be used for quickly and accurately detecting the length of the cut drying agent. The drying agent feeding machine has the advantages of being simple in structure and low in cost. 本实用新型公开了一种干燥剂投放机，包括由上至下依次设置的送料机构、切料结构、夹料机构和下落通道，所述上对射光纤和下对射光纤上下设置且二者均正对所述下落通道设置，所述干燥剂投放机还包括用于调节所述上对射光纤和下对射光纤之间的距离的升降调节机构。与现有技术相比，采用本实用新型的干燥剂投放机可对切断后的干燥剂的长度进行快速精确地检测。且本实用新型的干燥剂投放机具有结构简单，成本低
