The invention relates to cutting equipment, in particular to cutting equipment of fiber preparation raw materials for chemical engineering. According to the technical aim, the cutting equipment of the fiber preparation raw materials for chemical engineering is safe in use, high in work efficiency and good in use effect. In order to achieve the technical aim, the cutting equipment of the fiber preparation raw materials for chemical engineering comprises a second belt wheel, a guide rail, a third bearing pedestal, a third rotary shaft, a fourth bevel gear, a containing plate, a first support, a first rotary shaft, a first bearing pedestal, a first bevel gear and the like. A second rotary shaft is arranged on a second bearing pedestal, the second belt wheel is connected to the second rotary shaft, and the first bearing pedestal and a motor are sequentially arranged on the left side of the first support from bottom to top. The cutting equipment achieves the effects of being safe in use, high in work efficiency and good in use effect and reducing labor force, and the cutting equipment can cut the chemical raw materials conveniently and fast and is uniform in cutting and good in use effect.
