The invention discloses improved environment-friendly panel machining treatment equipment. The improved environment-friendly panel machining treatment equipment comprises a machining body arranged ona supporting arm in an up-down sliding manner, and a panel cutting frame arranged on the left side end face of the machining body. The supporting arm is internally provided with a dovetail groove witha leftward opening. A linkage column is arranged in the dovetail groove in a sliding manner. The left end face of the linkage column is fixedly connected with the machining body. The linkage column is internally connected with a spiral rod in a spiral fit manner. The lower position of the spiral rod is connected with the bottom end wall of the dovetail groove in a rotation fit manner. The upper position of the spiral rod is connected with a main driving machine in a matched manner. The improved environment-friendly panel machining treatment equipment is simple in structure and convenient to operate, automatic control over the lifting panel cutting work of a cutting cutter is conveniently achieved, and the panel cutting work safety and work efficiency are improved.
