Feeding Mechanism of a Processing Machine

Abstract

A feeding mechanism of a processing machine comprises a base, a feeding linear actuator, an outer feeding assembly and an inner feeding assembly. The base is disposed at one side of a material feeding path of a processing machine, the feeding linear actuator is disposed in the base, and the arrangement direction of the feeding linear actuator is parallel to the material feeding path of the processing machine. The outer and inner feeding assemblies are orderly assembled to the feeding linear actuator from outside to inside to drive the material respectively, and the driving path of the outer feeding assembly is connected to that of the inner feeding assembly. Such arrangements not only can simplify the structure and increase the working efficiency, but also can reduce the occupied space.
