Abstract

This invention discloses an automatic check valve sprue trimming device and method, belonging to the field of sprue trimming technology. It includes a feeding conveyor, a discharging mechanism, a material handling and transferring mechanism, and a shearing mechanism mounted on a machine base. The feeding conveyor is fixedly mounted on the machine base. The discharging mechanism includes a linear motion module, a material transfer plate, and a plate positioning assembly. The linear motion module is fixedly mounted on the machine base, and multiple moving plates are fixedly mounted on the moving end of the linear motion module. A positioning frustum is fixedly mounted on the material transfer plate. Plate positioning assemblies for positioning the material transfer plate are symmetrically mounted on the machine base. The material handling and transferring mechanism includes a material transfer assembly, an adjustable mounting structure, and a pre-positioning material picking assembly. A shearing mechanism for trimming the plastic parts after repositioning the check valve accessories is mounted on the machine base, the material transfer assembly, and the adjustable mounting structure. This method achieves precise trimming of the sprues of multiple plastic parts at once, ensuring trimming efficiency.
