Knife grinding device for plastic packaging bag shearing knife

Abstract

The invention discloses a knife grinding device for a plastic packaging bag shearing knife. The knife grinding device comprises a bottom plate, a grinding assembly, a moving assembly and a clamping assembly, wherein the grinding assembly, the moving assembly and the clamping assembly are arranged on the bottom plate, the grinding assembly comprises a mounting table and a motor arranged at the topof the mounting table, and a knife grinding stone is arranged on an output shaft of the motor. The clamping assembly is fixed to the moving assembly. According to the knife grinding device for the plastic packaging bag shearing knife, a cutting edge is ground in a semi-automatic mode, the knife grinding efficiency is improved, the labor intensity of workers is reduced, a blade fixing plate with the adjustable inclination angle is arranged, the grinding inclination angle of the knife grinding stone to the cutting edge can be adjusted according to actual needs, and the applicability is good; anadjustable blade locking assembly is arranged, and rectangular blades of different size can be adapted and locked and ground; and the knife grinding device is simple in structure, low in requirement for the installation environment, not prone to breaking down and simple in later maintenance and repair.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for shearing knives of plastic packaging bags, in particular to a sharpening device for shearing knives of plastic packaging bags. Background technique [0002] In the production process of plastic packaging bags, the last process is to cut the continuous strips of plastic bags into individual plastic bags. In this process, a rectangular blade is used to cut the plastic bags. After working for a long time, the blade It will inevitably be worn, so it needs to be ground regularly to maintain the sharpness and flatness of the blade. At present, the blade is usually trimmed manually. Manual sharpening has the defects of high labor intensity, slow speed and low efficiency. Therefore, a The knife sharpening device assists the worker to trim the blade efficiently. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defe...
