Pencil production grinding device

Abstract

The invention discloses a pencil production grinding device. The pencil production grinding device comprises a conveyor belt, and is characterized in that a pressing belt is arranged above the conveyor belt, a pressure regulating unit is arranged on the inner side the pressure belt, and the pressure regulating unit comprises a plurality of pressure regulating assemblies arranged in parallel; eachpressure regulating assembly comprises a fixing bracket, a rotating shaft and a columnar cam; the fixing brackets are opened downwardly to for opening portions; the two ends of the rotating shafts aredisposed on the opposite side walls of the opening portions, and the columnar cams are disposed on the rotating shafts; the distances between the axes of the columnar cams of the pressure regulatingassemblies and the corresponding axes of the rotating shafts are not equal; a grinding roller set is rotatably arranged on the outer side of the conveyor belt, the grinding roller set includes a center roller and a plurality of grinding rings arranged above the outer wall of the center roller in parallel in a sleeving mode, and the grinding rings have different surface roughness. The pencil production grinding device realizes automatic grinding of a pencil tip in the pencil production process, improves the grinding quality, and improves the production efficiency at the same time.

Description

technical field [0001] The invention relates to the field of pencil production, in particular to a pencil production grinding device. Background technique [0002] The front ends of pencils are now sharpened when bought, which is convenient for students to use directly for the first time, avoiding the temporary lack of spare tools to sharpen. At present, the equipment for producing pencils is mainly to hold the pencil in one position, and then ream it with a reamer. The efficiency of a single operation is low, and it is not suitable for the production efficiency requirements of mass production of pencils, and does not meet the automation of modern production. Require. [0003] For this reason, the Chinese utility model with the existing publication number CN205416907U discloses "a kind of pencil sharpening device for pencils", which includes a frame and an accommodating hopper arranged on the frame for holding pencils. The bottom of the accommodating hopper gradually shrin...
