Abstract

The invention belongs to the technical field of stationery commodities, and relates to a semi-automatic pencil-sharpening machine. The semi-automatic pencil-sharpening machine comprises a rack, a rotary motor-speed reducer combination, a rotary disc, a cutting motor, a cutting cutter disc and a plurality of pencil fixing assemblies. An inner gear ring is horizontally arranged on the rack. The rotary disc is in a disc shape, and a plurality of mounting holes are formed in the edge of the rotary disc. An output shaft of the rotary motor-speed reducer combination is fixedly connected with a hub. Each pencil fixing assembly comprises a small gear and a plurality of snap springs, and the pencil fixing assemblies are mounted in the mounting holes. The small gears are engaged with the inner gear ring, and a hole is formed in the middle of each small gear. Each snap spring is in a hollow barrel shape and is provided with a plurality of sections and fixedly connected in the hole of the corresponding small gear. The cutting cutter disc is conical, cutting edges are arranged on the periphery of the cutting cutter disc, and the hub is fixedly connected with an output shaft of the cutting motor. The semi-automatic pencil-sharpening machine achieves semi-automatic treatment and is high in treatment efficiency; and students do not need to sharpen pencils manually and can have a rest outdoors at break, asthenopia is relieved, nearsightedness is effectively avoided, and a large amount of time of the students is saved.

Description

technical field [0001] The invention belongs to the technical field of stationery, and relates to a semi-automatic pencil sharpening device, in particular to a semi-automatic pencil sharpener. Background technique [0002] In the early days, students used a pencil sharpener to sharpen pencils by hand. This work was often done during breaks, holding a pencil in one hand and a pencil sharpener in the other. While sharpening, slowly rotate the pencil so that this end becomes approximately conical and exposes the lead. , and then scrape the lead into an approximate conical shape. [0003] This method has the lowest work efficiency and takes the longest time. It is also easy to break the lead when scraping the lead. If it is broken, it needs to be re-cut, which is a waste of time. In addition, it is easy to get dirty hands, so that the pencil dust sticks to the hands. Some elementary school students have a bad habit of sucking their fingers, and they will suck the pencil dust in...
