Automatic pen feeding device

Abstract

The invention relates to an automatic pen feeding device. The device comprises a base, wherein a fluted disc is inserted into the front side of the base, a plurality of racks are evenly distributed on the front end face of the fluted disc in a circumferential mode, two parallel rotary shafts are arranged above the fluted disc, the two ends of each rotary shaft are fixed to the base through a first support and a second support respectively, a pen rolling leather ring is fixed to each rotary shaft, helical gears are arranged on the rotary shafts in a sleeving mode and located at the right side of the upper pen rolling leather ring and at the left side of the lower pen rolling leather ring respectively, and the helical gears are meshed with the racks arranged on the fluted disc. The structure is novel, the product structure is optimized, the racks are evenly distributed on the fluted disc in the circumferential mode, and the helical gears are meshed with the racks; due to the fact that the racks are evenly distributed, continuity is realized, gear jumping and locking are avoided, pen feeding and pen discharging are both smooth, noise is low, and service life is long.

Description

technical field [0001] The invention relates to an automatic pen feeding device. Background technique [0002] There are many types of pencil sharpeners on the market at present, and their performances are not the same. The quality of the pen feeder in the structure of the pencil sharpener directly affects the performance of the pencil sharpener, but the pen feeder on the market generally consists of a base, a toothed plate , a gear and a pen roller apron, and the gear is in contact with the toothed disc. This kind of pen feeding device has the following problems in specific use: it will produce abnormal noises when sharpening the pen, and the hand feel is not smooth, and there is obvious cracking after sharpening. The grinding noise of the gears is annoying, and it is also difficult to return the pen. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an automatic pen feeding device. [0004] The automatic w...
