[0027] This handwriting erasing machine is roughly the same as the handwriting erasing machine of the first embodiment, and its main difference is that: the extensions of the two opposite "door" shaped sides are all provided with a plurality of first positioning holes, and are respectively arranged on The first positioning holes on the extension of the two opposite "door" shaped sides correspond one-to-one, and the distance between the positioning holes is 1 / 2 of the outer diameter of the grinding head. There is a first protrusion at the middle of the bottom of the two ends of the hand; a plurality of second positioning holes are provided on the inner extension of the two opposite "door"-shaped sides, and are respectively arranged on two opposite sides. The second positioning holes on the inner extension of the "door"-shaped side correspond one-to-one, and the distance between the positioning holes is 1 / 2 of the outer diameter of the gear. Each of the middle positions of the e...

Abstract

The invention provides a writing eliminating machine comprising a paper placement plate and a paper pressing plate. The paper placement plate is used for placing paper to be treated; the paper pressing plate is used for pressing and holding the paper to be treated, and comprises a grinding unit positioned between the paper placement plate and the paper pressing plate; and the grinding unit moves along the top of the paper pressing plate under the action of an external driving source and is used for carrying out grinding treatment of the paper which is to be treated and is placed on the pressing plate. The writing eliminating machine removes writing clearly without obvious marks, has simple structure and flexible and convenient use and carrying, is widely used, and can reduce the office cost.

Description

【Technical field】 [0001] The invention relates to a handwriting erasing machine. 【Background technique】 [0002] In daily life, people often need to correct or eliminate the wrong handwriting on the paper and the dirty traces caused by other reasons. At present, the commonly used methods mainly include eraser erasing, blade scraping, correction fluid coverage, and adhesive tape removal. When erasing with an eraser or scraping with a blade to remove writing and other traces on the paper, the paper is often damaged due to uneven force. In addition, the removal speed is also slow, time-consuming and laborious. The correction fluid is a suspension, and it becomes a powder after volatilization, which is easy to fall off and leaves obvious marks. In addition, its smell is unpleasant and affects health. When using adhesive tape to remove handwriting or other traces on paper, it is necessary to cut the adhesive tape with scissors, which is inconvenient to operate. In addition, the...
