Automatic cutter for printer

Abstract

The invention provides an automatic cutter for a printer, which comprises a horizontally placed fixed cutter and a circular cutter in sliding connection with the fixed cutter, the fixed cutter inclines downwards and forms an angle less than 90 degrees with the vertical direction, and the front end of the circular cutter along the paper cutting direction is attached to the cutting edge of the fixed cutter. An included angle is formed between the rear part of the cutter blade and the cutting edge of the fixed cutter and is an acute angle; according to the automatic cutter, a certain included angle is formed between the circular cutter body and the fixed cutter body, the circular cutter body and the fixed cutter body are meshed more sufficiently, the paper cutting quality can be improved, parts are reduced, assembling is easy and convenient, the requirements for part machining and manufacturing precision are lower, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to an automatic cutter for printers. Background technique [0002] The printer is a device that prints the calculation results or intermediate results of the computer on paper in accordance with the specified format in numbers, letters, symbols and graphics that can be recognized by humans. The existing A4 thermal printer paper does not have an automatic cutter. After the printer prints out the paper, it needs to be torn off manually. Manual tearing is not only inefficient, but also the torn paper is prone to problems such as unevenness. Although some structures can realize automatic paper cutting at present, there are the following problems: [0003] 1. At present, the meshing between the circular cutter and the fixed knife is insufficient, resulting in poor paper cutting. Otherwise, the accuracy of the parts needs to be improved to ensure the meshing between the circular cutter ...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, the meshing between the circular cutter and the fixed knife is insufficient, resulting in poor paper cutting. Otherwise, the accuracy of the parts needs to be improved to ensure the meshing between the circular cutter and the fixed knife, but the processing cost increases and the consistency is difficult to guarantee;

[0004] 2. The cutter reversing mechanism is complicated, and there are many parts, which increases the cost of parts and assembly, and the structure is complicated and the reliability is poor.
