Printer automatic paper cutter structure

Abstract

The invention discloses an automatic paper cutter structure of a printer, which is arranged at the paper outlet of the printer, and comprises an upper upper cutting blade and a lower lower cutting blade; The cutting blade is formed by butting two pieces. Because the paper cutter of the present invention decomposes the lower cutting blade from one piece to the left and right two pieces, when the printer is cutting paper, when the upper and lower blades are combined and cut, the butt joint between the left lower cutting blade and the right lower cutting blade can be released. Due to the stress generated during the fit, the resistance of paper cutting will be reduced, and the left and right lower cutting blades will not affect each other, so that the paper cutting action is smooth, and the life of each cutting blade is greatly improved.

Description

technical field [0001] The invention relates to printer components, in particular to a printer automatic paper cutter structure. Background technique [0002] At present, micro-printers are used in a wide range of places, and the accuracy of their functions is the guarantee for increasing their efficiency. [0003] The traditional automatic paper cutter structure for micro printers, such as figure 1 , 2 As shown, the automatic paper cutter structure is located at the paper outlet of the printer, and it is composed of an upper cutting blade 1' and a lower cutting blade 2', and the two cutting blades are relatively active; wherein the upper cutting blade 1' The cutting edge 11' forms a "V"-shaped notch from its center to both ends, and the cutting edge 21' of the lower cutting blade 2' is in a straight line. The action of paper cutting is to rely on the upper cutting blade 1' and the lower cutting blade 2' to achieve the effect of cutting the paper, while the function of fu...

AI Technical Summary

Problems solved by technology

[0005] 1. The paper cannot be cut when the paper is fully cut, which affects the performance;

[0006] 2. The cutting life is limited, and the paper cutting is not smooth enough

[0007] The reason for the above two problems is that during the paper cutting process, the stress of the upper cutting blade 1' and the lower cutting blade 2' when they are cut is all squeezed to the middle of each cutting blade, causing great resistance, especially The lower cutting blade 2' whose cutting edge 21' is in a straight line will have greater resistance; if there is a slight deviation in the left and right elastic control of each cutting blade, it will affect each other, so that the paper cannot be cut
