Abstract
The invention discloses a kind of automatic paper-cutting knife structure of printer, is the exit slot place being located at printer, and it comprises the upper cut-off knife sheet of top and the lower cut-off knife sheet of below; Wherein this lower cut-off knife sheet to be docked with bottom right cut-off knife sheet two panels by lower-left cut-off knife sheet to form.Because lower cut-off knife sheet is decomposed into two lamellar bodies in left and right by a slice by hand papercutter of the present invention, then printer is when cut paper action, upper bottom knife is when involutory cut-out, the stress that lower-left cut-off knife sheet and bottom right cut-off knife sheet joint produce when can discharge involutory, the resistance of cut paper can reduce, and the lower cut-off knife sheet of left and right can not influence each other, and makes cut paper action very smooth and easy, and the life-span of each cut-off knife sheet is made to be greatly enhanced.
Description
Technical field
The present invention relates to printer unit, refer to a kind of automatic paper-cutting knife structure of printer especially.
Background technology
At present, widely, the accuracy of its various functions is the guarantee increasing its service efficiency to mini-printer application places.
Traditional for mini-printer automatic scudding knife structure, as shown in Figure 1, 2, this automatic scudding knife structure is the exit slot place being located at printer, and it is made up of with lower cut-off knife sheet 2 ' upper cut-off knife sheet 1 ', and two cut-off knife sheets are relative active state; The Shi Ziqi center, cutting edge edge 11 ' of wherein going up cut-off knife sheet 1 ' forms " V " type breach to two ends, and the cutting edge edge 21 ' of lower cut-off knife sheet 2 ' is in straight line.The action of cut paper relies on upper cut-off knife sheet 1 ' mutually to suit with lower cut-off knife sheet 2 ' effect reaching and cut off paper, and be realized by upper cut-off knife sheet 1 ' and the penetraction depth of lower cut-off knife sheet 2 ' for the function of full cut paper and half cut paper, full cut paper herein refers to and is all cut off by paper; And half cut paper refers to and will leave a little disconnected pattern not having to be cut off in the middle of paper.
But but there are the following problems for this traditional automatic scudding knife structure:
1, paper cannot be cut off during full cut paper, affect serviceability;
2, cut restricted lifetime, cut paper is smooth and easy not.
Studying carefully its reason producing above-mentioned two problems is due in cut paper process, upper cut-off knife sheet 1 ' all extrudes with the stress of lower cut-off knife sheet 2 ' when suiting in the middle of each cut-off knife sheet, cause resistance very large, the particularly lower cut-off knife sheet 2 ' of cutting edge edge 21 ' in straight line, its resistance formed can be larger; If each cut-off knife sheet left and right elastic force controls slightly deviation, just can influence each other, to such an extent as to paper cannot be cut off.
Summary of the invention
The object of this invention is to provide a kind of automatic paper-cutting knife structure of printer, it can ensure smoothness and the stability of cut paper, ensures the service life of cut-off knife sheet.
For achieving the above object, solution of the present invention is:
A kind of automatic paper-cutting knife structure of printer, be the exit slot place being located at printer, it comprises cut-off knife sheet and lower cut-off knife sheet; Wherein: this lower cut-off knife sheet to be docked with bottom right cut-off knife sheet two panels by lower-left cut-off knife sheet to form, and joint is supported by support nail and connects.
The Shi Ziqi center, cutting edge edge of described upper cut-off knife sheet forms " V " type breach to two ends, in the middle of this breach, form a short slot.
After adopting such scheme, lower cut-off knife sheet is decomposed into two lamellar bodies in left and right by a slice by hand papercutter of the present invention.When lower-left cut-off knife sheet and bottom right cut-off knife sheet and upper cut-off knife sheet do cut paper action, the resistance of cut paper can reduce, and the lower cut-off knife sheet of left and right can not influence each other, and cut paper action is very smooth and easy, also makes the life-span of each cut-off knife sheet be greatly enhanced.

Detailed description of the invention
As shown in Fig. 3 to Fig. 9, present invention is disclosed a kind of automatic paper-cutting knife structure of printer, it is arranged on the exit slot place that printer prints module A, and it comprises the upper cut-off knife sheet 1 be positioned at above exit slot and the lower cut-off knife sheet 2 be positioned at below exit slot, and upper and lower cut-off knife sheet is relative active state; Key of the present invention is:
This lower cut-off knife sheet 2 is made up of lower-left cut-off knife sheet 21 and bottom right cut-off knife sheet 22, and the joint of lower-left cut-off knife sheet 21 and bottom right cut-off knife sheet 22 supports due to support nail 23 and is connected.
The Shi Ziqi center, cutting edge edge 11 of wherein going up cut-off knife sheet 1 forms " V " type breach to two ends, and lower-left cut-off knife sheet 21 and the cutting edge edge 211,221 of bottom right cut-off knife sheet 22 are in straight line.
Coordinate shown in Fig. 6 to Fig. 9, when hand papercutter of the present invention carries out work, the action of cut paper relies on upper cut-off knife sheet 1 mutually to suit with lower cut-off knife sheet 2 effect reaching and cut off paper, and be (the cutting off to centre with both sides during cut paper) that realized with the penetraction depth of lower cut-off knife sheet 2 by upper cut-off knife sheet 1 for the function of full cut paper and half cut paper.When upper cut-off knife sheet 1 and lower cut-off knife sheet 2 can be discharged by the seam between the lower-left cut-off knife sheet 21 of lower cut-off knife sheet 2 and bottom right cut-off knife sheet 22 at the stress carrying out being formed when suiting action, thus reach upper and lower cut-off knife and can ensure all the time suitable to suit knife degree in the process of cutting a sheet of paper, the power that suits that left and right both sides when preventing involutory between upper bottom knife suit to centre interacts to the right and left, ensure the smooth and easy of cut paper action, and make the life-span of each cut-off knife sheet be greatly enhanced.
