Abstract

The invention discloses an automatic paper-cutting knife structure of a printer, which is arranged at a paper outlet of the printer. The automatic paper-cutting knife structure of the printer comprises an upper cutting knife blade at an upper part and a lower cutting knife blade at a lower part, wherein the lower cutting knife blade is formed by butting a left lower cutting knife blade and a right lower cutting knife blade. In the invention, as the lower cutting knife blade of a paper-cutting knife is divided into a left blade body and a right blade body from one blade, when the printer cuts paper, the butting position of the left lower cutting knife blade and the right lower cutting knife blade can release a stress generated by butting when the upper cutting knife blade and the lower cutting knife blade butt to cut, the resistance for cutting the paper can be reduced, and the left lower cutting knife blade and the right lower cutting knife blade cannot mutually influence, thus the paper-cutting motion is smooth and the service life of the cutting knife blades is greatly prolonged.

Description

The automatic hand papercutter structure of printer

Technical field

The present invention relates to printer unit, be meant the automatic hand papercutter structure of a kind of printer especially.

Background technology

At present, the mini-printer application places is very extensive, and the accuracy of its every function is the guarantee that increases its service efficiency.

Traditional automatic hand papercutter structure of mini-printer that is used for, as shown in Figure 1, 2, this automatic hand papercutter structure is provided in a side of the exit slot place of printer, and it is by last cut-off knife sheet 1 ' and following cut-off knife sheet 2 ' formation, and two cut-off knife sheets are relative active state; The cutting edge edge 11 ' of wherein going up cut-off knife sheet 1 ' is that oneself wherein forms " V " type breach in the mind-set two ends, and the cutting edge edge 21 ' of following cut-off knife sheet 2 ' is to be straight line.The action of cut paper is that cut-off knife sheet 1 ' is gone up in dependence and following cut-off knife sheet 2 ' suits the effect that reaches the cut-out paper mutually, and be that penetraction depth by last cut-off knife sheet 1 ' and following cut-off knife sheet 2 ' realizes that full cut paper herein is meant paper is all cut off for the function of full cut paper and hemisection paper; And hemisection paper is meant and will leaves a little disconnected cut sample attitude that do not have in the middle of the paper.

But but there are the following problems for this traditional automatic hand papercutter structure:

1, paper can't be cut off during full cut paper, influence serviceability;

2, it is limited to cut the life-span, and cut paper is smooth and easy inadequately.

Studying carefully its reason that produces above-mentioned two problems is because in the cut paper process, last cut-off knife sheet 1 ' and all extruding in the middle of each cut-off knife sheet of the stress of following cut-off knife sheet 2 ' when suiting, cause resistance very big, particularly cutting edge edge 21 ' is the following cut-off knife sheet 2 ' of straight line, and its formed resistance can be bigger; If each cut-off knife sheet left and right sides elastic force control has deviation slightly, just can influence each other, to such an extent as to paper can't be cut off.

Summary of the invention

The purpose of this invention is to provide the automatic hand papercutter structure of a kind of printer, it can guarantee the smoothness and stability of cut paper, the service life of guarantee cut-off knife sheet.

For achieving the above object, solution of the present invention is:

The automatic hand papercutter structure of a kind of printer is provided in a side of the exit slot place of printer, and it comprises cut-off knife sheet and following cut-off knife sheet; Wherein: this time cut-off knife sheet is to be docked with two of bottom right cut-off knife sheets by lower-left cut-off knife sheet to form, and joint is supported by a nail and connects.

The described cutting edge edge of going up the cut-off knife sheet is to form " V " type breach from mind-set two ends wherein, forms a short slot in the middle of this breach.

After adopting such scheme, two lamellar bodies about hand papercutter of the present invention will descend the cut-off knife sheet to be decomposed into by a slice.When lower-left cut-off knife sheet and bottom right cut-off knife sheet and last cut-off knife sheet were done the cut paper action, the resistance of cut paper can reduce, about following cut-off knife sheet can not influence each other, and the cut paper action is very smooth and easy, also makes the life-span of each cut-off knife sheet be greatly enhanced.

The specific embodiment

Extremely shown in Figure 9 as Fig. 3, the present invention has disclosed the automatic hand papercutter structure of a kind of printer, it is arranged on the exit slot place of printer prints module A, and it comprises last cut-off knife sheet 1 that is positioned at the exit slot top and the following cut-off knife sheet 2 that is positioned at the exit slot below, and the cut-off knife sheet is relative active state up and down; Key of the present invention is:

This time cut-off knife sheet 2 is to be made of lower-left cut-off knife sheet 21 and bottom right cut-off knife sheet 22, and lower-left cut-off knife sheet 21 supports owing to a nail 23 with the joint of bottom right cut-off knife sheet 22 and is connected.

The cutting edge edge 11 of wherein going up cut-off knife sheet 1 is that oneself wherein forms " V " type breach in the mind-set two ends, and the cutting edge edge the 211, the 221st of lower-left cut-off knife sheet 21 and bottom right cut-off knife sheet 22 is straight line.

Cooperate Fig. 6 to shown in Figure 9, when hand papercutter of the present invention carries out work, the action of cut paper is rely on to go up cut-off knife sheet 1 to suit mutually with following cut-off knife sheet 2 and reach the effect of cutting off paper, and is (the cutting off to the centre with both sides during cut paper) that the penetraction depth by last cut-off knife sheet 1 and following cut-off knife sheet 2 realizes for the function of full cut paper and hemisection paper.The stress that when last cut-off knife sheet 1 and following cut-off knife sheet 2 are suiting action, is forming can by under the lower-left cut-off knife sheet 21 and the release of the seam between the bottom right cut-off knife sheet 22 of cut-off knife sheet 2, thereby reach cut-off knife up and down and in the process of cutting a sheet of paper, can guarantee the suitable cutter degree that suits all the time, prevent from fashionable left and right both sides between the blade are up and down interacted to the right and left to the power that suits that the centre suits, guarantee the smooth and easy of cut paper action, and make the life-span of each cut-off knife sheet be greatly enhanced.
