Description

High-efficient full-half-cutting double-cutter structure and printer thereof

Technical Field

The invention relates to a high-efficiency full-half-cutting double-cutter structure and a printer thereof.

Background

Today, there are various types of micro printers that perform printing by pressing a heated thermal head against recording paper to leave a print trace on the recording paper. Micro printers are widely used for printing various labels, receipts, tickets, etc. The paper cutting state is commonly divided into full paper cutting and half paper cutting, wherein the full paper cutting refers to cutting all paper; the half-cut paper is a paper which is cut into small sections without being cut. Traditional automatic paper cutter structure of micro printer has multiple structure, nevertheless has the cutting and is not smooth and easy, influences performance scheduling problem. The following is a detailed analysis of the conventional guillotine structure:

referring to fig. 1 to 2, a first conventional guillotine structure: the cutting device is composed of a fixed blade 10 'and a movable blade 20', and the two cutting blades are in a relative movable state; wherein the cutting edge of the movable blade 20' is formed with a V-shaped notch 22' from the center thereof to both ends, and the cutting edge of the fixed blade 10' is formed in a straight line. The movable blade 20 'contacts the fixed blade 10', and both sides of the "V" notch 22 'form a cutting point a201' and a cutting point B202 'with the fixed blade 10', respectively, and the recording sheet is cut gradually from both sides to the center. When the cutting point a201' and the cutting point B202' move into the notch 21', a half-cut state is realized, and when the fixed blade 10' completely sinks through the notch 21', a full-cut function is realized. The cutting point A201 'and the cutting point B202' act simultaneously, and when the receiving is not uniform, the cutting point A201 'and the cutting point B202' interfere with each other, so that only one of the two cutting points can work, and the condition that one side is not cut exists.

Referring to fig. 3 to 4, the second cutter structure: the cutting device is composed of a fixed blade 10 'and a movable blade 20', wherein the two cutting blades are in a relative movable state; the edge of the movable blade 20"" is formed with a V-shaped notch 22 from the center to the two ends, the fixed blade 10 "is composed of a left blade 11" and a right blade 12", a gap 13 is left between the left blade 11" and the right blade 12", and the gap 13" and the notch 21 "on the movable blade 20" "are positioned in the same vertical direction. When the gap 13 ' enters the slot 21' to realize half-cut, the movable blade 20' moves continuously to ensure that the slot 21' is completely submerged by the gap 13 ', and the left and right blades 12 ' and the slot 21' pull the paper to realize full-cut function. The final connection point of the full cutting process is realized by tearing off, the material of the recording paper is variable, and even the gap 13 between the left and right blades 12' is also variable, so that the phenomenon of continuous cutting still occurs frequently.

Detailed Description

The invention is described in further detail below with reference to the drawings and the detailed description.

A printer comprises a shell, a printing head, a double-blade structure and a driving system, wherein a containing cavity is formed in the shell and used for containing recording paper, and the double-blade structure and the driving system are arranged in the shell. The double blade structure includes a fixed blade 10 and a movable blade 20, and the driving system is connected to the movable blade 20 for driving the reciprocating sliding of the movable blade 20. When printing, the recording paper is drawn out of the cavity, and the printing head is contacted with the recording paper to leave printing traces on the recording paper; subsequently, the recording sheet enters a double blade structure, and the movable blade 20 cuts the recording sheet in cooperation with the fixed blade 10.

Referring to fig. 5, the double-blade structure: the movable blade 20 is slidably disposed and rides on a surface of the fixed blade 10 while sliding, for cutting the recording sheet in cooperation with the fixed blade 10. The fixed blade 10 includes a left blade 11 and a right blade 12, the left blade 11 and the right blade 12 are arranged side by side, and a gap 13 is left between the left blade 11 and the right blade 12.

The movable blade 20 is provided with a cutting edge 22 on a side facing the fixed blade 10, and the edge of the cutting edge 22 is V-shaped from the center to both ends. The left blade 11 contacts the movable blade 20 to generate a cutting point a23, and the right blade 12 contacts the movable blade 20 to generate a cutting point B24. The cutting point a23 and the cutting point B24 gradually move toward the middle of the movable blade 20 to cut the recording paper, the left blade 11 and the right blade 12 do not affect each other due to uneven stress, smooth paper cutting operation is ensured, and the service lives of the fixed blade 10 and the movable blade 20 are prolonged.

Referring to fig. 5, the cutting edge 22 has a notch 21 in the middle, and the notch 21 is staggered from the gap 13. Preferably, the notch 21 has a first engagement point 211 and a second engagement point 212 facing the fixed blade 10, and both the first and second engagement points 212 are engaged with the left blade 11 or both the first and second engagement points 212 are engaged with the right blade 12 during cutting. The final connecting point of the recording paper is cut by one of the left and right blades 12, so that the problem that the influence factors are more and more continuous in the cutting mode by pulling is solved. The paper cutting machine has the advantages of being capable of well completing half paper cutting and full paper cutting, simultaneously having small paper cutting resistance, small mutual influence of the left blade 12 and the right blade 12, and being capable of smoothly cutting, and ensuring smooth completion of full paper cutting by cutting the last connecting point.

Referring to fig. 5, the left and right blades 12 have cutting edges 22 engaged with the movable blade 20, and the cutting edges 22 of the left and right blades 12 are linear. Preferably, the first engagement point 211 and the second engagement point 212 have different heights, and the two side edges of the cutting edge 22 have the same inclination. More preferably, the notch 21 is U-shaped, so that when half-cut paper is needed, the width of the connection point reserved by the recording paper is relatively stable, and the stability of the half-cut paper state is good.

Referring to fig. 5, preferably, the left blade 11 and the right blade 12 are symmetrically disposed, and two ends of the movable blade 20 are respectively provided with a guide portion, the guide portions extend toward the fixed blade 10, and the guide portions straddle the surface of the fixed blade 10.

And (3) cutting: the movable blade 20 is moved toward the fixed blade 10, so that the two side edges of the "V" shaped cutting edge 22 of the movable blade 20 form a cutting point a23 and a cutting point B24 with the left blade 11 and the right blade 12, respectively; the cutting point A23 and the cutting point B24 gradually move towards the notch 21, and cutting is achieved. When the cutting points a23 and B24 are not passing the fixed blade 10 and the notch 21 is not passing, half-cut paper is realized. When the movable blade 20 continues to move so that the entire notch 21 is submerged in the fixed blade 10, all-cut paper is obtained.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
