Abstract

The utility model relates to a paper knife for a lottery ticket printer, which is provided with a printer base (3) and a printing rotational frame (5), wherein the back of the printing rotational frame (1) is hinged with the base. The printed paper out part at the front of the printer is provided with the paper knife which comprises an upper blade (1) and a lower blade (2). The paper knife is characterized in that the upper blade (1) is installed on the printing rotational frame (5); the direction of the blade is consistent or almost consistent with the rotation direction of the printing rotational frame. The lower blade (2) opposite to the upper blade is installed on the base (3) or on a paper guide mechanism, and is in transmission connected with a gear which can drive the lower blade to move up and down. The lower blade is located at the front side of the upper blade when the lower blade is moved to an upper position. The paper knife changes the paper clamping direction, so that the separation direction of the upper blade and the lower blade which clamp the paper is perpendicular or almost perpendicular to the page orientation of thermal sensitive paper. In this way, the paper knife is not easy to be damaged even if an operator operates the paper knife ferociously.

Description

A kind of lottery ticket printer paper knife

Technical field

The utility model belongs to a kind of printing equipment, is specifically related to a kind of printing equipment that is used for print lottery tickets.

Background technology

The lottery ticket printer mainly is made up of base, printing equipment, form feeding device, several parts of paper knife, the printhead of printing equipment and print axis are contained in base respectively and print on the rotating turret, during printing, to print rotating turret puts down, make print axis and printhead clamp heat-sensitive paper, get final product print lottery tickets, paper has been used up, to print the rotating turret rotation and lift, can in the paper storehouse of base, put paper.In lottery ticket is printed; heat-sensitive paper is continuous paper roll, the action of all will cutting a sheet of paper of the intact lottery ticket of every printing, and paper knife is formed with the bottom knife that is contained on base or the paper guide by being contained in the cutter of printing on the rotating turret; be clipped in after paper between printhead and the print axis walks out; from down, pass by between the bottom knife, after every lottery ticket had been printed, the bottom knife insert orientation that makes progress moved; with the paper severing; along with the increase of access times, paper knife is understood rust, the situation of paperboard occurs through regular meeting.In the printer of design usually, referring to Fig. 1 a, it is consistent or roughly consistent with the direction of rotating turret to be contained in the direction of printing the cutter 1 on the rotating turret 5, so just be vertical or the approximate vertical direction with the rotation direction A of rotating turret, coil paper is passed by between cutter 1 and base-mounted bottom knife 2, when cutting a sheet of paper, bottom knife 2 is to cutter 1 motion, and cut from the paper feed downstream (for example upside of cutter 1 shown in Fig. 1 b) of cutter 1, with the paper severing, when jam condition takes place when, need to go up bottom knife separately, at this moment, because bottom knife is pressed on the cutter, be contained in the cutter of printing on the rotating turret and upwards opening on the direction be obstructed (referring to Fig. 1 b), so can not two blades be separated by rotating print carriage, normal program is by stirring travelling gear bottom knife to be return, two cuttves are separated, but in actual the use, certain operations personnel follow the line of least resistance, and usually are that hard two blades of exercising separate, in this case, the blade detaching direction is identical with the heat-sensitive paper page orientation, is easy to damage paper knife, causes printer not work.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of when handling jam condition the lottery ticket printer paper knife of the not fragile parts of cutting a sheet of paper.

The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with printer base (3), the printing rotating turret (5) that rear portion and base are hinged, the anterior printing of printer paper delivery partly is provided with the paper knife of being made up of cutter (1) and bottom knife (2), it is characterized in that: described cutter (1) is contained in to be printed on the rotating turret (5), insert orientation is consistent with the rotation direction of printing rotating turret or roughly consistent, the bottom knife relative with cutter (2) is contained on base (3) or the paper guide, and with can drive its gear drive that moves up and down and be connected, bottom knife moves to the front side that is positioned at cutter when upper.

The installation direction of the utility model paper knife cutter is consistent with the rotation direction of printing rotating turret or roughly consistent, thereby changed the holding paper direction, make the upper and lower blade detaching direction and heat-sensitive paper page orientation mutual vertical (or approximate vertical) of clamping paper, even operating personnel's operation is relatively more barbarous like this, also be difficult for causing the damage of paper knife.

The specific embodiment

This example is printed rotating turret 5 rear ends and base 3 links the point in O, cutter 1 is equipped with in the front portion, fixedly connected with the printing rotating turret in cutter top, the bottom is downwards facing to the base direction, make cutter and print the vertical or approximate vertical of rotating turret, this routine cutter 1 slightly tilts to the front lower place, this routine cutter is (a angle among Fig. 4,3-8 degree angle that turns forward with the rotation direction A (rotation tangential direction) that prints rotating turret, the common maximum in this angle should not surpass 10 degree), bottom knife 2 is vertically to being fixed on the base 3, its underpart with can drive its gear drive that moves up and down and be connected, bottom knife 2 moves to when upper, is positioned at the front side of cutter 1.

This routine print head cartridge is being printed rotating turret 5 front portions, and print axis is contained on the base 3, and a swing handle 7 is equipped with in the front portion of printing rotating turret 5, and shell fragment 6 is housed on the swing handle, and shell fragment 6 elasticity forward props up the rear surface of cutter 1 bottom.

Under print state, print rotating turret 5 and fall, printhead on the rotating turret and the print axis on the base are closed up, and clamp the temperature-sensitive coil paper, coil paper is after come out between printhead and the print axis, upwards pass through from cutter 1 front side, bottom knife 2 moves upward under the drive of travelling gear, can shear mutually with cutter, with the coil paper severing, when the holding paper situation takes place, the one, can bottom knife 2 be return downwards by stirring travelling gear, handle holding paper; The 2nd, can shell fragment 6 be unclamped by swing handle 7, cutter 1 and bottom knife are disengaged, handle holding paper; Even operating personnel not follow procedure handle affairs, hard row is handled, because the detaching direction of upper and lower blade and the rotation direction approximate vertical of rotating turret 5, so be difficult for causing the damage of blade.

The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; every foundation technical spirit of the present utility model all still belongs to the protection domain of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment did.
