Scissors type integral cutter structure and printing device

Abstract

The invention discloses a scissors type integral cutter structure and a printing device. The scissors type integral cutter structure is arranged on a cutter support and comprises a fixed blade, a movable blade and a hinge pin, the movable blade is movably connected with the fixed blade, the hinge pin is used for connecting the movable blade and the fixed blade, and the fixed blade is fixedly connected with the cutter support and provided with a fixing end connected with the hinge pin in a hinged manner. The scissors type integral cutter structure adopts the same supporting carrier and is connected with the supporting carrier by the riveted hinge pin a hinged manner, paper cutting frequency can reach 2000000 at least, and the service life of the cutter structure is greatly prolonged. The printing device is further provided with a paper holding device, the paper holding device only conveys printing paper separated from a printing rubber wheel to a paper outlet at the outermost end after the paper is cut, the printing paper is prevented from being manually drawn before a receipt is completely printed, further, damage to a printing core is reduced, the service life of a receipt printer is prolonged, the failure rate of the receipt printer is reduced, and the maintenance cost of the receipt printer is lowered.

Description

technical field [0001] The present invention relates to a cutter structure and printing equipment for a printer, more specifically to a printing paper cutter mechanism with an integral structure in which the fixed blade and the movable blade adopt the same fixed body, and a printing device composed of it . Background technique [0002] The cutter structures of printers (mainly bill printers) in the prior art include scissor-type structures and sliding-type structures. The fixed blade and the movable blade are positioned on the carrier, and the hinged connection between different carriers is used to realize the positioning of the fixed blade and the movable blade. However, its disadvantage is that the life is short, and the fixed blade and the movable blade are prone to damage. However, in actual use, the probability of paper jams is not high. Even if a paper jam occurs, the printing paper can be easily taken out without separating the fixed blade from the movable blade. ...
