Abstract

The invention discloses a cutting device for a label medium of a handheld label printer. The cutting device comprises a base, a cutting mechanism and a paper pressing mechanism, wherein the base is provided with a guide groove and a transverse groove, the cutting mechanism comprises a push rod, a stepped movable blade and a static blade, and a blade of the stepped movable blade is opposite to a blade of the static blade; the stepped movable blade is arranged in the guide groove of the base; the stepped movable blade is provided with a rivet, the push rod is provided with a chute, and the rivet is extended into the chute and is connected with the push rod in a sliding manner; the push rod is connected with the base in a sliding manner, and the static blade is fixed above the transverse groove. When a cutting edge adopting the stepped movable blade is moved from a non-cutting position to a cutting position and is in contact with the label medium, the cut label medium is compressed by the both ends of the stepped movable blade firstly, so that looseness of the label medium is effectively avoided, and the stepped movable blade integrally penetrates through the label medium, so that effective cutting is realized.

Description

technical field [0001] The invention relates to components of a printer, in particular to a label medium cutting device of a hand-held label printer. Background technique [0002] Many handheld label printers have employed various devices and methods for separating printed and unprinted label media. Among them are US Patent No. 4,844,629, author Hoyt's invention, which can be used to manually tear off label media with serrated edge slots and US Patent No. 5,078,523, which uses a motor to control the movement of the blade. The more complex cutting device. In addition, there is also a V-shaped blade invented by Chinese patent 99806715. [0003] The cutting device of the handheld label printer needs to quickly and neatly separate the printed label medium from the unprinted label medium without breaking the wires, so as to reduce the burden on hands and ensure productivity. These existing technologies either leave uneven burrs after tearing off the label medium, which affects ...
