Label printer

Abstract

The invention discloses a label printer. The printer comprises a housing and a cover body rotationally connected to the housing, a label roll mounting mechanism, an electric power mechanism and a printing head assembly are arranged in the housing, a rubber roller is arranged on the cover body, when the cover body covers the housing, the rubber roller is connected to the electric power mechanism, the rubber roller and a printing head ceramic plate are oppositely arranged, and the rubber roller rotates forwards and backwards under the action of the electric power mechanism, such that label paper comes out or retreats; and the printing head assembly comprises an anti-clamping piece arranged on a paper outlet side of the printing head ceramic plate, the edge of the anti-clamping piece is set to be of a fillet structure, and the fillet structure exceeds the top end of the printing head ceramic plate in a label paper feeding channel. According to the printer, by means of the anti-clamping piece, the defect that die cutting label paper is scraped up and cannot be normally printed during paper retreating can be overcome, the paper retreating success rate is greatly increased, waste of exposed labels after label consumables are arranged is avoided, and the cost is reduced; and through the fool-proof arrangement of a mandrel assembly, it can be guaranteed that a label roll is arranged without errors, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the field of label printers, in particular to a label printer. Background technique [0002] At present, printers are widely used in daily life, including places such as supermarkets, shopping malls, and homes, and printers are also tending to be miniaturized, such as price-setting machines used to print price tags in supermarkets and used to print dates and signs in homes. Label printers such as personalized labels, etc. Existing thermal printers can print required patterns by installing semiconductor heating elements on the print head, such as the ceramic sheet of the print head. During the printing process, the printing paper is set between the ceramic sheet of the printing head and the rubber roller, and the printing paper is driven by the rubber roller. The printing surface of the printing paper can be regarded as a smooth plane, and the contact surface between the printing paper and the rubber roller The contact surface...
