Problems solved by technology

When the design of this structure and the method of paper feeding are used in practice, the uppermost layer of the stacked label paper 03 will be pulled by the printer and bend when it moves forward, and the label 04 is shorter than the label paper 03. Short and thick, generally do not bend along with the label paper 03, so that there will be a mutual separation force between the label paper

Example Embodiment

[0017] The present invention will be further described in detail below in conjunction with the drawings.

[0018] Attached figure 2 And image 3 , A method to prevent label paper degumming and paper jams of thermal printers. When feeding paper, the printer adopts the paper feeding method of reversing the label paper 3 to feed the paper, that is, looking in the paper feeding direction A, the label paper 3 is on the top , Label 4 is on the bottom; in this paper feed mode, the position of the printer's paper feed roller and print head is changed, that is, the printer's paper feed roller and print head are set on the side near the bottom of the printer, and the print head prints The orientation is toward the top of the printer.

[0019] Preferably, a mirror 5 is also provided at the paper inlet 2 of the printer, and the reflective surface of the mirror 5 is directed upwards to the bottom of the label paper 3 at the paper inlet 2 for reflecting the label paper 3 Information on label ...

Abstract

The invention discloses a method for effectively preventing label paper from separating from a label and paper jamming of a thermal printer. The method comprises the following steps that when the paper is fed into the printer, a paper feeding mode of reversing the label paper (3) is adopted to feed the paper, namely, the label paper (3) is arranged above and the label (4) is arranged below when aworker views in the paper feeding direction; and under the paper feeding mode, the positions of a paper feeding rotating wheel and a printing head of the printer are changed in a matched mode, namely,the paper feeding rotating wheel and the printing head of the printer are arranged on one side close to the bottom of the printer, and the printing direction of the printing head faces the top of theprinter. A paper inlet (2) of the printer is also provided with a mirror (5), and the reflecting surface of the mirror (5) is upwards aligned to the lower surface of the label paper (3) at the paperinlet (2), and is used for reflecting the information of the label (4) on the label paper (3). The mirror (5) is of a drawer-type structure and is arranged at the bottom of the printer.

Description

technical field [0001] The invention relates to the technical field of thermal printers, in particular to a method for preventing label paper degumming and jamming of thermal printers. Background technique [0002] At present, thermal printers are widely used. The principle of thermal printers is: cover a layer of transparent film on a light-colored material (usually paper), and heat the film for a period of time to turn it into a dark color (usually black, but also blue). ). The image is created by applying heat, which creates a chemical reaction in the film. This chemical reaction is carried out at a certain temperature. High temperatures accelerate this chemical reaction. When the temperature is lower than 60°C, it takes quite a long time, even several years, for the film to become dark; and when the temperature is 200°C, this reaction will be completed within a few microseconds. The thermal printer selectively heats the thermal paper at certain positions, thus produc...
