Embodiment

[0028] Example: such as Figures 1 to 9 As shown, the present embodiment provides a thermal printer, which includes a thermal sheet fixing structure, and the thermal sheet fixing structure includes an upper cover 4, a lower cover 3 assembled and connected to the upper cover 4 through positioning posts 6, the upper cover 4 and the lower cover 4. The covers 3 can be rotated relative to each other through the positioning post 6 to realize opening or closing of the upper cover. The upper cover is equipped with a rubber roller bonding device, which is located on the side of the upper cover close to the lower cover. The rubber roller bonding device includes two shaft sleeves symmetrically arranged through the bracket and a rotatable rubber roller between the two shaft sleeves. , the rubber roller is used to press the thermal paper to the thermal sheet. The lower cover is provided with a heat sink 2 and a hook 7, and the heat sink 2 is provided with a thermal sheet 1, the heat sink ...

Abstract

The invention relates to the technical field of printing equipment, and discloses a fixing structure for a thermosensitive sheet and a thermosensitive printer. The fixing structure for the thermosensitive sheet comprises an upper cover and a lower cover connected with one end of the upper cover, wherein the upper cover can be opened or closed relative to the lower cover; and the upper cover is provided with a rubber roller attaching device, and the lower cover is provided with the thermosensitive sheet. The fixing structure is provided with a positioning device which enables the rubber roller attaching device to be positioned at a fixed position when the rubber roller attaching device is pressed downwards, so that the width of a gap between the rubber roller attaching device and the thermosensitive sheet is kept consistent, and the phenomenon of poor printing caused by uneven stress due to elastic deformation is avoided.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a fixing structure of a thermal sheet and a thermal printer. Background technique [0002] At present, most of the pressing methods of thermal sheets of printers on the market use springs or shrapnels to directly apply pressure to the thermal sheets to make them bond to thermal paper and rubber rollers, but springs or shrapnels are prone to damage caused by external forces. Corresponding deformation, changing the pressure, easy to produce uneven pressure, resulting in uneven heating of thermal paper, resulting in poor printing. In addition, due to the substandard precision or deformation of printer parts, it may also lead to misalignment, resulting in inaccurate printing positioning, resulting in poor printing, high after-sales failure rate and scrap rate of printing equipment, and high production costs. Contents of the invention [0003] The technical problem to be...
