A thermal printer paper roll storage mechanism

Abstract

The invention discloses a thermal printer paper roll storage mechanism, which comprises a storage box and a roll paper outlet. One end of the inner cavity of the storage box is movably provided with a sliding plate, and one side of the sliding plate and the middle part of the other end of the inner cavity of the storage box pass through bearings. There is a connecting shaft for rotation connection, two telescopic assemblies are arranged at one end of the storage box, an extrusion assembly is arranged on the side wall of the storage box, a suction block is arranged on the side wall of the storage box above the roll paper outlet, and a suction block is arranged on the other end of the storage box. An exhaust fan is embedded on the top, and a rolling assembly is rotated in the roll paper outlet to facilitate the thermal printing roll paper to slide out. The present invention enables the slide plate to move left and right under the action of the telescopic assembly through the slide plate and the telescopic assembly, so that the connecting shaft on the slide plate can also move left and right, which is convenient for people to install the thermal printing roll paper on two On the connecting shaft, through the setting of the sliding plate, the thermal printing roll paper is limited to prevent the thermal printing roll paper from shaking.

Description

technical field [0001] The invention relates to a storage mechanism, in particular to a thermal printer paper roll storage mechanism. Background technique [0002] Thermal paper is also known as thermal fax paper, thermal recording paper, thermal copy paper, and in Taiwan, China, it is called thermal copy paper. Thermal paper is a kind of processed paper, and its manufacturing principle is to coat a layer of "heat-sensitive coating" (heat-sensitive color-changing layer) on high-quality base paper. Although there are more than a dozen kinds of chemicals used in this color-changing layer, there are at least the following compounds: leuco dyes, which have a wide variety of dyes, and fluorescent compounds are the most commonly used; Phenol and p-hydroxybenzoic acid; sensitizers account for less than 10%, which contain benzenesulfonamide compounds; fillers account for less than 50%, commonly used calcium carbonate (particles); adhesives account for less than 10%, Such as polyvi...
