Tax stamp automation printer

Abstract

The invention discloses a tax receipt automatic printer comprising a cabinet; one side of a printer body is provided with a first radiating tube and a second radiating tube; an air inlet tube is arranged in the cabinet; an air outlet tube is arranged in the cabinet; two ends of the first radiating tube are respectively connected with a soft tube; the second radiating tube is connected between theair inlet tube and the air outlet tube; a turbine is rotatably connected in the second radiating tube; the second radiating tube is rotatably connected with a first cam; the turbine and the first camare coaxially connected; the first cam abuts against the first radiating tube; a negative pressure blade is rotatably connected in the air outlet tube; the printer body is peripherally surrounded by aplurality of third radiating tubes connected in sequence; the bottom of the printer body is fixedly provided with an annular tube; a ventilation mechanism used for ventilating the third radiating tubes is arranged in the cabinet; compared with the prior art, the heat energy formed in the printer body can be timely radiated, thus preventing paper jam, and improving the printer body service life.

Description

technical field [0001] The invention belongs to the field of paper cutting equipment, and in particular relates to an automatic tax stamp printer. Background technique [0002] Dot matrix printers hit carbon paper with 24 needles in the print head to form fonts. In use, users can choose multi-part paper according to their needs. Commonly used multi-part paper includes 2-part, 3-part, and 4-part paper. , which also uses 6-page printer paper. The volume and size of the traditional dot matrix printer core are small and will not occupy too much space. However, when printing, because it will generate a lot of heat, if the heat is not dissipated in time, not only will the entire printer parts be in a long-term The high temperature state will cause certain damage to the parts, shorten the service life of the parts, and also cause the entire printer to freeze, which is easier to jam and cause printing interruption. [0003] In order to solve the above problems, the Chinese patent ...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves the problems in the prior art by setting up a fan, but the above scheme still has the following problems: the printer of the above scheme will generate a large amount of heat if it is used for a long time, and only fan heating cannot guarantee that the heat can be dissipated in time If it goes out, it will also cause the printer to jam or be in a high temperature state, which will also reduce the service life of the printer.
