Description

Printing device and film printer Technical Field The present invention relates to the field of printing apparatuses, and in particular, to a printing device and a film printer. Background In the related art, a medical image printer is generally a thermal film printer, and the working principle of the thermal film printer is that a semiconductor heating element is mounted on a printing head, and a required pattern can be printed after the printing head heats and contacts a thermal film, and the principle is similar to that of a thermal fax machine, and an image is generated by heating and generating chemical reaction in a film. When the medical thermo-sensitive film printer is used for printing, the printing head needs to keep a certain pressing force with the film to ensure the printing quality, however, the existing thermo-sensitive printer cannot adjust the pressing force, so that the reliable contact between the film and the printing head is affected, and the quality of the film printed is uneven. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the invention proposes a printing device in which the printing pressure can be adjusted. The invention also provides a film printer with the printing device. According to an embodiment of the first aspect of the present invention, a printing apparatus includes: a printhead assembly; The printing roller assembly is arranged below the printing head assembly; The pressure assembly is arranged on one side of the printing head assembly, which is away from the printing roller assembly; and the adjusting assembly can adjust the force applied to the printing head assembly by the pressure assembly. The printing device provided by the embodiment of the invention has at least the following beneficial effects: When the printing device works, when the pressure between the printing head assembly and the printing roller assembly needs to be regulated, the pressure assembly can be acted on by the regulating assembly, so that the force applied to the printing head assembly by the regulating assembly is regulated, and the pressure between the printing head assembly and the printing roller assembly can be regulated, so that the printing quality is improved.
