Temperature control device and control method of thermosensitive printing head for printing system

Abstract

The invention discloses a temperature control device and control method of a thermosensitive printing head for a printing system. The device comprises a printer; a printing head is installed on one side of the printer; a first shell is disposed one one side of the printer; a temperature sensor is installed one one side of the printing head, and a first heater is installed one one side of the interior of the printing head; and a second heater is mounted on one side of the interior of the printing head; During use of the temperature control device and control method of the thermosensitive printing head for the printing system, if a central processing unit judges that the temperature input by a user is too high, a fixed value is transmitted to a controller, the controller controls an alarm togive an alarm, the user is promoted to perform voltage switching work, a fixed block on a second L-shaped rod is pressed down, the second L-shaped rod enters a first hole groove, one end of the second L-shaped rod slides into a second hole groove, a second contact is enabled to make contact with a third contact, voltage switching is conducted, the situation that the first heater and the second heater cannot reach the designated temperature due to the voltage problem is prevented, and manual power regulation and control are facilitated.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for printers, in particular to a temperature control device and a control method for a thermal print head used in a printing system. Background technique [0002] The printer is one of the output devices of the computer. It is used to print the computer processing results on the relevant media. There are three indicators to measure the quality of the printer: printing resolution, printing speed and noise. There are many types of printers. There are striking actions, divided into impact printers and non-impact printers, according to the structure of printed characters, divided into full-size character printers and dot-matrix character printers, according to the way a line of characters is formed on paper, divided into serial printers and line printers Printers, according to the technology used, are divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, lig...

Problems solved by technology

[0003] China's public authorized invention: CN201510505603.1 discloses a printing device and a control method for the printing device. This invention keeps the print head at a constant temperature at different background temperatures by continuously updating the background temperature. However, when the invention is in use, its overall power is controlled by The power control unit is used for control. If the system fails, it is not convenient to manually adjust the power. Therefore, a temperature control device and control method for a thermal print head used in a printing system are proposed.
