TECHNICAL FIELD

[0001] The utility model relates to a printer technical field especially a printing platform heating device for printer. BACKGROUND

[0002] In the field of inkjet printing, accurate control of the temperature of the printing platform plays a decisive role in ensuring the printing quality. During the process of the inkjet head spraying ink to form patterns or characters on the printing medium, the temperature condition of the printing platform will directly affect the printing quality of the inkjet head ink.

[0003] If the temperature of the printing platform is too low, the fluidity of the ink will be poor, resulting in poor spreading of the ink on the printing medium, and phenomena such as ink droplet accumulation and unclear pattern edges may occur, reducing the resolution and fineness of the printing.

[0004] Moreover, the temperature of the printing platform of most printers on the market and the temperature of the printing environment have a large difference, which is due to the fact that most printers have built-in constant temperature devices, but only use them for the printing platform itself. During the printing process, the temperature of the ink and paper basically does not change, which also leads to the above-mentioned problems. SUMMARY

[0018] As Figures 1-2 shown in the utility model discloses a printing platform heating device for printer, which comprises a printing platform 1 and a printing trolley arranged above the printing platform, a nozzle (the printing trolley is omitted in the drawing) is arranged on the printing trolley, one side of the printing platform 1 is provided with a heating controller 2, the heating controller 2 is electrically connected with a heating device, the heating device is arranged on the same side of the printing platform 1 as the heating controller 2, and one end of the heating controller 2 is externally connected with a remote control switch 6 through an electric wire.

[0019] Preferably, the other side of the printing platform 1 is provided with a temperature sensor 7, which is signal connected with the heating controller 2.

[0020] Preferably, the heating device is an electric heating tube 3.

[0021] Preferably, the electric heating tube 3 has two roots, the electric heating tube 3 is installed on a fixing frame 5, and the fixing frame 5 is fixedly connected with the printing platform 1.

[0022] Preferably, the length of the electric heating tube 3 is greater than the length of the printing paper 4.

[0023] As Figure 3The heating controller 2 shown in the utility model includes NTC resistance, main control CPU, transformer and external power line, and the main control CPU is respectively connected with NTC resistance, electric heating tube 3 and temperature sensor 7.

[0024] Among them, the transformer of the utility model converts the voltage of the external power supply into the voltage suitable for the operation of each component inside the heating controller 2. Because different components may require different voltage levels, the transformer can provide stable and required voltage to ensure the normal operation of each component. Based on the principle of electromagnetic induction, the input high voltage is converted into lower and stable output voltage by changing the turns ratio of the transformer to supply power to the NTC resistance, main control CPU and other components.

[0025] Preferably, the NTC resistance has at least two, which is temperature detection resistance, as temperature detection resistance, is used for real-time detection of the temperature of the printing platform. The resistance value of the NTC resistance decreases with the increase of temperature, and the current temperature information can be indirectly obtained by measuring the change of the resistance value.

[0026] Working principle: at least two NTC resistances are distributed at appropriate positions of the printing platform to obtain more accurate temperature data. When the temperature of the printing platform changes, the resistance value of the NTC resistance changes accordingly, and the main control CPU calculates the temperature of the current printing platform 1 by detecting the voltage change of the two ends of the NTC resistance and using the pre-set resistance-temperature corresponding relationship.

[0027] Preferably, the heating controller 2 further comprises two relays, and the two relays are respectively electrically connected with the two electric heating tubes 3.

[0028] In the utility model, the main control CPU outputs control switch signals to the two relays to open the relay switch; then 220V alternating current is loaded into the electric heating tube 3, at this time the platform 1 starts heating;

[0029] At the same time, the two temperature detection NTC resistances read the temperature value of the surface of the platform 1 at the same time, and the temperature sensor 7 sends the environmental temperature at the same time. When the environmental temperature is lower than the temperature of the printing platform 1, the electric heating tube 3 near the printing platform 1 stops working, and the other electric heating tube 3 continues to work to heat the printing environment (the environment where the printing paper 5 is located);

[0030] If the temperature values of the two reach the expected temperature value, then the heating will be stopped at this time;

[0031] If it is detected that the temperature value of the platform 1 is lower than the expected value, then the main control CPU will output the relay control signal again to heat again; in this way, the temperature of the printing platform 1 of the machine and the temperature of the printing environment can be kept at a certain specific temperature environment.

[0032] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application.
