Problems solved by technology

[0005] First, the heating contact area is small, and the temperature of the nozzle fluctuates greatly
The electric heating system generally uses a heating tube with a diameter of 3mm. Due to the small diameter of the heating tube, the contact area between the heating tube and the nozzle to be heated is small, and a good heating effect cannot be achieved.
On the other hand, during the heating process, the temperature of the nozzle is controlled by controlling the on-off mode of the heating tube, so that the temperature of the nozzle fluctuates greatly, and the local temperature of the nozzle will be too high or too low, which will affect the quality of the printed image;
[0006] Second, there are many wirings, and the wiring is complicated
The electric heating system is adopted, and heating pipes, temperature detectors, overheating

Embodiment Construction

[0038] Aiming at the problems of poor heating effect, complicated wiring and high cost in the existing electric heating system, the present invention provides a nozzle heating system for inkjet printers. The heating system is extended from the electric heating system, but adopts a The heating system is very different.

[0039] The heating method of the nozzle heating system provided by the present invention is: the water heated to a certain temperature is pumped into the water pipe installed on the nozzle of the inkjet printer through the rotary vane pump, and the nozzle is heated by circulating water with a certain temperature, instead of the prior art In each nozzle, heating pipes, thermistors and overheating protectors are installed to directly heat the nozzles; among them, the nozzles of the inkjet printers themselves are equipped with nozzle water pipes.

[0040] It can be seen from the above analysis that the key point to realize the present invention is to design a devi...

Abstract

A heating system for the jet head of ink jet plotter is composed of a water storage unit able to heat the water in it, a water tube of jet head, a rotary vane pump for pumping the hot water into said water tube of jet head in order to heat jet head, a liquid level sensor, and a diaphragm pump for automatically filling water in said water storage unit.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to a nozzle heating system of an inkjet printer. Background technique [0002] The inkjet printer is a printing device that prints large-scale color pictures such as advertisements and posters in an inkjet manner, and has been widely used at present. When the inkjet printer is in use, its nozzle can work well at a certain temperature and print out high-quality images. Therefore, the nozzle of the inkjet printer is equipped with a nozzle heating system to make it work at an appropriate temperature. [0003] At present, the electric heating system is generally used to heat the nozzle of the inkjet printer. The system includes a heating pipe, a temperature detector, an overheat protector and a temperature control circuit board. When the system is working, the heating pipe is energized to directly heat the nozzle. When the temperature of the nozzle reaches the set temperatur...
