Description

Page width printing device

This case relates to a printing device, especially a page width printing device.

The bearing mechanism of the printing platform of a common printer can be roughly divided into two forms. One is to use a moving device to reciprocally scan the ink cartridge disposed on the carrier mechanism along a horizontal axis direction to be printed. The paper is driven by the paper feeding mechanism and passes under the ink cartridge along a longitudinal axis, and the ink jet head ejects the ink in the ink cartridge to the surface of the paper to complete the printing operation. Since the inkjet head needs to move back and forth and the paper needs to be moved to print out a piece of the document required by the user, the time required for the movement plus the time required for the motor to go back and forth during the acceleration and deceleration makes the general inkjet printing The speed can only be between 30~35PPM (pages per minute) and cannot be improved.

Another type of printing platform carrying mechanism is fixed, and the printing head array of the printing platform having a width greater than or equal to the width of the printing paper is used to directly print the paper passing under the nozzle array, such printing The mode is called page-width array printing, which is to install a plurality of inkjet wafers on the bottom of the carrying mechanism of the printing platform, which can achieve certain convenience and efficiency in the printing process, but still have The following shortcomings to be improved:

1. Since a plurality of inkjet wafers are mounted on the bottom of the carrying mechanism of the printing platform, if one of the inkjet wafers is damaged, the overall printing quality will be affected, and the inkjet wafers cannot be separately replaced. The entire set of printing platforms is required for replacement.

2. The page-wide printing platform needs to be equipped with a complicated ink supply channel design in order to transport the ink to each ink chamber that communicates with each ink-jet wafer, which will increase the design and manufacturing costs. .

3. In order to manufacture a page-wide printing platform, it is necessary to arrange the ink-jet wafers one by one to the bottom of the supporting mechanism, so that the installation and layout of the control lines requires complicated manufacturing procedures, which inevitably leads to an increase in manufacturing man-hours and manufacturing costs.

4. In addition, the printing speed of the page-wide printing platform is faster than that of the conventional printing platform. Therefore, the paper feeding mechanism often causes paper jams, which may result in no improvement in printing quality and speed.

Therefore, how to develop a printing device to improve the printing speed of the prior art and the update of the entire printing platform is an urgent problem to be solved.

One of the main purposes of the present invention is to provide a page-wide printing device which utilizes a modular design in which a plurality of ink cartridges are independently carried on a printing platform, thereby solving the problem that the conventional technology requires the entire printing platform to be updated. The page-wide printing platform enables more convenient use and cost reduction in assembly, filling, and replacement.

Another main object of the present invention is to provide a page-wide printing device which uses a detachable inkjet head lap technique, a high-speed paper feeding mechanism, and an electronic component capable of processing images at high speed. The speed of the printed document is increased to above 60 PPM, and the page wide printing device has a cardboard removal mechanism for high-speed printing to achieve high-speed printing.

In order to achieve the above object, a broader aspect of the present invention provides a page width printing device comprising: a main body; at least one printing module is mounted on the main body and includes a printing platform a plurality of carrier heads and a plurality of ink jet head ink cartridges; a paper feeding mechanism is disposed on both sides of the main body body for conveying a column of printing medium in a distance between the printing module and the main body; One card The paper removal mechanism is disposed on both sides of the printing module for positioning the height of the printing module on the main body to facilitate the jamming condition.
