Page-width array printing device

Abstract

The invention relates to a page-width array printing device which comprises a main machine body and at least one printing module, paper feeding mechanisms and paper jam eliminating mechanisms, wherein at least one printing module is formed on the main machine body and comprises a printing platform, a plurality of bearing seats and a plurality of ink gun ink cartridges, the paper feeding mechanisms are formed on the two sides of the main machine body and are used for conveying a printing medium to a space between the printing module and the main machine body, and the paper jam eliminating mechanisms are formed on the two sides of the printing module, are used for locating the height of the printing module formed on the main machine body, and are beneficial for eliminating a paper jam condition.

Description

technical field [0001] The invention relates to a printing device, especially a page-width printing device. Background technique [0002] The carrying mechanism of the printing platform of a common printer can be roughly divided into two types. One is to use a moving device to move the ink cartridge arranged on the carrying mechanism back and forth along a horizontal axis, and the paper to be printed is moved by Driven by the paper feeding mechanism, it passes under the ink cartridge along a longitudinal axis, and the ink in the ink cartridge is sprayed onto the surface of the paper by the inkjet head to complete the printing operation. Since the inkjet head needs to move back and forth and the paper needs to be moved to print a graphic document required by the user, and the time required for the movement plus the acceleration and deceleration time required for the motor to go back and forth, the general inkjet printing speed is only It can be between 30-35PPM (pages per mi...

AI Technical Summary

Problems solved by technology

[0004] 1. Since multiple inkjet chips are installed and arranged at the bottom of the bearing mechanism of the printing platform, if one of the inkjet chips is damaged, it will affect the overall printing quality, and each inkjet chip cannot be replaced individually. Replacement of the whole printing platform

[0005] 2. In order to deliver the ink to the ink chambers connected to the inkjet chips, the page-wide printing platform needs to be equipped with a complex ink supply channel design, which will increase the design and manufacturing costs

[0006] 3. In order to manufacture a page-wide printing platform, it is necessary to install and arrange the inkjet chips one by one to the bottom of the supporting mechanism. In this way, the placement and layout of the control circuit requires more complicated manufacturing procedures, which will inevitably increase the manufacturing hours and manufacturing costs.

[0007] 4. In addition, because the printing speed of the page-wide printing platform is faster than that of the known reciprocating printing platform, it is known that the paper feeding mechanism often produces paper jams, resulting in the inability to improve the printing quality and speed.

[0008] Therefore, how to develop a printing device to improve the printing speed of the known technology and the update of the entire printing platform is an urgent problem to be solved at present.
