Large-breadth portable inkjet printer

Abstract

The invention provides a large-breadth portable inkjet printer. The inkjet printer comprises an omnidirectional platform, wherein omnidirectional wheels are arranged at the bottom of the omnidirectional platform, and a single-chip microcomputer controller, a stepping motor, an obstacle detection sensor, an inkjet device and a battery supplying power to the inkjet printer which are installed on theomnidirectional platform, wherein one end of the stepping motor is connected with the single-chip microcomputer controller and controlled by the single-chip microcomputer controller, the other end ofthe stepping motor is connected with the omnidirectional wheels and controls the omnidirectional wheels to move, the obstacle detection sensor is connected with an IO port of the single-chip microcomputer controller and serves as input of the single-chip microcomputer controller, and the inkjet device is connected with an IO port of the single-chip microcomputer controller, serves as an output ofthe single-chip microcomputer controller, and is controlled by the single-chip microcomputer controller. The inkjet printer is advantaged in that the inkjet printer can flexibly walk on printing paper, advertisements, posters or the ground with extra-large breadth, steering is performed under zero turning radius, inkjet printing with unlimited breadth of characters or patterns is performed, and the inkjet printer is convenient and simple to operate, high in inkjet printing quality, adjustable in inkjet ink drop size and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to an inkjet printer capable of printing characters and pictures on large-format paper, canvas, advertising paper, posters or the ground. Background technique [0002] With the improvement of people's living standards, the demand for large-format advertisements, posters or ground signs in the market is increasing. At present, the format size of inkjet printing is limited by the mechanical size of inkjet printers or flatbed printers. Generally, the maximum width can reach 5 meters, and these inkjet printing equipment are too large to be portable. The Chinese patent "Intelligent inkjet car" with the notification number CN204263733U includes a frame and a single-chip microcomputer. Wheels are arranged on the left and right sides of the bottom of the frame, and infrared tracking sensors and wheel stepping motors are arranged on the sides of the wheels. The upper part of the fra...

AI Technical Summary

Problems solved by technology

The quality and width of the black line directly affect the printing accuracy, so the drawing of the black line is highly demanding and difficult, and the black line is additional content compared to the inkjet content of the advertising banner, which needs to be cut out later. An additional process was added

Secondly, the device adopts the ordinary wheel differential method to realize inkjet line change, and the turning radius is large, which is not conducive to the control of line spacing

Finally, the nozzle used in this device is a siphon nozzle. If the nozzle is placed too low, a siphon phenomenon will occur, and the ink will flow out by itself. In addition, the size of the ink droplet cannot be controlled.
