Cleaning device of spray head of ink-jet printer

Abstract

The invention discloses a cleaning device of a spray head of an ink-jet printer. The cleaning device comprises a cleaning device main body and a cleaning table; the cleaning table is mounted in the bottom of the cleaning device main body. The cleaning device also comprises a spray head fixing tank, a spray head, a side guide rail, a slide, a movable cross beam, an air cylinder, a piston rod, a cleaning motor, a rotary shaft, a cleaning hairbrush and a washing pipe. The cleaning device disclosed by the invention is reasonable and simple in structure, low in cleaning cost and convenient to use,and improves the cleaning speed and the cleaning quality of the spray head of the printer effectively by combining scrubbing with washing. A plurality of reset springs are mounted on the cleaning hairbrush, so that the using flexibility and elasticity of the cleaning hairbrush can be improved effectively, and a smooth surface in the spray head is prevented from being worn in a cleaning process. Cleaning water is recycled, so that water resources are saved and the cleaning cost of the spray head of the printer is lowered; a heater is mounted on a water inlet pipe to heat the cleaning water, andprinting ink which is dry and hard on the inner wall of the spray head is melted conveniently by means of the hot water, so that the cleaning speed is further accelerated.

Description

Technical field: [0001] The invention relates to the technical field of inkjet printers, in particular to a cleaning device for nozzles of inkjet printers. Background technique: [0002] Inkjet printers can be divided into solid inkjet and liquid inkjet according to the working principle, and liquid inkjet can be divided into bubble type and liquid piezoelectric type. Nozzle clogging is one of the common faults of inkjet printing. The nozzle clogging will lead to a decline in printing quality. If the clogging is serious, many horizontal lines or even blurred printing will appear on the printing screen. Therefore, it is necessary to clean the nozzles of inkjet printers regularly, but the existing The cleaning device of the nozzle of the inkjet printer adopts the method of showering. It is difficult for the shower water to rinse the ink that has dried on the inner wall of the nozzle. It is longer, which affects the normal operation of the inkjet printer, and the scraper on th...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a cleaning device for nozzles of inkjet printers in order to solve the above problems, which solves the problem that the cleaning device for nozzles of existing inkjet printers is carried out by showering, and the shower water is difficult to dry on the nozzles. The ink on the inner wall is washed clean. On the one hand, it affects the cleaning quality of the nozzle of the inkjet printer. On the other hand, the cleaning time of the nozzle is longer, which affects the normal operation of the inkjet printer. The scraping of the ink can easily damage the smooth surface of the inner wall of the nozzle, which will lead to the increase of the hydrophilic ability of the inner wall of the nozzle and cause the problem of cross-color of the nozzle
