Liquid spraying device of digital printing machine and control method thereof

Abstract

The invention provides a liquid spraying device of a digital printing machine and a control method of the liquid spraying device. According to the liquid spraying device of the digital printing machine and the control method of the liquid spraying device, a power mechanism is controlled to deliver compressed air into a liquid storage tank to press treating fluid in the liquid storage tank into a main pipeline, and then the treating fluid enters all branch pipelines, so that when first solenoid valves mounted at the outlet ends of all the branch pipelines are opened, the treating fluid is sprayed from nozzles mounted at the outlet ends of the first solenoid valves to the surface of a printing medium on a platform located below the nozzles. In this way, the treating fluid is automatically sprayed to the surface of the printing medium, it is guaranteed that the treating fluid sprayed onto the printing medium is uniform, time and labor are saved, and the treating fluid spraying efficiency is greatly improved.

Description

technical field [0001] The present invention mainly relates to the technical field of printing, and more specifically relates to a liquid spraying device of a digital printing machine and a control method thereof. Background technique [0002] The digital printing machine is a "non-contact" inkjet printing high-tech digital printing equipment, so it is not limited by any material, and can be printed on cotton, polyester, polyester-cotton blended, Lycra, silk, Color photoprinting on surfaces such as leather, denim, linen and other textiles to enhance the aesthetics of textiles. [0003] Wherein, when printing non-white textiles, it is necessary to print a layer of white ink on the textiles before printing specific patterns, and a layer of treatment liquid must be sprayed on the surface of the textiles before printing the white ink. In the prior art, the treatment liquid is usually put into a liquid spray device such as an electric watering pot or a manual spray gun, and then...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention proposes a digital printing machine liquid spraying device and its control method, which solves the problem that the existing liquid spraying device must be manually sprayed by the staff, which is time-consuming and laborious, and is often caused by the spraying. The technical problem of non-uniform pretreatment liquid sprayed on the surface of textiles due to the difficulty of controlling the liquid device
