A wallpaper printing device based on foaming ink

Abstract

The invention relates to the technical field of printing equipment, and discloses a wallpaper printing device based on foaming ink. The device is characterized in that a front pressing roller and a rear pressing roller are arranged on two sides above a printing roller, wherein and the front pressing roller and the rear pressing roller enable wallpaper at a printing part between the front pressingroller and the rear pressing roller to be tightly attached to the printing roller, so that reliable contact at the printing part is realized, and the printing quality and definition are ensured; an anti-slip assembly is capable of preventing from the sliding between wallpaper at the printing part and the printing surface of the printing roller during the printing operation, thus effectively improving the printing reliability, preventing from the problem of unqualified printing quality caused by the sliding, and preventing from the damage of the whole piece of wallpaper. The anti-slip assemblyis also capable of embossing the edge part of the wallpaper at the printing part, so that the edge part of the printed wallpaper can be torn along the embossed marks, and the requirement on later useis met, and the artistic performance is achieved; the operation is simple and convenient; later edge cutting process is saved; equipment is simplified; processes are decreased; and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a wallpaper printing device based on foaming ink. Background technique [0002] At present, for the printing of foam ink wallpaper, there are mainly two methods: jet printing and roller printing. The jet printing equipment has high requirements on the jet printing head, while the cost of the roller printing equipment is low. Therefore, at present, for general hair printing For the printing of bubble ink wallpaper, it is generally done by roller printing. Roller printing is to make the printing plate of the text and image to be printed first, install it on the printing machine, and then apply the ink to the place with the text and image on the printing plate by the printing machine, and then directly or indirectly transfer it to the wallpaper, and then Get wallpaper in the pattern you want. [0003] However, this method of roller printing requires a high matching betw...

Problems solved by technology

[0003] However, this method of roller printing requires a high matching between the rotation speed of the printing roller and the advance rate of the wallpaper, and the two can only advance synchronously. In actual operation, due to the operating error of the drive motor and the manufacturing error of the equipment etc., will easily lead to the difficulty of synchronizing the two, which will lead to printing overlap or intermittent problems during printing, and cause the entire surface of the wallpaper to appear uneven or even completely lose the printing effect of the required pattern, resulting in The entire wallpaper is scrapped, which leads to a decrease in the printing yield and affects printing costs and reliability
