Blast device for random marking apparatus

Abstract

The invention relates to a blast device for a random marking apparatus. The blast apparatus comprises one to N draught fans, one to N air channels, one to N air outlets and one to N valves. The blasting air is normal temperature air, hot air and cold air; the valve can be a single-way valve and a proportion valve; and wind speed and directions of the air outlet can be controlled by a controller and a sensor. The blast device can be applied to an anti-fake label marking stage and / or a drying stage; oil ink can be blasted; a position of the oil ink falling on medium and a shape of the oil ink falling on the medium can be effected; and meanwhile, the oil ink can be quickly dried.

Description

technical field [0001] The invention relates to a random marking device, in particular to a blowing device for the random marking device. Background technique [0002] The existing Chinese patent 2015201975795 proposes an anti-counterfeiting marking system, which can meet the needs of continuous production on the industrial assembly line and put random anti-counterfeiting marks on the products on the assembly line. [0003] The existing Chinese patent 2015201982286 provides an anti-counterfeiting marking device capable of making random anti-counterfeiting marks. [0004] In the above-mentioned existing label printing device, after the ink comes out of the ink outlet, it naturally falls on the medium, sometimes the ink will fly out of the marking area, the shape of the ink dot is relatively small, the area occupied by the ink dot is small, and the drying speed is slow; If, after the ink comes out of the ink outlet, with the assistance of the blower, the area where the ink do...

Problems solved by technology

[0004] In the above-mentioned existing label printing device, after the ink comes out of the ink outlet, it naturally falls on the medium, sometimes the ink will fly out of the marking area, the shape of the ink dot is relatively small, the area occupied by the ink dot is small, and the drying speed is slow; If, after the ink comes out of the ink outlet, with the assistance of the blower, the area where the ink dots fall is controlled; the ink dots with a large amount of ink are blown away, so that the shape of the ink dots is more complicated, and the drying speed is accelerated.
