Marking ink-jetting device for calculation of length of piled paper on crossing bridge of corrugated board production line

Abstract

The invention relates to a marking ink-jetting device for calculation of the length of piled paper on the crossing bridge of a corrugated board production line, which comprises a nozzle body (1) arranged above a corrugated paper tape. The nozzle body (1) is provided with a mixing cavity (6) with the upper end used as an ink tube, the lower end of the nozzle body (1) is connected with a liquid cap (2) with an ink outlet (3); a cavity type atomization chamber (4) is arranged between the nozzle body (1) and the liquid cap (2); the lower end of the nozzle body (1) is also provided with a plurality of through hole type crushing small holes (5); and the mixing cavity (6) and the atomization chamber (4) are communicated with each other through the crushing small holes (5). The special ink-jetting device realizes the accurate calculation of the amount of piles paper on the crossing bridge of the corrugated board production line, and reduces the loss rate of the base paper by about 2 percent.

Description

technical field [0001] The present invention relates to an inkjet device. Specifically, it is a marking inkjet device used for measuring the length of accumulated paper on a bridge in a corrugated cardboard production line. Background technique [0002] At present, there are three main types of inkjet nozzles used in the flyover paper accumulation of corrugated paper production line: internal mixing type and external mixing type with compressed air pipeline and liquid pipeline, and atomization type with switch control. Regardless of the internal mixing type or the external mixing type, since there is no separate switch to control the closing of the liquid, when the solenoid valve connected to the liquid pipeline is closed, there is still a part of liquid between the solenoid valve and the nozzle, and the liquid lacks pressure. Or siphon factors form a stagnation, in the following period of time, this part of the liquid will continue to drip downward under the action of grav...

AI Technical Summary

Problems solved by technology

Since the liquid in this machine is liquid ink, if the ink dripped or sprayed on the corrugated paper is not exactly what the system needs, it will not only affect the appearance of the product, but also cause the sensor to send a wrong signal

The atomization type with switch control can meet the practical application of inkjet machine in structure, but the structure is complicated and the pipeline that needs to control the opening and closing of liquid separately is difficult to process and the cost is high
