Nozzle protective device for continuous type ink-jet printing production line and control method

Abstract

The invention discloses a nozzle protective device for a continuous type printing production line and a control method, which can perform early warning on the thickness of the fabric and the foreign matter on the surface and can adopt a corresponding means to protect the nozzle from damage. The nozzle protective device comprises a pedestal, a guiding belt, CMYK four groups of printing units, a beam synchronization elevating system, a three point positioning mechanism, a rack, an A group detection mechanism and a B group detection mechanism. The CMYK four groups of printing units comprise a printing unit C, a printing unit M, a printing unit Y and a printing unit K; the beam synchronization elevating system comprises a left transverse beam, a right transverse beam and a servo motor; the three point positioning mechanism comprises a flat bottom groove, a conical groove, a V-shaped groove, a steel ball seat A, a steel ball B and a steel ball C. The invention can automatically detect the thickness and the abnormal surface of the fabric, effectively guarantees the safety of the nozzle, prolongs the service life the nozzle, avoids the shut-down adjustment and improves the production efficiency.

Description

technical field [0001] The invention relates to an installation tool, more specifically, it relates to a nozzle protection device for a continuous inkjet printing production line and a control method thereof. Background technique [0002] There are joints between different batches of printing media, and the thickness of the joints is relatively thick. If it passes directly under the nozzle, it is very easy to directly collide with the nozzle and damage the nozzle; when the foreign matter on the surface of the fabric passes directly under the nozzle, it will also damage the nozzle. Therefore, it is particularly important to give early warning to the thickness of the fabric and foreign matter on the surface and take corresponding measures to protect the nozzle from damage. [0003] When the continuous inkjet printing production line is working, it is conveyed by the guide belt to the printing area under the nozzle to realize the printing function. Since the distance between th...

AI Technical Summary

Problems solved by technology

[0003] When the continuous inkjet printing production line is working, it is conveyed by the guide belt to the printing area under the nozzle to realize the printing function. Since the distance between the nozzle and the fabric is small, once the thickness of the fabric changes or there is foreign matter on the surface of the fabric, It is very easy to make the nozzle come into contact with the fabric, which will cause the nozzle to be easily damaged, which will affect the normal production and increase the defective rate of printed products

[0004] Although there is also a nozzle protection device now, as the publication date is June 12, 2013, and the publication number is CN202986341U, a Chinese patent discloses a digital printing machine printing nozzle protection device system, which can encounter obstacles when the printing nozzle stop immediately, effectively protect the print head, but cannot carry out continuous printing operation

[0005] In summary, there is currently no nozzle protection device and control method for a continuous inkjet printing production line that has a simple structure, a reasonable design, and can effectively detect changes in the thickness of fabric joints and foreign objects on the surface of the fabric, thereby realizing nozzle protection.
