Spray head frame positioning device of continuous ink-jet printing production line, and control method thereof

Abstract

The invention relates to a spray head frame positioning device of a continuous ink-jet printing production line, and a control method thereof. The device comprises a left crossbeam lifting plate, a fixed plate, a right crossbeam lifting plate and a transmission mechanism. The device is characterized in that the left crossbeam lifting plate is provided with a fixed block A and a fixed block B, and the fixed block A and the fixed block B are respectively provided with a steel ball A and a steel ball B; the right crossbeam lifting plate is provided with a fixed block C, and the fixed block C is provided with a steel ball C; and the transmission mechanism comprises a nut, a leading screw, a worm and gear, a shaft coupling and a servo motor. The invention provides technical means of integral position adjustment of a large-span spray head frame; the parallelism requirement between a spray head and a fabric surface is effectively met, and the printing precision is ensured; in addition, manual adjustment is avoided, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to a kind of installation tool, more specifically, it relates to a continuous type inkjet printing production line nozzle frame positioning device and its control method. Background technique [0002] The continuous inkjet printing production line is equipped with nozzles in the entire printing width direction, and the nozzles are fixed at the bottom of the nozzle frame as a whole. In order to ensure printing accuracy, each nozzle and the surface of the fabric should be kept parallel during printing. Depends on the position of the nozzle holder, therefore, the overall position adjustment of the nozzle holder before printing becomes particularly important. [0003] For example, the publication date is October 15, 2014, and the publication number is CN203876384U Chinese patent, which discloses an improved digital printing machine. A nozzle controller and an inkjet positioning device, but the specific structure of the inkjet...

Problems solved by technology

[0003] For example, the date of publication is October 15, 2014, and the publication number is CN203876384U in the Chinese patent, which discloses an improved digital printing machine. Nozzle controller and inkjet positioning device, but the specific structure of the inkjet positioning device is not disclosed

Another example is that the publication date is March 13, 2013, and the Chinese patent with the publication number CN202782174U discloses a high-efficiency digital printing machine, which includes a frame, a cloth conveying device, an inkjet positioning calibration device and a printing Inkjet device, but the specific structure of the inkjet positioning calibration device is not disclosed

[0004] To sum up, for the printing of large and wide fabrics, there is currently no nozzle frame positioning device and its control method for the continuous inkjet printing production line with simple structure, reasonable design, and positioning and holding functions, so that the nozzle and the surface of the fabric are in the same position. Keep parallel when printing, so as to realize accurate printing and accurate color registration of CMYK four-color printing unit
