A printing device with automatic adjustment function

Abstract

The invention discloses a printing device having an automatic adjusting function; and the printing device comprises image sensors, a control unit, an adjusting mechanism, a frame, a round net and a guide belt mechanism. The guide belt mechanism comprises printing guide belts, a first guide belt wheel and a second guide belt wheel; and the printing guide belt at the upper side is horizontal. The round net is rotationally and horizontally mounted on the frame, and is positioned above the printing guide belts. The adjusting mechanism comprises a lateral adjusting shaft and a pressure adjusting wheel; and a printing round net motor set and the round net are in transmission connection. The pressure adjusting wheel is a cam or an eccentric wheel. The pressure adjusting wheel and a pressure adjusting wheel motor set are in transmission connection. The image sensors are fixedly mounted on the frame, are positioned at the two sides of the round net, and are used for obtaining image signals of cloth at the two sides of the round net. The image sensors are electrically connected with the control unit; and the control unit is used for analyzing and judging the cloth image signals and outputting control signals to the adjusting mechanism. The printing device can monitor broken figures of the round net, and adjusts through the adjusting mechanism to improve the printing precision.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing equipment, in particular to a printing device with an automatic adjustment function. Background technique [0002] The printing and dyeing industry occupies an important position in my country's national economy. At present, the rotary screen printing machine is still the main printing equipment, and its annual printing output accounts for more than 60% of the total printing output of various printing machines. However, the alignment accuracy of the rotary screen printing machine is not very high. It is mainly affected by a series of factors such as the wear of the transmission mechanism parts, the looseness of the alignment gear, and the deformation of the fabric in the actual production process. The phenomenon of "wrong flower" or "running flower" not only reduces the printing accuracy, but also limits the printing speed. [0003] In the process of textile printing production, the ...

AI Technical Summary

Problems solved by technology

Due to the large error in manual observation and judgment, low accuracy of alignment, and high labor intensity, especially when the pattern is complex, the color is multi-colored, the equipment is running for a long time, and the equipment is running at high speed, the "wrong pattern" and "running pattern" cannot be found in time, which makes the product defective. Product rate increases, production efficiency decreases
