Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 Shown is a guide belt deviation correction device for a rotary screen printing machine, which includes a guide belt 1, a tension roller 2, a drive roller 3, a deviation correction motor, a camera and a controller. The guide belt 1 is stretched between the tension roller 2 and the drive roller 3, and driven by the driving roller 3, the outer surface of the driving roller 3 or the tension roller 2 is provided with a colored coating 4; during normal operation, the colored coating 4 protrudes from both sides of the guide belt 1, and will be colored at this time. The coating 4 protrudes two widths on both sides of the conduction band 1 as the standard width;

[0018] The camera collects the images of both sides of the colored coating 4 protruding from the guide belt 1 in real time, and transmits the images collected in real time to the controller; ...

Abstract

The invention discloses a guide belt correcting device of a rotary screen printing machine. The guide belt correcting device comprises a guide belt, a tension roller, a driving roller, a correcting motor, a camera and a controller. The guide belt is tensioned on the tension roller and the driving roller and transmitted by the driving roller. A coloring coating is arranged on the outer surface of the driving roller or the outer surface of the tension roller. The widths of the portions, protruding out of the two sides of the guide belt, of the coloring coating serve as standard widths in the normal running process. The camera collects images on the portions, protruding out of the two sides of the guide belt, of the coloring coating in real time. The controller obtains widths of the portions, actually protruding out of the two sides of the guide belt, of the coloring coating according to the images collected in real time, determines whether the guide belt deflects or not, and obtains control instructions. The correcting motor corrects the driving roller according to the control instructions. According to the guide belt correcting device of the rotary screen printing machine, by collecting the images on the coloring coating, whether the guide belt deflects or not and which direction the guide belt deflects in can be quite easily determined through comparison, and detection of deflection of the guide belt is quite easy.

Description

technical field [0001] The invention relates to textile technology, in particular to a guiding belt deviation correcting device of a rotary screen printing machine. Background technique [0002] The guide belt (printing guide belt) is a key part of the rotary screen printing machine. The quality of the printing guide belt and whether it is stable during operation are the main factors that determine the printing quality and the life of the guide belt. The printing guide belt requires stable operation, and the control system can automatically correct the deviation of the guide belt. [0003] The existing guide belt deviation correction device realizes deviation correction through the deviation correction roller, the edge detection roller and the micro switch and the deviation correction motor. When the guide belt deviates, the switch control contact of the micro switch on the corresponding side closes, and the deviation correcting motor rotates to make the deviation correctin...
