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 is provided with a colored coating 4 equal to the width of the guide belt 1; during normal operation, the guide belt 1 completely covers the colored coating 4;

[0018] The camera collects the images of both sides of the guide belt 1 on the driving roller 3 in real time, and transmits the images collected in real time to the controller;

[0019] The controller obtains whether the colored coating 4 protrudes from the guide belt 1 according to the images collected in real time, ...

Abstract

The invention discloses a guiding belt deviation rectifying device of a circular screen printer. The guiding belt deviation rectifying device comprises a guiding belt, a tension roller, a driving roller, a deviation rectifying motor, a camera and a controller. The guiding belt is arranged on the tension roller and the driving roller in a tensioning mode and carries out transmission through the driving roller. A coloring coating layer with the same width as the guiding belt is arranged on the outer surface of the driving roller. During normal operation, the guiding belt completes covers the color coating layer. The camera collects images of the two side ends of the guiding belt on the driving roller in real time. The controller determines whether the coloring coating layer protrudes out of the guiding belt according to the images collected in real time, whether the guiding belt deviates is determined, a control order is obtained, and the control order is sent to the deviation rectifying motor. The deviation rectifying motor carries out deviation rectifying on the driving roller according to the control order. According to the guiding belt deviation rectifying device of the circular screen printer, the images of the coloring coating layer are collected, whether the guiding belt deviates can be easily know by comparing, the direction of deviating can be easily known by comparing, and detecting of guiding belt deviation is very 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...
