Ink jet printing machine with guiding belt transmission error compensation function

Abstract

The invention discloses an ink jet printing machine with the guiding belt transmission error compensation function, and belongs to the field of ink jet printing equipment. An ink jet printing machinein the prior art cannot measure moving errors accurately and thus automatic and accurate ink jet printing cannot be achieved. According to the ink jet printing machine, a driving system drives an object to be printed to move automatically, manpower can be effectively saved and ink jet efficiency is improved; and meanwhile compared with manual regulation, more accuracy can be achieved. By means ofthe ink jet printing machine, no light source detection (sensing) equipment and camera shooting equipment need to be arranged, invested cost is low, the structure is compact, the moving errors can beobtained at once, no repeated measurement and image contrast are required, and the working efficiency is high. A position correction mechanism is arranged, an ink jet printing head device can be automatically adjusted to move accurately according to the moving errors of the object to be printed, the moving errors are accurately compensated for, and the scheme is detailed and practicable. The ink jet printing head device can be adjusted automatically through a mechanical structure, manpower can be effectively saved, and the ink jet efficiency is improved; and meanwhile compared with manual regulation, more accuracy can be achieved.

Description

technical field [0001] The invention relates to an inkjet printing machine with transmission error compensation of a guide belt, belonging to the field of inkjet printing equipment. Background technique [0002] The belt-guiding inkjet printing machine of the prior art includes an inkjet printing head device, a drive system, and a control unit. The inkjet print head device is composed of several identical inkjet units, and the material to be printed is driven by the drive system. Step by step, the control unit controls the inkjet unit corresponding to the inkjet print head device to spray ink on the material to be printed to complete the printing. The drive system includes a stepping motor, a roller connected to the rotating shaft of the stepping motor and a conveyor belt for placing the material to be printed, and the roller drives the conveyor belt to move. Due to the processing error of the cylinder, the assembly error of the cylinder and the conveyor belt and other reas...

AI Technical Summary

Problems solved by technology

Since each movement will produce a certain error, this technical solution uses the movement error of the previous station for the movement control of the next station, the control accuracy is not high, and the actual error is relatively large, which affects the printing accuracy and printing accuracy
