Plate feeding device of nanometer material computer to plate and control method for plate feeding device

Abstract

The invention relates to a plate feeding device of a nanometer material computer to plate and a control method for the plate feeding device. A driving motor of a first roller in the device is used for receiving a control signal to drive a material plate to enter the plate feeding device; a positioning device is used for positioning the material plate in the axial direction of a drum; a control unit is used for receiving a position feedback signal of the driving motor of the first roller and outputting the control signal to a control loop of a head clip cylinder; and the control unit is used for outputting the control signal to a control loop of a tail clip cylinder according to a position signal fed back by a printing unit. The method comprises the following steps of: starting the drum to rotate to an original point and starting a pneumatic unit; starting the first roller to roll the material plate and positioning the material plate at a first detection position; when the material plate reaches a second detection position, sending a rotation position signal of the first roller to the control unit; when the material plate reaches a head clip position, turning off a head clip; and when the material plate reaches a tail clip position, turning off a tail clip to end a plate feeding process. According to the plate feeding device of the nanometer material computer to plate, the material plate can be totally rolled onto the drum, so that a printing face is solid and smooth, positioning is accurate, and the operating accuracy and the control precision of the whole nanometer material computer to plate are ensured.

Description

technical field [0001] The invention relates to a plate-loading device in plate-making technology, in particular to a plate-loading device of a nano-material direct plate-making machine and a control method thereof. Background technique [0002] The printing industry is an industry that has an important impact on my country's national economy. Plate-making and printing technology has a history of more than 2,000 years in my country, and embossed block printing and movable type printing were the first to be used. At the beginning of last century, laser technology was invented, and then laser plate-making technology was derived. At present, the laser phototypesetting technology is dominant in my country's printing industry. This technology is considered to be the second revolution of my country's printing technology after Bi Sheng's invention of movable type printing. It makes my country's printing industry "say goodbye to lead and fire, Welcome light and electricity." [00...

AI Technical Summary

Problems solved by technology

In the plate-loading process of the drum-type plate-making machine in the prior art, the positioning accuracy of the material plate is not enough, the printing quality cannot be guaranteed, and the direct printing requirement of the short distance from the print head to the printing surface of the material plate cannot be met. Therefore, an applicable Plate-loading device and control method of nano-material direct plate-making machine for new plate-making process

Above-mentioned device and method have not been reported at present
