Description

Paper receiving alarm device for paper frame at same speed and control circuit thereof

Technical Field

The utility model relates to a lithography apparatus technical field especially relates to a with fast paper frame paper splicing alarm device and control circuit thereof.

Background

A printer is a machine that prints text and images. Modern printing presses typically consist of plate loading, inking, stamping, paper feeding (including folding) and the like. The working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred on the paper or other printing material (such as textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to reproduce the same printed matter as the printing plate.

In the existing printing machine, which is usually a roll-to-roll printing machine, the to-be-printed matter enters the printing machine in the form of a roll material and is unwound, and printing is completed. After a roll coil stock printing was accomplished, need change the coil stock, in order to ensure the efficiency of printing production, do not shut down or the short time is shut down under the normal conditions, decide old coil stock, in the middle of new coil stock direct access printing machine, this process is called the paper splicing for short. The existing printing machine is provided with a paper roll thickness detection device in the middle of the printing machine or the paper receiving machine in order to remind an operator to carry out paper receiving operation, and when the thickness of a paper roll in printing is smaller than a preset value, an alarm is sent out to remind the operator to carry out paper receiving. However, in this method, there is still 3-5 minutes from the actual cutting and splicing of the old roll, and personnel still need to manually observe when the new roll is cut and spliced, sometimes the joint during the paper changing cannot be found in time during the high-speed operation and switching of the two rolls, and the overprint and ink color change caused by the paper changing cannot be adjusted in time (generally, the adjustment requires 3-5 paper consumptions). Especially in the case of inattention after the late night when the person is exhausted. The increase of waste products and even product quality accidents are easily caused.
