There are several thicknesses of printing paper

During normal printing of the machine, the paper feed head, front gauge, pull gauge, paper feed system, and front gauge survey system cooperate closely, but in view of the cause of the paper or the mediation problem, several or even a dozen papers come in the impression cylinder and rubber cylinder. The parking becomes abrupt, which is called stuffy car.The stuffy car becomes a fatal influence on the edge of the printing machine, so it is necessary to make the printing workers value.

The main causes of boring cars are: First, the gap is not well adjusted, including between the paper feed head and the paper feed platen, between the paper feed rollers and paper feed rollers of the machine's double-sheet manipulator. The height adjustment is not suitable. Usually, the thickness is 3 sheets of printing paper. Or the ultrasonic double-sheet manipulator and the pendulum tissue malfunction, and it becomes double sheets. Second, the paper adhesion causes several sheets to be sucked and output at the same time. The reason is that the ink layer of the printed product is too thick or the paper is deformed. Third, it is a stuffy car incident. When the printing press is in normal occupation, if the front of the paper arrives early, late, tilted, missing corners, curling, lack of paper, the photoelectric survey is immediate. The front rule is ordered to stop swinging to prevent the paper from entering the roller again. At the same time, the swinging delivery tooth does not hold the paper, the machine is delayed, the roller is depressurized, the platen roller is lifted, the water transfer roller, and the ink roller are stopped swinging. Failure of the control line is as simple as rolling a stack of paper between the impression cylinder and the rubber cylinder, and the car accident will occur.
