Our company's printing machine mainly based on thick paper (quantity is 250 ～ 350g / m2), when printing thin paper with large folio and basis weight of 40g / m2 at one time, the paper is in the delivery row and impression cylinder During the handover of the gripper row, there was a drop of paper, and the gripper of the paper was slightly bent. Why didn't this problem occur when printing thick paper, but when printing thin paper?

For this problem, the author first used a thick paper to pick the car and move the paper, carefully observing the handover process of the paper between the delivery tooth row and the impression roller gripper row. When the paper delivery row passes the paper to the impression cylinder gripper row, the author adopts the method of positive and negative clicks to make the paper repeat back and forth between the delivery row and the impression cylinder gripper row for two-way handover At this time, there is no paper drop. The author used another piece of thin paper with a basis weight of 40g / m2 to perform the same test, and the problem occurred: when the paper delivery row was passed to the impression cylinder gripper row, the gripper gripper teeth of the impression cylinder Before the paper is completely gripped, the grippers of the hand row are loosened and the paper falls. Until the car hits 3 to 4 degrees, the impression cylinder gripper row is completely closed.
As we all know, when paper is transferred between the impression cylinder and the delivery row, the gripper row and delivery row of the impression cylinder must grip the paper in the same straight line at the same time so that the paper does not fall. Judging from the author's inspection results, these two parts of the printing machine obviously do not meet this condition. This problem does not occur when printing thick paper, because thick paper is thicker, and its hardness and toughness are better than thin paper, so during the handover process, even if the impression roller gripper row is not fully closed, it can be It won't drop if you hold it; but when printing thin paper with the same printing machine, the problem of falling paper cannot be avoided.
Therefore, the author adjusted the opening time of the gripper row of the impression cylinder to make it correspond to the handover time of the delivery row. Click the car to go and observe the paper, the paper no longer drops.
