Description
Technical Field
The invention relates to a conveying upper press roller structure, in particular to a conveying upper press roller structure for CTP and an operation method thereof, in particular to a conveying upper press roller structure working perpendicular to a plate feeding direction.
Background
The plate making machine has very high precision requirement on laser scanning, and the laser is naturally needless to say that the accurate positioning of the plate is also of great importance to ensure the high quality completion of the laser scanning process. Traditional CTP generally carries out plate positioning in the vertical direction of plate feeding through a side pull gauge assembly. The side pull gauge assembly is mainly divided into an upper part and a lower part. The lower part is a movable platform which can control the left-right movement of the plate; the upper part comprises a pressing wheel and a limiting piece, the pressing wheel is used for pressing the plate on the lower platform, and the limiting piece is used for providing plate positioning. However, the positioning method has the disadvantage that the position of the pressing wheel is positioned on the edge of the plate, and the plate may be slightly inclined when moving, so that the positioning is not accurate enough, and the error often determines the quality level of the product, thereby influencing the competitiveness in the CTP platemaking machine market.
To solve such problems, it is generally conceivable to add a pinch roller at other positions of the plate, so that a vertical offset is not substantially generated. First, considering the cost, the pinch roller is already independent of the original side-pull gauge assembly, and if the cost is too high, the pinch roller is not as good as the side-pull gauge assembly. It is then considered that the pressure of the press wheel against the plate cannot be great, excessive impact forces tend to leave the press wheel with an impression on the plate, and controlling this force is not easy, because most of the rigid forces generated by common driving means are not tight if the distance is great, and an impression is generated if the distance is small. Therefore, a pinch roller structure should be designed that is inexpensive, compact, and flexible to apply forces to the plate.
