A coating machine shaping device

Abstract

The utility model provides a coating machine shaping device. When stone paper with bidirectional ruffles passes through the first shaping roller of the shaping device, the calendering part of the first calendering roller used for shaping is pressed on the stone paper to be shaped on the first shaping roller, playing the original tension effect and shaping effect. The ruffle area avoidance part avoids the ruffle area of ​​the stone paper to be shaped on the first shaping roller, so that the bidirectional ruffles will not be squeezed when passing through, avoiding the generation of edge dead marks. At the same time, no bubbles will be generated when passing through the coating head, avoiding the generation of missed coating points, thereby reducing the loss rate and improving the paper roll utilization rate and yield rate.

During coating, the calendering wheel device after unwinding will cause two-way dead marks. When passing through the coating head, it will cause edge dead marks, perforations, and fine dead marks, resulting in serious quality defects.

[0030] Based on this, the utility model provides a coating machine shaping device, which includes a bracket 10, a plurality of shaping rollers, a first calendering roller 30 and a first driving device 40. Among them, a plurality of shaping rollers are arranged on the bracket 10, and the axes of adjacent shaping rollers are staggered with each other, and the stone paper to be shaped passes around each shaping roller in turn. The first calendering roller 30 is arranged on one side of the first shaping roller 21 among the plurality of shaping rollers, and the first calendering roller 30 includes a calendering portion 31 located in the middle and a lotus leaf area avoidance portion 32 located at both ends of the calendering portion 31, and the outer diameter of the lotus leaf area avoidance portion 32 is smaller than the outer diameter of the calendering portion 31. The first driving device 40 is arranged on the bracket 10, and is used to drive the first calendering roller 30 to move between a first working position and a first avoidance position. In the first working position, the calendering part 31 presses on the stone paper to be shaped on the first shaping roller 21, and the lotus leaf area avoidance part 32 avoids the lotus leaf area of ​​the stone paper to be shaped on the first shaping roller 21. In the first avoidance position, the first calendering roller 30 avoids the stone paper to be shaped on the first shaping roller 21.

[0031] In the coating machine shaping device provided in this embodiment, when the stone paper with bidirectional ruffles passes through the first shaping roller 21 of the shaping device, the calendering part 31 of the first calendering roller 30 used for shaping is pressed on the stone paper to be shaped on the first shaping roller 21, playing the original tension and shaping role, and the ruffle area avoidance part 32 avoids the ruffle area of ​​the stone paper to be shaped on the first shaping roller 21, so that the bidirectional ruffles will not be squeezed when passing through, avoiding the formation of edge dead marks.
