Problems solved by technology
[0002] Due to the large width of the large paper machine and the large paper roll of the coating machine, it is difficult to control the flatness of the whole width, which is the main bottleneck of the current quality problem, which seriously restricts the improvement of quality
[0003] Specifically, during the processing of large paper rolls, the thicker parts of the paper rolls accumulate at the same position and tend to have obvious swollen ridges, which affects the flatness of large paper rolls
Moreover, the swollen ridges on the roll paper will cause paper surface wrinkles in the subsequent processing and printing process, and it is difficult to meet the customer's requirements for a smooth paper surface.

The invention discloses an evenness processing device for a scroll and a calender and a rewinder. The processing device comprises a substrate and a driving part, wherein the scroll is mounted on the substrate; and the driving part drives the substrate to drive the scroll to move in a reciprocating manner along an axial direction parallel to the scroll. By means of the device, high and low points of the scroll can be adjusted in a staggered manner, so that the evenness of the scroll is improved.
Description
technical field [0001] The invention relates to the field of papermaking, in particular to a paper roll flatness processing device, a calender, and a rewinding machine. Background technique [0002] Due to the large width of the large paper machine and the large paper roll of the coating machine, it is difficult to control the flatness of the whole width, which is the main bottleneck of the current quality problem, which seriously restricts the improvement of quality. [0003] Specifically, during the processing of large paper rolls, the thicker parts of the roll paper are prone to obvious swollen ridges at the same position, which affects the flatness of the large paper roll. Moreover, the swollen ridges on the roll paper will cause paper surface wrinkles in the subsequent processing and printing process, and it is difficult to meet the customer's requirements for a smooth paper surface. Contents of the invention [0004] The technical problem mainly solved by this appli...
