Description

Technical Field

[0001] The utility model relates to the technical field of headbox profile adjustment, in particular to a headbox profile adjustment device. Background Art

[0002] The headbox is a critical component of a paper machine, influencing both machine speed and paper quality. Consequently, it's one of the fastest-growing components on modern paper machines and is often called the "heart of the paper machine." As paper machine speeds increase, the time between slurry ejection from the headbox and its finalization on the wire is shortened to a fraction of a second or even a dozenth of a second. Within this short window, the finished paper must maintain a consistent cross-section across the entire width, ensuring a uniform, even sheet. Without a quality headbox, producing high-quality paper is difficult. Key to headbox quality lies in the manufacturing and adjustment of its outlet, upper, and lower lips.

[0003] The existing headbox, such as the prior art with application number CN201821697007.3, includes a feed port, a discharge port, a headbox body, a homogenization assembly, a homogenization rod and a diffuser plate. The homogenization effect on the pulp is improved by increasing the contact area between the homogenization assembly and the pulp. The lifting and repetitive swinging is achieved by a compression spring fixedly connected between the lifting block and the lifting trough, which not only prevents the pulp from flocculating, but also further homogenizes the pulp, thereby improving the homogenization effect.
