Abstract

The invention discloses a kind of folder meshwork vacuum roller former for high speed tissue paper machine. The former realizes two-sided dehydration depending on mental efforts and vacuum suction procreated by high speed circumvolving of vacuum roller. Thanks to fixing pressure pulse extruding device on meshwork of formation arc zone, brace procreated by the meshwork can also make slurry dewater vastly. The former is characterized in that the dewatering zone is divided into three areas including centrifugal, vacuum and centrifugal pressure dehydration, which realizes step dewatering and efficient forming. The former including guide roll, vacuum forming roll, outer-mesh, inner-mesh, flexible pressure pulse extruding device on meshwork, air compartment etc. It makes slurry to dewater and form efficiently without agitating. Because of the balanced property of two-sided dewatering nature, sheet uniformity and two-side compatibility are good. With simple structure, low drive power and good reliability, the former is applicable on tissue paper machine with high speed and low range.

Description

technical field [0001] The invention relates to a pulp former, in particular to a gap vacuum roller former for a high-speed tissue machine. Background technique [0002] Due to the rapid development of the world economy in recent decades, the usage of household paper and paper products has also increased rapidly. Household paper and paper products have become a fast-growing variety in the paper industry, and its development has promoted the accelerated renewal and replacement of toilet paper machines. At present, the advanced tissue paper machine has reached a width of 6m and a speed of 2400m / min. In order to obtain higher economic benefits, the current modern high-speed tissue paper machine usually adopts a multi-layer floating machine based on the uniform distribution of high-turbulent pulp as its basic function. Sheet-type stepped diffusion headbox, the application of layering technology on the headbox of high-speed tissue paper machine requires...
