Drum core bend preventing device of barrel fluffer

Abstract

The invention discloses an anti-bending device with drum core of cylinder untwining machine, comprising drum core set in the cylinder of untwining machine along the axial direction of cylinder of untwining machine. At two ends of the drum core two supports of drum core are fixed respectively and straightening device for drum core, which makes the axial line of drum core straight, is set between two supports of drum core. The axial line of the straightening device for the drum core is located under the axial line of said drum core. By adjusting the straightening device of drum core, the flatness of drum core in cylinder can be adjusted to guarantee the reasonable gap between the drum core and the cylinder and improve the assembling efficiency of the whole machine and the working reliability.

Description

technical field [0001] The invention relates to a drum deflaker in the technical field of papermaking machinery and papermaking machinery, in particular to a drum core of the drum deflaker. Background technique [0002] The advantage of the drum deflaker is that it decomposes waste paper fibers without shredding waste and producing fine fibers, without consuming unnecessary stirring, cutting fibers and impurities, and lower energy consumption; its cylinder 1 includes The pulping area and the screening area, the working principle of the pulping area is shown in Figure 3. The waste paper entering the pulping area is soaked by water and chemicals. Since the cylinder 1 is slightly inclined, the waste paper slowly flows to the pulping area by gravity. It moves forward, while the partition on the inner wall of the cylinder continuously picks up the waste paper and drops it to the bottom of the cylinder at a certain height, and uses the shearing force to loosen the waste paper fibe...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure that the waste paper clusters fall from the height of the cylinder 1 as much as possible to generate the maximum kinetic energy for defoliation, a drum core 2 is installed in the cylinder of the cylinder defibrillator. Next, the waste paper ball is picked up by the partition and moves to the top of the cylinder. During this process, the partition and the "D" shaped drum core move relatively, and when the waste paper ball turns over the top of the drum, it depends on gravity and inertia. , the waste paper balls fall down from the vertical side of the "D" shaped drum core 2, and when they fall to the bottom, the decomposing teeth of the partition at the bottom will decompose the waste paper again, so that the decomposing ability is greatly improved; but the structure of this structure The disadvantage is: the drum core is long, and the drum core installed in the cylinder will produce downward bending, which will affect the movement of waste paper, and the bending will continue to increase, which will eventually cause damage to the entire equipment
