Cylinder molding part sandwiched sizing system device

Abstract

The invention relates to a cylinder molding part sandwiched sizing system device. The device comprises a dissolution tank and a sizing tank which is arranged under and communicated with the dissolution tank, wherein the sizing tank is connected with a sizing pump, a glue delivery pipe and a sprayer; the sprayer is mounted at No.1 molding cylinder molding paper sheet and dragged in a crack part between the No.2 and No.3 molding cylinders by coarse cotton cloth. The cylinder molding part sandwiched sizing system device can be utilized for the multi-cylinder molding parts to strengthen the binding force between the multi-cylinder paper sheets, and improve the sizing amount according to the physical index and requirements. The product quality of a paper machine without the sizing machine can be improved by cylinder molding part sandwiched sizing, and the equipment cost investment can be further reduced, so that the purposes of saving energy, reducing consumption, reducing cost and increasing efficiency can be achieved.

Description

technical field [0001] The invention belongs to the technical field of papermaking machinery, and in particular relates to a sandwich glue sizing system device of a cylinder part. Background technique [0002] In the process of producing corrugated paper and containerboard in the rotary paper machine, the physical indicators such as delamination, low ring crush strength, and folding resistance cannot compete with the quality of the fourdrinier and stacked paper machines, resulting in the production of rotary paper machines. The products are unsalable, paper prices are falling, and even falling into the predicament of facing production stoppage without orders. The main reason is that there is no sizing equipment in the rotary paper machine, and the sizing operation for corrugated paper and cardboard paper cannot be performed, so the paper sheets are delaminated, have low ring crush strength, and are not resistant to folding. Contents of the invention [0003] The object of...

[0002] In the process of producing corrugated paper and containerboard in the rotary paper machine, the physical indicators such as delamination, low ring crush strength, and folding resistance cannot compete with the quality of the fourdrinier and stacked paper machines, resulting in the production of rotary paper machines. The products are unsalable, the paper price is low, and even in the predicament of facing production stoppage without orders

The main reason is that there is no sizing equipment in the rotary paper machine, and the sizing operation for corrugated paper and cardboard paper cannot be performed, so the paper sheets are delaminated, the ring compression strength is low, and they are not resistant to folding.
