Sizing roller with self-cleaning function and using method thereof

Abstract

The invention discloses a sizing roller with a self-cleaning function and a using method thereof, and relates to the technical field of sizing rollers. The sizing roller aims to solve the problem that an existing sizing roller is inconvenient to clean after being used. Outer rollers are arranged between sizing frames, rotating shafts are fixedly arranged at the two ends of each outer roller, a sizing net cylinder is fixedly arranged between the outer rollers, an inner roller is arranged in the sizing net cylinder, the outer wall of the inner roller is attached to the inner wall of the sizing net cylinder, a liquid conveying main pipe is arranged in the middle of the interior of the inner roller, a plurality of sets of liquid conveying branch pipes are annularly and evenly arranged outside the liquid conveying main pipe, the liquid conveying branch pipes and the liquid conveying main pipe are fixed in a sealed mode, anti-blocking mechanisms are arranged at the ends, close to the sizing net cylinder, of the liquid conveying branch pipes, a mounting shaft is fixedly arranged on one side of the inner roller, the mounting shaft is rotationally connected with the rotating shafts and the sizing frames through bearings, a fan-shaped cover is fixedly arranged at the upper end of the sizing frames, and a scraping mechanism is installed in the fan-shaped cover.

Description

technical field

[0001] The invention relates to the technical field of sizing rollers, in particular to a sizing roller with self-cleaning function and a use method thereof. Background technique

[0002] The sizing machine is divided into two types: horizontal and inclined, pneumatically pressurized, and the purpose of surface sizing is usually to prevent liquid penetration, obtain better surface properties and improve the physical properties of the paper (such as surface strength and internal bonding force) ), is an effective means to improve the performance of the base paper. The sizing roller is an important part of the sizing machine, which continuously, uniformly and stably coats the emulsified glue on the surface of the paper. Physical action forms an extremely thin waterproof layer on the surface of the paper, which greatly improves the water absorption of the paper, and at the same time increases the bonding strength between the fibers and the tightness of the paper ...
