Cycloid silk feeding device for glass fiber gypsum board production line

Abstract

The invention discloses a cycloid silk feeding device for a glass fiber gypsum board production line and relates to glass fiber gypsum board production equipment. By using the device, a glass fiber tow can be kept synchronously running with the gypsum board production line; adding of glass fiber tows in different states is achieved by adjusting speed so that production of gypsum boards in different strength and function requirements can be achieved; glass fiber yarn coils are vertically installed, the coil diameter is small, but the tow reaches a length of thousands of kilometers, is in multi-station alternate use, and can be conveniently subjected to position interchanging, and yarn coil replacing is convenient; after jetting and blowing, the tow can be scattered into single silks, and the state of the single silks is adjustable according to the air speed; a silk feeding flat nozzle can swing up and down in terms of position or performs singular direction silk feeding, so that different production requirements can be met; silks for use are saved, the silk feeding speed and the silk feeding angle positions are adjusted according to the strength requirement, for example, straight line, curved line or superimposed curved line silk feeding is performed, so that glass fiber grids in different states can be formed and added into gypsum board material slurry, the production cost is reduced, the product quality is improved, and the cycloid silk feeding device for the glass fiber gypsum board production line is suitable for high speed production of a gypsum board large line with v equal to 60-120 m / min.

Description

Technical field [0001] The invention relates to a production equipment of glass fiber gypsum board, in particular to a cycloid wire feeding device for a glass fiber gypsum board production line. Background technique [0002] Due to the high-speed and efficient production requirements of the gypsum board production line, the continuous production speed of modern large-scale gypsum board lines is usually higher than 60m / min. The national industrial policy also sets the line speed 60m / min as the benchmark for the elimination of gypsum board production lines. Due to the increasing molding speed The gypsum board face protection paper has been developed in a light and thin direction under the premise of maintaining a constant strength. The weight of the face protection paper is generally less than 210g / ㎡. The roll diameter of the gypsum board face protection paper is getting larger and larger. The continuous length of tissue paper generally reaches 8000m or even more than 10,000 meters...

AI Technical Summary

Problems solved by technology

[0003] Fiberglass gypsum boards usually use special devices to add chopped glass fibers to improve the uniform distribution of chopped glass fibers inside the gypsum board core to improve bending strength and fire performance, but to some extent chopped glass fibers are not Regular distribution state, no significant increase in strength

Adding glass fiber mesh cloth can form composite mesh ribs in a layered manner, but the diameter of the glass fiber mesh cloth is small, and the continuous length of a single roll of glass mesh cloth is only 100-200 meters. The single-roll glass mesh with special measures The longest continuous length of grid cloth is less than 1500 meters, so it is only suitable for small-scale gypsum board production lines. The continuous production speed is usually υ≯10m / min, and the highest speed does not exceed 20m / min. Due to the addition of glass mesh cloth, only Able to run at reduced speed or maintain low rate continuous production at slow speeds

Due to the frequent replacement of rolls, it can only be added at a slow production speed, which makes it difficult to achieve continuous production for high-speed gypsum board lines, especially in the operating state of υ﹥30m / min, the glass fiber mesh will be due to It is not coordinated with the synchronization of the lower paper and is stretched and distorted into irregular rectangular grids, irregular rhombus grids and other shapes, resulting in uncontrollable and stable addition, affecting continuous production, and not suitable for large-scale high-speed gypsum of 60-120m / min Board line production, and the need to improve the quality of gypsum board products

Common problems faced by the existing technology: 1. Glass fiber mesh cloth is packed in flat, usually two rolls are used alternately; 2. Glass fiber mesh cloth roll diameter is small

Each roll is only 100-200 meters, or even less than 1500m, and the rolls are replaced frequently; 3. It can only run synchronously; 4. The glass fiber mesh is drawn into a twisted and irregular rectangle; 5. It is only suitable for υ≯20m / min gypsum boards Line low-speed production;

[0004] In order to improve the bending and flexural strength of the paper-faced gypsum board, to improve its fire prevention and support functions, to meet the decoration needs of places with a large public flow of people, especially shopping malls, stadiums, stations and other places, to achieve higher anti-collision and impact resistance performance, usually by adding crushed glass filaments, chopped glass fibers, and glass fiber grid cloth to obtain a high dispersion rate of glass fibers inside the gypsum board core as much as possible, but in practice, due to the addition of equipment, continuous production, and fixed-length Cut off, high production line speed, frequent replacement and other reasons are greatly restricted
