Paperbacked plasterboard edge sealing device

Abstract

An embodiment of the invention discloses a paperbacked plasterboard edge sealing device which is arranged on two sides of a plasterboard. The paperbacked plasterboard edge sealing device comprises a rack, wherein an edge sealing band paper outlet device, a water supply device, a paper folding device, a positioning device and a cut-off device are arranged on the rack; the paper folding device comprises a paper folding board; the positioning device comprises an end part positioning roller, side positioning rollers and a positioning brush, the end part positioning roller is opposite to the end part of the plasterboard, the two side positioning rollers are opposite to two sides of the end part of the plasterboard; the positioning brush is in a U-shaped structure in the side direction and is fixed on the rack through a support frame. One group of edge sealing press rollers are adopted to realize the edge sealing positioning effect, the positioning brush is adopted to apply pressure to stickan edge sealing band on a board, three groups of edge sealing press rollers in the prior art are replaced, pressure of the plasterboard is reduced while a good edge sealing effect is realized, core air holes in the edge sealing position of the end part of the plasterboard are prevented from being damaged by pressing, and the paper taking-off phenomenon is prevented.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of gypsum board manufacture, and in particular to an edge banding device for a paper-faced gypsum board. Background technique [0002] Paper-faced gypsum board is made of building gypsum as raw material, mixed with appropriate amount of additives, fibers and foaming agent diluted several times with water, mixed evenly in a mixer, and then processed with special cardboard for surface protection. [0003] In the production process of gypsum board, the qualified board after drying needs to be trimmed and sealed, and the quality of the sealed side directly affects the quality of the product. At present, the edge banding device used in the gypsum board production line is composed of four sets of nylon pressure rollers acting on the upper and lower surfaces of the gypsum board, and the edge banding is positioned through the guide wheel. After water (glue) is applied, the edge banding is u...

Problems solved by technology

Since the core of the gypsum board is formed by foaming gypsum, the core is distributed with countless uniform pores, and the gypsum board is subjected to the force of the edge-sealing pressure roller during the edge-sealing process, and the air holes of the core at the edge-sealing position of the end of the gypsum board are crushed. , resulting in tearing of the protective paper and the core gypsum and de-papering
