Device for edge sealing of gypsum plaster board

Abstract

The invention discloses a device for edge sealing of a gypsum plaster board, and belongs to the technical field of mechanical equipment. According to the technical scheme, the gypsum board edge sealing machine is characterized by comprising a rack, an edge sealing belt paper outlet device, a water supply device, a paper folding device, positioning devices and a cutting-off device are arranged on the rack, the paper folding device comprises a paper folding plate, each positioning device comprises an end positioning roller, two side positioning rollers and a positioning brush, and the end positioning rollers are opposite to the ends of gypsum boards; and the two side positioning rollers are opposite to the two sides of the end of the gypsum board, the positioning brush can be seen as an inwards-concave structure in the side direction, the positioning brush is fixed to the rack through a supporting frame, a set of edge sealing pressing rollers are adopted to play a role in edge sealing and positioning, and then the positioning brush is adopted to apply pressure to adhere an edge sealing belt to the board. The pressure on the gypsum board is reduced while a good edge sealing effect isachieved, a board core air hole in the edge sealing position of the end of the gypsum board is prevented from being crushed, and the paper disengaging phenomenon is prevented.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a device for edge sealing of gypsum boards. 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. The edge banding is positioned by the guide wheel, and the edge banding is applied by the nylon pressure rollers after water (glue) is applied. ...

AI Technical Summary

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-paper phenomenon
