A kind of edge banding device for gypsum board

Abstract

The embodiment of the present invention discloses an edge sealing device for gypsum board, which is arranged on both sides of the gypsum board. Water supply device, origami device, positioning device and cutting device, the origami device includes origami board, the positioning device includes an end positioning roller, a side positioning roller and a positioning brush, the end positioning roller and the end of the gypsum board The two side positioning rollers are opposite to each other, and the two side positioning rollers are opposite to the two sides of the end of the gypsum board. The positioning brush is fixed on the frame through the support frame, and a set of edge-sealing pressing rollers are used to position the edge-sealing, and then the positioning brush is used to press the edge-sealing tape to stick the edge-sealing tape on the plate, instead of the conventional method. Three sets of edge-sealing rollers can reduce the pressure on the gypsum board while achieving a good edge-sealing effect, avoid the core air holes at the edge-sealing position at the end of the gypsum board from being crushed, and prevent paper stripping.

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
