Description

Technical Field

[0001] The invention relates to the field of gypsum board production, and in particular to a gypsum board conveying device. Background Art

[0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, good sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. It is usually used for the decoration of indoor walls and ceilings. It is made of materials such as gypsum and cellulose, and has the advantages of lightness, fire resistance, water resistance, and heat insulation, so it is widely used in the field of building decoration. In addition to conventional gypsum boards, there are also some special gypsum boards, such as moisture-proof gypsum boards, fire-resistant gypsum boards, water-resistant gypsum boards, etc., which can be selected according to different needs. In general, gypsum board is a very practical building material that can provide good effects and guarantees for interior decoration.

[0003] When producing gypsum board, gypsum, cellulose and other raw materials are first mixed in a certain proportion to make the main material of the gypsum board, and then the mixed raw materials are put into a mixer to mix them evenly. After being stirred, the gypsum slurry flows from the mixer to the upper and lower layers of the face paper, and is extruded and formed by the board forming machine. The formed gypsum board is cut into suitable sizes after passing through the conveyor roller, and placed in the drying room for drying to achieve a certain hardness and stability. Cut and seal the edges as needed, and package the cut gypsum board for transportation and use.

[0004] Patent application number: CN202310736719.0 discloses a gypsum board conveying system, which discloses a deviation correction mechanism, which includes a slide, a slider and a push head. The side wall of the first bracket is symmetrically fixed with a mounting seat, the slide is fixedly installed on the upper part of the mounting seat, the slider is slidably installed in the inner cavity of the slide, the push head is rotatably installed at one end of the slider, a telescopic cylinder is fixedly installed on the upper part of the slide, the telescopic end of the telescopic cylinder is rotatably connected to the push head, a number of pulleys are rotatably installed on the side wall of the push head, a damping rod is symmetrically fixedly installed in the inner cavity of the slide, and one end of the damping rod abuts against the slider. When the gypsum board is corrected, the cylinder pushes the gypsum board to move on the conveyor belt to achieve the straightening of the gypsum board, but when the gypsum board is pushed to move, the conveyor belt and the gypsum board ground rub against each other, which can easily scratch the gypsum board.
