Extrusion equipment for plasterboard

Abstract

The invention discloses a paper surface gypsum board extrusion equipment, which includes a base, a special-shaped marking unit and a secondary extrusion unit; the base: the four corners of the lower side are fixed with legs, and the upper side is fixed with a third support frame. The left lower end of the third support frame is provided with an indicating hole, the upper side of the third support frame is arranged in a linear array with first electric push rods, and the output end of the first electric push rods passes through the third support frame A first moving frame is fixed, and a squeeze roller rotates through a rotating shaft in the lower end of the first moving frame. This paper-faced gypsum board extrusion equipment can first wrap the paper and squeeze the gypsum slurry, and then detect the gypsum board after wrapping, and mark the detected unevenness, so that the staff can quickly find defects After the paper wraps the slurry, the finished product can be squeezed left and right to ensure the flatness of the surface of the gypsum board, avoid wrinkles, etc., and improve the quality of the gypsum board.

Description

technical field [0001] The invention relates to the technical field of production equipment for gypsum boards, in particular to extrusion equipment for gypsum boards. Background technique [0002] Paper-faced gypsum board is a board made of building gypsum as the main raw material, mixed with appropriate amount of additives and fibers as the board core, and made of special cardboard as the surface protection. Paper-faced gypsum board has the characteristics of good toughness, non-combustibility, stable size, smooth surface, can be sawed, and is convenient for construction. It is widely used in suspended ceilings, partition walls, interior wall veneers, ceilings, sound-absorbing panels, etc. Paper-faced gypsum board The production process is as follows: After the upper paper is unrolled, it enters the extrusion molding machine through the automatic deviation correcting machine; The lower paper enters the extrusion molding machine, and the gypsum board of the required specifi...

Paper-faced gypsum board has the characteristics of good toughness, non-combustibility, stable size, smooth surface, can be sawed, and is convenient for construction. It is widely used in suspended ceilings, partition walls, interior wall veneers, ceilings, sound-absorbing panels, etc. Paper-faced gypsum board The production process is as follows: After the upper paper is unrolled, it enters the extrusion molding machine through the automatic deviation correcting machine; The lower paper enters the extrusion molding machine, and the gypsum board of the required specification is extruded on the molding machine, and then the initial setting is completed on the solidification belt, and the final setting is completed on the conveying roller table, and cut into the required length (2400mm) by the fixed-length cutting machine , 3000mm or other), and then enter the next step; and the existing gypsum board slurry will be mixed with air bubbles, and the internal air bubbles cannot be well discharged during extrusion molding, which may cause molding. There are air bubbles inside the gypsum board, so that when the two layers of paper wrap the gypsum board, there will be unevenness. In this case, the defective products are not easy to detect. In the production of gypsum board, the gypsum board is generally cleaned before wrapping. The slurry shakes up and down, but if there are still unevenness or wrinkles after the paper wraps the slurry, it is not convenient to carry out secondary repairs on the gypsum board
