Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rock wool composite board processing and production equipment, and particularly relates to a rock wool composite board processing net folding and top slurry system. BACKGROUND

[0002] The four length direction surfaces of the rock wool composite board are wrapped with glass fiber cloth, and the inner and outer two large surfaces are compounded with a polymer cement mortar finishing layer. The rock wool core material is a plate assembled by vertical rock wool strips or a horizontal rock wool plate. Compared with the ordinary rock wool bare plate, the rock wool composite board has the characteristics of high strength, waterproofness, strong adhesion, good labor protection, and the like. In the installation and use, the rock wool composite board is convenient to construct without pollution, can be firmly pasted to the base wall, and solves the problems of water settlement, layered sliding, low tensile strength, and skin damage caused by rock wool fibers of the rock wool bare plate, effectively improves the engineering quality, and can be widely applied to wall insulation engineering of various building structures. In the production and processing process of the rock wool composite board, the glass fiber cloth needs to be installed on the four length direction surfaces of the rock wool core material, and the polymer cement mortar finishing layer needs to be coated on the inner and outer two large surfaces. At present, the rock wool composite board is usually produced manually. The rock wool plate needs to be cut into the designed size, the glass fiber cloth is manually wrapped on the four length direction surfaces of the assembled rock wool core material, and then the polymer cement mortar finishing layer is manually coated on the inner and outer two large surfaces. This operation mode has low efficiency, poor product consistency, and high labor cost. In the rock wool composite board production line, the quality of the glass fiber cloth wrapping directly affects the quality of the product, so manual wrapping of the glass fiber cloth is usually adopted in the production line, which affects the operation efficiency of the production line and increases the labor cost. In the existing rock wool composite board production line, the glass fiber cloth is laid on the conveying belt, a layer of polymer cement mortar finishing layer is laid on the glass fiber cloth, and then the rock wool core material is laid on the polymer cement mortar finishing layer. A mechanical device is used to automatically wrap the glass fiber cloth, and then a pressing mechanism is used for pressing to improve the adhesion and tightness of the polymer cement mortar finishing layer and the rock wool core material. However, in the actual operation process, the tightness of the glass fiber cloth wrapping cannot be guaranteed by only using the natural folding method, and a large amount of defective products or waste products are generated. After the glass fiber cloth wrapping is completed, the top slurry operation is also needed. In the conventional case, a hopper is arranged on the conveying belt of the production line, a gap is arranged between the bottom of the hopper and the rock wool core material, and the polymer cement mortar is overflowed from the gap to form the polymer cement mortar finishing layer. However, in the actual operation process, the polymer cement mortar finishing layer formed by this method is loose, the adhesion effect of the polymer cement mortar finishing layer and the rock wool core material is poor, and the rock wool core material and the polymer cement mortar finishing layer are easy to separate after drying, so the defective product rate or the waste product rate is high. SUMMARY
