A kind of automatic fire-stop ring core material production equipment and method

Abstract

The invention discloses automatic firestop collar core material production equipment. The automatic firestop collar core material production equipment comprises a conveying device, wherein a core material molding machine and a packaging table are arranged above the conveying device; and a dryer, a cooler and a cooling curer are arranged between the core material molding machine and the packaging table in sequence. A method for producing firestop collar core materials by using the equipment comprises a stirring and mixing procedure, a core material die-casting molding procedure, a core material blank drying procedure, a core material blank cooling procedure and a core material blank low-temperature curing procedure. The production equipment and method are skilful in design, and improve the production efficiency and the product quality of the firestop collar core materials.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to an automatic fire-stop ring core material production equipment and method. Background technique [0002] Due to the superior corrosion resistance of plastics, hard polyvinyl chloride pipes have been widely used in the construction industry to replace traditional metal pipes as drainage pipes. It also has the advantages of low price, convenient construction, long service life, etc., but it has a fatal disadvantage, that is, it is easy to melt, and once a fire occurs, the fire is easy to spread along the rigid PVC pipe, posing a great safety hazard. For this reason, people design a kind of fire arresting ring. The fire retardant ring is made of a metal shell and filled with a flame retardant expansion core material. It is set on the outer wall of the hard PVC pipe and fixed on the floor or wall. When a fire occurs, the core material expands rapidly and squeezes The heat-softe...

Problems solved by technology

[0003] After the core material of the fire retardant ring is initially formed, it needs to be dried and cured. However, in the existing production process of the fire retardant ring, in the drying and curing stage of the core material, the drying and curing are achieved by natural air drying. It takes 2-3 days to solidify and form under weather conditions, and it will take longer to dry and solidify in rainy weather, which seriously affects production efficiency and product quality, and needs to be improved
