Extrusion molding device of glass-magnesium board material

Abstract

The invention discloses an extrusion molding device of a glass-magnesium board material, and the extrusion molding device is used for a glass-magnesium board material production line in a construction decorative material industry. The extrusion molding device comprises an upper extrusion roller and a lower extrusion roller which are arranged inside a mounting bracket and the mounting bracket is fixedly equipped with two pairs of parallel guide rails; the upper extrusion roller is supported in a belt bearing slide block seat which can slide in the parallel guide rails; material pressing screw rods are supported in a mounting plate through a bearing and the lower ends of the material pressing screw rods are connected with the belt bearing slide block seat through screw threads; the upper end of each material pressing screw rod is in meshing drive with a worm rod on a driving shaft through a worm wheel and one end of the driving shaft is connected with a driving device; and the upper extrusion roller and the lower extrusion roller are respectively driven by a power transmission device. The extrusion molding device provided by the invention has the advantages that the distance betweenthe upper extrusion roller and the lower extrusion roller can be adjusted more conveniently and more simply, the process is more stable and the adjusting precision is higher. The extrusion molding device of the glass-magnesium board material can be widely applied to the glass-magnesium board production line.

Description

technical field [0001] The invention relates to production equipment of glass magnesium boards in the building decoration material industry, in particular to an extrusion molding device used on a glass magnesium board production line. Background technique [0002] The glass magnesium industry is a new industry in China, which started relatively late, but has developed rapidly in recent years. Glass magnesium material is an emerging building material in recent years. It has become an indisputable fact that glass magnesium replaces wood, glass magnesium instead of steel, and glass magnesium instead of cement in some projects. In terms of cost, molding, operation, performance, etc., glass magnesium Materials play their unique advantages. At present, glass magnesium products such as fireproof boards, ventilation ducts, lightweight partition walls, logistics trays, and fire door core panels in the market occupy a large market share. In recent years, glass magnesium materials hav...

Problems solved by technology

The disadvantage of the extrusion molding device with the above structure is: since the two pressing screws are independent of each other, when it is necessary to adjust the distance between the upper and lower extrusion rollers by adjusting the position of the upper extrusion roller, two workers are required at the same time. It is very inconvenient to adjust the two pressing screws at both ends of the upper extrusion roller, and it is very inconvenient to adjust the two pressing screws independently, so that the axis lines of the upper and lower extrusion rollers are prone to inaccuracies. The parallel phenomenon affects the uniformity of the sheet thickness; in addition, there is no display device for displaying the distance between the upper and lower extrusion rollers in the entire extrusion molding device, so it is difficult to adjust the specified sheet thickness
