Polymer composite paperboard and production equipment thereof

Abstract

The invention discloses a polymer composite paperboard and production equipment thereof, and relates to the technical field of paperboard production equipment, in particular to a polymer composite paperboard which comprises a main core layer, the upper side and the lower side of the main core layer are both covered with gluing layers, and the upper side and the lower side of the main core layer are connected with a surface paper layer and a bottom paper layer in a glued mode through the gluing layers respectively. According to the polymer composite paperboard production equipment, when composite paperboards are produced, the driving screw rods on the output shaft are driven to rotate through the forward and reverse rotation driving motor, transmission is conducted through the synchronous belt wheel and the transmission synchronous belt, the two driving screw rods are driven to rotate, and the short fiber spray guns evenly distributed outside the two driving screw rods are driven to reciprocate; when the main core layer moves, cellosilk is sprayed on the surface of the main core layer, so that the toughness of a finished product of the composite paperboard is improved, threads outside the other two driving screw rods rotate reversely, and short fiber spray guns outside the two driving screw rods are distributed in a crossed manner.

Description

technical field [0001] The invention relates to the technical field of paperboard production equipment, in particular to a polymer composite paperboard and production equipment thereof. Background technique [0002] Cardboard is a general term for a kind of thick paper between paper and cardboard. It weighs more than 120 grams per square meter. It is used for postcards, cards, album lining paper, etc. There are various types of cardboard. Glass cardboard is generally White, the whiteness is above 85%, and some products are colored. The cardboard has extremely high smoothness, gloss, and high stiffness. The production process of cardboard is different from ordinary coated paper. It is coated with paint on the surface. The paper first passes through the drying oven, and in a semi-dry state, it passes through a large-diameter chrome-plated drying cylinder with a mirror-like surface. The coating replicates the surface of the cylinder during the drying process to form a smooth su...

AI Technical Summary

Problems solved by technology

Existing paperboards are usually made by pressing aluminum foil and other surface paper directly on the surface of the bottom paper through equipment after gluing the bottom paper to form a composite paper product. Although this kind of composite paper has improved aesthetics, its overall toughness is low. When the composite paper is reprocessed, it is easy to cause wrinkles or even breakage at the bend of the composite paper. In addition, the existing composite paper processing equipment directly rolls up the composite paper after gluing each layer, and the adhesive is not completely dry. , during subsequent storage, it is easy to cause wrinkles and mildew on the composite paper. Therefore, we propose a polymer composite paperboard and its production equipment to solve the above-mentioned problems
