A polymer composite cardboard and its production equipment

Abstract

The invention discloses a polymer composite cardboard and its production equipment, relates to the technical field of cardboard production equipment, specifically a polymer composite cardboard, including a main core layer, the upper and lower sides of the main core layer are covered There is a glued layer, and the upper and lower sides of the main core layer are respectively bonded with a surface paper layer and a bottom paper layer through the glued layer. The polymer composite cardboard production equipment, when producing composite cardboard, drives the drive screw on the output shaft to rotate through the forward and reverse drive motor, and drives the two drive screws through the timing pulley and the transmission timing belt. Rotate to drive the evenly distributed short fiber spray guns on the outside of the two driving screws to reciprocate. When the main core layer moves, the fiber filaments are sprayed on the surface of the main core layer to improve the toughness of the composite cardboard product. The threads on the outside of the other two driving screws are mutually The staple fiber lances are counter-rotating and the two drive screws are distributed in a cross pattern.

Description

technical field [0001] The invention relates to the technical field of cardboard production equipment, in particular to a polymer composite cardboard and its production equipment. 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 and is used for postcards, cards, picture album backing paper, etc. 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 the cardboard is different from that of ordinary coated paper. The surface is coated with paint. The paper first passes through the drying box, and in a semi-dry state, it passes through a large-diameter chrome-plated dryer with a mirror-like surface. The coating replicates the surface of the cylinder during the drying process to form a smooth surface; it is mainly used in printing advanced Book covers and illust...

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
