Production technology and production equipment for product paper shell

Abstract

The invention discloses a production technology and production equipment for a product paper shell. The production technology comprises the steps that firstly, Dupont paper and a plastic rubber sheetare cut into a first Dupont paper layer, a plastic rubber sheet layer and a second Dupont paper layer according to the needed shape size, the first Dupont paper layer, the plastic rubber sheet layer and the second Dupont paper layer are glued together through hot melting glue, and a waterproof abrasion resisting rough paper board is formed; secondly, the waterproof abrasion resisting rough paper board obtained in the first step is placed on a forming male die in a vacuum adsorption groove; thirdly, at the time, high-temperature steam is used for heating and humidifying the waterproof abrasionresisting rough paper board through a steam baking disc, vacuum pumping is conducted after a vacuum silica gel layer is downwards in butt joint with the vacuum adsorption groove for seal, the waterproof abrasion resisting rough paper board is wrapped and tensioned on the forming male die, meanwhile, a forming female die downwards applies a certain pressure to the waterproof abrasion resisting rough paper board, and a paper shell product is formed under the action of the dies; and fourthly, after pressing is finished, the dies return to the original positions, and the paper shell product is taken down from the dies. The paper shell product is resistant to tearing, waterproof, resistant to abrasion, light in texture, resistant to corrosion, free of peculiar smells and capable of being widelyapplied to consumption product decoration shells and structure components.

Description

technical field [0001] The invention relates to the technical field of paper shell processing technology, in particular to a production process of a product paper shell and production equipment thereof. Background technique [0002] With the continuous development and strengthening of my country's manufacturing industry, it is possible to produce a variety of products, including high-end equipment such as automobiles and ships, as small as handicraft products, rings, paper, and paper processing and production into jigsaw puzzle models, etc. , but the existing technology for paper production and the jigsaw puzzles or three-dimensional model toys made of the produced paper are not waterproof, not wear-resistant, easy to tear and have a short service life. Therefore, DuPont paper appeared on the market. Due to its waterproof and wear resistance, DuPont paper materials are now used in paper wallets, raincoats, clothing washing labels, paper shoes, masks and other practical produc...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a production process and equipment for a product paper shell, which solves the problem of wrinkling when the paper is stretched at the turning point of the rounded corner during the forming of the paper shell, because the paper has no stretching elasticity, and the paper Molding process is a blank issue in the industry
