Embodiment 1

[0031] Take 100 kg of waste paper, 30 kg of plant fiber-containing waste such as straw and sawdust, crush and soak it into a slurry, filter and remove water to make it reach a semi-dry state where it can be kneaded by hand without water; then take a semi-dry state Pour x kg of slurry into the special outer mold for making paper drums (the amount added depends on the size and thickness of the paper drums to be made), the outer mold used is a wire mesh steel mold, and the mold wall is provided with A plurality of internal and external passages, the diameter of which is 0.1-0.4mm. Press the special inner mold made into the outer mold through a special press, and the inner mold used is a steel mold with Teflon material sprayed on the surface and a high degree of smoothness. The slurry is pressed into the blank by squeezing and draining water; then the blank is finely pressed and dried (the temperature is controlled at 120-150°C) with a special inner mold with a built-in heating el...

Embodiment 2

[0033] Take 100 kg of waste paper, 20-30 kg of plant fiber-containing waste such as straw and sawdust, crush and soak into a slurry, add a part of cornstarch after filtering, stir and knead into a pulp dough, and then take x kg of pulp dough and pour Into the special outer mold for making cartons (the amount added depends on the size and thickness of the carton to be made), the outer mold is a wire mesh steel mold, and the mold wall is provided with a number of channels that run through the inner wall up and down. The diameter of the channel is 0.1-0.4mm. Press the special inner mold made into the outer mold through a special press, and the inner mold used is a steel mold with Teflon material sprayed on the surface and a high degree of smoothness. The slurry is pressed into the blank by squeezing and draining water; then the blank is finely pressed and dried (the temperature is controlled at 120-150°C) with a special inner mold with a built-in heating element; finally, a compo...

Abstract

The invention provides a prepare method of paper setting products. It contains the steps of preparing slurry, quantitatively inject slurry, discharge pressing initial blank, press drying and forming and knockout extraction etc. The materials of the paper setting products in this invention are cheap and easy to get. It can realize waste utilization, short technological process, products integration, without combination or binder. The products are more firm and practical. It also reduces and eliminates the environmental pollution.

Description

technical field [0001] The invention relates to a method for making light industrial products, in particular to a method for making paper shaped products. Background technique [0002] Pulp is the raw material for the production of various papers. After pulping, mesh filtration, rolling, drying, and glazing, paper pulp can be made into various papers of different qualities and specifications for writing, packaging, and supplying various types of paper. Use when necessary. However, to make paper shaped products such as paper pads, paper boxes, paper barrels, paper trays, etc., it is necessary to paste, fold, glue and assemble the paper layer by layer. For example: [0003] The production methods of paper barrels include the following two methods: one method is to stick straw pulp paper or kraft paper into cardboard layer by layer, then cut, roll the barrel, and then use multi-layer plywood to make the top cover and the bottom of the barrel respectively. Then use two iron h...
