Abstract

The invention relates to a paper funeral and interment sacrifice article which is molded by a mold in a paper pulp state, has vivid image, is very light and convenient, has low manufacturing cost, is easy to burn after ceremony, and accords with national traditional culture. The existing funeral sacrifice articles are made of bamboo and wood skeletons and externally pasted paper, and the shape is abstract and rough. In recent years, the funeral and interment sacrifice article which is formed by utilizing foamed plastics and plastic uptake has high cost and is not easy to burn, thereby influencing the environment. The invention relates to a special device which is invented by using waste paper as a raw material and adopting a paper pulp molding process. The equipment integrates the forming, shaping and drying into a whole, belongs to the initiative of the pulp molding industry, and can produce large-scale pulp molding other products with a single cavity by replacing a mold.

Description

Method for manufacturing paper funeral sacrifice article by paper pulp molding process and special equipment

Technical Field

The invention belongs to the funeral and interment sacrifice industry, and particularly relates to a paper funeral and interment sacrifice article manufactured by a paper pulp molding process.

Background

The existing funeral sacrifice articles are made of bamboo skeleton outer pasting paper, and the product is abstract and rough in shape. In recent years, there is a product formed by using foamed plastic or plastic, which is not easy to be incinerated and causes environmental pollution.

At present, the pulp molding industry generally produces products with multiple cavities and projection areas not larger than one square meter, and the prior art cannot produce large products with single cavity.

Disclosure of Invention

The invention aims to invent a method for manufacturing funeral and interment products aiming at the defects in the prior industry.

The paper product is molded by utilizing scanning sampling and numerical control machine tools, and the paper product is molded by utilizing the mold in a paper pulp state, so that the shape is vivid.

The funeral and interment sacrifice articles have a larger body and belong to a single cavity, and a new device and a new technology are needed to be invented for producing the articles by utilizing a paper pulp molding process technology.

The invention adopts the following technical scheme to realize the purpose, and a net mold which can be removed to work independently is attached to a forming mold.

After the wet paper blank is formed, the wet paper blank is carried by the net die and separated from the forming entity die, and the wet paper blank is attached to the net die to be transferred, so that the problems that the wet strength of the large wet paper blank with a single cavity is low and the wet paper blank cannot be transferred are solved.

The wet paper blank is carried by the net mold and transferred into the heat setting mold cavity.

The heat setting mold consists of two symmetrical female molds.

The forming machine forms two symmetrical wet paper blanks at one time.

Two symmetrical wet paper blanks are carried by the net mold and enter the cavity of the heat setting mold together.

After the heat setting mold is closed, two wet paper blanks carried by the net mold into the heat setting mold cavity constitute one cavity.

High-temperature high-pressure gas is injected into a cavity formed by the two wet paper blanks.

The two wet paper blanks are separated from the net mold and attached to the cavity wall of the heat setting mold under the action of high-temperature and high-pressure gas.

The wet paper blank is shaped and dried into a product under the combined action of high-temperature high-pressure gas and a heat shaping mold cavity.

And opening the heat setting mold and taking out the net mold and the product.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

And (4) removing the sealing and pressing bracket 6, installing a forming die 11 attached with the net die 5 on the die seat 4, and pressing the sealing and pressing bracket 6.

And starting the lifting mechanism 1, and enabling the whole set of mould to enter the slurry tank 9 and be immersed in the slurry.

The vacuum is activated and is transferred to the mold 11 through the vacuum port 13.

The slurry passes through a wire die 5 and a forming die 11 to form a wet mat 12.

And starting the lifting mechanism 1 to lift out the whole set of mould.

The transmission mechanism 8 is started, the sealing and pressing bracket 6 is removed, and the net mold 5 is taken out to carry the wet paper blank 12.

The die holder 4 simultaneously forms two wet paper blanks 12 in two directions.

The two net moulds 5 carrying the wet paper blanks 12 are loaded into the hot-press forming mould 18 through the net mould transfer guide rail 3.

And (4) closing the hot-pressing forming die 18, and locking the locking fixture 15.

Hot-pressure gas is injected into the product space 20 through the hot-pressure gas inlet 14.

The wet paper blanks 12 are stripped from the net mould 5 by the hot-pressing gas, so that the two wet paper blanks 12 are pressed onto the two hot-pressing shaping moulds 8 for shaping.

The hot-pressing gas is filled in the product producing space 20 to dry the two wet paper blanks 12, and the moisture in the wet paper blanks 12 is discharged from the gas-water separator 21.

And (4) loosening the locking fixture 15, opening the hot-pressing shaping mold 18, and taking out the net mold 5 and the product 17 to finish a working cycle.
