Paper-plastic three-dimensional structure manufacturing technique

Abstract

A paper plastic multiplex structure manufacturing technology includes putting a paper plastic mould into a slash box, and the paper plastic mould is suctioned by a suctioning channel, and a finished body is dehydrated and makes the paper plastic multiplex structure. Wherein, the paper plastic mould includes an upper mould and a lower mould which match in shape; the upper mould is superposed on the lower mould; spacing for paper pulp to pass is left between the upper and the lower moulds; the surface of the paper plastic mould is provided with a plurality of suctioning holes; at least partial suctioning holes are provided with suctioning channels so as to suction to the paper plastic mould. The technology is characterized in that the invention correspondingly superposes the upper and the lower moulds and suctions to the suctioning holes arranged on the moulds; the technology is novel and unique with high finished product rate; the paper plastic multiplex structure does not adopt any paper-making mesh, so no mesh line is produced on the surface of the product and the degree of finish is high; the paper plastic multiplex structure can be provided with a large number of concave and convex structure, so the applicable of the product is wide; the invention adopts the rotational technology, which brings more even suctioning; the rotational technology of the invention can be conducted at the same time with suctioning, so the production efficiency is high.

Description

technical field [0001] The invention relates to a manufacturing process of a novel paper-plastic three-dimensional structure, in particular to a manufacturing process of a paper-plastic container for an electronic device, and the paper-plastic container manufactured by the process. Background technique [0002] The paper-plastic three-dimensional structure, that is, the paper-plastic container, is often used in food packaging, electronic device packaging, etc., with a wide range of applications and a large demand. [0003] The publication number CN2317075 describes a paper container compression molding device, which mainly includes a vertically movable male module and a female module. Forming a relatively matched rib block, the utility model utilizes the male module and the female module to be matched and extruded, and the paper container with the partition rib is formed by direct compression molding. However, this compression molding process is only suitable for the format...

Problems solved by technology

First of all, for the papermaking process, the commonly used papermaking net is easy to produce lines on the surface of the product, and there is no more effective way to solve the surface finish of the product; second, the traditional process can only process paper-plastic containers with relatively simple shapes , because the papermaking net is difficult to fix on the mold with complex structure, and it is not easy to disassemble if the integrally welded papermaking net is used; third, the papermaking net cannot be completely screened; fourth, the traditional pulp suction process adopts fixed suction, Only apply negative pressure to one direction of the mold, which is easy to cause uneven thickness of the product
