Abstract

The invention relates to an extrusion mold for molding an integral bottle of pulp and an extrusion process thereof. The extrusion die is composed of an extrusion die, a pressurized cavity, an elastomer bag, a slurry suction mold, and the wet embryo after slurry suction; the bottle is pressed in the extrusion mold by a pre-pressing mold using an elastomer bag Make pre-pressed wet embryos, control the pre-pressed pressure to ensure the moisture content and thickness of the paper bottle wet embryos, and then form them into paper-plastic bottles by hot pressing.

Description

technical field [0001] The invention relates to the technical field of forming paper-plastic molded products, in particular to the development of an extrusion die for a paper-plastic integral bottle. Background technique [0002] The existing technology of paper-plastic bottle products is to use two half-sided bottles to be formed and then glued with glue, or to use a paper tube to glue the bottle mouth and the bottle bottom. The processes are forming, gluing, pressing, cutting. For the rest, such as the patent CN201320746431, a paper-plastic bottle body is disclosed, which includes a bottle body and a plastic end head arranged on the upper part of the bottle body, the bottle body is a paper tube with an upward opening, and the lower edge of the plastic end head is connected with the plastic end head. The opening of the paper tube is tightly joined to close the inner cavity of the paper tube; Patent CN 201420833805 discloses a liquid storage bottle with a connecting ring, in...
