Abstract

The invention relates to an extrusion die and an extrusion process of a paper-molded integral bottle. The extrusion die is composed of an extrusion die body, a pressurizing cavity, an elastomer bag, apulp suction die body and a pulp-sucked wet blank. According to the bottle, a pre-pressed wet blank is manufactured in the extrusion die through a pre-pressing forming die by applying pressure to theelastomer bag, the water content of the paper bottle wet blank and the thickness of the wet blank are guaranteed by controlling the magnitude of the pre-pressing pressure, and then the paper-molded bottle is formed through 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 glue to bond the two halves of the bottle after forming or use paper tubes to bond the bottle mouth and the bottom of the bottle. The process is forming, gluing, pressing, cutting For the remainder, as patent CN201320746431 discloses a paper-plastic bottle body, comprising a bottle body and a plastic end on the top of the bottle body, the bottle body is a paper tube with an upward opening, and the lower edge of the plastic end is connected to the The openings of the paper tube are tightly joined to seal the inner cavity of the paper tube; patent CN 201420833805 discloses a liquid storage bottle with a connecting ring, including a paper bottle, the inside of which is provided with a l...
