AI Technical Summary

Technical Problem

The lack of automated equipment for producing paper bottles in the current technology results in low production efficiency of pulp-molded bottles.

Method used

A paper bottle production equipment was designed, including a forming station, a hot pressing station, and a transfer station. It adopts a paper bottle wet preform forming device and a hot pressing shaping device. Multiple sets of molds are used to realize the automated forming and hot pressing shaping of paper bottle wet preforms. Combined with a pressure-accumulating elastic bag body control mechanism, pressure is applied to the paper bottle wet preforms to achieve seamless one-piece forming.

Benefits of technology

It improves the automation level of paper bottle production, ensures molding efficiency and quality, solves the problem of difficult mold opening at the inverted position, and enhances the strength and durability of paper bottles.

Abstract

The present invention provides a paper bottle production device, which is provided with a paper bottle wet blank forming device and a paper bottle hot pressing and shaping device. The paper bottle wet blank forming device includes a forming machine frame, a slurry tank, a forming upper die member, a forming lower die member and a forming air source pump body; the paper bottle hot pressing and shaping device includes a hot pressing machine frame, a hot pressing upper die member, a hot pressing lower die member, a pressure accumulating type elastic bag body control mechanism and a hot pressing air source pump body; the forming upper die member and the forming lower die member are combined in the slurry tank to prepare a paper bottle wet blank, the forming upper die member and the forming lower die member leave the slurry tank and are separated, the forming upper die member transfers the paper bottle wet blank adsorbed thereon to the hot pressing lower die member, the hot pressing upper die member and the hot pressing lower die member are combined, and the pressure accumulating type elastic bag body control mechanism works and enters the interior of the paper bottle wet blank to apply an outward pressure to the paper bottle wet blank, and the paper bottle wet blank is hot pressed and shaped to form a paper bottle product. The paper bottle production device of the present invention can automatically produce paper bottles.
