AI Technical Summary
Technical Problem
In existing environmentally friendly tableware production technologies, the paper sheets formed after pulping need to be dried or re-wetted, which leads to complex processes, difficulty in forming continuous production, high energy consumption, low production efficiency, and high costs.
Method used
The direct-pressure production process involves pulping, mixing, and supplying pulp, followed by three-stage roll pressing and dewatering to form a semi-dry paper web. The web is then directly cut on a roll cutter and hot-pressed in a setting equipment, avoiding the drying and rewetting steps.
Benefits of technology
It enables continuous production processes, reduces energy consumption, improves production efficiency, and lowers production costs.

Abstract
The present application relates to the technical field of environment-friendly tableware manufacturing, and provides a process and equipment for directly pressing tableware, which comprises the steps of pulp preparation, pulp mixing and pulp supply, semi-dry paper web forming, wet paper web roll cutting and hot pressing. The process for directly pressing tableware provided by the present application firstly performs pulp preparation, pulp mixing and pulp supply; then the pulp after pulp preparation is transported to a paper machine to form a semi-dry wet paper web through at least three-stage roll pressing and dewatering; then the semi-dry wet paper web is transported to a roll cutting machine to form a wet pressing paper blank and corner waste through roll cutting; the wet pressing paper blank is transported to a setting equipment to form a tableware product and corner material through hot pressing; and the semi-dry wet paper web can be directly roll cut into a wet pressing paper blank on the roll cutting machine without drying, and the wet pressing paper blank can be directly hot pressed into a tableware product on the setting equipment without re-wetting, so that the process is simple, a continuous production process can be formed, energy consumption is lower, production efficiency is higher, and production cost is lower.
