Description

Technical Field

[0001] This utility model relates to the field of pulp molding technology, and in particular to a multi-station pulp molding device. Background Technology

[0002] As a core production device for environmentally friendly packaging products, pulp molding equipment's molding process flexibility directly impacts product diversity, quality, and production costs. Existing technologies using reciprocating molding machines with two molds (upper molding mold and upper hot-pressing mold) and three stations only support two mold combination methods (one is the combination of the lower molding mold and the upper molding mold, or the lower hot-pressing mold and the upper hot-pressing mold; the other is a combination of the upper molding mold and the lower hot-pressing mold). These devices have the following significant drawbacks: poor process adaptability, a limited range of mold combination methods, and an inability to meet the increasingly complex product shapes and functional requirements of the current market. High equipment modification costs: when new mold combination methods are needed for product processes, the original equipment must be mechanically modified or new equipment must be purchased, significantly increasing the customer's production investment. Furthermore, limited by the aforementioned fixed mold combination, the equipment cannot dynamically adjust the mold combination methods during the molding and hot-pressing stages according to raw material characteristics and product requirements, further leading to problems such as insufficient product stiffness and weak fiber bonding, reducing product qualification rates and market competitiveness.
