Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an automatic pulp molding device. Background Technology

[0002] Pulp molding products are formed using molds in the pulp state. They can produce complex and precise pulp boxes, which are widely used as packaging and protective products and have excellent development prospects. Automatic pulp molding equipment is currently a common device for producing pulp molding products. It generally includes a molding section and a setting section to complete the molding and setting of the pulp molding product, respectively. Existing automatic pulp molding equipment typically only has one molding section and one setting section. Because setting takes a relatively long time, the molding section is in a waiting state for an extended period, and manual unloading of the finished product is required. This results in low production efficiency for automatic pulp molding equipment and seriously affects delivery time.

[0003] In existing automatic pulp molding devices, the molding die assembly is arranged in a straight line between two hot pressing dies. When the lower hot pressing die moves to the middle to receive the wet blank, it is directly above the molding pulp tank. During continuous production, some carbon deposits and dirt from the lower hot pressing die fall into the molding pulp tank below. In addition, during the hot pressing process, steam is generated due to the mold closing pressure and temperature of about 200 degrees Celsius, which causes some carbon deposits and dirt to be carried into the molding pulp tank, affecting product quality and reducing the product qualification rate.
