Description

A suction mold for pulp molding technical field

The utility model relates to the technical field of pulp molding, in particular to a pulp suction mold for pulp molding.

Background technique

Pulp molded products (or called paper and plastic products) are products that use pulp as raw material and are molded by suction and compression molding, such as support objects in mobile phone packaging shells. Because its finished products can be recycled and remanufactured, it conforms to the energy-saving trend of environmental protection and reuse, so it has attracted widespread attention and favor in the market, so more and more attention has been paid to the processing equipment used to make it, and the market competition is particularly fierce.

The vacuum suction filtration forming process of pulp molded products can generally be divided into two stages: the blank forming (forming parison) stage and the dehydration stage. The blanking stage is strictly a filtering stage. During this process, the solid slurry is mainly adsorbed on the surface of the filter medium by means of vacuum, and gradually forms a parison with a certain thickness; as the parison gradually thickens, the corresponding filtration resistance gradually increases until a parison with a certain thickness is formed. Therefore, the filtration rate at this stage is gradually decreasing.

For example, the publication number is CN209128813U, the title is "A Pulp Suction Mold Suitable for Pulp Molding", and the authorized announcement date is a utility model patent of 20190719, which particularly relates to a slurry suction mold suitable for pulp molding. One side of the groove is provided with a groove, and the side opposite to the bottom surface of the groove is the mold surface, the mold surface is provided with a mesh plate, and the side wall of the groove is provided with suction holes, so that the effect of dehydrating the parison exceeding the limit thickness is better. Well, it can make the quality of paper-plastic products exceeding the limit thickness meet the requirements, and the structure is simple, the cost is low, and the cost of transforming the existing equipment system is also relatively low.

The disadvantage of the prior art including the above-mentioned patents is that as the thickness increases, the dehydration effect of the parison becomes worse and worse, and the generated suction is not uniform enough, resulting in the quality of the finished product being difficult to meet the requirements. And if the performance of the vacuum suction equipment is increased to improve the dehydration effect.
